It was processed using a color-enhancing Gaussian stretch algorithm. NASA/JPL-Caltech/LANL/CNES/IRAP. I have always loved the mountains. Growing up on the flat plains of Midwestern USA, every summer I looked forward to spending a few days on alpine trails while on vacation. Climbing upward from the trailhead, the views changed constantly. After climbing a short distance, the best views were often had by looking back down on where we had started. As we climbed higher, views of the valleys below eventually became shrouded in haze. Near the top we got our last views of the region behind us; then it disappeared from view as we hiked over the pass and started down the other side. Approaching the summit held a special reward, as the regions beyond the pass slowly revealed themselves. Frequent stops to catch our breath during our ascent were used to check the map to identify the new peaks and other features that came into view. Sometimes the pass was an exciting gateway to a whole new area to explore. This ever-changing landscape has been our constant companion over the last five months as Perseverance first climbed out of Neretva Vallis, then past “Dox Castle,” and “Pico Turquino.” We stopped at “Faraway Rock” on Sol 1282 to get a panorama of the crater floor. More recently, we could see many more peaks of the crater rim. As Perseverance crested the summit of “Lookout Hill,” half a mile (800 meters) above the traverse’s lowest point, we got our first views beyond the crater rim, out into the great unknown expanse of Mars’ Nili Planum, including the upper reaches of Neretva Vallis and the locations of two other candidate landing sites that were once considered for Perseverance. As the rover crested the summit, Mastcam-Z took a large panoramic mosaic, and team members are excitedly poring over the images, looking at all the new features. With Perseverance’s powerful cameras we can analyze small geological features such as boulders, fluvial bars, and dunes more than 5 miles (8 kilometers) distant, and major features like mountains up to 35 miles (60 kilometers) away. One of our team members excitedly exclaimed, “This is an epic moment in Mars exploration!” While Curiosity has been climbing “Mount Sharp” for 10 years, and Spirit and Opportunity explored several smaller craters, no extraterrestrial rover has driven out of such a huge crater as Jezero to see a whole new “continent” ahead. We are particularly excited because it is potentially some of the most ancient surface on the Red Planet. Let’s go explore it! Perseverance is now in Gros Morne quad, named for a beautiful Canadian national park in Newfoundland, and we will be naming our targets using locations and features in the national park. For the drive ahead, described in a video in a recent press release, our next destination is on the lower western edge of the Jezero crater rim at a region named “Witch Hazel Hill.” Perseverance made more than 250 meters of progress over the weekend (about 820 feet) and is already at the upper part of Witch Hazel Hill, a location called “South Arm.” Much of the climb up the crater rim was on sandy material without many rocks to analyze. Witch Hazel Hill appears to have much more exposed rock, and the science team is excited about the opportunity for better views and analyses of the geology directly beneath our wheels.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The SpaceX Dragon Freedom spacecraft carrying NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov approaches the International Space Station as it orbited 261 miles above Ontario, Canada, near James Bay. NASA published a new report Thursday highlighting 17 agency mechanisms that have directly and indirectly supported the development and growth of the U.S. commercial space sector for the benefit of humanity. The report, titled Enabling America on the Space Frontier: The Evolution of NASA’s Commercial Space Development Toolkit, is available on the agency’s website. “This is the most extensive and comprehensive historical analysis produced by NASA on how it has contributed to commercial space development over the decades,” said Alex MacDonald, NASA chief economist. “These efforts have given NASA regular access to space with companies, such as SpaceX and Rocket Lab, modernizing our communications infrastructure, and even led to the first private lunar lander thanks to Intuitive Machines. With commercial space growth accelerating, this report can help agency leaders and stakeholders assess the numerous mechanisms that the agency uses to support this growth, both now and in the future.” Throughout its history, NASA has supported the development of the commercial space sector, not only leading the way in areas such as satellite communications, launch, and remote sensing, but also developing new contract and operational models to encourage commercial participation and growth. In the last three decades, NASA has seen the results of these efforts with commercial partners able to contribute more to missions across NASA domains, and increasingly innovative agency-led efforts to engage, nurture, and integrate these capabilities. These capabilities support the agency’s mission needs, and have seen a dramatic rise in importance, according to the report. NASA has nurtured technology, companies, people, and ideas in the commercial space sector, contributing to the U.S. and global economies, across four distinct periods in the agency’s history: 1915–1960: NASA’s predecessor, the National Advisory Committee on Aeronautics (NACA), and NASA’s pre-Apollo years. 1961–1980: Apollo era. 1981–2010: Space shuttle era. 2011–present: Post-shuttle commercial era. Each of these time periods are defined by dominant technologies, programs, or economic trends further detailed in the report. Though some of these mechanisms are relatively recent, others have been used throughout the history of NASA and NACA, leading to some overlap. The 17 mechanisms are as follows: Contracts and Partnership Agreements Research and Technology Development (R&TD) Dissemination of Research and Scientific Data Education and Workforce Development Workforce External Engagement and Mobility Technology Transfer Technical Support Enabling Infrastructure Launch Direct In-Space Support Standards and Regulatory Framework Support Public Engagement Industry Engagement Venture Capital Engagement Market Stimulation Funding Economic Analysis and Due Diligence Capabilities Narrative Encouragement NASA supports commercial space development in everything from spaceflight to supply chains. Small satellite capabilities have inspired a new generation of space start-ups, while new, smaller rockets, as well as new programs are just starting. Examples include CLPS (Commercial Lunar Payload Services), commercial low Earth orbit destinations, human landing systems, commercial development of NASA spacesuits, and lunar terrain vehicles. The report also details many indirect ways the agency has contributed to the vibrance of commercial space, from economic analyses to student engagement. The agency’s use of commercial capabilities has progressed from being the exception to the default method for many of its missions. The current post-shuttle era of NASA-supported commercial space development has seen a level of technical development comparable to the Apollo era’s Space Race. Deploying the 17 commercial space development mechanisms in the future are part of NASA’s mission to continue encouraging commercial space activities.

NASA has taken a big step forward in how engineers will assemble and stack future SLS (Space Launch System) rockets for Artemis Moon missions inside the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. The VAB’s High Bay 2 has been outfitted with new tooling to facilitate the vertical integration of the SLS core stage. That progress was on full display in mid-December when teams suspended the fully assembled core stage 225 feet in the air inside the high bay to complete vertical work before it is stacked on mobile launcher 1, allowing teams to continue solid rocket booster stacking simultaneously inside High Bay 3 for Artemis II. The fully assembled SLS (Space Launch System) core stage for the Artemis II test flight is suspended 225 feet in the air inside the newly renovated High Bay 2 at Kennedy’s Vehicle Assembly Building. The core stage was lifted to enable engineers to complete work before it is stacked on mobile launcher 1 with other rocket elements. With the move to High Bay 2, technicians now have 360-degree tip to tail access to the core stage, both internally and externally.NASA With the move to High Bay 2, technicians with NASA and Boeing now have 360-degree tip to tail access to the core stage, both internally and externally. Michigan-based supplier Futuramic Tool and Engineering led the design and build of the Core Stage Vertical Integration Center tool that will hold the core stage in a vertical position. “High Bay 2 tooling was originally scheduled to be complete for Artemis III. We had an opportunity to get it done earlier and that will put us in a good posture to complete work earlier than planned prior to moving the core stage for Artemis II into the full integrated stack over into in High Bay 3,” said Chad Bryant, deputy manager of the NASA SLS Stages Office. “This gives us an opportunity to go in and learn how to rotate, lift, and move the core stage into the high bay.” This move also doubles the footprint of useable space within the VAB, giving engineers access to both High Bay 2 and High Bay 3 simultaneously, while also freeing up space at NASA’s Michoud Assembly Facility in New Orleans to continue work on the individual elements for future SLS core stages. High Bay 2 has a long history of supporting NASA exploration programs: during Apollo, High Bay 2, one of four high bays inside the VAB, was used to stack the Saturn V rocket. During the Space Shuttle Program, the high bay was used for external tank checkout and storage and as an extra storage area for the shuttle. Under the new assembly model beginning with Artemis III, all the major structures for the SLS core stage will continue to be fully produced and manufactured at NASA Michoud. Upon completion of manufacturing and thermal protection system application, the engine section will be shipped to Kennedy for final outfitting. The 212-foot-tall SLS (Space Launch System) core stage for NASA Artemis II is seen being moved from a horizontal position to a vertical position in High Bay 2 at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. With the move to High Bay 2, NASA and Boeing technicians now have 360-degree access to the core stage both internally and externally. (NASA) “Core stage 3 marks a significant change in the way we build core stages,” said Steve Wofford, manager of the SLS Stages Office. “The vertical capability in High Bay 2 allows us to perform parallel processing from the top to bottom of the stage. It’s a much more efficient way to build core stages. This new capability will streamline final production efforts, allowing our team to have 360-degree access to the stage, both internally and externally.” The fully assembled core stage for Artemis II arrived July 23, 2024, at Kennedy, where it remained horizontal inside the VAB transfer aisle until its recent lift into the newly outfitted high bay. Teams at NASA Michoud are outfitting the remaining core stage elements for Artemis III and preparing to horizontally join them. The four RS-25 engines for the Artemis III mission are complete at NASA’s Stennis Space Center in Bay St. Louis, Mississippi, and will be transported to NASA Kennedy in 2025. Major core stage and exploration upper stage structures are in work at NASA Michoud for Artemis IV and beyond. NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) When it comes to building spaceflight missions, the software is at least as important as the hardware. For computer engineer Nargess Memarsadeghi, having a hand in the programming is like getting to go along for the ride. Name: Nargess Memarsadeghi Title: Associate Branch Head, Software Systems Engineering Branch Formal Job Classification: Supervisory Computer Engineer Organization: Software Systems Engineering Branch, Software Engineering Division, Engineering Directorate (Code 581) Nargess Memarsadeghi is the associate branch head of the Software Systems Engineering branch at NASA’s Goddard Space Flight Center in Greenbelt, Md.Courtesy of Nargess Memarsadeghi What do you do and what is most interesting about your role here at Goddard? As associate branch head for the Software Systems Engineering Branch, I spend half of my time supporting the branch head on internal functions, different planning activities, and supervising our employees who are senior software systems engineers and often team leads themselves. For the other half of my time, I work on a technical project. Currently, I am supporting the Human Landing Systems (HLS) project. I am a member of NASA HLS Software Insight Team working with NASA’s Marshall Space Flight Center in Huntsville, Alabama, and Johnson Space Center in Houston, and industry partners SpaceX and Blue Origin to meet software requirements and milestones, and to ensure the Artemis campaign succeeds in taking astronauts to the Moon. I enjoy learning about various NASA missions and being part of them either by supporting our branch employees who work on these missions or by being a project team member and making technical contributions directly. Why did you become a software engineer? I always loved math and sciences. Software engineering seemed like a good and practical way to apply math to different scientific and engineering applications. What is your educational background? I got my bachelor’s (2001), master’s (2004), and doctorate (2007) degrees in computer science from the University of Maryland at College Park. How did you come to Goddard? I joined Goddard in 2001 right after college. The university had a recruitment event at its career center. I signed up for an interview with NASA, which went well. I then got an invitation for an onsite interview, and then an offer to join Goddard as a computer engineer. What is your supervisory style? I have been supervising on average 10 employees. We have tag-ups every two weeks to learn about their work and see if they have any issues or need anything from management. We keep in constant communication which goes both ways. I have an open-door policy. I try to match an employee’s interests and expertise to their work. I am willing to hear their concerns and address them to the best of my ability or putting them in contact with those who can. I enjoy learning about their work and celebrating the achievements. What are some of the most exciting projects and missions that the Software Systems Engineering Branch is involved with? We provide end-to-end software systems engineering support to many high-impact missions, like the upcoming flagship astrophysics Roman Space Telescope mission. We support Roman’s software systems, as well as its testing and assembly with one of our software products, the Goddard Dynamic Simulator. Our team also supports a variety of Earth science missions, such as the Joint Polar Satellite Systems (JPSS), GOES-R, and GOES-U, all of which NASA supports on behalf of the National Oceanic and Atmospheric Administration (NOAA). We also develop and manage different ground segment software systems for different missions including PACE, TSIS-II, and others. What are some of your career highlights so far? One was being part of the James Webb Space Telescope team and working on stability testing of microshutters. Webb is a huge, multinational observatory making many scientific discoveries. Another is being part of the Dawn mission’s satellite working group searching for moons of the asteroid Vesta and dwarf planet Ceres. I worked on this from prelaunch through launch and operations. We were some of the first to see the scientific images soon after being downlinked. It felt like going on a ride with the spacecraft itself. I would add my more recent work on the Roman Space Telescope. In general, I really enjoyed working on various missions during their different stages of their life cycle. I got to see the whole picture of how software is used for missions, from technology development to post-launch. What advice do you give your graduate students and interns as a mentor? I emphasize that they also need to work on their communication skills, leadership skills, and team building. I tell them to focus not just on their technical skills but also on their interpersonal skills both written and oral. NASA has a lot of collaborative projects and being able to effectively communicate across different levels is crucial for mission success. Whom do you wish to thank? I would like to thank my family for their support. I would also like to thank my past teachers and mentors who made a big difference in me and positively impacted my life. What do you do to relax? I like going for long walks, spending time with family and friends, and doing activities with my son including attending his piano recitals. Who is your favorite author? As a young reader, I enjoyed reading Jules Verne. I also enjoy reading poetry. My favorites are Robert Frost, Emily Dickinson, and Persian poets Sohrab Sepehri and Saadi Shirazi. What motto do you live by? Be the change you want to see in the world. By Elizabeth M. Jarrell NASA’s Goddard Space Flight Center, Greenbelt, Md.

Download PDF: Statistical Analysis Using Random Forest Algorithm Provides Key Insights into Parachute Energy Modulator System Energy modulators (EM), also known as energy absorbers, are safety-critical components that are used to control shocks and impulses in a load path. EMs are textile devices typically manufactured out of nylon, Kevlar® and other materials, and control loads by breaking rows of stitches that bind a strong base webbing together as shown in Figure 1. A familiar EM application is a fall-protection harness used by workers to prevent injury from shock loads when the harness arrests a fall. EMs are also widely used in parachute systems to control shock loads experienced during the various stages of parachute system deployment. Random forest is an innovative algorithm for data classification used in statistics and machine learning. It is an easy to use and highly flexible ensemble learning method. The random forest algorithm is capable of modeling both categorical and continuous data and can handle large datasets, making it applicable in many situations. It also makes it easy to evaluate the relative importance of variables and maintains accuracy even when a dataset has missing values. Random forests model the relationship between a response variable and a set of predictor or independent variables by creating a collection of decision trees. Each decision tree is built from a random sample of the data. The individual trees are then combined through methods such as averaging or voting to determine the final prediction (Figure 2). A decision tree is a non-parametric supervised learning algorithm that partitions the data using a series of branching binary decisions. Decision trees inherently identify key features of the data and provide a ranking of the contribution of each feature based on when it becomes relevant. This capability can be used to determine the relative importance of the input variables (Figure 3). Decision trees are useful for exploring relationships but can have poor accuracy unless they are combined into random forests or other tree-based models. The performance of a random forest can be evaluated using out-of-bag error and cross-validation techniques. Random forests often use random sampling with replacement from the original dataset to create each decision tree. This is also known as bootstrap sampling and forms a bootstrap forest. The data included in the bootstrap sample are referred to as in-the-bag, while the data not selected are out-of-bag. Since the out-of-bag data were not used to generate the decision tree, they can be used as an internal measure of the accuracy of the model. Cross-validation can be used to assess how well the results of a random forest model will generalize to an independent dataset. In this approach, the data are split into a training dataset used to generate the decision trees and build the model and a validation dataset used to evaluate the model’s performance. Evaluating the model on the independent validation dataset provides an estimate of how accurately the model will perform in practice and helps avoid problems such as overfitting or sampling bias. A good model performs well on both the training data and the validation data. The complex nature of the EM system made it difficult for the team to identify how various parameters influenced EM behavior. A bootstrap forest analysis was applied to the test dataset and was able to identify five key variables associated with higher probability of damage and/or anomalous behavior. The identified key variables provided a basis for further testing and redesign of the EM system. These results also provided essential insight to the investigation and aided in development of flight rationale for future use cases. For information, contact Dr. Sara R.

Download PDF: Contact Dynamics Predictions Utilizing theNESC Parameterless Contact Model Modeling the capture of the Mars Sample Return (MSR) Orbiting Sample (OS) involves understanding complex dynamic behavior, which includes the OS making contact against the interior of the capture enclosure. The MSR Program required numerical verification of the contact dynamics’ predictions produced using their commercial software tools. This commercial software used “free” parameters to set up the contact modeling. Free parameters (also known as free variables) are not based on contact physics. The commercial contact model used by MSR required seven free parameters including a Hertzian contact stiffness, surface penetration, stiffening exponent, penetration velocity, contact damping, maximum penetration depth for the contact damping value, and a smoothing function. An example of a parameter that is not free is coefficient of friction, which is a physics-based parameter. Consider the free parameter, contact stiffness. Contact stiffness is already present in the finite element model’s (FEM) stiffness matrix where the bodies come into contact, and surface penetration is disallowed in a physically realizable contact model, as FEM meshes should not penetrate one another during contact (i.e., the zero-contact limit penetration constraint condition). As such, with each set of selected free parameters generating a different contact force signature, additional numerical verification is required to guide setting these parameters. Contact modeling is nonlinear. This means that the stiffness matrices of contacting bodies are continuously updated as the bodies come into contact, potentially recontact (due to vibrations), and disengage. The modal properties of contacting bodies continuously change with state transitions (e.g., stick-to-slip). Some contact models have been proposed and incorporated in commercial finite element analysis solvers, and most involve static loading. A relatively smaller number involve dynamics, which has historically proven challenging. In 2005, NASA conducted a study testing several commercial contact solvers in predicting contact forces in transient dynamic environments. This was necessitated by the Space Shuttle Program (SSP)—after the February 2003 Columbia accident— deciding to include contact dynamics in the Space Shuttle transient coupled loads analysis (CLA) to capture the impact of contact nonlinearities. This rendered the entire CLA nonlinear. The study found major difficulties executing nonlinear CLAs in commercial software. A nonlinear solver developed by the NESC and Applied Structural Dynamics (ASD) that was able to produce physically realizable results was numerically verified by NASA and later experimentally validated as well. This nonlinear solver was subsequently utilized to execute all NASA SSP CLAs (i.e., crewed space flights) from 2005 to the final flight in 2011, as well as currently supporting the SLS Program. The objective of the MSR contact verification work was to provide data that could be used by the MSR team to help define the free parameters listed above for the commercial tool contact model. The NESC/ASD solver was used to model contact between simple cantilever and free beams, deriving contact forces and relative displacements. These resulting data can be used to determine parameter values for more complex structures. Two of the modeled configurations, one for axial contact (Figure 1) and the other for stick/friction (Figure 2), and sample results from the NESC nonlinear dynamic analyses are presented in Figures 1 and 2.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) With a shared commitment to fostering U.S. economic growth that benefits the American public, NASA’s Space Technology Mission Directorate and the Department of Commerce’s U.S. Patent and Trademark Office (USPTO) have signed a memorandum of understanding to strengthen collaboration in transferring federally-developed technology into the private sector, known as tech transfer. “NASA has to invent new technology every day to carry out audacious missions like building an outpost on the Moon or looking for signs of life on the frozen moons of distant planets,” said Clayton Turner, associate administrator of the agency’s Space Technology Mission Directorate. “That is one of our greatest strengths. And with the help of the U.S. Patent and Trademark Office, we’re streamlining the process of getting those inventions into the hands of the public, boosting the economy, and benefiting everyone on Earth along the way.” The agency’s Space Technology Mission Directorate and USPTO have been working together to share information and cooperate in mutual areas of interest, find ways to advance both agencies’ technology transfer missions, identify barriers to technology transfer, and coordinate initiatives to overcome those barriers. By combining expertise, both agencies are driving inclusive innovation and adoption of best practices, which will advance commercialization of the space agency’s most cutting-edge technology. As part of the new agreement, NASA and USPTO are conducting an extensive study of technology transfer best practices across university and federal labs. The effort will increase opportunities for learning and growth in the technology transfer community. “NASA’s Technology Transfer program and the U.S. Patent and Trademark Office had candid conversations with dozens of tech transfer experts about what we could do better,” said Dan Lockney, executive for NASA’s Technology Transfer program. “I can’t wait to share what we’ve learned with the entire tech transfer community nationwide. We look forward to addressing common challenges, and this paper will offer some assurance that we are on a solid, strong path to transferring technologies effectively.” The two agencies will publish a detailed study of their findings, which will be shared at the Federal Laboratory Consortium for Technology Transfer’s national meeting in the spring. The effort will increase opportunities for learning and growth in the technology transfer community. “We are excited to join NASA’s Space Technology Mission Directorate in publishing and sharing this insight with the larger tech transfer community, so that everyone can benefit from the successes and lessons learned from our study participants,” said Parikha Solanki, senior advisor at the U.S. Patent and Trademark Office. “We hope that the impact of this study will extend well beyond the paper, such that it might be a springboard for ongoing dialogue and knowledge sharing between tech transfer practitioners across institutions, ultimately for the benefit of the public at large.” Learn more about NASA’s Technology Transfer Program: https://go.nasa.gov/3VEZcmZ Share Details Last Updated Dec 19, 2024 Related TermsTechnology TransferSpinoffsTechnologyTechnology Transfer & Spinoffs Explore More 5 min read NASA Mars Orbiter Spots Retired InSight Lander to Study Dust Movement Article 3 days ago 3 min read NASA Gives The World a Brake Article 1 week ago 3 min read An Electronic Traffic Monitor for Airports Ground traffic management program saves passengers and airlines time while cutting fuel costs Article 3 weeks ago Keep Exploring Discover Related Topics Technology Transfer & Spinoffs TechPort – Find it, Build it, Share it.

As 1969, an historic year that saw not just one but two successful human lunar landings, drew to a close, NASA continued preparations for its planned third Moon landing mission, Apollo 13, then scheduled for launch on March 12, 1970. The Apollo 13 prime crew of Commander James A. Lovell, Command Module Pilot (CMP) Thomas K. “Ken” Mattingly, and Lunar Module Pilot (LMP) Fred W. Haise, and their backups John W. Young, John L. “Jack” Swigert, and Charles M. Duke, continued intensive training for the mission. NASA announced the selection of the Fra Mauro region of the Moon as the prime landing site for Apollo 13, favored by geologists because it forms an extensive geologic unit around Mare Imbrium, the largest lava plain on the Moon. The Apollo 13 Saturn V rolled out to its launch pad. Apollo 11 The Apollo 11 astronauts meet Canadian Prime Minister Pierre Trudeau, left, on Parliament Hill in Ottawa.

Apollo 11 astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrinhad returned from their Giantstep Presidential goodwill tour on Nov. 5, 1969. Due to scheduling conflicts, a visit to Canada could not be included in the same time frame as the rest of the tour, so the astronauts made a special trip to Ottawa and Montreal on Dec. 2 and 3, meeting with local officials. Apollo 11 astronaut Neil A. Armstrong, left, and comedian Bob Hope perform for the troops in Korat, Thailand. Armstrong, in blue flight suit, shakes hands with servicemen in Long Binh, South Vietnam. Armstrong, left, and Hope entertain the crowd in Cu Chi, South Vietnam. Armstrong joined famed comedian Bob Hope’s USO Christmas tour in December 1969. He participated in several shows at venues in South Vietnam, Thailand, and Guam, kidding around with Hope and answering questions from the assembled service members. He received standing ovations and spent much time shaking hands with the troops. The USO troupe also visited the hospital ship U.S.S. Sanctuary (AH-17) stationed in the South China Sea. Apollo 12 For the first time in nearly four weeks, on Dec. 10, Apollo 12 astronauts Charles “Pete” Conrad, Richard F. Gordon, and Alan L. Bean stepped out into sunshine and breathed unfiltered air. Since their launch on Nov. 14, 1969, the trio had traveled inside their spacecraft for 10 days on their mission to the Moon and back, wore respirators during their recovery in the Pacific Ocean, stayed in the Mobile Quarantine Facility during the trip from the prime recovery ship U.S.S. Hornet back to Houston, and lived in the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Like the Apollo 11 crew before them, Conrad, Gordon, and Bean exhibited no symptoms of any infections with lunar microorganisms and managers declared them fit to be released from quarantine. MSC Director Robert L. Gilruth, other managers, and a crowd of well-wishers greeted Conrad, Gordon, and Bean.

Addressing the crowd gathered outside the LRL, Conrad commented that “the LRL was really quite pleasant,” but all three were glad to be breathing non man-made air! While the men went home to their families for a short rest, work inside the LRL continued. Scientists began examining the first of the 75 pounds of rocks returned by the astronauts as well as the camera and other hardware they removed from Surveyor 3 for effects of 31 months exposed to the harsh lunar environment. Preliminary analysis of the TV camera that failed early during their first spacewalk on the lunar surface indicated that the failure was due to partial burnout of the Videocon tube, likely caused by the crew accidentally pointing the camera toward the Sun. Other scientists busied themselves with analyzing the data returning from the Apollo Lunar Surface Experiment Package (ALSEP) instruments Conrad and Bean deployed on the lunar surface. Mission planners examining the photographs taken from lunar orbit of the Fra Mauro area were confident that the next mission, Apollo 13, would be able to make a safe landing in that geologically interesting site, the first attempt to land in the lunar highlands. After taking their first steps in the sunshine, Apollo 12 astronauts Charles “Pete” Conrad, left, Alan L. Bean, and Richard F. Gordon address a large group of well-wishers outside the Lunar Receiving Laboratory. Bean, left, Gordon, and Conrad during their postflight press conference. Two days after leaving the LRL, Conrad, Gordon, and Bean held their postflight press conference in the MSC auditorium. Addressing the assembled reporters, the astronauts first introduced their wives as their “number one support team,” then provided a film and photo summary of their mission, and answered numerous questions. Among other things, the astronauts praised the spacesuits they wore during the Moon walks, indicating they worked very well and, looking ahead, saw no impediments to longer excursions on future missions. Their only concern centered around the ever-present lunar dust that clung to their suits, raising that as a potential issue for future lunar explorers.

White House of the Apollo 12 astronauts and their wives with President Richard M. Nixon, First Lady Pat Nixon, and their daughter Tricia Nixon. Conrad, Gordon, and Bean returned to NASA’s Kennedy Space Center (KSC) in Florida on Dec. 17, where their mission began more than a month earlier and nearly ended prematurely when lightning twice struck their Saturn V rocket. KSC Director Kurt H. Debus presented each astronaut with a framed photograph of their launch in front of 8,000 workers assembled in the Vehicle Assembly Building (VAB). Of their nearly ill-fated liftoff Conrad expressed his signature confidence, “Had we to do it again, I would launch exactly under the same conditions.” Guenter Wendt and his pad closeout team had collected a piece of grounding rod from the umbilical tower, cut it into three short pieces, mounted them with the inscription “In fond memory of the electrifying launch of Apollo 12,” and presented them to the astronauts. Three days later, President Richard M. Nixon and First Lady Pat Nixon welcomed Conrad, Gordon, and Bean and their wives Jane, Barbara, and Sue, respectively, to a dinner at the White House. After dinner, they watched a film about the Apollo 12 mission as well as the recently released motion picture Marooned about three astronauts stranded in space. President Nixon requested that the astronauts pay a visit to former President Lyndon B. Johnson, who for many years championed America’s space program, and brief him on their mission, which they did in January 1970. The Alan Bean Day parade in Fort Worth.

On Dec. 22, the city of Fort Worth, Texas, honored native son Bean, with Conrad, Gordon, and their families joining him for the Alan Bean Day festivities. An estimated 150,000 people lined the streets of the city to welcome Bean and his crewmates, dumping a blizzard of ticker tape and shredded office paper on the astronauts and their families during the parade. City workers cleared an estimated 60 tons of paper from the streets after the event.

Workers place the Spacecraft Lunar Module Adapter over the Apollo 13 Lunar Module. On Dec. 10, 1969, NASA announced the selection of the Fra Mauro region of the Moon as the prime landing site for Apollo 13, located about 110 miles east of the Apollo 12 touchdown point. Geologists favored the Fra Mauro area for exploration because it forms an extensive geologic unit around Mare Imbrium, the largest lava plain on the Moon. Unlike the Apollo 11 and 12 sites located in the flat lunar maria, Fra Mauro rests in the relatively more rugged lunar highlands. The precision landing by the Apollo 12 crew and their extensive orbital photography of the Fra Mauro region gave NASA confidence to attempt a landing at Fra Mauro. Workers in KSC’s VAB had stacked the three stages of Apollo 13’s Saturn V in June and July 1969. On Dec. 10, they topped the rocket with the Apollo 13 spacecraft, comprising the Command and Service Modules (CSM) and the Lunar Module (LM) inside the Spacecraft LM Adapter. Five days later, the Saturn V exited the VAB and made the 3.5-mile journey out to Launch Pad 39A to begin a series of tests to prepare it for the launch of the planned 10-day lunar mission. During their 33.5 hours on the Moon’s surface, Lovell and Haise planned to conduct two four-hour spacewalks to set up the ALSEP, a suite of five investigations designed to collect data about the lunar environment after the astronauts’ departure, and to conduct geologic explorations of the landing site. Mattingly planned to remain in the CSM, conducting geologic observations from lunar orbit including photographing potential future landing sites. Apollo 13 astronaut James A. Lovell trains on the deployment of the S-band antenna. Apollo 13 astronaut Fred W. Haise examines one of the lunar surface instruments. During the first of the two spacewalks, Apollo 13 Moon walkers Lovell and Haise planned to deploy the five ALSEP experiments, comprising: Charged Particle Lunar Environment Experiment (CPLEE) – flying for the first time, this experiment sought to measure the particle energies of protons and electrons reaching the lunar surface from the Sun. Lunar Atmosphere Detector (LAD) – this experiment used a Cold Cathode Ion Gauge (CCIG) to measure the pressure of the tenuous lunar atmosphere. Lunar Heat Flow Experiment (LHE) – designed to measure the steady-state heat flow from the Moon’s interior. Passive Seismic Experiment (PSE) – similar to the device left on the Moon during Apollo 12, consisted of a sensitive seismometer to record Moon quakes and other seismic activity. Lunar Dust Detector (LDD) – measured the amount of dust deposited on the lunar surface. A Central Station provided command and communications to the ALSEP experiments, while a Radioisotope Thermoelectric Generator using heat from the radioactive decay of a Plutonium-238 sample provided uninterrupted power. Additionally, the astronauts planned to deploy and retrieve the Solar Wind Collector experiment to collect particles of the solar wind, as did the Apollo 11 and 12 crews before them.

Apollo 13 astronauts Lovell, Haise, Young, and Duke participated in a geology training field trip between Dec. 17 and 20 on the Big Island of Hawaii. Geologist Patrick D. Crosland of the National Park Service in Hawaii provided the astronauts with a tour of recent volcanic eruption sites in the Kilauea area, with the thought that the Fra Mauro formation might be of volcanic origin. During several traverses in the Kilauea Volcano area, NASA geologists John W. Dietrich, Uel S. Clanton, and Gary E. Lofgren and US Geological Survey geologists Gordon A. “Gordie” Swann, M.H. “Tim” Hait, and Leon T. “Lee” Silver accompanied the astronauts. The training sessions honed the astronauts’ geology skills and refined procedures for collecting rock samples and for documentary photography.

At the time tentatively planned for launch in July 1970, mission planners considered the Littrow area on the eastern edge of the Mare Serenitatis, characterized by dark material possibly of volcanic origin, as a potential landing site. Apollo 14 astronauts Commander Alan B. Shepard, CMP Stuart A. Roosa, and LMP Edgar D. Mitchell and their backups Eugene A. Cernan, Ronald E. Evans, and Joe H. Engle had already begun training for their mission. At KSC’s Manned Spacecraft Operations Building (MSOB), the Apollo 14 CSM arrived from its manufacturer North American Rockwell in Downey, California, as did the two stages of the LM from the Grumman Aerospace and Engineering Company in Bethpage, New York, in November 1969. Engineers began tests of the spacecraft shortly after their arrival. The three stages of the Apollo 14 Saturn V were scheduled to arrive at KSC in January 1970.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A digital rendering of the completed Axiom Station, which includes the Payload, Power, and Thermal Module, Habitat 1, an airlock, Habitat 2, and the Research and Manufacturing Facility.Credits: Axiom Space In coordination with NASA, Axiom Space modified its planned assembly sequence to accelerate its ability to operate as a viable free-flying space station and reduce International Space Station reliance during assembly. NASA awarded Axiom Space a firm-fixed price, indefinite-delivery, indefinite-quantity contract in January 2020, as the agency continues to open the space station for commercial use. The contract provides insight into the development of at least one habitable commercial module to be attached to the space station with the goal of becoming a free-flying destination in low Earth orbit prior to retirement of the orbiting laboratory in 2030. The initial Axiom Space plan was to launch and attach its first module, Habitat 1, to the space station, followed by three additional modules. Under the company’s new assembly sequence, the Payload, Power, and Thermal Module will launch to the orbiting laboratory first, allowing it to depart as early as 2028 and become a free-flying destination known as Axiom Station. In free-flight, Axiom Space will continue assembly of the commercial destination, adding the Habitat 1 module, an airlock, Habitat 2 module, and the Research and Manufacturing Facility. “The updated assembly sequence has been coordinated with NASA to support both NASA and Axiom Space needs and plans for a smooth transition in low Earth orbit,” said Angela Hart, manager, Commercial Low Earth Orbit Development Program at NASA’s Johnson Space Center in Houston. “The ongoing design and development of commercial destinations by our partners is critical to the agency’s plan to procure services in low Earth orbit to support our needs in microgravity.” The revised assembly sequence will enable an earlier departure from the space station, expedite Axiom Station’s ability to support free-flight operations, and ensure the orbiting laboratory remains prepared for the U.S. Deorbit Vehicle and end of operational life no earlier than 2030. “The International Space Station has provided a one-of-a-kind scientific platform for nearly 25 years,” said Dana Weigel, manager, International Space Station Program at NASA Johnson. “As we approach the end of space station’s operational life, it’s critically important that we look to the future of low Earth orbit and support these follow-on destinations to ensure we continue NASA’s presence in microgravity, which began through the International Space Station.” NASA is supporting the design and development of multiple commercial space stations, including Axiom Station, through funded and unfunded agreements. The current design and development phase will be followed by the procurement of services from one or more companies. NASA’s low Earth orbit microgravity strategy builds on the agency’s extensive human spaceflight experience to advance future scientific and exploration goals. As the International Space Station nears the end of operations, NASA plans to transition to a new low Earth orbit model to continue leveraging microgravity benefits. Through commercial partnerships, NASA aims to maintain its leadership in microgravity research and ensure continued benefits for humanity.

A rendering of Firefly’s Blue Ghost lunar lander and a rover developed for the company’s third mission to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative.Credit: Firefly Aerospace NASA continues to advance its campaign to explore more of the Moon than ever before, awarding Firefly Aerospace $179 million to deliver six experiments to the lunar surface. This fourth task order for Firefly will target landing in the Gruithuisen Domes on the near side of the Moon in 2028. As part of the agency’s broader Artemis campaign, Firefly will deliver a group of science experiments and technology demonstrations under NASA’s CLPS initiative, or Commercial Lunar Payload Services, to these lunar domes, an area of ancient lava flows, to better understand planetary processes and evolution. Through CLPS, NASA is furthering our understanding of the Moon’s environment and helping prepare for future human missions to the lunar surface, as part of the agency’s Moon to Mars exploration approach. “The CLPS initiative carries out U.S. scientific and technical studies on the surface of the Moon by robot explorers. As NASA prepares for future human exploration of the Moon, the CLPS initiative continues to support a growing lunar economy with American companies,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “Understanding the formation of the Gruithuisen Domes, as well as the ancient lava flows surrounding the landing site, will help the U.S. answer important questions about the lunar surface.” Firefly’s first lunar delivery is scheduled to launch no earlier than mid-January 2025 and will land near a volcanic feature called Mons Latreille within Mare Crisium, on the northeast quadrant of the Moon’s near side. Firefly’s second lunar mission includes two task orders: a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side and a delivery of a lunar orbital calibration source, scheduled in 2026. This new delivery in 2028 will send payloads to the Gruithuisen Domes and the nearby Sinus Viscositatus. The Gruithuisen Domes have long been suspected to be formed by a magma rich in silica, similar in composition to granite. Granitic rocks form easily on Earth due to plate tectonics and oceans of water. The Moon lacks these key ingredients, so lunar scientists have been left to wonder how these domes formed and evolved over time. For the first time, as part of this task order, NASA also has contracted to provide “mobility,” or roving, for some of the scientific instruments on the lunar surface after landing. This will enable new types of U.S. scientific investigations from CLPS. “Firefly will deliver six instruments to understand the landing site and surrounding vicinity,” said Chris Culbert, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston. “These instruments will study geologic processes and lunar regolith, test solar cells, and characterize the neutron radiation environment, supplying invaluable information as NASA works to establish a long-term presence on the Moon.” The instruments, collectively expected to be about 215 pounds (97 kilograms) in mass, include: Lunar Vulkan Imaging and Spectroscopy Explorer, which consists of two stationary and three mobile instruments, will study rocks and regoliths on the summit of one of the domes to determine their origin and better understand geologic processes of early planetary bodies. The principal investigator is Dr. Kerri Donaldson Hanna of the University of Central Florida, Orlando. Heimdall is a flexible camera system that will be used to take pictures of the landing site from above the horizon to the ground directly below the lander. The principal investigator is Dr. R. Aileen Yingst of the Planetary Science Institute, Tucson, Arizona. Sample Acquisition, Morphology Filtering, and Probing of Lunar Regolith is a robotic arm that will collect samples of lunar regolith and use a robotic scoop to filter and isolate particles of different sizes. The sampling technology will use a flight spare from the Mars Exploration Rover project. The principal investigator is Sean Dougherty of Maxar Technologies, Westminster, Colorado. Low-frequency Radio Observations from the Near Side Lunar Surface is designed to observe the Moon’s surface environment in radio frequencies, to determine whether natural and human-generated activity near the surface interferes with science. The project is headed up by Natchimuthuk Gopalswamy of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Photovoltaic Investigation on the Lunar Surface will carry a set of the latest solar cells for a technology demonstration of light-to-electricity power conversion for future missions. The experiment will also collect data on the electrical charging environment of the lunar surface using a small array of solar cells. The principal investigator is Jeremiah McNatt from NASA’s Glenn Research Center in Cleveland. Neutron Measurements at the Lunar Surface is a neutron spectrometer that will characterize the surface neutron radiation environment, monitor hydrogen, and provide constraints on elemental composition. The principal investigator is Dr. Heidi Haviland of NASA’s Marshall Spaceflight Center in Huntsville, Alabama. Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry. Two upcoming CLPS flights scheduled to launch in early 2025 will deliver NASA payloads to the Moon’s near side and south polar region, respectively.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) LISTER (Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity) is one of 10 payloads flying aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative. The instrument is equipped with a drilling system and thermal probe designed to dig into the lunar surface. Photo courtesy: Firefly Aerospace Earth’s nearest neighboring body in the solar system is its Moon, yet to date humans have physically explored just 5% of its surface. It wasn’t until 2023 – building on Apollo-era data and more detailed studies made in 2011-2012 by NASA’s automated GRAIL (Gravity Recovery and Interior Laboratory) mission – that researchers conclusively determined that the Moon has a liquid outer core surrounding a solid inner core. As NASA and its industry partners plan for continued exploration of the Moon under Artemis in preparation for future long-duration missions to Mars, improving our understanding of Earth’s 4.5-billion-year-old Moon will help teams of researchers and astronauts find the safest ways to study and live and work on the lunar surface. That improved understanding is the primary goal of a state-of-the-art science instrument called LISTER (Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity), one of 10 NASA payloads flying aboard the next delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative and set to be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander. Developed jointly by Texas Tech University in Lubbock and Honeybee Robotics of Altadena, California, LISTER will measure the flow of heat from the Moon’s interior. Its sophisticated pneumatic drill will penetrate to a depth of three meters into the dusty lunar regolith. Every half-meter it descends, the drilling system will pause and extend a custom-built thermal probe into the lunar regolith. LISTER will measure two different aspects of heat flow: thermal gradient, or the changes in temperature at various depths, and thermal conductivity, or the subsurface material’s ability to let heat pass through it. “By making similar measurements at multiple locations on the lunar surface, we can reconstruct the thermal evolution of the Moon,” said Dr. Seiichi Nagihara, principal investigator for the mission and a geophysics professor at Texas Tech. “That will permit scientists to retrace the geological processes that shaped the Moon from its start as a ball of molten rock, which gradually cooled off by releasing its internal heat into space.” Demonstrating the drill’s effectiveness could lead to more innovative drilling capabilities, enabling future exploration of the Moon, Mars, and other celestial bodies.. The science collected by LISTER aims to contribute to our knowledge of lunar geology, improving our ability to establish a long-term presence on the Moon under the Artemis campaign. Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander.

This article is for students grades 5-8. The Sun is the star of our solar system. Its gravity holds Earth and our planetary neighbors in its orbit. At 865,000 miles (1.4 million km) in diameter, it’s the largest object in our solar system. On Earth, its influence is felt in our weather, seasons, climate, and more. Let’s learn about our dynamic star and its connections to life on Earth. What is the Sun, and what is it made of? The Sun is a yellow dwarf star. It is approximately 4.5 billion years old and is in its “main sequence” phase. This means it is partway through its lifecycle with a few billion more years ahead of it. The Sun is made of hydrogen and helium gases. At its core, hydrogen is fused to form helium. This nuclear reaction creates the Sun’s heat and light. That energy moves outward through the Sun’s radiative zone and convective zone. It then reaches the Sun’s visible surface and lower atmosphere, called the photosphere. Above the photosphere lies the chromosphere, which forms the Sun’s middle atmosphere, and beyond that is the corona, the Sun’s outermost atmosphere. The Sun is a yellow dwarf star with a complex series of layers and features.NASA What is the solar cycle? The Sun goes through a pattern of magnetic activity known as the solar cycle. During each cycle, the Sun experiences a very active period called “solar maximum” and a less active period called “solar minimum.” During solar maximum, increased magnetic activity creates sunspots. These appear as darker, cooler spots on the Sun’s surface. The more sunspots we can see, the more active the Sun is. The solar cycle begins at solar minimum, peaks at solar maximum, and then returns to solar minimum. This cycle is driven by the Sun’s magnetic polarity, which flips – north becomes south, and vice versa – every 11 years. It takes two cycles – or 22 years – to complete the full magnetic cycle where the poles return to their original positions. The Sun’s level of magnetic activity changes throughout its 11-year solar cycle. During each cycle, the Sun experiences a less-active period called “solar minimum” (left) and a very active period called “solar maximum” (right).NASA Wait. The Sun’s magnetic poles can flip?? Yes! Like Earth, the Sun has north and south magnetic poles. But unlike Earth, the Sun’s poles flip regularly. Each 11-year solar cycle is marked by the flipping of the Sun’s poles. The increased magnetic activity during solar maximum makes the north and south poles less defined. As the cycle moves back to solar minimum, the polarization of the poles returns – with flipped polarity. Unlike Earth, the Sun’s poles regularly flip with each 11-year solar cycle.NASA What is space weather? Space weather includes phenomena such as solar wind, solar storms, and solar flares. When space weather conditions are calm, there may be little noticeable effect on Earth. But when the Sun is more active, space weather has real impacts on Earth and in space. Let’s explore these phenomena and how they affect our planet. Periods of increased solar activity can cause noticeable effects on Earth and in space.NASA What is solar wind? Solar wind is a stream of charged particles that flow outward from the Sun’s corona. It extends far beyond the orbit of the planets in our solar system. When solar wind reaches Earth, its charged particles interact with Earth’s magnetic field. This causes colorful streams of moving light at Earth’s north and south poles called aurora. Earth’s magnetic field protects our planet from the charged solar particles of the solar wind.NASA What are solar storms, solar flares, and coronal mass ejections? The Sun’s magnetic fields are a tangle of constant motion. These fields twist and stretch to the point that they snap and reconnect. When this magnetic reconnection occurs, it releases a burst of energy that can cause a solar storm. Solar storms can include phenomena such as solar flares or coronal mass ejections. They happen more frequently around the solar maximum of the Sun’s cycle. A solar flare is an intense burst of light and energy from the Sun’s surface. Solar flares tend to happen near sunspots where the Sun’s magnetic fields are strongest. A coronal mass ejection is a massive cloud of material flowing outward from the Sun. These can occur on their own or along with solar flares. The Sun’s magnetic field is strongest near sunspots. These active regions of the Sun’s surface release energy in the form of solar flares and coronal mass ejections like these.NASA How do these phenomena affect Earth? When a solar storm erupts towards Earth, our atmosphere and magnetic field protect us from significant harm. However, some impacts are possible, both on Earth and in space. For example, strong solar storms can cause power outages and radio blackouts. GPS signals can be disrupted. Satellite electronics can be affected. And astronauts working outside of the International Space Station could be exposed to dangerous radiation. NASA monitors and forecasts space weather to protect the safety and health of astronauts and spacecraft. When charged particles from intense solar storms interact with Earth’s magnetic fields, colorful auroras like this one captured in Saskatchewan, Canada, can occur.NASA Learn more about the Sun NASA’s Parker Solar Probe launched in 2018 on the first-ever mission to fly into the Sun’s corona.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Spot the Station app was developed in collaboration with the public through a series of crowdsourcing competitions.NASA In its 25th year of operations, the International Space Station continues to symbolize discovery and cooperation for the benefit of humanity. Since 2012, observers have interacted with the space station through NASA’s Spot the Station website, a web browser-based tool that includes interactive maps for users to track the station and find viewpoints closest to their location. A decade after the website’s release, NASA sought to enhance public access to this capability with a mobile app. NASA released the Spot the Station app on IOS and Android in 2023. As of Dec. 2024, it has more than 770,000 users in 227 countries and territories around the globe, according to Ensemble, who NASA contracts to maintain support of the app. Revamping the Spot the Station experience was more than just an opportunity for NASA to make improvements; it allowed NASA to gather direct input from users by involving them in the development of the new app. Space Operations web and platform lead, Allison Wolff, pitched the idea to publicly crowdsource the app’s development. In 2022, Wolff and her team supported the release of three separate crowdsourcing competitions, where global communities were invited to design key components of the new Spot the Station app. Participants submitted functional designs, including an augmented reality component not offered on the web version and interfaces for screens such as login and sign-up windows. Multiple winners were awarded prizes totaling $8,550 across the three challenges. As the former Innovation Strategist in NASA’s Center of Excellence for Collaborative Innovation, part of the agency’s Prizes, Challenges, and Crowdsourcing program, Wolff was well acquainted with the ingenuity and results that stem from public-private collaborations. “NASA strives to incorporate inclusion and innovation into how we operate. We also collaborate with minds outside the agency because the best ideas can come from very surprising places,” said Wolff. Not only were the winning designs used in the final product, but the development team gained valuable feedback and worldwide perspectives from everyone who participated in the competition. “When you use the power of the crowd and get a consistent message about a component or an interface, that’s a good indicator of what is user-friendly,” said Wolff. Crowdsourcing continues to enhance the app’s functionality, including translating the app into six languages, including Spanish, French, and German, thanks to user contributions. In addition, the app’s code is open source, enabling anyone to modify and use the code for their own projects and support the tool’s growth. NASA will continue to update and improve the app with feedback from the public. Find more opportunities: www.nasa.gov/get-involved/ View the full article

4 Min Read Space Gardens NASA astronaut Kayla Barron with chile peppers in the station’s Advanced Plant Habitat. Credits: NASA Science in Space December 2024 As NASA plans missions to the Moon and Mars, one challenge is figuring out how to provide crew members with enough healthy food. Bringing along a supply for months or even years in space is impractical, and stored food can lose taste and nutritional value. Growing plants in space is one way to help solve this problem. Tending space gardens also has positive psychological effects for crew members, and plants can be part of life support systems that provide services such as producing oxygen and reducing carbon dioxide. Outredgeous romaine lettuce grows inside a laboratory at NASA’s Kennedy Space Center in Florida for preflight testing of Plant Habitat-07.NASA A current investigation, Plant Habitat-07, looks at how plants and their associated communities of microorganisms respond to different levels of water. The study uses ‘Outredgeous’ red romaine lettuce, a food crop already known to grow well on the International Space Station. Results from this investigation could inform ways to produce healthy crops under different water conditions in space and on Earth. Multiple studies of plants on the space station have tested a wide range of crops and methods for growing them. Researchers have successfully grown lettuces, Chinese cabbage, mustard greens, kale, tomatoes, radishes, and chile peppers in space. Here are details on results from earlier plant studies. Better lighting NASA astronaut Nick Hague harvests Mizuna mustard greens for VEG-04.NASA The Veg-04A and Veg-04B investigations looked at the effects of light quality and fertilizer on plant growth in space. Researchers found differences in yield and nutritional content depending on how leafy greens are grown and harvested – including choice of light spectrum (red versus blue), a consideration for design of future plant growth facilities. It’s in their genes Arabidopsis thaliana plants grow in the type of nutrient gel Petri plate used for APEX-04. Anna-Lisa Paul, University of Florida APEX-04 studied molecular changes in thale cress seedlings. Researchers found differences in the expression of specific genes in the root systems of the plants, including two genes not previously known to influence root development. This finding could identify ways to genetically modify plants to grow better on future long-duration missions. European Modular Cultivation System Seed Cassettes used for the Plant RNA Regulation investigation.NASA Plant Signaling, a NASA investigation conducted in cooperation with ESA (European Space Agency), studied the effects of various gravity levels on plant seedlings, and Plant RNA Regulation compared gene expression involved in the development of roots and shoots in microgravity and simulated 1 g (Earth’s gravity). Both investigations used the European Modular Cultivation System, a centrifuge that creates 1 g in space and makes it possible to examine the effects of partial gravity. The investigations found increases in the expression of some genes, such as those involved in light response, and decreases in expression of others, including defense response. These findings can help inform design of space-based plant growth facilities. And in their hormones Auxins are plant hormones that affect processes such as root growth. Gravity affects the abundance of these hormones and their movement within a plant. Auxin Transport, an investigation from JAXA (Japan Aerospace Exploration Agency), examined the role of auxins in controlling growth of pea and maize seedlings in microgravity. Researchers found that microgravity caused decreases in hormones involved in determining direction of growth in pea seedlings and increases of those same hormones in maize seedlings. Understanding how microgravity affects plant hormonal pathways could hep improve the design of space-based plant growth systems. Growth and gravity Plant development on Earth is strongly influenced by gravity, but exactly how that works at the molecular level is not well understood. APEX-03-1 investigated the effects of microgravity on plant development and, along with previous studies, showed that spaceflight triggers changes in the development of cell walls in plant roots. Strong cell walls provide mechanical strength needed for roots to grow, and this finding provides insight into how to develop plants that are well-adapted to space conditions. NASA astronaut Karen Nyberg harvests samples for the Resist Tubule investigation.NASA JAXA’s Resist Tubule also studied the mechanisms of gravity resistance in plants. Researchers found that thale cress plants grown in microgravity exhibited reduced levels of sterols, compounds involved in a variety of cellular processes, which could limit plant growth. These findings could help scientists genetically engineer plants that grow better in microgravity.
