The Automated Transfer Vehicle, originally Ariane Transfer Vehicle or ATV, was an expendable cargo spacecraft developed by the European Space Agency (ESA), used for space cargo transport in 2008–2015. The ATV design was launched to orbit five times, exclusively by the Ariane 5 heavy-lift launch vehicle. It effectively was a larger European counterpart to the Russian Progress cargo spacecraft for carrying upmass to a single destination—the International Space Station (ISS)—but with three times the capacity.
History The five ATVs were named after important European figures in science and engineering: Jules Verne, Johannes Kepler, Edoardo Amaldi, Albert Einstein, and Georges Lemaître. Following several delays to the program, the first of these was launched in March 2008. These ATVs performed supply missions to the ISS, transporting various payloads such as propellant, water, air, food, and scientific research equipment; ATVs also reboosted the station into a higher orbit while docked. The ATV was an uncrewed platform that operated with a high level of automation, such as its docking sequence; at no point was it used for transporting passengers.
Further use of the ATV was proposed in 2008. Various further developments, including crewed versions of the ATV as well as opportunities to reuse sections or elements of its technology, were studied by both the ESA and Airbus Defence and Space, the principal manufacturer of the vehicle. However, on 2 April 2012, the ESA announced that the ATV program would be terminated following the launch of the fifth ATV in 2014.
In 2012, ESA member states decided that the ATV design might be adapted to serve as the service module of the NASA Orion spacecraft. In January 2013, ESA and NASA announced that they would proceed with a combined Orion and ATV derived service module, later renamed European Service Module (ESM), which would serve as a major component for the Orion crewed spacecraft.NASA Signs Agreement for a European-Provided Orion Service Module NASA's Artemis I launched on November 16, 2022, carried the Orion spacecraft with the European Service Module (ESM) manufactured by Airbus Defence and Space for two planned low fly-by orbits to the Moon. ESA will provide the ESMs for the Artemis program up to Artemis VI with Artemis IV to provide the first humans to set foot on the Moon since 1972.
Development Origins During the 1990s, as the International Space Station program was taking place, it was collectively recognised by the 15 participating nations that, upon completion, the International Space Station (ISS), a crewed space station in Low Earth orbit (LEO), would require regular resupply missions in order to meet the needs of the onboard crew as well as to deliver apparatus to support the various scientific tests that would be performed on board. In October 1995, it was agreed that, amongst the various contributions to the ISS program that Europe would assume responsibility for under the auspices of the European Space Agency (ESA), one of them would be the Automated Transfer Vehicle, or ATV; this logistics-orientated spacecraft would perform the identified resupply missions to the ISS.Jeziorski, Andrzej. "Counting on Columbus." Flight International, 13 May 1998.
On 9 December 1998, the ESA awarded a $470 million contract to proceed with development work on the ATV to French aerospace company Aérospatiale. While Aérospatiale served as the principal contractor for the ATV, it was joined by multiple major subcontractors, including Italian manufacturer Alenia Spazio, Franco-British firm Matra Marconi Space and German aerospace company DaimlerChrysler Aerospace (DASA); some components were also provided by Russian firm S. P. Korolev Rocket and Space Corporation Energia. Prior to 2000, DASA was to serve as the prime contractor for production, after which the role would be gradually transferred to Aérospatiale. At the point at which the contract had been awarded, it was envisioned that the first flight of the ATV would be conducted during September 2003."European ATV gets go-ahead." Flight International, 9 December 1998."Special delivery." Flight International, 16 December 1998.
The launch of the first ATV, which had been named Jules Verne, was subject to multiple delays, which were partially generated by problems encountered with the Ariane 5 heavy-lift launch vehicle, as well as a substantial software re-write.Warwick, Graham. "Crystal gazing." Flight International, 4 January 2005."Ariane 5 ATV bay faces tough tests." Flight International, 7 June 2005. By May 2003, it was set to be launched sometime during late 2004.Furniss, Tim. "Ministers on European space rescue mission." Flight International, 13 May 2003.Furniss, Tim. "Face the facts with... Jean-Yves Le Gall." Flight International, 15 June 2003. By mid 2004, it had been announced that launch of the first ATV, which was by then undergoing electrical testing following the completion of integration work, had been postponed due to technical issues, and was reportedly scheduled to be launched during late 2005, following the issuing of a renegotiated $1.1 billion contract between the ESA and the prime contractor.Furniss, Tim. "ESA seals $1.1bn transfer vehicle deal." Flight International, 4 May 2004. In March 2005, another launch delay was declared, due to the need for greater development of the failure-mode software along with launch-window timing changes, which put the planned ATV launch back from late 2005 to an undetermined date during 2006.Coppinger, Rob. "Launch delay for ISS supply ship." Flight International, 22 March 2005."ATV launch delayed." Flight International, 12 July 2005. In October 2005, it was clarified that the new launch date for the first ATV would be during 2007.Coppinger, Rob. "ATV delayed to May 2007." Flight International, 18 October 2005.
In September 2006, it was announced that the final stage of testing on the Ariane 5's customised ATV stage was within its final phase.Coppinger, Rob. "Testing of upgraded Ariane's ATV stage enters final phase." Flight International, 19 September 2006. In December 2006, it was announced that the first ATV had completed its vacuum test, marking the successful completion of the key tests and enabling a final launch date to be set.Coppinger, Rob. "ATV vacuum test completed but launch date slips again." Flight International, 19 December 2006. In April 2007, the ATV was subject to four-month long qualification process in response to operational concerns, including safety queries originating from the U.S., and to examine the vehicle's potential commercialisation.Coppinger, Rob. "Qualification process to test ESA's ATV." Flight International, 20 March 2007.Coppinger, Rob. "NASA assesses ISS supply options." Flight International, 6 February 2007.
Production Following multiple restructuring and ownership changes,Jasper, Chris. "Astrium business to split into satellite and launcher arms." Flight International, 27 March 2001. the prime contractor for the ATV became Airbus Defence and Space, which led a consortium of many sub-contractors. While development work had been started in Les Mureaux, France, much of the activity relocated to Bremen, Germany, as the project moved from its development to the production stage, in which work on the four initial units started. In order to facilitate the relationship between the contractor and the ESA, an integrated ESA team at the Les Mureaux site was established and maintained for the duration of the development.
Airbus Defence and Space builds the ATVs in its facility in Bremen. In 2004, contracts and accords were signed for four additional ATVs, which were envisioned to be launched at a rate of around one every two years, bringing the total order, including the first, Jules-Verne, to five vehicles. According to the German Aerospace Center (DLR), the development cost of the ATV was approximately €1.35 billion. Reportedly, each ATV spacecraft was costed at roughly US$300 million, which did not include launch costs. In March 2005, RSC Energia signed a €40 million contract with one of the main subcontractors of Airbus Defence and Space, the Italian company Alenia Spazio (now Thales Alenia Space), to supply the Russian Docking System, refuelling system, and Russian Equipment Control System. Within the Airbus Defence and Space led project, Thales Alenia Space is responsible for the pressurized cargo carrier section of the ATV and manufactures these at the firm's facility in Turin, Italy.
On 31 July 2007, the first ATV, Jules Verne, arrived at the ESA spaceport in Kourou, French Guiana, after a nearly two-week journey from Rotterdam harbour. On 9 March 2008, Jules Verne was launched on top of an Ariane 5 rocket from Kourou.Coppinger, Rob. "Europe's cargo spaceship makes maiden flight towards space station." Flight International, 10 March 2008. On 3 April 2008, Jules Verne succeeded in automatically docking with the ISS, proving the capabilities of the ESA's first fully automated, expendable cargo resupply spacecraft.Coppinger, Rob. "ATV: An automatic success." Flight International, 1 April 2008.Coppinger, Rob. "ESA's cargo spaceship achieves automatic docking." Flight International, 7 April 2008. The arrival of the ATV came at a time at which there were public concerns over the logistical practicality of supplying the ISS."Science could be victim of ISS cargo pressure." Flight International, 3 June 2009.
In addition to its use by ESA and Russia, the ATV was at one point under consideration to perform services for NASA as part of the Commercial Orbital Transportation Services program to replace the retiring Space Shuttle in its orbital cargo carrying capacity. Under the proposal, which had been issued by a joint venture between EADS and Boeing, the ATV would be launched from Cape Canaveral, Florida, using a Delta IV rocket."Boeing set to offer Delta IV-launched ATV." Flight International, 12 April 2005.Sirko, Robert., Kevin Reyes and Jacques Breton. "Compatibility of Delta IV with the Transfer Vehicles HTV and ATV for Cargo Delivery." International Astronautical Federation, 2006. One speculated use for NASA's ATV was to achieve the de-orbiting of the ISS once the space station had reached the end of its service life, being the only vehicle capable of doing so at that time after the Shuttle's retirement."NASA may buy ESA's ATV to de-orbit ISS at end of life." Flight International, 3 July 2007. Ultimately, the proposal was not awarded with a corresponding contract.
Design The Automated Transfer Vehicle (ATV) was a 1990s-design expendable cargo spacecraft. Each vehicle consisted of two distinct sections, the systems bus and the integrated cargo carrier. The system bus contained the ATV's propulsion system, avionics bays, and solar arrays; it was principally used following the vehicle's detachment from the Ariane 5 launcher to automatically traverse the remaining distance and dock with the ISS, the system bus would be inaccessible to the astronauts on board. The integrated cargo carrier consisted of a pressurised module, external bays for fluid and gas cargoes, further avionics and rendezvous sensors, and the docking mechanism. The primary structure of the ATV (of Al-2219) is protected by a meteorite and debris protection system. The first ATV was built in the 2000s and the first one to fly in space was in 2008.
