Hi,
I read something interesting about some amateur astronomers lasing the ISS with a blue-light laser, and the astronauts were able to spot it.
How powerful would a laser have to be to be seen by the human eye from Mars? It would be shone from the dark side of Earth of course. Are we talking one (or several) guide star lasers from the big observatories? Metal-cutting beams (c. 50w)? Naval anti-missile experimental lasers (c. 100 kw)?
Any input appreciated.
Thanks
