Unfortunately, by then they'll be denser than a neutron star which isn't great for buoyancy.

Because eventually we are going to have to leave this planet and if climate change keeps happening at the rate it is, that day will be sooner rather than later.

I'm starting to understand what that giant asteroid that looked like a cigar was.

You're right I was reading the burn speed. :-(

well, climate change (not man-made) is pretty much the fkn reason why we are even on this planet in the first place, so no biggie

The Earth's gravity outside of the atmosphere is not far off being equivalent to the surface until you get much further away so they've slowed down because the Earth's gravity is pulling them backwards.
They did the burn yesterday to gather enough speed to escape the Earth's gravity and then at somepoint they will cross a line where the Moon's gravity will come to dominate and pull them towards the Moon so they will speed up again.
That pull from the Moon will also slingshot them around the Moon and send them back towards Earth before Earth's gravity grabs them back. Earth's gravity is stronger so the return journey will be faster and take less time. They'll then maybe do another burn and use the thick atmosphere to slow down enough for re-entry.

Apparently re entry will be at 25000 mph fastest ever attempted, hope that heat shields top quality.The Earth's gravity outside of the atmosphere is not far off being equivalent to the surface until you get much further away so they've slowed down because the Earth's gravity is pulling them backwards.

I've had a few beers.
But...
And I'm expecting loads of people to have a go.
But I'm going to say it anyway.
If man went to the moon 50 odd years ago.
Why have they not been since.
Next to Buxton is a village called dove holes.
It was voted the ugliest village in Britain.
If Ithey landed in dove for the first time I can understand them saying fuck that were not going there again

I think the main reason is that it's massively expensive to do. Also, a lot of the technology to do it was lost and forgotten as the staff involved got old, senile and died. I suspect there was a sense of, "We've done that so we can tick it off now," so a loss of appetite for it.

Is that you, professor Brand?
Ask not why they’ve not gone back for 54years why they went in the first place!? To be first! Russia was first into space first with an animal in space a dog!
Now why they coming back again now because China said they are going to put a man on the moon by 2036 but the dark side where there is a possibility of ice, apparently there is massive craters on that side and because the sun don’t hit that part of the moon for long those massive craters have more chance of ice because less chance of melting!

So NASA has gone back to the moon because they want to build a new Fever Tree bar

Why do satellites stay in orbit then instead of crashing back down to earth?The Earth's gravity outside of the atmosphere is not far off being equivalent to the surface until you get much further away so they've slowed down because the Earth's gravity is pulling them backwards.
