Blue Origin's New Glenn heavy-lift rocket is ready for its inaugural flight after successfully completing a wet dress rehearsal, simulating a full launch countdown. The test culminated in firing the rocket's seven engines for 24 seconds with its tanks filled and a payload mass simulator attached. With the Federal Aviation Administration granting a launch license, New Glenn is poised for its first uncrewed mission. Originally scheduled for October, carrying NASA satellites to Mars, the flight was delayed due to readiness issues. Now expected to launch in early 2025, New Glenn will carry Blue Origin's Blue Ring Pathfinder on its maiden voyage.
