So you've got an iPad. What are you going to do with it? Read Twitter and Facebook? Watch YouTube?
Or explore deep space?
NASA, the kings of all things space, have just released an updated version of their iOS app for iPad. It features dashingly lovely graphics of the solar system and all the various planets, asteroids and comets that make it up - but also a guide to all the crap mankind has put up there over the years, with detailed graphics of satellites, space stations and probes.
So when you're at a pub quiz and you're asked in what year Galileo discovered Jupiter's moons, you can be quick with an answer. And, er, it also shows you where all NASA's bases are on Earth, less interestingly.
