So they need to check all systems are OK.

And then mission control will hopefully give them the go-ahead to go to the moon.

It takes about four days for them to get to the moon.

They'll be flying around the far side of the moon and hopefully seeing...

bits of the moon that haven't been seen with human eyes before.

The far side of the moon is the side we can't see from here on Earth.

And then they'll be making their way back home.

So they're not landing on the moon this time.

That's for Artemis 3, but they are flying around it.

And the rocket is going to be reaching incredible speeds eventually.

Today, we saw it moving really, really, really slowly.

So the rocket is nearly 100 metres tall.

It weighs about 5,000 tonnes.

It's carried on the back of this sort of monster machine called a crawler transporter.

So the entire journey takes up to 12 hours.

And the Apollo missions were all about a race with the Soviet Union.

This time around, it's with China, who've been pushing ahead to get to the moon.

They want to get astronauts there by 2030.

So it will be really interesting to see how the two continue and who gets there first, really.

I was stunned, actually.
