Default comet lander

it's a cool idea, but i'm not sure how you land on something the size of london's heathrow airport that is several light minutes away. obviously gravity can't help much, which (in my mind) leaves some mad piloting skills! how do they plan to find within a few meters where this thing is, much less land on it?

don't get me wrong, i love the idea. just not sure how it can work...

It similar to the landing of Near/Shoemaker on Eros some time ago. Both comet and probe will be in the same orbit, so relative velocity will be vary slow. The rendezvous is tricky, but I guess the landing is merely a matter of patience.

The picture on CNN is not Rosetta. Check out

This was a wonderful mission, not sure it got as much publicity as it deserved.
