Diagrams Comparing Mars Features with Earth

Photo Captions Click on the icons below for diagrams that compare features on Mars with Earth. The first four of these were prepared by Stephen P. Meszaros, a resident of Phoenix, Arizona, in 1983/84. All five of these diagrams are available from the National Space Data Center, Greenbelt, Maryland.

1. Olympus Mons is about four times the height of Mt. Everest and would completely cover the state of Arizona. NASA photo 83-H-246.
2. The three Tharsis Montes volcanoes (North to South: Ascraeus Mons, Pavonis Mons, Arsia Mons) would form a range that spans the west coast of the United States. NASA photo 84-H-599.
3. The entire Tharsis volcano region. Olympus Mons in Northwest corner. Three Tharsis Montes at the center, compared with United States. NASA photo 84-H-597.
4. Valles Marineris is a giant rift system that would stretch across the United States. It is about four miles deep at its deepest point. NASA photo 84-H-595.
