The second qualification flight of Ariane - 5(V502) will carry an atmospheric Reentry Demonstrator(ARD) which is a simple unmannedcapsule - type vehicle.
Last year, SpaceX became the first commercial aerospace company to successfully launch, place into orbit and retrieve a spacecraft -- the Falcon 9, carrying an unmannedcapsule called the Dragon.
The unmanned version of that capsule is designed to carry six tonnes of goodies for the inmates of the space station, or could be replaced by a heavy satellite.
