Q: When will these new private spacecraft take astronauts into space? A: There are several companies vying for the job, all with different timetables. Many haven't finished building test rockets. SpaceX's mastermind, Elon Musk, co-founder of PayPal, is aiming to launch a crew by 2015; other firms are targeting 2016 or 2017. A good rule of thumb in the rocket business: Few early flights go even close to schedule. Q: Will others be able to fly in space or just astronauts? A: Private space companies are counting on real people as paying customers in space tourism eventually, but it won't be cheap. Still, experts say commercial space firms are probably the only way everyday people will get to space.
