Description: The Orbital Sciences Corporation Minotaur I is a four-stage launch system that couples components from retired Minuteman II Intercontinental Ballistic Missiles (ICBM) with upper stage components of commercial Pegasus rocket. This approach ensures Minotaur remains a low-cost launch vehicle which has demonstrated a 100 percent rate of success. Minotaur I are available only for the United States of America (USA) government payloads. The first launch of the Minotaur I was carried out in January 2000. The USA through the NASA and the MDA has ordered Minotaur I, Minotaur II and Minotaur III space rockets to put a variety of payloads into orbit or test missile defenses (ABM). As of September 2013, the Minotaur has logged 10 launches, the Minotaur II 8 launches and the Minotaur III number of launches has not been disclosed.

The Minotaur I utilizes the first (M55) and second (SR19) stages rocket motors from the Minuteman II ICBM and two boosters at the upper stage (Orion 50XL and Orion 38). The resulting rocket can put payloads of up to 580 kg into Low Earth Orbit (LEO). The Minotaur II is a suborbital three-stage rocket used to test missile defense. The Minotaur III is a suborbital three-stage rocket designed to test missile defenses or to delivery payload of up to 6,500-lb at suborbital altitudes. The Minotaur I launch vehicle scored another success on 11 April 2005 putting into polar orbit XSS-11 a self-maneuvering micro-satellite for Air Force Research Laboratory (AFRL). XSS-11, weighing 220-pound, was aimed at demonstrating micro-satellites maneuverability capability which could revolutionize the way space satellites do business.
