The first crewed mission of Boeing Co.’s Starliner space capsule has been pushed until at least May 17, following a technical issue that prevented the initial flight on Monday.

After initially saying it would target a launch as early as Friday, the United Launch Alliance sent a later update saying the mission won’t take off before May 17, to allow for the removal and replacement of a pressure regulation valve on a liquid oxygen tanks.
