In the latest issue of Astronomy and Astrophysics
http://www.aanda.org/articles/aa/abs/2007/.../aa8272-07.html -------------------- 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.

QUOTE After its successfull launch on 2 March 2004, the spacecraft will fly by (2867) Steins in September 2008 at a distance of 1745 km with a relative velocity of 8.5 km/s Cool, another asteroid explored from a close distance! |

And yet another to come afterwards. Rosetta will flyby 21 Lutetia in July 2010. Lutetia will be the largest asteroid visited by spacecraft until Dawn reaches Vesta in 2011.

Of course, we will be seeing the first images from the Steins flyby shortly before NH reaches Pluto, followed by several unprocessed, raw snapshots of Lutetia around the time NH makes its other KBO encounter...

WOW!
That means that Mars images taken this year will be released soon after the end of next year? -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

Well, we will probably get an image or two at the time of the flyby, but I agree with your time table for everything else. -------------------- |

In Astronomy & Astrophysics this week
Are the E-type asteroids (2867) Steins, a target of the Rosetta mission, and NEA (3103) Eger remnants of an old asteroid family? -------------------- 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.

Here's a snapshot of a poster presented at DPS, showing how they have determined the flyby location & distance for the Steins encounter. Neat stuff. --Emily

The grammar police tell me that they screwed up 'less' and 'fewer.'
 Thanks for the poster image... sounds like it will be a really good look. |
