As fotos foram feitas em cerca de 1500 observações dos telescópios da Mars Reconnaissance Orbiter, nave controlada pela NASA que orbita o planeta vermelho desde 2006.


Dunas, crateras, camadas geológicas e outras formações foram capturadas pela câmera do experimento High Resolution Imaging Science (HiRISE) que, à bordo da nave, registrou as imagens entre Abril e Agosto de 2009.
