The Automated Transfer Vehicle (ATV)

The International Space Station (ISS) depends on regular deliveries of experimental equipment and spare parts as well as food, air and water for its permanent crew. From early 2008 onward, Europe's Automated Transfer Vehicle (ATV) will be one of the indispensable ISS supply spaceships.
 
Every 12 months or so, the ATV will haul 7.7 tonnes of cargo from its Kourou launch site in French Guiana to the Station 340 km above the Earth. An on board high precision navigation system will guide the ATV on a rendezvous trajectory towards ISS, where it will automatically dock with the Station's Russian service module. The ATV will remain there as a pressurized and integral part of the Station for up to six months until its final mission: a fiery one-way trip into the Earth's atmosphere to dispose of up to 6.4 tonnes of Station waste.
