期待著世界末日，阿波菲斯小行星來襲～

Доброе вечер（各位晚上好），我是伊琉沙 今天是公元2010年2月16日星期二 農曆1月3日（庚寅年。戊寅月。丁酉日） 稍晚剛剛在尖端科技2010.02.17[1110期]軍事電子報中看到了以下的新聞，覺得滿新鮮的！看過布魯斯威利的世界末日，未來也許真實世界也會發生！例外我也在Universe Today找到一樣的資訊。 俄羅斯太空機構規畫小行星偏移任務 Orbital path of Apophis. Credit: NASA NEO Program 美國聯合通訊社(Associated Press)2009年12月30日報導，俄羅斯聯邦太空局(RSA, Russian Federal Space Agency；Roscosmos)局長阿納托利‧貝米諾夫(Anatoly Perminov)表示，俄羅斯頂級太空研究人員將舉行一次閉門會議，計畫對編號為99942的阿波菲斯(Apophis)小行星進行偏移，該小行星將在20年後靠近地球。 貝米諾夫表示，阿波菲斯小行星大約是通古斯卡(Tungunsky)隕石的3倍大，通古斯卡隕石在1908年在西伯利亞爆炸，損毀了大約8000萬棵樹木。他說，據專家計算，現在還有時間設計太空飛行器在阿波菲斯小行星危險地飛向地球之前來改變其軌跡。 事實上，美國航空暨太空總署(NASA)在2009年指出，自從在2004年被發現後阿波菲斯撞向地球的機會已降低。 科學家們原來認為這個長270m，寬350m的小行星在2029年接近並撞向地球的概率為2.7%，但研究之後認為它仍會在地球上方29450km處。 其第2次靠近將發生在2036年，起初認為有1/45000的機率撞向地球，但現在可能性已降低到1/250000。 第3次接近發生在2068年，那時撞向地球的可能性為1/333000。 科學家們已提出不同的方法來避免小行星碰撞，其中是讓太空飛行器登陸小行星，且使用核子動力逐漸地改變小行星的軌跡。另一方法是用飛彈對小行星進行打擊，或部署1枚衛星利用萬有引力影響它改變軌道。 貝米諾夫指出，此計畫將不會包含「核武爆炸，一切都將以物理定律進行。」一旦確定任務，俄羅斯將邀請NASA、中國國家航天局(CNSA, China National Space Administration)和歐洲太空總署(ESA, Eropean Space Agency)參與。 外國專家對於貝米諾夫為何突然對小行星偏移任務感興趣感到迷惑，前阿波羅(Apollo)計畫太空人羅素‧史威查特(Russell Schweickart，Apollo-9/AS-504)說，阿波菲斯撞擊地球的機會非常小，以其檢驗偏移方法非常不可取，因為如果出錯將產生更大風險。 以下是Universe Today的在去年年底發佈的新聞 Russia May Head Mission to Deflect Asteroid Apophis December 30th, 2009 Written by Nancy Atkinson Russia is considering sending a spacecraft to deflect a large asteroid and prevent a possible collision with Earth, according to a radio interview by the head of the country's space agency. Anatoly Perminov said the space agency will hold a meeting soon to assess a mission to Apophis, and said NASA, ESA, the Chinese space agency and others would be invited to join the project. Apophis is a 270-meter (885-foot) asteroid that was spotted in 2004. It is projected to come within 29,450 kilometers (18,300 miles) of Earth in 2029, and currently has an estimated 1-in-250,000 chance of hitting Earth in 2036. A panel at the recent American Geophysical Union conference stressed that asteroid deflection is a international issue. "There is a geopolitical misconception that NASA is taking care of it," said former Apollo astronaut Rusty Schweickart, who is part of the B612 Foundation, which hopes to prove the technology to significantly alter the orbit of an asteroid by 2015. "They aren't and this is an international issue. The decisions have to be world decisions." Perminov seemed unaware that NASA's Near Earth Object program recently downgraded the possibility of impact in 2036 and also for a subsequent pass in 2068. Perminov said that he heard from a scientist that Apophis is getting closer and may hit the planet. "I don't remember exactly, but it seems to me it could hit the Earth by 2032," Perminov said. "People's lives are at stake. We should pay several hundred million dollars and build a system that would allow to prevent a collision, rather than sit and wait for it to happen and kill hundreds of thousands of people." Perminov wouldn't disclose any details of the project, saying they still need to be worked out. But he said the mission wouldn't require any nuclear explosions. "Calculations show that it's possible to create a special purpose spacecraft within the time we have, which would help avoid the collision without destroying it (the asteroid) and without detonating any nuclear charges," Perminov said. "The threat of collision can be averted." Boris Shustov, the director of the Institute of Astronomy under the Russian Academy of Sciences, hailed Perminov's statement as a signal that officials had come to recognize the danger posed by asteroids. "Apophis is just a symbolic example, there are many other dangerous objects we know little about," he said, according to RIA Novosti news agency.
