- *Martian Moon: Phobos
Phobos ("FOH bus") is the larger and innermost of Mars' two moons. Phobos is closer to its primary than any other moon in the solar system, less than 6000 km above the surface of Mars. It is also one of the smallest moons in the solar system.

- Atmosphere and Interior of Mars
The atmosphere and the interior of Mars differ substantially from that of the Earth. The atmosphere is much less dense and of different composition, and it is unlikely that the core is molten.

- Face on Mars
In July, 1976, Viking Orbiter 1 was acquiring images of the Cydonia region of Mars as part of the search for potential landing sites for Viking Lander 2. On 25 July, 1976, it photographed a region of buttes and mesas along the escarpment that separates heavily cratered highlands to the south from low lying, relatively crater-free, lowland plains to the north.

- General Features of Mars
Mars has a rotational period of 24 hours and 37 minutes, a period for revolution about the sun of 687 days, and a diameter of 6800 km (about half that of Earth). This site has a rotating globe animation.

- Life on Mars?
A team of scientists recently announced that they believe they have found evidence for ancient microbacterial life in a chunk of meteorite that came from the planet Mars. The startling news would be the first discovery of any form of life off the Earth. It could revolutionize our thoughts on the probability of life arising elsewhere in our solar system and the universe beyond, especially in the light of recent news about planetlike bodies detected around other stars.

- Mars Exploration Homepage
Since our first close-up picture of Mars in 1965, spacecraft voyages to the Red Planet have revealed a world strangely familiar, yet different enough to challenge our perceptions of what makes a planet work. Every time we feel close to understanding Mars, new discoveries send us straight back to the drawing board to revise existing theories.

- Mars Meteorites
Of the 22,000 or so meteorites that have been discovered on Earth, only 26 have been identified as originating from the planet Mars. These rare meteorites created a stir throughout the world when NASA announced in August 1996 that evidence of microfossils may be present in one of these Mars meteorites.

- Mars Pathfinder
Mars Pathfinder was originally designed as a technology demonstration of a way to deliver an instrumented lander and a free-ranging robotic rover to the surface of the red planet. Pathfinder not only accomplished this goal but also returned an unprecedented amount of data and outlived its primary design life.

- Surface Features of Mars
Mars has many interesting geological features on its surface that first became apparent with Mariner 9, were subsequently studied by the Viking missions, and many of which now are visible from the Hubble Space Telescope. These surface features include polar caps, enormous shield volcanoes, large canyon systems and running water erosion.

- Viking Lander
In 1976 the Viking 1 and 2 landers undertook searches on the Martian surface for the chemical evidence of present or past life on Mars. The images shown give a picture of one of the backup landers, and two different views of the Martian surface as photographed from Viking 1.

- Water Ice on Mars
Using instruments on NASA's 2001 Mars Odyssey spacecraft, surprised scientists have found enormous quantities of buried treasure lying just under the surface of Mars -- enough water ice to fill Lake Michigan twice over. And that may be only the tip of the iceberg.
