NASA and Boeing Co.
Both teams are working to resolve technical issues encountered during flight while gearing up for additional propulsion system evaluations in the near future.
After the uncrewed Starliner safely returned from orbit, thorough postflight analysis has been carried out, resolving over 70% of identified issues.
Meanwhile, propulsion system anomalies experienced during the mission will remain under examination through at least 2025 as further testing progresses.
Both NASA and Boeing are working to determine the necessary scope and timeline for upcoming propulsion system evaluations, which are scheduled throughout the spring and summer.
Key tests at the White Sands Test Facility in New Mexico will include integrated thruster firings within a single service module "doghouse" to refine thermal models and assess potential upgrades to propulsion and spacecraft heat shielding.
To enhance performance in upcoming missions, engineers are evaluating operational adjustments, including modifying thruster pulse sequences to control heat accumulation and integrating thermal barriers within the propulsion unit.
"Our investment in commercial crew transportation capabilities is providing the needed flexibility to operate in space as safely as possible and respond to changes quickly when they arise. NASA is seeing the commitment from Boeing to adding the Starliner system to the nation's crew transportation base," said Ken Bowersox, associate administrator for Space Operations at NASA Headquarters in Washington.
Additionally, teams are testing updated helium system seals to reduce the risk of leaks. Mission planners intend for Starliner's next flight to be a fully operational post-certification mission, carrying crew members to the space station.
NASA retains the flexibility to utilize the spacecraft for cargo-only missions if required.
The Starliner program has faced numerous setbacks, including delays, technical malfunctions, and significant budget overruns.
Intended to serve as NASA's alternative crew transport to the International Space Station alongside SpaceX's Crew Dragon, the spacecraft has encountered persistent challenges. Since its first crewed test flight in June, Starliner has dealt with thruster failures, helium leaks, and other critical complications.
Price Action: BA shares traded lower by 2.10% at $175.35 at last check Friday.
