Take a ride to the edge of space with space shuttle Atlantis, following along with cameras mounted to the solid rocket boosters, then watch as they disengage and free fall all the way back to Earth.
NASA's solid rocket boosters perform a fairly magnificent feat every time they chaperon one of the shuttles into orbit, but the fact that they detach, free fall only to be recovered, rebuilt, then reused is significant. As our space program slowly starts to show its age, we can only hope that reuse technology is designed into the next age of space exploration vehicles.
