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…)
The sun and the solar system’s rocky inner planets, including the Earth, may have formed differently than previously thought, according to UCLA scientists and colleagues analyzing samples returned by NASA’s Genesis mission.

And although the differences are slight, the research could help determine how our solar system evolved. (more…)
