Summer at the Martian South Pole

Images released by NASA JPL show the southern polar cap of Mars at it appeared on 17 April 2000. According to JPL; “In winter and early spring, this entire scene would be covered by frost. In summer, the cap shrinks to its minimum size, as shown here. Soon the cap will experience sunsets; by June 2000, this pole will be in autumn, and the area covered by frost will begin to grow. Winter will return to the south polar region in December 2000.”
