NASA's recently-retired SOFIA airborne observatory aircraft, the "flying telescope," also called Plant 42 home. The agency's ...

NASA announced a successful test of its X-59 aircraft at U.S. Air Force Plant 42 in Palmdale, Calif., that could lead to ...

More NASA's experimental X-59 aircraft continues to make progress toward its first flight with a new successful round of testing. The X-59 "quiet" supersonic jet was designed to break the sound ...

NASA's X-59 is taking slow steps towards supersonic flight, beginning taxiing tests at US Air Force Plant 42 in Palmdale, ...

"NASA will then fly the X-59 over several communities to gather data on human responses to the sound generated during supersonic flight," officials said in the statement from the space agency.

NASA and Lockheed Martin are finally ready to unveil the new X-59 Quesst on Jan. 12. The supersonic jet designed to break the sound barrier without creating a thunderous sonic boom.

NASA’s X-59 aircraft is parked near the runway at Lockheed Martin Skunk Works in Palmdale, California, on June 19, 2023. This is where the X-59 will be housed during ground and initial flight tests.

The X-59 is scheduled to take flight this year. Once fully operational and tested, NASA plans to fly the aircraft over select U.S. cities in 2026 and gather feedback from the public on the sound ...

NASA unveiled the X-59, an experimental supersonic aircraft designed to produce a quieter sonic boom. The explosive noise happens when an aircraft travels faster than the speed of sound.

The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to address one of the primary challenges to supersonic flight over land by making sonic booms quieter. Lockheed Martin Skunk Works ...
