Chinese spy balloons aren’t the only strange thing flying over U.S. airspace as of late.
Numerous green laser lights were spotted over Hawaii on Jan. 28, initially believed to be from a NASA satellite that monitors the thickness of ice sheets on earth. However, the claim was retracted on Feb. 6, and responsibility was instead attributed to a Chinese atmospheric monitoring satellite.
The National Astronomical Observatory of Japan published a photo of the lasers on Jan. 28 saying they were “thought to be from a remote-sensing altimeter satellite ICESAT-2/43613,” the NASA satellite. Then, on Feb. 6, NAOJ released an updated report and said it was unlikely to have come from the NASA satellite due to the trajectory of the lasers.
NASA scientist Dr. Alvaro Ivanoff determined via a simulation that the culprit was likely China’s Daqi-1/AEMS satellite, according to Science Alert.
Daqi-1 monitors the earth’s atmospheric environment and can project lasers from its Aerosol and Carbon Dioxide Detection Lidar (ACDL), according to The Science Times.
NASA’s IceSAT-2 functions similarly and fired 10,000 lasers per second to measure changes on the earth’s surface, according to The Science Times.
