Blue Origin postponed a planned second flight of its flagship New Glenn rocket on Sunday, delaying a mission seen as a crucial test for the Jeff Bezos-backed space company in its quest to challenge SpaceX.

Blue Origin is preparing a second launch of its New Glenn rocket, this time with twin Mars orbiters on board. The company will attempt to recover the rocket’s first stage.

This will be the second flight of the orbital rocket from Jeff Bezos’s space company and will include a key test of whether it can land a booster stage for later reuse.

New Glenn, the towering rocket built by Jeff Bezos's space company Blue Origin, is set to take off on its second mission Sunday as competition intensifies with Elon Musk's SpaceX.

Blue Origin has postponed the second flight of its New Glenn rocket, which was slated to send a pair of NASA spacecraft on the first step of their journey to Mars on Sunday afternoon. The heavy-lift launch vehicle was scheduled to take off from Cape Canaveral Space Force Station in Florida at 2:45PM ET.

It's an important launch for Jeff Bezos' space company, which is trying to prove its rockets can be re-used while delivering its first commercial payloads.

Blue Origin, the space company owned by billionaire Jeff Bezos, was forced Sunday to postpone the anticipated launch of its New Glenn rocket due to unfavorable weather conditions.

Blue Origin is scheduled to launch its New Glenn Rocket on Sunday afternoon at 2:45 P.M. from Cape Canaveral, marking only the second flight of this rocket. The New Glenn Rocket will launch NASA satellites for the Escapade Mission to Mars,
