CAPE CANAVERAL, Fla. (AP) — Grounded until at least April, NASA’s giant moon rocket is headed back to the hangar this week for more repairs before astronauts climb aboard. The space agency said Sunday it’s targeting Tuesday for the slow, four-mile (6.4-kilometer) trek across Kennedy Space Center, weather permitting.

NASA's second attempt to run a "wet test" of the Space Launch System (SLS) for its Artemis II mission was successful. Following a failure of some seals during the first attempt earlier this month, NASA pushed the launch back to March to conduct additional tests.

Astronauts Barry "Butch" Wilmore and Sunita Williams were expecting to spend eight to 10 days in space. They ended up​ remaining in orbit for 286 days.

NASA and Vast have signed an order for the sixth private astronaut mission to the International Space Station.

NASA released an independent investigation in Boeing's crewed flight test that launched in 2024. Hardware was not the most troubling failure.
