Space Launch System Mission Scrubbed – Defense Security Monitor

The long-awaited Artemis I  mission – the first flight of NASA’s Space Launch System (SLS) rocket – was scrubbed on August 29 due to a hydrogen bleed line issue with one of the RS-25 engines. The next launch attempt will likely happen in early September.

SLS has been under development for over a decade.  The SLS is being designed to lift crew and cargo into orbit. In particular, it will carry the Multipurpose Crew Vehicle (MPCV), also called Orion. Initially, NASA expects the launch vehicle to carry 70 to 100 metric tons into orbit, with capacity eventually being raised to 130 metric tons. The SLS will be the center of NASA’s efforts to expand human exploration beyond low-Earth orbit.

In the Artemis I mission, the SLS rocket was planned to perform an uncrewed launch that would send an Orion spacecraft around the moon and return it to Earth. Artemis II will fly a crew around the moon, and Artemis III will perform the first crewed lunar landing since the Apollo missions.
