<p><b class="first">T</b>he fourth planet from the Sun (227,940,000 km), Mars is
|
|
our solar systems Red Planet.</p>
|
|
|
|
<p>With recent explorations to the planet by the Mars Global Surveyor and the
|
|
Mars Pathfinder missions, a portal has been opened to a planet that could
|
|
possibly sustain primitive live Martians.</p>
|
|
|
|
<p>Temperatures on the Martian surface range widely from -135 degrees C to 27
|
|
degrees C during winter at the ice capped poles. The poles, containing bright
|
|
crystallized ice are composed of solid carbon dioxide or dry ice. Since,
|
|
missions to Mars have begun to transform into a scientific reality, the Martian
|
|
landscape had to be thoroughly examined for possible landing sites. Although a
|
|
possible ancient living ground, the Martian surface still holds expanses of
|
|
plains, ridges, and rift valleys.</p>

<p>Mars has a very thin atmosphere composed of carbon dioxide (95.3%), nitrogen
|
|
(2.7%), argon (1.6%) with traces of oxygen (0.15%) and water (0.03%).</p>
|
|
|
|
<p>The pressure on the surface is only one percent of that of <a href="earth.htm">Earth's</a>, but the
|
|
pressure varies greatly throughout the Martian landscape.</p>
|
|
Mars is closely orbited by two tiny satellites: Phobos and Deimos.
