In the olden days of science fiction, the iconic space ships were silvery cigars that took off and landed standing upright on their four stabilizing tail vanes.


With the ongoing improvements to Space-X's Grasshopper rocket, we're getting ever nearer to realizing this early vision of a reusable vehicle.


Using precision control systems, Grasshopper has been steadily increasing its climbs and returning gently to the launch pad.  If Space-X succeeds in perfecting this system, they will be able to greatly decrease the expense of launching payloads into orbit.
