EXCERPTS: . . . Thankfully, this wasn't some alien spaceship scanning Earth for signs of life. It appears the mysterious green beams actually came from an orbiting satellite. But not the one we expected.
Originally, experts at the National Astronomical Observatory of Japan (NAOJ), which co-owns the camera, announced on Twitter that the green light probably came from a radar device on an orbiting satellite, known as ICESat-2.
ICESat-2 is owned by NASA, and it's used to keep an eye on the thickness of Earth's sea ice, ice sheets, and forests. But on 6 February 2022, NAOJ updated their footage of the laser beam saying that based on the trajectory, it was unlikely to be NASA after all.
[...] "China will produce a series of Daqi satellites in the future, which will be used to monitor atmospheric pollution, provide remote sensing data support for environment authorities, and also support scientific research into global climate change," the March 2021 press release explained.
"Daqi-1 will be networked with other satellites, including Daqi-2, to realize greenhouse gas monitoring and help China achieve reduction of carbon emissions."
It's yet to be seen whether these green atmospheric detecting lasers may become more common as China achieves this goal... (MORE - missing details)
