If you plan to make a space capsule that can land softly on Earth without using a parachute, you're going to need some pretty reliable rocket engines. So the privately funded SpaceX has just tested their brand spanking new SuperDraco engine, designed just for this task.
The engine will be used in SpaceX's emergency Launch Abort System (LAS), to shoot the capsule up off the main rocket and land it safely back on the ground. Eight SuperDracos will be used on the capsule, and all can be stopped or restarted in less than 1/10th of second for maximum control.
Hmmm, with a healthy 15,000 pounds of thrust, just one of these might be the perfect thing for souping up your road car.
