NASA’s Curiosity Mars rover captured this beautiful view of nightfall on the Red Planet on April 15, 2015. The red surface coloring of Mars is due to oxidized iron. At certain times of the Martian year, great dust storms occur; the large amounts of dust in the atmosphere during these storms absorb much of the incoming radiation from the Sun; this causes large temperature inversions in the Martian atmosphere.
