– RSS EDR – Raw radio science data and ancillary files from the GRAIL mission.

This release comprises data from both the primary and extended mission phases and includes version 4 of LGRS EDR and CDR data, along with revisions to some RSS EDR data. It is also the first release of RSS EDR data from all other mission phases.
