This somewhat oblique blue wide angle
Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
image shows the 174 km (~108 mi) diameter crater, Terby,
and its vicinity in December 2004.
Located north of Hellas, this region can be covered with
seasonal frost and ground-hugging fog, even in
the afternoon, despite being north of 30°S.
The subtle, wavy pattern is a manifestation of fog.

Location near: 28°S, 286°W

Illumination from: upper left

Season: Southern Winter

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, California.
The Jet Propulsion Laboratory’s Mars Surveyor Operations Project
operates the Mars Global Surveyor spacecraft with its industrial
partner, Lockheed Martin Astronautics, from facilities in Pasadena,
California and Denver, Colorado.
