New Horizons PEPSSI Pluto Encounter Calibrated Data

A PDS3 version of this data set can be found here.

Status: LOCALLY ARCHIVED

Abstract: This data set contains Calibrated data taken by the New Horizons Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) instrument during the PLUTO ENCOUNTER mission phase. These data were migrated from the PDS3 dataset: NH-P-PEPSSI-3-PLUTO-V3.0. During the Pluto Charon Encounter mission phase starting in January, 2015, there were several sub-phases: three Approach sub-phases, (AP1, AP2 and AP3); a CORE sequence for the Pluto flyby on 14 July, 2015 (Day Of Year 195), sometimes also referred to as NEP (Near-Encounter Phase); three Departure sub-phases (DP1, DP2, DP3); a Transition sub-phase ending in late October, 2016, closing out the Pluto Encounter mission phase. For this final PEPSSI delivery for the Pluto mission phase, this data set includes the Approach data plus the CORE and Departure sequences' data, as well as normal operation and Calibration Campaign data during Transition, and has all data downlinked through the end of October, 2016. Due to a spacecraft safing event on 04 July, 2015 (DOY 185), the balance of the science load from then-executing 15184 sequence (nominal start time on DOY 184 in 2015) was sacrificed to ensure the 15188 CORE load with the flyby sequence could be loaded onto the spacecraft and started on time. As a result, there is a gap in the PEPSSI data from approximately DOY 186 to DOY 188. Labels were redesigned during migration using the .FIT header and PDS3 .LBL files, but the data files are unchanged from their PDS3 version.
