Boeing’s Starliner Capsule “Calypso” Extends Stay at ISS for Further Testing

NASA announced an extension to Boeing’s Starliner capsule mission at the International Space Station, doubling the time Calypso will remain docked with the ISS. Originally planned for a nine-day mission, the developmental nature of the mission, known as Boeing’s crew flight test, has led to an extension for further testing on the spacecraft. With crew members Butch Wilmore and Suni Williams set to return to Earth next week, the Starliner’s mission will now last at least 17 days, showcasing the collaboration between Boeing and NASA in conducting vital tests while the capsule is docked at the ISS.

The prolonged mission allows for a series of tests to be carried out on the Starliner capsule, including operating the hatch, firing thrusters, and checking the cabin air temperature. These tests are crucial in ensuring the safety and functionality of the spacecraft as it prepares for crewed missions. Additionally, SpaceX has successfully made 12 crewed trips to the ISS over the past four years, putting pressure on Boeing to address any setbacks or delays in their mission.

Despite the successful launch and docking of the Starliner capsule, the mission has encountered several challenges. Initially, a single leak in the helium propulsion system was identified, but it was determined to be stable and not a safety concern. However, since docking, four additional helium leaks have been discovered, posing a potential risk to the mission. The spacecraft has also experienced issues with its propulsion system, with five of the 28 thrusters not operating as intended. Troubleshooting efforts have recovered some of the malfunctioning thrusters, but further testing is required before the spacecraft can undock from the ISS.

The crew flight test represents a critical step towards NASA certifying Boeing to conduct operational, six-month missions with crew members. Despite the setbacks faced by the Starliner mission, Boeing remains optimistic about the remaining time on station and the margin for completing the necessary tests. With SpaceX leading the way in crewed trips to the ISS, Boeing is under pressure to address the challenges and delays to catch up with their competitor.

The extension of the Starliner capsule mission at the ISS highlights the complexities and challenges of space exploration. As Boeing and NASA work together to conduct essential tests and overcome setbacks, the focus remains on ensuring the safety and success of future crewed missions to the International Space Station.
