Down, on the surface, but maybe not safe. The anchoring system didn't fully engage. Philea weighs the equivalent of about 14 grams in that gravity. Any disturbance (like a nearby gas jet) could dislodge the thing and send it flying back off.

There's a press conference on the 13th that will reveal more. Hopefully one of the two systems to keep it attached is partially working.

What an incredible and astounding accomplishment this was.

Down and looking fairly safe.

What was science fiction becomes a reality, stunning achievement.

Did they ever get the anchors to fully deploy? Amazing technology.

No. Neither the harpoons or the leg screws worked. Not anchored at all. It finally bounced a couple times and kilometers from where it first hit and is now resting on its side. Correction to my above post -- it weighs 10 grams not 14 on the comet.

With no anchors it maybe a very short stay. It has no means to push against the comet with tools without launching itself off.

If it just sits there it should be ok I hope.

Batteries drained. Now in sleep mode. No more science can be done from the surface unless the comet gets closer to the sun and spins in a way that exposes the solar cells towards the sun from its awkward position. Some hope of that, but not much of a chance that it will happen.

Absolute certainty is will get closer to the sun, its closest encounter with the Sun is on 13 August next year. :)

This is not just a Philae mission the Rosetta orbiter still has plenty of planed work to do.

One jet erupts under the lander and it's off to deep space it goes. Let's hope it stays put or moves to a better location where they can try anchor it again
