Russia has announced it is willing to start building asteroid protection systems. Federal Space Agency deputy head Viktor Remishevsky said that Russia is capable of using existing missile technology to build ant-asteroid systems if necessary, and that international co-operation was necessary to combat any potential threats. 

Quote: ""The Russian missile industry is capable of manufacturing anti-asteroid systems if necessary," he said. "So far, there are no techniques to use the existent space machinery for fighting asteroids."" The asteroid danger is not on the Federal Space Agency program. "If a method of suppressing this danger with space machinery is found, we will make such systems. Anyway, the missile industry can do that," he said. Asteroids are a problem to be tackled through international cooperation, Remishevsky said. �Research satellites, telescopes and land-based infrastructure of the Russian Academy of Sciences must supply information about the asteroid danger,� he said.

Scientists hope to have calculated the orbits of at least 90% of all asteroids with a diameter greater than 1 kilometre by the end of next year. In 2002, Nasa reported on several asteroids that passed between the earth and the moon, one even coming within 75,000 miles of the planet. But these asteroids were only detected days after they passed by earth. If there is an asteroid on a collision course with earth, and according to the Scriptures at least one will strike during the tribulation period, then there seems to be very little we can do about it.

Revelation 8:8-9
And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood; And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed.
