Image Mission Elapsed Time (MET):
Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
18 kilometers/pixel (11 miles/pixel)
Mercury's diameter is 4880 kilometers (3030 miles)

Sub-spacecraft Latitude and Longitude:
The fifth set of optical navigation images (one of which is shown here) look as planned as the MESSENGER spacecraft closes in on Mercury. The time of its closest distance to the planet is October 6, 2008, 04:40:22 am EDT. This image appears similar to the previous optical navigation images taken earlier
but with the crescent-shaped Mercury growing larger and larger with each additional image set. Three more sets of optical navigation images are planned.
