The Planetary Data System is pleased to announce Release 14 of data collected by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) mission, including raw and calibrated products created from data acquired through the end of Mercury orbital operations on 30 April 2015.

MESSENGER’s instruments are the Mercury Dual Imaging System (MDIS), with wide-angle and narrow-angle cameras for imaging Mercury’s surface; a Gamma-Ray and Neutron Spectrometer (GRNS) and an X-Ray Spectrometer (XRS) for remote geochemical mapping; a Magnetometer (MAG) to measure the planetary magnetic field; a Mercury Laser Altimeter (MLA) to measure surface topography and planetary shape; the Mercury Atmospheric and Surface Composition Spectrometer (MASCS), combining an Ultraviolet and Visible Spectrometer (UVVS) with a Visible and Infrared Spectrograph (VIRS) to make high-resolution spectral measurements of the surface and to survey the structure and composition of Mercury’s tenuous neutral exosphere; and an Energetic Particle and Plasma Spectrometer (EPPS) to characterize the charged particle and plasma environment of Mercury.

The final release of calibrated and advanced products is 6 May 2016.
