The Astronomy Activation Ambassadors (AAA) project, part of the NASA Science Activation program, aims to measurably enhance student STEM (Science, Technology, Engineering, & Mathematics) engagement via middle school, high school, and community college science teacher professional development. AAA participants draw on NASA resources and subject matter experts to enhance their teaching and help share their excitement about astronomy and planetary science with their students. An important component of AAA teacher professional development is STEM immersion experiences, including guided tours of working observatories.

Teacher visits to observatories offer a rare chance to connect science with history, culture, and place. Framing those visits around the historical context of astronomy and the cultural significance of “high places” helps students see science as a human endeavor shaped by many voices. People everywhere look to the sky for meaning and knowledge, and mountain peaks often carry spiritual, cultural, and historical weight for local communities. The significance of these locations can be shared with their students.

AAA STEM immersion experiences took place in Hilo, Hawaii, and Tucson, Arizona, respectively, in April and September 2025. During the weekend of April 12-13, 16 teachers from across the state of Hawai`i gathered in Hilo for a full agenda involving a hands-on electromagnetic spectrum and multiwavelength astronomy curriculum workshop, subject matter expert presentations regarding astronomy research and native Hawaiian perspectives on Maunakea, and a visit to the summit of Maunakea (Figures 1 & 2). Teacher participants expressed their appreciation especially for the summit visit portion of the workshop and had numerous discussions during the journey about ways they could incorporate this content into their teaching.

The tour paused on the way up the mountain at the mid-level Onizuka Visitors Center. There, workshop participant, local high school teacher, and native Hawaiian cultural practitioner Toni Kaui addressed the group: “Standing here, we have passed through the wao kele (vah-oh kay-lay; forested uplands) and are about to enter the wao akua (vah-oh ah-koo-ah), the heavenly realm where our spirits and our elements of sacredness lie. […] This is where we come to have our spiritual connection with the mauna (mountain). In the wao akua, all of our sacred and elemental processes happen, and those processes help to determine the well-being of our ‘aina (-eye-nah; homeland) down below in the wao kanaka (vah-oh kah-nah-kah; human realm) where we came from.”

The Maunakea visit was recorded by the NASA Science Activation program’s Infiniscope (Arizona State University) team, who joined AAA in the production of a virtual (video) tour highlighting both native Hawaiian and scientific researcher respect for the mountain. The virtual tour will be placed in the Infiniscope library (https://infiniscope.org) to be shared with a world-wide public audience.

The AAA program’s final workshop and STEM immersion experience was offered September 13-14 to 25 teachers from throughout the U.S. at the National Science Foundation’s NOIRLab headquarters in Tucson, Arizona and at Kitt Peak National Observatory (Figure 3).

Kitt Peak National Observatory is located within the land of the Tohono O’odham (tuh-hoh-noh aw-tuhm) Native American tribe, whose name for Kitt Peak is I’oligam Du’ag (ee-oh-lih-gahm doo-ahg), meaning “Manzanita Shrub Mountain”. Dr. Jacelle Ramon-Sauberan, Tohono Oʼodham Education Development Liaison with the NOIRLab, spoke with workshop participants regarding the long history of productive collaboration between local indigenous authorities and organizations developing and managing astronomy facilities on the mountain (Figure 4). She noted that the lease agreement between the Tohono O’odham nation and the NSF: “… is in perpetuity, as long as the mountain is used for astronomical study and research/education.” The AAA participant teachers found Dr. Ramon-Sauberan so inspiring that they enthusiastically gave up part of their scheduled lunch hour so she could have more time for her presentation.

The AAA project is winding down operations after 10 years as an active part of the NASA Science Activation’s collective efforts. In 2025, the ensemble of SciAct projects reached millions of learners in the U.S. and around the world via web-based content, public events, and education resources. As of the end of 2025, the AAA project alone had 780 teacher participants in 46 U.S. states plus 10 countries; 420 teachers have received STEM immersion experiences including flights on NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) or visits to ground-based observatories. An estimated 70,000 students nation-wide have been influenced and inspired by AAA educators.

Participant or Team Member Quotes

Lillian Reynolds, Hawai`i middle school science teacher, stated: “I was fortunate to go to this STEM experience at Maunakea. One thing that I learned is about how many other jobs and people it takes to run all the telescopes and everything up there. I had this preconceived idea that it’s mostly astronomers, PhD people that I didn’t really relate to. I got to meet a lot of the technicians and other folks and that really opened my eyes to other opportunities for my students. So, that’s what I’m looking forward to taking back. It made me feel hopeful that we can really increase our base of home-grown scientists here in Hawai`i.”

Olivia Kuper, Tennessee high school science teacher, noted: “The inclusion of the Indigenous history and perspectives connected to Kitt Peak was one of the most important aspects of the training for me. It reinforced the importance of teaching astronomy in ways that respect the land and the people tied to it. This approach deepened my understanding and will help my students recognize the value of cultural perspectives and historical context in scientific practice.”

NASA and its international partners will receive scientific research samples and hardware when a SpaceX Dragon spacecraft departs the International Space Station on Thursday, Feb. 26, and returns to Earth.

Watch NASA’s live coverage of the undocking and departure of the agency’s 33rd SpaceX Commercial Resupply Services mission starting at 11:45 a.m. EST on NASA+, Amazon Prime, and the agency’s YouTube channel. Learn how to watch NASA content on a variety of online platforms, including social media.

A Dragon spacecraft will autonomously undock from the Harmony module’s forward-facing port at 12:05 p.m. and fire its thrusters to move safely away from the space station. Splashdown is scheduled later that evening at approximately 11:44 p.m. PST off the California coast. NASA will not stream the splashdown but will post updates on its space station blog.

Several scientific investigations are returning aboard Dragon, offering insights that could help shape future space exploration and life on Earth. The Euro Material Ageing study exposed 141 samples to space for a year to examine how coatings, insulation, and 3D-printed materials degrade, while Thailand’s Liquid Crystals experiment observed the stability of films used in electronics in microgravity. Both could lead to stronger spacecraft, better displays, and improved optical devices on future missions.

Frozen samples from the Stellar Stem Cells Mission 2 experiment are helping study how microgravity affects brain and heart stem cell growth, which could improve treatments for diseases such as ALS and Parkinson’s disease. The SpaceDuino project is paving the way for more low-cost instruments after successfully measuring vibrations using a commercially available single-board computer and open-source software. The Moon Microscope also successfully tested a portable diagnostic kit for blood analysis in space that could support future missions to the Moon and Mars.

The Dragon spacecraft supporting the mission also introduced a new capability to reboost the space station, helping maintain its altitude and counter atmospheric drag, which is critical for safe operations and the long-term sustainability of the orbital complex. During its time docked to the station, Dragon performed six reboosts — five in 2025 and a final maneuver on Jan. 23 — before preparations for its departure began.

Loaded with thousands of pounds of crew supplies, science experiments, and equipment, the spacecraft arrived at the station on Aug. 25, 2025, following its launch a day earlier on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies concentrate on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is focusing its resources on deep space missions to the Moon as part of the Artemis campaign in preparation for future astronaut missions to Mars.

Description

NASA’s Curiosity Mars rover discovered these bumpy, pea-sized nodules while exploring a region filled with boxwork formations — low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in-between. This mosaic is made up of 50 individual images taken by Curiosity’s Mars Hand Lens Imager (MAHLI), a camera on the end of the rover’s robotic arm, on Aug. 21, 2025, the 4,636th Martian day, or sol, of the mission. Ten images at different focus settings were taken at each of five locations to produce a sharp mosaic. The images were stitched together after being sent back to Earth.

Figure A is the same image with a small scale bar added to the right-hand side.

Nodules like these have been seen many times before on the Red Planet, including by Curiosity. They were made by minerals left behind as water dried billions of years ago. Crisscrossing the surface for miles, the boxwork formations suggest ancient groundwater flowed on this part of the Red Planet later than expected, raising new questions about how long microbial life could have survived on Mars billions of years ago, before rivers and lakes dried up.

The boxwork ridgetops often include a dark line the team refers to as “central fractures,” where groundwater originally seeped through a rock crack, allowing minerals to concentrate. Surprisingly, the mission did not find nodules near these central fractures. Instead, they were found along the walls of the ridges and in the hollows between them. The wavy ridges between the groups of nodules are mineral veins made of calcium sulfate, also deposited by groundwater.

Curiosity 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 as part of NASA’s Mars Exploration Program portfolio. MAHLI was built by Malin Space Science Systems in San Diego.

Description

NASA’s Curiosity Mars rover captured this panorama of boxwork formations — the low ridges seen here with hollows in between them — using its Mastcam on Sept. 26, 2025, the 4,671st Martian day, or sol, of the mission. These boxwork formations were created billions of years ago when water leaked through rock cracks. Minerals carried into the cracks later hardened; after eons of windblown sand eroding away the softer rock, the hardened ridges were left exposed.

The panorama is made up of 179 individual images that were stitched together after being sent back to Earth. This natural color view is approximately how the scene would appear to an average person if they were on Mars.

For about six months, NASA’s Curiosity Mars rover has been exploring a region full of geologic formations called boxwork, low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. Crisscrossing the surface for miles, the formations suggest ancient groundwater flowed on this part of the Red Planet later than scientists expected. This possibility raises new questions about how long microbial life could have survived on Mars billions of years ago, before rivers and lakes dried up and left a freezing desert world behind.

The boxwork formations look like giant spiderwebs when viewed from space. To explain the shapes, scientists have proposed that groundwater once flowed through large fractures in the bedrock, leaving behind minerals. Those minerals then strengthened the areas that became ridges while other portions without mineral reinforcement were eventually hollowed out by wind.

Until Curiosity arrived at this region, however, no one could be sure what these formations looked like up close, and there were even more questions about how they were made.

Unpacking boxwork

Although Earth also has boxwork ridges, they’re rarely taller than a few centimeters and are usually found in caves or in dry, sandy environments. The Curiosity team wanted to get a close look at the Martian formations and gather more data. This posed a real challenge for rover drivers: They needed to send instructions to Curiosity, an SUV-size vehicle that weighs nearly a ton (899 kilograms), so that it could roll across the tops of ridges not much wider than the rover itself.

“It almost feels like a highway we can drive on. But then we have to go down into the hollows, where you need to be mindful of Curiosity’s wheels slipping or having trouble turning in the sand,” said operations systems engineer Ashley Stroupe of NASA’s Jet Propulsion Laboratory in Southern California, which built Curiosity and leads the mission. “There’s always a solution. It just takes trying different paths.”

For scientists, the challenge is piecing together how such a vast network of boxwork could exist on Mount Sharp, the 3-mile-tall (5-kilometer-tall) mountain the rover has been ascending. Each layer of the mountain formed in a different era of Mars’ ancient, changing climate. The higher Curiosity goes, the more the landscape bears signs that water was drying out over time, with occasional wet periods that saw the return of rivers and lakes.

“Seeing boxwork this far up the mountain suggests the groundwater table had to be pretty high,” said Tina Seeger of Rice University in Houston, one of the mission scientists leading the boxwork investigation. “And that means the water needed for sustaining life could have lasted much longer than we thought looking from orbit.”

Previous orbital imagery included one crucial piece of evidence: dark lines running across the “spiderwebs.” In 2014, it was proposed that these lines might be what are known as central fractures, where groundwater seeped through rock cracks and allowed minerals to concentrate. Investigating the ridges up close, Curiosity found that these lines are in fact fractures, lending weight to that hypothesis.

The rover also discovered bumpy textures called nodules, an obvious sign of past groundwater that has been spotted many times by Curiosity and other Mars missions. Unexpectedly, these nodules were not found near the central fractures, but along a ridge’s walls and the hollows between them.

“We can’t quite explain yet why the nodules appear where they do,” Seeger said. “Maybe the ridges were cemented by minerals first, and later episodes of groundwater left nodules around them.”

Roving laboratory

A major part of Curiosity’s science centers on rock samples collected by the rock-pulverizing drill on the end of the rover’s robotic arm. The resulting powder can be trickled into complex science instruments in the vehicle’s body for analysis.

Last year, three samples from the boxwork region — one from a ridgetop, one from bedrock within a hollow, and one from a transitional area before Curiosity reached the ridges — were collected by the drill and analyzed with X-rays and a high-temperature oven. The X-ray analyses found clay minerals in the ridge and carbonate minerals in the hollow, providing additional clues to help understand how these features formed.

The mission recently collected a fourth sample, which was analyzed with a special technique reserved for the most intriguing science targets: After the pulverized rock went into the rover’s high-temperature oven, chemical reagents reacted with the sample to conduct what is called wet chemistry. The resulting reactions make it easier to detect certain organic compounds, carbon-based molecules important to the formation of life.

Sometime in March, Curiosity will leave the boxwork formations behind. The whole region is part of a layer on Mount Sharp enriched in salty minerals called sulfates, which formed as water was drying out on Mars. Curiosity’s team plans to continue exploring this sulfate layer for many miles in the coming year, learning more about how the ancient Red Planet’s climate changed billions of years ago.
