Instrument details
Acronym Nucleon
Full name Coronas-Nucleon
Purpose Space Weather - specifically, particle fluxes in cosmic rays
Short description Several instruments to measure spectra of high-energy cosmic rays to search for evidence of the existence of antimatter, dark matter and other strange forms of matter. Assumed to be similar to PAMELA: protons (0.08-700 GeV), anti-protons, positrons , electrons (0.05-400 GeV), light nuclei (up to Z = 6, i.e. carbon) (0.1-700 GeV/n) and neutrons (0.008-10000 GeV)
Background Follow-on of PAMELA (Payload for AntiMatter Exploration and Light-nuclei Astrophysics) flown on Resurs-DK. Originally intended to be flown as a dedicated satellite (Coronas-Nucleon)
Scanning Technique Interplanetary space observation from a sunsynchronous orbit
Resolution N/A
Coverage / Cycle Nearly full interplanetary space
Mass 300 kg Power Data Rate
