The comet in 3D (and in French)


Grab your red-blue glasses;  this is a memorable 3D image.

ROLIS nous montre le noyau en relief

Here's the text, slightly mangled by Google Translate:

"Wednesday, November 12, ROLIS offered us moving images of the descent of Philae towards its landing site. The first was obtained just under 1 hour before the impact, and it showed the two lobes in perspective. Today, a relief assembly to better visualize this grand stage.

It took almost 2 minutes between the 2 images ROLIS (Rosetta Lander Imaging System) assembled to create this relief in sight. 2 min during which, Philae moved closer to the core of a little over 100 m, which allows us to admire a truly fantastic perspective.

You absolutely must find a pair of glasses with a red filter on the left and a green or blue filter on the right to appreciate the magnitude of this vision of another world. [Yeah, that's what I said.]

On the 1st level, within 3 km in Philae, the small lobe is brightly lit by the Sun which is on the right and the landing site Agilkia is practically in the center. In the distance, beyond the chaotic skyline of the small lobe, the cliffs of the large lobe appear much darker. The depth effect is accentuated by the presence in the top right of the image of a portion of one of the 3 feet of Philae which gives a human dimension to the scene.

In the lower part of the image, the small lobe, the "crater" Site B acquires a striking relief. It is all the more impressive that we know the sequence of events after 1 contact with the surface and we imagine the slow drift of Philae to the immense wall of this training, diving in a threatening darkness."

Pretty impressive for a dirty snowball, eh?
