The US government's High Frequency Active Auroral Research Program (HAARP)(1), a favorite subject of conspiracy theorists, uses a high frequency, high-power transmitter to temporarily excite a small part of the ionosphere. One theoretical use for HAARP is to produce an ion outflow that drags oxygen up to 800km and could be used to enhance the drag on orbiting satellites (and presumably debris as well), de-orbiting them faster.(2) 1) https://en.wikipedia.org/wiki/High_Frequency_Active_Auroral_Research_Program https://en.wikipedia.org/wiki/High_Frequency_Active_Auroral_... 2) https://www.nap.edu/read/18620/chapter/6 https://www.nap.edu/read/18620/chapter/6
