Mars - Viking 1 Orbiter

Global mosaic of Hellas and Arabia areas on Mars

Mars
Global mosaic of Viking 1 Orbiter images giving an orthographic projection showing the Hellas Planitia (at lower left of the frame) and Arabia (upper right) regions of Mars. The mosaic covers the area from -70 to 50 degrees latitude and 260 to 360 degrees longitude. The images were acquired on 7 July 1980 on orbit 1483 during late northern summer on Mars. The bright area at the bottom of the image is Hellas Planitia, a large deep basin about 2000 km in diameter. The bright white coloring is due to carbon dioxide frost in the bottom of the basin, parts of which are about 8 km lower than the mean planetary surface. The large bright region at the top is Arabia. Thin white clouds can be seen over the northern (upper) portions of the image. (Viking 1 Orbiter, MF31S343-483SO)
