In one of the first images transmitted back to Earth following
MESSENGER’s second flyby of Mercury, an image of the entire
departing planet (PIA11245), a spectacular and extensive
system of rays can be seen. This NAC image shows a close-up
view of the apparent source of those rays, a crater 110 kilometers
(68 miles) in diameter located in the northern region of Mercury.
The location of this bright crater is consistent with Earth-based
radar images, which suggested a very fresh, rayed impact crater
in this area. The amazing extent of this large ray system is visible
for the first time in MESSENGER’s newly acquired images.
Date Acquired: October 6, 2008
Image Mission Elapsed Time (MET): 131774306
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Resolution: 570 meters/pixel (0.35 miles/pixel) at the bottom left of the image
Scale: The extensively rayed crater is about 110 kilometers in diameter (68 miles)
Spacecraft Altitude: 22,000 kilometers (14,000 miles)
These images are from MESSENGER, a NASA Discovery mission to conduct the
first orbital study of the innermost planet, Mercury. For information
regarding the use of images, see the MESSENGER image use policy.
