THEMIS: North polar layers and sand dunes
THEMIS Image of the Day, July 23, 2019. Today’s VIS image shows part of the north polar cap, as well as sand dunes located on the floor of a polar trough.
The north polar cap is surrounded by numerous dune fields — nicknamed the north polar sand sea — as well as dunes within many of the troughs near the polar cap margin. This image was collected during northern summer.
