This picture was taken by the NASA robot “Spirit” over the course of 5 months. The “McMurdo panorama” is a combination of more than 1400 individual pictures which were taken when the lack of sunlight didn’t allow the rover to move during the Marsian winter.
For improved immersion, the interactive panoramic image has been contrast enhanced and the sky is an extrapolation from the narrow band of sky in the original pictures (so there is no sun, for example.) Based on images courtesy of NASA/JPL/Cornell.
