Doohan of 'Star Trek' Off to Space
Star Trek actor James Doohan's last wishes are set to be granted on December 6, when his cremated remains are launched into space. Commercial space flight operator Space Services Incorporated will launch the late actor's remains into space aboard its Explorers Flight, according to a company spokeswoman. She adds that the remains of more than 120 others will be aboard the flight, including those of an unidentified astronaut and Mareta West, the astrogeologist who determined the site for the first spacecraft landing on the moon. Doohan, who portrayed chief engineer Montgomery 'Scotty' Scott on the Star Trek TV series, died in July at the age of 85. To mark the flight into his final frontier, Doohan's family will hold a service for fans on a site near California's Vandenberg Air Force Base on the day of the launch. The actor's widow, Wende Doohan, says, "I can't think of a more fitting send-off than having some of his fans attend this, his final journey." Doohan's cremated remains will be packed into a special tube which will be ejected from the rocket and expected to orbit Earth for about 50 to 200 years before plunging into the planet's atmosphere and burning up.
