PIA06108: Northern Plains Scene

Northern Plains Scene


30 January 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a typical view of the martian northern plains during northern summer. In spring and summer, dust devils crisscross the plains, creating dark, filamentary streaks such as those shown here. MOC has rarely observed actual active dust devils on the northern plains, suggesting that these probably occur at a time of day that is different than the ~2 p.m. local time when MGS flies over these surfaces. As with high latitudes on Earth, daytime lasts longer in summer than at lower latitudes; thus, dust devils might occur earlier or later in the afternoon than is common in equatorial settings.
