Research shows: The Falcon 9 rocket disintegration caused the concentration of lithium atoms in the high-altitude atmosphere to increase tenfold.

German researchers published a research report in the British journal "Communications Earth & Environment" on the 19th, saying that one year ago on this day, during the disintegration of a part of the body of a SpaceX Falcon 9 rocket in the atmosphere, the concentration of lithium atoms in the upper atmosphere surged tenfold. This is the first time scientists have directly measured environmental pollution caused by space debris entering the atmosphere. With the rapid development of space exploration technology and the increasing amount of space debris, these findings are of great significance.
