The 2007 Chinese anti-satellite missile test was conducted by China on January 11, 2007. A Chinese weather satellite—the FY-1C polar orbit satellite of the Fengyun series, at an altitude of , with a mass of 750 kg—was destroyed by a kinetic kill vehicle traveling with a speed of 8 km/s in the opposite direction〔(Is China's Satellite Killer a Threat? (Tech Talk) ) 〕 (see ''Head-on engagement''). It was launched with a multistage solid-fuel missile from Xichang Satellite Launch Center or nearby. ''Aviation Week & Space Technology'' magazine first reported the test. The report was confirmed on January 18, 2007 by a United States National Security Council (NSC) spokesman.〔BBC News (2007). (Concern over China's missile test ). Retrieved January 20, 2007. 〕 At first the Chinese government did not publicly confirm whether or not the test had occurred; but on January 23, 2007, the Chinese Foreign Ministry officially confirmed that a test had been conducted. China claims it formally notified the U.S., Japan and other countries about the test in advance. It was the first known successful satellite intercept test since 1985, when the United States conducted a similar anti-satellite missile test using an ASM-135 ASAT to destroy the P78-1 satellite.〔 The New York Times, Washington Times and Jane's Intelligence Review〔 Or see archived version: (WebCite query result )〕 reported that this came on the back of at least two previous direct-ascent tests that intentionally did not result in an intercept, on July 7, 2005 and February 6, 2006.〔Joan Johnson-Freese. Heavenly Ambitions: America's Quest to Dominate Space. p. 12〕 A classified U.S. State Department cable revealed by Wikileaks indicates that the same system was tested against a ballistic target in January 2010 in what the Chinese government publicly described as a test of "ground-based midcourse missile interception technology". That description also closely matches the Chinese government's description of another test in January 2013 has led some analysts to conclude that it was yet another test of the same ASAT system, again against a ballistic target and not a satellite. == Background == In January 2001, a (US) congressionally mandated space commission headed by Donald Rumsfeld recommended that “the U.S. government should vigorously pursue the capabilities called for in the National Space Policy to ensure that the president will have the option to deploy weapons in space to deter threats to, and, if necessary, defend against attacks on U.S. interests." Moreover, the U.S. withdrawal from the Anti-Ballistic Missile Treaty in 2002 has allowed the United States to pursue missile defenses, including space-based. In response to US weaponisation of space, the Chinese started a space defense program, including anti-satellite defense.〔http://www.armscontrol.org/act/2005_12/DEC-CVR〕 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「2007 Chinese anti-satellite missile test」の詳細全文を読む スポンサード リンク
