Following their landmark Artemis II mission earlier this year, distinguished NASA astronauts Victor Glover and Reid Wiseman are transitioning in September to emeritus status at the agency’s Johnson Space Center in Houston.

In an emeritus role, individuals with a high degree of technical and professional knowledge can continue to support the agency by donating their time to train and mentor the current workforce. This allows the agency to maintain access to top talent in a specialized consultant role, while simultaneously providing the individual with the flexibility to pursue other opportunities.

“I’ve had the privilege of knowing Reid and Victor for years, and both exemplify the leadership, character, and commitment that define NASA at its best.” said NASA Administrator Jared Isaacman. “Reid commanded Artemis II after previously spending 165 days aboard the International Space Station, while Victor brought his experience as a naval aviator, test pilot, and Crew-1 astronaut to his role as pilot. Together, they took on one of the most challenging missions in human spaceflight and helped return America to the lunar environment. As Reid and Victor transition to emeritus status, I’m grateful they will continue sharing what they learned with our astronauts, flight controllers, and engineers as we prepare for Artemis III in 2027 and the missions that follow.”

Glover will support aerospace, leadership, and public service efforts as he transitions within and outside of NASA. He’s committed to transferring his knowledge of Orion and its spacecraft systems, among other expertise, to future Artemis missions.

“As I grow into this new role, NASA and spaceflight remain a meaningful part of my journey of service,” said Glover. “I’m excited to keep uplifting my friends and cheering them on as they reach for the Moon. Together, we’ll keep pushing boundaries and inspiring the next giant leap.”

Wiseman is set to share his spaceflight experience with colleagues ahead of the agency’s Artemis III mission in low Earth orbit to test rendezvous and docking capabilities between Orion and commercial human landing systems.

“There is no better place to work, and there are no better people to work with, than those in this agency,” said Wiseman. “NASA gave me tremendous responsibility, supported me through two space missions, and my time as chief astronaut, and was always there for my family when we needed it most. I’m thrilled to continue serving future missions and programs through the emeritus program.”

“Reid and Victor’s commitment to exploration, steady leadership, and service to our astronaut corps and our nation have made a lasting impact,” said Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. “Throughout their careers, they have each brought excellence, humility, and purpose to every role they have held at NASA. Their contributions have helped advance our mission and inspire those around them, leaving a legacy that will continue to shape the future of human spaceflight. We are immeasurably grateful for all they have given to NASA and are glad that this is not the end of their journey with the agency.”

“Reid and Victor are trusted teammates whose professionalism, calm leadership, and unwavering commitment to NASA have strengthened our office and inspired everyone around them,” said Scott Tingle, chief of the Astronaut Office at Johnson. “As they transition into their emeritus roles, they leave a legacy of operational excellence that will continue shaping the astronaut corps for years to come. We’re grateful that they will still be part of our community, sharing their experience and insight as they begin this next chapter.”

Among their many accomplishments at NASA, as Artemis II crew members, Glover and Wiseman were two of the four astronauts to first launch on top NASA’s SLS (Space Launch System) rocket aboard the Orion spacecraft for a mission around the Moon. Following a 10-day mission with crewmates NASA astronaut Christina Koch and CSA (Canadian Space Agency) astronaut Jeremy Hansen, they safely splashed down on April 10 as the first humans to travel to lunar orbit in more than 50 years, ultimately flying farther in space than anyone had before.

Support and knowledge transfer from both Glover and Wiseman is critical for the upcoming Artemis III mission as NASA prepares to return American astronauts to the lunar surface on the Artemis IV mission in 2028.

Curiosity Blog, Sols 4995-5001: 5,000 (Martian) Days on Mars

A black-and-white photograph from the Mars Curiosity rover showing a large, sweeping sand dune with a sharp, brightly sunlit crest. To the left are scattered flat rocks, and more rolling dunes stretch into the distant background.
NASA’s Mars rover Curiosity acquired this image along Chocolatal ripple using its Right Navigation Camera on Aug. 28, 2026 — Sol 4998, or Martian day 4,998 of the Mars Science Laboratory mission — at 13:58:36 UTC.

Written by William Farrand, Senior Research Scientist, Space Science Institute

Earth planning date: Friday, Aug. 28, 2026

The span of sols spanned by this blog post is noteworthy in several ways. First, Curiosity became a world-class (for Mars at least) mountaineer by passing the 1 kilometer mark of elevation from its landing site on the floor of Gale crater. This writer was on the Mars Exploration Rover science team and we were excited when the Spirit rover got to the top of Husband Hill in Gusev crater in August 2005. But that was a climb of 106 meters (about 348 feet) above its landing site, and Curiosity has passed 1000 meters (about 0.62 miles). 

Second, Saturday, Aug. 29, marked 5,000 Martian days (or sols) since Curiosity landed on Mars (that’s more than 5,137 Earth days, because a day on Mars lasts 24.6 hours). Congratulations are in order to the engineers and scientists who have made this landmark possible. 

Finally, in terms of its science activities Curiosity is examining a wind-formed, long, narrow, large ripple which has been named “Chocolatal.” Further examination will help determine if this feature could be classified as a “transverse aeolian ridge” or TAR. TARs have been observed across the Martian surface based on orbital imaging. The long axis of a TAR is oriented perpendicular to the local predominant wind direction. While this is not the first potential TAR that has been examined by Curiosity, its location, higher on the slopes of Mount Sharp invites questions about whether it will be composed of the same types of granular materials found in the lower TARs, or whether it has a different range of grain sizes and/or layering. 

Other questions to be addressed include how the ridge formed, whether it is active, how it has migrated, and, if it is immobile, then how has it stabilized?

At the start of the planning week, Curiosity was en route to the sand ripple and encountered interesting science targets along the way. In Monday’s two-sol plan, in-situ examinations were planned of the light-toned bedrock occurring along the rover’s path. Some of the rocks encountered near the rover had dark-toned thick coatings or remnant layers, and these were targeted for chemical examination by the rover’s ChemCam Laser Induced Breakdown Spectroscopy (LIBS) instrument. Mastcam and ChemCam Remote Micro Imager (RMI) mosaics were planned, for layers in buttes along the rover’s path, and on more distant sets of sand ripples.

A midweek planning session took advantage of the last drive, leaving the rover only a few meters from Chocolatal. ChemCam was able to target sand at the base of Chocolatal as well as nearby bedrock. Stand-off Mastcam high-resolution image mosaics of the ripple were also targeted. The drive planned midweek took the rover right into Chocolatal with one of its wheels and then backing off a little, so in the end-of-week plan, contact science could be planned within the trenched region.

The final planning session of the week, which extended through the landmark Sol 5000, involved MAHLI mosaics of the right wall of the trench to see if there is layering, and to assess any variations in grain size. It’s noteworthy that these MAHLI mosaics are being named in honor of our late colleague Paul Geissler, who was one of the foremost experts on the study of Martian TARs and who was working with the MAHLI team before his untimely passing earlier in the year. In-situ APXS measurements were planned of the coarse-grained surface of the ripple, and ChemCam LIBS measurements were planned on the top of Chocolatal, a sinuous feature looking like a “mohawk” haircut (see the accompanying image). LIBS was also planned on a dark band on its flank and at the back of the scuff/trench. Other activities in the three-sol plan included Mastcam mosaics, an AM Navcam dust-devil survey, Navcam suprahorizon survey, and APXS atmospheric measurements.

With 5000 sols of outstanding scientific accomplishments, the Curiosity science and engineering team looks forward to the next 5000 sols.

Anak Krakatau Rumbles Again

Anak Krakatau Rumbles Again

Eruptions are a regular occurrence at Anak Krakatau, a small volcano between the Indonesian islands of Java and Sumatra. Much of its activity remains relatively mild, but it occasionally puts on more impressive and hazardous shows of force. In early September 2026, a booming eruption lasting more than 24 hours sent gas and ash high into the atmosphere, disrupting thousands of flights and degrading air quality in parts of the country, including the capital city of Jakarta.

Satellites passing over the area during the eruption on September 5 captured images of the explosive activity. In the scene above, acquired with the OLI (Operational Land Imager) on the NASA-USGS Landsat 8 satellite, a white plume of volcanic gas billows over a brown ash cloud. Below, a wider view captured by the VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite shows the volcanic material dispersing over a large area.

Indonesia’s meteorological agency reported that ash had reached altitudes up to 6,000 meters (20,000 feet) to the east of the volcano and 15,000 meters (50,000 feet) to the west by September 6. The presence of ash in the atmosphere prompted the temporary closure of eight airports on Java and Sumatra, disrupting nearly 3,000 flights in and out of the area, according to news reports.

Ashfall affected populated areas, particularly to the east of Anak Krakatau in Jakarta and other parts of West Java, the Indonesian Humanitarian Coordination Platform (IHCP) reported. Volcanic ash poses health risks to people and can irritate the respiratory tract, eyes, and skin. However, this air quality hazard differs from the smoke produced by peatland fires elsewhere in the country in terms of particle characteristics, dispersal patterns, and protection measures, the IHCP noted. 

On September 6, the continuous explosive eruption from Anak Krakatau subsided, though the volcano kept rumbling. It returned to a more typical pattern of Strombolian eruptions, characterized by intermittent spurts of ash and volcanic material. Airports had resumed operation by September 8, but the volcano remained at the second-highest alert level on the country’s scale, as it has been since early July.

From the Corps to the Cosmos, featuring Jaden Caradine

From the Corps to the Cosmos, featuring Jaden Caradine

Jaden Caradine knew he wanted to be an engineer at eight years old. He just took a winding road to get there.

Before he enrolled at Embry-Riddle Aeronautical University, before he discovered the field that would become his focus, and before he landed a Pathways internship at NASA’s Langley Research Center in Hampton, Virginia, Caradine spent five years as a mechanic in the United States Marine Corps, four of them stationed in Japan. It was a deliberate detour, one that shaped how he approaches everything since.

“I’ve kind of always known I wanted to be an engineer,” he says. “I just had to figure out what kind.”

Finding the Overlap

Caradine grew up in the Salt Lake City area, raised by a mother who put him on a snowboard at four and on a rock face not long after. He was the kind of kid who learned to love science not for its own sake, but for what it could do. “Math is an enabling skill,” he says. “It’s not about doing the math. Math has a purpose and it’s useful.”

By the time someone asked young Jaden what he wanted to be, the answer was immediate. “I was building Legos,” he says, “and I just thought — I want to build stuff. I can’t really see myself being anything other than an engineer.”

Right out of high school, Caradine enlisted in the Marines, trained as a mechanic, and shipped out to Japan. During those five years, between the technical work and the distance from home, he started reading books on decision-making, career planning, and long-term thinking. He found a framework he keeps coming back to: ikigai, a Japanese concept that maps the intersection of what you’re good at, what you enjoy, what the world needs, and what you’re paid to do.

“Your ikigai is the thing where all of those overlap,” he says. Engineering was already in the picture. The question was what kind.

Chasing the Signal

The answer arrived through research and a company Caradine stumbled on while scanning the landscape of emerging aerospace technology. They were using magnets to spin a launch system to 14,000 or 15,000 RPM and release small satellites into orbit, recovering the energy on the way down through the same magnetic system. “I thought that was awesome,” he recalls. “So, I started looking into aerospace engineering, and it was a good fit.”

Once he had the field, the destination wasn’t hard to find. Caradine transferred to Embry-Riddle Aeronautical University’s Daytona Beach campus to study aerospace engineering and immediately started showing up everywhere he could — satellite conferences at Kennedy Space Center, industry events in Orlando, small satellite gatherings back in Salt Lake City. “I went to all the career fairs, even though I wasn’t looking for a job yet,” he says. “I just wanted to learn as much as I could, as fast as I could.”

At every NASA booth, he asked questions. He learned about Pathways, the program that places undergraduate and graduate students at NASA centers with the potential to convert to full-time civil service positions, but he waited a year to apply. “I hadn’t really done the things I wanted to do in order to write a strong application yet,” he says. He wrote the next application with the intention of using it as a practice run. He got in.

His reason for choosing NASA over industry was simple and firm. “NASA doesn’t work for profit,” he says. “We’re here to remove barriers so that industry can eventually do the things they weren’t able to do before.”


“Human beings are far more capable than we give ourselves credit for. A journey of a thousand miles starts with a single step and can only be taken one step at a time.”


Work Worth Doing

At NASA Langley, Caradine is part of the Systems Analysis and Concepts Directorate, where “we help agency leaders figure out why they should make certain decisions, especially those that have lots of moving parts,” he explains. Specifically, he works with the in-space servicing, assembly, and manufacturing (ISAM) team, a group focused on the emerging field of building and maintaining infrastructure in space, rather than simply launching and discarding it.

A major part of his summer was curating the State of Play, a comprehensive document that consolidates everything happening in the ISAM sector across government, academia, and industry into a single, navigable resource.

“Jaden joined the team and immediately contributed to this year’s State of Play update,” says Dale Arney, aerospace engineer and Caradine’s mentor. “He also created an automated tool that will help the team create future updates more quickly.”

That tool scrapes aerospace news from across the web, compiles relevant updates into organized tables, and produces a readable summary on a regular cadence. “It kind of replaced the need for everyone on the team to spend 30 or 40 minutes every day scrolling through news to keep up,” he says.

“Jaden was constantly looking for ways to improve himself, the team, and our products,” Arney adds. “He was eager to take the lead in trying a number of new processes and ideas to try to make them work for us.” 

No Silos

The thing that surprised Caradine most about NASA Langley had nothing to do with the technical work. He had expected some departmental siloing that could develop in large organizations, where people become experts in narrow areas with limited cross-pollination among teams.

“That’s not something I’ve experienced here,” he says. “We all talk to each other, across all teams. We share resources. We collaborate quite extensively.” He describes a culture that expects everyone to engage with the whole problem, not just their corner of it. “Everyone kind of bounces around on different teams to learn the whole aspect of the problem and support each other.”

For anyone considering the Pathways program, his advice is direct. “Do it,” he says. “Human beings are far more capable than we give ourselves credit for. If it seems like too much, break it down. A journey of a thousand miles starts with a single step and can only be taken one step at a time.”

Caradine heads back to Embry-Riddle as a junior this fall, with plans to return to Langley next summer. Grad school is on the horizon, and he’s exploring programs that nurture important analysis skills for SMAB, including decision, strategic, and systems analysis.

“Before coming here, I was trying to do everything and cast a wide net,” he says. “Now I know what I need to know how to do. That’ll give me the opportunity to focus my efforts on the high-value skill sets.”

Caradine’s instinct runs more toward fantasy than science fiction, but this one, he says, hits something real.

“I enjoy the leveling aspect — constantly improving, constantly getting better. In books it might be physical strength, but in reality, strength takes on many different forms. Constant improvement is quite rewarding in real life, as it is in books.”

The audiobook production, he adds, is its own experience: full sound design, character actors, the works. “It’s like listening to a movie.”

The team also recently convinced him to start Dune, by Frank Herbert. He’s about halfway through.
