| Has Mars always been a cold, dead world? What would Mars have been like
if there were rivers or oceans on its surface? Mars has a fairly active
climate and features that are continually changing. Mars has seasons, polar
caps, clouds, sand dunes, and dust devils, but no running water. This may
not have been the case in the past, however. Orbiting spacecraft (e.g.,
both Viking orbiters and the Mars Global Surveyor) have taken images
of the Martian surface showing features that may have been produced by running
water, such as channels, valleys, and canyons. Learn more about the Martian
climate, past and present! |
