Opportunity caught this view of Martian clouds over Endurance Crater at 9:30 a.m. (Mars time) on Nov. 16, 2004, its 290th mission day. Similar to cirrus clouds on Earth, these clouds are part of a band that forms near the equator when Mars is near the part of its orbit that is farthest from the Sun. Credit: NASA/JPL.
