Martian Morning Clouds Seen by Viking Orbiter 1 in 1976
No NASA Mars orbiter has been in a position to observe morning daylight on Mars since the twin Viking orbiters of the 1970s. This image, taken by Viking Orbiter 1 on Aug. 17, 1976, shows water-ice clouds in the Valles Marineris area of equatorial Mars.
NASA's Curiosity rover landed in the Martian crater known as Gale Crater, which is approximately the size of Connecticut and Rhode Island combined. A green dot shows where the rover landed, well within its targeted landing ellipse, outlined in blue.
This artist's impression Mars' Gale Crater depicts a cross section through the mountain in the middle of the crater, from a viewpoint looking toward the southeast. NASA's rover Curiosity will land in Gale Crater in August 2012.
This view of Lyot Crater is a combined mapping by NASA's Project Viking with elevation information from Mars Global Surveyor showing at least one of the nine craters in the northern lowlands of Mars with exposures of hydrated minerals detected from orbit.
Color mosaic of Olympus Mons volcano on Mars from the Viking 1 Orbiter. The mosaic was created using images from orbit 735 taken 22 June 1978. Olympus Mons is about 600 km in diameter and the summit caldera is 24 km above the surrounding plains.
