00:00I was walking around quite happily after a few hours. To start with, I wanted to make sure I held
00:04on to something.
00:05People were holding me to say we've seen the Artemis 2 astronauts to stop them from possibly overbalancing.
00:11But we saw them coming out of the spacecraft looking cheerful, happy, waving, smiling and communicating pretty much as normal.
00:20And for a few days, again, it's amazing how we can adapt to these different situations.
00:25I think it's helpful if you can wear something to stop the blood flow going away from your head.
00:29Otherwise, you can feel lightheaded as well as feeling a bit wobbly because of balance.
00:35Some astronauts have what we call space adaptation syndrome.
00:39It's a posh phrase, really, for just meaning they feel sick.
00:42And it's a bit like any kind of motion sickness on Earth.
00:46If you're in a boat, sometimes in a car where our balance system affects the vagus nerve.
00:51And actually, you know, without taking any drugs, about half of all astronauts would actually vomit in space.
00:58The drugs are quite good now, the antiemetics.
01:01But the people who tend to feel space sick also tend to feel Earth sick when they get back.
01:06Again, the drugs are quite good.
01:07But looking at the astronauts coming back from space just recently from the moon, it looks like they were all
01:13feeling pretty good.
01:15So, yeah, and of course, the three that have gone before would have been chosen partly because they weren't space
01:21sick the first time.
