Government watchdog warns Boeing, SpaceX delays may cut US astronauts off from International Space Station

NASA's program to launch U.S. astronauts with Boeing and SpaceX is likely to be delayed further, the Government Accountability Office said in a report published Wednesday. "Additional delays could result in a gap in U.S. access to the space station," the government watchdog says. NASA "does not have a contingency plan for ensuring uninterrupted U.S. access," the GAO said.
