Explanation:
The Mars Global Surveyor spacecraft has
returned another close-up
of the Cydonia region on Mars.
Orbiting over clear Martian skies
at a range of about 200 miles,
the Mars Orbiter Camera
looked down on features known as
the "City" on Mars and produced
a high resolution image covering a swath around 1.5 by 15 miles
at a pixel size of about 8.2 feet.
This cropped portion of
the processed image shows an area approximately
1.5 miles wide.
Heavily weathered hills and pocked surfaces suggest the erosion
of layers of the ancient
Martian crust.
