Send in your questions about Artemis II

The countdown is well and truly on for the first manned moon mission in 50 years.

While the astronauts prepare to burn through the atmosphere and into space, we want to know what burning questions you have about the Artemis II mission.

Newsround will be chatting to BBC science correspondent Georgina Rannard about the launch.

What do you want to know? Pop your questions in the comments below.

Nasa say there is an 80% chance of good weather conditions to allow the launch to take place on Wednesday night.

The astronauts say they are ready to go but if the weather isn't ideal or the rocket isn't ready to go, the mission will be postponed again and they're ready for that too.

Maybe you want to know why they're just going around the Moon and not landing on it yet or maybe you want to know how the astronauts sleep in space without floating away.

There's no question too big or small, let us know what you want answered in the comments below.
