ESA's Optical Ground Station took this extraordinary video of the International Space Station on October 8 as it was being illuminated by a 3.6-Watt 532-nm green laser. The video was taken at 7 frames per second, but the final effects is amazing. It's incredible to see it moving like that.
This extraordinary video clip was recorded at ESA's Optical Ground Station (OGS) at about 19:05 UTC on 8 October 2014 as the station illuminated the ISS with a 3.6-Watt 532-nm green laser, used for testing next-gen optical communication technologies. The video clearly shows the ISS bathed in green light as it is tracked by the OGS through the 4-minute pass at an altitude of about 420 km.
