Moon tree
Moon trees are trees grown from 500 seeds taken into orbit around the Moon by Stuart Roosa, the Command Module Pilot on the Apollo 14 mission in 1971. Roosa, who had been a smoke jumper, was contacted by Ed Cliff, the Chief of the Forest Service[1] at the time, with the idea of taking the seeds along. Seeds for the experiment were chosen from five different species of trees: loblolly pine, sycamore, sweetgum, redwood, and Douglas fir.[2]




The seeds orbited the Moon, but were not landed on it.
Roosa’s daughter, Rosemary Roosa, continues on his work with the “Moon Tree Foundation.”

After the flight the seeds were sent to the southern Forest Service station in Gulfport, Mississippi, and to the western station in Placerville, California, with the intent to germinate them. Nearly all the seeds germinated successfully, and the Forest Service had some 420 seedlings after a few years. Some of these were planted alongside their Earth-bound counterparts, which were specifically set aside as controls. After over forty years there is no discernible difference between the two classes of trees. 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. Since the trees were all of southern or western species, not all states received trees. A Loblolly Pine was planted at the White House, and trees were planted in Brazil, Switzerland, and presented to Emperor Hirohito, among others.[2]
In March 2021, the Royal Astronomical Society and the UK Space Agency asked for the help of the public to identify up to 15 Moon Trees that may be growing in the United Kingdom. As of April 2021, none of the trees that supposedly came to the UK have been identified.[3]
