Rosetta: concerns for comet lander after uneven landing

After a historic but awkward comet landing, the robot probe Philae is now stable and sending pictures – but there are concerns about its battery life.

The lander bounced twice, initially about 1km back out into space, before settling in the shadow of a cliff, 1km from its intended target site.

It may now be problematic to get enough sunlight to charge its battery systems
