Philae landing successful!

So, Philae has landed!  We shot a bullet at a bullet and it hit!  Not everything is going exactly as planned, however.  The thruster meant to counteract the harpoons' recoil was not functioning before separation, but the team went ahead anyway.  Now, it appears the harpoons themselves did not fire.  While gravity is enough to hold Philae to the comet for now, when the there is more activity closer to the sun, it may no longer be.  The harpoons are essential for securing Philae to the main body of the comet.

Despite all this, here's another great picture Philae took during descent.  The landing gear appears in the upper right (no, that's not a UFO).

UPDATE: At a press briefing just now, it appears that Philae may have rebounded a bit.  The radio link was fluctuating, though consistently re-linked.  Some data showed that Philae was rotating for a bit, then stopped rotating.  All of this would be consistent with Philae landing, rebounding, then landing again.  For the coming hours, Rosetta (our only link to Philae) is below the horizon, so there is no radio link.  This particular loss of link was planned and expected, so there is nothing to be concerned with in this regard.
