WebbPlain Language Summary The north polar cap of Mars consists of thick sheets of extremely pure ice called the north polar layered deposits and the sand‐rich basal unit. Radar data have been able to provide information on the composition of the north polar layered deposits; however, the composition of the basal unit is not entirely clear.
