Spring Comes To The Southern Highlands SpaceDaily

Over the past six months, the southern hemisphere of Mars has passed through spring and into summer. Spring started in early August 1999 and summer arrived toward the end of December 1999. Mars Global Sureyor (MGS) is in a polar orbit, thus the spacecraft’s Mars Orbiter Camera (MOC) has had an excellent view of the daily changes that have occurred as the south polar frosts sublimed away during spring and into the summer season.
