Dragon V2's revolutionary launch escape system, the first of its kind, will provide escape capability from the time the crew enters the vehicle all the way to orbit. Eight SuperDraco engines built into the side walls of the Dragon spacecraft will produce up to 120,000 pounds of axial thrust to carry astronauts to safety should an emergency occur during launch.
This system also enables Dragon V2 to land propulsively on Earth or another planet with the precision of a helicopter, making possible interplanetary trips that would otherwise be constrained by ocean landings.
Dragon V2 was designed from the beginning with astronaut safety and comfort in mind. The vehicle holds seats for 7 passengers, and includes an Environmental Control and Life Support System (ECLSS) that provides a comfortable environment for crewmembers.
With a minimal number of stage separations, all-liquid rocket engines that can be throttled and turned off in an emergency, and launch escape capability all the way to orbit, Dragon V2 will be capable of delivering American astronauts to the space station and beyond with incredible reliability.
