Study of manned orbiting research laboratory (MORL) is based on mass estimates for subsystems necessary for 1 yr mission in circular orbit at altitude of 200 nautical miles; total impulse is based upon continuous thrust requirement of 0.10 lb frozen; electrical energy required is supplied by photovoltaic system; hydrogen is recommended propellant; with 14 engines, total mass of arc-jet system is approximately 7258 lb maximum; by comparison, stored-chemical propulsion system with specific impulse of 300 sec has mass of 11,790 lb maximum; this represents launch mass saving of 38% for arc-jet system.
