So the latest I've read says that the harpoons didn't deploy - meaning that they're not sure if Philae is now anchored to the comet or not. Not being anchored would be a bit of a problem.
Anyway, here are some photos I found. Didn't see them posted.

Am I the only one that thinks this looks eerily similar to the Space Invaders game from the old school Atari system?

Things aren't looking good for Philae. It seems that when it first hit the comet, neither the harpoons nor the foot screws engaged. So the probe bounce off the surface - probably a few hundred meters off the surface. While in this position, the comet rotated under it so that when it finally settled back down, it was no longer in the optimal position.
This is important since the original site was chosen to give it the most sunlight for charging it's batteries. In it's current position, it looks like it will only get about 1.5hrs of sun during each 12 hour rotation, which won't be enough.
Beyond that, since the probe isn't anchored, it may not be possible to drill into the comet without sending the probe back into orbit around it.

I think that slide is either wrong or I can't find the official gravity numbers of the comet but what I've been seeing is that on the comet a = 10-3 m/s^2. Compared to Earth, a=~10 m/s^2, which means its weight is equivalent to 10g. Still a small number but a power of 10 off.

AFAIK Philae is still asleep.

I believe the upper half of the mosaic is not right...

I'm thinking for the first time that thing looks like a barbell weight. At some point, it's going to break into two pieces. I wonder what will happen to it as a comet then?
Just one of those mysteries of the universe, and now we have a front row seat!

Simply amazing. I'm still amazed after all this time. Until this mission, I never imagined a comet would look so much like an asteroid....and with it's own impact craters too.
