SpaceX rocket crashes into barge after failed landing

A SpaceX rocket has crashed into a floating ocean platform, after hitting it too hard following an attempted landing.

The first-stage booster rocket was returning to earth after helping fire a shipment of groceries to the International Space Station.

It apparently landed too hard on the barge and tipped over.

SpaceX has been hired by space agency Nasa to supply the ISS after the retirement of the space shuttle.

The company will try again in June on the next supply run.
