Today a member of the camera science team put up the first images of the comet on his office door. So the camera works. He said on the image is M107 and the comet could this be?

Hello again, Rosetta! Glad to see the cameras on Philae are checking out.

I talked to a few engineers today and they say they are in the middle of the Lander checkout.

At a member's suggestion I've now created a dedicated Rosetta subforum. This should now be the active thread for Rosetta discussion. Instrument commissioning is almost over and there hasn't been much discussion, so this thread may morph into the comet approach thread.
Everybody should be reading the Rosetta blog for detailed updates on the mission status; most are written by Emily Baldwin (Space Science Editor for ESA Portal, also @esascience). Including the attached new CIVA selfie, which is cooler in theory than in fact (it's low-res and awfully JPEGgy)

French organization CNES is also good source of news about Rosetta.
Here is for example color test image from Philae's ROLIS camera:  On the image is Rosetta's Multi Layer Insulation. Here is spectrum from Ptolemy:  -------------------- |

The "Big Burn" is going very well, according to the Big Burn twitter feed.

Eight hours??? Wow!
Could anyone in the know explain why they chose this strategy instead of a bunch of smaller burns done earlier? Is this perhaps an engine duty-cycle thing or something like that? EDIT: Or perhaps this is done now to facilitate a faster overall journey to the comet? -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

QUOTE (nprev @ May 21 2014, 04:25 PM)  ... perhaps this is done now to facilitate a faster overall journey to the comet? Looks like it to me. According to the Rosetta blog, the main purpose of the big burns is to reduce speed relative to the comet rather than just trajectory correction. So they are "braking" just before arrival. (As I understand it.) |
