A. 2020 Performance data for one MESSENGER maneuver migrated from original PDS3 archive to PDS4. 2020-10-15 1.0 These data have been migrated from PDS3 PRODUCT_ID MESS_RS_2014255_2014255_MPD in data set MESS-V/H-RSS-1-EDR-RAWDATA-V1.0 to PDS4. Formatting was adjusted so that each Table_Character would have fixed fields and fixed record length and so that Time Table would have the consistent date/time format YYYY-DDDThh:mm:ss.ffff. A new PDS4 label was created as part of the migration process. 2014-09-12T15:54:29Z 2014-09-12T15:54:29Z Calibration Calibrated Thruster details for one MESSENGER maneuver migrated from original PDS3 archive to PDS4.
