Аннотация:The article discusses the “MODULATION” project, which is supposed to be implemented aboard the Russian space station ROSS. The purpose of the space mission is to study the solar modulation of galactic cosmic rays (GCR) in the heliosphere. A new approach is presented to obtain accurate long-term measurements of GCR particle fluxes, as well as solar cosmic rays (SCR), with energies from 30 to 1500 MeV/nucleon in the wide charge range. The project describes a new method for measuring the energy of cosmic particles, which makes it possible to create a lightweight and compact but precision instrumentation that will allow measuring not only the energy but also the direction of arrival of cosmic rays. The project involves the creation of a data bank of GCR and SCR data for the entire solar activity cycle. Such a bank is necessary to improve numerical models of the fluxes of energetic heliospheric particles.
