Bacillus safensis |
Bacillus safensis is a bacterium, highly resistant to gamma and UV radiation, that has raised some concerns over a possibility of having been brought to the planet Mars with the two space probes Spirit and Opportunity in 2004.
The bacterium is named after the NASA Jet Propulsion Laboratory’s Spacecraft Assembly Facility (SAF) where it was first discovered.
