SpaceX has made history by successfully launching a spaceflight from the same rocket used on two separate missions to orbit. The satellite was launched 22,000 miles into space, and the Falcon 9 rocket then returned to Earth and landed on a platform (known as a droneship) in the Atlantic Ocean.
This makes for the company's sixth successful landing on a seaborne platform.
The launch was a big step for SpaceX, who knows that recycling rockets is essential for driving down the cost of space travel. Because SpaceX's Falcon 9 rocket costs about $62-million, using it more than once can drastically cut the cost of a single launch.
