More Setbacks for Boeing’s Starliner
After years of delays and technical issues, Boeing’s Starliner recently docked with the International Space Station (ISS) carrying NASA astronauts Butch Wilmore and Suni Williams. However, the spacecraft’s return to Earth has been postponed due to the discovery of five helium leaks.
Uncertain Return
The precise timeline for Starliner’s undocking and return remains unclear. Boeing has identified five helium leaks, a critical component for the spacecraft’s thruster systems, which are essential for maneuvering in space. While NASA has extended Wilmore and Williams’ stay on the ISS from June 14 to no earlier than June 18, the specific impact of the leaks on the delay is yet to be determined.
Ongoing Challenges
Boeing’s Starliner has faced numerous obstacles since its inception, including multiple delays, technical malfunctions, and a failed uncrewed test flight in 2019. Despite docking with the ISS, the mission won’t be deemed successful until the astronauts return safely to Earth.
Leak Discovery and Impact
The first helium leak was discovered last month but was deemed not severe enough to delay the ISS mission. However, additional leaks were detected en route and during docking procedures. Engineers have ensured that the capsule retains sufficient helium for its return, approximately ten times the required amount for space maneuvering. While docked, the helium manifolds are closed to prevent further loss.
Making the Most of the Situation
NASA is utilizing the extended mission time effectively. ISS officials tweeted that the additional days will allow the crew to perform a spacewalk on June 13 while engineers complete the necessary system checks on Starliner.
