A space travel company founded by Tesla's Elon Musk has launched its first recycled rocket.
SpaceX's Falcon 9 rocket blasted off from Florida's Kennedy Space Centre on Thursday evening on the historic re-flight.
The launch is the biggest leap yet in the company's bid to drive down costs and speed up flights.
It's the first time Musk has tried to fly a salvaged booster.
The rocket initially landed on an ocean platform almost a year ago after a launch for NASA.

SpaceX refurbished and tested the booster, which still has its original engines.
The booster will aim for another sea landing once it hoists a broadcasting satellite for the SES company of Luxembourg.
