ALTEINO Experiment

ALTEINO experiment is included in the Italian scientific and technological program Marco Polo, which is a constituent part of the Russian Program for Implementation of Scientific and Technological Research Planned for the Fourth Manned Expedition ISS-4.


To study the mechanisms of effects of heavy charged particles in cosmic radiation and the phosphenes (light flashes) that they create on visual analyzers and central nervous system of the cosmonaut and his capacities as an operator in space flight environment.


  • radiology studies in the field of space particle physics;
  • electrophysiology studies of the level of total effects of space flight on the functional state of the cosmonaut's central nervous system.

Scientific Equipment Used:

  • AST spectrometer to measure angle, charge and energy properties of heavy ions (nuclei) in cosmic radiation.
  • Halley package (portable electroencephalograph) to support pick-up, amplification, and analog-to-digital conversion of electrophysiological signals (up to 16 channels), recording and storing data on PCMCIA cards consisting of:
    - Halley device;
    - dictaphone;
    - event indicator;
    - mask;
    - belt.
  • ALTEINO-PM kit:
    - headpiece with electroencephalograph;
    - batteries;
    - a set of electrodes.


  • PCMCIA memory cards;
  • MC-60 mini-cassettes for dictaphone.

Expected Results:

Obtaining the data on the radiation safety of cosmonauts during long-duration and long-range missions, as well as the dynamics of their central nervous system functional state and changes in the level of their capacity as operators under these conditions. Determining the level of radiation protection in working compartments of ISS RS more precisely.
