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.

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.

NASA is getting ready to launch its massive, fully expendable rocket for the first crewed flight to the Moon since Apollo. The agency’s new era of spaceflight comes with a few parts from its past, specifically three rocket engines that have previously flown on space shuttle missions.

The rocket is about to traverse four miles to the launchpad — at about 1 mph.

Four astronauts are scheduled to launch on a trip to fly around the Moon as early as Feb. 6 in the Orion spacecraft.
