Translations:Bacillus subtilis/28/en

Since the 1960s B. subtilis has had a history as a test species in spaceflight experimentation. Its endospores can survive up to 6 years in space if coated by dust particles protecting it from solar UV rays. It has been used as an extremophile survival indicator in outer space such as Exobiology Radiation Assembly, EXOSTACK, and EXPOSE orbital missions.
