Science is Fun Fridays!

Astronaut Suni Williams just completed the longest spacewalk time for a female.

Part of her mission, along with astronaut Butch Wilmore, was to swab the surface material around the airlock and outside the Destiny laboratory.

The ISS External Microorganisms investigation has been ongoing - with previous samples collected back in June.

There are life support vents outside the Destiny module, and scientists want to examine whether a spacecraft releases microorganisms, and if so, how many and how far they may travel.  Can they survive, even thrive, out there?

Lichens, bacteria, tardigrades and more have been shown to be able to withstand the harsh space conditions - no air, lots of cosmic radiation, and temperatures from about 250 to -250 degrees F.
