ATK's Defense announced this week the successful completion of the first U.S.-based testing of High Performance Green Propulsion (HPGP) thruster technology for NASA Goddard Space Flight Center (GSFC).

HPGP is a green propulsion alternative that has been flight-proven in space to provide 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.
