Philae: 'It's done what it went there to do'
The Philae lander on the distant comet 67P has sent another stream of data back to Earth before losing power.
Everything expected from the little probe was delivered, just before low battery power dropped it into standby mode.
The robot is shadowed by a cliff and cannot get enough light on to its solar panels to recharge its systems.
Astrophysicist Elizabeth Pearson says although the future of the lander is uncertain, the orbiter Rosetta is the workhorse of the mission and its work will carry on.
