Philae is asleep now after sending all data and performing all planned experiments. It may wake up when conditions become right and the lander gets more sunlight as the comet approaches the sun.

Good luck, Philae, and sleep well.

They were able to turn it to get more sunlight. Looks like Philae is not yet dead.

All of the Twitter updates about Philae just went from being happy about maneuvers and receiving data to grim endings and voltage plummeting.

Also, they are using the drill to try and rotate the lab so solar pannels are better oriented ! Wow !

There are also good and important reasons not to release raw data immediately. It depends on the nature of the data, the nature of the research, and the source of the funding. What's needed is some sort of balance between openness and the rights of those actually conducting the research.
I would agree that I would be reluctant to share information that I worked hard to obtain only to have others benefit unjustly. But it seems unjust that information , meaningless on its own, isn't shared for reasons that don't involve safety or, possibly in this case, that they would convey misinformation or confusion. I also agree balance and rights must be observed and that probably does represent ESA's reluctance to release their property.

I just want to see it – now. :-D

Looks like craggy beach rock at the beach...only this beach is a looooong way off....

Excellent image though. Too bad about the harpoon failing...hope they can still continue well enough.

Hopefully a nice batch of raw data will arrive in six months. I'm more annoyed that the data that does come out is in JPEG format. I figure the morsels they release should at least be available as PNG or TIFF.

Pretty much. "Embargo" is the favored word, though.

didn't Stardust bring back primordial materials ? And it came down quite hard.

To me this appears the leg may have disturbed the ridge of material and compacted it . If so, it has the consistency of soft asphalt. It seems very fortunate to have ended upright on all three legs because what we learn from Rosetta will attest or repudiate what role the next generation of comet explorations become.
Could you imagine the excitement of a cup of comet would bring back on Earth? I hope that would feel more like a home run than a run home that ebola fears arose. As it looks - Rosetta has destiny written all over it.

You said it yourself. You are ignorant. I suggest you do some reading.

So it does. That's why we have to be very careful in how we interpret images. We are easily fooled. It is wise to maintain a high degree of skepticism about our interpretations of imagery, especially imagery from an unfamiliar environment. It is the nature of our brains to force what we see into narrow patterns of experience, and that simply doesn't work in a case like this. Heck, that might not even be rock that the antenna isn't embedded in!
To me it looks more like the CONSERT antenna is serving as a foot in this picture while the foot that was supposed to support Philae is not touching anything the way it should be. The surface is very bumpy and Philae is sideways so the picture is quite disorienting. So, not necessarily embedded, but it definitely looks to be touching. Philae's mass on this comet is light enough that it could rest on one's fingertip.

Here's one for you: "oscillations in the magnetic field in the comet's environment"

And just for insight, what does that rock next to the lander look like? Too-dry concrete, right?

Looks embedded in he rock !? Look at the shadow how it comes out of the tip of it. If you are right, then the antenna is touching the rock.
