Solspace orbital mirrors will increase energy production on earth

Serial launches of SpaceX’s reusable Falcon 9 rockets have reduced the cost of putting cargo into orbit to $1500 per 1 kg. When the larger Starship rocket starts flying, the price will drop by another third, and when these rockets can be used on a permanent basis, the price will drop to $232 per 1 kg. This is the threshold that makes various bold experiments in space cost-effective and the launches themselves affordable for small private entities.

The Solspace project from scientists at the University of Glasgow is focused on this price factor. They intend to build a full-fledged orbital constellation of sunlight reflectors to transmit it to Earth.
