The second Artemis II wet dress rehearsal is tonight, with a simulated launch window set for 8:30pm.
How it works: The test will run launch and support teams through the full range of launch operations, including loading and draining the liquid hydrogen fuel.
Catch up quick: The mission's first wet dress rehearsal, earlier this month, experienced a fuel leak reminiscent of similar problems seen during the Artemis I mission.
The launch window for Artemis II, which will send four astronauts around the moon and back for the first time in more than 50 years in preparation for Artemis III's moon landing, opens March 6.
