Even though Mars has lost much of its overall magnetic field, some areas still create unique atmospheric electrodynamic structures – magnetic loops and cusps which alter how ions leave its atmosphere. Sabine Stanley and her colleagues have developed an effective technique for artificially creating these structures. Their paper published in Science details how this can
