British singer Sarah Brightman is scheduled to begin training this year for a 2015 flight to the International Space Station where she hopes to become the first professional musician to sing from space, the company arranging the trip said on Tuesday. Brightman, a famed soprano who starred in Andrew Lloyd Webber’s ‘Phantom of the Opera,’ will pay about $52 million for a 10-day stay aboard the orbital outpost, Tom Shelley, president of privately owned Space Adventures, said. ‘She’s absolutely 100 percent committed,’ Shelley said during a National Space Club Florida Committee meeting.
