The effects of external tank disposal by retrorocket versus passive tank drop, and targeting the main engine burn for high apogee versus the baseline parking orbit ascent method on shuttle payload accommodation capability were investigated. Missions launched from Eastern Test Range were investigated over a range of orbit altitudes to determine tank disposal requirements including footprint dispersions and alternate impact locations, performance, and orbital maneuvering system requirements. Passive tank drop also proved to be advantageous from a payload accommodation standpoint. Direct insertion was shown to be a means of accommodating long payloads at higher altitudes than permitted by the baseline ascent method. (Author)
