Asteroid mission is a go

NASA has reversed itself, restarting the $446 million Dawn mission to orbit Ceres and Vesta, two of the largest asteroids in the solar system.

The mission is well worth the money. Besides the scientific benefits of studying two of the largest chunks left over from the creation of the solar system, it will be another test of an ion engine, and thus one more step toward bootstrapping ourselves into a more permanent and widespread presence in space.
