This Mars Orbiter Camera (MOC) picture shows the Elysium region of Mars as it appeared from the Mars Global Surveyor (MGS) spacecraft on on August 20, 1997. At the time, MGS was 5.57 million kilometers (3.46 million miles) and 22 days from Mars, and the picture has a resolution is about 20.8 km per picture element. Mars, 6800 km (4200 mile) in diameter, is about 327 pixels across. North is at the top of the image. The camera was pointed at the center of the planet (near the dark, morning sunrise line, or terminator) at 23.6° N, 217.4° W. At this distance from Mars, only atmospheric phenomena (clouds and fogs) and bright and dark markings resulting from variations in the amount and thickness of dust and sand are usually visible. However, in this view the shading of the relief of the three Elysium volcanoes (from north to south Hector Tholus, Elysium Mons, and Albor Tholus) can be seen owing to their position close to the terminator. Elysium Mons, the center-most volcano, is estimated to be 12,000-14,000 meters (39,000 to 46,000 feet) high.

Note: This MOC image is made available in order to share with the public the excitement of new discoveries being made via the Mars Global Surveyor spacecraft. The image may be reproduced only if the image is credited to "Malin Space Science Systems/NASA". Release of this image does not constitute a release of scientific data. The image and its caption should not be referenced in the scientific literature. Full data releases to the scientific community are scheduled by the Mars Global Surveyor Project and NASA Planetary Data System. Typically, data will be released after a 6 month calibration and validation period.
