The Constellation Program's Ares I-X test rocket roars off Launch Complex 39B at NASA's Kennedy Space Center in Florida.

With more than 12 times the thrust produced by a Boeing 747 jet aircraft, the Constellation Program's Ares I-X test rocket roars off Launch Complex 39B at NASA's Kennedy Space Center in Florida. The rocket produces 2.96 million pounds of thrust at liftoff and goes supersonic in 39 seconds.

Liftoff of the 6-minute flight test was at 11:30 a.m. EDT Oct. 28. This was the first launch from Kennedy's pads of a vehicle other than the space shuttle since the Apollo Program's Saturn rockets were retired. The parts used to make the Ares I-X booster flew on 30 different shuttle missions ranging from STS-29 in 1989 to STS-106 in 2000. The data returned from more than 700 sensors throughout the rocket will be used to refine the design of future launch vehicles and bring NASA one step closer to reaching its exploration goals.
