Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
7 (748 nanometers)
Mercury's radius is 2440 km (1516 mi.)
This stunning view includes both the terminator
and the limb
crater, an 80-km-diameter, complex crater with a prominent central peak, can be seen near the center of the scene.
The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation
are unraveling the history and evolution of the Solar System's innermost planet. Visit the Why Mercury?
section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
