The ATV uses up to 4.7 tonnes of propellant to raise the ISS altitude which naturally decreases with the residual atmospheric drag. In combination with ESA's new Ariane 5, 8.5 m-long Automated Transfer Vehicle (ATV) will enable Europe to transport cargo to the International Space Station. The 45 m³ pressurized module of the ATV delivers up to 7.2 tonnes of equipment, fuel, food, water and air for the crew.
