Russian Segment of ISS Adjusts BTN-M2 Equipment Configuration, Continues Neutron and Gamma Radiation Observations
On August 13, 2026, during the ISS-75 expedition mission, Russian cosmonauts Pyotr Dubrov and Anna Kikina performed configuration adjustments to the BTN-M2 scientific equipment inside the Nauka module of the Russian Segment of the International Space Station. Figure 1. Profiles of gamma rays (energies below 500 keV, black curve), 511 keV photons from electron-positron annihilation (green curve), and high-energy neutrons (red curve) detected by the BTN-M2 instrument aboard the ISS on July 30–31, 2026. Red arrows indicate enhanced gamma-ray flux during the solar proton event (SPE) as the ISS passed over high-latitude regions of the Earth...
