NASA Artemis II Launch LIVE: NASA begins fuelling the rocket
The launch team transitioned to the fast fill of liquid hydrogen (LH2) for the interim cryogenic propulsion stage, or SLS (Space Launch System) rocket upper stage
After completing the chilldown phase, this step rapidly loads super-cold LH2 into the SLS upper stage tanks, ensuring the upper stage is fueled and ready to perform its fundamental role of raising the Orion spacecraft into a high Earth orbit ahead of a proximity operations demonstration test and Orion’s translunar injection burn.
Fast fill accelerates the fueling process while maintaining safety, marking another major milestone in the countdown as Artemis II moves closer to liftoff.— nasa.gov.in
