Third time’s the charm — hopefully. On the second try, SpaceX did finally manage to land a booster on a floating ocean platform, a critical improvement that could pave the way to an eventual successful landing that could revolutionize the space industry.

Elon Musk’s quest to make space travel more economical by developing reusable rockets rather than ones that are dumped into the sea continued with the latest launch of a Falcon rocket, and video shows it landing upright on the floating platform, named “Just Read the Instructions,” before tipping over and exploding, according to a Washington Post report.

On Twitter, Musk was frank: “Looks like Falcon landed fine, but excess lateral velocity caused it to tip over post landing,” he wrote.

It was the closest SpaceX has come so far to landing a rocket, which delivered supplies to the International Space Station. The video shows it successfully extending its landing gear as it descends toward the platform, although it is rocking back and forth on its way down and ultimately makes a lateral move upon touchdown that sends it tipping over.

It was the second attempt to land a rocket on the platform, with the January attempt also failing in much more spectacular fashion. Another try was scrapped due to conditions at sea.

If Musk’s SpaceX can get this right, it would save the company $54 million per launch by reusing the rocket.

The plan is to launch the second stage of the rocket about 50 miles up, cutting off the first-stage engine, which then flips on its axis using nitrogen boosters and begins its descent to Earth. The engines light against to slow down the rocket, and grid fins steer it toward the landing site. Once it nears the site, the legs are deployed, and the rocket lands on the platform at a maximum vertical speed of 20 feet per second.

It will have to hit a small target: the platform is just 300 by 170 feet.
