For humans to travel to the Moon and Mars, they'll need a companion—a lowly weed. Just as Matt Damon survives on Mars in The Martian
because he cultivates plants in the Red Planet's hostile conditions, astronauts will need to understand how to grow plants in extreme climates. Anna-Lisa Paul and Robert J. Ferl, from the University of Florida, Gainesville Space Plants Lab, put weeds in unique situations—like the International Space Station—to study their behavior on a molecular level. Their research could pave the way for growing plants in extreme climates on Earth, on the moon, during long-term space travel, and even on Mars.
