the surface of Mars Center of the landing elhpse<br />

224° N Lat. 4Z5~ W L~mg inChr)sePlanitia The<br />
new location i~ about 740 kilometers (460 miles)<br />
northwest of the original <strong>July</strong> 4 landing site and<br />
240 kilometers (150 miles) west of an alternate site<br />
where the spacecraft was to touch dowt~ on Jul) 17<br />
This area ~ nearl) three kilometers (two miles)<br />
below Mars ’ mean "sea level "" It is a ehannelled lowland<br />
northeast of the great /¢Jartlan ~,olcanoes and<br />
the Tharsis Plateau the high altitude equatorial<br />
region.<br />
