NASA's X-59 Reaches Supersonic Speeds and Altitude in Key Test Flight
Hızlı Bakış
- NASA's X-59 research plane achieved Mach 1.4 and 55,000 feet in a recent test flight, demonstrating its capability for future supersonic flights over US communities.
- The plane is designed to produce a "quiet sonic thump" instead of a traditional sonic boom.

NASA's X-59 research plane is designed to fly at supersonic speeds without producing a loud sonic boom, aiming for a "quiet sonic thump." Recent test flights are demonstrating its capabilities for future missions over populated areas.
NASA's X-59 research plane took its first supersonic flight at the beginning of the month, and now it's demonstrated that it can reach the speed and altitude conditions it'll need to achieve for planned trips over US communities in the near future.
The X-59 is designed to fly at supersonic speeds without producing a loud sonic boom; instead, it'll make a "quiet sonic thump," according to NASA.
For now, though, it's flying alongside another research craft that does produce a sonic boom, to obscure whatever noise it makes as it undergoes testing.
In a test flight on Friday, the X-59 flew Mach 1.4, or about 924 mph, and reached an altitude of 55,000 feet.
For the previous flight, on June 5, it hit Mach 1.1.
The space agency says this latest test "was an even more critical step" than the one that preceded it, as it hit key targets that it'll replicate during its Quesst mission.
The Quesst mission, which is still months away, will see the X-59 fly over populated areas so NASA can get feedback from the public on what the sonic thump sounded like to listeners on the ground.
Before that, though, the plane will go through an acoustic validation phase, in which the team will measure its supersonic acoustic signature to make sure it is indeed breaking the sound barrier without producing a traditional sonic boom.

- What will public reaction be to the sonic thump?
- When will the Quesst mission officially begin?
