If you were hoping to a Boeing Starliner launch to the International Space Station (ISS) today, then you will be disappointed (again). The launch is not expected until Friday May 25 at the earliest.
In a press release, Boeing noted:
The additional time allows teams to further assess a small helium leak in the Boeing Starliner spacecraft’s service module traced to a flange on a single reaction control system thruster. Pressure testing performed on May 15 on the spacecraft’s helium system showed the leak in the flange is stable and would not pose a risk at that level during the flight. The testing also indicated the rest of the thruster system is sealed effectively across the entire service module. Boeing teams are working to develop operational procedures to ensure the system retains sufficient performance capability and appropriate redundancy during the flight. As that work proceeds, NASA’s Commercial Crew Program and the International Space Station Program will take the next few days to review the data and procedures to make a final determination before proceeding to flight countdown.
All we can do is hope and wait. I expect astronauts Suni Williams and Butch Wilmore, who are ready to crew the Starliner, are even more impatient.
Update: The proposed May 25 launch date is now dead as well. NASA has yet to provide a new date for what will be a historic launch if it ever gets underway.
