This sycamore tree was planted in 1977 and grew from a seed that traveled around the moon. As part of a NASA/US Forest Service collaboration, Apollo 14's command module carried this seed and hundreds of others into space in early 1971 to study the effects of prolonged weightlessness on the ability of seeds to germinate and grow. Upon the return to Earth, the US Forest Service germinated the seeds and dispersed the seedlings all over the country and beyond. Many were planted to commemorate the US bicentennial. In June 1977, the NASA Goddard Space Center planted this sycamore shortly after the opening of its visitor's center.

This tree's seed was one of many that traveled into space in the Apollo 14 command module in 1971 as part of a joint project between NASA and the US Forest Service. While Alan Shepard and Edgar Mitchell walked on the surface of the moon in February 1971, astronaut Stuart Roosa, a former US Forest Service wilderness firefighter, orbited the moon in the Apollo 14 command module, "Kitty Hawk." In the module were hundreds of seeds of loblolly pine, sycamore, sweetgum, redwood, and Douglas fir trees. Control seeds of these species were maintained on Earth for later comparison.

Stan Krugman of the US Forest Service, who managed the project, sent the seeds that had returned from space to stations in Gulfport, Mississippi and Placerville, California to attempt germination. The seed canisters had burst open upon their return during decontamination, so they were assumed not to be viable, but surprisingly over 400 seedlings grew. Many were planted around the United States for the nation's bicentennial in 1976. Some were planted alongside the control seeds, and after several decades there was no observable difference between the earthbound seeds and those which had orbited the moon. No list or systematic tracking of the moon trees exists, though Dr. David R. Williams at NASA has been compiling a list of known "moon trees."

On June 9, 1977, shortly after the opening of the Goddard Space Flight Center's Visitor Center in Greenbelt, Maryland, this sycamore (Platanus occidentalis) moon tree was planted. The tree now stands over 50 feet high.
