A robotic arm on the International Space Station has reached out to grab the visiting Dragon supply vessel. The arm will shortly move the ship to a free berthing port on the underside of the orbiting platform.
Dragon has been built by the California firm SpaceX and is carrying half a tonne of food and other stores for the ISS astronauts.
It is the first time a private sector company has attempted to deliver freight to the station.
