NASA has delayed a key prelaunch test for its Artemis II mission after bad weather affected conditions at Kennedy Space Center in Florida. The wet dress rehearsal, which simulates the full launch countdown and fueling process, has been moved to Monday, February 2. As a result, the earliest possible launch date has shifted to Sunday, February 8, with earlier dates now ruled out. The decision follows several days of unusually cold temperatures and strong winds across Florida, prompting engineers and managers to reassess risks to flight hardware and ground systems. NASA teams remain focused on weather trends and test performance before confirming a final launch date. The Artemis II crew continues to remain in quarantine in Houston.
Wet dress on February 2 and possible Artemis II launch shifts to February 8
Due to the bad weather, NASA has moved the Artemis II wet dress practice to Monday, February 2, at the Kennedy Space Center in Florida. With this change, the earliest launch date that could still work is Sunday, February 8. The launch dates of Friday, February 6, and Saturday, February 7, are no longer possible, but NASA won’t pick one until teams have looked at how the wet dress practice went. It would be changed every day if there were any more delays.Before the fake launch window opens during the wet dress practice on February 2 at 9 pm EST, the countdown begins, which is almost 49 hours away. NASA will keep an eye on the weather before the test.As it’s cold outside, experts have kept Orion running and changed its heaters to work better in colder weather. The weather is also taken into account when purges are used to keep spacecraft and rocket parts, like the booster aft skirts, in good shape.NASA to monitor weather closely during wet dress practiceThe crew of the Artemis II is still isolated in Houston. Managers are keeping an eye on when the crew will arrive.Engineers have been keeping a close eye on things as Florida has been hit by cold weather and strong winds over the past few days. Because the state’s arctic outbreak was so unique, managers compared the hardware’s abilities to what they thought would happen and decided to change the plan. Teams and the launchpad are still set up and ready for the wet dress practice. However, moving the test date will help NASA do better during the practice run, since the weather this weekend is likely to not meet launch standards. NASA will set up a separate channel just for recording wet dress behavior. The EPA will also keep a blog going with live information about the fueling test.
