俄陨石事件持续发酵，俄宇航局正式递交20亿美元反陨石系 ...

俄罗斯陨石袭击事件持续发酵。美国国家航空航天局专家根据最新数据对周五在车里雅宾斯克地区坠落的陨石的各项数据做出调整，得出结论称，陨石比之前估算的结果大得多，由它引起的爆炸威力较此前认为的大得多，相当于1945年广岛原子弹爆炸威力的30倍。 陨石直径不是15米，而是17米，重达1万吨（此前的计算结果为7000吨）。

同时，俄宇航局昨天正式向俄总理府递交了价值20亿美元（）580亿卢布）的反陨石/小行星防卫系统计划。该反陨石/小行星系统主要由预警子系统和攻击子系统组成。

预警子系统的投资主要是用来安装或升级、联网分布在俄境内及全球的自动天文望远镜、雷达和计算通讯网络设备。而攻击陨石和小行星的子系统分为间接改变小行星轨道的先进软攻击武器和紧急情况下使用的直接攻击武器。

如果陨石或小行星被发现时已经离得太近，该系统将使用百万吨级的热核弹头导弹（氢弹）直接攻击陨石或小行星。如果发现的及时，该系统可以采用更先进的软攻击武器。



Russia to spend billions on asteroid defense

Moscow believes an operable national defense against threats from outer space can be built within 10 years’ time. The 500-kiloton explosion of a space bolide above the Urals region has sped-up allocation of some $2 billion to prevent future threats.

Russian scientists have presented a federal program designed to counteract space threats. Elaborated by the Institute of Astronomy at Russia’s Academy of Sciences and the Central Engineering Research Institute, Russia’s leading space industry enterprise, the program has already been approved by Roskosmos, the national space agency.

The program has nothing to do with Hollywood sci-fi movie scenarios; no lasers, annihilators or Bruce Willis drilling a huge peace of rock rushing towards Earth.

The system will consist of a network of robotic telescopes monitoring space around our planet, some of them delivered to orbit, others operating from the surface.

Destruction of an asteroid in emergency cases may be performed by a rocket with a powerful megaton-class thermonuclear warhead. If the threat is detected early, more advanced means of changing an asteroid’s orbit may be considered.

The program costing 58 billion rubles (over $1.9 billion) has already been handed over to the head of Russia’s defense industry, Deputy PM Dmitry Rogozin who is expected to present it to Prime Minister Dmitry Medvedev.

Lidia Rykhlova from the Institute of Astronomy (RAS) who presented the project, reported that Russia will need to modernize and fully computerize the 60 cm lens telescopes it already has. Several larger telescopes with 2 meter lens will have to be additionally installed.

Rykhlova announced that an analytical center will be created to collect the data from various sources and analyze it in real time mode.

However, Deputy Prime Minister Dmitry Rogozin has denied reports about the Russian government’s intentions to spend 58 billion rubles on asteroid defense system.

Professor of the Moscow State University, head of the laboratory for space monitoring Vladimir Lipunov told Interfax news agency that it will take about two years to modernize all Russia’s existing nine telescopes with the diameter of the lens of 40 centimeters and unite them into one network. A network of larger telescopes across the globe could be ready in five years.

“It will cost a mere trifle. What [Russian billionaire] Roman Abramovich paid for Chelsea [football club] would cover all the costs of the project,” Lipunov said.

According to Forbes during the eight years of owning Chelsea Abramovich spent $1.3 billion on the football club.

Lipunov stressed that tracking and forecasting space threats is more real and efficient than engaging air defense systems to deal with meteorites in the atmosphere, as people could be evacuated from an impact zone in advance.
Asteroid threat is growing by the year

“There are a lot of asteroids orbitingclose to Earth and every year up to 1,000 more are being discovered,” Lidia Rykhlova said, specifying that three years ago the number of known asteroids passing close to our planet was about 7,000 and now their number has grown up to around 9,400.

Most of the relatively large asteroids, with a diameter of one kilometer and larger are already known.

“We know about 90 per cent of kilometer-class asteroids, their orbits are well known and predictable. As for the smaller 40-50 meter ones – we still have insufficient observation apparatus. The more we observe – the more of them we find,” Rykhlova acknowledged.

If the space object is discovered beforehand, at least a month prior to possible collision with Earth, there is time to find out its size and consider various measures of its elimination.

The execution of a really complicated operation will require at least a year, Rykhlova pointed out.

“Therefore our emergency aid is a rocket with a nuclear warhead,” she concluded.
