Rosetta mission: Potential comet landing sites chosen (BBC)
By Jonathan Amos
Science correspondent, BBC News
Europe's Rosetta mission, which aims to put a robot on Comet 67P/Churyumov-Gerasimenko, has identified five potential locations for the touchdown.
The choice of sites was driven largely by operational considerations - they are places engineers believe a lander can get down with the least risk.
No-one has attempted to land on a 10-billion-tonne comet before.
The Rosetta probe will despatch its Philae contact robot to 67P's icy surface on 11 November.
The European Space Agency says it will be a one-shot opportunity.
