May 12, 2017. MESSENGER Release 16 includes revised MLA altimeter profiles (RDRs) and a northern-hemisphere DEM (GDR). It also includes a set of SPICE SPK kernels supporting the navigation ephemeris correction measurements performed by the MLA team during the final months of the mission. See the ERRATA.TXT file in the top-level directory for details.

The revised RDR and GDR products in this release are provided on a new archive volume, MESSMLA_2101. This volume contains only RDR and GDR products, plus the SPK kernels; no CDRs or RADRs. The revisions are due to calibration and data processing improvements; however, the previous versions of these products will remain available on volume MESSMLA_2001. See below for links to both volumes.

MLA is the Mercury Laser Altimeter instrument on MESSENGER. The data sets are produced by the MLA Science Team at the NASA / Goddard Space Flight Center, Greenbelt, Maryland.
