Scotty’s space ashes still lost on Earth

Search continues in New Mexico for ‘memorial spaceflight’ payload

The search for the UP Aerospace payload of experiments and the cremated remains of some 200 people — including Scotty of “Star Trek” fame as well as pioneering NASA Mercury astronaut Gordon Cooper — continues within New Mexico’s rugged mountain landscape.
