- The addition of a restartable HAPS stage enables the deployment of spacecraft at multiple orbital altitudes, allowing unique mission tailoring and cost sharing among several small satellites requiring different orbits.
- The MPP enables the deployment of up to 12 small satellites, consisting of four ESPA-class satellites, four smaller secondary satellites and four P-POD carriers.
Orbital Sciences Corporation (NYSE: ORB), one of the world’s leading space technology companies, today announced that it successfully launched a Minotaur IV space launch vehicle in support of the U.S. Air Force’s Space Test Program-S26 (STP-S26) mission. In a launch that originated from the Kodiak Launch Complex in Alaska on Friday, November 19, 2010 at 8:25 p.m. (EST), the rocket carried four microsatellites and two CubeSats into low-Earth orbit approximately 405 miles (650 kilometers) above the Earth. The Minotaur IV was equipped with a hydrazine auxiliary propulsion system (HAPS) that acted as a fifth stage to reach a higher orbit, approximately 745 miles (1,200 kilometers) in altitude, demonstrating a new multi-orbit capability. The STP-S26 mission was the 19 th overall mission for the Minotaur product line over the last 10 years, all of which have been successful. “The third successful Minotaur IV flight in 2010, and the second in less than two months, builds on our well-established record of mission success for the Minotaur rocket family. We are proud to have supported the U.S. Air Force with the next generation of the Minotaur launch vehicle family for the STP-S26 satellite program,” said Mr. Ron Grabe, Orbital’s Executive Vice President and General Manager of its Launch Systems Group. “With three successful launches in its first year of operations, the Minotaur IV is proving to be a valuable new capability for the Air Force to meet its space launch needs.” The STP-S26 mission demonstrated a new capability for Minotaur IV, called the Multiple Payload Platform (MPP), which addresses the needs of small satellite customers. Several key facts about this new capability are as follows:
