“15 years after NASA astronomer David Williams started searching for them, hundreds of trees grown from space-faring seeds are still missing. The
moon trees, whose seeds circled the moon 34 times in Apollo 14 astronaut Stuart Roosa’s pocket, were welcomed back to Earth with great fanfare in 1971. One was planted in Washington Square in Philadelphia as part of the 1975 bicentennial celebrations. Another took root at the White House. Several found homes at state capitals and space-related sites around the country. Then-president Gerald Ford called the trees ‘living symbol[s] of our spectacular human and scientific achievements.’ And then, mysteriously, everyone seemed to forget about them.”
