Ares I was the crew launch vehicle that was being developed by NASA as part of the Constellation program.

The Ares I rocket was specifically being designed to launch the Orion Multi-Purpose Crew Vehicle. Orion was intended as a crew capsule, similar in design to the Apollo program capsule, to transport astronauts to the International Space Station, the Moon, and eventually Mars.

The first stage was to have been a more powerful and reusable solid fuel rocket derived from the Space Shuttle Solid Rocket Booster (SRB). Compared with the Solid Rocket Booster, which had four segments, the most notable difference was the addition of a fifth segment. This fifth segment would have enabled the Ares I to produce more thrust.

The upper stage, derived from the Shuttle's External Tank and based on the S-IVB stage of the Saturn V, was to be propelled by a single J-2X rocket engine fueled by liquid hydrogen (LH2) and liquid oxygen (LOX).The J-2X was derived from the original J-2 engine used during the Apollo program, but with more thrust (~294,000 lbf) and fewer parts than the original engine.

The Constellation program, including Ares I was cancelled by President Barack Obama in October 2010 with the passage of his 2010 NASA authorization bill.
