是福还是祸? "中国成功实验弹道导弹摧毁卫星"
1) BBC
http://news.bbc.co.uk/2/hi/asia-pacific/6276543.stm US condemns China 'space weapon' The United States, Australia and Canada have criticised China over a weapons test it is said to have carried out in space last week. The Americans say the Chinese sent up a ballistic missile to destroy an ageing weather satellite. They say the test went against the spirit of co-operation both countries aspire to in the area of civil space. Reports say Britain, South Korea and Japan were expected to express their concerns to China soon. US National Security Council spokesman Gordon Johndroe confirmed a report in the magazine, American Aviation Week and Space Technology. The report cited space sources as saying a Chinese Feng Yun 1C polar orbit weather satellite, launched in 1999, was destroyed by an anti-satellite system launched from or near China's Xichang Space Centre in Sichuan Province on 11 January. The impact occurred at more than 537 miles (865km) above Earth. "The US believes China's development and testing of such weapons is inconsistent with the spirit of co-operation that both countries aspire to in the civil space area," Mr Johndroe said. "We and other countries have expressed our concern regarding this action to the Chinese." US space strategy Last October, the US adopted a tough new policy aimed at protecting its interests in space. The 10-page strategic document states that the US national security "is critically dependent upon space capabilities, and this dependence will grow". "The United States will preserve its rights, capabilities, and freedom of action in space... and deny, if necessary, adversaries the use of space capabilities hostile to US national interests," it says. The document rejects any proposals to ban space weapons. The White House said at the time that the policy did not call for the development or deployment of weapons in space. But its strategic paper addressed concerns - voiced in a 2001 Pentagon report that said technological advances would enable potential enemies to disrupt orbiting US satellites. During the Cold War, US President Ronald Reagan proposed a defence shield using laser or particle beam technology to "intercept and destroy" incoming nuclear missiles. The Strategic Defence Initiative, or "Star Wars" programme as it came to be known, was abandoned in 1993. 2) CNN HEADLINE http://edition.cnn.com/2007/TECH/spa...ile/index.html Tools: Save | Print | E-mail | Most Popular U.S. official: Chinese test missile obliterates satellite POSTED: 0325 GMT (1125 HKT), January 18, 2007 Story Highlights• Chinese use a missile to ram and destroy an old, orbiting satellite • Experts: China now may have ability to knock out U.S. GPS and spy satellites • Washington issues formal diplomatic protest Adjust font size: WASHINGTON (CNN) -- China last week successfully used a missile to destroy an orbiting satellite, U.S. government officials told CNN on Thursday, in a test that could undermine relations with the West and pose a threat to satellites important to the U.S. military. According to a spokesman for the National Security Council, the ground-based, medium-range ballistic missile knocked an old Chinese weather satellite from its orbit about 537 miles above Earth. The missile carried a "kill vehicle" and destroyed the satellite by ramming it. The test took place on January 11. (Watch why the U.S. has protested the missile strike ) Aviation Week and Space Technology first reported the test: "Details emerging from space sources indicate that the Chinese Feng Yun 1C (FY-1C) polar orbit weather satellite launched in 1999 was attacked by an asat (anti-satellite) system launched from or near the Xichang Space Center." A U.S. official, who would not agree to be identified, said the event was the first successful test of the missile after three failures. The official said that U.S. "space tracking sensors" confirmed that the satellite is no longer in orbit and that the collision produced "hundreds of pieces of debris," that also are being tracked. The United States logged a formal diplomatic protest. "We are aware of it and we are concerned, and we made it known," said White House spokesman Tony Snow. Several U.S. allies, including Canada and Australia, also have registered protests. Under a space policy authorized by President Bush in August, the United States asserts a right to "freedom of action in space" and says it will "deter others from either impeding those rights or developing capabilities intended to do so." The policy includes the right to "deny, if necessary, adversaries the use of space capabilities hostile to U.S. national interests." Low Earth-orbit satellites have become indispensable for U.S. military communications, GPS navigation for smart bombs and troops, and for real-time surveillance. The Chinese test highlights the satellites' vulnerability. "If we, for instance, got into a conflict over Taiwan, one of the first things they'd probably do would be to shoot down all of our lower Earth-orbit spy satellites, putting out our eyes," said John Pike of globalsecurity.org, a Web site that compiles information on worldwide security issues. "The thing that is surprising and disturbing is that [the Chinese] have chosen this moment to demonstrate a military capability that can only be aimed at the United States," he said. 3) CBC http://www.cbc.ca/world/story/2007/0...sile-test.html Canada voices concern over Chinese missile test Last Updated: Thursday, January 18, 2007 | 1:56 PM ET CBC News Canada, Australia and the United States told China on Thursday that they are upset that it conducted an anti-satellite weapons test involving a ballistic missile last week. "The United States believes China's development and testing of such weapons is inconsistent with the spirit of co-operation that both countries aspire to in the civil space area," U.S. National Security Council spokesman Gordon Johndroe said. "We and other countries have expressed our concern to the Chinese." The test destroyed an old Chinese weather satellite. U.S. intelligence agencies said they think China carried out the test on January 11. |

美国指责中国用弹道导弹摧毁一颗老化卫星 新文化网
据英国媒体消息,美国周四指责中国向太空发射了一枚弹道导弹,摧毁了一颗老化的气象卫星。 航空周刊杂志最先报道说,美国情报机构得出结论说,中国在1月11日成功地试验了一枚攻击卫星武器。 杂志还说该武器是一个由弹道导弹带入太空的“动能攻击载体” ,一个老化的中国气象卫星被此武器击毁。 美国表示,中国的太空试验违背了美中两国希望在太空民用领域进行合作的精神。 在华盛顿美国国家安全事务委员会的一个发言人说,澳大利亚和加拿大已经对中国此举表示关注,其它国家也可能发出同样批评。 |

"The Air Force in 2004 deployed the 76th Space Control Squadron, which can disrupt or knock out foreign satellites using electronic jammers from the ground." ================================================================== Moscow, Beijing eye space weapons By Bill Gertz THE WASHINGTON TIMES January 17, 2007 China and Russia are developing space weapons and are among several nations working on systems to threaten U.S. satellites with lasers or missiles, says the director of the Defense Intelligence Agency. In Senate testimony last week, Army Lt. Gen. Michael Maples for the first time raised Pentagon concerns about secret Chinese and Russian space weapons programs. "Russia and China continue to be the primary states of concern regarding military space and counterspace programs," Gen. Maples said at the annual threat briefing of the Senate intelligence committee. Gen. Maples said that "several countries continue to develop capabilities that have the potential to threaten U.S. space assets, and some have already deployed systems with inherent anti-satellite capabilities, such as satellite-tracking laser range-finding devices and nuclear-armed ballistic missiles." Other countries are working on improving space-object tracking and "kinetic or directed energy weapons capabilities." Gen. Maples did not discuss the reported testing of a Chinese anti-satellite laser against a U.S. satellite, which triggered high-level Bush administration worries about Beijing's growing space-weapons program. U.S. officials said details about the Chinese anti-satellite laser shot remain classified so as not to alert China about U.S. knowledge of what intelligence officials say may have been a test shot of an anti-satellite weapon. China has developed several types of ground-based lasers with Russian and Israeli technology, U.S. officials have said. Russia developed anti-satellite weapons during the Cold War, and U.S. officials think the Russian military is continuing work on the weapons, which include both anti-satellite missiles and ground-based lasers. Both Russia and China deny that they are building space weapons and have sought to curb U.S. space defenses through a proposed international ban on weapons in space. The Air Force in 2004 deployed the 76th Space Control Squadron, which can disrupt or knock out foreign satellites using electronic jammers from the ground. Nations other than Russia and China that have space capabilities in key areas also "will acquire military and commercial space-based assets," Gen. Maples said. "Increasing levels of international cooperation, along with the growing number of commercial space consortia, is allowing the proliferation of advanced satellite technologies and knowledge of space systems operations to become available to nations lacking a domestic space capability," he said. Gen. Maples said that building space weapons is "financially taxing" and that "most countries assessed to be pursuing these capabilities are not expected to acquire them within the next few years." He warned, however, that less-developed states and "nonstate entities" also "are pursuing more limited and asymmetric approaches that do not require excessive financial resources or a high-tech industrial base." |

中评社香港1月19日电,“汉和”杂志总编辑平可夫接受中央社记者电话访问时表示,从军事和政治角度看,这次事件的意义重大,包括: 一、中国在发展太空武器方面已真正迈向更高境界,而且是从实战用途加以发展,并在实践上取得进展。 二、这次事件绝对会刺激美国,因为美国一直把太空视为他们的后院,无人敢挑战;而既然中国已有真正的动作,美国未来可能会进一步研究太空战争的军事技术,而且主要针对中国─过去只针对前苏联。 三、可能会促成美国、俄罗斯和中国坐下来谈判太空的发展。到目前为止,各大国间关于如何和平利用太空只停留在理念阶段,只有意愿,没有国际法的约束。 这次事件固然可能导致大国间的太空军事竞赛,但也有可能促成大国间谈判把太空非军事化,最后签订条约。 四、事件说明中国的军事杀手(金间)愈来愈多,使中国的军事实力提升到更高层次。目前,全球只有美国有这种实力,即使英国和法国都做不到;俄罗斯有这种技术和潜力,但没有钱。至于印度,未来可能做得到,但目前与中国差距仍大,两国的宇宙发展已进入“不同档次”。 此外,平可夫认为,中国这次以导弹击落卫星,固然是中国朝着大国方向发展的必然趋势,但也有针对台海局势向美、日发出警示的味道。 他说,作为大国,中国愈来愈注意“第六代战争”。所谓的“第六代战争”,是指未来的战争将从击毁敌人在外太空的卫星开始。 再者,平可夫说:“连同上次高调宣传歼十战机,中国大有就台海局势向美、日警示的味道,告诉美、日他有更多的手段,希望藉此警告美日今年内不要介入台海局势。” 他说:“我想,针对台海局势,他(中国)可能还会有更多的动作。” 平可夫表示,中国的太空发展和美国还是有很大差距,但美国肯定会扩大利用这次事件。 但美国的真正反应,必须等待国防部的正式回应。 |
