A team of UA researchers can already “farm” on the red planet with a fully functional prototype greenhouse that produces sweet potatoes and strawberries.
“So, I’ve got to figure out a way to grow three years’ worth of food here — on a planet where nothing grows,” says Mark Watney, the botanist who ends up stranded on the red planet in Ridley Scott’s new film, “The Martian.” (more…)
Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet’s living kingdoms. How did it all begin?
A new study from researchers at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and the Icy Worlds team at NASA’s Astrobiology Institute, based at NASA’s Ames Research Center in Moffett Field, Calif., describes how electrical energy naturally produced at the sea floor might have given rise to life. While the scientists had already proposed this hypothesis — called “submarine alkaline hydrothermal emergence of life” — the new report assembles decades of field, laboratory and theoretical research into a grand, unified picture.
