Laser signals carry more data but the light is almost undetectable by the time it reaches Earth. Now a nanoscale light detector could make such deep-space missives easier to read.
Earth's atmosphere including clouds can also thwart laser signals. To maximise the chance of cloudless skies LLCD will be able to beam its light to any of three detectors in New mexico California or Spain.
laser signals could make it possible to build smaller, lower powered satellites that can still talk to the ground easily."
