Microbes in Space, A Review
Rocco Mancinelli, PI of NAI’s SETI Institute Emeritus Team, and his colleagues have published a major review of space microbiology in the current issue of Microbiology and Molecular Biology Reviews. They discuss that, in general, microorganisms tend to thrive in the space flight environment, but that the mechanisms responsible for the observed behaviors aren’t well understood. The survival of microorganisms in outer space was investigated to tackle questions on the upper boundary of the biosphere and on the likelihood of interplanetary transport of microorganisms. While it is found that extraterrestrial solar UV radiation was the most...

Outer Space Oreos
Scientists have previously exposed organisms and biomolecules to the many rigors of space, but those experiments only managed to take “before” and “after” pictures of their samples. A planned small satellite will monitor on a continuous basis the negative effects of space on biology. The upcoming O/OREOS mission will be the first demonstration flight of the ASTID small payloads initiative.
