NASA, Boeing Target Early 2026 for Next Starliner Flight After Propulsion Fault

/in /tarafından

NASA announced on Thursday that it is working with Boeing to test and certify the CST-100 Starliner for its next crewed mission, which could take place as early as late 2025 or early 2026. The update comes after the spacecraft’s troubled debut crewed flight to the International Space Station (ISS), which was significantly extended due to a propulsion system malfunction.

The mission, originally planned as an eight-day trip, ended up keeping astronauts Butch Wilmore and Suni Williams in orbit for over nine months. They returned earlier this month aboard a SpaceX Dragon capsule.

Testing and Analysis Underway
NASA and Boeing are now planning a series of propulsion system tests and engineering analyses scheduled to run through the spring and summer. The goal is to resolve the issues that plagued Starliner’s propulsion system and ensure the spacecraft meets safety requirements for future flights.

Steve Stich, manager of NASA’s Commercial Crew Program, said the timeline for the next flight “is likely to be in the timeframe of late this calendar year or early next year.”

Cost and Development Hurdles
Boeing’s Starliner project has been fraught with delays and technical issues since its inception. The effort has cost Boeing over $2 billion to date, placing it under increased scrutiny, especially in contrast to competitor SpaceX, whose Dragon capsule has become the preferred vehicle for crew transport to the ISS.

The faulty propulsion system on Starliner has become a critical focal point for NASA’s certification process, as the agency continues to rely on multiple commercial providers for its low-Earth orbit missions.

What’s Next
NASA emphasized that it will not proceed with another Starliner crewed launch until the spacecraft passes all necessary tests. Both agencies remain committed to restoring confidence in the system, aiming to bring Starliner into regular rotation for ISS crew missions.

NASA-SpaceX Capsule Switch Poised to Bring Starliner Astronauts Home Days Sooner

/in /tarafından

NASA announced on Tuesday that it has swapped out the astronaut capsule initially planned for a routine flight to the International Space Station (ISS), a move that will expedite the return of two astronauts who have been aboard the station for longer than expected. The U.S. space agency decided to use a previously flown SpaceX Crew Dragon capsule, Endeavor, for its Crew-10 mission, replacing a new capsule whose production was delayed.

This change will bring the Crew-10 launch forward to March 12, moving up from the original March 25 date. NASA will still need to conduct a flight readiness assessment of the Endeavor capsule, which has already completed three previous missions.

The change in capsule is linked to the return of astronauts Butch Wilmore and Suni Williams, who have been on the ISS since last summer aboard Boeing’s Starliner capsule, which faced technical issues. Their return was contingent on the arrival of the Crew-10 crew to maintain the station’s normal staffing levels.

This shift in the launch schedule comes after a recent intervention by former President Donald Trump, who urged SpaceX CEO Elon Musk to bring Wilmore and Williams back “as soon as possible.” Trump had criticized President Joe Biden’s administration over the astronauts’ extended mission, despite Biden’s lack of involvement. Musk accepted Trump’s request and echoed similar sentiments, though the mission’s delays were largely attributed to Boeing’s engineering challenges.

While NASA’s statement did not specifically mention the intent to accelerate the return of Wilmore and Williams, the capsule swap will indeed bring them back earlier than initially planned. NASA’s Commercial Crew Program head, Steve Stich, acknowledged SpaceX’s flexibility in handling the unexpected changes.

The decision to switch capsules has also affected other planned SpaceX missions, including the Fram2 private astronaut mission and Axiom’s planned Crew Dragon flight for astronauts from India, Poland, and Hungary. The shift means that SpaceX will have to adjust its planned capsule allocations, impacting these missions.

SpaceX’s Crew Dragon capsule was developed with around $3 billion in funding from NASA’s Commercial Crew Program, which aims to develop private-sector capabilities for spaceflight, reducing costs and increasing competition. In contrast, Boeing’s Starliner capsule, which has struggled with engineering setbacks, is also part of the same program but has faced more significant challenges.

Crew-9 Astronauts Arrive at ISS Amid SpaceX Rocket Anomaly

/in /tarafından

The SpaceX Crew-9 mission successfully docked at the International Space Station (ISS) on Sunday, despite SpaceX reporting an anomaly with the Falcon 9 rocket. NASA astronauts Nick Hague and Russian cosmonaut Aleksandr Gorbunov arrived safely, joining the current ISS crew after launching from Cape Canaveral the previous day. The capsule’s hatch was opened at 7:04 p.m. ET, marking the official arrival of the Crew-9 team.

The mission’s arrival at the ISS came after SpaceX disclosed that the second stage of the Falcon 9 rocket experienced an off-nominal deorbit burn, resulting in its disposal in the ocean, though it missed the targeted area. SpaceX has paused future Falcon 9 flights pending further investigation into the root cause of the issue.

NASA astronauts Suni Williams and Butch Wilmore, who had been on the ISS since June after issues with their Boeing Starliner spacecraft, will return to Earth with Crew-9 next year. Due to technical issues with the Starliner, NASA decided to extend their stay and use SpaceX’s Crew Dragon for their return. The Starliner returned to Earth unmanned in September following complications with helium leaks and thruster malfunctions.

Williams and Wilmore had originally planned for a short stay on the ISS, but NASA adjusted its plans, extending their mission. They will now fulfill duties alongside the Crew-9 team until their scheduled return in early 2024. NASA cited vehicle availability and ISS operational needs as key reasons for keeping the astronauts in space for a full crew rotation.

The full ISS crew now consists of NASA’s Don Pettit, Russian cosmonauts Aleksey Ovchinin, Ivan Vagner, Williams, Wilmore, Hague, and Gorbunov. NASA and Russia’s Roscosmos have continued their collaborative seat-swapping program, which brought Pettit and Gorbunov to the station on spacecraft from each other’s countries.

SpaceX’s next mission, Crew-10, is slated for February 2024 and will involve a newly developed Crew Dragon capsule. Until then, Williams and Wilmore will remain in space, having adapted to the extended mission duration.
