Technical issues with Boeing's Starliner capsule have caused NASA to reschedule the planned return of veteran astronauts Butch Wilmore and Suni Williams from the International Space Station. With five helium leaks, maneuvering thruster and propellant valve failures, the return date has been pushed back multiple times. The latest targeted return date is July 6, extending the mission from eight days to a month.
Boeing Starliner Capsule Plagued with Technical Issues, Delaying Astronaut Return
NASA's plans for the return of veteran astronauts Butch Wilmore and Suni Williams from the International Space Station (ISS) have been dealt a blow due to ongoing technical issues with the Boeing Starliner capsule.
The spacecraft, which was launched on May 20th, has experienced a series of setbacks, including five helium leaks, failures in maneuvering thrusters, and problems with propellant valves. As a result, the planned return date has been repeatedly pushed back. The latest targeted return date is now July 6th, extending the mission from eight days to a month.
Background
The Boeing Starliner is a reusable spacecraft designed to transport astronauts and cargo to and from the ISS. It is part of NASA's Commercial Crew Program, which aims to reduce the agency's reliance on Russian spacecraft.
Boeing was awarded a $4.2 billion contract in 2014 to develop and operate the Starliner. However, the program has been plagued by delays and technical challenges. The May 20th launch was already the spacecraft's second attempt to reach the ISS, after a failed flight in 2019 due to software issues.
Technical Issues
The current technical issues with the Starliner capsule are significant and complex. NASA has identified five helium leaks in the propulsion system, which are affecting the spacecraft's ability to maneuver and control its attitude.
In addition, there have been failures in two of the spacecraft's maneuvering thrusters and the propellant valves that supply fuel to the engines. These issues raise concerns about the Starliner's ability to perform critical maneuvers, such as rendezvousing with the ISS and returning to Earth.
NASA's Response
NASA is closely monitoring the situation and working with Boeing to resolve the technical issues. The agency has established a review board to investigate the cause of the problems and develop a plan for corrective actions.
While the delay in the Starliner's return is disappointing, NASA emphasizes the importance of safety and ensuring that the spacecraft is fully operational before bringing the astronauts back to Earth.
