Aerojet Rocketdyne developed a new MR-401 Low Thrust Rocket (LTR) for the GOES-R program that enables compliance with the unique GOES-R mission requirements. The GOES-R satellite has 16 of these MR-401 rockets onboard providing vehicle attitude control, momentum wheel desaturation and east/west stationkeeping. In addition to the 16 LTRs, Aerojet Rocketdyne also provided the 4.4kW MR-510 electric propulsion subsystem which provides all north/south stationkeeping for the GOES-R mission, as well as end of life decommissioning. The MR-510 Electric Propulsion (EP) subsystem consists of four MR-510 Arcjet thrusters, one 4.4kW Power Conditioning Unit (PCU), and the electrical harnessing to connect the PCU to the thrusters. The MR-510 EP system enables increased payload capability for the GOES-R mission due to the significant savings in propellant mass provided by the 3x improvement in fuel efficiency.ARDÉ, a subsidiary of Aerojet Rocketdyne based in New Jersey, provided the pressure vessels on the first and second stages of the launch vehicle. Built by Lockheed Martin, the GOES-R is a four-satellite program (GOES-R/S/T/U) and is a collaborative development and acquisition effort by NOAA and NASA. GOES-R will provide continuous imagery and atmospheric measurements of Earth's Western Hemisphere and space weather monitoring, resulting in more timely and accurate weather forecasts. It will improve support for the detection and observations of meteorological phenomena and directly affect public safety, protection of property, and ultimately, economic health and development. In addition to GOES-R, Aerojet Rocketdyne provides the same complement of flight hardware to GOES-S, GOES-T and GOES-U. Aerojet Rocketdyne is an innovative company delivering solutions that create value for its customers in the aerospace and defense markets. The company is a world-recognized aerospace and defense leader that provides propulsion and energetics to the space, missile defense and strategic systems, tactical systems and armaments areas, in support of domestic and international markets.
