SpaceX Falcon 9 rocket landed at Cape Canaveral Air Force base

SpaceX has launched an unmanned cargo ship to the International Space Station on Monday, which it later turned around and landed at the Cape Canaveral Air Force base.
The 23-story-tall Falcon 9 rocket blasted off from Florida at 04:45 GMT.
Perched on top of the rocket was a Dragon capsule filled with nearly 5,000 pounds of food, supplies and equipment, including a miniature DNA sequencer, the first to fly in space.
As the Dragon cargo ship began its two-day journey to the station, the main section of the Falcon 9 booster rocket separated and flew itself back to the ground.
SpaceX has been developing rockets that can be refurbished and re-used, with a prime objective of slashing launch costs substantially.
