Boeing's crewed Starliner launch delayed again as company says they discover more issues
NASA veteran astronauts Butch Wilmore and Suni Williams are set to launch aboard Boeing's Starliner spacecraft sitting atop ULA's Atlas V rocket. When the scrub was originally called, officials cited the cause as a mechanical issue involving "a liquid oxygen self-regulating solenoid relief valve on the Centaur upper stage" on the rocket.
