Anatomy of Next returns, and we design the Martian forests and fields. We've built an atmosphere on Mars, warmed the planet, and jumpstarted it's hydrologic cycle — from a frozen, irradiated desert to thunderstorms on a warm equator. Now, what about life? How do you grow crops on sterile, toxic soil with limited carbon and nitrogen? We talk to experts in microbiology and genetic engineering, and we start our work on ecohacking the once red — now blue — Planet Mars.
