Late last week, the Planetary Data System (PDS) released data collected during MESSENGER's seventh through twelfth month in orbit around Mercury. PDS archives and distributes all of NASA's planetary mission data. With this release, images and measurements are now available to the public for the second full Mercury solar day of MESSENGER orbital operations. NASA requires that all of its planetary missions archive data in the PDS, an active archive that makes available well-documented,...

The Planet Mercury -- in astronomy, nearest planet to the sun, at a mean distance of 36 million mi (58 million km); its period of revolution is 88 days. Mercury passes through phases similar to those of the moon as it completes each revolution about the sun, although the visible disk varies in size with respect to its distance from the earth. Because its greatest elongation is 28, it is seen only for a short time after sunset or before sunrise. Since observation of Mercury is...
