On Friday, February 15th an asteroid half the size of a football field will fly closer to the earth than the satellites that tell you when to turn left do! Should we all hit the panic button right now?
NASA is so sure that the world won't end on December 21, 2012 (which just happens to be this Friday) that they've already produced a video for the day after! So how can they be so sure, well they are smarter than the rest of us so we'll just have to trust them.
'Curiosity' is a car sized rover that NASA has just landed on the surface of Mars as they try to find signs that life once existed on Mars.
The mission was unprecedented, and easily the most difficult landing that NASA has ever attempted. The good news is that it was successful, and now the 'Curiosity' rover is sending back high def images from the surface of Mars.
