Xiao Zhao's Rays Paint Mercury's Surface
Release Date: May 19, 2008
Topics: Crater Rays, Mercury Flyby 1, NAC, Named Craters, Xiao Zhao

Date Acquired: January 14, 2008
Image Mission Elapsed Time (MET): 108828473
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Resolution: 500 meters/pixel (0.3 miles/pixel)
Scale: Xiao Zhao crater is 23 kilometers (14 miles) in diameter
Spacecraft Altitude: 19,760 kilometers (12,280 miles)

Of Interest: Recently named after the 12th century Chinese artist, Xiao Zhao crater on the central left side of this image is small in comparison with many other craters on Mercury and even with many other craters in this scene. However, Xiao Zhao's long bright rays make it a readily visible feature. The fresh, bright rays, which were created by material ejected outward during the impact event that formed the crater, indicate that Xiao Zhao is a relatively young crater on Mercury's surface.
