NASA is carefully assessing all available options to ensure the safe return of the crew aboard Boeing’s Starliner spacecraft, which has been docked at the International Space Station (ISS) for eight weeks. The mission, initially planned for a swift return, has encountered technical hurdles that are prompting the space agency to consider alternative solutions for the astronauts’ homecoming.
The Starliner spacecraft, launched aboard an Atlas V rocket in June 2024, was initially expected to return its two crew members, Butch Wilmore and Suni Williams, to Earth within eight days. However, the mission has faced several unexpected technical issues. Notably, the spacecraft experienced helium leaks and complications with its reaction control system thrusters, which are crucial for maneuvering both during departure from the ISS and for executing the essential engine burn required for re-entry.
Recent evaluations have revealed that multiple thrusters essential for Starliner’s return were malfunctioning. This issue is critical as it affects the spacecraft’s ability to steer and perform the necessary re-entry procedures. To address these concerns, ground teams from NASA and Boeing have conducted tests on a thruster system at White Sands, New Mexico, and have also performed in-orbit thruster tests while Starliner remains docked at the ISS. Preliminary results from these tests have been promising, but uncertainties remain.
Given the current technical challenges with Starliner, NASA is now considering alternative plans for the crew’s return. The space agency is exploring the possibility of using a Crew Dragon spacecraft, developed by SpaceX, to bring Wilmore and Williams back to Earth. NASA spokesperson Josh Finch confirmed that there is now a greater than 50-50 chance that the astronauts could return aboard Crew Dragon, depending on the outcome of ongoing evaluations.NASA’s approach reflects a commitment to ensuring the astronauts’ safety and mission success, even if it means shifting from the original plan. The decision will be made with the utmost priority given to the well-being of the crew and the technical feasibility of the return options.
As NASA continues to monitor and assess the situation, the agency remains focused on resolving the technical issues with Starliner while preparing contingencies to utilize Crew Dragon if necessary. The aim is to ensure a safe and timely return for Wilmore and Williams, reflecting NASA’s commitment to the safety and success of its space missions. NASA’s evaluation of both Starliner and Crew Dragon highlights the agency’s proactive approach to addressing unforeseen challenges in space missions. The final decision will be guided by rigorous safety assessments and the goal of returning the astronauts to Earth as safely and efficiently as possible.
