Also very interesting, if you look at the high-res picture and zoom at the bottom right, you'll notice some sort of cable on the ground/boulder. This could be the cable from one of the harpoons that may have fired but didn't anchor themselves, or it could be a feature attached to Philae that's in the field of vision.

It looks like it's resting on one of the antennae. You can see its shadow underneath it.

You know I have some bad days some times, but seeing shit like this just makes me think "What a fucking time to be alive!" It's truly incredibly and is sometimes that kick in the pants I need to keep on going. We are living in a golden age of humanity right now, at no point before in human history have so many people had such an incredible quality of life and never before has man been doing such incredible feats and…

Yes it is golden age as long as you disregard percentages and trend. "Some 805 million people in the world do not have enough food to lead a healthy active life. That's about one in nine people on earth." http://www.wfp.org/hunger/stats Economy seems like a boiler ready to explode, rich-poor chasm is widening like hell. Global peace doesn't look very rosy either. Not to mention what's happening on the environmental f…

The wealth gap can be misleading too, since the quality of life for those at the 'bottom' is often better than it ever has been on just about every metric you care to consider.

That's a great achievement in any case. I'm just slightly worried from the looks of this picture that Philae actually stabilized on its side. Also the large amount of shadow in the area is worrisome for the solar panels to function properly. Press conference with the release of a full panorama (which will hopefully not confirm the side landing) is scheduled for 1400 CET.

The sunlight appears to be coming from behind and to the left of Philae in this picture, at a fairly low angle, so the back of it should (I hope) be reasonably illuminated at the moment. It's definitely not clear from this picture which way is "up". It looks to me like up may be towards the top right of the picture, in which case Philae may be at a 45 degree angle. But I'm probably wrong - the full panorama should te…

After staring at the image a lot more, I realised I'm completely wrong. The leg reveals which way the lighting is coming from - above, slightly to the left, and probably slanting slightly into the camera. So my original interpretation of the orientation cannot be correct.

The real question is whether the picture should be rotated 90+ degrees clockwise.

To get an idea of the scale of the thing, here is a picture of the comet relative to the size of London :

I had no idea the thing was so small. To get something to intercept an object that size traveling at 1000's mph is an amazing feat!

Does it have a colour camera? or maybe it's a bandwidth-saving decision to transmit only B&W? or because of the lighting?

The pictures taken by Rosetta are BW. From [0]: "Some light contrast enhancements have been made to emphasise certain features and to bring out features in the shadowed areas. In reality, the comet is extremely dark -– blacker than coal. The images, taken in black-and-white, are grey-scaled according to the relative brightness of the features observed, which depends on local illumination conditions, surface characteristics and composition of the given area. Some slight vignetting can also be seen in the corners of some images." So possibly Philae has a similar system. [0] https://www.flickr.com/photos/europeanspaceagency/1573996637...
