Space junk

Available for over a year

This week on Tech Life we are looking at the problem of space junk, the man-made debris hurtling around our planet. Could it threaten some of the everyday tech we all rely on? Also this week, don't you just hate it when stuff doesn't work? Are internet and social media outages becoming more frequent ? A doctor in Argentina has created a video game to help calm the nerves of children facing a hospital operation. And what weighs three tonnes and is the size of a mini-van ? It's the world's largest digital camera. Presenter: Chris Vallance Producer: Tom Quinn (Photo: A NASA illustration of space debris around Earth. Credit: Nasa/Getty)
