Europe launches its first re-supply spaceship – Jules Verne ATV – to the International Space station
Jules Verne, the first of the European Space Agency’s Automated Transfer Vehicles (ATV), a new series of autonomous spaceships designed to re-supply and re-boost the International Space Station (ISS), was successfully launched into low Earth orbit by an Ariane 5 vehicle this morning. During the coming weeks, it will manoeuvre in order to rendezvous and eventually dock with the ISS to deliver cargo, propellant, water and oxygen to the orbital outpost.On this first ATV mission, Jules Verne will deliver 4.6 tonnes of payload to the ISS, including 1 150 kg of dry cargo, 856 kg of propellant for the Russian Zvezda module, 270 kg of drinking water and 21 kg of oxygen. On future ATV missions, the payload capacity will be increased to 7.4 tonnes.
Named after the famous French 19th century visionary and author, the Jules Verne ATV is the largest and most sophisticated spacecraft ever developed in Europe, combining the functions of an autonomous free-flying platform, a manoeuvrable space vehicle and a space station module. About 10 m high with a diameter of 4.5 m, it weighed 19,357 kg at launch. It incorporates a 45-m3 pressurised module, derived from the Columbus pressure shell, and a Russian-built docking system, similar to those used on Soyuz manned ferries and on the Progress re-supply ship. About three times larger than its Russian counterpart, it can also deliver about three times more cargo.
The ATV is also the very first spacecraft in the world designed to conduct automated docking in full compliance with the very tight safety constraints imposed by human spaceflight operations. It features high accuracy navigation systems and a flight software far more complex than that used on Ariane 5. About half of the payload onboard Jules Verne ATV is re-boost propellant, which will be used by its own propulsion system for periodic manoeuvres to increase the altitude of the ISS in order to compensate its natural decay caused by atmospheric drag. Upon leaving, after four months spent docked to the ISS, Jules Verne ATV will carry away waste from the Station. It will then be de-orbited over the Southern Pacific Ocean and burn up in the atmosphere in a fully controlled manner.
