NASA briefly halted a wet dress rehearsal for its Artemis II mission after engineers spotted a minor valve issue on the Space Launch System rocket.
Officials say the pause was precautionary and routine for complex launch operations, and crews were able to resolve the problem and complete the remaining test milestones. Artemis II is slated to be the first crewed flight of the Artemis program, sending astronauts around the Moon before returning to Earth, a key step toward future lunar landings. NASA says the program remains on track, stressing safety comes first as preparations continue.
