Lasers fired at the earth?

In one of the previous publications we talked about some spirals of light captured by a Webcam in an astronomical observatory in Hawaii, and they are not special effects, in the publication Strange phenomena in the sky the publication Strange phenomena in the sky. the phenomenon is explained.

And a couple of weeks later, on January 28, that same camera at the National Observatory of Japan at the top of the MaunaKea volcano in Hawaii, captures a succession of vertical green lines that appear from one side of the image to the other.

But before anyone speculated about it, the Twitter account te lo observatorio clarified that it was a NASA ICESAT-2 satellite that with its Atlas topographic instrument emits light pulses with a laser to make measurements of the Earth's surface, It's just that it's that satellite, that night, at that precise moment, it was in another part of the world, not over Hawaii.

They realized this almost a week later and published the clarification saying that scientists working on NASA's ICESAT-2 simulated the trajectories of satellites that have instruments similar to Atlas and came to the conclusion that the Green laser captured in the video comes from a Chinese satellite.

The trending topic right now is Chinese balloons shot down by US military planes over US and Canadian territory, so as you can imagine the tensions are rising, the news is just coming out because now we know it was a Chinese satellite and not from The NASA.

The precedents are on the table, with a few "crashed" balloons, flying over several countries and continents, this Chinese satellite is shooting green lasers over Hawaii.

Although it looks like a science fiction weapon in reality the satellite that shoots lasers, apparently it is not a threat, in fact, it is the Daqi-1 satellite, it is an atmospheric monitoring satellite of air quality manufactured in the shanghai academy of space technologies and its mission is to make measurements of atmospheric gases and pollutants.

Souce

It is the first satellite equipped with lighter technology, which is what cars with autopilot use to avoid crashing into other cars or pedestrians or bicycles or puppies, but in this case the satellite uses it to detect levels of carbon dioxide and aerosols in the atmosphere, this is done by means of a laser that shoots short pulses of light on the Earth's surface and when that light bounces off the molecules it finds in the air when it reflects back to the satellite, its sensors can know which molecules are in the air and in what concentrations, such as carbon dioxide, water vapor, smoke from burning fossil fuels and other particles, suspended pollutants.
