In 2005, scientists announced that moss could grow inside of spaceships . The little plants the scientists sent up on NASA Space Shuttle missions grew in a breathtakingly weird shape, a sort of fuzzy spiral, an apparent reaction to the low-gravity environment.

It was not as whimsical an experiment as you might think. As researchers contemplate how humans might someday feed ourselves beyond Earth, it’s anyone’s guess how plants that evolved on Earth, with Earth’s gravity and atmosphere and protection from the radiation of outer space, will handle such strange habitats.

Since that space moss took its journey, many research teams have sent seeds and spores to the International Space Station (ISS) and arranged for plants to be grown there . Now, following in the steps of those researcher
