Tropical to mid-latitude snow and ice accumulation, flow and glaciation on Mars
Article Abstract:
The results from the High Resolution Stereo Camera (HRSC) on board Mars Express that show evidence for the presence of significant volumes of ice and glacial-like flow in massif-marginal deposits at low to mid-latitudes and very young glacier deposits in equatorial regions are presented. The data indicate that abundant residual ice on Mars probably remains in these deposits and that these records of geologically recent climate changes are accessible to future automated and human surface exploration.

Discovery of a flank caldera and very young glacial activity at Hecates Tholus, Mars
Article Abstract:
A new image and topographic data from the High Resolution Stereo Camera that disclose unknown traces of an explosive eruption at 30 degree north (N) and 149 degree east (E) on the northwestern flank of the shield volcano Hecates Tholus, Mars, are presented. The discovery of very young glacial features indicates recent climate changes and also the absolute ages of these very recent glacial deposits correspond very well to a period of increased obliquity of the planet's rotational axis.

Recent and episodic volcanic and glacial activity on Mars revealed by the High Resolution Stereo Camera
Article Abstract:
The large-area coverage at a resolution of 10-20 meters per pixel in color and three dimensions with the High Resolution Stereo Camera Experiment on the European Space Agency Mars Express Mission has made it possible to study the time-stratigraphic relationships of volcanic and glacial structures in unprecedented detail and give insight into the geological evolution of Mars.
