Preparations for Next Moonwalk Simulations Underway (and Underwater)
More than 100 scientists will participate in a field campaign involving a research vessel and two aircraft this month to verify the accuracy of data collected by NASA’s new PACE satellite: the Plankton, Aerosol, Cloud, ocean Ecosystem mission. The process of data validation includes researchers comparing PACE data with data collected by similar, Earth-based instruments to ensure the measurements match up. Since the mission’s Feb. 8, 2024 launch, scientists around the world have successfully completed several data validation campaigns; the September deployment — PACE-PAX — is its largest. From sea to sky to orbit, a range of vantage points allow NASA Earth scientists to collect different types of data to better understand our changing planet. Collecting them together, at the same place and the same time, is an important step used to verify the accuracy of satellite data.
NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite launched in February 2024 and is collecting observations of the ocean and measuring atmospheric particle and cloud properties. This data will help inform scientists and decision makers about the health of Earth’s ocean, land surfaces, and atmosphere and the interactions between them.

Credit: NASA/Kim Shiflett To make sure the data from PACE’s instruments accurately represent the ocean and the atmosphere, scientists compare (or “validate”) the data collected from orbit with measurements they collect at or near Earth’s surface. The mission’s biggest validation campaign, called PACE Postlaunch Airborne eXperiment (PACE-PAX), began on Sept. 3, 2024, and will last the entire month.
“If we want to have confidence in the observations from PACE, we need to validate those observations,” said Kirk Knobelspiesse, mission scientist for PACE-PAX and an atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This field campaign is focused on doing just that.”
Scientists will make measurements both from aircraft and ships. Based out of three locations across California — Marina, Santa Barbara, and NASA’s Armstrong Flight Research Center in Edwards — the campaign includes more than 100 people working in the field and several dozen instruments.
“This campaign allows us to validate data for both the atmosphere and the ocean, all in one campaign,” said Brian Cairns, deputy mission scientist for PACE-PAX and an atmospheric scientist at NASA’s Goddard Institute for Space Studies in New York City.
On the ocean, ships, including the National Oceanic and Atmospheric Administration (NOAA) research vessel Shearwater, will gather data on ocean biology and the optical properties of the water. Scientists onboard will gather water samples to help define the types of phytoplankton at different locations and their relative abundance, something that PACE’s hyperspectral Ocean Color Instrument measures from orbit.

Credit: Judy Alfter/NASA Overhead, a Twin Otter research aircraft operated by the Naval Postgraduate School in Monterey, California, will collect data on the atmosphere. At altitudes of up to 10,000 feet, the aircraft will sample and measure cloud droplet sizes, aerosol sizes, and the amount of light that those particles scatter and absorb. These are the atmospheric properties that PACE observes with its two polarimeters, SPEXOne and HARP2.
At a higher altitude — approximately 70,000 feet up — NASA’s ER-2 aircraft will provide a complementary view from above clouds, looking down on the atmosphere and ocean in finer detail than the satellite, but with a narrower view.

In addition, two instruments called the Portable Remote Imaging SpectroMeter and Pushbroom Imager for Cloud and Aerosol Research and Development — from NASA’s Jet Propulsion Laboratory in Pasedena, California, and NASA’s Ames Research Center in California’s Silicon Valley, respectively — will measure essentially all the wavelengths of visible light (color). The remote sensing measurements are key for scientists who want to test the methods they use to analyze PACE satellite data.
Together, the instruments on the ER-2 approximate the data that PACE gathers and complement the in situ measurements from the ocean research vessel and the Twin Otter.
As the field campaign team gathers data, PACE will be observing the same areas of the ocean surface and atmosphere. Once the campaign is over, scientists will look at the data PACE returned and compare them to the measurements they took from the other three vantage points.
“Once you launch the satellite, there’s no more tinkering you can do,” said Ivona Cetinic, deputy mission scientist for PACE-PAX and an ocean scientist at NASA Goddard.
Though the scientists cannot alter the satellite anymore, the algorithms designed to interpret PACE data can be adjusted to make the measurements more accurate. Validation checks from campaigns like PACE-PAX help scientists ensure that PACE will be able to return accurate data about our oceans and atmosphere — critical to better understand our changing planet and its interconnected systems — for years to come.
“The ocean and atmosphere are such changing environments that it’s really important to validate what we see,” Cetinic said. “Understanding the accuracy of the view from the satellite is important, so we can use the data to answer important questions about climate change.”

Perseverance Kicks off the Crater Rim Campaign!
Mastcam-Z mosaic made of 59 individual Mastcam-Z images showing the area Perseverance will climb in the coming weeks on its way to Dox Castle, the rover’s first stop on the crater rim. NASA/JPL-Caltech/ASU/MSSS Perseverance is officially headed into a new phase of scientific investigation on the Jezero Crater rim!
For the last 2 months, the Perseverance rover has been exploring the Neretva Vallis region of Jezero Crater, where rocks with interesting popcorn-like textures and “leopard spot” patterns have fascinated us all. Now, the rover has begun its long ascent up the crater rim, and is officially kicking off a new phase of exploration for the mission.
Strategic (longer-term) planning is particularly important for the Mars 2020 mission given the crucial role Perseverance plays in collecting samples for Mars Sample Return, and the Mars 2020 team undertakes this planning in the form of campaigns. Perseverance has now completed four such campaigns— the Crater Floor, Delta Front, Upper Fan and Margin Unit campaigns respectively— making the Crater Rim Campaign next in line. Given its broad scope and the wide diversity of rocks we expect to encounter and sample along the way, it may be the most ambitious campaign the team has attempted so far.
The team also has less information from orbiter data to go on compared to previous campaigns, because this area of the crater rim does not have the high-resolution, hyperspectral imaging of CRISM that helped inform much of our geological unit distinctions inside the crater. This means that Mastcam-Z multispectral and SuperCam long-distance imaging will be particularly useful for understanding broadscale mineralogical distinctions between rocks as we traverse the crater rim. Such imaging has already proved extremely useful in the Neretva Vallis area, where at Alsap Butte we observed rocks that appeared similar to each other in initial imaging, but actually display an Andy-Warhol-esque array of color in multispectral products, indicative of varied mineral signatures.
Our next stop is Dox Castle where Perseverance will investigate the contact between the Margin Unit and the Crater rim, as well as rubbly material that may be our first encounter with deposits generated during the impact that created Jezero crater itself. Later in the campaign, we will investigate other light-toned outcrops that may or may not be similar to those encountered at Bright Angel, as well as rocks thought to be part of the regionally extensive olivine-carbonate-bearing unit, and whose relationship to both Séítah and the Margin Unit remains an interesting story to unravel. Throughout this next phase of exploration, comparing and contrasting the rocks we see on the rim to both each other and those previously explored in the mission will be an important part of our scientific investigations.
The whole Mars 2020 science team is incredibly excited to be embarking on the next phase of Perseverance’s adventure, and we expect these results, and the samples we collect along the way, to inform our understanding of not just Jezero itself, but the planet Mars as a whole. We can’t wait to share what we find!

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Early research at NASA’s Ames Research Center in California’s Silicon Valley — then known as NACA Ames Aeronautical Laboratory – included ground tests of “hot wing” anti-icing systems on a Lockheed 12A aircraft. NASA works every day to improve air travel – and has been doing so since its creation decades ago. On National Aviation Day, NASA and all fans of aviation get the chance to celebrate the innovative research and development the agency has produced to improve capability and safety in flight.
NASA’s Ames Research Center in California’s Silicon Valley has a historic legacy in aeronautics research. When the center was founded in 1939 by the National Advisory Committee for Aeronautics (NACA), its early research included working to reduce icing on aircraft wings.
When ice coats the wings of an airplane, it reduces lift and increases drag, which can cause the aircraft to lose altitude and control. Ames researchers developed different approaches to solve the icing challenge, including a “hot wing” thermal anti-icing system. The system worked by running hot engine exhaust along the leading edges of aircraft wings, warming them and preventing ice buildup. Ames researchers modified aircraft and tested them before traveling to Minnesota, where they were flown in icy conditions.
Today, many turbine-powered aircraft, like passenger jets, use “bleed air” anti-icing systems, which warm the leading edges of aircraft wings using compressed air from their engines. These systems are built upon the early research and testing done at Ames.
The legacy of aviation innovation continues at Ames, through aeroscience research like wind tunnel testing, air traffic management, and advanced aircraft systems.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Meet four employees from NASA’s Glenn Research Center who have a personal connection to aviation, at work and beyond.Credit: (Left to right): Waldo Acosta, Jared Berg, Lori Manthey, Lindsay Kaldon The first “A” in NASA stands for aeronautics. Glenn Research Center in Cleveland is just one of several NASA centers conducting revolutionary research to make flight cleaner, safer, and quieter.
But an interest in flying goes beyond the professional for many at NASA. Meet a handful of NASA Glenn employees who have a personal connection to aviation, at work and beyond.
Jared Berg
“I think my flying and engineering work positively influence each other. Flying integrates a lot of technical disciplines and serves as a real-word application of things I know theoretically about aerodynamics or heat transfer.”

Right photo: A view out the plane window.Credit: Jared Berg Planting the Seed: Berg grew up reading aviation books with his family and building model planes. Attending the EAA AirVenture airshow in Oshkosh, Wisconsin, throughout childhood inspired him to pursue flight training once he had a full-time NASA job.
Joining the Club: Berg is currently a member of the NASAIRS Flying Club at NASA Glenn, which he says helps make flying more accessible and lets him constantly learn from other pilots.
Flying High: Berg has now been flying recreationally for over a decade and considers it a part of his everyday life. “Flying allows an escape from the mundane and brings a sense of adventure to traveling,” Berg said. “You also get to experience nature, specifically weather but also the land you’re flying over, in a way that’s relatively raw and somehow personal.”
Lindsay Kaldon
"I love the feeling after takeoff and when you’ve reached cruising altitude. It’s as if all the stresses of life wash away when you’re up there in the sky. Being up in the clouds with all the beauty of the Earth below, it’s as if you’re in heaven.”
Lindsay Kaldon
Fission Surface Power Project Manager

Right photo: Kaldon celebrates passing her private pilot exam.Credit: Lindsay Kaldon Air Force and Astronauts: Kaldon’s father was an Air Force F-16 crew chief and a member of the Thunderbirds demonstration team, so Kaldon was no stranger to jets growing up. “Every day was an airshow living on the base that they trained out of,” Kaldon said. After earning a bachelor’s degree in electrical engineering, Kaldon joined the Air Force herself with hopes of one day becoming an astronaut.
Going Solo: Kaldon later earned her private pilot’s license and says she’ll always remember her first solo cross-country flight. She chose Kitty Hawk, the site of the Wright brothers’ first flight, as her destination.
Keeping the Energy: A monument that stands along the runway at Kitty Hawk is inscribed with words Kaldon remembers whenever solving difficult challenges through her work at NASA. “It says, ‘Achieved by Dauntless Resolution and Unconquerable Faith.’ The Wright brothers were faced with a lot of doubters who didn’t think flight was possible. Yet they proved them wrong and never gave up,” Kaldon said. “I love that. When things get tough, I just close my eyes and think about that phrase.”
Lori Manthey
“I encourage anyone who has an interest in flying to take a discovery flight at your local airport. If you get bitten by the flying bug, it just may become a life-long obsession. Ask me how I know!”
Lori Manthey
Chief of Administrative Services and Exchange Operations Manager

Right photo: Lori Manthey at the Grumman Cheetah controls.Credit: Lori Manthey Head in the Clouds: After a discovery flight in a small Cessna 150 plane, Manthey was hooked on flying. On weekends and evenings after beginning a full-time NASA job, she hopped in a Piper Tomahawk single-engine trainer at Lorain County Regional Airport to earn her private pilot certificate. “I love the feeling of floating in the air and seeing the world below,” she said.
Women in Aero: Manthey is passionate about advancing and supporting female pilots and currently serves as membership chair of the Lake Erie chapter of the Ninety-Nines, an organization started by Amelia Earhart in 1929. She is also a member of the Cleveland chapter of Women in Aviation.
Looking to the Future: Every year, Manthey participates in Girls in Aviation Day at Cleveland’s Burke Lakefront Airport to introduce girls to the world of aviation. “I think it is so important to help encourage young women and girls to become part of the next generation of female pilots,” she said.
Back in the Cockpit: Manthey is currently working to earn her instrument rating, which will let her fly “blind” in cloudy and foggy weather conditions.
Waldo J. Acosta
“Flying gives me a thrill. The perspective you’re able to see of the world from up in the sky is a special feeling. Aircraft have the ability to take us all over the world so we can experience different cultures and meet different people, and that has shaped me into who I am today.”
Waldo J. Acosta

Acosta, NASA/Jef Janis Family Ties: Throughout Acosta’s childhood, Acosta’s father, a former researcher at NASA Glenn, brought his family along on work trips to the EAA AirVenture airshow in Oshkosh, Wisconsin. “I fell in love with everything related to flying during those trips, and they set the tone early on my path to working in aviation,” Acosta said.
Next Steps: Acosta started taking flying lessons while studying aerospace engineering at The Ohio State University, eventually receiving his private pilot’s license.
Safety First: Overseeing testing and maintenance operations at NASA Glenn’s Icing Research Tunnel, Acosta is now directly involved in aviation safety research. The facility, the longest-running icing wind tunnel in the world, helps NASA and industry study how ice affects aircraft and test ice protection systems and tools.
Flying Full Circle: Acosta still attends airshows every chance he can get and has taken both his father and wife soaring into the clouds.
