Mars Global Surveyor's Mars Orbiter Camera is providing geologists with vistas that rival that of the aerial photographs they use in their field work on Earth. This picture shows the margin of a large lava flow located on Daedalia Planum, southwest of the Arsia Mons volcano.
Illumination is from the upper left.
Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission.
