Aerojet Rocketdyne and Solar Electric Propulsion

Great article on Aerojet Rocketdyne’s push for Solar Electric Propulsion to enable deep space delivery of cargo, payloads and habitats. NASA has said that “SEP may deliver the right mix of cost savings, safety and superior propulsive power ”

Current list of Spacecraft using electric propulsion

“Approximately 75 percent of the mass required for human missions to Mars can be transported using SEP, thereby reducing the number of launches required. Additionally, the SEP systems under development now by NASA and Aerojet Rocketdyne can reduce the amount of propellant needed for deep space missions by a factor of 10.”

  1. Robert Clark says:

    A reduction by a factor of 10 in the propellant required is a big deal since most of the mass of the mission is just propellant. For instance if a Mars mission were to be 1,000 tons, most of which is just propellant, then we could reduce this to 100 tons, launchable by a single SLS.


    Short travel times to Mars now possible through plasma propulsion.
