Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
500 meters/pixel (0.31 miles/pixel)
The diameter of Firdousi is 96 kilometers (60 miles)
This image is a portion of the global Mercury
The crater in the center of the image was named Firdousi in March 2010
in honor of HakÄ«m Abu'l-QÄsim FirdawsÄ« TÅ«sÄ« (940-1020), a revered Persian poet and author of the ShÄhnÄmeh, the national epic of the Persian people. MESSENGER imaged this crater at an oblique angle
as the spacecraft approached Mercury for its third flyby. The view shown here is a cylindrical reprojection
. Firdousi is notable for the distinctive chains of small secondary craters
that radiate outward from the main impact site. That these chains of secondary craters can still be seen and have not been obliterated by subsequent impact events indicates that Firdousi is a relatively young crater on Mercury's surface.
