These problems arose during the spacecraft’s journey to the ISS, necessitating a longer mission for astronauts Suni Williams and Butch Wilmore to aid in troubleshooting these issues while in orbit.
Importance of the Service Module
The Starliner’s service module, which encountered most of the issues, is necessary for propulsion and maneuvering.

Engineers will need to gather as much data as possible while the spacecraft remains docked at the ISS, as the service module will be discarded before the capsule returns to Earth, limiting further analysis opportunities.
Previous Delays and Challenges
This crewed test flight follows years of delays and issues identified in uncrewed test missions in 2019 and 2022.

During the 2022 test, similar thruster problems were detected. Despite efforts to address these issues, they resurfaced, indicating a deeper, unresolved problem with the spacecraft’s systems.
Efforts to Resolve Thruster Issues
NASA and Boeing engineers are meticulously reviewing flight data to identify the root cause of the thruster malfunctions.

One theory suggests that overheating during rapid firing sequences might have affected the thrusters’ fuel burn. This ongoing analysis is critical to prevent similar issues in future missions.
Addressing Helium Leaks
In addition to thruster problems, the Starliner experienced helium leaks, further complicating the mission. Engineers are investigating whether these leaks are related to the thruster issues.

Of the five failed service module thrusters, four have been recovered, providing valuable data for troubleshooting.
Ensuring Crew Safety
Steve Stich, NASA’s Commercial Crew Program manager, reassured that the mission’s success and the astronauts’ safe return are not in jeopardy.

He emphasized the importance of a thorough analysis, stating, “We really want to work through the remainder of the data.”
Preparing for Return
If the current timeline holds, Williams and Wilmore are set to undock from the ISS on June 25, with a landing scheduled for early June 26.

However, additional departure opportunities are available, with the next window on July 2 and every four days thereafter, providing flexibility in mission planning.
Importance of In-Orbit Analysis
Conducting in-orbit analysis is important for understanding Starliner’s issues. Since the service module won’t return to Earth, engineers have to capitalize on this time to gather as much data as possible.
