The ''Johannes Kepler'' ATV, or Automated Transfer Vehicle 002 (ATV-002), was an unmanned cargo spacecraft built to resupply the International Space Station (ISS). It was launched on 16 February 2011 by the European Space Agency (ESA).〔 ''Johannes Kepler'' carried propellant, air and dry cargo weighing over ,〔(NASA's Consolidated Launch Schedule ). Retrieved 22 March 2012.〕 and had a total mass of over , making it, at the time, the heaviest payload launched by the ESA. The spacecraft was named after the 17th-century German astronomer Johannes Kepler. ''Johannes Kepler'' was the second ATV cargo resupply vehicle to be launched, following the ''Jules Verne'' mission of 2008. ''Johannes Kepler'' carried around five tonnes more cargo than Russia's Progress-M resupply spacecraft, and about 1.5 tonnes more than the Japanese HTV. The ATV used of fuel to boost the ISS's altitude from 350 to 400 km.〔 Many of the supplies aboard the ATV were used for the Space Shuttle mission STS-133 and the ISS Expedition 26.〔 A Reentry Breakup Recorder was placed aboard the ATV before it undocked from the ISS on 20 June 2011. ''Johannes Kepler'' performed a destructive re-entry as intended on 21 June 2011, with its remains impacting the Pacific Ocean. ==Spacecraft== ''Johannes Kepler'' consisted of two sections: the Propulsion Module, with four main engines and 28 smaller maneuvering thrusters, and the Integrated Cargo Carrier, which attached directly to the ISS and could hold up to eight standard payload racks.〔 The four solar wings of the spacecraft provided up to 4,800 watts of electrical power to its rechargeable batteries. The ATV's rendezvous and docking system mounted a telegoniometer, which functioned as a radar system, and two videometers, which fired laser pulses at cube-shaped reflectors on the ISS' ''Zvezda'' service module for range detection. The nose of the spacecraft contained rendezvous sensors and Russian docking equipment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Johannes Kepler ATV」の詳細全文を読む スポンサード リンク
