So heard today on public radio that NASA may be using laser antennas to send and receive information to astronauts in space. According to the report, laser Antenna are faster, more accurate, carry more data, more reliable, etc.Questions:+ Currently possible?+ possible UAV application?+ Expensive?

I think there is more merit to this than meets the eye. We are already making very good quality gimbals. These can be used to mount the optics. The only limitation I see is that the laser has to be over 5mW to get range over 200m or so. Plenty of hobbyists are using fixed laser data links for LOS house to house data transfer.
