Of Interest: Today's image features the crater Berlioz, a newly named crater within Mercury's northern plains. Berlioz is the larger crater in this image, with the central peak complex that ironically looks a bit like a smiling face. Hector Berlioz (1803-1869) was a French Romantic composer who was heavily inspired by Shakespeare and Goethe, in particular their works which involved tragedy. Among his most famous works is 'Symphonie fantastique', about a young musician's unrequited love.
This image was acquired as part of MDIS's 8-color base map. The 8-color base map is composed of WAC images taken through eight different narrow-band color filters and covers more than 99% of Mercury's surface with an average resolution of 1 kilometer/pixel. The highest-quality color images are obtained for Mercury's surface when both the spacecraft and the Sun are overhead, so these images typically are taken with viewing conditions of low incidence and emission angles.
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.
