After an uncertain docking process, Boeing still managed to transport its two astronauts to the International Space Station last week. However, the stressful saga of the Starliner continues. The capsule is indeed developing new leaks and NASA is currently evaluating its ability to bring the duo back to Earth.
A mixed success
Last week, Boeing encountered difficulties during the initial docking of the Starliner spacecraft to the ISS. Technical problems delayed the process, requiring rescheduling for another window of opportunity. The spacecraft then experienced failures of five of its thrusters during its initial approach, four of which were successfully recovered. Despite these obstacles, the Starliner ultimately successfully docked with the ISS.
This is obviously a relief for Boeing, which demonstrates that despite initial problems, the Starliner is capable of accomplishing its mission essential tasks. This reaffirms the robustness of the spacecraft design and the skill of the technical teams who worked on the ground to resolve challenges along the way.
For NASA, this success is also crucial, because it shows that its commercial partners can overcome technical difficulties while maintaining high standards of safety and performance. The US space agency relies on missions like this to develop the capacity to transport astronauts and cargo to and from the ISS reliably and regularly. However, not everything is settled yet.
Several leaks from the Starliner
NASA recently reported that Boeing’s Starliner spacecraft encountered a serious technical problem. Five helium leaks have indeed been detected in its service module. Helium is essential in the spacecraft’s propulsion system. It is used to propel propellants without risk of combustion or toxicity. These leaks are therefore considered critical, as they could potentially affect the performance and safety of the Starliner during the remainder of its mission.
Currently, the helium collectors on board the Starliner are closed according to normal procedures to prevent further loss of gas. However, the presence of leaks poses a serious risk, even if they are currently contained. Note that helium is not only used for propellants, but also in other critical systems onboard, highlighting the critical importance of maintaining its integrity.
Boeing and NASA engineers are actively evaluating the potential impact of these leaks on the rest of the mission. They must not only closely monitor current leak rates, but also anticipate any increases that may occur during the remaining duration of the mission. This assessment is critical to determining whether the Starliner can safely complete remaining tasks, including returning astronauts to Earth.
Despite the technical challenges faced by the Starliner, NASA remains confident in Boeing’s ability to resolve the ongoing issues. Mission management teams work closely together to assess risks and determine necessary adjustments to ensure mission success. The next goal is to secure a safe return of the Starliner to Earth scheduled no earlier than June 18, marking a crucial milestone in NASA’s commercial crew program.
