The airborne Lunar Spectral Irradiance (air-LUSI) instrument is moved across the hangar floor by robotic engineer Alexander McCafferty-Leroux ,from right to left, co-investigator Dr. John Woodward, NIST astronomer Dr. Susana Deustua, air-LUSI chief system engineer Dr. Kathleen “Kat” Scanlon, and members of the ER-2 ground crew at NASA’s Armstrong Flight Research Center in Edwards, California, in March 2025.NASA/Genaro Vavuris Flying high above the clouds and moon-gazing may sound like a scene from a timeless romance, but NASA did just that in the name of Earth science research. In March 2025 pilots took the agency’s ER-2 science aircraft on a series of night flights over NASA’s Armstrong Flight Research Center in Edwards, California, as the Moon increased in visible size. For those few nights, the high-flying plane was converted into a one-of-a-kind airborne lunar observatory.
The Airborne Lunar Spectral Irradiance, or air-LUSI, mission observed the Moon at different phases and measured the sunlight reflected by the lunar surface. Specifically, the instrument tracks the amount of light reflected at different wavelengths. This information enables scientists to use the Moon as a calibration tool for Earth-observing sensors.
As an “absolute reference, the Moon also becomes the perfect benchmark for satellites to consistently and accurately measure processes on Earth,” said Kevin Turpie, air-LUSI’s principal investigator and a researcher based at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. This helps scientists to improve the precision of many different measurements, including data on weather patterns, vegetation growth, and ocean conditions.
As the highest-flying platform for airborne science, the ER-2 can fly the air-LUSI instrument in the stratosphere, above 95% of the atmosphere. Data collected at an altitude nearing 70,000 feet are highly accurate because the air is predominantly clear of the gases and particles found in the lower atmosphere that can interfere with measurements.
The ER-2 aircraft is parked in a hangar at NASA’s Armstrong Flight Research Center in Edwards, California, in March 2025. The plane is prepared for takeoff to support the airborne Lunar Spectral Irradiance, or air-LUSI, mission.NASA/Genaro Vavuris “To date, air-LUSI measurements of the Moon are the most accurate ever made,” said Kelsey Bisson, the NASA program scientist supporting the mission. “Air-LUSI data can advance our ability to understand the Earth and our weather, and they provide a new way to calibrate satellites that can result in cost savings.”
The quality of these data has transformative implications for satellite and Earth observing systems. The improved accuracy and enhanced ability provided by air-LUSI data flown on the ER-2 reduces the need for onboard reference devices, effectually cutting satellite costs.
The air-LUSI project is a collaboration between scientists and engineers from NASA, the National Institute of Standards and Technology, the U.S. Geological Survey, the University of Maryland Baltimore County, and McMaster University in Ontario.

The McMaster team developed the Autonomous Robotic Telescope Mount Instrument System and High-Altitude Aircraft Mounted Robotic (HAAMR) telescope mount, which support the air-LUSI system.
Dr. John Woodward, of the National Institute of Standards and Technology and co-investigator on the airborne Lunar Spectral Irradiance (air-LUSI) mission, prepares the instrument for upload onto the ER-2 aircraft in March 2025 at NASA’s Armstrong Flight Research Center in Edwards, California.NASA/Genaro Vavuris The HAAMR telescope mount was integrated onto the ER-2 and flown for the first time during the science flights in March. This new lunar tracking system is contributing to what John Woodward IV, co-investigator for air-LUSI, called the “highest accuracy measurements” of moonlight. To improve Earth observation technology, air-LUSI represents an important evolutionary step.

NASA astronaut and SpaceX Crew-10 Pilot Nichole Ayers.Credit: SpaceX Students from Dade City, Florida, will have the chance to connect with NASA astronaut Nichole Ayers as she answers prerecorded science, technology, engineering, and mathematics-related questions from aboard the International Space Station.
Watch the 20-minute space-to-Earth call at 1 p.m. EDT on Friday, April 11, on NASA+ and learn how to watch NASA content on various platforms, including social media.
The event, hosted by Academy at the Farm and open to students and their families, will occur in Dade City. Academy at the Farm is a charter school that plans to use the event to connect the students with space exploration and the work being done aboard the space station.
Media interested in covering the event must RSVP by 5 p.m., Wednesday, April 9, to Ashley Cantwell at acantwell@academyatthefarm.com or 813-957-8878.
For more than 24 years, astronauts have continuously lived and worked aboard the space station, testing technologies, performing science, and developing skills needed to explore farther from Earth. Astronauts aboard the orbiting laboratory communicate with NASA’s Mission Control Center in Houston 24 hours a day through SCaN’s (Space Communications and Navigation) Near Space Network.
Important research and technology investigations taking place aboard the space station benefit people on Earth and lays the groundwork for other agency missions. As part of NASA’s Artemis campaign, the agency will send astronauts to the Moon to prepare for future human exploration of Mars; inspiring Artemis Generation explorers and ensuring the United States continues to lead in space exploration and discovery.

As an Air Force veteran from Spartanburg, South Carolina, Alex Olley now serves as a contract specialist in the International Space Station Procurement Office at NASA’s Johnson Space Center in Houston.
Olley joined NASA as a Pathways intern in January 2023 to turn his lifelong goal into a reality—bringing his unique experience in the defense and space industries to support one of humanity’s most ambitious endeavors.

His role requires sharp attention to federal regulations and a deep understanding of business practices, all while supporting the astronauts who live and work 250 miles above Earth.
“I take great pride in the opportunity that I get to contribute to NASA’s mission each day,” he said. “I’m incredibly grateful for my time here, and it feels like a significant achievement, especially because many of my friends and family have shared how inspired they are to pursue their own goals as a result.”

Image courtesy of Alex Olley A quote shared by Johnson’s director of the Office of Procurement, Bradley Niese, became a guiding principle that has shaped Olley’s NASA experience: “People are the mission, and if we take care of the people, the mission will take care of itself.”
That mindset has taught him the value of building relationships within the office, which, he says, often leads to smoother operations and greater motivation.
“It’s much easier to be passionate about the mission when you know everyone around you shares the same dedication,” he said. “With such a strong support system, I’ve learned that I can achieve anything, no matter how challenging or confusing the task may seem at first.”
Early on, however, he struggled with imposter syndrome. “I felt like I didn’t belong or wasn’t good enough to contribute meaningfully toward our goals,” said Olley. “I overcame that feeling by taking a chance and sharing my thoughts on a work process.”
To his surprise, his team embraced the idea—and implemented it. That moment became a turning point, eventually leading to Olley becoming one of the office leaders for a wellness initiative called Better toGether—a creative nod to their office code, “BG.” The program was designed to promote physical and mental well-being in the workplace through activities like NASA Moves, an agencywide challenge that encourages employees to track their steps and commit to at least 20 minutes of physical activity each day. Twice a week, Olley leads brief team meetings focused on desk-friendly wellness tips such as stretches to prevent carpal tunnel and improve posture.

“I want to pass on my perspective on Johnson’s mission: Dare, Unite, and Explore,” he said. “DARE to take on the challenge and face it head on, UNITE with your peers, and never be afraid to EXPLORE the unknown.”
