NASA-Boeing to Delay Starliner Launch

August 3, 2021

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 issue was initially detected during check outs following yesterday’s electrical storms in the region of Kennedy Space Center.

Consequently, the launch of the Starliner spacecraft to the International Space Station atop a United Launch Alliance Atlas V rocket will be postponed. The launch was scheduled for 1:20 p.m. ET on Tuesday, Aug. 3. Boeing and NASA teams are assessing the situation. The team will provide updates regarding a launch attempt on Wednesday, Aug. 4.

“We’re disappointed with today’s outcome and the need to reschedule our Starliner launch,” said John Vollmer, vice president and program manager, Boeing’s Commercial Crew Program. “Human spaceflight is a complex, precise and unforgiving endeavor, and Boeing and NASA teams will take the time they need to ensure the safety and integrity of the spacecraft and the achievement of our mission objectives.”

Updates will be provided by NASA and Boeing as information is analyzed and confirmed.
