Research shows: The disintegration of the "Falcon 9" rocket caused a tenfold increase in the concentration of lithium atoms in the upper atmosphere

German researchers published a research report on the 19th in the UK journal "Communications - Earth and Environment," stating that on the same day a year ago, a part of the Falcon 9 rocket from SpaceX disintegrated upon re-entering the atmosphere, causing the concentration of lithium atoms in the upper atmosphere to surge tenfold. This is the first time scientists have measured environmental pollution caused by space debris falling into the atmosphere. In the context of rapid advancements in space exploration technology and the increasing amount of space debris, this finding is of significant importance. (Xinhua News Agency)
