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.

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.

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 astronauts Matthew Dominick, Mike Barratt, Jeanette Epps, and Tracy C. DysonNASA RELEASE: J24-015
Expedition 71 Astronauts to Discuss Mission in NASA Welcome Home Event
Four NASA astronauts will participate in a welcome home ceremony at Space Center Houston after recently returning from a mission aboard the International Space Station.
NASA astronauts Matthew Dominick, Mike Barratt, Jeanette Epps, and Tracy C. Dyson will share highlights from their mission beginning at 6 p.m. CST Wednesday, Dec. 4, during a free, public event at NASA Johnson Space Center’s official visitor center. The crew will also recognize key contributors to mission success in an awards ceremony following the presentation.
The astronauts will be available at 5 p.m. for media interviews before the event. Media may request an in-person interview no later than 5 p.m. Tuesday, Dec. 3, by emailing Dana Davis at dana.l.davis@nasa.gov.
Expedition 71
NASA’s SpaceX Crew-8 mission launched to the space station in March 2024 as the eighth commercial crew rotation mission. The crew spent 235 days in space, traveled 100 million miles, and completed 3,760 orbits around the Earth, splashing down off the coast of Pensacola, Florida, on Oct. 25, 2024. This was the first spaceflight for Dominick and Epps and the third spaceflight for Barratt, who has logged 447 days in space over the course of his career. The crew also saw the arrival and departure of eight visiting vehicles during their mission.
Dyson flew with an international crew, launching aboard the Soyuz MS-25 in March 2024. The six-month research mission was the third spaceflight of her career, and her second long-duration spaceflight. Dyson’s third spaceflight covered 2,944 orbits of the Earth and a journey of 78 million miles as an Expedition 70/71 flight engineer. She has now logged a total of 373 days in space, including more than 23 hours in four spacewalks. Dyson and her crewmembers landed safely in Kazakhstan on Sept. 24, 2024.
While aboard the station, the Expedition 71 crew contributed to hundreds of technology demonstrations and experiments including the bioprinting of human tissues. These higher quality tissues printed in microgravity could help advance the production of organs and tissues for transplant and improve 3D printing of foods and medicines on future long-duration space missions. The crew also looked at neurological organoids, created with stem cells from patients to study neuroinflammation, a common feature of neurodegenerative conditions such as Parkinson’s disease. The organoids provide a platform to study these diseases and their treatments and could help address how extended spaceflight affects the brain.
