Algae transformed Earth. Next stop: Mars?

Since the very beginning of the space age, people have been wondering if algae could provide a life support system beyond our planet. From dozens of studies over the last 60 years, we’ve figured out that algae probably can thrive for up to a year in space. But what if we wanted to live permanently on another planet, like Mars? This episode is all about algae: how it shaped early Earth, how we might use it to terraform planets in the future, and how it’s being used in biomanufacturing to hopefully get us away from relying on fossil fuels.
