NASA Perseverance’s Mission to Mars Propelled by Aerojet Rocketdyne
“Perseverance will rely on
Perseverance will launch aboard a ULA Atlas V rocket in the 541 configuration, employing a number of
- Four AJ-60A solid rocket motors manufactured in
Sacramento, California, are on the Atlas V’s first stage and will provide 1,394,000 pounds of thrust to lift the vehicle off the launch pad.
- A single RL10C-1 Centaur upper stage engine built in
West Palm Beach, Florida, will propel Perseverance on a trajectory to Mars after first stage separation.
- 12 MR-106 reaction control system thrusters made in
Redmond, Washington, will provide pitch, yaw and roll control for the Atlas V’s Centaur upper stage, as well as settling burns for the RL10 engine.
- Six tanks built by
Aerojet Rocketdynesubsidiary ARDÉ in Carlstadt, New Jersey, will store high pressure helium used to pressurize propellant tanks on the launch vehicle’s first and second stages to feed propellant to the engines.
- Two tanks also built by ARDÉ will store high pressure helium to pressurize the lander/descent propulsion system.
After the spacecraft separates from the Centaur upper stage, it will begin its roughly seven-month journey to Mars.
Once the Perseverance rover is safely on the surface of Mars, it will begin preparations for its roughly two-year sample collection mission.
