The Biostack experiment precisely measured space radiation's biological effects on organisms. It revealed how cosmic rays and microgravity impact life in space, advancing space biology research.

Area of Science:

  • Space Biology
  • Radiation Biology
  • Astrobiology

Background:

  • European space life science research began in 1972 with the Biostack experiment.
  • The Biostack program investigated the biological impacts of cosmic radiation in space.

Purpose of the Study:

  • To investigate the biological effects of single heavy ions from cosmic radiation.
  • To determine the precise spatial correlation between heavy ion passage and biological responses.
  • To assess the influence of spaceflight factors like microgravity on radiation effects.

Main Methods:

  • Utilized the Biostack experiment on Apollo 16 and subsequent missions.
  • Measured the biological response of single test organisms to individual heavy ions.
  • Recorded the spectrum of charge and energy of cosmic radiation.
