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.

The unusually high albedo measured with both polarimietry and with brightness + thermal infrared data (we need Spitzer measurements) really does seem to put this rock in the "e" category. I don't know how sure they currently are that this corresponds to rare and "weird" Enstatite chondrites. Is it the enstatite chondrites that have nearly identical oxygen isotope systematics to Earth and Moon rocks?

ANY opportunity to get a good look as something besides variations-on-a-theme of S type asteroids is extremely welcome. The only totally limited look we have of one is NEAR's nice flyby sequence of C type Mathilde, but it's just a nice sequence of pictures, mostly.

The short 6-hour rotation rate of Steins will help get some rotational coverage, like Gaspra and Ida.

What exactly will the closest approach distance to 2867 Steins be? I'll settle for an order-of-magnitude number if the distance is not precisely known yet.

Flyby September 5, 2008, at 1700 kilometres.

And earlier still:

February 2007 - Rosetta Mars flyby (200km altitude)
