News about Boeing Starliner

The May 6 launch was scrubbed because of a faulty oxygen relief valve, NASA said. Wilmore and Williams remain quarantined in Houston and will fly back to NASA's Kennedy Space Center in Florida closer to the new launch date, NASA said.

The first launch attempt on May 6 was scrubbed two hours before it was scheduled for liftoff due to concerns over an oxygen-release valve on the United Launch Alliance Atlas V rocket that will transport Starliner into low-Earth orbit, and was initially pushed back to no earlier than May 10.

Live coverage of the event will stream on NASA channels beginning at 6:30 p.m. ET Monday, according to the space agency. Boeing's spaceflight program may reach a significant milestone with the launch of its Starliner spacecraft, carrying two NASA astronauts to orbit.
