About 500 seeds of different tree species were launched into space in 1971 that circled around the moon 34 times before returning to Earth where they were then planted in different spots around the globe.
NASA has shared a map showing the locations of these 'Moon Trees,' which total to 83 that mainly reside in the US, with two in South America and one in Europe.
The collection includes redwoods, Douglas firs, sycamores, sweetgums and loblolly pines, but about a third have died since being planted in the 1970s.
The mission was part of Apollo 14 and while astronauts Alan Shepard and Edgar Mitchell walked on the moon, Stuart Roosa orbited above in the command module with the seeds that sat his personal kit.

This year marks the 50th-anniversary of the Apollo 14 mission, which was the third to land on the moon and first to land in the lunar highlands.
During the mission, the seeds were classified and sorted, and control seeds were kept on Earth to be a comparison.
The space seeds were placed in Rossa's kit, but the canister burst open during the decontamination procedure after the crew returned to earth, leaving many unusable for the experiment.
'The resulting seedlings were planted throughout the United States (often as part of the nation's bicentennial in 1976) and the world. They stand as a tribute to astronaut Roosa and the Apollo program,' NASA shared in a statement.

Dr. Michele Tobias of the University of California Davis created a detail map of Moon Trees around the world.
'A few months ago I learned about Moon Trees watching an episode of Huell Howser on KVIE Public Television and then visited the one on the California State Capitol grounds,' Tobias said in 2016.
'I later learned from my aunt that my grandfather was a part of the telemetry crew that retrieved the Apollo 14 mission that carried the seeds that would become the Moon Trees, so there's something of a connection to this idea.'
NASA put the seeds in the care of the US Forest Service, which watched over them until they sprouted - but some were not planted until years after the mission.

In a telegram to US Bicentennial Moon Tree planting ceremonies, then-President Gerald Ford said: 'This tree which was carried by Astronauts Stuart Roosa, Alan Shepard, and Edgar Mitchell on their mission to the Moon, is a living symbol of our spectacular human and scientific achievements.'
'It is a fitting tribute to our national space program which has brought out the best of American patriotism, dedication, and determination to succeed.'
However, over the years the public forgot about the trees, along with NASA, but former astronaut David Williams made it his personal mission in 1996 to find and catalog them all.
He started off with a list of 22 Moon Trees and had tracked down 80, although of those 21 have died.
Three more have recently been added to the list, bringing the total to 83, but a third are now dead.
However, William said that the fate of many trees likely had nothing to do with their trip to space.

Compared with seeds that never blasted off, 'there was no detectable difference at all, which is what anyone would have expected,' Williams told Atlas Obscura.
A Loblolly Pine was planted at the White House, and trees were planted in Brazil, Switzerland, and presented to the Emperor of Japan, among others.
Trees have also been planted in Washington Square in Philadelphia, at Valley Forge, in the International Forest of Friendship, and at various universities and NASA centers
Along with others at Goddard Space Flight Center in Greenbelt, Maryland
The first Moon tree, a sycamore, was planted in 1974 at Camp Iti Kana, a recreational site used by Girl Scouts of Mississippi.
