Save the James Webb Space Telescope

Lawrence Krauss has written an excellent defense of the James Webb Space Telescope, the successor to Hubble which is currently under threat of cancellation. I was really down on the space shuttle the other day, but that's because I think it was a failure at doing its job of enabling exploration and discovery — the Space Telescope is a fabulous tool that works, and I want NASA to focus more on cost-effective, powerful methods of exploring the universe.

Lawrence Krauss also criticized the space shuttle, and urges us to send more robots into space. Uh-oh. Cue ominous music as Neil deGrasse Tyson emerges from the wings, carrying a folding chair.
