ParachuteWe want a square parachute so we can glide the rocket to a
particular landing spot. One interesting idea is having the rocket land on a big
air bag (like stunt-men use for jumping out of buildings). Such an air bag could
be on land or in the ocean. Differential GPS is accurate enough to land the rocket
on the right spot. By having the airbag on the ground the
rocket can save the weight of landing gear. We could also have a smaller and
lighter parachute since we can tolerate a higher downward velocity.
