[Satellite TODAY 05-20-13] Rocket motor producer ATK has completed the first U.S.-based testing of the high performance green propulsion thruster technology for the NASA Goddard Space Flight Center. The testing was conducted at ATK Defense Group’s test facility in Elkton, Md., in April of 2013.

    The ATK test facility is capable of assessing high-fidelity performance and operability features of the HPGP thruster technology, which is intended to be used for a wide range of attitude control/space maneuverability propulsion.

    HPGP is a green propulsion alternative that provides increased performance over traditional hydrazine propulsion technology. By comparison, HPGP is significantly safer and more cost-effective in terms of storage, material handling, transportation and launch-site processing.

    "The collaboration of NASA GSFC and ATK to validate HPGP thruster technology enables the development of green propellant options, which hold promise for demonstrating higher performance, cost-effectiveness and the reduction of health and safety impacts to personnel and the environment," said Christyl Johnson, NASA GSFC deputy director for technology and research investments.
