Boeing Starliner Launch Delayed Again Due to Helium Leak Troubleshooting

ai generated text

The first crewed launch of Boeing's Starliner spaceship to the International Space Station (ISS) has been postponed due to a minor helium leak in the propulsion system. The delay was prompted by the discovery of the issue, which is being resolved before the next attempt on May 21 at the earliest. Initially, the mission was set for May 17, but it was already delayed once after two astronauts were strapped in and ready to fly. According to officials, the leak is small and engineers need more time to get comfortable with it before proceeding. The issue was traced to a flange on a single reaction control system thruster. This delay may impact the final major milestone before NASA deems Boeing's spacecraft ready for routine operations.

    1. As a part of the testing, Boeing will bring the propulsion system up to flight pressurization just as it does prior to launch, and then allow the helium system to vent naturally to validate existing data and strengthen flight rationale.
    2. Mission teams also completed a thorough review of the data from the May 6 launch attempt and are not tracking any other issues.
    3. The teams now are targeting a launch date of no earlier than 4:43 p.m. EDT on Tuesday, May 21, to complete additional testing.

    1. Helium is used in spacecraft thruster systems to allow the thrusters to fire and is not combustible or toxic.
