This is starting to get interesting.

Imagine taking a 10-story building, launching it, angling it so that it shifts 330 feet to the side as it rises 820 feet into the air – and then landing it on the same spot it started.

That is essentially what the rocket scientists at Space Exploration Technologies Corporation, the company commonly known as SpaceX, did on Tuesday in their latest effort to
develop a rocket that can be used again and again. Currently rockets are used just once, with the first stage disintegrating as it falls back to Earth. This bothers Elon Musk, the chief executive of SpaceX, who likens it to building a 747, flying it cross-country and then throwing it away.
