Using Space as a Non-linear Plasma Laboratory

Active cause-and-effect experiments are an extremely leveraged way to develop scientific understanding of the behavior of space plasmas. The recent sophistication and innovative use of ionospheric heaters, along with the fact that we can repeat the experiments for varying space conditions makes them the mode of choice in using space as an open plasma and geophysics laboratory. Following a brief introduction to ionospheric heating results of recent experiments that utilized the ionospheric heater and diagnostic instrumentation of the High-Frequency Active Auroral Research Program (HAARP) located in Gakona, Alaska, in conjunction with satellite and remote site ground measurements will be presented.
