When rockets go fast, they break the sound barrier. And when the sound barrier breaks, we get the Prandtl–Glauert singularity. That's the official term for the beautiful cone of vapor that forms around a craft moving very, very fast through the atmosphere. And it makes for a great photo.

NASA successfully tested a launch abort system that can eject astronauts away from a launch pad disaster. It's the alternate escape system for the Ares rockets that are slated to launch astronauts to the space station and the moon, assuming that the Constellation program manages to survive the political turmoil surrounding budget overruns and engineering problems.

Next year, 33 years after its maiden flight, the space shuttle will retire. What happens after that has become subject to fierce debate within the space agency. The designated successor program, named Constellation, was the darling of previous NASA administrator Michael Griffin, but a new review now has the space agency looking elsewhere for a ride back into the firmament.
