Preparations for Next Moonwalk Simulations Underway (and Underwater)
A group of middle school students engage with a model aircraft while learning from NASA experts in the model lab at NASA’s Armstrong Flight Research Center in Edwards, California during an event hosted by NASA’s California Office of STEM Engagement.NASA/Steve Freeman In celebration of National Aviation History Month, experts from NASA’s Armstrong Flight Research Center in Edwards, California, spoke with middle school students during a recent event hosted by NASA’s California Office of STEM Engagement. NASA Armstrong employees shared stories about the center’s role in aviation history and current research projects while also talking about their own paths to working at NASA. During the virtual and in-person event on Nov. 6, Southern California middle school students were presented with the importance of pursing their passions, the value of internships and exploring diverse career opportunities within NASA.
Kicking off the event, NASA Armstrong Center Director Brad Flick talked about his journey from a small town to becoming a NASA engineer. “I never, in my wildest dreams thought I had the opportunity to work for someplace like NASA,” Flick said. “I’ve been here for almost 40 years and at a little part of NASA that most people don’t know exists, right? Which is really cool that we’re tying this to aviation history month, because this is one of the places where aviation history has been made, is being made and will continue to be made.” Flick encouraged students to participate in STEAM programs that integrate the arts with science, technology, engineering, and math and stressed the importance of asking questions and being curious.
A panel of four NASA Armstrong experts – Laurie Grindle, deputy center director; Troy Asher, director of Flight Operations; Nicki Reid, lead operations engineer; and Julio Trevino, operations engineer – shared their stories about their career paths and experiences at NASA.

From left to right: Laurie Grindle, Julio Trevino, Nicki Reid and Troy Asher.NASA/Steve Freeman Reid talked about her initial struggle with math and science and how it didn’t stop her from obtaining an engineering degree and applying for internships, which is what ultimately opened the door for her at NASA. “It was a really cool experience because it gives you a chance to decide whether or not you like the job and I got to learn from different people every summer,” Reid said.
Grindle’s dream as a kid was to become an astronaut and although did not happen for her, her interest in aviation and space continued, which ultimately led to working at NASA as a student. “I had a lot of different opportunities working in different roles. I had fun while doing it and did a job I really enjoyed that made it not like work,” Grindle said.
For Asher, determination and commitment helped him become a pilot. “I remember sitting in the back seat of the airplane, looking out and thinking, ‘I love this. I’m doing this forever,’” Asher said. “But it took me five or six years before I had that moment, and it was the commitment the kept me going.”

Students also received tours around the center with stops in the model lab, life support office and control room.
“This was a wonderful opportunity for my seventh-grade students to learn more about careers and career paths in NASA,” said Shauna Tinich, Tropico Middle School teacher. “They were surprised that people other than astronauts and rocket scientists work for NASA, and this excited many of my students.”
NASA’s California Office of STEM Engagement collaborates with the regional STEM community to provide opportunities like these, with the support of Next Gen STEM, to help students in sparking their interest and inspiring the next generation of leaders.

NASA’s Human Landing System (HLS) will transport the next astronauts that land on the Moon, including the first woman and first person of color, beginning with Artemis III. For safety and mission success, the landers and other equipment in development for NASA’s Artemis campaign must work reliably in the harshest of environments.
The Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) lab at NASA’s Marshall Space Flight Center in Huntsville, Alabama, provides engineers with thermal analysis of materials that may be a prototype or in an early developmental stage using a vacuum chamber, back left, and a conduction chamber, right. NASA/Ken Hall Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are currently testing how well prototype insulation for SpaceX’s Starship HLS will insulate interior environments, including propellant storage tanks and the crew cabin. Starship HLS will land astronauts on the lunar surface during Artemis III and Artemis IV.
Marshall’s Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) laboratory provides the resources and tools for an early, quick-check evaluation of insulation materials destined for Artemis deep space missions.
“Marshall’s HI-TTeMP lab gives us a key testing capability to help determine how well the current materials being designed for vehicles like SpaceX’s orbital propellant storage depot and Starship HLS, will insulate the liquid oxygen and methane propellants,” said HLS chief engineer Rene Ortega. “By using this lab and the expertise provided by the thermal engineers at Marshall, we are gaining valuable feedback earlier in the design and development process that will provide additional information before qualifying hardware for deep space missions.”
A peek inside the conductive test chamber at NASA Marshall’s HI-TTeMP lab where thermal engineers design, set up, execute, and analyze materials destined for deep space to better understand how they will perform in the cold near-vacuum of space. NASA/Ken Hall On the Moon, spaceflight hardware like Starship HLS will face extreme temperatures. On the Moon’s south pole during lunar night, temperatures can plummet to -370 degrees Fahrenheit (-223 degrees Celsius). Elsewhere in deep space temperatures can range from roughly 250 degrees Fahrenheit (120 degrees Celsius) in direct sunlight to just above absolute zero in the shadows.
There are two primary means of managing thermal conditions: active and passive. Passive thermal controls include materials such as insulation, white paint, thermal blankets, and reflective metals. Engineers can also design operational controls, such as pointing thermally sensitive areas of a spacecraft away from direct sunlight, to help manage extreme thermal conditions. Active thermal control measures that could be used include radiators or cryogenic coolers.
Engineers use two vacuum test chambers in the lab to simulate the heat transfer effects of the deep space environment and to evaluate the thermal properties of the materials. One chamber is used to understand radiant heat, which directly warms an object in its path, such as when heat from the Sun shines on it. The other test chamber evaluates conduction by isolating and measuring its heat transfer paths.
NASA engineers working in the HI-TTeMP lab not only design, set up, and run tests, they also provide insight and expertise in thermal engineering to assist NASA’s industry partners, such as SpaceX and other organizations, in validating concepts and models, or suggesting changes to designs. The lab is able to rapidly test and evaluate design updates or iterations.
NASA’s HLS Program, managed by NASA Marshall, is charged with safely landing astronauts on the Moon as part of Artemis. NASA has awarded contracts to SpaceX for landing services for Artemis III and IV and to Blue Origin for Artemis V. Both landing services providers plan to transfer super-cold propellant in space to send landers to the Moon with full tanks.
With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of Mars. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the HLS, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

Sols 4368-4369: The Colors of Fall – and Mars
This image shows all the textures — no color in ChemCam remote-imager images, though — that the Martian terrain has to offer. This image was taken by Chemistry & Camera (ChemCam) aboard NASA’s Mars rover Curiosity on Nov. 18, 2024 — sol 4367, or Martian day 4,367 of the Mars Science Laboratory mission — at 02:55:09 UTC. NASA/JPL-Caltech/LANL Earth planning date: Monday, Nov. 18, 2024
I am in the U.K., where we are approaching the time when trees are just branches and twigs. One tree that still has its full foliage is my little quince tree in my front garden. Its leaves have turned reddish-brown with a hint of orange, fairly dark by now, and when I passed it this afternoon on my way to my Mars operations shift, I thought that these leaves have exactly the colors of Mars! And sure enough, today’s workspace is full of bedrock blocks in the beautiful reddish-brown that we love from Mars. But like that tree, it’s not just one color, but many different versions and patterns, all of many reddish-brown and yellowish-brown colors.
The tree theme continues into the naming of our targets today, with ChemCam observing the target “Big Oak Flat,” which is a flat piece of bedrock with a slightly more gray hue to it. “Calaveras,” in contrast, looks a lot more like my little tree, as it is more reddish and less gray. It’s also a bedrock target, and APXS and MAHLI are observing this target, too. APXS has another bedrock target, called “Murphys” on one of the many bedrock pieces around. MAHLI is of course documenting Murphys, too. Let’s just hope that this target name doesn’t get any additions to it but instead returns perfect data from Mars!
ChemCam is taking several long-distance remote micro-imager images — one on the Gediz Vallis Ridge, and one on target “Mono Lake,” which is also looking at the many, many different textures and stones in our surroundings. The more rocks, the more excited a team of geologists gets! So, we are surely using every opportunity to take images here!
Talking about images… Mastcam is taking documentation images on the Big Oak Flat and Calaveras targets, and a target simply called “trough.” In addition, there are mosaics on “Basket Dome” and “Chilkoot,” amounting to quite a few images of this diverse and interesting terrain! More images will be taken by the navigation cameras for the next drive — and also our Hazcam. We rarely talk about the Hazcams, but they are vital to our mission! They look out from just under the rover belly, forward and backward, and have the important task to keep our rover safe. The forward-looking one is also great for planning purposes, to know where the arm can reach with APXS, MAHLI, and the drill. To me, it’s also one of the most striking perspectives, and shows the grandeur of the landscape so well. If you want to see what I am talking about, have a look at “A Day on Mars” from January of this year.
Of course, we have atmospheric measurements in the plan, too. The REMS sensor is measuring temperature and wind throughout the plan, and Curiosity will be taking observations to search for dust devils, and look at the opacity of the atmosphere. Add DAN to the plan, and it is once again a busy day for Curiosity on the beautifully red and brown Mars. And — hot off the press — all about another color on Mars: yellowish-white!

Video: 00:04:30 Explore the immense power of water as ESA’s Mars Express takes us on a flight over curving channels, streamlined islands and muddled ‘chaotic terrain’ on Mars, soaking up rover landing sites along the way.
This beautiful flight around the Oxia Palus region of Mars covers a total area of approximately 890 000 km2, more than twice the size of Germany. Central to the tour is one of Mars’s largest outflow channels, Ares Vallis. It stretches for more than 1700 km2 and cascades down from the planet’s southern highlands to enter the lower-lying plains of Chryse Planitia.
Billions of years ago, water surged through Ares Vallis, neighbouring Tiu Vallis, and numerous other smaller channels, creating many of the features observed in this region today.
Enjoy the flight!
After enjoying a spectacular global view of Mars we focus in on the area marked by the white rectangle. Our flight starts over the landing site of NASA’s Pathfinder mission, whose Sojourner rover explored the floodplains of Ares Vallis for 12 weeks in 1997.
Continuing to the south, we pass over two large craters named Masursky and Sagan. The partially eroded crater rim of Masursky in particular suggests that water once flowed through it, from nearby Tiu Vallis.
The Masurky Crater is filled with jumbled blocks, and you can see many more as we turn north to Hydaspis Chaos. This ‘chaotic terrain’ is typical of regions influenced by massive outflow channels. Its distinctive muddled appearance is thought to arise when subsurface water is suddenly released from underground to the surface. The resulting loss of support from below causes the surface to slump and break into blocks of various sizes and shapes.
Just beyond this chaotic array of blocks is Galilaei crater, which has a highly eroded rim and a gorge carved between the crater and neighbouring channel. It is likely that the crater once contained a lake, which flooded out into the surroundings. Continuing on, we see streamlined islands and terraced river banks, the teardrop-shaped island ‘tails’ pointing in the downstream direction of the water flow at the time.
Crossing over Ares Vallis again, the flight brings us to the smoother terrain of Oxia Planum and the planned landing site for ESA’s ExoMars Rosalind Franklin rover. The primary goal of the mission is to search for signs of past or present life on Mars, and as such, this once water-flooded region is an ideal location.
Zooming out, the flight ends with a stunning bird’s-eye view of Ares Vallis and its fascinating water-enriched neighbourhood.

How the movie was made
This film was created using the Mars Express High Resolution Stereo Camera Mars Chart (HMC30) data, an image mosaic made from single orbit observations of the High Resolution Stereo Camera (HRSC). The mosaic, centred at 12°N/330°E, is combined with topography information from the digital terrain model to generate a three-dimensional landscape.
For every second of the movie, 50 separate frames are rendered following a predefined camera path in the scene. A three-fold vertical exaggeration has been applied. Atmospheric effects such as clouds and haze have been added to conceal the limits of the terrain model. The haze starts building up at a distance of 300 km.
The HRSC camera on Mars Express is operated by the German Aerospace Center (DLR). The systematic processing of the camera data took place at the DLR Institute for Planetary Research in Berlin-Adlershof. The working group of Planetary Science and Remote Sensing at Freie Universität Berlin used the data to create the film.

Sols 4366–4367: One of Those Days on Mars (Sulfate-Bearing Unit to the West of Upper Gediz Vallis)
NASA’s Mars rover Curiosity acquired this image using its Right Navigation Camera on Nov. 14, 2024 — sol 4363, or Martian day 4,363 of the Mars Science Laboratory mission – at 02:55:34 UTC. NASA/JPL-Caltech Earth planning date: Friday, Nov. 15, 2024
The Monday plan and drive had executed successfully, so the team had high hopes for APXS and MAHLI data on several enticing targets in the rover’s workspace. Alas, it was not to be: The challenging terrain had resulted in an awkwardly perched wheel at the end of the drive, so we couldn’t risk deploying the arm from this position. Maybe next drive!
We did plan a busy weekend of non-arm science activities regardless. Due to a “soliday” the weekend has two sols instead of three, but we had enough power available to fit in more than three hours of observations. The two LIBS observations in the plan will measure the composition of the flat, reddish material in the workspace that is fractured in a polygonal pattern (“Bloody Canyon”) and a nearby rock coating in which the composition is suspected to change with depth (“Burnt Camp Creek”). One idea is that the reddish material could be the early stage version of the thicker dark coatings we’ve been seeing.
A large Mastcam mosaic (“Yosemite”) was planned to capture the very interesting view to the rover’s north. Nearby and below the rover is the layer of rocks in which the “Mineral King” site was drilled on the opposite side of the channel back in March. This is a stratum of sulfate-bearing rock that appears dark-toned from orbit and we’re interested to know how consistent its features are from one side of the channel to the other. Higher up, the Yosemite mosaic also captures some deformation features that may reveal past water activity, and some terrain associated with the Gediz Vallis ridge. So there’s a lot of science packed into one mosaic!
Two long-distance RMI mosaics were planned; one is to image back into the channel, where there may be evidence of a late-stage debris flow at the base of the ridge. The second looks “forward” from the rover’s perspective instead, into the wind-shaped yardang unit above us that will hopefully be explored close-up in the rover’s future. This yardang mosaic is intended to form one part of a stereo observation.
The modern environment on Mars will also be observed with dust devil surveys on both sols, line-of-sight and tau observations to measure atmospheric opacity (often increased by dust in the atmosphere), and zenith and suprahorizon movies with Navcam to look for clouds. There will also be standard passive observations of the rover’s environment by REMS and DAN.
We’ll continue driving westward and upward, rounding the Texoli butte to keep climbing through the sulfate-bearing unit. It’s not always easy driving but there’s a lot more science to do!
