Artist's impression of the Automated Transfer Vehicle approaching the International Space Station. In combination with ESA's new Ariane 5, the 20.5 t, 8.5 m-long Automated Transfer Vehicle (ATV) will enable Europe to transport cargo to the International Space Station. This new vehicle, scheduled for its initial test flight in September 2004, can carry 9 tonnes of scientific equipment, general supplies, water, oxygen and propellant. Up to 4 t can be propellant for ATV's own engines to reboost the Station at regular intervals as atmospheric drag reduces the orbit. Developed under Aerospatialess prime contractorship, an ATV will be launched on average every 15 months as a means of ESA contributing to the Station's operating costs. It can remain docked for up to 6 months, during which time it will be loaded with Station waste before being undocked and flown into Earth's atmosphere to burn up.

Artist's impression of the Automated Transfer Vehicle approaching the International Space Station. In combination with ESA's new Ariane 5, the 20.5 t, 8.5 m-long Automated Transfer Vehicle (ATV) will enable Europe to transport cargo to the International Space Station. This new vehicle, scheduled for its initial test flight in October 2002, can carry 9 tonnes of scientific equipment, general supplies, water, oxygen and propellant. Up to 4 t can be propellant for ATV's own engines to reboost the Station at regular intervals as atmospheric drag reduces the orbit. Developed under Aerospatialess prime contractorship, an ATV will be launched on average every 15 months as a means of ESA contributing to the Station's operating costs. It can remain docked for up to 6 months, during which time it will be loaded with Station waste before being undocked and flown into Earth's atmosphere to burn up.
The ATV becomes an extension of the station. The 45 m� pressurized module of the ATV delivers up to 7,2 tonnes of equipment, fuel, food, water and air for the crew.
At almost 20 tonnes, the ATV will be the biggest spacecraft Europe has ever flown when it launches in January.
The Automated Transfer Vehicle is part-goods lorry and part-tugboat.
Its primary function will be to keep the International Space Station (ISS) stocked up with food, water, fuel and experimental equipment.
It will also re-boost the outpost, which has a tendency to drift down from its 300km-plus altitude as it brushes through the top of the atmosphere.
But the ATV is also a huge statement of capability. The maiden voyage will announce that Europe now has some important new technical competencies to rival the very best in the space exploration business.
"This is the most complex vehicle we have ever developed in Europe," said Jean-Jacques Dordain, head of the European Space Agency (Esa).
