Nasa's Contingency Plan for Astronaut Return from ISS
NASA has officially announced a contingency plan to safely return astronauts Barry Wilmore and Sunita Williams from the International Space Station (ISS) early next year. During a press conference, officials outlined the specifics of this plan, which comes after unexpected delays with their original return method using the Boeing Starliner spacecraft.
Background of the Boeing Starliner
The Boeing Starliner made its crewed launch on June 5th, after several prior delays and challenges. Initially, Wilmore and Williams were scheduled to spend approximately one week aboard the ISS before making a parachute landing back on Earth. However, complications arose during the docking process, including thruster failures and helium leaks that have contributed to the astronauts remaining in orbit for over two months.
Challenges Faced by Boeing's Starliner
This prolonged stay is directly linked to Boeing's ongoing challenges with the Starliner program, which has faced considerable delays and cost overruns since its conception. Investigations have suggested that deformed Teflon seals might contribute to the failures observed in the Starliner’s thrusters, but NASA's conclusive decision about the safety of the spacecraft will not be made until mid-August.
SpaceX as a Backup Options
If the Starliner is deemed unsafe for a return, NASA intends to utilize their backup plan involving SpaceX’s Crew-9 mission. Despite facing its own launch delays, Crew-9 is set to launch in late September, with two available seats for Wilmore and Williams to return to Earth by February next year.
Impact on Boeing's Reputation
The possibility of needing SpaceX for the astronauts’ return underscores the difficulties Boeing has encountered this year. In addition to the Starliner issues, Boeing faced further scrutiny after an incident involving a door plug explosion on one of its airplanes and a plea of guilty to a criminal fraud charge.
NASA's Preferred Solution
Despite the complications, NASA continues to favor the Starliner for the astronauts' return. However, the necessity of having a reliable and safe backup is paramount, especially given the complexities surrounding space travel and human safety.
Conclusion
As NASA navigates this challenging situation, the agency's ability to adapt its plans reflects its commitment to astronaut safety and mission success. The next updates from NASA regarding the status of the Starliner and the potential return of astronauts Wilmore and Williams are highly anticipated.
