A race against time to find Apollo 14's lost voyagers

nd. A simple sign nearby read "moon tree."

"At the time, I had never heard of moon trees," Williams says. "The sign had a few clues, so I sent a message to the NASA history office and found more bits and pieces on the web. Then I got in touch with Stan Krugman and got more of the story."

Krugman had been the U.S. Department of Agriculture Forest Service's staff director for forest genetics research in 1971. He had given the seeds to Roosa, who stowed them in his personal gear for the Apollo 14 mission. The seeds were symbolic for Roosa because he had fought wildfires as a smoke jumper before becoming an Air Force test pilot and then an astronaut.

The seeds flew in the command module that Roosa piloted, orbiting the moon 34 times while astronauts Alan Shepard Jr. and Edgar Mitchell walked -- and in Shepard's case, played a little golf -- on the moon.

Back then, biologists weren't sure the seeds would germinate after such a trip. Few experiments of this kind had been done. A mishap during decontamination procedures made the fate of the seeds even less certain: the canister bearing the seeds was exposed to vacuum and burst, scattering its contents.

But the seeds did germinate, and the trees seemed to grow normally. At Forest Service facilities, the moon trees reproduced with regular trees, producing a second generation called half-moon trees.

By 1975, the trees were ready to leave the Forest Service nurseries. One was sent to Washington Square in Philadelphia to be the first moon tree planted as part of the United States Bicentennial celebrations; Roosa took part in that ceremony. Another tree went to the White House. Many more were planted at state capitals, historic locations and space- and forestry-related sites across the country. Gerald Ford, then the president, called the trees "living symbol[s] of our spectacular human and scientific achievements."
