The three flashes of green light came from the space agency’s ICESat-2 satellite.
The video footage was captured on September 16, 2022. It shows three streaks of light zip across the sky against a backdrop of scattered clouds. Upon further scrutiny, Fujii realized the green streaks pulsed in time with a light that briefly appeared between the clouds .Guessing it was a satellite, Fujii checked out what spacecraft were flying above the cameras that night. Lo and behold, ICESat-2 appeared a likely culprit.
ICESat-2 fires 10,000 times per second, according to NASA. The satellite’s been imaged from the ground before, but not its laser pulses, which require unique atmospheric conditions to be spotted.The clouds over Hiratsuka City Museum that night scattered the laser light enough to make it visible to Fujii’s cameras, but there were not so many clouds to block out the light.
So the next time you see a bright light in the sky, it may not be a meteorite or aliens. It may just be human instruments, keeping track of goings-on on the ground.
