urn:nasa:pds:nh_pepssi 4.0 1.19.0.0 Product_Bundle 2026 This bundle contains collections of raw and calibrated data from the PEPSSI instrument onboard the New Horizons spacecraft, as well as a calibration collection of ancillary files used to calibrate the data from raw to processed. 2026-03-06 4.0 (NH SOC) Added KEM2 and updated KEM1 collections for K7 delivery. 2025-12-16 3.0 (SBN:T. Barnes) Adding the Raw/Calibrated collections from the PDS4 migration by PDS-SBN for the Launch Checkout, Jupiter Encounter, Pluto Cruise, and KEM1 Cruise mission phases. 2025-05-19 2.0 (SBN:T. Barnes) Adding Pluto Encounter Raw/Calibrated collections from PDS4 migration by PDS-SBN. Updated the readme.txt file to be more generic. 2025-01-28 1.0 Created during PDS4 migration by PDS-SBN (B. Sharkey).

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 urn:nasa:pds:context:resource:resource.nh_pepssi_online has_resource urn:nasa:pds:nh_documents:mission bundle_to_document Document collection for the New Horizons mission. urn:nasa:pds:nh_documents:pepssi bundle_to_document Document collection for the PEPSSI instrument.
