How to watch NASA’s Artemis 1 launch to the moon

NASA is preparing to try again Saturday to launch its Artemis 1 test flight on a long-awaited mission to send an unpiloted Orion crew capsule on a 42-day trip around the moon and back.

After a detailed review, and a forecast calling for a 60% chance of favorable weather, NASA’s Mission Management Team approved plans to begin fueling the Space Launch System rocket at around 6 a.m. EDT Saturday, setting the stage for blastoff at 2:17 p.m., the opening of a two-hour window.

Launch was initially scheduled for Monday morning, but NASA ran into problems during fueling, forcing the agency to scrub just as the launch window was opening. 

The SLS rocket — the most powerful booster NASA and its contractors have ever built — has 489 launch commit criteria that have to be met to permit a liftoff.

“We’ve got a whole host of things that could cause us to not get off on any given day,” mission manager Mike Sarafin told reporters at a Thursday evening news conference. “There’s no guarantee we’re going to get off (Saturday). But we’re going to show up, and we’re going to try, and we’re going to give it our best.”
