The new Cygnus freighter has arrived at the International Space Station (ISS) carrying about 700kg (1,500lb) of food and other supplies.
Astronauts on the platform reached out with a robotic arm and grabbed the vessel at 11:00 GMT.
Cygnus is on a demonstration mission to prove its technology.
It is one of two commercial ventures seeded by Nasa to pick up America’s ISS re-supply requirements following the retirement of the space shuttles.
The new vehicle, developed by the Orbital Sciences Corporation (OSC), made its approach using a mix of GPS, inertial navigation and lidar.
