Elon Musk's SpaceX reached a milestone in reusability yesterday when it successfully relaunched a segment of one of its Falcon 9 rockets.
The Californian company flew a first-stage booster that was previously used on a mission 11 months ago, and Musk called it a "huge revolution" in spaceflight.
Rocket segments are typically thrown away or destroyed after one use, but SpaceX aims to reuse Falcon first-stages to reduce the cost of operations.
The rocket launched from Florida's Kennedy Space Center at 6.37pm EST and approximately 32 minutes later deployed its telecommunications satellite into orbit.
It then securely landed on a barge stationed out in the Atlantic.

"I think it's an amazing day for space," said Musk. "It means you can fly and re-fly an orbit class booster, which is the most expensive part of the rocket. This is going to be, hopefully, a huge revolution in spaceflight."
SpaceX said the mission, SES-10, marks a "historic milestone on the road to full and rapid reusability as the world’s first reflight of an orbital class rocket".
Watch the launch
SpaceX has successfully launched and landed eight of its 13 attempts. Last year, an explosion of one of its rockets destroyed Facebook's first ever satellite.
