Artemis I Launch Director Charlie Blackwell-Thompson has actually validated all goals have been met for the cryogenic presentation test, and teams are now proceeding with critical safing activities and preparations for draining the rockets tanks. After coming across a hydrogen leakage in a cavity in the tail service mast umbilical early in the filling process, engineers were able to fix the issue and proceed with the scheduled activities.

The 4 primary objectives for the cryogenic demonstration included examining the repair to resolve the hydrogen leakage determined on the previous launch attempt, packing propellants into the rockets tanks utilizing brand-new treatments, carrying out the kick-start bleed, and carrying out a pre-pressurization test.
The brand-new cryogenic loading procedures and ground automation were designed to shift temperature level and pressures gradually during tanking to reduce the probability of leaks that could be brought on by rapid modifications in temperature or pressure. After experiencing the leakage early in the operation, teams further decreased packing pressures to fix the concern and proceed with the presentation test. The pre-pressurization test enabled engineers to adjust the settings utilized for conditioning the engines throughout the terminal count and verify timelines before launch day to minimize schedule risk during the countdown on launch day.

Teams will examine the information from the test, together with the weather and other factors, before verifying preparedness to continue into the next launch opportunity. The SLS rocket stays in a safe setup as groups examine the next actions.
Artemis I is the very first in a series of increasingly complicated objectives. It will supply a structure for human deep space expedition and show our commitment and capability to extend human existence to the Moon and beyond. The main goal of Artemis I is to completely check the incorporated systems prior to crewed missions by operating the spacecraft in a deep area environment, screening Orions heat shield, and recovering the crew module after descent, splashdown, and reentry.
