The Space Launch System rocket is intended to carry astronauts to the moon under the Artemis program. The wet dress rehearsal for the launch of the rocket will begin tonight, Saturday, June 18 and run through Monday, June 20.

NASA has attempted the test before. There were a number of small issues which the agency characterized as nuisances rather than major problems. Before the test could be attempted again, the issues had to be fixed. The rocket was taken off the launch pad at the Kennedy Space Center in Florida and returned to its temporary home in the Vehicle Assembly Building.

Since then NASA has been working on fixing the issues discovered during the first round of testing, with the rocket returning to the launch pad a few weeks ago ready for the test again.

NASA is on track to begin a two day wet dress rehearsal for the Artemis I mission. The test will start at 5pm. The launch team will arrive at their consoles inside the Launch Control Center at NASA's Kennedy Space Center in Florida.

This time, the test will be streamed. For the previous test, NASA provided a video feed of the launch pad but no commentary, which was controversial and has been done before with members of the press. There will be live commentary and a video feed of the rocket at the pad over the weekend. You can watch the live stream on NASA's channel.
