Wm.; Sharkey, B.; Gicquel, A.; Redfern, J. 2026 10.26007/hp5r-3942 This data set contains calibrated data taken by the New Horizons Pluto Energetic Particle Spectrometer Science Investigation instrument during the KEM1 ENCOUNTER mission phase. This version includes observations from prior to, during, and after the ASTEROID 486958 Arrokoth (2014 MU69) encounter. 2025-06-23 2.0 NH SOC: Updated for K7 delivery and liens resolution 2025-01-28 1.0 Created during PDS4 migration by PDS-SBN (B.

The spacecraft is roughly 2.5 meters across and its mass is 465 kg including propellant. Design features include 64 Gbits of redundant solid-state data storage, a 290 m/s propulsion budget, and the capability to transmit data from 32 AU at almost 1 kilobit/second. urn:nasa:pds:context:instrument_host:spacecraft.nh is_instrument_host Pluto Energetic Particle Spectrometer Science Investigation Instrument PEPSSI is a compact particle telescope with a time-of-flight (TOF) section and a solid-state detector (SSD; a.k.a. 'pixel') array. PEPSSI's field of view (FOV) is fan-like and measures 160 degrees x 12 degrees, divided into six angular sectors of 25 degrees x 12 degrees each. Each sector has two SSDs: 3 of the sectors have one electron SSD and one ion SSD each; three sectors have two ion SSDs each. Ions entering the PEPSSI FOV generate secondary electrons as they pass through entrance and exit foils in the TOF section, providing 'start' and 'stop' signals detected by a microchannel plate (MCP). urn:nasa:pds:context:instrument:nh.pepssi is_instrument Solar Wind Plasma Stream urn:nasa:pds:context:target:plasma_stream.solar_wind collection_to_target urn:nasa:pds:context:resource:resource.nh_pepssi_colxn_kem1_raw_online has_resource urn:nasa:pds:context:resource:resource.nh_pepssi_online has_resource urn:nasa:pds:nh_pepssi:kem1_raw:overview::2.0 collection_to_document PEPSSI KEM1 Raw Collection Overview urn:nasa:pds:nh_pepssi:kem1_cal collection_to_data PEPSSI KEM1 Calibrated Data Collection urn:nasa:pds:nh_pepssi:calibration_files collection_to_calibration PEPSSI Calibration Files Collection urn:nasa:pds:nh_documents:mission collection_to_document Document collection for the New Horizons mission. urn:nasa:pds:nh_documents:pepssi collection_to_document Document collection for the PEPSSI instrument. urn:nasa:pds:nh_documents:mission:nhkem1_mission_overview collection_to_document urn:nasa:pds:nh_documents:pepssi:pepssi_ssr collection_to_document Data collection_kem1_raw.csv 0 PDS DSV 1 1444 Line-Feed Comma 2 0 Member Status 1 ASCII_String 1 %1s LIDVID_LID 2 ASCII_LIDVID_LID 255 %-255s inventory_has_member_product
