Elon Musk has done it again. This time by achieving a revolutionary feat; the “lateral divert test.”

The Grasshopper is a reusable launch vehicle that is designed to go out into space and return to Earth with a vertical landing. This would ultimately make space exploration cheaper, more accessible and convenient.

In a video publicized by Musk via his Twitter account, SpaceX’s Grasshopper rocket went 250 meters (820 feet; about 75 stories high) into the air, and then turned sideways 100 meters (328 feet) before realigning itself to the base and landing back down on the launch pad.

It’s a huge milestone for SpaceX, whose ultimate goal is to be able to leave and return to Earth. Although they had vertical landing down-packed, it was important to be able to move sideways to achieve this.

The vehicle’s ability to perform more aggressive steering maneuvers than have been attempted in previous flights,” SpaceX said in a statement. “Diverts like this are an important part of the trajectory in order to land the rocket precisely back at the launch site after re-entering from space at hypersonic velocity.”

Aside from SpaceX, Musk has been busy making headlines with Tesla Motors,  replaced Oracle on the Nasdaq 100 in July, his release of the 57-page plan for the open source Hyperloop project, and his subtle hints that he’d create a supersonic jet “if someone else doesn’t.”
