During MESSENGER’s second Mercury flyby, the first images that were taken following closest approach were acquired using the WAC’s 11 narrow-band color filters. Five different scenes were acquired in 11 filters each, resulting in 55 images total that comprise a 5 column x 1 row mosaic. The individual WAC image shown here is the fifth scene of that 5x1 mosaic. The large, smooth-floored crater near the center of the image is Titian, named in honor of Tiziano Vecellio, the Italian Renaissance painter. Scenes one, two, three, and four of this mosaic can be viewed in previously released images. Though the entire 5x1 mosaic only took about six minutes to be obtained, the resolution of the images changed by a factor of two between scene one and scene five shown here, as the MESSENGER spacecraft sped away from Mercury. An enhanced color movie using images from this mosaic has also been released (see PIA11416).
