SpaceX launches reused Dragon capsule to International Space Station

SpaceX has launched its first recycled cargo ship to the International Space Station.

An unmanned Falcon rocket lifted off Saturday from Florida's Kennedy Space Centre with a Dragon capsule that made a station delivery nearly three years ago. When this refurbished Dragon reaches the orbiting lab Monday, it will be the first returning craft since the now-retired shuttles.

The same capsule is back for take two after a few modifications and much testing.

The first-stage booster used Saturday is new, but as is now the custom, will attempt to return to Cape Canaveral following liftoff. It's all part ofSpaceX'slong-term effort to save money through reusability.

Besides the usual supplies, the2,721 kilogramshipment includes mice and flies for research.

The flight was delayed two days by thunderstorms.
