PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

Original Caption Released with Image:

About 91 minutes after MESSENGER’s closest pass by the planet, MDIS acquired this image of Mercury’s northern surface, which is one in a set of 48 that form a mosaic of the departing planet. In this image, the left portion of the surface fades into darkness at the terminator, the line between the sunlit dayside of the planet and the dark night side. The left-side portions of the surface that are just coming out of the darkness are being hit with the first rays of morning sunlight. Some of the surface to the right of this scene can be viewed in this previously released image looking toward Mercury’s north pole (PIA10193).

Date Acquired: January 14, 2008
Image Mission Elapsed Time (MET): 108830334
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Resolution: 0.8 kilometers/pixel (0.5 miles/pixel)Scale: The width of this image is about 800 kilometers (500 miles)
Spacecraft Altitude: 30,700 kilometers (19,100 miles)

These images are from MESSENGER, a NASA Discovery mission to conduct the first orbital study of the innermost planet, Mercury. For information regarding the use of images, see the MESSENGER image use policy.
