|Syrtis Major and Arabia Terra
The Mars Global Surveyor Mars Orbiter Camera (MOC) has, in fact,
three cameras. The narrow angle system obtains monochrome
(black-and-white) super-high resolution views of the red planet, while
the wide angle system obtains regional and global views in both the
red and blue portions of the visible spectrum (to make a color image,
the red and blue are averaged to obtain the green channel). The picture
shown here is a composite of 9 color strips taken by the MOC on 9
successive orbits from pole-to-pole over the planet during the calibration
phase of the mission in March 1999. The large, circular bright region
that dominates the scene is Arabia Terra. Syrtis Major is the dark region
toward the lower right. The north polar cap is visible at the top, and the
bright feature at the lower right is the Hellas Basin. The color in this
picture is computer-enhanced and is not shown as it would actually
appear to the human eye.
Malin Space Science Systems and the California Institute of
Technology built the MOC using spare hardware from the Mars Observer
mission. MSSS operates the camera from its facilities in San Diego, CA.
