BBC: The first space walk

Hello, Neil! I watched that space movie last night - the one where those astronauts are stranded in space. 

Stranded means stuck in a place with only a small chance of leaving, Gravity, you mean?

That's the one. And this year marks the 50th anniversary of the first ever space walk. On 18th March 1965 Russian cosmonaut Alexei Leonov was the first man to drift free in space- 500km from the surface of Earth. And that's the subject of today's show!

What on earth must that have felt like?

Ah ha! Exactly. It would have felt like nothing on earth- and that's to say, very strange indeed. He was the first person to experience the colourful geography of our planet stretched out before him. 

Very poetic, Rob! But moving on, how about answering today's quiz question: How long did the first space walk last? Was it...

a) 2 minutes b) 12 minutes  or c) 22 minutes ?

All quiet short- so I think I'll go for the one in the middle- 12 minutes. 

We'll find out if you're right or wrong later on. Now, 'cosmonaut' literally means 'sailer of the universe'. But Leonov's mission wasn't plain sailing- in other words, it wasn't easy or straightforward. 

That's right. No one had ever gone out into space before- it was unknown territory- unknown territory means a place or activity that people do not know anything about or having not experienced before. And as it happens, there were big problems. 

When Leonov left the capsule his spacesuit inflated- or swelled - like a ballon because the pressure inside the suit was greater than outside. This made it impossible for Leonov to get back through the door of the spacecraft, putting him in a life-threatening situation. 

Let's listen to Helen Sharman, the first Briton in space, talking about it. 

So he decrases the pressure of his suit, which means that it's a bit more able to move inside it, but it means the amount of oxygen he's got around his face is now dangerously low so he can't cope with that for very long. So if he's not able to get tin quickly, he's going to die of oxygen starvation, um [...]  so he had the presence of mind to get on with all of this, got back in, swivelled himself round, managed to close the airlock, and then when the pressure was equilibrated was finally able to, you know, hug his compatriot up there in space. 

Now, if you can't cope with something it means you are unable to deal successfully with a difficult situation. And here the situation was having very little oxygen. 

But Leonov had the presence of mind to find a solution. Presence of mind means being able to react quickly and stay calm in a difficult or dangerous situation. 

And if I was in Leonov's shoes- meaning if I was in his situation- I would have panicked big time!

And there was plenty more to panic about before the mission was over. The spacecraft's automatic re-entry systemA failed so the cosmonauts had to fire the rockets manually- meaning controlled by hand- which they had never done before. 

And that's not all. Their capsule failed to detach- or seperate- from the spacecraft's equipement module, and this sent them tumbling through space towards Earth. 

But the capsule did finally detach. And then you would think they'd have been home and dry, wouldn't you? Home and dry means being close to achieving a goal. 

Well, they certainly weren't dry. The capsule touched down- or landed- hundreds of killometer off course in freezing Siberial populated only by wolved and bears. Leonov had sweated so much on the space walk that his boots were filled with water up to his knees! Both cosmonauts had to wring out- or twist and squeeze- their clothes to avoid frostbite.

 And off course, by the way, means not following the right route. Those men must have been overjoyed when they were finally airlifted to safety  two days later!

But what seems unfair to me is, we all know about the Apollo moon landing, but how many of us know about the first space walk?

Well, at least we do now, and of course our listeners do too!
