American heavy-lift orbital launch vehicle. Shuttle-derived launch vehicle design selected by NASA Administrator Mike Griffin to boost the manned CEV Crew Exploration Vehicle into low earth orbit. A single five-segment version of the shuttle solid rocket booster would be mated with a LOx/LH2 upper stage powered by a single J-2S engine.

In the initial September 2005 design the 160 metric ton upper stage was powered by an expendable version of the Shuttle SSME engine and supported by a Russian-type open Warren-truss interstage. A relatively unmodified single four-segment shuttle solid rocket booster would provide the first stage. By August 2006 the expense of the SSME and weight growth in the CEV forced NASA to switch to the J-2S engine powering a 127 metric ton second stage, and a five-segment version of the SRB in the first stage. A conventional 'American' interstage was now shown.

LEO Payload: 24,500 kg (54,000 lb) to a 160 km orbit at 28.00 degrees. Payload: 25,000 kg (55,000 lb) to a 350 km 51.6 deg orbit.

Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC39B. Launch Platform: MLP1. LV Family: Shuttle. Launch Vehicle: Ares I-X.
  • Ares I-X - . Nation: USA. Agency: Clemson. Spacecraft Bus: FLTP/FESTIP. Spacecraft: Ares spaceplane.

    First flight test of the Ares/Constellation program. The Ares I-X rocket consisted of the modified Shuttle RSRM-91A solid rocket booster, a dummy Upper Stage Simulator, and a dummy Ares command module / launch abort system. It was launched from the newly modified LC39B at Kennedy Space Center to test the aerodynamics of the vehicle within the atmosphere and provide real-world data to ameliorate concerns regarding the vibration level created by the SRB for any crew in a future mission. The SRB reached 46 km altitude before descending to the Atlantic for recovery.
