NASA’s Phoenix Mars Lander discovered that a sample of Martian dirt contained several soluble minerals, including potassium, magnesium and chloride. This means the soil in Mars may have enough nutrients to grow plants. Asparagus would grow happily in it, scientists say.
BBC reports: “We basically have found what appears to be the requirements for nutrients to support life,” said Phoenix’s wet chemistry lab lead, Sam Kounaves of Tufts University. “This is the type of soil you’d probably have in your backyard. You might be able to grow asparagus pretty well, but probably not strawberries.”
