Caption:
18 October 2004
The best time of year to obtain images of the floor of the vast Hellas Planitia impact basin occurs in mid to late southern autumn. At that time of year, the atmosphere over this deep basin is clear and the solar illumination conditions are ideal. Hellas was in this ideal period during July-September 2004. This August 2004 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the eroded floor of a portion of the basin. Hellas has some of the lowest elevations on the planet. This image is located near 39.3°S, 302.8°W. The image covers an area about 3 km (1.9 mi) wide and sunlight illuminates the scene from the upper left.
