Mission Name: Mars 5The objective of the Energetic Particles experiment was to measure proton fluxes during the cruise to Mars. The S-18-5M instrument was designed as a monitor of charged particles of medium energies travelling in the interplanetary space. There were six sensors: a gas-discharge counter D1 of the STS-5 series, and a Cherenkov counter D2 (30x30 mm plexiglas), and four SSD (Si) detectors: D3, D5 of ~30 micron thickness and D4, D6 of ~400 micron thickness.
This experiment was one of several provided by the Theoretical and Applied Space Physics Division of the Skobeltsyn Institute of Nuclear Physics of Moscow State University. The experiments flew on the Soviet Zond, Luna, Mars, Venera, Vega, and Phobos interplanetary/planetary missions and measured energetic (MeV) particles in the interplanetary medium. The earliest missions (Zond 1 and 3) measured protons above 30 MeV. Later missions measured lower energy protons and some also measured fluxes toward and away from the sun.

Data from all these experiments, unknown to NSSDC before 1999, were prepared at MSU and provided to NSSDC in 1999 in ASCII formats.
