If you or a loved one has ever dreamed of traveling into space, but just couldn't quite manage to do it within your lifetime, there's still hope. For a fee, a sampling of a person's cremated remains can be launched into space aboard a rocket, bringing the dream of space flight full circle. Concerned about becoming free-roaming space debris? In most cases, a person's ashes are integrated into a rocket-propelled satellite set to orbit the Earth for weeks or years -- however long it takes before the craft re-enters the Earth's atmosphere, where the satellite and its ashen cargo will be decimated by fire.
The first-ever private launch of last remains into outer space took place in 1997, and carried the ashes of two dozen participants, including "Star Trek" creator Gene Roddenberry and 1960s LSD enthusiast Timothy Leary [source: Celestis]. Since then, hundreds more have made the celestial leap, including James Doohan, the late actor who played Scotty on the long-running "Star Trek" series [source: Allen].
