The launch of NASA's mega moon rocket, the Space Launch System, marks the beginning of the Artemis I mission to the moon. A fly-by of the moon will be part of the test flight of the spaceship that will be carried into the rocket on August 29th.

At 10:33 a.m., the clock started to tick. 7:30 a.m.). The launch team is ready at NASA's Kennedy Space Center in Florida. Engineers will start to power up the rocket core stage and the spaceship from today onward.

There is a chance that the launch might have to be scrubbed because of a variety of reasons.

At a NASA press conference, the Artemis mission manager said that they were not going to promise that they would get off on Monday. We could have a range and public safety hold or a combination of those. We are happy with our setup on Monday. The tanking meeting that will happen late Saturday night will be the result of a poll done today by the mission management team.

The current outlook is good for Monday, however there is a chance of some offshore rain which could affect the launch. The weather officer at Space Launch Delta 45 said there was a 70% chance of good weather. The weather is looking good. There will be offshore showers and possibly a few storms.

There are backup launch opportunities on September 2 and September 5 if the weather gets bad.

We have a guide on how to watch the launch on Monday.

There is a recommended video.
