As Emily pointed in her twitter, data from Lutetia flyby are now available.
Here is folder for NAC calibrated images. And Here is folder for WAC calibrated images. NAVCAM images are available too, but shape of Lutetia is only barely recognizable in best of them. This is little sample, "raw" image of Lutetia from distance 4008 km (converted by img2png and improved by enhancing local contrasts):

QUOTE (Ian R @ Apr 7 2012, 05:39 PM)  And here's a flyby video: awesome! thanks for sharing! -------------------- I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

Excellent!
I'm now burning DVD with Lutetia flyby images, and I had few MB of free space, so I added your animation to this collection.

I have been awaiting a nice color image of Lutetia before updating my asteroids-and-comets montage to make a color version / poster. Looking forward to what you guys produce!
Ian, your video is terrific! -------------------- |

I did some color images and stereograms of Lutetia from published raw images:

Stefan:
I flipped images according to documents in ESA's archive, but I suppose, that you are right. Maps of Lutetia are based on your orientation, but I realised this after my blog post. Still, then I prefer more this orientation: EDIT:I changed orientation of all images in my blog post, so now they aren't from mirror universe. Thanks for notice!

I've decided to re-process the flyby animation using calibrated images, adjusted to remove the 'flickering' caused by the multi spectral nature of the dataset:

ESA made a flyby movie of it's own, it would appear. Lots of other good stuff in the text. |
