NASA is considering extending the mission duration for Boeing’s Starliner spacecraft. Initially planned for 45 days, the mission may now last up to 90 days, according to Steve Stich, NASA’s Commercial Crew Program manager.
Initial Mission and Current Situation
The first crewed test flight of the Starliner, carrying astronauts Sunita ‘Suni’ Williams and Butch Wilmore, has faced some issues. These include helium leaks and thruster outages during its journey to the International Space Station (ISS). As a result, NASA has not set a firm return date for the spacecraft.
Potential Mission Extension
NASA is looking into extending the mission to 90 days. This decision is partly because of the need to conduct ground tests in New Mexico. These tests aim to understand the thruster problems that occurred earlier. Stich emphasized that NASA is not in a rush to bring the astronauts back home. The timeline for the return will depend on the results of these tests.
Thruster Issues and Ground Tests
Boeing and NASA are conducting tests to figure out why some of the Starliner’s thrusters failed. Mark Nappi, Boeing’s vice president and program manager for the Commercial Crew Program, stated that the tests in New Mexico might provide the answers needed. If further tests in space are required, the Starliner will remain docked with the ISS.
Integration with ISS Crew
Meanwhile, Williams and Wilmore are with the ISS crew and are performing routine tasks. They have adjusted well to their extended stay.
Technical Challenges
The Starliner faced several technical challenges, including multiple helium leaks and thruster issues. The service module of the Starliner, which provides power during the flight, had several problems. This module will not survive re-entry to Earth as it is designed to be jettisoned and destroyed.
Future Decisions
It is still uncertain whether NASA will officially extend the mission to 90 days. NASA officials need to verify the battery life of the Starliner for the extended duration. While the batteries are being recharged at the ISS, they must operate effectively for 90 days, just as they would for 45 days.
Comparison with SpaceX
Boeing has faced significant challenges with the Starliner program, especially when compared to SpaceX’s Crew Dragon. The spaceflight industry often experiences delays and cost overruns, but Boeing’s difficulties have been particularly notable.
So, NASA is carefully considering all factors before deciding on the extended mission duration for the Starliner. The focus remains on ensuring the safety and success of the mission for astronauts Sunita Williams and Butch Wilmore.
