## NASA eClips: Preparing to Launch Ares 1-X

 Real World: Preparing to Launch Ares I-X--- Now PlayingPreparing for future space missions, NASA is testing the Ares rockets prototype, Ares I-X. By finding the vehicles center of gravity, engineers can calculate the exact mass of the vehicle. The forces felt by the astronauts during launch are similar. Ares I-X Completes a Successful Flight Test NASA's Ares I-X test rocket lifted off Oct. 28, 2009, at 11:30 a.m. EDT from Kennedy Space Center in Florida for a two-minute powered flight. The flight test lasted about six minutes from its launch from the newly modified Launch Complex 39B until splashdown of the rocket's booster stage nearly 150 miles downrange. The 327-foot-tall Ares I-X test vehicle produced 2.6 million pounds of thrust to accelerate the rocket to nearly 3 g's and Mach 4.76, just shy of hypersonic speed. It capped its easterly flight at a suborbital altitude of 150,000 feet after the separation of its first stage, a four-segment solid rocket booster. Parachutes deployed for recovery of the booster and the solid rocket motor, which were recovered at sea and will be towed back to Florida by the booster recovery ship, Freedom Star, for later inspection. The simulated upper stage and Orion crew module, and the launch abort system will not be recovered. The flight test is expected to provide NASA with an enormous amount of data that will be used to improve the design and safety of the next generation of American spaceflight vehicles, which could again take humans beyond low Earth orbit
