Philae spacecraft lands on comet

[stevebowers]

The harpoons and thruster that should have secured it to the comet both failed, so it is relying on its weight to hold it down; this is about 15 grams, if my calculations are correct ( on the 'head' of the 'duck' it might be even less).

It will be really tricky to take any samples if it isn't anchored, and it may be upside-down or at any angle. Communications are really poor.
