2007 Chinese anti-satellite missile test

<h2 id="background">Background</h2>
During the 1999 <a href="/facts/NATO_bombing_of_Yugoslavia/QscqBsCW">NATO bombing of Yugoslavia</a>, the <a href="/facts/United_States_bombing_of_the_Chinese_embassy_in_Belgrade/aywktkRX">United States bombed the Chinese embassy in Belgrade</a>.<a class="footnote-ref" id="fnref:18" href="#fn:18">18</a>: 16–17  The US stated that the bombing was accidental.<a class="footnote-ref" id="fnref:19" href="#fn:19">19</a>: 17  Chinese leadership believed that the US had intentionally bombed the embassy and viewed China as significantly lacking in leverage against the United States.<a class="footnote-ref" id="fnref:20" href="#fn:20">20</a>: 17  Among other efforts to reduce its gap in leverage such as developing cyberwarfare capabilities, China began to develop its counterspace abilities.<a class="footnote-ref" id="fnref:21" href="#fn:21">21</a>: 17 
In January 2001, a US congressionally mandated space commission headed by <a href="/facts/Donald_Rumsfeld/nTbFApTY">Donald Rumsfeld</a> recommended that "the US 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 US interests."<a class="footnote-ref" id="fnref:22" href="#fn:22">22</a> Moreover, the subsequent US withdrawal from the <a href="/facts/Anti-Ballistic_Missile_Treaty/zVdq5BYF">Anti-Ballistic Missile Treaty</a> in 2002 allowed the United States to pursue missile defenses, including those that were space-based.<a class="footnote-ref" id="fnref:23" href="#fn:23">23</a>
In response to the actions by the US towards potential space weaponization, the Chinese started developing their own anti-satellite missiles.<a class="footnote-ref" id="fnref:24" href="#fn:24">24</a> The 2007 test was part of a broader approach of strategic substitution to develop leverage from "information age weapons" instead of nuclear weapons.<a class="footnote-ref" id="fnref:25" href="#fn:25">25</a>: 1 

<h2 id="weaponry">Weaponry</h2>
The Chinese anti-satellite system was named by Lieutenant General <a href="/facts/Michael_D._Maples/Kf51JXWA">Michael Maples</a> (then Director of US <a href="/facts/Defense_Intelligence_Agency/lo2KYneo">Defense Intelligence Agency</a>), in a Senate Armed Services Committee Hearing, as the SC-19.<a class="footnote-ref" id="fnref:26" href="#fn:26">26</a> The SC-19 has been described as being based on a modified <a href="/facts/DF-21/Ag5XmXzo">DF-21</a> <a href="/facts/Ballistic_missile/Pl6juY73">ballistic missile</a> with a <a href="/facts/Projectile/kaDpG3N7">Kinetic Kill Vehicle</a> mounted. The ASAT kill vehicle relies on an imaging infrared seeker and also has been described as a modified <a href="/facts/HQ-19/sxeD7Xwo">HQ-19</a> with a KT-1 rocket booster.<a class="footnote-ref" id="fnref:27" href="#fn:27">27</a> The program is said to have been at least partially funded by China's <a href="/facts/863_Program/yoxs62qw">863 Program</a> (specifically, the 863-409 focus area).<a class="footnote-ref" id="fnref:28" href="#fn:28">28</a>
The closing velocity of the intercept was approximately 8 kilometers per second (17,900 mph), comparable to the American <a href="/facts/National_Missile_Defense/v1omy7IC">National Missile Defense</a> system.<a class="footnote-ref" id="fnref:29" href="#fn:29">29</a>

<h2 id="aftermath">Aftermath</h2>

<h3>Political reactions</h3>
Several nations responded negatively to the test and highlighted the serious consequences of engaging in the <a href="/facts/Militarisation_of_space/93ajBK7v">militarisation of space</a>. Chinese Foreign Ministry spokesman <a href="/facts/Liu_Jianchao/0blTzhJ2">Liu Jianchao</a> stated, "There's no need to feel threatened about this" and argued that "China will not participate in any kind of <a href="/facts/Arms_race/o8nvYPVu">arms race</a> in <a href="/facts/Outer_space/R3LRKyFs">outer space</a>."<a class="footnote-ref" id="fnref:30" href="#fn:30">30</a><a class="footnote-ref" id="fnref:31" href="#fn:31">31</a> China had publicly been advocating to ban space weapons, which had been rejected by the United States under <a href="/facts/George_W._Bush/mYSgM515">George W. Bush</a> because of certain loopholes in the treaty.<a class="footnote-ref" id="fnref:32" href="#fn:32">32</a><a class="footnote-ref" id="fnref:33" href="#fn:33">33</a>
The United States had not tested an anti-satellite weapon since 1985. In February 2008, the US <a href="/facts/Operation_Burnt_Frost/rpUygWTA">launched its own strike to destroy a non-functioning US satellite</a>, which demonstrated the capability to strike in space, though at a much lower altitude than the Chinese test. The US claimed that the strike was not a military test but a necessary mission to remove the threat posed by the decaying orbit of a faulty spy satellite with a full tank of <a href="/facts/Hydrazine/G7P5ITzU">hydrazine</a> fuel.<a class="footnote-ref" id="fnref:34" href="#fn:34">34</a>
In early 2013, the Russian concept satellite <a href="/facts/BLITS/syo9XKIp">BLITS</a> collided with what is believed to be a piece of debris from Fengyun-1C, was knocked out of its orbit and soon afterwards data retrieval from the satellite ceased.

<h3>Space debris tracking</h3>
Further information: <a href="/facts/List_of_space_debris_producing_events/hSuwnDaC">List of space debris producing events</a>
Anti-satellite missile tests, especially ones involving kinetic kill vehicles as in this case, contribute to the formation of orbital <a href="/facts/Space_debris/X7YSKlXl">space debris</a> which can remain in orbit for many years and could interfere with future space activity (<a href="/facts/Kessler_syndrome/DeBeFoto">Kessler syndrome</a>).<a class="footnote-ref" id="fnref:35" href="#fn:35">35</a> The 2007 Chinese ASAT test created the largest field of <a href="/facts/Space_debris/X7YSKlXl">space debris</a> in history, with more than 3,000 pieces of trackable size (golf ball size and larger) officially catalogued in the immediate aftermath, and an estimated 150,000 debris particles.<a class="footnote-ref" id="fnref:36" href="#fn:36">36</a><a class="footnote-ref" id="fnref:37" href="#fn:37">37</a><a class="footnote-ref" id="fnref:38" href="#fn:38">38</a> As of October 2016, a total of 3,438 pieces of debris had been detected, with 571 decayed and 2,867 still in orbit nine years after the incident.<a class="footnote-ref" id="fnref:39" href="#fn:39">39</a>
More than half of the tracked debris orbits the Earth with a mean altitude above 850 kilometres (530 mi), so they would likely remain in orbit for decades or centuries.<a class="footnote-ref" id="fnref:40" href="#fn:40">40</a> Based on 2009 and 2013 calculations of solar flux, the <a href="/facts/NASA_Orbital_Debris_Program_Office/qcvvLIBl">NASA Orbital Debris Program Office</a> estimated that around 30% of the larger-than-10-centimeter (3.9 in) debris would still be in orbit in 2035.<a class="footnote-ref" id="fnref:41" href="#fn:41">41</a>
In April 2011, debris from the Chinese test passed 6 kilometres (3.7 mi) away from the <a href="/facts/International_Space_Station/VNPUBz9m">International Space Station</a>.<a class="footnote-ref" id="fnref:42" href="#fn:42">42</a>
As of April 2019, 3000 of the 10,000 pieces of space debris routinely tracked by the US military as a threat to the International Space Station were known to have originated from the 2007 satellite shoot down.<a class="footnote-ref" id="fnref:43" href="#fn:43">43</a>

<h3>Unofficial or indirectly related responses</h3>
Desmond Ball of the <a href="/facts/Australian_National_University/fqzCfrdp">Australian National University</a> while commenting on China's anti-satellite (ASAT) test of January 2007 said: “China's ASAT test of 11 January involved a fairly primitive system, limited to high-inclination <a href="/facts/Low_Earth_orbit/rq1TwayJ">LEO</a> satellites. It is the sort of capability available to any country with a store of MRBMs/IRBMs or satellite launch vehicles, and a long-range radar system, such as Japan, India, Iran and even <a href="/facts/North_Korea/Q41laakP">North Korea</a>. However, its LEO coverage does include some extremely valuable satellites, including imaging and ELINT satellites, and the test is likely to generate reactions in several countries”.<a class="footnote-ref" id="fnref:50" href="#fn:50">50</a>
