- Orion_abort_modes abstract "NASA's newest spacecraft, the Orion Crew Exploration Vehicle (CEV), will be the first spacecraft since Project Apollo to utilize an escape system in the event of a launch abort, something its predecessor, the Space Shuttle, had for only its first four orbital test flights in 1981-1982. Like the Apollo Command-Service Module (CSM), the Orion CEV will utilize the Launch Abort System (LAS), a solid-fueled tractor rocket that will be able to pull the Orion crew module away from a malfunctioning Ares I rocket during the initial launch phase until solid-fueled first stage is jettisoned. Based on the launch escape system found on the Soviet/Russian Soyuz spacecraft, the LAS, designed and manufactured by ATK for the Orion CEV, will be larger than the Soyuz version and will have more thrust than the Atlas 109-D booster that carried astronaut John Glenn into orbit in 1962.The earlier Apollo system had various abort modes depending on altitude, velocity, and other circumstances. Likewise the Orion will have similar modes of operation for its launch performance aborts. Some of these may not use the LAS itself, but would utilize the second stage of the Ares I, or even the Orion vehicle's own propulsion system (the Aerojet AJ-10 engine) instead.Initially designed to land on solid ground, like that of the early and current Soviet and Russian manned spacecraft (Vostok, Voskhod, and Soyuz), with a water landing as a backup, in August 2007, NASA tentatively redesigned the Orion for water landings (splashdowns) as the primary mode of landing, with ground landings as the emergency backup [1]. Under the advice of the Exploration Systems Architecture Study (ESAS) report, NASA will most likely develop abort procedures that resemble the abort procedures used on Apollo, but with some procedures carried over from the Shuttle.".
