NASA replaces Artemis 1 moon rocket seal on launch pad

NASA’s Artemis 1 moon rocket remains on the launch pad, at least for now.

Artemis 1 will use the new Space Launch System (SLS) mega-rocket to send an unmanned Orion capsule into lunar orbit and back. NASA attempted to launch the epic mission on Saturday (September 3), but pulled out when it couldn’t troubleshoot a super cold liquid hydrogen leak (LH2) propellant in time for takeoff.
