Automated Transfer Vehicle
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. Since its first mission in 2008 Europe's Automated Transfer Vehicle (ATV) has been indispensable to the International Space Station.
Every 12 months or so, ATV hauls 7.7 tonnes of cargo from its launch site in Kourou, French Guiana to the Station 340 km above the Earth. High-precision navigation systems guide ATV on a rendezvous trajectory to the International Space Station where it automatically docks with the Station's Russian service module. ATV remains there as a pressurised and integral part of the Station for up to six months until its final mission: a fiery one-way trip into Earth's atmosphere to dispose of up to 6.4 tonnes of Station waste.
