Episode 419 - Testing life on Mars here on Earth

February 22, 2021

Perseverance has landed and begun it's long mission, but how can scientists on Earth help research on Mars? Can we study life on Mars here on Earth? Robotic missions aren't the only way Martian rock has made it's way to Earth. Rare meteorites from Mars can be used to test how life would grow in Martian soil. Just how old is the Jezero crater? Can you date a crater without doing detailed tests? How does measuring lunar craters help us put a date on the age of Martian craters like Jezero?
