ATV-4 is the Automated Transfer Vehicle operated by the European Space Agency (ESA) to resupply the international space station (ISS) with propellant, water, air and dry cargo. After 10 days in orbit it docked to the ISS on 15th June 2013.
The Ariane 5 ES (Evolution Storable) has an estimated LEO launch capacity of 21,000 kg (46,000 lb). It includes all the performance improvements of Ariane 5 ECA core and boosters but replaces the ESC-A second stage with the restartable EPS used on Ariane 5 GS variants. It was used to launch the Automated Transfer Vehicle (ATV) into a 260 km circular low Earth orbit inclined at 51.6° and has been used 3 times to launch 4 Galileo navigation satellites at a time directly into their operational orbit. The Ariane 5 ES flew 8 times from 2008 to 2018 with no failures.
The Albert Einstein ATV, or Automated Transfer Vehicle 004 (ATV-004), was a European unmanned cargo resupply spacecraft, named after the German-born physicist Albert Einstein. It was built to supply the International Space Station (ISS) with propellant, water, air, and dry cargo, and also to reboost the station's altitude with its thrusters. It was the fourth and penultimate ATV to be built, following the Edoardo Amaldi, which was launched in March 2012. Albert Einstein's components were constructed in Turin, Italy, and Bremen, Germany, and underwent final assembly and testing in Bremen in 2012. The spacecraft left Bremen for Kourou on 31 August 2012 to begin launch preparations.Automated Transfer Vehicle (ATV) Details
