Today the the full test firing of the first stage of the Ares-1 went off. This is the rocket that will get the future astronauts off the ground and is basically the same thing that the shuttle uses, but without the shuttle and tank. Again, this is one of those rockets that once lit - you fly - until it's done.
Interesting history behind this rocket. The segments have all flown before on the shuttle, including STS-1 way back in 1981 when Columbia first flew on it. (Click graphic for details).
