HOUSTON — NASA on Friday announced the crews of the first flights from U.S. soil since the space shuttle retired in 2011, an elite group of astronauts that the agency hopes will help open a new era of space travel.
The crews would fly on spacecraft developed not by NASA but by two corporations, SpaceX and Boeing, which are under contract to provide a taxi-like service to the International Space Station.
On the first human test flight of Boeing’s Starliner spacecraft, NASA selected astronauts Eric Boe and Nicole Mann will join Boeing executive Chris Ferguson. NASA astronauts Bob Behnken and Doug Hurley would fly on the first human test flight of SpaceX’s Dragon capsule.
On the first operational mission to the International Space Station, Sunita Williams and Josh Cassada would fly for Boeing. NASA astronauts Victor Glover and Michael Hopkins would fly Dragon’s first operational mission to the space station.

Leading up to the a ceremony at the Johnson Space Center here, NASA Administrator Jim Bridenstine said it was a historic moment for the agency: “We are going to launch American astronauts from American soil. That’s a big deal.”
In 2014, Boeing and SpaceX were awarded a combined $6.8 billion in contracts from NASA to develop spacecraft capable of flying crews to the station, the orbiting laboratory.
But both companies have faced setbacks and delays, and on Thursday the agency announced additional schedule slips. While both companies had recently said they would conduct their first test flights with astronauts on board by the end of this year, those flights are now scheduled for 2019.
SpaceX said it would fly crews by April. Boeing said only that it would fly NASA’s astronauts by the middle of next year.

Last week, Boeing confirmed that it had a problem with its launch-abort system, which is designed to ferry crews to safety in the event of an emergency. In a call with reporters this week, John Mulholland, Boeing’s program manager, said that several of the valves failed to fully close, resulting in a propellant leak.
Boeing has since identified the problem, he said, and is working to fix it. “The result is that we’ll have a better and safer spacecraft,” he said.
SpaceX did not give a reason for the delay of its first crewed test flight. But it had been working to resolve an issue with its second stage that caused one of its Falcon 9 rockets to explode while it was being fueled ahead of an engine test.
“Safely and reliably flying commercial crew missions for NASA remains the highest priority for SpaceX,” Benji Reed, SpaceX’s director of crew mission management, said in a statement.
SpaceX, however, moved up the uncrewed test flight of its Dragon spacecraft from December to November of this year.
Since the shuttle was retired seven years ago, U.S. astronauts have had to fly on Russian rockets from a remote launch site in Kazakhstan.

In a recent report, the Government Accountability Office said that further delays in NASA’s “Commercial Crew” program could “disrupt access” to the space station, which would be an enormous embarrassment for NASA after investing about $100 billion to build and operate it.
The report warned that the companies’ schedules are “aggressive” and that they “have set ambitious — rather than realistic — dates, only to frequently delay them.”
