 Some bacteria, lichens ("Xanthoria elegans", "Rhizocarpon geographicum" and their mycobiont cultures, the black Antarctic microfungi "Cryomyces minteri" and "Cryomyces antarcticus"), spores, and even one animal (tardigrades) were found to have survived the harsh outer space environment and cosmic radiation.The German EXOSTACK experiment was deployed on 7 April 1984 on board the Long Duration Exposure Facility satellite.30% of "Bacillus subtilis" spores survived the nearly 6 years exposure when embedded in salt crystals, whereas 80% survived in the presence of glucose, which stabilize the structure of the cellular macromolecules, especially during vacuum-induced dehydration.
