The first test flight of NASA’s crew launch vehicle Ares 1 will use a four-segment solid-rocket booster for its first stage, not the five-segmentd esign specified in the aseline requirement. Ares 1’s current design uses a Space Shuttle-derived five-segment SRB first stage and a new liquid-oxygen/liquid-hydrogen Rocketdyne J-2X-powered upper stage.

The first Ares 1 test is due in April 2009.
