"Connecticut-based UP Aerospace, which builds its 20-foot rockets in Highlands Ranch, plans to carry the cremated remains of Mercury astronaut Gordon Cooper as well as those of the actor who played Scotty in the TV series Star Trek, James Doohan. The company's next launch is scheduled for mid-to-late April."
James Doohan's ashes along with the ashes of astronaut Gordon Cooper are supposed to be shot into space on the privately owned Falcon 2 rocket later this year. The rocket is owned by the SpaceX company which is owned by Elon Musk, the co-founder of PayPal.
