More than three tons of cargo are now at the International Space Station after the SpaceX Dragon supply craft docked there today. The docking is the first autonomous docking for SpaceX.
The craft will remain at the space station for about a month. Cargo in the craft includes science investigations and a new airlock.
The rocket that docked is a new, upgraded Dragon design that has more powered lockers for science and research storage for transport to and from Earth.
