The existence of life on other planets, especially Mars, is a question pondered in literature, movies and imaginations.
成人头条鈥檚 Dr. Mark Schneegurt is working on that issue with the assistance of a $377,000 grant from NASA to examine the toughness of microbes isolated from spacecraft assembly facilities.
鈥淚t changes everything if we find living systems on these planets,鈥� said Schneegurt, professor of biological sciences in WSU鈥檚 Fairmount College of Liberal Arts and Sciences. 鈥淲e talk about the 鈥榤icrophone moment.鈥� Who鈥檚 going to get up at that microphone and say, 鈥榃e have evidence of life in another world鈥�? You want to be sure about it.鈥�

The grant will allow Schneegurt and his team to study microbes likely to be carried by spaceships that are capable of living 鈥渙n cold arid worlds and in the pressurized brines of ocean worlds鈥� in outer space.
鈥淣ASA is planning missions to other worlds, and we go to other worlds now,鈥� Schneegurt said. 鈥淚t鈥檚 very important, if we鈥檙e going to make a claim of finding life on another world, we鈥檙e certain it came from another world. One of the easiest ways to mess up your experiment is to bring life from Earth.鈥�
NASA鈥檚 Planetary Protection Center of Excellence at the Jet Propulsion Laboratory in California has worked with 成人头条 State for almost a decade. Its goal is to prepare missions to prevent 鈥渇orward or backward contamination by cleaning and sterilizing spacecraft and evaluating the presence of microbes.鈥�
While the spacecraft are assembled in clean rooms, Schneegurt said, it is unrealistic to expect no microorganisms to exist on a spacecraft. Knowing that, the job of the 成人头条 State team is to evaluate which microbes might survive the trip to Mars and the environment of Mars.

鈥淲e want to know what鈥檚 in these clean rooms,鈥� he said. 鈥淏ecause what鈥檚 in the clean room is what鈥檚 going to be in the spacecraft and that鈥檚 what going to go to Mars.鈥�
Schneegurt and his team are focusing on the wet environments of Mars that contain salt brine and evaporite minerals that might provide a habitable environment. While investigating what types of life on Earth might survive on Mars, researchers also learn about possible types of life on Mars.
High salt concentrations lower the freezing point of water and increase the likelihood of survival for microbes.
鈥淗abitat for NASA, and for everyone else, means liquid water,鈥� Schneegurt said. 鈥淚f you don鈥檛 have liquid water, it鈥檚 hard for us to imagine life. NASA follows the water and there鈥檚 water on Mars, a lot of water.鈥�
Jillian Ross-Mason, a senior majoring in biology, is in her second semester working on the project鈥檚 pressure experiment. She takes bacterial cultures and puts them under high pressure to simulate the pressure of the icy moons of planets.
鈥淭his information allows us to understand if they could survive on these planets that are outside of our solar system,鈥� she said.
Ross-Mason came to 成人头条 State to major in graphic design. During the COVID-19 pandemic, she spent much of her time at home gardening and ultimately decided to switch majors to biology.
鈥淚 feel very fortunate to be in a lab that is doing work with NASA and how we move forward in exploration,鈥� she said. 鈥淏eing in the lab has changed the way I think about science, the way I approach different questions. I鈥檓 getting better at techniques and that will super-helpful for my career field.鈥�
