Odyssey Over Mars
Credit: THEMIS, Mars Odyssey Team, JPL, NASA
Scroll right and journey for 300 kilometers over Terra Sirenum
in the cratered highlands of southern Mars. The infrared view,
32 kilometers wide, was recently recorded by the THEMIS
camera on board the orbiting Mars Odyssey spacecraft.
Beginning at the north (left) edge, the scene sweeps across
the floor and over the rim of Koval'sky Crater. Continuing
southward (right) of the crater's rim are lava flows exhibiting
fractures and numerous smaller impact craters. The infrared
image was made in daylight hours, so sun-facing slopes are
still warm and bright while shadowed areas are cool and dark.
But rocky regions also tend to remain cooler and darker than
their surroundings, likely corresponding to the dark blotchy
terrain along the Koval'sky Crater floor and dark rings of rocky
ejecta surrounding some of the smaller craters.
