Risky Space Travel - Danger in Space | SPACETIME - SCIENCE SHOW

SPACETIME - SCIENCE SHOW: Space, John F. Kennedy once said, is the new ocean. And for more than half a century now, man has been exploring this ocean. In doing so he is moving in a deadly environment characterized by cold, heat, and cosmic radiation. But one of the biggest dangers in space was put there by man himself: space debris poses a threat to astronauts and satellites. If one of these fragments were to hit the ISS, the international space station, it could have devastating consequences - even the demise of the whole crew. Hundreds of thousands of these fragments are hurtling through the Earth’s orbit at an estimated speed of eight kilometres a second, and every one of them could cause a disaster. Ever since space flight began man has also left his refuse behind in space. Satellites, spacecraft, and the International Space Station are permanently at risk of being hit, damaged, or even destroyed by particles of scrap. Astronauts are also at risk from cosmic radiation. Our sun, too, can mean death for humans in space.
