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 tonne 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 tonne second stage, and a five-segment version of the SRB in the first stage. A conventional 'American' interstage was now shown.

  • Ares The design selected to boost America's Orion manned spacecraft into space in the 21st Century was a family of launch vehicles dubbed Ares. Originally sold as being derivatives of space shuttle technology, tinkering by NASA engineers and necessary changes during development quickly resulted in the designs being essentially all-new. After inevitable delays and cost escalation, the Ares was cancelled in 2010. More...

Ares I Chronology


2009 October 28 - . Launch Site: Cape Canaveral. Launch Complex: Cape Canaveral LC39B. LV Family: Ares. Launch Vehicle: Ares I.
  • Ares I-X - . Nation: USA. Agency: Clemson. Spacecraft: Ares. 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.
