Planetary Data System Releases Final Raw MESSENGER Dataset
Laurel MD (SPX) Oct 12, 2015
Data collected during MESSENGER's 43rd through 49th months in orbit around Mercury were released to the public by NASA's Planetary Data System (PDS), the network of nodes that archives and distributes data from NASA's planetary missions. With this release, all data acquired by the MESSENGER mission are now available online - data collected through eight full Mercury solar days of orbit about the innermost planet in our solar system. NASA requires that all of its planetary missions archive th ... read more
