SUMMARY: An experiment recovered from the wreckage of the space shuttle Columbia has given researchers valuable insights into how plants behave when they're growing in space. Experimenters were expecting common roof moss to grow in random, confused directions, but instead it grew in an ordered spiral pattern. On Earth, gravity controls the growth of moss so that it grows directly away from the centre of the planet. It's possible that this spiral direction is a backup growth response that existed before the moss evolved the ability to detect gravity. Unfortunately, only 11 out of 87 cultures were salvageable from the Columbia's wreckage.
