NASA's X-59 quiet supersonic jet recently passed electromagnetic interference testing, moving it one step closer to its first ...

NASA will measure the air vibrations caused by the jet’s sonic boom by surveying residents in areas where the X-59 passes overhead, but it will also need to measure it through scientific means.

When planes exceed Mach 1 (the speed of sound, or about 767 miles per hour—1,234 kilometers/hour for those using the metric ...

American space agency NASA announced it has completed the electromagnetic interference testing for the X-59 supersonic test ...

The X-59 jet is Nasa and Lockheed Martin's joint offering, which the pair hope will retire the deafening sonic boom that is usually associated with supersonic aircraft. The X-59 is designed to hit ...

NASA says the X59 supersonic jet will produce a sonic thump instead of a sonic boom, which might help lower it's noise.

"This reduces risk and ensures we're not learning about problems in the air." NASA's experimental X-59 aircraft continues to make progress toward its first flight with a new successful round of ...
