Nasa has launched its most powerful rocket yet from Cape Canaveral in Florida.
The 100m-tall Space Launch System took off at 06:47 today (01:47 UK time) in what was a big breakthrough for Nasa.
The Artemis I mission is part of Nasa’s plan to get a man and a woman on the moon by 2025.
There is no crew onboard the vehicle and it will be controlled on the ground by Nasa’s space experts.
The launch follows two previous attempts that were delayed due to technical issues.
What is the Artemis mission?
Nasa plans to send humans to the moon again, using their new Space Launch System.
The rocket, which is designed to make sending humans to the moon easier, needs to be tested before welcoming a crew onboard.
The Artemis I mission will send a special spacecraft called Orion around the moon and then back down to earth.
If this is a success, Nasa hopes it will prove they can send humans up to the moon.
Why was the mission delayed?
An attempt in August was delayed due to engine problems, and an attempt a month later was called off because of a liquid hydrogen leak.
It was delayed once more due to storm Ian in the USA.
