"Boeing said Tuesday that it has pushed the date of its first manned space mission back from 2017 to 2018. Boeing's CST-100 Starliner, which will carry the astronauts, is still under development. SpaceX, led by Tesla Motors (TSLA) CEO Elon Musk, says it intends to have a manned mission in 2017 using its Dragon space capsule. Unlike the Starliner, Dragon is already built and in use, delivering supplies to the International Space Station with unmanned missions. But it will need to go through further testing before it can carry humans."
"However, if both companies stick to their stated schedules, SpaceX would become the first U.S. commercial venture to send astronauts to the space station and as a result would take possession of a highly prized trophy: a U.S. flag that was left aboard the station by the last space shuttle crew in 2011."
