Update 9, 2:35 p.m.
A press briefing reviews what scientists currently know about Philae's condition:
It landed, and it landed in the right place.
The lander has power onboard, and it has been communicating with ESA mission control via radio waves.
The scientific instruments are working, and they're already sending back data, which scientists need more time to analyze.
Philae's harpoons did not fire, "so the lander is not anchored to the surface," said
Update 6: 11:50 a.m.
Oh ... While ESA has confirmed that Philae has touched the surface, it appears that the harpoons may not have fired to anchor it to the surface. Says ESA: "Without this anchor we cannot with 100 percent certainty state that we are landed on the comet and that we’re fixed on the comet... Everything is proceeding normally."
