When our Perseverance rover travels to Mars to search for signs of life, it’s important that the spacecraft doesn’t bring along any Earth bacteria. That’s why @NASAJPL scientist Moogega Stricker is ensuring that the Mars rover is free and clear of microbial stowaways. So if we ever do find life on Mars, we’ll be sure that it didn’t originate on Earth.⁣
