3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA/Quincy Eggert Upside down can be right side up. That’s what NASA researchers determined for tests of an efficient wing concept that could be part of the agency’s answer to making future aircraft sustainable. Research from NASA’s Advanced Air Transport Technology project involving a 10-foot model could help NASA engineers validate the concept of the Transonic Truss-Braced Wing (TTBW), an aircraft using long, thin wings stabilized by diagonal struts. The TTBW concept’s efficient wings add lift and could result in reduced fuel use and emissions for future commercial single-aisle aircraft. A team at the Flight Loads Laboratory at NASA’s Armstrong Flight Research Center in Edwards, California, are using the model, called the Mock Truss-Braced Wing, to verify the concept and their testing methods. The model wing and the strut have instruments installed to measure strain, then attached to a rigid vertical test frame. Wire hanging from an overhead portion of the frame stabilizes the model wing for tests. For these tests, researchers chose to mount the 10-foot-long aluminum wing upside down, adding weights to apply stress. The upside-down orientation allows gravity to simulate the lift a wing would experience in flight. Researchers test a 10-foot Mock Truss-Braced Wing at NASA’s Armstrong Flight Research Center in Edwards, California. A view from above shows the test structure, the wing, and the strut. The aircraft concept involves a wing braced on an aircraft using diagonal struts that also add lift and could result in significantly improved aerodynamics.NASA/Steve Freeman “A strut reduces the structure needed on the main wing, and the result is less structural weight, and a thinner wing,” said Frank Pena, NASA mock wing test director. “In this case, the test measured the reaction forces at the base of the main wing and at the base of the strut. There is a certain amount of load sharing between the wing and the strut, and we are trying to measure how much of the load stays in the main wing and how much is transferred to the strut.” To collect those measurements, the team added weights one at a time to the wing and the truss. In another series of tests, engineers tapped the wing structure with an instrumented hammer in key locations, monitoring the results with sensors. “The structure has natural frequencies it wants to vibrate at depending on its stiffness and mass,” said Ben Park, NASA mock wing ground vibration test director. “Understanding the wing’s frequencies, where they are and how they respond, are key to being able to predict how the wing will respond in flight.” Researchers test a 10-foot Mock Truss-Braced Wing at NASA’s Armstrong Flight Research Center in Edwards, California. Charlie Eloff, left, and Lucas Oramas add weight to the test wing to apply stress used to determine its limits. The aircraft concept involves a wing braced on an aircraft using diagonal struts that also add lift and could result in significantly improved aerodynamics.NASA/Steve Freeman Adding weights to the wingtip, tapping the structure with a hammer, and collecting the vibration response is an unusual testing method because it adds complexity, Park said. The process is worth it, he said, if it provides the data engineers are seeking. The tests are also unique because NASA Armstrong designed, built, and assembled the wing, strut, and test fixture, and conducted the tests. With the successful loads calibration and vibration tests nearly complete on the 10-foot wing, the NASA Armstrong Flight Loads Laboratory team is working on designing a system and hardware for testing a 15-foot model made from graphite-epoxy composite. The Advanced Air Transport Technology TTBW team at NASA’s Langley Research Center in Hampton, Virginia, is designing and constructing the model, which is called the Structural Wing Experiment Evaluating Truss-bracing. The larger wing model will be built with a structural design that will more closely resembles what could potentially fly on a future commercial aircraft. The goals of these tests are to calibrate predictions with measured strain data and learn how to test novel aircraft structures such as the TTBW concept. NASA’s Advanced Air Transport Technology project falls under NASA’s Advanced Air Vehicles Program, which evaluates and develops technologies for new aircraft systems and explores promising air travel concepts.

2 Min Read Turn Supermoon Hype into Lunar Learning Caption: The Earth-Moon distance to scale. Credits: NASA/JPL-Caltech Supermoons get lots of publicity from the media, but is there anything to them beyond the hype? If the term “supermoon” bothers you because it’s not an official astronomical term, don’t throw up your hands. You can turn supermoon lemons into lunar lemonade for your star party visitors by using it to illustrate astronomy concepts and engaging them with great telescopic views of its surface! Many astronomers find the frequent supermoon news from the media misleading, if not a bit upsetting! Unlike the outrageously wrong “Mars is as big as the moon” pieces that appear like clockwork every two years during Mars’s close approach to Earth, news about a huge full moon is more of an overstatement. The fact is that while a supermoon will indeed appear somewhat bigger and brighter in the sky, it would be difficult to tell the difference between an average full moon and a supermoon with the naked eye. A whiteboard illustration of Earth’s Moon at perigee, or closest position to Earth. Credit: NASA There are great bits of science to glean from supermoon discussion that can turn supermoon questions into teachable moments. For example, supermoons are a great gateway into discussing the shape of the moon’s orbit, especially the concepts of apogee and perigee. Many people may assume that the moon orbits Earth in a perfect circle, when in fact its orbit is elliptical! The moon’s distance from Earth constantly varies, and so during its orbit it reaches both apogee (when it’s farthest from Earth), as well as perigee (closest to Earth). A supermoon occurs when the moon is at both perigee and in its full phase. That’s not rare; a full moon at closest approach to Earth can happen multiple times a year, as you may have noticed. This activity is related to a Teachable Moment from Nov. 15, 2017. See “What Is a Supermoon and Just How Super Is It?” Credit: NASA/JPL While a human observer won’t be able to tell the difference between the size of a supermoon and a regular full moon, comparison photos taken with a telephoto lens can reveal the size difference between full moons. NASA has a classroom activity called Measuring the Supermoon where students can measure the size of the full moon month to month and compare their results. Comparison of the size of an average full moon, compared to the size of a supermoon. NASA/JPL-Caltech Students can use digital cameras (or smartphones) to measure the moon, or they can simply measure the moon using nothing more than a pencil and paper! Both methods work and can be used depending on the style of teaching and available resources. /wp-content/plugins/nasa-blocks/assets/images/media/media-example-01.jpg This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula.

Mike Lauer manages production of the RS-25 main engines for NASA’s heavy-lift SLS (Space Launch System), which will launch U.S. astronauts back to the Moon as part of the agency’s Artemis campaign. L3 Harris Technologies Mike Lauer, an engineer who works for the Aerojet Rocketdyne segment of L3Harris Technologies, found his career inspiration in science fiction, but for the perspective it takes to execute complex space programs, he draws on real-world experience. Growing up, Lauer spent many cold winter nights in the basement of his Sioux Falls, South Dakota, home, creating pictures of iconic space hardware from Hollywood space movies. “That really is what got me into it,” he says. Fast forward to today, and he’s managing production of the RS-25 main engines for NASA’s heavy-lift SLS (Space Launch System), which will launch U.S. astronauts back to the Moon as part of the agency’s Artemis campaign. When the scale and complexity of the undertaking appear daunting, Lauer thinks back to early in his career, when he designed hardware for the International Space Station, now in its third decade on orbit. “It just seemed to me that there’s no way this was going to work, but we just kept building and solving problems and the next thing you know, we’re launching space station parts,” Lauer says. “Having that experience of seeing a program that seemed too big, too complex, and it worked, gives me great hope and confidence that we can do it again with Artemis.” Lauer has family ties to space. His father, Don Lauer, ran the U.S. Geological Survey’s Earth Resources Observation and Science Center in Sioux Falls, a repository for data collected by NASA’s long-running Landsat series of land imaging satellites. Lauer’ father even spent time at NASA’s Johnson Space Center in Houston, home to the Agency’s human spaceflight program, exploring the role of astronauts in Earth observation from space. But it was an artist’s fascination with fictional hardware –– that ultimately led Mike Lauer to earn his bachelor and master’s degrees in Aeronautical & Astronautical engineering from Stanford University in Palo Alto, California. “With engineering in general, there’s a connection with art,” Lauer says. “We create these things that have an artistic aesthetic to them, which is really cool.” Cool is a word Lauer, a licensed pilot, deploys frequently in describing his career journey, understandably so. For example, he once participated in a space station assembly rehearsal with veteran astronaut Jerry Ross at Johnson’s Neutral Buoyancy Facility, a giant pool used to help train astronauts for spacewalks. “I’m in this spacesuit and Jerry Ross is in this spacesuit and we’re plugging in elements of the space station,” Lauer says, almost in disbelief. “Oh my gosh!” While serving as Aerojet Rocketdyne’s lead engineer on the Multi Mission Radioisotope Thermo-electric Generator program, Lauer visited the U.S. Department of Energy’s Idaho National Laboratory to observe the loading of Plutonium 238 nuclear fuel into the device, which continues to power NASA’s car-sized Curiosity rover on the Martian surface. “Super cool,” he says. For his next move, Lauer figured that, being at Aerojet Rocketdyne (now L3Harris), builder of the engines on NASA’s legendary Saturn V Moon rocket, he should get into the propulsion side of the business. He began on the J-2X, a modified version of the Saturn V’s second stage engine that NASA had planned at one point to use on the SLS. Working from 1960s era drawings, Lauer and his team created a modern, easier-to-produce design with more power that had a successful series of hot-fire tests before being replaced in favor of a different upper stage design. Now, as RS-25 program director, Lauer works on another engine, this one originally designed for NASA’s now-retired Space Shuttle, updating and redesigning key components to meet new requirements and reduce production costs. The SLS flew its first mission without a crew, but upcoming flights will have astronauts aboard, which gives Lauer a huge sense of pride and responsibility. “I’m awed and inspired by what we’re doing,” he says. “Really cool.” Also really cool: Lauer serves as a volunteer pilot for the Civil Air Patrol, supporting the U.S. Air Force on search and rescue, disaster relief, and fire damage assessment missions. That keeps him busy on many weekends when he’s not refereeing youth soccer. Aside from that, Lauer most looks forward to the day four NASA astronauts are safely aboard their recovery ship at the successful conclusion of the first human moon landing in more than five decades.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The UAVSAR underbelly pod is in clear view as NASA’s Gulfstream-III research aircraft banks away over Edwards AFBNASA On a changing planet, where phenomena like severe hurricanes, landslides, and wildfires are becoming more severe, scientists need data to assess and model disaster impacts and to potentially make predictions about hazards. NASA’s C-20A aircraft is a significant asset that can carry key instruments for understanding the science behind these phenomena. Based at NASA’s Armstrong Flight Research Center in Edwards, California, the C-20A is a military version of the Gulfstream III business jet and operates as an airborne science aircraft for a variety of Earth science research missions. In October, the plane was deployed to fly over areas affected by Hurricane Milton. With winds of up to 120 miles per hour, the hurricane hit the Florida coast as a category 3 storm, and produced lightning, heavy rainfall, and a series of tornadoes. In the aftermath of the storm, the C-20A was outfitted with the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument to collect detailed data about the affected flood areas. “Our team focused specifically on inland river flooding near dense populations, collecting data that could help inform disaster response and preparation in the future,” said Starr Ginn, C-20A aircraft project manager. “By all indications, this rapid response to support Hurricane Milton recovery efforts was a successful coordination of efforts by science and aircraft teams.” The Uninhabited Aerial Vehicle Synthetic Aperture Radar, UAVSAR, is prepared for installation onto NASA’s C-20A aircraft. THE UAVSAR uses a technique called interferometry to detect and measure very subtle deformations in the Earth’s surface, and the pod is specially designed to be interoperable with unmanned aircraft in the future. It will gather data from Gabon, Africa in September of 2023.NASA/Steve Freeman The UAVSAR was developed by NASA’s Jet Propulsion Laboratory in Southern California, and uses a technique called interferometry to detect subtle changes to Earth’s surface. Interferometry uses the intersection of multiple wavelengths to make precise measurements. This detection system effectively measures the terrain changes or impacts before and after an extreme natural event. When flown onboard an aircraft, radars like the UAVSAR can also provide more detail than satellite radars. “Where satellite instruments might only get a measurement every one to two weeks, the UAVSAR can fill in points between satellite passes to calibrate ground-based instruments,” Ginn said. “It takes data at faster rates and with more precision. We can design overlapping flights in three or more directions to detect more textures and motions on the Earth’s surface. This is a big advantage over the one-dimensional line-of-sight measurement provided by a single flight.” The C-20A team also used the UAVSAR in October to investigate the Portuguese Bend landslide in Rancho Pales Verdes. The Portuguese Bend Landslide began in the mid- to late-Pleistocene period over 11,000 years ago. Though inactive for thousands of years, the landslide was reactivated in 1956 when a road construction project added weight to the top of it. Recently, the landslide has been moving at increasing rates during dry seasons. NASA’s JPL scientists, Xiang Li, Alexander Handwerger, Gilles Peltzer, and Eric Fielding have been researching this landslide progression using satellite-based instruments. “The high-resolution capability of UAVSAR is ideal for landslides since they have relatively small features,” said Ginn. “This helps us understand the different characteristics of the landslide body.” NASA flew an aircraft equipped with Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) flew above California fires on Sept. 3 and 10, 2020.NASA/JPL-Caltech The C-20A airborne observatory also provided crucial insight for studies of wildfire. The Fire and Smoke Model Evaluation Experiment (FASMEE), a multi-agency experiment led by the U.S. Department of Agriculture’s Forest Service Pacific Northwest Research Station, included flights of the C-20A. This experiment studied fire behavior and smoke. “The airborne perspective allows FASMEE researchers to better understand fire behavior and smoke production,” said Michael Falkowski, program manager for NASA’s Applied Sciences Wildland Fire program. “Hopefully this data will help mitigate fire risk, restore degraded ecosystems, and protect human communities from catastrophic fire.” Airborne data can inform how scientists and experts understand extreme phenomena on the ground. Researchers on the FASMEE experiment will use the data collected from the UAVSAR instrument to map the forest’s composition and moisture to track areas impacted by the fire, and to study how the fire progressed. “We can explore how fire managers can use airborne data to help make decisions about fires,” added Jacquelyn Shuman, FireSense project scientist at NASA’s Ames Research Center in California’s Silicon Valley.

4 min read Expanded AI Model with Global Data Enhances Earth Science Applications On June 22, 2013, the Operational Land Imager (OLI) on Landsat 8 captured this false-color image of the East Peak fire burning in southern Colorado near Trinidad. Burned areas appear dark red, while actively burning areas look orange. Dark green areas are forests; light green areas are grasslands. Data from Landsat 8 were used to train the Prithvi artificial intelligence model, which can help detect burn scars. NASA Earth Observatory NASA, IBM, and Forschungszentrum Jülich have released an expanded version of the open-source Prithvi Geospatial artificial intelligence (AI) foundation model to support a broader range of geographical applications. Now, with the inclusion of global data, the foundation model can support tracking changes in land use, monitoring disasters, and predicting crop yields worldwide. The Prithvi Geospatial foundation model, first released in August 2023 by NASA and IBM, is pre-trained on NASA’s Harmonized Landsat and Sentinel-2 (HLS) dataset and learns by filling in masked information. The model is available on Hugging Face, a data science platform where machine learning developers openly build, train, deploy, and share models. Because NASA releases data, products, and research in the open, businesses and commercial entities can take these models and transform them into marketable products and services that generate economic value. “We’re excited about the downstream applications that are made possible with the addition of global HLS data to the Prithvi Geospatial foundation model. We’ve embedded NASA’s scientific expertise directly into these foundation models, enabling them to quickly translate petabytes of data into actionable insights,” said Kevin Murphy, NASA chief science data officer. “It’s like having a powerful assistant that leverages NASA’s knowledge to help make faster, more informed decisions, leading to economic and societal benefits.” AI foundation models are pre-trained on large datasets with self-supervised learning techniques, providing flexible base models that can be fine-tuned for domain-specific downstream tasks. Crop classification prediction generated by NASA and IBM’s open-source Prithvi Geospatial artificial intelligence model. Focusing on diverse land use and ecosystems, researchers selected HLS satellite images that represented various landscapes while avoiding lower-quality data caused by clouds or gaps. Urban areas were emphasized to ensure better coverage, and strict quality controls were applied to create a large, well-balanced dataset. The final dataset is significantly larger than previous versions, offering improved global representation and reliability for environmental analysis. These methods created a robust and representative dataset, ideal for reliable model training and analysis. The Prithvi Geospatial foundation model has already proven valuable in several applications, including post-disaster flood mapping and detecting burn scars caused by fires. One application, the Multi-Temporal Cloud Gap Imputation, leverages the foundation model to reconstruct the gaps in satellite imagery caused by cloud cover, enabling a clearer view of Earth’s surface over time. This approach supports a variety of applications, including environmental monitoring and agricultural planning. Another application, Multi-Temporal Crop Segmentation, uses satellite imagery to classify and map different crop types and land cover across the United States. By analyzing time-sequenced data and layering U.S. Department of Agriculture’s Crop Data, Prithvi Geospatial can accurately identify crop patterns, which in turn could improve agricultural monitoring and resource management on a large scale. The flood mapping dataset can classify flood water and permanent water across diverse biomes and ecosystems, supporting flood management by training models to detect surface water. Wildfire scar mapping combines satellite imagery with wildfire data to capture detailed views of wildfire scars shortly after fires occurred. This approach provides valuable data for training models to map fire-affected areas, aiding in wildfire management and recovery efforts. Burn scar mapping generated by NASA and IBM’s open-source Prithvi Geospatial artificial intelligence model. This model has also been tested with additional downstream applications including estimation of gross primary productivity, above ground biomass estimation, landslide detection, and burn intensity estimations. “The updates to this Prithvi Geospatial model have been driven by valuable feedback from users of the initial version,” said Rahul Ramachandran, AI foundation model for science lead and senior data science strategist at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “This enhanced model has also undergone rigorous testing across a broader range of downstream use cases, ensuring improved versatility and performance, resulting in a version of the model that will empower diverse environmental monitoring applications, delivering significant societal benefits.” The Prithvi Geospatial Foundation Model was developed as part of an initiative of NASA’s Office of the Chief Science Data Officer to unlock the value of NASA’s vast collection of science data using AI. NASA’s Interagency Implementation and Advanced Concepts Team (IMPACT), based at Marshall, IBM Research, and the Jülich Supercomputing Centre, Forschungszentrum, Jülich, designed the foundation model on the supercomputer Jülich Wizard for European Leadership Science (JUWELS), operated by Jülich Supercomputing Centre. This collaboration was facilitated by IEEE Geoscience and Remote Sensing Society.

Credits: NASA/Stennis Explore Lagniappe for December 2024 featuring: NASA Stennis Secures Grant for Clean Energy Project Powering Space Dreams NASA Builds Bridges at Bayou Classic Gator Speaks Gator SpeaksNASA/Stennis Do you have time for a quick story? Recently, your ol‘ friend Gator had the chance to help his family move. This move was not the same as going to the Moon or Mars like NASA’s planned Artemis adventure, but it felt similar. The move brought friends, family, and even some neighbors together to help. Each person took on a role in an organized way to help make it happen. Some packed, others cleaned, and all contributed in some way, with each person bringing his or her special touch to the project. We were not just working hard. We were making the most of it. It became more than work. It turned into a celebration of friends and family coming together to make something good happen. There was something truly rewarding about seeing everyone pitch in to make it a success. While this move will not take us to the Moon like the Artemis campaign, it is hard not to see similarities. When NASA returns to the Moon for scientific discovery, technology advancement, and to learn how to live and work on another world while preparing for human missions to Mars, it will be a success for all of us to share in. Through Artemis, NASA is bringing together commercial and international partners to establish the first long-term presence on the Moon. Here at NASA Stennis, many are working hard to help prepare the agency for future Artemis missions, testing needed rocket engines and systems. Going back to the Moon has become more than work, though. It is inspiring a new generation of explorers – the Artemis Generation. Every person is playing a role. It is bringing together friends, family, and neighbors to help. All are contributing, with each person bringing a special touch to the mission. It is a celebration of each step forward, each rocket launched, each mission accomplishment. Each milestone reminds us all – “Wow, we really did that. We are a part of something great.” > Back to Top NASA Stennis Top News NASA Stennis Secures Grant for Clean Energy Project NASA’s Stennis Space Center has been awarded a highly competitive U.S. Department of Energy grant to transform its main administration building into a facility that produces as much renewable energy as it uses.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Jeff Renshaw is the lead attorney for procurement law in the Office of the General Counsel for NASA’s Stennis Space Center and the NASA Shared Services Center. NASA/Danny Nowlin NASA attorney Jeff Renshaw’s work has primarily revolved around two things: serving others and solving problems. The New Orleans native retired as an U.S. Air Force judge advocate following more than two decades of service. Renshaw now has worked for more than eight years as an attorney advisor at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. As the nation’s largest multiuser propulsion test site, NASA Stennis supports and helps power both national and commercial space efforts and missions. Any activity at NASA Stennis is authorized by some form of written agreement. The Office of General Counsel, which Renshaw is a part of, works to ensure that work is conducted appropriately. “I’m dedicated to being the best public civil servant I can be,” Renshaw said. “In this position, you are representing your client, which is NASA, the federal government, and the taxpayers, so it is important for me to stay updated with the latest legal developments to be the best advocate and advisor I can be.” As lead attorney for procurement law, the Metairie, Louisiana, resident works alongside the Office of Procurement serving both NASA Stennis and the NASA Shared Services Center. Some of Renshaw’s work includes reviewing Space Act contract agreements for commercial companies that use NASA Stennis facilities, along with activities for some of the more than 50 federal, state, academic, public, and private aerospace, technology, and research organizations that are part of the NASA Stennis federal city. Renshaw is motivated to be an expert in his line of work – whether deployed as a U.S. Air Force procurement law attorney to Baghdad, the Horn of Africa, and Afghanistan, or working at NASA to help the nation return to the Moon. He spends a lot of time with NASA engineers to understand the in-and-outs of ongoing projects since any activity happening onsite involves the Office of General Counsel. In addition to the U.S. Air Force, Renshaw has served in other legal profession roles, including as a law clerk for a Louisiana district court judge and a position in the Louisiana State Attorney General’s Office. He said working for NASA gives him the opportunity to focus on his area of expertise, while being involved in the agency’s great mission of exploration and discovery. “I love NASA, and it is good to feel part of the team and to know that you are contributing to the mission,” he said.

At the edge of Las Cruces, New Mexico, surrounded by miles of sunbaked earth, NASA’s White Sands Test Facility (WSTF) is quietly shaping the future. There is no flash, no fanfare — the self-contained facility operates as it has since 1962, humbly and in relative obscurity. Yet as New Mexico’s space industry skyrockets amid intensifying commercial spaceflight efforts across the state, WSTF feels a new urgency to connect with the community. With the facility’s latest Test and Evaluation Support Team (TEST3) contract now in its third year, Program Manager Michelle Meerscheidt is determined to make a mark. “I think it’s very important we increase our public presence,” Meerscheidt said. “We are a significant contributor to NASA’s mission and our country’s aspirations for furthering space exploration.” In September, TEST3 leadership joined forces with the City of Las Cruces to support the sixth annual Las Cruces Space Festival, a two-weekend celebration of the region’s rich relationship with the aerospace industry. The Test and Evaluation Support Team (TEST3) team — Human Resources Manager Kristina Garcia (left), Program Manager Michelle Meerscheidt, and Deputy Program Manager/Business Manager Karen Lucht — prepares to meet with visitors at the Las Cruces Space Festival Astronomy & Industry Night on Sept. 13, 2024, in Las Cruces, New Mexico. NASA/Anthony Luis Quiterio Alongside WSTF, festival director Alice Carruth is working to open a world that many believe is off limits and others don’t know exists. “Unless you’re driving over the mountains regularly and seeing the sign that says, ‘The Birthplace of the U.S. Space and Missile Program,’ you don’t tend to know what’s going on in your backyard,” Carruth said. “The whole premise of the Space Festival is to make people understand what’s going on in their community, to encourage people to think about careers in the space industry, and to inspire the next generation.” A featured speaker at the festival’s New Mexico State University Astronomy & Industry Night, Meerscheidt had the chance to do just that. “It’s fun to see a lot of young kids that are wide-eyed and excited,” Meerscheidt said. “It’s nice to be able to encourage them to pursue their dreams.” Among those wide-eyed festivalgoers was 6-year-old Camilla Medina-Bond, who was confident in her vision for the future. “I want to be an astronaut when I grow up,” she said. “I want to visit the Moon.” As for the details of her lunar mission, Medina-Bond’s plan is simple: “Just going to see what’s on it.” She has plenty of time to figure out the specifics — after all, giant leaps start with small steps. According to Meerscheidt, the aspiring astronaut has already taken the first and most critical step. “That’s what NASA is all about,” Meerscheidt said. “Explore, be inquisitive. Open your mind, open your imagination, and go for it.” Left: Camilla Medina-Bond, age 6, proudly shows off her foam stomp rocket and NASA White Sands Test Facility baseball cap during the Las Cruces Space Festival’s Astronomy & Industry Night on the New Mexico State University campus. Right: Medina-Bond immerses herself in another world as she operates a virtual reality headset. NASA/Anthony Luis Quiterio Medina-Bond’s aspiration is shared by many young dreamers. A 2024 global study by longtime NASA partner, the LEGO Group, found 77% of kids ages 4-14 want to travel to space. Carruth acknowledged that keeping the attention of today’s always-scrolling, trend-driven generation is not easy, and that children’s fascination with space often wanes as they age. “If you look at the statistics, space tends to be really cool until they get to middle school level, and then space isn’t cool anymore — not because it’s not cool, but because it then becomes inaccessible to a lot of students,” she said. Still, Carruth is prepared to navigate the challenge. “I want kids to understand that space is for everybody,” Carruth said. “I also want their parents and grandparents to understand why space is important and that this is a feasible career.” Oscar Castrejon, who attended the festival with his 12-year-old son, Oscar Jr., is on his own mission to nurture that understanding. “I’ve learned early kids need to develop their own passions, but if they say ‘hey, I like this, I’m interested in it,’ then I’ll take them to it,” Castrejon said. “If their eyes get opened, if their imagination gets sparked, you never know — you could be looking at the next NASA scientist.” Oscar Castrejon and his son Oscar Jr., age 12, stop by the White Sands TEST3 booth. Anthony Luis Quiterio WSTF TEST3 Deputy Program Manager and Business Manager Karen Lucht shares Castrejon’s philosophy, emphasizing the importance of authenticity. “Speak[ing] to who you are as a person will ultimately lead to who you will become as a professional,” she said. A remote test site, WSTF has its own ecosystem which Lucht compares to a “small city.” Among its residents are scientists and engineers, but also welders, writers, firefighters, and photographers — to name a few. “White Sands offers endless opportunities for everybody,” Lucht said. “Every career has a path here.” Lucht’s own journey illustrates the infinite potential that arises in diverse spaces like WSTF. “I came from a town of less than a thousand people, and I never dreamt that I would work for NASA,” she said. “As someone who was told many times that I would never make it to my position, I look back on my career and realize there are no restraints. You really can do anything you want to do.” For those wanting to join the ranks at WSTF, there is one important requirement: they must see themselves as stardust, a vital element in a grand cosmic plan. “We’re looking for people who have the right perspective, the desire to learn and contribute to something bigger than themselves,” Lucht said. At WSTF — a place where the stars feel close enough to touch — the sky is not the limit, it is only the beginning. View the full article

NASA astronaut and Expedition 72 Commander Suni Williams checks out the Astrobee robotic free-flyer in the Kibo laboratory module outfitted with tentacle-like arms containing gecko-like adhesive pads to demonstrate satellite capture techniques. Development of this robotic technology may increase the life span of satellites and enable the removal of space debris.NASA In this picture from Nov. 15, 2024, Astronaut Suni Williams imitates the tentacle-like arms of the Astrobee robotic free-flyer in the foreground. Astrobee robots help astronauts reduce time they spend on routine duties, leaving them to focus more on the things that only humans can do. Working autonomously or via remote control by astronauts, flight controllers or researchers on the ground, the robots are designed to complete tasks such as taking inventory, documenting experiments conducted by astronauts with their built-in cameras or working together to move cargo throughout the station. In addition, the system serves as a research platform that can be outfitted and programmed to carry out experiments in microgravity – helping us to learn more about how robotics can benefit astronauts in space.

NASA/JPL-Caltech Earth planning date: Monday, Dec. 2, 2024 Today, after a weeklong holiday break, the team was eager to take a look at Curiosity’s new workspace. After driving 51 meters (about 167 feet) alongside Texoli butte (pictured) we had a whole host of new rocks to examine, and it was one of those curiously perfect planning days where everything falls into place. Our team of geologists here on Earth was busy studying the images our Martian geologist had downlinked to Earth prior to planning, and we scheduled 1.5 hours of science activities on the first sol of this plan. An interesting and varied workspace today saw lots of instruments working together to study the rocks in-depth — teamwork really does make the dream work. To begin, we are targeting a vertical rock face called “Coronet Lake” near the rover. Coronet Lake has a cluster of nodules on show and we are getting information on the composition of these nodules with APXS and a ChemCam LIBS, as well as a close-up image with our MAHLI instrument. We also have a second MAHLI activity scheduled on a flat rock called “Excelsior Mountain.” Our observant team spotted an interesting-looking rock named “Admiration Point.” This rock may have fallen from the nearby Texoli butte, or could be a meteorite. To test these hypotheses further, we are targeting Admiration Point with a Mastcam mosaic and a ChemCam passive. ChemCam and Mastcam work together again on a target named “Olancha,” an area of rocks that could contain evidence of deformation from when the rocks first formed. Olancha will be targeted with a ChemCam long-distance RMI and a Mastcam mosaic. Mastcam is finishing off the geological observations here with mosaics of “Angels Camp,” a rock containing veins where water may have once flowed, “Bare Island Lake,” a gray rock containing interesting polygonal ridges, and a trough feature close to Coronet Lake. ChemCam is taking another look back at Gediz Vallis channel to see a transition between light- and dark-toned rocks with a long-distance RMI, and we are rounding off this plan with our standard environmental observations. As the Geology and Mineralogy theme group Keeper of the Plan for today’s planning, I made sure that this sol was packed full of science activities that the team wanted to schedule. After this busy first sol, Curiosity will be driving about 50 meters (about 164 feet), continuing to make our way out of Gediz Vallis, and we are all very excited to see what the rest of the sulfate-bearing unit has to offer us.

9 Min Read Towards Autonomous Surface Missions on Ocean Worlds Artist’s concept image of a spacecraft lander with a robot arm on the surface of Europa. Credits: NASA/JPL – Caltech Through advanced autonomy testbed programs, NASA is setting the groundwork for one of its top priorities—the search for signs of life and potentially habitable bodies in our solar system and beyond. The prime destinations for such exploration are bodies containing liquid water, such as Jupiter’s moon Europa and Saturn’s moon Enceladus. Initial missions to the surfaces of these “ocean worlds” will be robotic and require a high degree of onboard autonomy due to long Earth-communication lags and blackouts, harsh surface environments, and limited battery life. Technologies that can enable spacecraft autonomy generally fall under the umbrella of Artificial Intelligence (AI) and have been evolving rapidly in recent years. Many such technologies, including machine learning, causal reasoning, and generative AI, are being advanced at non-NASA institutions. NASA started a program in 2018 to take advantage of these advancements to enable future icy world missions. It sponsored the development of the physical Ocean Worlds Lander Autonomy Testbed (OWLAT) at NASA’s Jet Propulsion Laboratory in Southern California and the virtual Ocean Worlds Autonomy Testbed for Exploration, Research, and Simulation (OceanWATERS) at NASA’s Ames Research Center in Silicon Valley, California. NASA solicited applications for its Autonomous Robotics Research for Ocean Worlds (ARROW) program in 2020, and for the Concepts for Ocean worlds Life Detection Technology (COLDTech) program in 2021. Six research teams, based at universities and companies throughout the United States, were chosen to develop and demonstrate autonomy solutions on OWLAT and OceanWATERS. These two- to three-year projects are now complete and have addressed a wide variety of autonomy challenges faced by potential ocean world surface missions. OWLAT OWLAT is designed to simulate a spacecraft lander with a robotic arm for science operations on an ocean world body. The overall OWLAT architecture including hardware and software components is shown in Figure 1. Each of the OWLAT components is detailed below. Figure 1. The software and hardware components of the Ocean Worlds Lander Autonomy Testbed and the relationships between them. NASA/JPL – Caltech The hardware version of OWLAT (shown in Figure 2) is designed to physically simulate motions of a lander as operations are performed in a low-gravity environment using a six degrees-of-freedom (DOF) Stewart platform. A seven DOF robot arm is mounted on the lander to perform sampling and other science operations that interact with the environment. A camera mounted on a pan-and-tilt unit is used for perception. The testbed also has a suite of onboard force/torque sensors to measure motion and reaction forces as the lander interacts with the environment. Control algorithms implemented on the testbed enable it to exhibit dynamics behavior as if it were a lightweight arm on a lander operating in different gravitational environments. Figure 2. The Ocean Worlds Lander Autonomy Testbed. A scoop is mounted to the end of the testbed robot arm. NASA/JPL – Caltech The team also developed a set of tools and instruments (shown in Figure 3) to enable the performance of science operations using the testbed. These various tools can be mounted to the end of the robot arm via a quick-connect-disconnect mechanism. The testbed workspace where sampling and other science operations are conducted incorporates an environment designed to represent the scene and surface simulant material potentially found on ocean worlds. Figure 3. Tools and instruments designed to be used with the testbed. NASA/JPL – Caltech The software-only version of OWLAT models, visualizes, and provides telemetry from a high-fidelity dynamics simulator based on the Dynamics And Real-Time Simulation (DARTS) physics engine developed at JPL. It replicates the behavior of the physical testbed in response to commands and provides telemetry to the autonomy software. A visualization from the simulator is shown on Figure 4.

A scoop operation has just been completed. NASA/JPL – Caltech The autonomy software module shown at the top in Figure 1 interacts with the testbed through a Robot Operating System (ROS)-based interface to issue commands and receive telemetry. This interface is defined to be identical to the OceanWATERS interface. Commands received from the autonomy module are processed through the dispatcher/scheduler/controller module (blue box in Figure 1) and used to command either the physical hardware version of the testbed or the dynamics simulation (software version) of the testbed. Sensor information from the operation of either the software-only or physical testbed is reported back to the autonomy module using a defined telemetry interface. A safety and performance monitoring and evaluation software module (red box in Figure 1) ensures that the testbed is kept within its operating bounds. Any commands causing out of bounds behavior and anomalies are reported as faults to the autonomy software module. Figure 5. Erica Tevere (at the operator’s station) and Ashish Goel (at the robot arm) setting up the OWLAT testbed for use. NASA/JPL – Caltech OceanWATERS At the time of the OceanWATERS project’s inception, Jupiter’s moon Europa was planetary science’s first choice in searching for life. Based on ROS, OceanWATERS is a software tool that provides a visual and physical simulation of a robotic lander on the surface of Europa (see Figure 6). OceanWATERS realistically simulates Europa’s celestial sphere and sunlight, both direct and indirect. Because we don’t yet have detailed information about the surface of Europa, users can select from terrain models with a variety of surface and material properties. One of these models is a digital replication of a portion of the Atacama Desert in Chile, an area considered a potential Earth-analog for some extraterrestrial surfaces. Figure 6. Screenshot of OceanWATERS. NASA/JPL – Caltech JPL’s Europa Lander Study of 2016, a guiding document for the development of OceanWATERS, describes a planetary lander whose purpose is collecting subsurface regolith/ice samples, analyzing them with onboard science instruments, and transmitting results of the analysis to Earth. The simulated lander in OceanWATERS has an antenna mast that pans and tilts; attached to it are stereo cameras and spotlights. It has a 6 degree-of-freedom arm with two interchangeable end effectors—a grinder designed for digging trenches, and a scoop for collecting ground material. The lander is powered by a simulated non-rechargeable battery pack. Power consumption, the battery’s state, and its remaining life are regularly predicted with the Generic Software Architecture for Prognostics (GSAP) tool. To simulate degraded or broken subsystems, a variety of faults (e.g., a frozen arm joint or overheating battery) can be “injected” into the simulation by the user; some faults can also occur “naturally” as the simulation progresses, e.g., if components become over-stressed. All the operations and telemetry (data measurements) of the lander are accessible via an interface that external autonomy software modules can use to command the lander and understand its state. (OceanWATERS and OWLAT share a unified autonomy interface based on ROS.) The OceanWATERS package includes one basic autonomy module, a facility for executing plans (autonomy specifications) written in the PLan EXecution Interchange Language, or PLEXIL. PLEXIL and GSAP are both open-source software packages developed at Ames and available on GitHub, as is OceanWATERS. Mission operations that can be simulated by OceanWATERS include visually surveying the landing site, poking at the ground to determine its hardness, digging a trench, and scooping ground material that can be discarded or deposited in a sample collection bin. Communication with Earth, sample analysis, and other operations of a real lander mission, are not presently modeled in OceanWATERS except for their estimated power consumption. Figure 7 is a video of OceanWATERS running a sample mission scenario using the Atacama-based terrain model.

A scoop operation has just been completed. NASA/JPL – Caltech Because of Earth’s distance from the ocean worlds and the resulting communication lag, a planetary lander should be programmed with at least enough information to begin its mission. But there will be situation-specific challenges that will require onboard intelligence, such as deciding exactly where and how to collect samples, dealing with unexpected issues and hardware faults, and prioritizing operations based on remaining power. Results All six of the research teams funded by the ARROW and COLDTech programs used OceanWATERS to develop ocean world lander autonomy technology and three of those teams also used OWLAT. The products of these efforts were published in technical papers, and resulted in development of software that may be used or adapted for actual ocean world lander missions in the future.

Scientists find that cometary dust affects interpretation of spacecraft measurements, reopening the case for comets like 67P as potential sources of water for early Earth. Researchers have found that water on Comet 67P/Churyumov–Gerasimenko has a similar molecular signature to the water in Earth’s oceans. Contradicting some recent results, this finding reopens the case that Jupiter-family comets like 67P could have helped deliver water to Earth. Water was essential for life to form and flourish on Earth and it remains central for Earth life today. While some water likely existed in the gas and dust from which our planet materialized around 4.6 billion years ago, much of the water would have vaporized because Earth formed close to the Sun’s intense heat. How Earth ultimately became rich in liquid water has remained a source of debate for scientists. Research has shown that some of Earth’s water originated through vapor vented from volcanoes; that vapor condensed and rained down on the oceans. But scientists have found evidence that a substantial portion of our oceans came from the ice and minerals on asteroids, and possibly comets, that crashed into Earth. A wave of comet and asteroid collisions with the solar system’s inner planets 4 billion years ago would have made this possible. This image, taken by ESA’s Rosetta navigation camera, was taken from a about 53 miles from the center of Comet 67P/Churyumov-Gerasimenko on March 14, 2015. The image resolution is 24 feet per pixel and is cropped and processed to bring out the details of the comet’s activity. ESA/Rosetta/NAVCAM While the case connecting asteroid water to Earth’s is strong, the role of comets has puzzled scientists. Several measurements of Jupiter-family comets — which contain primitive material from the early solar system and are thought to have formed beyond the orbit of Saturn — showed a strong link between their water and Earth’s. This link was based on a key molecular signature scientists use to trace the origin of water across the solar system. This signature is the ratio of deuterium (D) to regular hydrogen (H) in the water of any object, and it gives scientists clues about where that object formed. Deuterium is a rare, heavier type — or isotope — of hydrogen. When compared to Earth’s water, this hydrogen ratio in comets and asteroids can reveal whether there’s a connection. Because water with deuterium is more likely to form in cold environments, there’s a higher concentration of the isotope on objects that formed far from the Sun, such as comets, than in objects that formed closer to the Sun, like asteroids. Measurements within the last couple of decades of deuterium in the water vapor of several other Jupiter-family comets showed similar levels to Earth’s water. “It was really starting to look like these comets played a major role in delivering water to Earth,” said Kathleen Mandt, planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Mandt led the research, published in Science Advances on Nov. 13, that revises the abundance of deuterium in 67P. About Kathleen Mandt But in 2014, ESA’s (European Space Agency) Rosetta mission to 67P challenged the idea that Jupiter-family comets helped fill Earth’s water reservoir. Scientists who analyzed Rosetta’s water measurements found the highest concentration of deuterium of any comet, and about three times more deuterium than there is in Earth’s oceans, which have about 1 deuterium atom for every 6,420 hydrogen atoms. “It was a big surprise and it made us rethink everything,” Mandt said. Mandt’s team decided to use an advanced statistical-computation technique to automate the laborious process of isolating deuterium-rich water in more than 16,000 Rosetta measurements. Rosetta made these measurements in the “coma” of gas and dust surrounding 67P. Mandt’s team, which included Rosetta scientists, was the first to analyze all of the European mission’s water measurements spanning the entire mission. The researchers wanted to understand what physical processes caused the variability in the hydrogen isotope ratios measured at comets. Lab studies and comet observations showed that cometary dust could affect the readings of the hydrogen ratio that scientists detect in comet vapor, which could change our understanding of where comet water comes from and how it compares to Earth’s water. What are comets made of? It’s one of the questions ESA’s Rosetta mission to comet 67P/Churyumov-Gerasimenko wanted to answer. “So I was just curious if we could find evidence for that happening at 67P,” Mandt said. “And this is just one of those very rare cases where you propose a hypothesis and actually find it happening.” Indeed, Mandt’s team found a clear connection between deuterium measurements in the coma of 67P and the amount of dust around the Rosetta spacecraft, showing that the measurements taken near the spacecraft in some parts of the coma may not be representative of the composition of a comet’s body. As a comet moves in its orbit closer to the Sun, its surface warms up, causing gas to release from the surface, including dust with bits of water ice on it. Water with deuterium sticks to dust grains more readily than regular water does, research suggests. When the ice on these dust grains is released into the coma, this effect could make the comet appear to have more deuterium than it has. Mandt and her team reported that by the time dust gets to the outer part of the coma, at least 75 miles from the comet body, it is dried out. With the deuterium-rich water gone, a spacecraft can accurately measure the amount of deuterium coming from the comet body. This finding, the paper authors say, has big implications not only for understanding comets’ role in delivering Earth’s water, but also for understanding comet observations that provide insight into the formation of the early solar system. “This means there is a great opportunity to revisit our past observations and prepare for future ones so we can better account for the dust effects,” Mandt said.

7 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) As the program manager for people, culture and equity, “people whisperer” Edward Victor Gonzales helps ensure people’s wellbeing, comfort, and safety. Name: Edward Victor Gonzales Title: Program Manager for People, Culture, and Equity Organization: Heliophysics Division, Science and Exploration Directorate (Code 670) Eddie Gonzales is the program manager for People, Culture, and Equity for the Heliophysics Division at NASA’s Goddard Space Flight Center in Greenbelt, Md.NASA What do you do and what is most interesting about your role here at Goddard? As the program manager for people, culture, and equity officer for heliophysics, I am responsible for people’s wellbeing, comfort, and safety. What is most interesting to me is the vast diversity across Goddard. How did you come to Goddard? I went to college late in life, but never graduated. After high school, I started at Mount San Antonio Community College in Walnut, California, but had to work full time when my then-girlfriend became pregnant. I started in the mail room of an international law firm, gradually working my way into director of the support staff. I worked there for 15 years, often staying overnight. I could not attend night school and there were no online learning options at the time. In 2001, Warren Christopher, who was the managing partner at the law firm and later became secretary of state in the Clinton administration, wrote me a recommendation that helped me get a job at NASA’s Jet Propulsion Laboratory in Southern California as a business administrator. Apollo 13 inspired me to want to work for NASA. After obtaining the job at NASA JPL, I took a few classes at Pasadena Community College. In 2009, I was detailed to NASA Headquarters to work in the Office of STEM Education. After two years, I returned to JPL to work on minority-serving programs. In 2014, I returned to Headquarters for a fellowship to work in the Minority University Research Educational Programs. After a year and a half, I returned to JPL to manage underserved, underrepresented undergraduate programs. In 2018, I came to Goddard to do outreach for NASA Goddard’s heliophysics division. Three years later, I became the diversity, equity, inclusion, and accessibility officer for heliophysics and now, my current role as people, culture, and equity officer. As the people, culture, and equity officer, what are your responsibilities? First, I observe. There are a lot of cues and things that happen in the world that others, including leadership, can sometimes miss. We need to be conscious of these things. We need to be respectful and kind — always. When something happens in the world that impacts a colleague, I make sure to check in with them daily. On a broader scale, when something happens in the world that affects a particular culture, I check in with that particular group. I also go to underserved, underrepresented national conferences across the country. At the American Indian Science and Engineering Society conference, I talked about employment opportunities at NASA. It was important for those students to see someone who looked like them. I am half Native American and half Latinx [a gender-neutral term for those with Latin American heritage]. “I was labeled a troublemaker. Teachers wouldn’t help me. My career counselor said I would do amazing work at a car wash and that’s what I should consider doing and not to continue my education. But I didn’t listen.” — Edward Gonzales, Diversity, Equity, Inclusion, and Accessibility Lead, Goddard Space Flight CenterNASA/Taylor Mickal In August 2024, the NASA administrator appointed you to the NASA Advisory Council. What do your duties there entail? The council has five committees: aeronautics, human exploration, science, STEM, and technology. I am a member of the science committee. My plan is to discuss the cultural role we all play at NASA. What skills do you use in speaking with underserved, underrepresented communities? I test the waters and the temperature of leadership. I am very active with the employees. I have an open-door policy. In addition, I think I am highly culturally aware overall. At conferences, I try to dress, speak, and act approachably for the students who attend. Most importantly, my cell phone is never to be seen. When interacting with someone, I am very observant of the other person’s body language overall, which helps me understand the other person better. Sometimes body language rather than words will tell you what you need to hear. My wife calls me a “people whisperer.” What does cultural awareness mean to you? Know your audience. I do not think about how I do things: I focus on how the next generation will do things. I try to speak their language. And listen, very important to listen. Typically, when I go to a national conference, students will approach me with a résumé. But at a Native American national conference, the elders may approach me with a student and a résumé. It is important to address the elder first and ask permission to speak to the student. Also, you would say that the student could bring knowledge learned at Goddard back to their reservation instead of saying that the student could leave their reservation. I also always acknowledge the tribe associated with where I am speaking. Whenever we send a team to a national conference, we send people who are culturally aware of that particular group’s culture. I also conduct cultural awareness training at Goddard. What are your hopes for Godard’s DEIA programs? I want to continue to create a pipeline of future employees that is more diverse, filled with great ideas and solutions, with a safe and welcoming environment for them. What advice do you give students? The path to NASA is not linear. You have to find your path. Eddie Gonzales looks out for colleagues wellbeing, comfort, and safety within NASA Goddard’s diverse workforce. Courtesy of Eddie Gonzales You’ve mentioned that DEIA is essentially about kindness. How do you define kindness? How do you teach it? Kindness in my humble opinion is about grace, integrity and understanding. And the willingness to learn about others and their cultures. To agree to disagree and have a polite conversation, to create that understanding. Teaching starts in the home, bad behavior, lack of understanding and racism are taught traits. We must do better and lead by example. To treat others how we want to be treated. Who are your mentors? One is Christopher Gardner, whose life was portrayed in “The Pursuit of Happyness.” I recently brought Christopher Gardner to Goddard to do a keynote speech and he even stayed with me. I met him because I saw his movie, read his book, and contacted him. I teach this lesson to students: Everyone is interested when you take the time to learn what is important to them. If there is someone you want to meet, network to try to meet them. All you have to do is ask. But first, research them so that you can talk to them about themselves and their work. If they say no, then you can move on to the next person. Gardner told me to focus on my plan A because plan B is not good. If you know that you have a plan B, then you won’t put everything you have into plan A. Tread forward as if there is nothing that you can fall back on. Another mentor is José Hernández, the first Hispanic astronaut. I proposed to my wife while staying at his condo. He told me to find my “yes” and to never give up. He applied to the astronaut program 13 times before he was finally selected. What are the next big things on your bucket list? I want to see the Northern Lights and continue to travel. I just lost 70 pounds and want to lose 20 more. I gave up meat for about six months and now eat chicken and turkey, but no longer eat red meat. I also exercise and now feel great. I want to continue to attend concerts around the country. By Elizabeth M. Jarrell NASA’s Goddard Space Flight Center, Greenbelt, Md.

Let’s begin by Inquiring into your early years, your childhood, where you were born, where you grew up, what your family was like? Do you have siblings? What did your parents do, and how young were you when you developed an interest in what has become your career? I was born in Boston. My mom lived in Vermont at the time, so it’s kind of a home state. We moved to the Washington DC area, to Alexandria, when I was about four. I have a brother whose name is Ian. He is not quite 2 years older than I am. He lives in Maine. Unfortunately, my mom, my father, and my stepfather, I’ll talk all about them, none of them are with us anymore. When my mom lived in Vermont, she was a postal carrier but was dissatisfied with that life. She had been an executive at the age of 22 In New York City, in the early 1960’s, which was very unusual at the time. She worked for the Wool Bureau. For the what bureau? The Wool Bureau? I didn’t know there was one. You’ve seen the wool label in wool clothes? The one that says “It’s Real Wool”? Well, that’s her. She actually made that happen. She’s the one who turned that into a nationwide thing. Anyway, she and my father parted ways when I was quite young, so she was a single mother and decided that she was going to take a one way trip to Virginia to throw herself into the mill there. She started a newsletter as a single parent with two little kids. I was five years old when Star Wars came out. The movie had a pretty significant effect on my life, particularly given that the main character has the same name I do. But my first inkling that I wanted to do something associated with the stars and space exploration may have actually come a little bit before that, when I was four. One day we were at a laundromat, and I was left in the back of the station wagon. Let’s remember that this was the ‘70s. My mom had some library books in the car, and there was this book on astronomy. I was young enough at the time that reading for me was still very new, and I looked at big paragraphs as scary things. I remember just looking at the pictures of the stars and thinking how wonderful it all was. And by the time I was nine years old it was all over and I wanted to be – am I really going say this to the whole world? – I wanted to be a scientist, an engineer, and an astronaut. All those things. What’s the matter with saying that to the whole world? Those are laudable goals. What I wanted to do at such an early age seems embarrassing but the fun part is I’ve actually gotten two of the three. Yes! I suppose I’ve made my peace with it all. I had figured out very early that I wanted to be in science, but my stepfather didn’t think much of it. He used to tell me things like “a physicist is a boy with a toy” and other disparaging things about my chosen vocation. We moved from Alexandria to Calvert County, Maryland, and I lived there from the age of 9 to 14. So I spent those really formative years in what I felt as a kid to be a very boring part of the world with not a lot of friends, and I was an intense geek at the time. Being a geek is OK now, being a nerd is cool, right? We’re all nerds. That wasn’t true when I was ten, and so I didn’t have the best time growing up. I was so dissatisfied with life in Calvert County that I decided I was going to get the heck out of Dodge and go to college, and so I did that at the age of 14 by going to Simon’s Rock College in Western Massachusetts. I was there for two years and then I went to the University of Maryland. But there was a little problem for me, going to college at 14: I’d never done homework. Homework wasn’t a thing for me. I didn’t care. If you’re in college and you sit down at the physics class, I was the kid that you despised because I was the kid that would come in, take the test, and ace it, having never done anything. Well, let me interrupt because you mentioned that you went to college at age 14 and I was about to ask if you were in Mensa or something? Because that’s quite an accomplishment to be able to do that. And then you said you didn’t do any homework, and that’s even more amazing. So how did that come about? Do you just have natural ability? Truth is, I was actually bored and it was kind of unhealthy. The not doing homework thing is really bad, you don’t want to do that. I got over it later, I’ll come to that, but I’ve learned lots of lessons on the way, chief of which is that brains are neither necessary nor sufficient a condition to do great things in life. It helps, but it’s neither necessary nor sufficient. Anyway, I was never in Mensa, I never bothered with Mensa. I went to one Mensa meeting and I found it impossibly boring. So yeah, I was a little bit weird. I was a little bit of a mutant in school but truth is, I was terribly bored and I only started doing better in school when they skipped me a grade and started letting me skip ahead and do other things. I started doing summer programs with the Center for Advancement of Academically Talented Youth (CTY). They sent me to Arizona State University for a summer. I went to Franklin and Marshall University in Pennsylvania the following summer. I learned Greek. After that I went to the Rock, but when I was 16, I went to the University of Maryland as a junior . . . and promptly fell apart because you can get away with what I did for only so long. Not doing homework might have worked in the introductory physics classes, but once I got into the upper division classes, that’s when reality hit and it hit hard. I was weeded out. I flunked out of physics. I did. My last semester as a physics major the first time around I had a C, a D and an F on my transcript in physics. I got a C in quantum mechanics, largely because the professor was being kind. I got a D in electricity and magnetism because that’s what I deserved, and I got an F in my lab class. My lab class! Remember that one for later, because I absolutely deserved it. I did nothing. I was horrible. I was really out of it. You have more than the average number of degrees, so I’m trying to put this all together. You’re going to walk us through how that all came about, right? How despite all this you are very well credentialed? Yeah, I can do that. So I got the C, D and the F and my stepfather, who never wanted me to be a physicist anyway, took the opportunity, since I’d been in college for 4 1/2 years, to apply a little pressure. And so he said to me: “You will graduate by the end of the year or you’re just out. We’re not paying for you anymore.” And I said (to myself), “Well, I want to graduate, so what can I graduate in?” And I thought, I can graduate in German, because in addition to physics, I had also been taking German classes. I’ve also studied Russian, Latin, Greek, Gothic and Middle High German. So I know a very little bit of a whole bunch of languages, but I love language. Language is great! Let me jump in here again because I saw that German was one of your B.A. degrees and I thought, well maybe you have German ancestry and you were trying to connect in that way with your family history? Nope. The closest my family gets to Germany is that my grandfather’s parents came from Brest-Litovsk, in what is now Belarus near the Polish border. It was invaded by Germany. They were Jews. Well, that wasn’t what I was thinking. I thought perhaps Sollitt might be a German name. But anyway, this is very impressive. Please continue. OK. Well so I flunked out and I thought, well, I can get a degree in German because I’ve been studying German. I started taking German when I was 12 or something, 11 or 12, and I kept at it. Then I did Russian for a couple of years. I did German when I transferred to University of Maryland, so I said “I can do that”. I had to take all the senior level requirements in a single semester. The chairman of the department said, “I don’t think you’re going to make it” but I did and he wasn’t very happy: I didn’t do any homework. It wasn’t a big deal to take a couple of summer classes, and then I was out. I got my degree in German, a degree that I had never wanted. I had wanted a physics degree. And I was 19, I had just turned 19. I was, in fact, a little disappointed that I didn’t get my degree at age 18, but I got it at 19, and graduated in August of 1990. That was right around the time when Saddam Hussein invaded Kuwait and we had the biggest recession since the Great Depression, and you had Harvard graduates waiting tables in Boston, that was all they could get. That was the environment into which I graduated with my unwanted degree in German with, you know, some lousy grades, although my GPA wasn’t awful. My first job was doing temp work for WFTY-TV channel 50. I did accounts receivable. I worked with a temp agency and I had to learn the job of accounts receivable by taking the test to see if I could do the job. So I thought “I don’t know how to do this, but OK, I’ll take the test.” It’s like this is how you do this and that’s how you do that, so OK, you can do receivables now! I worked for them for a couple months and then I went through the Administrative Careers with America test, a very, very brief resurrection of the Civil Service Exam. And very foolishly, where it said you can indicate where you’re willing to work, for some insane reason, I said “Los Angeles.” I’d never been there but it sounded like fun. So I put that down as a potential location, with a bunch of other places, and the only offer I got was from the Internal Revenue Service in the Los Angeles district. I read about the IRS in your bio, and I was going to ask about it, so please tell us about that experience. I was employed as a Revenue Officer. It so doesn’t fit with what you’ve been telling us about who you are. But go ahead (laughs). Let’s just say it’s been a circuitous route! I joined the IRS as a Revenue Officer in the middle of the worst recession since the Great Depression, thanking my lucky stars that I had an actual job. And it was for a rather miserable salary that I drove my mom’s car across the country to get there. A Revenue Officer is the person who knocks on doors and collects the taxes. I was hired as a GS-7. This was not a job that I liked. In fact, it was a job I viscerally hated but I did this job for nearly 4 1/2 years of my life. It taught me some really important lessons. My first lesson came on the very first day, when I attended a training session for hundreds of people (there had been a huge District-wide hire). About the first thing the first speaker said was that because we are now in the government, we must not only avoid impropriety, but the very appearance of impropriety. And that is something that I have lived by ever since. I think it’s the way you must be. I was in what they sometimes call retail government. My job was to literally go knock on doors of delinquent taxpayers and say, “Hi, you owe the government money or there are government tax returns that you haven’t filed”. I would do this driving my own car. And back in 1991, when I started, April of 1991, I was 19 years old. One taxpayer joked that he didn’t realize that the IRS was hiring from high school these days! (laughs) Yeah, I looked pretty young. I started off wearing a suit and tie and the whole bit with the badge and everything. Everybody was terrified of me. So I ditched the suit. I ditched the tie. I grew my hair out. I wore rumpled blue jeans and a rumpled shirt. I mean, I looked terrible. But everybody talked to me. I never brought out the pocket commission unless I had to. And what I found was that I ended up being really, really good at the job. I was the number two rated Revenue Officer at GS-9, the year I was rated in the district. The first-rated GS-9 Revenue Officer in LA District that year was a really nice lady named Gail, a really neat lady, a grandmother. As a Revenue Officer, my attitude was markedly different from many. I didn’t approach delinquent taxpayers as, well, delinquents. I just went there thinking that they were people with a problem that needed to get fixed. My attitude was, “Hi, I’m from the IRS, I’m here to help, and I’m serious. Let me help you”. I never, ever, ever wanted to seize things. I never seized a car. I never seized a house. Other people did. They were keen to do it but I wasn’t. I managed to avoid all that stuff by basically dealing with taxpayers like real people. And I ended up closing tons and tons and tons of cases, something like three or four times as many cases as the next person in my group, because of the way I dealt with people, treating them differently, respectfully. I got my GS-11 at the age of 22. I was the youngest GS-11 that anyone could think of, and one day one of my co-workers said that I would eventually be the Assistant Commissioner of the IRS. That idea filled me with dread… But I mean no disrespect to the hardworking Revenue Officers and others at the IRS – their job is truly thankless, but so utterly necessary. So I was doing the job, although I despised it, and then one of the best jobs in the IRS came up, which was to do the exact same job for the International District. I transferred to L’Enfant Plaza in Washington, DC and International sent me as far as eastern Canada for my first training trip. I went from Montreal to Quebec City to New Brunswick to Halifax to Prince Edward Island to Newfoundland. What a great trip. It was wonderful. I met interesting new people and it’s a very different sort of thing there because you have no enforcement authority whatsoever. You basically have to ask very nicely, but I was pretty good at that because that’s how I did my job in LA. Had people gone there to escape the oversight of the IRS? No, it’s not that they were trying to escape the long arm of the IRS, it’s just that people who live abroad still have U.S. tax obligations. They still have to pay tax on their worldwide income, whether they live in America or live outside of America. A U.S. citizen living in Canada still has to file a U.S. tax return, and they run into tax trouble, too. But you were talking about enforcement authority. You don’t have it in Canada or overseas, right? Yeah, the way it works is the revenue officer gets a case once it’s been through the automated collection system. Automated collection systems are at the big IRS centers and they’re the ones who make the phone calls, send the registered letters, and all that stuff. I’m not sure what they do today. This was 30 years ago. And once the automated collection system runs through all the stuff they do, they ship it out to revenue officers who go and knock on the doors and say “You need to talk to me”. And if they get ignored, or they don’t comply with the agreements that they make with the revenue officer, which would have to be signed off by group managers, then the Revenue Officer can take action under civil enforcement authority. Civil enforcement authority includes things like seizures and levies. You can levy wages, you can levy bank accounts, you can levy rents. You can levy any form of income, any asset. You can place a notice of federal tax lien on the person, which then attaches to all their real estate. You can actually make seizures of anything a taxpayer owns. If they have nice artwork, you can seize that, too. It’s a lot of power, and to be honest it’s pretty scary. But the reason you can do that is because the long arm of federal law exists throughout the country. When you go to a place like Canada, you’re way past federal law. You can’t seize anything or levy anything unless there’s a tax treaty with that country. And if there is, then you can do things according to the way the treaty is written. I think in Canada that enforcement was done through requests to Revenue Canada. But to first order, you have no power in Canada, so what you’re reduced to is “Let’s try to make this work”, because if you have somebody who’s been living in Canada for 40 years and doesn’t want to go back, well, then their obvious move is to renounce U.S. citizenship and tell you to go away. That’s if they never want to go back, if they don’t care about their U.S. citizenship. But most folks do. Anyway, so I did that trip and I was planning my next one, until one day, and you have to understand I went to the University of Maryland in College Park, which is literally down the road from L’Enfant Plaza. It’s like 10 miles away or so, and I was back in familiar areas. In fact, I grew up in the area when I lived in Maryland and Alexandria, so I knew the place really, really well. I was living on Capitol Hill at the time. And one day, I’m not kidding here, at International, I was literally sitting at my desk scribbling physics equations, just like the Gary Larson cartoon (The Far Side): “What’s this? Jenkins, physics equations? Do you enjoy your job here as a cartoonist?” The cartoon character Jenkins, was literally me. I was scribbling physics equations, and I looked down and I said, “Oh, God, I really have unfinished business”. So I went right up to the University of Maryland, to my old faculty advisor, a guy named Joe Redish. And I marched into his office, waved my hand, and said “Hi, Joe. How do I restart? How do I get back in? What do I do?” And he started off listing books for me on how to get ready for it, saying “Do this book, do that book”. And then he stopped, thought about it for a moment, and said “No, forget all that. Go get the Feynman Lectures on Physics and give them a read.” And I said “OK, sure”. So I got the Feynman Lectures on Physics and started reading them. They’re brilliant. I mean brilliant. I’m sure they are. But they’re not effective if you’re learning physics for the first time. It’s the last thing you want to do. It is effective if you’re doing something like what I was doing, which is getting back into the field or getting a different perspective, or as a great reference book. They’re wonderful for the right purposes, and I started reading the Feynman lectures that summer. I read them every day, all day. I read them on the subway to and from work. I read them on lunch hour. I read them on breaks. And as I read the lectures, I finally decided that I had to see about going back to school. So I went back up to the University of Maryland, walked into the registrar’s office and said “OK, I graduated a bunch of years ago and I want to come back. What’s the process?” And they said, “Well, here’s a 3×5 card. Fill it out, please.” So I filled it out and handed it back to them, and they said “You’re in!” And I said, “What? That’s it?” I just filled out a 3×5 card and then arranged for student loans. I told my mom what I was doing – I was talking to her about returning to physics before I re-enrolled. She was very, very supportive of my going back to get my physics degree. It was unfinished business. But I didn’t tell my stepfather right away because I knew he wouldn’t approve. I knew I would have to tell him eventually. My opportunity came on Father’s Day, 1995. By this time, my Mom and stepfather had divorced. But it was a crowded affair: my step-siblings were there with spouses and families, other friends were there. And I finally announced to everyone what I was going to do at the end of summer, which was leave the IRS and go back to school to get my degree in physics. Everybody in the room congratulated me, saying what a wonderful idea that was, and isn’t that great. Except my stepfather. He didn’t say a word. I knew he would not be happy about this – especially the way I ambushed him with it, in front of this huge crowd. But I knew that I absolutely had to present my decision as a fait accompli: if I had gone to him to tell him I was thinking about doing this, he would have been on me until I dropped it. At the end of the day I was the last person there and he walked up to me and he said, “I don’t know how to react to this news, that you’re going back to school. It’s as if you’ve told me that you’re quitting your successful government career to go back and study remedial English”. That’s a quote. Oh my! Yeah. So it wasn’t just a matter that he was paying for your education. He really objected to what you wanted to become through your education. Yes, that’s why he would say things like “A physicist is a boy with a toy”. He saw physicists as unserious, as non-intellectuals, which is a huge mistake. I should say. But I went back and set myself a goal. Now you remember those classes that I got the C, the D, and the F in? I registered for the same three classes and the graduate secretary told me “You can’t do that. It’s too much work. You’re going to die!” But I thought that I needed to do it and I knew if I got 3 A’s I was doing the right thing. If I got one A or less, I knew that at least I’d given it the good college try. I’d gone back and addressed this one great failure in my life, one that made my whole life feel incomplete. At least I’d done it and I could move on to other things in life now and not worry about it anymore. If I got two A’s, I didn’t know what it would mean, but if I got three A’s, I knew it was cool. So I went back and within two weeks, I was just drowning in the work. It turns out there’s a Physics Class Invariance Principle: every upper division undergraduate physics class takes 20 hours of homework per week. 20 hours, plus all the time that you’re in class. Three classes means 60 hours of work per week, more than a full-time job. But my attitude was very different in that I now had five years of work experience under my belt. I had been away from physics for five years when I went back and my attitude was that I went to Maryland in the morning and my classes were just part of my work day. I spent the rest of the day working in the library and other places at Maryland, and I went home at night, and was done, except when I started having experiments. I remember that first semester I was in the advanced undergraduate lab, the one I had got the F in, and something had changed. Suddenly, it was my favorite class! I had the exact same lab manual, and I despised it just as much the second time around. Only this time I had enough confidence to look at it and say, “This thing is horribly written. I mean, this is awful. Where does this come from? Oh, they have a source in here. Adrian Melissinos.” Anyway, it was Melissinos’ “Experiments in Modern Physics”. I went and found it in the library and started reading it and that became my textbook. Not just that book – I looked up every single source cited in all those experiment write-ups: books, monographs, reference materials. One of the sources was the book “Alpha-, Beta- and Gamma-Ray Spectroscopy” by Kai Siegbahn. I read the source material to actually learn what they were doing, and I had a blast. Oh my God, that was fun! I mean fun. One of the most fun things I did was the cosmic ray experiment. It was a timing experiment that used scintillator paddles. As a particle passed through a scintillator paddle, it would knock electrons off of the sodium iodide crystals. The electrons would be reabsorbed into the matrix, releasing light that would then be picked up by photomultiplier tubes. The four paddles were hooked up to some simple logic boards to generate a coincidence circuit, where a coincidence gate would be opened by triggering the first paddle. You’d get simple yes/no signals from subsequent paddles, and if you got four yesses (energy deposited in each of the paddles within the timing gate duration), you’d have a coincidence, and add that particle to your measured cosmic ray flux. You learn something about the energies of the cosmic rays by varying the shielding between pairs of scintillator paddles. More shielding means you get fewer yesses in the paddles below the shielding. And I thought, OK, that’s cool. What about trying a direct measurement of the energies of these things? I went to the professor, Phillip Roos, who was a member of the board of directors of the Jefferson Laboratory (the Thomas Jefferson National Accelerator Facility, a high-energy electron-positron collider in Virginia). He loaned me a very thick scintillator and I started doing actual spectroscopy with this thing. And I learned all about the Landau curve. Basically, it’s what happens when a high energy particle penetrates a thin layer. How much energy does it give up? It’s a quasi-stochastic process, but the distribution of energies deposited in the layer by particles from a monoenergetic beam is something called the Landau Curve. It is incredibly complicated and way past the purview of an undergraduate class to try to model or do anything with. But I did my best. And so I put that together as one of my experiments for the class and I just absolutely loved it. I just loved it. In quantum mechanics, I absolutely died. Completely. And I realized that I had major problems. I even had a call with my mom, telling her “I don’t know if I’m doing the right thing”. Looking for a way forward, I realized I couldn’t do it myself. I needed to join a study group, so I started looking around, asking folks, “Can I join your study group?” And I kept getting the cold shoulder. What I didn’t realize was that they didn’t have study groups. And finally, at one point I just said OK, nobody wants me to join their study group, not realizing they didn’t exist, and I decided to do a study group of my own. I started inviting people, and they were eager to join. Quantum mechanics is still the thing I know best from that period, because I ended up teaching it. I had about five or six people, mostly from a student group called Students for the Exploration and Development of Space (SEDS). It was the undergraduate space exploration gang. And I ended up teaching them quantum mechanics. It was wonderful, you’re jumping into it and the book is throwing all the math at you up front, like it’s hitting you with a baseball bat. And at the same time, I took E&M as well. In that class I did actually fall in with a couple of guys and the three of us became an established study group for that and kept it going for a number of classes. But it ended up being 20 hours a week per class, 60 hours easy. I was in the lab at times until midnight or later, as well as on weekends, and I ended up getting 3 A’s! So in the end, I did it right. So I stuck around. I could have finished my degree in a year but I had a strategy: I wanted to get into a good grad school and I figured that no grad school would touch me with those C, D, & F grades on my transcript. Remember those? I think a C or a D in one of my math classes is really bad, but I knew no one would touch me if I didn’t have really, really good follow up grades, so I needed to take two years, not one. So that’s what I did and I also knew that I needed a really good recommendation to get into a good grad school, so I signed up with something that fell out of the cosmic ray work. Originally, I didn’t understand what I was getting with the energy measurements from the thick scintillator. I didn’t realize yet that I was looking at a Landau curve. And Dr. Roos said. “Hey, go talk to Dr. Jordan Goodman, who is one of our younger professors. He does cosmic rays.” So I talked to Dr. Goodman, and he literally laughed me out of his office. He was brutal. He was in particle astrophysics. He said I was doing things wrong. He told me what I was doing wrong. He said I had put my big thick simulator between the four paddles. There’s two paddles above, two paddles below. I put the simulator in between them. He wanted me to put the simulator at the bottom. And so having been chased out of his office like a scolded dog, I went back to my experiment. I played with what I was doing. I got the Landau curve. That’s how I learned about the Landau curve. And I actually went and studied up on it. I found out by looking through things. And then I went back. I took Kai Siegbahn’s book “Alpha-, Beta- and Gamma-Ray Spectroscopy”, a really good book, and I got my new results. I tried it his way and I tried it my way and my way worked better, and I marched right back into his office and said “OK, I did this and I did this and I did this and I get this, this is the Landau curve. It looks like this crazy equation, but here’s where it’s coming from with the physics. I tried it your way and I tried it my way and my way worked better. He didn’t laugh and I ended up working for him. He sent me first to New Mexico to work on the MILAGRO detector. This was a Cherenkov detector. Cherenkov detectors, they’re water, ultra-pure water, and particles go through them at very, very high speed, faster than the speed of light in water, and they are giving off shock waves, just like supersonic shockwaves. Only this is light. It’s called Cherenkov radiation. It’s blue. I forget exactly why the physics makes it blue, but it does, and there’s an opening angle cone, it’s the same physics, just with light instead of sound, and you pick those up with photomultiplier, tubes set in the water. It’s actually quite similar to the work with scintillators, but you’re putting photomultiplier tubes in the water instead of on a scintillator. Same kind of deal. Different physics makes the light, but from the photomultiplier tube out, it’s the same thing. So I had a one heck of an adventure one summer in New Mexico. One of the other two guys in my study group, named Aaron Eichelberger, went out with me. And we both worked on the detector over the summer. That was good times. Up at 10,000 feet, I was in the best shape I’ve ever been in my life. I’ll bet. Just about. We were building. We had these sand filled PVC pipes at 100 pounds a pop and I would pick one up and take it into the detector, you know? I was basically doing grunt construction work. I helped tear down the Cygnus detector too, which was another scintillation detector. The following winter Jordan Goodman sent me to the Super-K detector in Japan. He also wrote my recommendation letters for grad school. And my plan, long story short, paid off. I was accepted by the University of Colorado at Boulder’s APS Department, which is Atmospheric and Planetary Sciences. That’s a very, very good program and I was going to go there until I was accepted by Caltech. Caltech is where I always wanted to go. I had applied to Caltech for transfer when I was fifteen and they said no, but for grad school they said yes. I figured they might because I was weird and Caltech does weird. Caltech is weird. (laughs) I applied to Berkeley, too, mostly for my stepfather because he was a Berkeley man, but I figured Berkeley wouldn’t touch me with a 10 foot pole, and they didn’t. They said: “No, thank you!” So I went to Tech and I ended up working in cosmic rays. I worked for Ed Stone, who was the director of JPL, who went from managing 5,000 people at JPL when he retired to managing me! (smiles). That was kind of an intense experience, but he taught me wonderful, wonderful things. I started off as an anomalous cosmic ray physicist. That’s what I wanted to do, looking for the termination shock, but Voyager didn’t get there during my time in graduate school. I remember spending a long six months trying to figure out, can I do this? I did my candidacy exam and advanced to candidacy based on anomalous cosmic rays, but then realized I didn’t have enough for a thesis. That was a low point. I was depressed but one day I came into my office and there on my chair was a stack of papers about solar particles. And I said “OK, I’m a solar particle physicist now!” So I ended up doing a thesis on solar particles. And I found, you know, cosmic rays, solar particles, the guy who did the thesis before me put into his acknowledgements that “it is often a dry field.” That’s a hard thing. Most folks who get cosmic ray, space cosmic ray degrees, end up elsewhere, and I did too. I was in grad school. I graduated. I did my thing and actually my defense was fun. I didn’t want my defense to last forever, so I wanted to schedule it for 11:00 o’clock, right before lunch, because noon rolls around and everybody at Caltech goes to lunch at noon, the whole campus, everyone turns out for lunch. It’s the only time you ever see people on campus, noon. And I figured that my thesis wasn’t nearly as important to my thesis committee as lunch, so I figured they would give me an easy pass. So I proposed this time to my advisor, and he said no. He rescheduled it for, I think, 8:00 o’clock in the morning or something horrible like that, 9:00 o’clock, and I gave my talk, I did my thing. I even had one of the guys there who loves to kill grad students. We were required to have at least one of those people on our committee and I had them both times (candidacy and defense). They just love to murder the ill-prepared grad student. So I gave my talk, it was like forty, fifty minutes, and I solicited questions. And one of them said, “Well, you’ve got a typo on page 2”. And the other one said “It’s kind of thin, it’s only 125 pages. Did you do more than that? And I said, “Well, I did. I worked on anomalous cosmic rays, but I didn’t think that was worthy of going into this thesis because it’s different. And they said “OK”. They had essentially no questions for me. Ed looked at me and said, “I’ve been doing this for 35 years and I’ve never seen that!” So apparently I did pretty well. You know, you would have ace’d a PhD in behavioral psychology! There are so many ways that you did things, interacting with other human beings, understanding their motivations and what impels them, developing your own strategies for success. Well, you know, I learned a lot of that in the IRS. There you’re walking into a situation which is absolutely beyond question, adversarial. Yeah, you changed the job that you had there. The way they set you up to go out with a suit and tie on, and then you found that what works better is to be human and meet people at their level. And your results bore that out. Yep. they did. But that was you. It was almost reverse psychology that you worked on people. Instead of coming in with a hammer, you came in with a handshake, saying “What can I do to help you comply?” Yeah, I had people actually thank me for coming into their lives. Because my assumption, my feeling, is there’s this willful naivete, which I call honor. But one mustn’t misunderstand. It is a naivete about the world and the people in it, and I decide to be that way. I decide that people have good intentions, generally speaking, but not all of them. Clearly there’s some bad apples out there. There’s no question that if you do life this way you’re going to get hurt. It does happen. But you live better. You just live better. I think that’s a good philosophy. Now let me direct this a bit because we’ve already gone longer than most of these interviews go, but your story is fascinating. I’ve pretty much thrown away the interview questions because you’re telling about yourself and that’s what we wanted you to do. It’s just a wonderful story. It’s been different from the other ones that we’ve done and probably better for that, so I’m not concerned, but there are a couple of things we want to touch on, get your thoughts on, and then when we get this back to you on paper, if there’s more you want to say about this, or if you want to talk about something else, you can conduct your own interview and just write the way you want it. I don’t think it matters how long it is. It’ll probably be one of the longer ones, but I think when we post it, it can go down as far as there are words and people are willing to hang in there and read it. It’s a fascinating read, that’s for sure. But one of the things we like to ask is, OK, you’ve had a very, as you said “circuitous” route to getting your job, but you’re good at it, and it’s what you apparently love, because you went back to it twice, into physics, and now planetary physics. But if you weren’t a NASA research scientist, or a physicist, what would your dream job be? Well, I mean, the dream job for me, I have to admit, as I told you: scientist, engineer, astronaut. OK, you did answer that already. The neat part is, when I got out of grad school, I went to work for Northrop Grumman as a system engineer and I learned about system engineering. So I’ve actually ticked off two of the three. Yes, you have. Let me give you a slightly different and slightly better answer than that, which is I have had a cataract in my left eye, starting from when I was very, very young, so I was unable to pursue what I otherwise might have done, which is that I would have gone after being a pilot in the Air Force or the Navy. That’s the other thing I wanted to do. I love to fly. You’ve told us a lot about your education and about your work, but what do you do for fun? Well, I have a family, first off. Tell us about your family. We want to know about that, too. My wife, Marie, actually has a PhD in developmental psychology from Cornell, which she completed in my living room at Caltech. Really? Because I sat her down and fed her for a summer, and allowed her to do nothing but her thesis for the summer. I feel very proud of that. But her real passion is books; she’s a librarian. So I actually put her through library school too. She’s now a librarian over at San Jose City Library and loving it, I hope. At least I think she is. We have two children, a daughter, Lynn, who is 17 and a senior in high school. And she loves cats. We have a cat, it’s a long story. Our son Tristan is 14. He just started high school. He likes building stuff. I need to get him focused on his math, but he likes building things and that’s very cool. I want him to keep doing that. He can be wildly creative. Mostly he likes to work in paper, but now I’m trying to get him to work in other things. So that’s the family. We like to travel. We like to go places, just go visit stuff, you know. I’m trying to sell them on California too, because I did uproot them from South Carolina, which they had known basically their whole lives, and it’s been quite a readjustment. But in terms of other things I like to do, well there’s the standard stuff, you know, music and various things and reading. And in fact, if you’re wondering about what kind of books I like to read the most, it used to be science fiction. I like science fiction, but I‘ve got to be honest: the latest thing I’m into is primary sources. That’s actually always been true and I’m going to sound really horrible here, but I’m the kind of guy who reads the original Marco Polo. I’ve read Voltaire, Giraldus Cambrensis, also called Gerald of Wales, who wrote in the 13th century. I read the English translations. Sometimes I try to read the others, but it’s difficult. My ancient languages aren’t that good. I kind of wish they were. I’d like them to be, but they’re not. I like reading histories as well, and biography and things like that. I’ve been doing a lot of that lately. I’ve been trying to learn a lot about the history of the Spanish-American War period and the First World War. It’s very, very interesting. Other things I do: I’m a private pilot and in fact, I am in the middle of a long odyssey to pick up an airplane and bring it home. It’s my own. It’s called a Varga, and it’s a tandem two-seat training aircraft. It’s got a glass canopy and a low wing, and looks like a little fighter airplane from the ‘40s or something. I’m halfway through flying it from Minnesota to here. I had a few problems along the way, and had to stop in Amarillo for repairs. Hopefully I’ll be finishing the trip soon. So in the near future I’m going to have a blast. I like driving, too. I have a Jeep. It’s a funky diesel from Japan. I also like to hike, though I haven’t done a whole lot of hiking lately. You mentioned music. Do you play an instrument? No, no, not really. I tried. I failed. Where does your taste run in music, then? Oh, to all kinds of things. I grew up in the ‘70s and the ‘80s and you know, I was poisoned by Sting, The Police, Genesis, stuff like that. But I’m a big fan of folk music. American folk music, but also English folk music and Scottish and Irish folk music as well. Even Welsh. That’s really great stuff actually. Breton and other things like that. I’m a big fan of Newfoundland folk music, I discovered that in Newfoundland on my trip for the IRS. So I do a lot of that sort of thing and lately in the last 15 years or so, I’ve actually become a devotee of some forms of country music, so shoot me! No, no, no, it’s all good stuff. I mean, music is music. It’s good stuff. I like classical music too. I’m a big fan of all sorts of things classical. I used to love Baroque music exclusively, but my tastes have become a little more sophisticated since then. I like all sorts of things now. That’s very eclectic and I appreciate that. I think about when people ask me what my favorite color is and I’ve thought, how can you answer a question like that? The colors are all in context, they’re all beautiful. They’re all wonderful. We would miss any one of them if they weren’t there. On the kids, by the way, our daughter is a violist and our son’s a cellist, so they like music too. My kids at Badwater Basin, Death Valley. I gave a talk at the Dark Sky Festival, February 2024 Yes, you mentioned you have an airplane and a Jeep. Are you interested in mechanics at all? I know Jeeps tend to have a good amount of repairs. I don’t know if pilots fix their own planes, how does that end up going? Luke’s Varga airplane parked at Reid-Hillview airport after he flew it to California from Minnesota. Luke flying solo. And with his daughter. You don’t do a lot of fixing of your plane as a pilot (unless you really want to). The Jeep I have is a diesel from Japan, so it’s incredibly reliable. I’ve never breaks. But I have to admit, when I was in grad school, I desperately wanted to get involved in lab work. I went downstairs one day and I talked to the post doc who was leading a balloon flight project for high energy cosmic rays. And I said, “I want to get into lab work”. And she said, “Great! I’m so glad you want to get into lab work. Here, analyze this data.” And I got pegged as a theorist, my whole career. But that all changed after I left grad school and I started working with JPL. Northrup Grumman sent me to work at JPL two days a week for a good long time, and I learned about lab work. I learned all sorts of fun things. I learned about experiment design and I started doing it. I started building things and I have really found the joy of building an experiment and making it work. I adore it. I love it. I’m doing it on a project called SPARTA, right now. I’ve actually had to build it, build the experiment, a couple of times. The last time was for Zero-G flight, and when I showed up at the airport, the PI was there and he handed me a bag. That’s not hyperbole. He handed me a bag of broken parts that I had never seen and said “Here’s your experiment. And it has to be ready in 40 hours. And we don’t know how to do it.” So I had to figure it out and make it work, in 40 hours. From nothing. And I did. And we flew and we got data and I was very, very proud of that. Aboard Zero-G light for SPARTA You are absolutely one of the most fascinating people that I have ever had to privilege of talking with and knowing. I’m just incredulous at your story. It’s wonderful. It’ll play very well in our series, but it really belongs in a book or a biography or something like that. A lot of people could learn from it. Well, I have to tell you, coming here to Ames is in many ways absolutely a culmination. I giggle when I come to work, are you kidding me? And I tell everybody this, I’m a NASA fan boy. And I will put the disclaimer out first that I understand that NASA is a large, dysfunctional government agency that is going to break your heart. OK, it’s going to do it because that’s what big dysfunctional government agencies do. It’s going to enrage. It’s going to make you frustrated. You’re going to want to kill it. But I love it. I am a massive fan. Yes, you’re absolutely right. But it needs people like you. Yeah, but when I come in, I like coming into Ames because I just giggle! I can’t believe I’m here. I can’t believe that I’m a bona fide NASA rocket scientist! After all this time, I get to finally do it. I wanted to be a scientist, you know. And the other thing that comes to me is I can’t believe they took me. I had the exact same reaction in grad school at Caltech. And by the way, so did everybody else. I went and talked to lots of graduate students at Caltech and they all said the same thing: “I can’t believe they took me”. It wasn’t until I got to the NSF that I learned about imposter syndrome. Right. It’s like, whoa, that’s my problem: imposter syndrome. Everybody has it. I’m hesitant to bring this to a close, but we do need to and I need to explain a couple of things to you. Sure. One of them is that when we finally get this into a transcript narrative that you’re comfortable with, then we would like to include pictures from your life, from yourself, from your family, not just of your work, but things we’ve talked about. Anything that would go along with the narrative, You can think about that because there will be a few weeks, but we’d like you to provide a few pictures. If you’ve seen some of the other interviews you’ve seen the pictures. Pictures go a long way to illustrate and bring to life what you’ve talked about, helping people understand who you are. And we also like to ask if you have a favorite quote, something we might see on your desk or wall, something that motivates you or that you find particularly meaningful. You’ve already said one earlier in this conversation that comes from you that I really liked. Which one was that? It was toward the beginning, you were talking about the people who do great things. It was something like “brains are neither necessary nor sufficient to do great things”. They’re not. Now you’ve got to work hard. You got to work hard. Yeah. That resonated with me when I heard it. That’s a good quote. For me the difference was that I actually sorted myself out and actually started figuring out how to do the work and that made all the difference. You don’t need genius to succeed. And genius is not enough to succeed. I like that. And if there’s something that has been sort of a lodestar for you, maybe from Feynman or from someone along the line that you just thought, “Oh, I like that, that’s motivating” or something, that helps people understand who you are, what motivates or impels your life toward who you are today. It’s just an opportunity and you can think about it and put it in later. It’s not a problem. It’s just something that helps tell your story. I don’t know. I used to put a quote, I thought it was from Alcuin, an 8th century philosopher, a neat guy, he taught Charlamagne, and was a student of Venerable Bede. Anyway, from early medieval history and I have found it to be a very significant quote. It may not be eloquent, but it is (he quotes it in Latin: “Claudit iter bellis, qui portam pandit in Astris”): “That road does not lead toward war, whose gate lies open to the stars”. That’s profound. It is and what’s particularly profound about it is that this is coming out of the medieval Christian period and you would have thought it would be “heavens”, as in “heaven”. But it’s not. It’s astris, stars, and what that means to me is that exploration is where it’s at. Exploration keeps us away from the darker aspects of our being. We can avoid war by exploring. If war expresses the worst parts of humanity, exploration expresses the best parts of humanity. OK. And first of all, I think that’s the first quote we’ve gotten in spoken Latin. That was Latin you were speaking? Yes, it was. I thought so. OK. But this is something that brings us together in a cooperative venture. The explorations that we’ve done that have included cooperation with other nations have certainly been among the few things in our world that have brought nations together. There are a lot of things that push nations apart and cause them to go to war but this is something that brings them together in a cooperative venture that transcends earth, really. Absolutely. That’s a wonderful quote. It is particularly true of what we do here at NASA. Yes. I mean exploration. Ask me sometime about the defense value of ISS. Because the ISS is probably one of the most important national security things we’ve ever done and for reasons that are completely out of left field. Yes, absolutely. You’re right. And we’ve seen that recently with the whole thing that’s going on over in the Ukraine. Yeah. They pulled out of a lot of things, but they didn’t pull out of the space station. They didn’t. Not yet. Anyway, this has been an absolutely fascinating interview so let’s put a close to it and then we’ll see what we’ve got when it comes out on paper. And then you can do with it what you want. And no matter what we do, this will have a limited audience on our website, but I hope you’ll give some thought to eventually writing an autobiography. It’s a story well worth hearing. I would buy it and read it, I’ll tell you that. I was actually told to do that 20 years ago. And I thought, “What?” Well, you’re still young! Alright. Thank you, Luke. This has been a joy, a delight and we’ll get back to you when we have something, and I think this will make a wonderful addition to our interview series. I’m glad to help, alright. OK. And yes, anything else? Any other questions or anything? No, that’s all I got for now. Thank you. Take care, gentlemen.

The rover used its Mast Camera (Mastcam) to capture the image on sol 4369 – Martian day 4,369 of the Mars Science Laboratory mission – on Nov. 20, 2024 at 04:29:24 UTC. NASA/JPL-Caltech/MSSS Earth planning date: Monday, Nov. 25, 2024 Today we planned a mammoth seven-sol plan, to cover the U.S. Thanksgiving holiday period. Unfortunately, our weekend drive ended a little early and we didn’t receive all of our needed confirmation imagery. At 7 feet high and weighing about 2,000 pounds, the rover itself is as big as a large car (check out this page, with a 3D interactive model of the rover, and more details about its dimensions). However, the contact science instruments are at the end of the arm, which stretches for another 7 feet (2.1 meters) when fully extended — for example, when reaching for a target in the workspace. We really need those confirmation images to be sure that all six wheels are firmly planted on the ground before taking out the arm to do contact science — no one wants our rover to be all wibbly-wobbly, like a giant tower of Thanksgiving jello! So, no APXS or MAHLI this Thanksgiving; but we have so many other activities, it’s a very stuffed plan. Mastcam has more than five hours of activity across the plan. A planned mosaic of Texoli butte and surrounding area grew so large, it was split into two distinct activities of a 50×4 mosaic (four rows of 50 images) and a 50×1 mosaic. This dusty workspace has so many interesting features, with abundant spherical nodular or concretionary features (typically less than 2 centimeters, or 0.79 inches, in diameter), thin dark-toned layers interbedded with the more dominant paler-colored bedrock and some well-preserved polygonal ridges. Mastcam will image the workspace in a 4×4 mosaic, giving us a lot more information on nodule size and distribution, and on the relative stratigraphic placement of the darker-toned layers, polygonal raised ridges (like those in the accompanying image), and nodules. A second (4×3) mosaic to the right of the rover at “Saurian Crest” looks at variations in bedding layers. ChemCam will take LIBS measurements on some of the larger nodular areas at “Golden Bear Lake” and “Frying Pan Lake” and a further measurement on part of a polygonal ridge at “Caltech Peak.” The environmental theme group (ENV) will run activities across the plan too. The REMS instrument will acquire data right across the week. A series of single frame change detection Mastcam images on two areas of converging ripples (“Ostrander Hut”) are planned — these will be taken on three different sols to look for changes in the sediment pattern, which could give information on wind movement, strength, and direction. Mastcam will take three “tau” measurements, imaging the sky to quantify the amount of dust in the atmosphere, and Navcam will acquire dust-devil movies and suprahorizon movies on three separate sols. Our drive on the sixth day of the plan will set us in a new workspace. As one of the NASA engineers said today, we will be looking at “rocks billions of years old, on another planet that has never been looked at before by human eyes” — we have a lot to be grateful for this Thanksgiving holiday!
