Philae: 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.

After two bounces, the first one about 1km back out into space, the lander settled in the shadow of a cliff, 1km from its target site.

It may be problematic to get enough sunlight to charge its batteries.

The BBC's science editor David Shukman reports.
