Of Interest: The terminator returns! This color image portrays the striking separation of night and day on Mercury, evident in the change from dark to light. On Mercury, a solar day (the time it takes for the Sun to return to the same spot in the sky) is equal to 176 Earth days! Check out this animation of a day on Mercury!

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. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
