Did you know that scattered around our planet are hundreds of creatures that have been to the Moon and back again. None of them are human. And most are missing. They're trees. Moon trees. Moon trees are trees grown from 500 seeds taken into orbit around the moon by astronaut Stuart Roosa during the Apollo 14 mission in 1971.
Most of the Moon trees were given away in 1975 and 1976 to many state forestry organizations, in order to be planted as part of the nation's bicentennial celebration. Trees were also planted in Brazil, Switzerland, and Japan. Today it's not known where all the trees were planted because nobody kept a record. NASA scientist Dave Williams has found some of them and he's looking for more.
