I think a commenter on Slashdot said it best:
Each time NASA releases images from some distant planet or asteroid, I'm floored. The number of things that have to go right, that have to not fail, millions of miles away, is immense. Kudos to the scientists and engineers who worked on imaging Vesta. Fantastic results!
