Plasma waves
KiNET-X created Alfvén waves, disturbances in magnetized plasma, by releasing barium into the ionosphere, simulating natural auroral processes.
Electron energy
Barium plasma clouds transferred energy to ambient plasma, accelerating electrons along Earth’s magnetic field lines, mimicking auroral beams.
Golden data
A beam of energized electrons, called the “golden data point,” offered a rare glimpse into the processes behind auroras, as detailed by UAF scientist Peter Delamere.
