(AP) — NASA expects to save millions of dollars sending astronauts to the International Space Station, once its commercial crew program starts flying in a couple of years. U.S. manned launches ended with the retirement of the space shuttles in 2011. [...] SpaceX and Boeing begin flying crews from Cape Canaveral, NASA astronauts must continue to hitch rocket rides with Russia. NASA's commercial crew program manager, Kathy Lueders, said the average price for a seat aboard the SpaceX Dragon and Boeing CST-100 capsules will be $58 million. Unlike the Russian charge, the $58 million per-person cost estimate includes a fair amount of cargo to be flown aboard the SpaceX and Boeing spacecraft, along with four crew members. Boeing's vice president and general manager for Houston-based space exploration, John Elbon, said an unmanned test flight of the CST-100 capsule in 2017 will be followed a few months later by the first crewed test flight.
