MESSENGER

The MESSENGER (Mercury Surface, Space Environment, Geochemistry and Ranging) mission was launched in August 2004 on a long journey to Mercury. The spacecraft completed one flyby of Earth, two of Venus, and three of Mercury before entering Mercury's orbit in March 2011. MESSENGER is now in its second extended mission, which continues operations through March 2015.

Sept. 29, 2014. New SHADR and SHBDR products in the Radio Science RDR data set have been released. See ERRATA.TXT for details.

Sept. 5, 2014. MESSENGER Release 12

MESSENGER Release 12 includes raw and calibrated data acquired from Sept. 18, 2013, through March 17, 2014. With this release, data are now available for the sixth full Mercury solar day of MESSENGER orbital operations.
