What went wrong with probe landing?

Space scientists are working hard to stop the battery from running out on the first ever probe to land on a moving comet.

The solar-powered Philae probe is in the shadow of a cliff edge after bouncing almost a mile back into space and landing a kilometre away from where it should have.

European Space Agency experts say the historic probe has stabilised and begun to send its first pictures back from the surface of comet 67P.

But the bad landing has damaged the craft and its current location means the battery that powers it may not be able to recharge.

Here the BBC's space expert David Shukman explains to Newsround what went wrong with the landing.
