My favorite "lasers at distance" thing will be when amateurs can get a few photons back from the mirrors left on the moon https://en.wikipedia.org/wiki/Lunar_L

Not quite there yet at the amateur level, private industry soon, but then there is the question of safety to air traffic.
Can you imagine the first moon data link? JWST has 8mbps
- eesmith 1y agoPeople do use radio (though not optical) for Earth-Moon-Earth data links: https://en.wikipedia.org/wiki/Earth%E2%80%93Moon%E2%80%93Earth_communication https://en.wikipedia.org/wiki/Earth%E2%80%93Moon%E2%80%93Ear...

- Calwestjobs 1y agothey will heat starlink first.
- vmh1928 1y agoModulating a laser beam for communications is not new but this distance effort by amateurs doing a two-way voice transmission over 167km in New Zeland is pretty cool. This article also mentions a number of other laser communication long distance efforts. https://www.modulatedlight.org/Modulated_Light_DX/MODULATED_LIGHT_DX.html https://www.modulatedlight.org/Modulated_Light_DX/MODULATED_...
