This picture is a composite of Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) daily global images acquired at Ls 145° during a previous Mars year. This month, Mars looked similar, as Ls 145° occurred in mid-January 2005.

This picture shows the Elysium/Mare Cimmerium face of Mars. Over the course of the month, additional faces of Mars as it appears at this time of year were posted for MOC Picture of the Day.

Ls, solar longitude, is a measure of the time of year on Mars. Mars travels 360° around the Sun in 1 Mars year. The year begins at Ls 0°-- the start of northern spring and southern summer. In January 2005, it is northern summer and southern winter. The seasons on Mars occur according to Ls, described in the following table:

0° - 90°
northern spring, southern autumn
90° - 180°
northern summer, southern winter
180° - 270°
northern autumn, southern spring
270° - 360°
northern winter, southern summer
