Well Rosetta isn't going to get to 67P/Churyumov-Gerasimenko (Chury) till 2014, but it's not to early to set up a thread. There are a bunch of earth fly-bys, a Mars encounter at 200km in 2007 and a few asteriod passes. Not to mention the mission to land on the comet itself.

Only another nine and a half years to go.

Interesting...

Also, I believe they will be observing Comet Tempel 1 during the Deep Impact encounter.

Rosetta will be able to add to the information on Mars methane/formaldehyde, according to this abstract (pdf file).

"It will be able to search for other minor species (CH4, H2CO...) and to study possible local variations..."

Here is a nice self-portrait of the back of one of rosetta's solar pannels taken by one of the 6 micro cameras on the Philae lander. Looks like the pictures of the surface from the lander are gonna be sweet.

For those that understand German this site has lots of info about the Rosetta mission:

Great news. Wonder which ones???

During the first earth flyby by Rosetta which took place on the 4th of March, ESA ran a competition to find the best ground based images of the spacecraft during closest approach. The winners were announced on Monday. A gallery of all images taken of the spacecraft is available here.

I remember reading that due to the large size of rosetta's solar panels there was the hope that the shape of the spacecraft migh be resolvable, alas, only one submitter claims to have resolved some structure.

Rosetta meanwhile took some excellent photos of the earth and moon during the encounter

This website gives details of two asteriod flybys:

5 sept 2008 - flyby at asteroid 2867 Steins
10 july 2010 - flyby at asteroid 21 Lutetia

NOTE: I've updated this post to include the hyperlinks given in the article for the asteroid biogs.

And I thought the seven years that Cassini took to get to Saturn was long. I don't know what I will doing 9 and a half years from now. It is definitely going to be worth the wait. The pictures look really sharp!

ESA’s comet chaser mission Rosetta took these infrared and visible images of Earth and the Moon, during the Earth fly-by of 4/5 March 2005 while on its way to Comet 67P/Churyumov-Gerasimenko.

Good news on the problem with the sticky thermal door covering the OSIRIS cameras -- a problem which ESA had indicated in two status reports starting in January, but about which I simply could not pry any information from them. (Even Mike A'Hearn -- who is a co-investigator! -- had only been told that it was "some kind of stickiness".) ESA's close-mouthedness is a serious pain in the ass.

However, judging from the latest status report, they seem to have finally developed a software fix for it (after one unsuccessful earlier try).

http://sci.esa.int/science-e/www/object/in...fobjectid=37534 :

"On 31 May a test of the OSIRIS door mechanism was carried out with the
presence of the PI team at ESOC. The purpose of this test was to
characterise the behaviour of the flight model, compare it with the test
results on the ground models and finalise the new software routines for the
control of the door to be uplinked on 14 June. The test was successful and
the OSIRIS team has already delivered the new software. ESOC is preparing
for next week's uplink and verification operations."

Postscript: they do plan to use the OSIRIS cameras -- along with all of Rosetta's other remote-sensing instruments -- to observe Tempel 1 during the Deep Impact collision.
