Also called: Extremophile Microbiologist

Searches for signs of life beyond Earth by studying microbes that survive in extreme places.

A day in the life

Collects microbes from boiling hot springs in Yellowstone or ice in Antarctica, then tests whether they could survive Mars-like conditions in a lab chamber. Helps plan instruments for NASA missions.
