A Loblolly Pine known as a Moon Tree grew from a seed that was carried to the Moon in January 1971 and brought back to Earth by Major Stuart Roosa, command module pilot for Apollo XIV and a former U.S. Forest Service smoke jumper. Roosa's effort to honor the Forest Service stands as a living tribute. This seed was one of many taken aboard Apollo to study the effects of prolonged weightlessness on seed germination and seedling growth. The Loblolly Pine to the right was planted from a seed from the same cone but was not sent to the Moon.
