explanation
An icy mist and late afternoon clouds cover [ http://antwrp.gsfc.nasa.gov/apod/ap971013.html ] much of this section of Valles Marineris [ http://antwrp.gsfc.nasa.gov/apod/ap950720.html ] on Mars [ http://www.seds.org/~spider/mars/mars.html ]. The Valles Marineris or Mariner [ http://bang.lanl.gov/solarsys/marin9.htm ] Valley is a huge canyon system about 2,000 miles long [ http://www.hawastsoc.org/solar/cap/mars/vidmars2.htm ] and up to 5 miles deep. This test image [ http://www.msss.com/mars/global_surveyor/ camera/images/p13_color_release/index.html ] was produced using data from Mars Global Surveyor [ http://mpfwww.jpl.nasa.gov/mgs/index.html ]'s wide angle cameras viewing the canyon from a distance of 360-600 miles. Color was synthesized using images recorded through blue and red filters. Mission controllers [ http://mpfwww.jpl.nasa.gov/mgs/status/status.html ] have recently raised the spacecraft's aerobraking [ http://antwrp.gsfc.nasa.gov/apod/ap970911.html ] orbit to study the unexpected motion of one of the Surveyor's solar panels [ ftp://ftp.hq.nasa.gov/pub/pao/pressrel/1997/97-232.txt ].
