THE VERGE: The first sunlight reflecting space mirror has been cleared for launch

[Sev Clarke]

Colleagues,

This is somewhat concerning, particularly if the flat mirror could readily be turned into a concave one where sunlight could be focussed on say just a single square metre of the Earth’s surface, giving it the intensity of some 324 times that of ordinary sunlight. Alternatively, it might be turned into a fresnel lens with potentially similar dire effects. Focussed for just a few seconds on any soft target might well be enough to destroy it, before the focus and direction is changed to seek another one - say destroying ten targets every minute.

I particularly dislike SRM methods that have military usage.

Reflect Orbital has been given the green light to launch its first space mirror that aims to redirect sunlight down to Earth at night.
