Planet Earth Space Fence

Since the beginning of planet Earth, strange things have been falling from space

And in present time things still fall on Earth. Or are seen crossing the sky. Like fireballs, meteors, comets and even Unidentified Flying Objects. Also known as UFO's.

Both the Russians and Americans have been working on the construction of a space defense system since a few decades. And these systems need an upgrade from time to time.

As the world turns and the variety of space objects keep increasing, the need for good space fences and NEO - Near Earth Objects detectors, are increasing as well.

The new system is not an upgrade of the old system, but an entirely new, and costly way to conduct surveillance of the skies,
