Could nuclear thermal propulsion take us to Mars?
Illustration of a Mars transit habitat and nuclear propulsion system that could one day take astronauts to Mars. Nuclear thermal propulsion technology provides high thrust and twice the propellant efficiency of chemical rockets.
How much power will it take to travel to Mars?
Future Mars transfer vehicles will need around 400kW-2 megawatts of power to successfully ferry our astronauts or cargo to and from the Red Planet. We’re still exploring vehicle and propulsion concepts for Mars, including a combination of nuclear electric and chemical propulsion and other emerging options like Nuclear Thermal Propulsion.
What is the propulsion system of Mars Orbiter?
Mars Reconnaissance Orbiter used a monopropellant propulsion system: there was fuel (hydrazine), but no oxidizer. Thrust was produced by passing the fuel over beds of catalyst material just before it entered the thruster, causing the hydrazine to combust.
How much propellant was used in the Mars orbit insertion maneuver?
More than 70 percent of the total propellant was used during just one maneuver — Mars orbit insertion. Some way was needed to push the propellant to the thrusters.
