This was a tough one, and I sure didn’t see it. Here’s the original picture as posted this a.m.:
I’ve circled Philae:
And here’s the detail of the area I circled; this and the top picture come from Rosetta Blog via reader coel:
I think that at least one reader guess it correctly. The interesting blog post (read it) notes this:
The images were taken on 2 September by the OSIRIS narrow-angle camera as the orbiter came within 2.7 km of the surface and clearly show the main body of the lander, along with two of its three legs.
The images also provide proof of Philae’s orientation, making it clear why establishing communications was so difficult following its landing on 12 November 2014.
Yep, Philae bounced into a crack! No sun to power its batteries, and not much line of communication with Earth. Rosetta, however, is set to land on the comet as well, and we can expect more pictures soon:
The discovery comes less than a month before Rosetta descends to the comet’s surface. On 30 September, the orbiter will be sent on a final one-way mission to investigate the comet from close up, including the open pits in the Ma’at region, where it is hoped that critical observations will help to reveal secrets of the body’s interior structure.
