NASA 862, which is an F/A-18D now based at NASA’s Armstrong Flight Research Center in Edwards, California, arrives for the first time in 2021. The aircraft was stationed at the U.S. Naval Air Station Patuxent River in Maryland. Once here, the aircraft was sent for major maintenance, painting, and preparation to join the NASA Armstrong aircraft fleet.

The G-IV aircraft lifts off from NASA’s Armstrong Flight Research Center in Edwards, California, on March 18, 2025.

Tim Krall, NASA Armstrong support aircraft fleet manager, watches. Thomas completed her flight in the backseat of a NASA F-15 aircraft flown by NASA Armstrong chief pilot Wayne Ringelberg. For 38 years, Thomas has captured aerial photographs of research and science flights.

This is a front view of the vertical tail loads testing on a Navy F/A-18E that concluded in May, wrapping up the third phase of research at NASA’s Armstrong Flight Research Center in Edwards, California. The first two phases included loads calibration testing focused on the aircraft’s horizontal tails and wings. The aircraft is from the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland. NAVAIR retired its previous loads test aircraft and NASA Armstrong staff are assisting to prepare the new aircraft for its role to help safely manage flight maneuvers and determine how the F/A-18E fleet will perform if proposed upgrades are incorporated.

In a series of baseline flights beginning on June 24, 2024, the G-IV aircraft flew over the Antelope Valley to analyze aircraft performance. To accommodate a new radar instrument developed by JPL, NASA’s Airborne Science Program has selected the Gulfstream-IV aircraft to be modified and operated by Armstrong Flight Research Center in Edwards, California and will accommodate new instrumentation on board in support of the agency’s science mission directorate. Baseline flights began at NASA Armstrong in June 2024

Technicians from Johnson Space Center, dressed in flight suits, secure themselves inside a prototype of a crew transportation vehicle (CTV) for Artemis crewed missions outside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on May 11, 2022. Canoo Technologies Inc., was awarded a contract to design and provide the next generation of CTVs for the Artemis crewed missions. Representatives with Canoo were at the spaceport demonstrating the environmentally friendly fleet of vehicles. Artemis II will be the first Artemis mission flying crew aboard Orion. In later missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.
