Continue exploring Mars and learn about asteroids in this video of class 6 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.

There is really cool geology being explored on large, oddly shaped asteroids. The Near Earth Asteroid Rendezvous (NEAR) mission reached 433 Eros in 2000, and one of the exciting results was the discovery of features called "ponds".

253 Mathilde is the largest asteroid that has ever been visited by a spacecraft. It's held that distinction for more than twelve years, but next year it'll be upstaged by the considerably larger 21 Lutetia, which Rosetta will fly by on July 10.
