SpaceX and NASA announced that the propulsion organization designed to safely abort the upcoming crewed Dragon capsule — dubbed SuperDraco — has been successfully fired 27 times and completed development testing. The SuperDraco thrusters are scaled up versions of the modest Draco thruster used for maneuvering and docking command on the upper stages of the Falcon ix rocket, the upcoming Falcon Heavy, and the Dragon spacecraft. SuperDraco provides roughly 200x more thrust than its footling blood brother, and is designed for a variety of utilize-cases and capabilities. Each spacecraft volition be fitted with 8 SuperDraco thrusters, and each thruster provides roughly 1/9 the performance of a unmarried Merlin 1D. The Falcon-9 launches with nine Merlin 1D engines, to give you an idea of how the systems compare.

SuperDraco is a 3D printed engine that'due south designed to be throttled from 20% to 100% of thrust and can be restarted multiple times. The SuperDraco engines are going to be used to ensure that a crew capsule tin can abort a mission safely and either land or splashdown. Spacecraft that behave the SuperDraco organisation volition also take redundant parachutes to ensure that the crew's survival doesn't depend on a single machinery, and the SuperDraco engines have enough thrust to safely abort a mission even with one engine failure.

One of the unique capabilities of the SuperDraco is its power to perform what'due south known as "propulsive landing." When Curiosity landed on Mars in 2012, it was far besides heavy to perform aerobraking in the thin Martian atmosphere. NASA designed a rocket-powered hovercrane to perform the operation instead, and SuperDraco could perform a similar maneuver with a much heavier payload. The engine is designed to use a storable liquid propellant for fuel (meaning it doesn't need to be kept cryogenically cold). A video of the most recent examination firing is embedded below.

The extensive abort capabilities of the Dragon V2 passenger-rated capsule are a departure from NASA'southward traditional philosophy. The Space Shuttle may have been an icon of human exploration for thirty years, but it had express arrest capabilities, no crew ejection machinery, and no way to safely return a crew to Earth if a problem developed in orbit. The investigation into Challenger's destruction indicated that the crew survived the initial explosion and may accept been alive and conscious until the coiffure cabin slammed into the body of water at more than than 200 miles per hour, while at that place was no way to relieve Columbia's crew short of an emergency attempt to bring Atlantis to readiness (and that plan was not attempted).

NASA'south goal with the new Dragon V2 capsule and the crew module being worked on at Boeing is to avoid ever having to face such scenarios again and to safeguard against multiple failure modes that could lead to the death of a crew. The flexibility and adequacy of the new SuperDraco should help achieve that goal.
