“…Satellite-illuminator must have a reflector in the form of a bowl — the concave mirror…

If the satellite illuminator to make of elastic material, it is possible to bring it to orbit and there to inflate. The surface, which will serve as a mirror, it is necessary to cover with a layer of metal. You can make several of these reflectors of small size, collected in one place. If one of them collapses, faced with a meteor, the entire complex will be destroyed.

I think the day when people around the world forget the words “Eastern camp and Western camp” and all together give your hand to study space and other peace issues”…”
