The X-59 successfully completed its inaugural flight—a step toward developing quieter supersonic jets that could one day fly customers more than twice as fast as commercial airliners.

As NASA’s moon-landing plans with SpaceX hang in the balance, other bold ideas are quietly starting to take shape.

Scientist Avi Loeb has accused NASA of withholding critical information about 3I/ATLAS — the Manhattan-sized interstellar comet which he’s postulated could have extraterrestrial origins. The Harvard astrophysicist made these allegations during a recent appearance on “ The Joe Rogan Experience .”

Lockheed Martin's revolutionary X-59 supersonic jet completes first test flight, designed to break sound barrier with quiet 'thump' instead of sonic boom.

SpaceX posted a response to criticisms of delays in its Starship program from NASA acting Administrator Sean Duffy.

Blue Origin has test fired its New Glenn rocket engine as it makes final preparations for the launch of NASA’s ESCAPADE mission involving twin Mars orbiters. The static test fire of the heavy-lift rocket, captured by NASASpaceflight and shared below, lasted around 40 seconds and appeared to proceed without a hitch.

Many NASA contractors and federal civil servants are not being paid during the ongoing government shutdown, which could lead to delays.

NASA and Lockheed Martin debuted their first test run of a low-volume supersonic jet that’s expected to allow air passengers to travel faster than the speed of sound. The X-59 aircraft soared Tuesday from Lockheed Martin’s facility in Palmdale,

Elon Musk's SpaceX on Thursday said it proposed to NASA a simplified plan to send humans to the moon using its Starship rocket, as the agency presses its contractors to move more quickly toward beating China to the lunar surface this decade.
