"Residents for hundreds of miles were taken by surprise by these strange lights, which prompted calls to the police and 'The aliens are coming!' hysteria!"
Its goal is to measure winds and currents in the ionosphere, a electrically-charged layer of the Earth's atmosphere where auroras appear. Specifically, the researchers are interested in discovering how auroral energy might percolate down toward Earth to influence the lower atmosphere.
The twin rockets deployed two chemical tracers: trimethyl aluminum (TMA) and a barium/strontium mixture. These mixtures create colorful clouds that allow researchers to visually track the flow of neutral and charged particles, respectively.
