Groups of trees that don’t stand up straight are sometimes called “drunken forests.”
There are several dozen trees living in the U.S. that have been to the moon.
In February 1971, NASA astronauts Alan Shepard and Edgar Mitchell landed on the moon at the apex of the Apollo 14 mission. Astronaut Stuart Roosa was orbiting overhead in the command module, and packed away in his personal kit were seeds from five tree varieties — loblolly pine, sycamore, sweetgum, redwood, and Douglas fir. This lunar journey was part of a joint experiment between NASA and the U.S. Forest Service to test the effects of zero gravity on seeds and their subsequent growth into trees. After Apollo 14 returned safely to Earth, these seeds were eventually planted throughout the U.S., where they became known as “moon trees.” One was planted at the White House, and many others throughout the country in state capitals and parks. (Scientists never found evidence that their trip to space had affected the seeds or trees.) The project was mostly forgotten as the fervor surrounding the Apollo program subsided, but in 1996 NASA astronomer and archivist David Williams received an e-mail from a third grade teacher in Indiana about a nearby “moon tree.” Fascinated by this lost piece of NASA history, Williams began cataloging the location of these arboreal space voyagers. Today, you can visit several dozen “moon trees” that are surviving and thriving across the U.S.
