[Satellite TODAY 04-22-10] Alliant Techsystems (ATK) has shipped the Operational Responsive Space-1 (ORS) satellite bus to Goodrich Corp. for payload integration after completing environmental tests, ATK announced.
    ATK said the bus was shipped four days ahead of schedule in preparation for ORS-1’s launch later this year. 
    The satellite’s platform, built over a period of 16 months, is based on the design ATK developed for the TacSat-3 satellite, with the addition of a propulsion module. TacSat-3, launched in May, was the earlier demonstration program that led to ORS-1.
    The ORS-1 Program is managed by the U.S. Air Force’s Space Development and Test Wing.
