In April 2002 the Thermal Emission Imaging System (THEMIS) aboard the Mars Odyssey spacecraft acquired a 19 meter/pixel visible image over a region in Cydonia containing the Face, D&M Pyramid, and the eastern portion of the City. This new image provides the first fully illuminated view of the D&M Pyramid a faceted landform south of the Face first imaged by Viking in 1976. The new THEMIS image shows the D&M Pyramid is a highly symmetrical object with striking similarities to other objects in Cydonia. The presence of two highly symmetrical objects the Face and the D&M Pyramid with completely different morphologies, less than 20 km apart, suggests the possibility that this collection of objects could be the eroded remains of ancient artificial structures on the Martian surface.
