Astronauts had great success this year in growing lettuce on the ISS (shown above), and now NASA's Veggie program plans to expand to growing space cabbage as well. A variety called Toyko Bekana cabbage was popular among taste-testers on Earth, and scientists think it should be able to grow in the space station's microgravity. Some portion of the space cabbage is expected to get eaten onboard, while the rest will be frozen for further analysis back on Earth.
"We're also working on sending up some Ranch dressing, too," said Gioia Massa, who's heading up the project from NASA's Kennedy Space Center.
Growing crops in space could play an important role in keeping astronauts healthy on the way to Mars, since some nutrients, such as vitamin C, cannot survive over a long time in space.
