Bacillus safensis

Bacillus safensis

Where we found it: On a Mars Exploration Rover before launch (2004)at the Jet Propulsion Laboratory (JPL-NASA, Pasadena, CA)

Why it's awesome: This microbe was first discovered and characterized in the “clean” rooms where spacecraft are assembled at JPL.

Fun fact: This salt-tolerant microbe has been sent into space before, but on a Russian mission that failed during launch.
