Starliner launch scrubbed; no launch date yet set
For reasons that have not yet been revealed, ULA scrubbed today’s unmanned demo test flight of Boeing’s Starliner capsule just prior to launch, rescheduling the launch for tomorrow.
The launch tomorrow wiill occur at 12:57 am (Eastern).
UPDATE: It appears the scrub occurred because of a valve issue in the propulsion system of Boeing’s Starliner capsule.
“During pre-launch preparations for the uncrewed test flight of the CST-100 Starliner spacecraft, Boeing engineers monitoring the health and status of the vehicle detected unexpected valve position indications in the propulsion system,” the company said in a statement. “The issue was initially detected during check outs following yesterday’s electrical storms in the region of Kennedy Space Center.”
…The propulsion system valves in question are inside the Starliner’s service module, which has an array of rocket thrusters designed to propel the spacecraft away from its launcher during an in-flight emergency. Other thrusters on the service module are used for in-orbit maneuvers and spacecraft pointing control.
Boeing cannot afford more failures during this second demo flight. The company has been plagued with numerous debilitating technical failures during the past four years, from Starliner to its airlines. Right now the failure to get Starliner operational is losing them business in the emerging orbital tourist market. They need to get it working, and working reliably.
UPDATE: They have decided to cancel the launch plans for tomorrow, to roll the rocket back into the assembly building so they can do more tests on the capsule’s service module where the troublesome valves are.
