NASA has selected four astronauts to train and prepare for commercial spaceflights that will return American launches to U.S. soil and further open up low-Earth orbit transportation to the private sector. The selections are the latest major milestone in the Obama Administration’s plan to partner with U.S. industry to transport astronauts to space, create good-paying American jobs and end the nation’s sole reliance on Russia for space travel.

“I am pleased to announce four American space pioneers have been selected to be the first astronauts to train to fly to space on commercial crew vehicles, all part of our ambitious plan to return space launches to U.S. soil, create good-paying American jobs and advance our goal of sending humans farther into the solar system than ever before,” said NASA Administrator Charles Bolden. “These distinguished, veteran astronauts are blazing a new trail — a trail that will one day land them in the history books and Americans on the surface of Mars.”

NASA named experienced astronauts and test pilots Robert Behnken, Eric Boe, Douglas Hurley and Sunita Williams to work closely with The Boeing Company and SpaceX to develop their crew transportation systems and provide crew transportation services to and from the International Space Station (ISS).
