The most recent Artemis 1 "wet dress rehearsal" wasn't perfect, but it was good enough to keep the NASA moon mission on course for liftoff a few months from now.

Artemis 1's Space Launch System (SLS) rocket and Orion capsule wrapped up the wet dress — a roughly 50-hour series of fueling tests and countdown simulations — on Monday (June 20).

The agency will roll SLS and Orion back to the Vehicle Assembly Building (VAB) at Kennedy next week to prepare the rocket and spacecraft for launch and repair a leak detected during the most recent rehearsal," agency officials wrote in an update today (opens in new tab) (June 23).

("Kennedy" is NASA's Kennedy Space Center in Florida, or KSC for short.).

"NASA plans to return SLS and Orion to the pad for launch in late August," they added.

— For Artemis moon missions, science will reign supreme.

Artemis 1 will be the first mission for the SLS and for NASA's Artemis program, which aims to establish a sustainable, long-term human presence on the moon by the end of the 2020s.

Artemis 1 will send an uncrewed Orion on a roughly month-long trip around the moon, potentially paving the way for a first crewed Artemis flight in 2024 and a crewed lunar landing a year or two later!
