Boeing’s Starliner capsule “Calypso” has encountered unexpected challenges during its mission at the International Space Station (ISS). Originally planned for a nine-day mission, the Starliner crew flight test has been extended to at least 17 days. This extension is attributed to the need for further spacecraft testing while docked with the ISS. The crew, consisting of Butch Wilmore and Suni Williams, is now expected to return to Earth on June 22, departing from the ISS at 11:42 p.m. ET on June 21 and landing approximately six and half hours later at 6:26 a.m. ET.
During the extended mission, Boeing and NASA are conducting a series of tests on Starliner to ensure its safety and functionality. Some of the tests include operating the capsule’s hatch, firing seven thrusters, and checking the cabin air temperature. Additionally, the crew will repeat some “safe haven” testing, which involves using the spacecraft as a shelter during emergencies. While the specific reasons for the additional testing were not provided, NASA has assured that the spacecraft remains cleared for crew emergency return scenarios within the flight rules.
Despite the mission progressing as planned, Starliner encountered technical issues both before and after docking with the ISS. Prior to launch, a leak in the helium propulsion system was identified but deemed stable and non-threatening. However, four additional helium leaks were discovered since docking, prompting concerns about the spacecraft’s safety. In addition to the helium leaks, an issue with the spacecraft’s propulsion system arose during docking, with five out of 28 thrusters not operating as expected. While troubleshooting helped recover four of the malfunctioning thrusters, Boeing and NASA are continuing to monitor the situation closely.
Boeing’s Starliner was initially seen as a competitor to SpaceX’s Dragon in crewed missions to the ISS. However, repeated setbacks and delays have shifted Starliner into a backup position for NASA. SpaceX’s Dragon has successfully completed 12 crewed trips to the ISS in the past four years, while Starliner has faced challenges in meeting the agency’s expectations. As a result, NASA is planning to have SpaceX and Boeing alternate in flying astronauts to the ISS in the future.
Boeing’s Starliner capsule “Calypso” has encountered unforeseen challenges and setbacks during its mission at the International Space Station. Despite the extension of the mission for further testing, Boeing and NASA are working together to address technical issues and ensure the safety of the spacecraft and its crew. As the space exploration industry continues to evolve, overcoming obstacles and learning from setbacks will be crucial for the success of future missions.
