NASA's quiet supersonic X-59 aircraft has fired up its engines for the first time during a series of engine tests launched last week. Tests were also run for the first time without an external power source to verify that the X-59's systems can function on its own engine power.

X-59’s engine started for testing for the first time. NASA’s Quesst (“Quiet SuperSonic Technology”) mission recently achieved a key milestone as it began

NASA engineers fired the engines on the X-59 research aircraft in advance of planned test flights to determine if the aircraft can reduce sonic booms and make supersonic flight over land quieter.

NASA has fired up the engine of its experimental X-59 supersonic aircraft for the first time at Lockheed Martin's Skunk Works facility.

NASA has marked a major milestone in its creation of an experimental aircraft. Biden might want to crimp Iranian and Russian oil revenue once he doesn't have to worry so much about gasoline prices at home.

A try called Quesst Vid The aircraft NASA hopes will usher in a new generation of transport that's supersonic but also relatively quiet has fired up its engines for the first time as a test.… The X-59 Quiet Supersonic Technology (Quesst) airplane has been designed to generate what the agency refers to as a shaped sonic boom,

NASA and Lockheed Martin’s Skunk Works subsidiary have started the first testing phase of an engine that will power the X-59 experimental aircraft being built to achieve quiet supersonic flights under the space agency’s Quesst mission.
