"To get a peek at how commercial space will prepare its people, I signed up for private astronaut training, a three-day NASTAR certificate course for suborbital researchers. Founded in 2006, NASTAR began as a showcase for its parent company, Environmental Tectonics Corp., a leading maker of flight simulators. In 2010 it won Federal Aviation Administration approval for private space training, the first company to do so. The course remains optional, but regulators may require it as part of a company's license. "We're basically leaving it up to the companies," says George Nield, associate administrator for the FAA's office of commercial space transportation."
