The National Aeronautics and Space Administration (NASA) is approaching a critical deadline to determine the return route for two astronauts currently aboard the International Space Station (ISS). By the end of August, NASA must decide whether to bring them back to Earth using Boeing’s Starliner spacecraft or opt for SpaceX’s Crew Dragon capsule, officials announced on Wednesday.
NASA astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams launched to the ISS on June 5 aboard the Starliner for what was intended to be an eight-day mission. However, their return has been postponed due to thruster malfunctions identified during the Starliner’s first crewed mission to the ISS.
“We’re reaching a point where that last week in August, we really should be making a call, if not sooner,” said Ken Bowersox, associate administrator of NASA’s Space Operations Mission Directorate, during a press conference. He added that while the astronauts are making the best of their extended stay, they are eager for a decision.
The primary concern revolves around the Starliner’s propulsion system, particularly the thrusters critical for a successful deorbit burn. Bowersox emphasized that Boeing is fully committed to resolving the issues: “There have been very honest discussions with Boeing, and they are 100 percent behind their vehicle.”
If NASA opts against using the Starliner, SpaceX could adjust its upcoming Crew-9 mission, potentially scheduling a launch on September 24 with two astronauts instead of four. This would allow Wilmore and Williams to return to Earth aboard the Crew Dragon capsule in February 2025, although this shift could represent a significant setback for Boeing.
NASA’s chief astronaut, Joe Acaba, noted that both Wilmore and Williams were aware that, as a test flight, the mission “might not be perfect.” He affirmed their professionalism and readiness: “Human space flight is inherently risky, and as astronauts, we accept that as part of the job. They’re prepared for this and they’re doing great.”
Despite the challenges, Bowersox mentioned that in an emergency, the Starliner could still be used to bring the astronauts home, as the risk is considered reasonable for a contingency scenario.
Boeing vs. SpaceX
Boeing and SpaceX have been competitors since both were awarded multibillion-dollar contracts in 2014 to transport NASA astronauts to the ISS, following the retirement of the Space Shuttle program in 2011. SpaceX successfully conducted its first crewed mission in 2020 and has since carried dozens of astronauts, while Boeing has faced delays and technical issues.
The outcome of NASA’s upcoming decision could have significant implications for the commercial spaceflight industry, astronaut safety, and the ongoing operations aboard the ISS.
