"The laugh factor on this was really intense," says Spencer, founder of the Space Tourism Society, an advocacy group based in West Los Angeles. But with corporate visionaries pouring millions of dollars into the building blocks of such an industry, Spencer says, few people are laughing now. "It's happening," he says. "There's a market.
