Launch teams at the Kennedy Space Center in Florida are set to load the Space Launch System rocket with more than 730,000 gallons of liquid hydrogen (LH2) and liquid oxygen (LOX) in a critical, prelaunch test called the wet dress rehearsal (WDR). Engineers are hoping they have fixed a hydrogen leak that stopped a previous dress rehearsal on Feb. 3.
The test is supposed to culminate on Thursday, Feb. 19, with a planned cutoff just prior to a simulated T-0 of 8:30 p.m. EST (0130 UTC).
Following a successful conclusion of the test, NASA will review the data and determine a launch date for Artemis 2.
NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, along with Canadian Space Agency (CSA) astronaut Jeremy Hansen will take the Orion spacecraft, "Integrity," out for a 10-day test flight around the Moon and back.
Live commentary with Spaceflight Now Reporter Will Robinson-Smith will begin at roughly 10:35 a.m. EST (1535 UTC). NASA is not providing live audio from Firing Room 1 during the test nor live audio updates from a public affairs officer during the duration of the test.
