Covering the business and politics of space
Ampac-ISP Corp., a wholly-owned subsidiary of American Pacific Corporation (Nasdaq: APFC – News), reported that their LEROS 1b thruster successfully completed a 524-second burn for the Mercury MESSENGER spacecraft on December 12, 2005, putting the solar-powered spacecraft on track for its first scheduled flyby of Venus in October 2006. This maneuver, known as Deep Space Maneuver 1 (DSM 1) is the first firing of the LEROS 1b for this mission, which started in August 2004 with its launch aboard a Delta II rocket from Cape Canaveral. MESSENGER (Mercury Surface, Space Environment, Geochemistry, and Ranging) is the seventh mission in NASA’s Discovery Program, and will study Mercury’s atmosphere, topography and elemental makeup. The engine will be fired at least five more times to place the spacecraft in orbit around Mercury. “We are proud to provide this key propulsion component as a member of the Mercury MESSENGER team,” said Robert Huebner, Vice President, AMPAC-ISP Operations. “The successful firing of the LEROS 1b underscores the reliability and effectiveness of our rocket engines.”
The LEROS 1b is a 645N class Hydrazine/NTO bipropellant thruster that was first qualified in 1995 and has been flying on telecommunications and military missions since 1996. The LEROS 1b was also used on the Mars Global Surveyor and Mars Odyssey spacecraft for major mission maneuvers.
The LEROS 1b was developed and is manufactured at AMPAC-ISP’s Westcott, United Kingdom division, with final testing at our Niagara Falls, New York facility. The LEROS 1b combines high thrust with high specific impulse (318 lbf-sec/lbm) to meet the control authority needs and provide thrust margin for heavy payloads and deep space probes. More than seventy (70) LEROS 1 series engines have been delivered since 1991 and all have performed flawlessly. A LEROS 1 engine provided the impulse needed for major orbital maneuvers during the mission to the asteroid Eros for the NEAR Mission.
