NASA Ames’ Contributions to OSIRIS-REx

by Gianine Figliozzi

Extraterrestrial rocks and dust – material scooped up from an asteroid – were delivered to Earth on Sept. 24, 2023. A safe landing in the Utah desert for the spacecraft carrying this bounty marked the end of a seven-year journey for NASA’s OSIRIS-REx – short for the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer – and the start of two intensive years of sample analysis activities for mission scientists on Earth. 

Over the coming decades, scientists around the world will study the rocks and dust collected from the asteroid Bennu to learn about the formation of the solar system and the delivery of organic molecules to early Earth.

Bennu is also one of the most potentially hazardous asteroids for Earth impact, although the chances of impact in the 22nd century are only one in 1,750. Understanding the physical and chemical properties of asteroids like Bennu will be critical, should humanity need to mitigate impact hazards in the future.

Teams at NASA Ames have played critical roles in preparing the mission for success and will continue to work on the OSIRIS-REx samples once they arrive. They helped design ways for the mission to collect high-quality samples, preserve them in pristine form, and develop a plan for the scientific community to study the essentially irreplaceable asteroid material. Ames experts also advised the mission on its thermal protection system – notably the heat shield that will protect the sample return capsule from the blistering heat of passing through Earth’s atmosphere.

Read on for more details of Ames’ contributions to OSIRIS-REx.

Preparing for an Asteroid Sample: From Canister to Curation 

Ames researcher Scott Sandford has been involved with OSIRIS-REx since the earliest days of the mission. A major area of his work was in the design and testing of the air filter system on the sample return canister that has housed the precious asteroid material during its journey to Earth and will protect it from contamination when it lands on the surface. 

The canister’s air filter was tested in Sandford’s lab before the mission launched. It will keep earthly contaminants out of the sample and, if the asteroid material is releasing any gases, the filter will trap them. If that’s happening, scientists could identify some components of Bennu. Sandford will coordinate a group of scientists in labs around the world to analyze the air filter after its return to Earth.

Sandford also leads the effort to analyze many components of the sample return capsule, both to assess potential sources of contamination in the samples and to assess the performance of the capsule.

Sandford’s sample curation work helped plan how the unique material from Bennu will be used. Three-quarters of it will be made available for study over the coming decades, while the remaining 25% may be distributed to researchers in efficient ways that let them address the mission’s scientific questions.

Withstanding the Heat of Earth Entry

The heat shield thermal protection system (TPS) is made of a material developed at Ames: phenolic-impregnated carbon ablator (PICA). PICA was first flown on NASA’s Stardust mission, which also delivered extraterrestrial material to Earth – from a comet.

The Stardust sample return capsule was nearly identical to that of OSIRIS-REx, so the latter mission was able to use the Earth-entry, descent, and landing systems successfully demonstrated by the earlier mission. Reusing many features of the Stardust capsule design, adjusted for the specific needs of the mission to Bennu, allowed OSIRIS-REx to reduce costs and the thermal protection team to leverage what they had learned from Stardust.

They then worked with mission partner Lockheed Martin Space – who designed and built the spacecraft and capsule – to integrate the air filter and PICA elements onto the mission. 

Ames helped qualify the PICA to withstand the extremely high temperatures experienced upon entering Earth’s atmosphere. They provided guidance to the mission on the PICA thickness needed to protect the samples and tested the heat shield material under simulated atmospheric re-entry conditions in Ames’ arc jet facilities to confirm thermal protection performance for the design. Ames experts in computational fluid dynamics supplied analysis that validated the aerothermal environments used in those tests. 

Soon after the spacecraft returns, members of Ames’ thermal protection team also plan to laser-scan the OSIRIS-REx heat shield in coordination with colleagues at NASA’s Johnson Space Center in Houston, Lockheed Martin, or both. What they learn about PICA’s performance, relative to predictions, can support future missions such as Mars Sample Return, that will return samples collected by NASA’s Mars Perseverance rover to Earth in the future.

Asteroid Sample Science 

When the OSIRIS-REx capsule lands in the Utah desert, researcher Scott Sandford will be on the ground to help retrieve it. The chances of contaminants like soil and water entering the sample canister inside are extremely low. But, to be absolutely certain no one accidentally studies terrestrial materials thinking they are samples from Bennu, he will help collect samples from the environment where the capsule lands, for comparison with the asteroid material. 

Later, Sandford will perform scientific studies of the Bennu samples themselves. His study will focus on two areas. He’ll assess what, if any, spacecraft-related contaminants got into the samples, such as material coming off the heat shield as it ablated, or “burned off,” during atmospheric entry. Sandford will also probe the samples for any organic compounds. Scientists estimate that Bennu is 4.5 billion years old and contains well-preserved materials, including complex organics, from the early solar system. Finding organics could tell us something about what roles materials of the early solar system may have played in delivering organic “ingredients of life” to the early Earth.

The techniques Sandford uses will allow him to search for compounds inside the Bennu samples. At Ames he’ll use infrared microspectroscopy to detect various kinds of organics in the samples that contain carbon, hydrogen, nitrogen, and oxygen. He will also work with colleagues to study samples using the Advanced Light Source facility, a specialized particle accelerator that generates bright beams of X-ray light for scientific research, located at Lawrence Berkeley National Laboratory in Berkeley, California. Both techniques provide information about the kinds of chemical bonds present in the samples’ organic compounds. 

HORIS: A Study of Atmospheric Entry

NASA’s Langley Research Center in Hampton, Virginia, will manage an experiment taking advantage of the OSIRIS-REx sample arrival to study characteristics of re-entry through an atmosphere. 

Four aircraft and teams at three ground sites will track the capsule’s trajectory on its way to the surface, using imaging and spectroscopy instruments. Data from the project, called Hypervelocity OSIRIS-REx Reentry Imaging & Spectroscopy (HORIS), will be used to validate and develop planetary entry models.

NASA’s Earth Science Project Office (ESPO), based at Ames, will provide operational and shipping support to two international ground teams by setting up work sites at three different locations in northern Nevada.  

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator. The university leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft and provides flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. Curation for OSIRIS-REx, including processing the sample when it arrives on Earth, will take place at NASA’s Johnson Space Center in Houston. International partnerships on this mission include the OSIRIS-REx Laser Altimeter instrument from CSA (the Canadian Space Agency) and asteroid sample science collaboration with JAXA’s (the Japan Aerospace Exploration Agency) Hayabusa2 mission. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.

Face of NASA: Protocol Officer Carolina Rudisel

“I never would have imagined myself here at NASA. I’m an immigrant. I was originally a Mexican citizen. I was actually born in Mexico, but my parents came over to the U.S. [and I got my green card] when I was two. … My parents originally came over on a worker visa, and so we were migrant workers [when I was] growing up.

Carolina Rudisel
“… I try to tell folks that it’s not where you started. It’s not the mistakes you’ve made. It’s what you do with it, and you can make that change not only for yourself but [also] so others can see you making the change and [know] that anything is possible.” — Carolina Rudisel, Protocol Officer, NASA’s Ames Research Center

“… It was a rough upbringing, and so I knew what my life held for me if I stayed in [my] small town. I knew that I would be stuck, as even now, looking back, some of the people I knew are still stuck. So, I decided that I would join the military because I knew that, for myself, I needed to make a radical change. And so I joined the military, and my life completely turned around. … That’s where I met my husband. We’ve been together 32 years; we’ve been married for 29 years.

“… [Before I joined] the military … I was on the wrong end of the law. I was literally standing in front of a judge who had my fate in their hands. … My recruiter happened to be at my hearing, and so we did a plea bargain and I was let off with a fine. But my life could have been completely different. So I knew the radical change was absolutely necessary for my life.

“… Fast forward: [I] joined the military, got out, and ended up spending most of the time overseas. I lived in Japan — as a matter of fact, both our kids together were born in Japan. [We] lived in Japan, Russia, Sri Lanka, Belgium, and our last post was London.

“… I worked for the Defense Attaché Office, and my co-worker was in the Navy and she was like, ‘There’s a job in NASA in Northern California! You’re from California, right? … You should apply.’ And I [thought], ‘There is no way.’ You know, I’m a businessperson, my background is in business. I was a finance budget analyst. And so, I was like, ‘There’s no way.’ She [said], ‘You should apply. Apply, apply, apply! The worst thing they could say is no.’ And I’m like, ‘You know what? You’re right.’ I applied, came to NASA, [and] actually started off here as the secretary for the center director.

Clues to Psyche Asteroid’s Metallic Nature Found in SOFIA Data

When the asteroid Psyche has its first close-up with a NASA spacecraft, scientists hypothesize they will find a metal-rich asteroid. It could be part or all of the iron-rich interior of a planetesimal, an early planetary building block, that was stripped of its outer rocky shell as it repeatedly collided with other large bodies during the early formation of the solar system.

New research from scientists at NASA’s Ames Research Center in California’s Silicon Valley suggests that is exactly what the agency’s Psyche mission will find.

Led by Anicia Arredondo, the paper’s first author and a postdoctoral researcher at the Southwest Research Institute in San Antonio, Texas, and Maggie McAdam, Ames research scientist and principal investigator, the team observed Psyche in Feb. 2022 using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA). The now-retired observatory was a Boeing 747SP aircraft modified to carry a reflecting telescope. As a flying telescope, SOFIA collected data that was not affected by Earth’s lower atmosphere and made observations from all over the world, including over the oceans.

For the first time, SOFIA was able to gather data from every part of Psyche’s surface. It also allowed the team to collect data about the materials that make up Psyche’s surface – information that could not be gathered from ground-based telescopes.

The Ames team studied the way different wavelengths of light bounce off Psyche. Researchers used a mid-infrared camera, which detects wavelengths in the middle of the electromagnetic spectrum, to observe the asteroid. They measured its emissivity(the amount of energy it radiates) and porosity (how many tiny holes or spaces an object has). Both characteristics can provide clues about the materials that make up an object.

The team observed that Psyche’s emissivity data was mostly flat, meaning there were no spikes or other notable features in its spectra – that is, a chart or a graph that shows the intensity of light the asteroid emits over a range of energies. Similarly flat spectra have been found in laboratory settings when mid-infrared instruments are used on metal objects. This led the researchers to conclude that Psyche is likely a metallic body.

Notably, the team did not observe a spectral feature called the 10-micron plateau, which typically indicates a “fluffy” surface, like lunar regolith. Previous studies of Psyche had observed this feature, which suggests there may be differences between the surface at Psyche’s north pole, which was facing the Earth at the time of the Ames team’s study, and the surface at its south pole, which was the focus of previous studies. The team also proposed that the south pole regolith observed by other researchers could have been ejected from a collision elsewhere on Psyche’s surface. This idea is supported by past observations of Psyche, which found evidence of huge depressions and impact craters across the asteroid.

“With this analysis and the previous studies of Psyche, we have reached the limit of what astronomical observations can teach us about this fascinating asteroid,” said McAdam. “Now we need to physically visit Psyche to study it up close and learn more about what appears to be a very unique planetary body.” NASA’s mission to Psyche will provide that opportunity. The spacecraft is set to launch on Oct. 12, 2023. It will arrive at the asteroid in 2029 and orbit it for at least 26 months.

Psyche’s potential to answer many questions about planet formation is a key reason why it was selected for close observation by a spacecraft. Scientists believe that planets like Earth, Mars, and Mercury have metallic cores, but they are buried too far below the planets’ mantles and crusts to see or measure directly. If Psyche is confirmed to be a planetary core, it can help scientists understand what is inside the Earth and other large planetary bodies.

Psyche’s size is also important for advancing scientific understanding of Earth-like planets. It is the largest M-type (metallic) asteroid in our solar system and is long enough to cover the distance from New York City to Baltimore, Maryland. This means Psyche is more likely to show differentiation, which is when the materials inside a planet separate from one another, with the heaviest materials sinking to the middle and forming cores.

“Every time a new study of Psyche is published, it raises more questions,” said Arredondo, who was a postdoctoral researcher at Ames on the SOFIA mission when the Psyche observations were collected. “Our findings suggest the asteroid is very complex and likely holds many other surprises. The possibility of the unexpected is one of the most exciting parts of a mission to study an unexplored body, and we look forward to gaining a more detailed understanding of Psyche’s origins.”

More about the Psyche and SOFIA missions:

Arizona State University leads the Psyche mission. A division of Caltech in Pasadena, JPL is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies in Palo Alto, California, provided the high-power solar electric propulsion spacecraft chassis.

Psyche is the 14th mission selected as part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama. NASA’s Launch Services Program, based at Kennedy, is managing the launch service.

SOFIA was a joint project of NASA and the German Space Agency at DLR. DLR provided the telescope, scheduled aircraft maintenance, and other support for the mission. NASA’s Ames Research Center in California’s Silicon Valley managed the SOFIA program, science, and mission operations in cooperation with the Universities Space Research Association, headquartered in Columbia, Maryland, and the German SOFIA Institute at the University of Stuttgart. The aircraft was maintained and operated by NASA’s Armstrong Flight Research Center Building 703, in Palmdale, California. SOFIA achieved full operational capability in 2014 and concluded its final science flight on Sept. 29, 2022.

New Simulations Shed Light on Origins of Saturn’s Rings and Icy Moons

by Frank Tavares

On a clear night, with a decent amateur telescope, Saturn and its series of remarkable rings can be seen from Earth’s surface. But how did those rings come to be? And what can they tell us about Saturn and its moons, one of the potential locations NASA hopes to search for life? A new series of supercomputer simulations has offered an answer to the mystery of the rings’ origins – one that involves a massive collision, back when dinosaurs still roamed the Earth.

According to new research by NASA and its partners, Saturn’s rings could have evolved from the debris of two icy moons that collided and shattered a few hundred million years ago. Debris that didn’t end up in the rings could also have contributed to the formation of some of Saturn’s present-day moons.

“There’s so much we still don’t know about the Saturn system, including its moons that host environments that might be suitable for life,” said Jacob Kegerreis, a research scientist at NASA’s Ames Research Center in California’s Silicon Valley. “So, it’s exciting to use big simulations like these to explore in detail how they could have evolved.”

NASA’s Cassini mission helped scientists understand just how young – astronomically speaking – Saturn’s rings and probably some of its moons are. And that knowledge opened up new questions about how they formed.

To learn more, the research team turned to the Durham University location of the Distributed Research using Advanced Computing (DiRAC) supercomputing facility in the United Kingdom. They modeled what different collisions between precursor moons might have looked like. These simulations were conducted at a resolution more than 100 times higher than previous such studies, using the open-source simulation code, SWIFT, and giving scientists their best insights into the Saturn system’s history.

Saturn’s rings today live close to the planet, within what’s known as the Roche limit – the farthest orbit where a planet’s gravitational force is powerful enough to disintegrate larger bodies of rock or ice that get any closer. Material orbiting farther out could clump together to form moons.

By simulating almost 200 different versions of the impact, the team discovered that a wide range of collision scenarios could scatter the right amount of ice into Saturn’s Roche limit, where it could settle into rings.

And, while alternative explanations haven’t been able to show why there would be almost no rock in Saturn’s rings – they are made almost entirely of chunks of ice – this type of collision could explain that.

“This scenario naturally leads to ice-rich rings,” said Vincent Eke, Associate Professor in the Department of Physics/Institute for Computational Cosmology, at Durham University and a co-author on the paper. “When the icy progenitor moons smash into one another, the rock in the cores of the colliding bodies is dispersed less widely than the overlying ice.” 

Ice and rocky debris would also have hit other moons in the system, potentially causing a cascade of collisions. Such a multiplying effect could have disrupted any other precursor moons outside the rings, out of which today’s moons could have formed.

But what could have set these events in motion, in the first place? Two of Saturn’s former moons could have been pushed into a collision by the usually small effects of the Sun’s gravity “adding up” to destabilize their orbits around the planet. In the right configuration of orbits, the extra pull from the Sun can have a snowballing effect – a “resonance” – that elongates and tilts the moons’ usually circular and flat orbits until their paths cross, resulting in a high-speed impact.

Saturn’s moon Rhea today orbits just beyond where a moon would encounter this resonance. Like the Earth’s Moon, Saturn’s satellites migrate outward from the planet over time. So, if Rhea were ancient, it would have crossed the resonance in the recent past. However, Rhea’s orbit is very circular and flat. This suggests that it did not experience the destabilizing effects of the resonance and, instead, formed more recently.

The new research aligns with evidence that Saturn’s rings formed recently, but there are still big open questions. If at least some of the icy moons of Saturn are also young, then what could that mean for the potential for life in the oceans under the surface of worlds like Enceladus? Can we unravel the full story from the planet’s original system, before the impact, through to the present day? Future research building on this work will help us learn more about this fascinating planet and the icy worlds that orbit it.

      The NESC Mechanical Systems TDT provides broad support across NASA’s mission directorates. We are a diverse group representing a variety of sub-disciplines including bearings, gears, metrology, lubrication and tribology, mechanism design, analysis and testing, fastening systems, valve engineering, actuator engineering, pyrotechnics, mechatronics, and motor controls. In addition to providing technical support, the
      TDT owns and maintains NASA-STD-5017, “Design and Development Requirements for Space Mechanisms.”

      Mentoring the Next Generation
      The NESC Mechanical Systems TDT actively participates in the Structures, Loads & Dynamics, Materials, and Mechanical Systems (SLAMS) Early Career Forum that mentors early-career engineers. The TDT sent three members to this year’s forum at WSTF, where early-career engineers networked with peers and NESC mentors, gave presentations on tasks they worked on at their home centers, and attended splinter sessions where they collaborated with mentors.

      New NASA Valve Standard to Reduce Risk and Improve Design and Reliability
      Valve issues have been encountered across NASA’s programs and continue to compromise mission performance and increase risk, in many cases because the valve hardware was not qualified in the environment as specified in NASA-STD-5017. To help address these issues, the Mechanical Systems TDT is developing a NASA standard for valves. The TDT assembled a team of subject matter experts from across the Agency representing several disciplines including mechanisms, propulsion, environmental control and life support systems, spacesuits, active thermal control systems, and materials and processes. The team has started their effort by reviewing lessons learned and best practices for valve design and hope to have a draft standard ready by the end of 2025.

      Bearing Life Testing for Reaction Wheel Assemblies
      The Mechanical Systems TDT just concluded a multiyear bearing life test on 40 motors, each containing a pair of all steel bearings of two different conformities or a pair of hybrid bearings containing silicon nitride balls. The testing confirmed that hybrid bearings outperformed their steel counterparts, and bearings with higher conformity (54%) outperformed bearings with lower conformity (52%). The team is disassembling and inspecting the bearings, and initial results have been surprising. The TDT was able to “recover” some of the bearings that failed during the life test and get them running as well as they did when testing began. Some bearings survived over five billion revolutions and appeared like new when they were disassembled and inspected. These results will be published once analysis is complete.
       
      X-57 Design Assessment
       The Mechanical Systems TDT was asked by the Aeronautics Mission Directorate to assess the design of the electric cruise motors installed on X-57. The team responded quickly to meet the Project’s schedule, making an onsite visit and attending numerous technical interchange meetings. After careful review of the design, the TDT identified areas for higher-level consideration and risk assessment and attended follow-on reviews to provide additional comments and advice.
      CLARREO Pathfinder Inner Radial Bearing Anomaly
      The Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder was designed to take highly accurate measurements of reflected solar radiation to better-understand Earth’s climate. During payload functional testing, engineers detected a noise as the HySICS pointing system was rotated from its normal storage orientation. Mechanical Systems TDT members reviewed the design and inspection reports after disassembly of the inner bearing unit, noticing contact marks on the bore of the inner ring and the shaft that confirmed that the inner ring of the bearing was moving on the shaft with respect to the outer ring. Lubricant applied to this interface resolved the noise problem and allowed the project to maintain schedule without any additional costs.
      JPL Wheel Drive Actuator Extended Life Test Independent Review Team
      A consequence of changes to its mission on Mars will require the Perseverance Rover to travel farther than originally planned. Designed to drive 20 km, the rover will now need to drive ~91 km to rendezvous and support Mars sample tube transfer to the Sample Retrieval Lander. The wheel drive actuators with integral brakes had only been life tested to 40 km, so a review was scheduled to discuss an extended life test. The OCE Science Mission Directorate Chief Engineer assembled an independent review team (IRT) that included NESC Mechanical Systems TDT members. This IRT issued findings and guidance that questioned details of the JPL assumptions and plan. Several important recommendations were made that improved the life test plan and led to the identification of brake software issues that were reducing brake life. The life test has achieved 40 km of its 137 km goal and is ongoing. In addition, software updates were sent to the rover to improve brake life.

      Orion Crew Module Hydrazine Valve
      When an Orion crew module hydrazine valve failed to close, the production team asked the Mechanical Systems TDT for help. A TDT member attended two meetings and then visited the valve manufacturer, where it was determined this valve was a scaled-down version of the 12-inch SLS prevalve that was the subject of a previous NESC assessment and shared similar issues. The Orion Program requested NESC materials and mechanical systems support. The Mechanical Systems TDT member then worked closely with a Lockheed Martin (LM) Fellow for Mechanisms to review all the valve vendor’s detailed drawings and assembly procedures and document any issues. A follow-on meeting was held to brief both the LM and NASA Technical Fellows for Propulsion that a redesign and requalification was recommended. These recommendations have now been elevated to the LM Vice President for Mission Success and the LM Chief Engineer for Orion.

      Latha Balijepalle, a senior database administrator at NASA Ames, encourages others to take a risk and pursue challenges in their work, like trying something new that might open doors to a new opportunity.NASA/Brandon Torres Navarrete When Madhavi Latha Balijepalle noticed that her morning commute took her past NASA Ames Research Center in California’s Silicon Valley, she set a new career goal for herself: working for NASA. 
      “I started manifesting it, thinking about it every day as I drove by. When I started looking for a new job, I saw an opening and decided to apply,” said Balijepalle, a senior database administrator working at the Airspace Operations Laboratory (AOL) at NASA Ames.  
      Eight and a half years later, she supports the researchers and developers who research next-generation solutions to advance aircraft technology and air traffic management. 
      A journey into the unknown 
      Balijepalle’s journey to NASA started thousands of miles away. She grew up in a small town in southern India, studying electrical engineering in college and establishing a career in information technology, working in C++ and Python. 
      When her husband found a job opportunity in the United States, Balijepalle’s life took an unexpected turn. 
      “I never planned to move to America,” said Balijepalle. “It was not easy to come here, even though my husband had a job. I stayed in India for almost nine months, before he found a different job that would help us with my visa and documentation.” 
      After settling into her new country, growing her family, and developing in her new career, Balijepalle began to ponder her dream job at NASA. She and her younger daughter, a fellow space fan, enjoyed talking about the agency’s work in space, and when a Linux administrator position opened up, she jumped at the chance. 
      A dream job becomes reality 
      At the lab, Balijepalle was initially responsible for managing the lab’s Linux servers and applications. Today, she also supports researchers and developers with development, automation, and deployment of their work. 
      “Latha is the lifeblood of the lab,” said Jeff Homola, co-leader of the Airborne Operations Laboratory at NASA Ames. “Without her unwavering dedication to making sure our systems are safe, secure, up to date, and running smoothly, we would not be able to do what we do in the lab.” 
      One of Balijepalle’s proudest achievements during her NASA career is her language skills. Growing up, she spoke Telugu and Hindi, and learned English, but communication was still a challenge when she arrived at NASA. 
      “I spoke English when I came to America, but not as well, and not using the technical language we use at NASA,” said Balijepalle. “I’m proud that I’ve improved my communications skills.” 
      “Step outside your comfort zone” 
      Looking back on the commute that changed her life, Balijepalle says she owes it all to being up to the challenge. 
      “I wasn’t a risk taker, I didn’t think about stepping outside my comfort zone, but as I drove by NASA Ames each day, I started to think about astronauts. They step outside their comfort zone and leave the planet, so maybe I could take a risk, too.” 
      For those who also dream of working at NASA one day, Balijepalle has some advice: try doing it her way. 
      “Start thinking about it and manifesting your dream. Maybe it will come true, and maybe it won’t, but you might as well try.”

Working with multiple partners, our scientists and engineers helped inform ecosystem management by joining satellite measurements of Earth with animal tracking data. In collaboration with the U.S. Geological Survey, a NASA team continued testing a specialized instrument package to stay in-the-know about changes in river flow rates. 

      Revealing the Mysteries of Asteroids in Our Solar System

      NASA’s Ames Research Center Celebrates 85 Years of Innovation
      by Rachel Hoover
      Ames Research Center in California’s Silicon Valley pre-dates a lot of things. The center existed before NASA – the very space and aeronautics agency it’s a critical part of today. And of all the marvelous advancements in science and technology that have fundamentally changed our lives over the last 85 years since its founding, one aspect has remained steadfast; an enduring commitment to what’s known by some on-center simply as, “an atmosphere of freedom.” 
      The NACA Ames laboratory in 1944.Image credit: NASA Years before breaking ground at the site that would one day become home to the world’s preeminent wind tunnels, supercomputers, simulators, and brightest minds solving some of the world’s toughest challenges, Joseph Sweetman Ames, the center’s namesake, described a sentiment that would guide decades of innovation and research: 
      “My hope is that you have learned or are learning a love of freedom of thought and are convinced that life is worthwhile only in such an atmosphere,” he said in an address to the graduates of Johns Hopkins University in June 1935.
      That spirit and the people it attracted and retained are a crucial part of how Ames, along with other N.A.C.A. research centers, ultimately made technological breakthroughs that enabled humanity’s first steps on the Moon, the safe return of spacecraft through Earth’s atmosphere, and many other discoveries that benefit our day-to-day lives.
      Russell Robinson momentarily looks to the camera while supervising the first excavation at what would become Ames Research Center.Image credit: NACA “In the context of my work, an atmosphere of freedom means the freedom to pursue high-risk, high-reward, innovative ideas that may take time to fully develop and — most importantly — the opportunity to put them into practice for the benefit of all,” said Edward Balaban, a researcher at Ames specializing in artificial intelligence, robotics, and advanced mission concepts.
      Balaban’s career at Ames has involved a variety of projects at different stages of development – from early concept to flight-ready – including experimenting with different ways to create super-sized space telescopes in space and using artificial intelligence to help guide the path a rover might take to maximize off-world science results. Like many Ames researchers over the years, Balaban shared that his experience has involved deep collaborations across science and engineering disciplines with colleagues all over the center, as well as commercial and academic partners in Silicon Valley where Ames is nestled and beyond. This is a tradition that runs deep at Ames and has helped lead to entirely new fields of study and seeded many companies and spinoffs.
      Before NASA, Before Silicon Valley: The 1939 Founding of Ames Aeronautical Laboratory “In the fields of aeronautics and space exploration the cost of entry can be quite high. For commercial enterprises and universities pursuing longer term ideas and putting them into practice often means partnering up with an organization such as NASA that has the scale and multi-disciplinary expertise to mature these ideas for real-world applications,” added Balaban.
      “Certainly, the topics of inquiry, the academic freedom, and the benefit to the public good are what has kept me at Ames,” reflected Ross Beyer, a planetary scientist with the SETI Institute at Ames. “There’s not a lot of commercial incentive to study other planets, for example, but maybe there will be soon. In the meantime, only with government funding and agencies like NASA can we develop missions to explore the unknown in order to make important fundamental science discoveries and broadly share them.”
      For Beyer, his boundary-breaking moment came when he searched – and found – software engineers at Ames capable and passionate about open-source software to generate accurate, high-resolution, texture-mapped, 3D terrain models from stereo image pairs. He and other teams of NASA scientists have since applied that software to study and better understand everything from changes in snow and ice characteristics on Earth, as well as features like craters, mountains, and caves on Mars or the Moon. This capability is part of the Artemis campaign, through which NASA will establish a long-term presence at the Moon for scientific exploration with commercial and international partners. The mission is to learn how to live and work away from home, promote the peaceful use of space, and prepare for future human exploration of Mars. 
      “As NASA and private companies send missions to the Moon, they need to plan landing sites and understand the local environment, and our software is freely available for anyone to use,” Beyer said. “Years ago, our management could easily have said ‘No, let’s keep this software to ourselves; it gives us a competitive advantage.’ They didn’t, and I believe that NASA writ large allows you to work on things and share those things and not hold them back.” 
      When looking forward to what the next 85 years might bring, researchers shared a belief that advancements in technology and opportunities to innovate are as expansive as space itself, but like all living things, they need a healthy atmosphere to thrive. Balaban offered, “This freedom to innovate is precious and cannot be taken for granted. It can easily fall victim if left unprotected. It is absolutely critical to retain it going forward, to ensure our nation’s continuing vitality and the strength of the other freedoms we enjoy.”

      Ames Aeronautical Laboratory.Image credit: NACA Today Marks the Retirement of the Astrogram Newsletter
      by Astrid Albaugh
      For 66 years, the Astrogram has told the story of NASA’s Ames Research Center. Over those six-plus decades, the newsletter has documented hundreds of missions led by Ames, the progression of Hangar One’s reclamation, space shuttle launches with Ames’ payloads aboard them, countless VIP visits, and everything in between.
      Ames published the first edition of the Astrogram in October 1958, coinciding with the transition of the center from its original incarnation as the National Advisory Committee for Aeronautics Ames Aeronautical Laboratory to a National Aeronautics and Space Administration (NASA) research center.
      The newsletter has evolved over time, alongside the center. From October 1958 through January 2016, the Astrogram was published in print, before a digital edition was developed. In January 2016, the Astrogram transitioned to a digital-only format. Below are examples of some of the Astrogram issues from over the years. More are forthcoming from 1998 and prior once they are retrieved from the archives.
      October 2014 Astrogram September 2010 Astrogram I have served as the editor of the Astrogram since February 1998. Over the past quarter century, it has been an interesting, and sometimes quite challenging, task for me to capture the breadth and depth of Ames’s story and ensure that we always published the newsletter on time. I still remember trekking over to the center’s imaging office to review the physical negatives and images that the Ames photographers had taken of events onsite and select the most compelling photos. I used a very early version of visual design software to craft the layout. When the paper was completed, I’d file it onto a CD and then hand it to the courier who would drive from the San Francisco printshop to pick it up from me. Once and awhile, someone would request to have an additional feature added, requiring multiple trips up the 101 and back. Sometimes I’d come in on the weekends to work on the paper, due to late submissions, much to the chagrin of my kids.
      July 2007 Astrogram It has been a pleasure serving as the editor over the past quarter century, almost as many years as my kids are old. A person once asked me if I had changed my name to Astrid since it’s so like the word Astrogram. Any relationship between the newsletter and my name is simply serendipity. I have enjoyed being behind the scenes, mostly working diligently at my computer. Many at Ames know my name because of the newsletter but may have never met me in person. It’s been amusing sometimes when I encounter someone who can’t put a finger as to why they knew my name but didn’t recognize me standing in front of them. Their usual response when they realized why they know me was, “Ah, Astrid of the Astrogram.”
      March 20, 1998 Astrogram Just as NASA innovates, the content of the Astrogram has to innovate as well. Many of the stories that you used to read in the Astrogram, you can now find on our NASA Ames web page here. If you would like to access past, archived issues of the Astrogram, going back to 1958, please consult the Ames Research Center Archives. I will continue to help tell Ames’s story, just using new platforms.
      Whether this is your first issue or you have been an Astrogram supporter for decades, thank you for reading!
