NASA has begun a two-day practice countdown for its first moonshot with astronauts in 53 years. The dress rehearsal that started Saturday night will culminate with the fueling of the space agency's new moon rocket.

With the wet dress rehearsal, essentially a critical fueling test of the Artemis 2 Space Launch System moon rocket, now back on Feb. 2, NASA said in a statement that it can no longer target Feb. 6 or Feb. 7, the first two days of its launch window. The Artemis 2 launch window originally ran from Feb. 6 to Feb. 10.
