European space probe awakens for comet landing

European space probe Rosetta awoke from a deep sleep earlier this week to gear up for an unprecedented mission  - to rendezvous and land on a comet. In this week's Science Smart, Johanna Wagstaffe explains why this was such a huge milestone for space exploration in what has already been a highly choreographed mission. And what information they hope to find out once Rosetta makes it's landing in a few month.
