SpaceX Grasshopper Rocket Hovers 820ft (320m) and Lands!

YouTube Description:

SpaceX's Grasshopper flies 820 feet, tripling its March 7th leap.

Grasshopper is a 10-story Vertical Takeoff Vertical Landing (VTVL) vehicle that SpaceX has designed to test the technologies needed to return a rocket back to Earth intact. While most rockets are designed to burn up in the atmosphere during reentry, SpaceX's rockets are being designed to return to the launch pad for a vertical landing.

I wonder why this is necessary. It seems all the planets we want to land on-and can land on b/c they're not made of gas or are on fire-have at least a little bit of atmosphere. It makes more sense to use parachutes and giant electric ducted fans or even heli rotors to land. Stop with the rocket fuel. And launch from the edge of space if possible.

Yeah, stupid rocket scientists.

Imagine a world where imported meats and cheeses can be rapidly delivered worldwide. No more semi-trucks or trains is what they're shooting for. These things are cleeearly being designed for terrestrial transportation of groceries....
