The NASA Lewis Research Center and Primex Aerospace Company have developed a "green" monopropellant and thruster for replacement of the toxic hydrazine thrusters presently being used on most spacecraft. The thruster developed is a derivative of the Primex 1-lbf hydrazine MR-111C and operates on a hydroxylammonium nitrate (HAN)- based monopropellant. Initial thruster tests have resulted in a specific impulse of 195 sec and a density-specific impulse of 275 g-sec/cm3 (which is 25-percent greater than for stateof- the-art hydrazine thrusters).
