Survival of coliphageT1, tobacco mosaic virus (TMV) and spores ofPenicillium roqueforti Thom after direct exposure to space on board 6 balloons, 6 sounding rockets and 3 satellites is related to the numbers of solar UV photons incident during exposure. The survival followed exponential curves leading to complete inactivation. Solar ultraviolet radiation of wavelengths 2000 A to 3000 A appears to be the main cause of inactivation of broth suspended phage and, probably, TMV.T1 phage…

Survival of micro-organisms in space
TLDR
Solar ultraviolet radiation of wavelengths 2000 Å to 3000 Å appears to be the main cause of inactivation of broth suspended phage and, probably, TMV.
Survival of micro-organisms in space
TLDR
Shielding against solar ultraviolet radiation during flight resulted in survival of micro-organisms exceeding to that of the transport controls, and the survival was considered complete.

TLDR
Onboard of several spacecrafts, spores of Bacillus subtilis were exposed to selected parameters of space, such as space vacuum, different spectral ranges of solar UV-radiation and cosmic rays, applied separately or in combination, and their survival and genetic changes after retrieval are studied.

Insights into the Survival Capabilities of Cryomyces antarcticus Hydrated Colonies after Exposure to Fe Particle Radiation
TLDR
Results showed that Cryomyces antarcticus survived in a metabolically active state when subjected to high doses of Fe ions and was able to repair eventual DNA damages, implying that some terrestrial life forms can withstand prolonged exposure to space-relevant ion radiation.

Astromicrobiology or exomicrobiology, is the study of microorganisms in outer space. Microorganisms in outer space are most wide spread form of life on Earth, and are capable of colonising any…
Resistance of Bacillus Endospores to Extreme Terrestrial and Extraterrestrial Environments
TLDR
The molecular laboratory model of spore resistance mechanisms is summarized and attempts to use the model as a basis for exploration of the resistance of spores to environmental extremes both on Earth and during postulated interplanetary transfer through space as a result of natural impact processes.

Bacteria under simulated Martian conditions.
TLDR
Evidence is presented showing that certain bacteria will not only survive, but grow during simulated Martian freeze-thaw cycling if water is present, and a new technique for simulation of known parameters of the Martian environment is discussed along with possible biological implications.

TLDR
The quest for life beyond the Earth can be implemented in three ways: terrestrial biology and organic chemistry, investigate the physical environments of the planets, and determine whether the conditions there are so severe that living processes are entirely excluded, even allowing for the adaptability of life.
Carbon compounds in terrestrial samples and the Orgueil meteorite.
TLDR
Theoretical considerations and experimental data are presented which support the view that alkanes are well constituted to serve as indicators of former life and may provide the clearest insight into the origin of some carbonaceous substances in chondrites.
