New Frontiers in Science is an online journal that examines unexplained and controversial scientific phenomena. NFS publishes research and theories outside currently accepted scientific paradigms. The first issue of NFS focused on the new Mars Global Surveyor images of the Face on Mars. In this issue we present two papers involving the analysis of THEMIS imagery acquired over Cydonia by the Mars Odyssey spacecraft. Access to articles in previous issues is provided through the NFS Archive .

Vol. 1, No. 3 (Spring 2002): Analysis of THEMIS imagery over Cydonia


Analysis of Mars Odyssey THEMIS Imagery of the "D&M Pyramid"

Mark J. Carlotto

Themis image of D&M Pyramid on Mars 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.

Ancient Shoreline in Cydonia

Mark Carlotto

THEMIS MSI in Cydonia An analysis of a recent THEMIS multispectral image acquired by the Mars Odyssey spacecraft over Cydonia provides further evidence that an ocean once existed to the north, and that the features known as the City and Face are located along what was once its shoreline. It is shown that there are three spectrally distinct regions that are spatially correlated with MOLA-derived elevation data. One region is correlated with the higher terrain to the south, another with the low-lying plains to the north, and a third with a transition zone between the two. From its topography, relationships to the terrain to the north and south, spectral characteristics, and morphology of its features, it is conjectured that this transition zone was once the shoreline. The City, Face, and D&M Pyramid all lie in this zone. As either shoreline features, or even possibly islands, their proximity to water provides a possible explanation for how these once-symmetrical structures could have been transformed into their present, collapsed and highly eroded, state.
