What Are Extremophiles
Organisms that live in extreme environmentsExtreme- Places that humans can not normally tolerate
DUDE! THAT’S ME!!!
I’m EXTREMESlide7
Why Study Extremophiles?
Helps to establish a ‘threshold’ for life
Tells us more about the most extreme scenarios where life is possible
We can then apply this information to outer space
Expands the horizons of Viable PlanetsAnalogous for extraterrestrial life
Enables us to look for life in areas where life was previously thought to not be able to surviveHelps us identify what life would be like on other planets, in these extreme environmentsSlide8

As an Astronaut, how would you know these Soil Crusts are alive?
How do you test for life on Mars?ATP!
ATP is the primary product of metabolism and is one of the hallmarks of life
You can test for ATP in several ways
Measuring metabolism (eating food…)ATPmeterRedox dyes for measuring metabolism
First take samples
Hallmark like the card?!Slide17
