NASA names astronauts for first manned U.S. space launches since 2011

NASA on Friday named nine astronauts for the first manned space launches from U.S. soil since the space shuttle program ended in 2011. The National Aeronautics and Space Administration's announcement signals a milestone in the U.S. space program, with its shift to the private sector for ferrying cargo and astronauts to the International Space Station. Since the space shuttle program was shut down, the U.S. space agency NASA has had to rely on Russia to fly astronauts to space station, a $100 billion orbital research laboratory that flies about 250 miles (402 km) above Earth.   The astronauts named on Friday will be carried aloft aboard spacecraft developed by entrepreneur Elon Musk's SpaceX and Boeing Co, crewing first the test flights, and then missions involving both Boeing's CST-100 Starliner and SpaceX's Crew Dragon.
