Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Curiosity Mars rover sees its tracks receding into the distance at a site nicknamed “Ubajara” on April 30, 2023. This site is where Curiosity made the discovery of siderite, a mineral that may help explain the fate of the planet’s thicker ancient atmosphere.Credit: NASA/JPL-Caltech/MSSS New findings from NASA’s Curiosity Mars rover could provide an answer to the mystery of what happened to the planet’s ancient atmosphere and how Mars has evolved over time.
Researchers have long believed that Mars once had a thick, carbon dioxide-rich atmosphere and liquid water on the planet’s surface. That carbon dioxide and water should have reacted with Martian rocks to create carbonate minerals. Until now, though, rover missions and near-infrared spectroscopy analysis from Mars-orbiting satellites haven’t found the amounts of carbonate on the planet’s surface predicted by this theory.
Reported in an April paper in Science, data from three of Curiosity’s drill sites revealed the presence of siderite, an iron carbonate mineral, within the sulfate-rich rocky layers of Mount Sharp in Mars’ Gale Crater.
“The discovery of abundant siderite in Gale Crater represents both a surprising and important breakthrough in our understanding of the geologic and atmospheric evolution of Mars,” said Benjamin Tutolo, associate professor at the University of Calgary, Canada, and lead author of the paper.
To study the Red Planet’s chemical and mineral makeup, Curiosity drills three to four centimeters down into the subsurface, then drops the powdered rock samples into its CheMin instrument. The instrument, led by NASA’s Ames Research Center in California’s Silicon Valley, uses X-ray diffraction to analyze rocks and soil. CheMin’s data was processed and analyzed by scientists at the Astromaterials Research and Exploration Science (ARES) Division at NASA’s Johnson Space Center in Houston.
“Drilling through the layered Martian surface is like going through a history book,” said Thomas Bristow, research scientist at NASA Ames and coauthor of the paper. “Just a few centimeters down gives us a good idea of the minerals that formed at or close to the surface around 3.5 billion years ago.”
The discovery of this carbonate mineral in rocks beneath the surface suggests that carbonate may be masked by other minerals in near-infrared satellite analysis. If other sulfate-rich layers across Mars also contain carbonates, the amount of stored carbon dioxide would be a fraction of that needed in the ancient atmosphere to create conditions warm enough to support liquid water. The rest could be hidden in other deposits or have been lost to space over time.
In the future, missions or analyses of other sulfate-rich areas on Mars could confirm these findings and help us better understand the planet’s early history and how it transformed as its atmosphere was lost.
Curiosity, part of NASA’s Mars Exploration Program (MEP) portfolio, was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington.

4 Min Read Science Meets Art: NASA Astronaut Don Pettit Turns the Camera on Science
NASA astronaut Don Pettit is scheduled to return home in mid-April after a seven-month mission aboard the International Space Station as part of Expedition 72. Throughout his stay, Pettit contributed to research that benefits humanity and future space missions.
Pettit also shared what he calls “science of opportunity” to demonstrate how experimenting with our surroundings can help gain a better understanding of how things work. This understanding is perhaps enhanced when art, science, and microgravity come together.
Electrostatic Displays
NASA astronaut Don Pettit demonstrates electrostatic forces using charged water droplets and a knitting needle made of Teflon. This series of overlapping frames displays the unique attraction-repulsion properties of Teflon and charged droplets, similar to how charged particles from the Sun behave when they come in contact with Earth’s magnetic field. Highly energetic particles from space that collide with atoms and molecules in the atmosphere create the aurora borealis.
Specialized Equipment for Superb Science
NASA astronaut Don Pettit snaps an image of the hands of NASA astronauts Nick Hague, left, and Suni Williams inside the Life Science Glovebox, a facility at the International Space Station that separates the science from the scientists, thus protecting both from contamination.
The freezers on the International Space Station are as crucial as its experiment modules, preserving samples for further analysis on Earth. The Minus Eighty-Degree Laboratory Freezer for International Space Station stores samples at ultra-cold temperatures. NASA astronaut Don Pettit used it to freeze thin ice wafers, which he photographed with a polarizing filter to reveal unique crystal structures.
New Tech Roll-Out
NASA astronaut Don Pettit films a time-lapse sequence of Canadarm2 retrieving Materials International Space Station Experiment (MISSE-20-Commercial) samples at the International Space Station. This investigation exposed various experiments to the harsh space environment, such as vacuum, radiation, and extreme temperatures. Findings could help in many areas, from designing more durable materials to advancing quantum communications.
A surge in International Space Station research supports NASA’s exploration efforts at the Moon and beyond, requiring more energy to operate the orbiting laboratory. NASA astronaut Don Pettit photographs new and old solar arrays side by side. The technology used by the International Space Station Roll-Out Solar Arrays (IROSA) on the right was first tested aboard the station in 2017. By 2023, six IROSAs were deployed aboard station, providing a 20-30% increase in power for research and operations. Roll-Out Solar Arrays were also used on NASA’s DART asteroid mission and now are slated for the Gateway lunar outpost, a vital component of Artemis.
Squire for Spacewalks
I am the nameless boy who stays in the confines of the tent helping the Knights suit up for battle. I remain in the airlock, preparing these knights for a walk outside.
Don Pettit
"Space Squire" posted to X
NASA astronaut Don Pettit helped his colleagues suit up for two spacewalks in January. The first spacewalk involved patching the Neutron Star Interior Composition Explorer (NICER), a telescope that measures X-rays from neutron stars and other cosmic objects. Sunlight interference affected data collection, and the patches reduced this issue. On the second spacewalk, astronauts collected samples from the exterior of the International Space Station for ISS External Microorganisms. This investigation examines whether the orbiting laboratory releases microbes, how many, and how far these may travel. Findings could inform the design of future spacecraft, including spacesuits, to limit biocontamination during future space missions.
Photography with a Spin
NASA astronaut Don Pettit photographs “cosmic colors at sunrise.” From 250 miles above, the International Space Station’s orbital path covers most of Earth’s population, offering valuable data and a great opportunity for shooting breathtaking photography.
NASA astronaut Don Pettit leveraged his stay aboard the International Space Station to photograph our planet with an artistic twist.
NASA astronaut Don Pettit wrote on social media about his snapshot of the Mediterranean Sea from the International Space Station, “Sun glint off the Mediterranean Sea (infrared and converted to black and white). When the Sun reflects off the ocean, watery details unseen with normal lighting appear. Small centimeter differences in ocean height become visible, revealing hidden currents.”
NASA astronaut Don Pettit’s photography could contribute to the study of transient luminous events, colorful electrical discharges that occur above thunderstorms. His imagery can be paired with data from the Atmosphere-Space Interactions Monitor (ASIM) and Thor-Davis, a high-speed thunderstorm camera. The combined efforts of crew photography and instruments aboard the International Space Station help scientists better understand thunderstorms and their impacts on Earth’s upper atmosphere.
More of Pettit’s photography can be found on his X profile, @astro_Pettit.

What Does NASA Science Do For Me?
It is easy to forget that all of the hard work, technology, and money that NASA pours into space research actually comes back down to Earth. In fact, many of NASA’s missions and research focus on our planet! NASA also has many other projects with partners that use their research to enrich everyone’s lives here on Earth- and this is not including such notable achievements as satellite weather maps!
The NASA Spinoff program was created over fifty years ago to facilitate the licensing and development of NASA’s technologies for commercial use by other companies and agencies. This program helps “spin off” NASA’s technology for use by others here on Earth and, in some cases, in space. To date, over 2,000 spinoff technologies have been documented by the NASA Spinoff program.
Some notable examples of NASA spinoffs include:
Solar Cells Water Purification Memory foam for your cozy bed and chairs Firefighting equipment, especially lightweight fireproof clothing and masks with much-improved air filters Highway safety grooves, which help your car go around curves without slipping off by giving your tire better traction Many safety features in modern aircraft, such as de-icing technologies for wings, chemical detectors and imaging for plane maintenance, improved flight controls, and many more Image stabilization for your binoculars and video cameras The Dustbuster Healthier baby food …and many more! Check out this Wikipedia page for a more extensive list of the technologies that NASA has had a direct role in developing, many of which we now take for granted.
It is worth noting that there are a few technologies commonly thought to have been created by NASA that were actually independently developed. Tang is a great example; it was developed by General Foods in 1957 and attained fame when used during food testing by NASA in the 60s (even though some astronauts were not fans of the powdery, not-quite-orange juice). The microwave oven is another famous technology often falsely thought of as a NASA development. It was, in fact, created shortly after World War 2, when radar technicians discovered that it wasn’t such a good idea to stand in front of active equipment! Thankfully, they found out via a melted candy bar and not from severe burns!
Every year, NASA releases a report on its program, and the 2025 edition of the NASA Spinoff magazine is now available! You can view the entire NASA Spinoff archive, dating back to 1976, here.

More than 500 students with 75 teams from around the world participated in the 31st year of the competition. Participating teams represented 35 colleges and universities, 38 high schools, and two middle schools from 20 states, Puerto Rico, and 16 other nations. Teams were awarded points based on navigating a half-mile obstacle course, conducting mission-specific task challenges, and completing multiple safety and design reviews with NASA engineers.
NASA expanded the 2025 challenge to include a remote-control division, Remote-Operated Vehicular Research, and invited middle school students to participate.
“This student design challenge encourages the next generation of scientists and engineers to engage in the design process by providing innovative concepts and unique perspectives,” said Vemitra Alexander, who leads the challenge for NASA’s Office of STEM Engagement at Marshall. “This challenge also continues NASA’s legacy of providing valuable experiences to students who may be responsible for planning future space missions, including crewed missions to other worlds.”
The rover challenge is one of NASA’s eight Artemis Student Challenges reflecting the goals of the Artemis campaign, which will land Americans on the Moon while establishing a long-term presence for science and exploration, preparing for future human missions to Mars. NASA uses such challenges to encourage students to pursue degrees and careers in the fields of science, technology, engineering, and mathematics.
The competition is managed by NASA’s Southeast Regional Office of STEM Engagement at Marshall. Since its inception in 1994, more than 15,000 students have participated – with many former students now working at NASA, or within the aerospace industry.
