Preparations for Next Moonwalk Simulations Underway (and Underwater)
The UAVSAR underbelly pod is in clear view as NASA’s Gulfstream-III research aircraft banks away over Edwards AFBNASA On a changing planet, where phenomena like severe hurricanes, landslides, and wildfires are becoming more severe, scientists need data to assess and model disaster impacts and to potentially make predictions about hazards. NASA’s C-20A aircraft is a significant asset that can carry key instruments for understanding the science behind these phenomena.
Based at NASA’s Armstrong Flight Research Center in Edwards, California, the C-20A is a military version of the Gulfstream III business jet and operates as an airborne science aircraft for a variety of Earth science research missions.
In October, the plane was deployed to fly over areas affected by Hurricane Milton. With winds of up to 120 miles per hour, the hurricane hit the Florida coast as a category 3 storm, and produced lightning, heavy rainfall, and a series of tornadoes. In the aftermath of the storm, the C-20A was outfitted with the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument to collect detailed data about the affected flood areas.
“Our team focused specifically on inland river flooding near dense populations, collecting data that could help inform disaster response and preparation in the future,” said Starr Ginn, C-20A aircraft project manager. “By all indications, this rapid response to support Hurricane Milton recovery efforts was a successful coordination of efforts by science and aircraft teams.”
The Uninhabited Aerial Vehicle Synthetic Aperture Radar, UAVSAR, is prepared for installation onto NASA’s C-20A aircraft. THE UAVSAR uses a technique called interferometry to detect and measure very subtle deformations in the Earth’s surface, and the pod is specially designed to be interoperable with unmanned aircraft in the future. It will gather data from Gabon, Africa in September of 2023.NASA/Steve Freeman The UAVSAR was developed by NASA’s Jet Propulsion Laboratory in Southern California, and uses a technique called interferometry to detect subtle changes to Earth’s surface. Interferometry uses the intersection of multiple wavelengths to make precise measurements. This detection system effectively measures the terrain changes or impacts before and after an extreme natural event.
When flown onboard an aircraft, radars like the UAVSAR can also provide more detail than satellite radars. “Where satellite instruments might only get a measurement every one to two weeks, the UAVSAR can fill in points between satellite passes to calibrate ground-based instruments,” Ginn said. “It takes data at faster rates and with more precision. We can design overlapping flights in three or more directions to detect more textures and motions on the Earth’s surface. This is a big advantage over the one-dimensional line-of-sight measurement provided by a single flight.”
The C-20A team also used the UAVSAR in October to investigate the Portuguese Bend landslide in Rancho Pales Verdes. The Portuguese Bend Landslide began in the mid- to late-Pleistocene period over 11,000 years ago. Though inactive for thousands of years, the landslide was reactivated in 1956 when a road construction project added weight to the top of it. Recently, the landslide has been moving at increasing rates during dry seasons.
NASA’s JPL scientists, Xiang Li, Alexander Handwerger, Gilles Peltzer, and Eric Fielding have been researching this landslide progression using satellite-based instruments. “The high-resolution capability of UAVSAR is ideal for landslides since they have relatively small features,” said Ginn. “This helps us understand the different characteristics of the landslide body.”
NASA flew an aircraft equipped with Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) flew above California fires on Sept. 3 and 10, 2020.NASA/JPL-Caltech The C-20A airborne observatory also provided crucial insight for studies of wildfire. The Fire and Smoke Model Evaluation Experiment (FASMEE), a multi-agency experiment led by the U.S. Department of Agriculture’s Forest Service Pacific Northwest Research Station, included flights of the C-20A. This experiment studied fire behavior and smoke.
“The airborne perspective allows FASMEE researchers to better understand fire behavior and smoke production,” said Michael Falkowski, program manager for NASA’s Applied Sciences Wildland Fire program. “Hopefully this data will help mitigate fire risk, restore degraded ecosystems, and protect human communities from catastrophic fire.”
Airborne data can inform how scientists and experts understand extreme phenomena on the ground. Researchers on the FASMEE experiment will use the data collected from the UAVSAR instrument to map the forest’s composition and moisture to track areas impacted by the fire, and to study how the fire progressed.
“We can explore how fire managers can use airborne data to help make decisions about fires,” added Jacquelyn Shuman, FireSense project scientist at NASA’s Ames Research Center in California’s Silicon Valley.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Jeff Renshaw is the lead attorney for procurement law in the Office of the General Counsel for NASA’s Stennis Space Center and the NASA Shared Services Center. NASA/Danny Nowlin NASA attorney Jeff Renshaw’s work has primarily revolved around two things: serving others and solving problems.
The New Orleans native retired as an U.S. Air Force judge advocate following more than two decades of service. Renshaw now has worked for more than eight years as an attorney advisor at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
As the nation’s largest multiuser propulsion test site, NASA Stennis supports and helps power both national and commercial space efforts and missions. Any activity at NASA Stennis is authorized by some form of written agreement. The Office of General Counsel, which Renshaw is a part of, works to ensure that work is conducted appropriately.
“I’m dedicated to being the best public civil servant I can be,” Renshaw said. “In this position, you are representing your client, which is NASA, the federal government, and the taxpayers, so it is important for me to stay updated with the latest legal developments to be the best advocate and advisor I can be.”
As lead attorney for procurement law, the Metairie, Louisiana, resident works alongside the Office of Procurement serving both NASA Stennis and the NASA Shared Services Center.
Some of Renshaw’s work includes reviewing Space Act contract agreements for commercial companies that use NASA Stennis facilities, along with activities for some of the more than 50 federal, state, academic, public, and private aerospace, technology, and research organizations that are part of the NASA Stennis federal city.
Renshaw is motivated to be an expert in his line of work – whether deployed as a U.S. Air Force procurement law attorney to Baghdad, the Horn of Africa, and Afghanistan, or working at NASA to help the nation return to the Moon. He spends a lot of time with NASA engineers to understand the in-and-outs of ongoing projects since any activity happening onsite involves the Office of General Counsel.
In addition to the U.S. Air Force, Renshaw has served in other legal profession roles, including as a law clerk for a Louisiana district court judge and a position in the Louisiana State Attorney General’s Office. He said working for NASA gives him the opportunity to focus on his area of expertise, while being involved in the agency’s great mission of exploration and discovery.
“I love NASA, and it is good to feel part of the team and to know that you are contributing to the mission,” he said.

At the edge of Las Cruces, New Mexico, surrounded by miles of sunbaked earth, NASA’s White Sands Test Facility (WSTF) is quietly shaping the future. There is no flash, no fanfare — the self-contained facility operates as it has since 1962, humbly and in relative obscurity.
Yet as New Mexico’s space industry skyrockets amid intensifying commercial spaceflight efforts across the state, WSTF feels a new urgency to connect with the community. With the facility’s latest Test and Evaluation Support Team (TEST3) contract now in its third year, Program Manager Michelle Meerscheidt is determined to make a mark.
“I think it’s very important we increase our public presence,” Meerscheidt said. “We are a significant contributor to NASA’s mission and our country’s aspirations for furthering space exploration.”
In September, TEST3 leadership joined forces with the City of Las Cruces to support the sixth annual Las Cruces Space Festival, a two-weekend celebration of the region’s rich relationship with the aerospace industry.
The Test and Evaluation Support Team (TEST3) team — Human Resources Manager Kristina Garcia (left), Program Manager Michelle Meerscheidt, and Deputy Program Manager/Business Manager Karen Lucht — prepares to meet with visitors at the Las Cruces Space Festival Astronomy & Industry Night on Sept. 13, 2024, in Las Cruces, New Mexico. NASA/Anthony Luis Quiterio Alongside WSTF, festival director Alice Carruth is working to open a world that many believe is off limits and others don’t know exists.
“Unless you’re driving over the mountains regularly and seeing the sign that says, ‘The Birthplace of the U.S. Space and Missile Program,’ you don’t tend to know what’s going on in your backyard,” Carruth said.
“The whole premise of the Space Festival is to make people understand what’s going on in their community, to encourage people to think about careers in the space industry, and to inspire the next generation.”
A featured speaker at the festival’s New Mexico State University Astronomy & Industry Night, Meerscheidt had the chance to do just that.
“It’s fun to see a lot of young kids that are wide-eyed and excited,” Meerscheidt said. “It’s nice to be able to encourage them to pursue their dreams.”
Among those wide-eyed festivalgoers was 6-year-old Camilla Medina-Bond, who was confident in her vision for the future.
“I want to be an astronaut when I grow up,” she said. “I want to visit the Moon.”
As for the details of her lunar mission, Medina-Bond’s plan is simple: “Just going to see what’s on it.” She has plenty of time to figure out the specifics — after all, giant leaps start with small steps. According to Meerscheidt, the aspiring astronaut has already taken the first and most critical step.
“That’s what NASA is all about,” Meerscheidt said. “Explore, be inquisitive. Open your mind, open your imagination, and go for it.”

Right: Medina-Bond immerses herself in another world as she operates a virtual reality headset. NASA/Anthony Luis Quiterio Medina-Bond’s aspiration is shared by many young dreamers. A 2024 global study by longtime NASA partner, the LEGO Group, found 77% of kids ages 4-14 want to travel to space.
Carruth acknowledged that keeping the attention of today’s always-scrolling, trend-driven generation is not easy, and that children’s fascination with space often wanes as they age.
“If you look at the statistics, space tends to be really cool until they get to middle school level, and then space isn’t cool anymore — not because it’s not cool, but because it then becomes inaccessible to a lot of students,” she said.
Still, Carruth is prepared to navigate the challenge.
“I want kids to understand that space is for everybody,” Carruth said. “I also want their parents and grandparents to understand why space is important and that this is a feasible career.”
Oscar Castrejon, who attended the festival with his 12-year-old son, Oscar Jr., is on his own mission to nurture that understanding. “I’ve learned early kids need to develop their own passions, but if they say ‘hey, I like this, I’m interested in it,’ then I’ll take them to it,” Castrejon said. “If their eyes get opened, if their imagination gets sparked, you never know — you could be looking at the next NASA scientist.”
Oscar Castrejon and his son Oscar Jr., age 12, stop by the White Sands TEST3 booth. Anthony Luis Quiterio WSTF TEST3 Deputy Program Manager and Business Manager Karen Lucht shares Castrejon’s philosophy, emphasizing the importance of authenticity.
“Speak[ing] to who you are as a person will ultimately lead to who you will become as a professional,” she said.
A remote test site, WSTF has its own ecosystem which Lucht compares to a “small city.” Among its residents are scientists and engineers, but also welders, writers, firefighters, and photographers — to name a few.
“White Sands offers endless opportunities for everybody,” Lucht said. “Every career has a path here.”
Lucht’s own journey illustrates the infinite potential that arises in diverse spaces like WSTF.
“I came from a town of less than a thousand people, and I never dreamt that I would work for NASA,” she said. “As someone who was told many times that I would never make it to my position, I look back on my career and realize there are no restraints. You really can do anything you want to do.”
For those wanting to join the ranks at WSTF, there is one important requirement: they must see themselves as stardust, a vital element in a grand cosmic plan.
“We’re looking for people who have the right perspective, the desire to learn and contribute to something bigger than themselves,” Lucht said.
At WSTF — a place where the stars feel close enough to touch — the sky is not the limit, it is only the beginning.

ESA’s Proba-3 will be the first mission to create an artificial total solar eclipse by flying a pair of satellites 150 metres apart. For six hours at a time, it will be able to see the Sun’s faint atmosphere, the corona, in the hard-to-observe region between the Sun’s edge and 1.4 million kilometres from its surface. This new technology combined with the satellite pair’s unique extended orbit around Earth will allow Proba-3 to do important science, revealing secrets of the Sun, space weather and Earth’s radiation belts.
