When the private SpaceX’s Falcon 9 rocket launched this week, there were some space-lovers aboard. In a wonderful example of the entrepreneurial spirit, the rocket’s operator offered a burial service as part of the flight.

James Doohan, Scotty from “Star Trek,” spent his acting career whizzing through the cosmos. Gordon Cooper was one of America’s famous Mercury seven astronauts. And Bob Shrake spent his work life anonymously helping send NASA’s high-tech spacecraft to other planets.

Now the three men who made space their lives are also making space their final resting place. Their ashes — and those of about 300 others — were aboard SpaceX’s Falcon 9 rocket that blasted into orbit Tuesday as part of an in-space for-profit burial business.
