AKIPRESS.COM - Just before 6:30 pm ET, SpaceX -- run by Tesla (TSLA) CEO Elon Musk -- launched a used rocket. It marked the first time in the history of spaceflight that the same rocket has been used on two separate missions to orbit, CNN reported.

After successfully launching a satellite toward geosynchronous orbit -- 22,000 miles into space -- the rocket then returned to Earth and landed on a remotely piloted platform, known as a droneship, in the Atlantic Ocean. It was the company's sixth successful landing on a seaborne platform.

The SpaceX video showed the empty droneship, named Of Course I Still Love You, awaiting the return of the rocket, set against a deep blue ocean background. The video feed cut out momentarily and then came back on to show the rocket standing upright on the platform. The landing took place about eight minutes after launch.

Incredibly proud of the SpaceX team for achieving this milestone in space! Next goal is reflight within 24 hours.

"It shows you can fly and refly an orbit-class booster, which is the most expensive part of the rocket," Musk said on a SpaceX webcast. "This is ultimately a huge revolution in spaceflight."

And shortly after the landmark success, Musk took to Twitter to announce his next goal for SpaceX: To launch a rocket twice in 24 hours.

The launch was a huge step for SpaceX. Reusing rockets is essential for companies like SpaceX that want to drive down the cost of space travel.
