Searching for extremophiles, want to come? 🦠🔎 Join us on June 13 as @NASA_Astronauts swab for microbial life on the outside of @Space_Station during their spacewalk. Live coverage on NASA+ begins at 6:30 am ET. go.nasa.gov/3U6j8PA pic.twitter.com/g9aXo1Swy1

Astronauts will swab outer surfaces of @Space_Station to learn if station releases microbes and, if so, how far they travel. Samples could inform what microorganisms can survive the harsh space environment and potentially contaminate planetary bodies visited on future missions. pic.twitter.com/ZUloPuWdot
