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 the rugged New Mexico mountain landscape.

After a successful blastoff from New Mexico's Spaceport America on April 28th, the UP Aerospace SpaceLoft XL rocket and its payload nosed into space on a suborbital trajectory.

As part of launch operations, the rocket was tracked by specialists at the neighboring White Sands Missile Range.

While all went well with the flight, the rocket components parachuted into rough-and-tumble terrain. Repeated searches within the landing zone have come up empty.

Jerry Larson, president of UP Aerospace, has told me that the general location of the rocket hardware is known within some 1,300 feet (400 meters) or so.

But given the dense vegetation on the side of the mountain being searched, along with equipment available to the search team, pinpointing the exact locale has proven a tough assignment.

Yet another trip up on the mountain is slated next week, Larson said.

Joining the search this time is the manufacturer of the transmitters onboard the rocket gear. He'll be bringing high — end tracking gear and years of expertise in locating objects in mountain terrain environments.
