Back in 1971, NASA astronaut Stuart Roosa set out on the Apollo 14 mission, becoming one of the 24 people to travel to the Moon. On the outing, he brought along 500 tree seeds as a praise to the U.S. Forest Service.
The agency, for which Roosa had previously dished as a firefighter, had meditated about how being in space would affect tree seeds — namely, whether they’d be allowed to bud back on Dirt. The Apollo 14 mission presented itself as the perfect given an opportunity to evaluation it out, so they took advantage and asked for Roosa’s help. He was more than happy to participate in their venture, producing seeds from five all kinds of trees into path with him. Many would afterwards grow into “Moon trees.”
After the mission, virtually all of the grains germinated back at the Forest Service depots in Mississippi and California. Most of the seedlings were then sending them to government forestry organizations to be planted within the framework of the 1976 Bicentennial observance, but some impelled their highway to the White House, Brazil, Switzerland, and the Emperor of Japan.
