NASA’s 737 aircraft was painted this week in Oklahoma as it progresses with modifications for use as a reduced gravity test aircraft for the agency. NASA’s Armstrong Flight Research Center in Edwards, California, took ownership of the aircraft from the United States Air Force in June. 

The aircraft will perform lunar-gravity parabolic flights to validate astronaut lunar suits and associated crew systems required to support Artemis mission objectives. These flights will happen at NASA’s Johnson Space Center in Houston for reduced-gravity operations, with NASA Armstrong oversight.

In addition, the aircraft will serve as a key asset for systems‑integration research for flight testing autonomy, sensors, and other digital systems.
