The scheduled launch of the Crew-10 mission, a collaborative effort between SpaceX and NASA to send four astronauts to the International Space Station (ISS), was canceled on Wednesday evening, March 12, due to a hydraulic issue in a ground support system. The Falcon 9 rocket, set to lift off from the Kennedy Space Center in Florida at 7:48 p.m. EDT, aimed to kick off the long-awaited return of American astronauts Butch Wilmore and Suni Williams, stranded on the ISS for over nine months. Authorities announced the postponement during a live broadcast, shifting the next launch window to Thursday at 7:25 p.m. EDT. This delay, though temporary, underscores the technical complexities and safety priorities that define modern space missions, keeping the fate of the stranded astronauts in limbo for at least another day.
Originally planned as a critical step to relieve the Crew-9 team and bring Wilmore and Williams back to Earth, the Crew-10 mission involves a diverse team led by commander Anne McClain, alongside pilot Nichole Ayers, Japan’s Takuya Onishi, and Russia’s Kirill Peskov. The cancellation halted preparations just hours after U.S. Defense Secretary Pete Hegseth shared a supportive message on X, wishing the crew luck and highlighting the prominent role of American military personnel in the operation. With the rescheduling, NASA and SpaceX now face the challenge of aligning weather conditions and technical fixes to ensure a successful launch, a task made more urgent by the prolonged ordeal of the astronauts awaiting rescue.
Hegseth’s message emphasized the involvement of the U.S. military, noting that active-duty officers McClain, from the Army, and Ayers, from the Air Force, join retired Navy captains Wilmore and Williams in this high-stakes mission. His words, delivered in a video posted online, aimed to boost morale ahead of what was supposed to be a Wednesday night launch, now deferred. The delay adds another layer of anticipation to a mission already marked by logistical hurdles and public attention, fueled by comments from President Donald Trump and SpaceX CEO Elon Musk about the urgency of bringing the stranded astronauts home.
Technical setbacks disrupt mission timeline
Wednesday’s aborted launch stemmed from a last-minute detection of a hydraulic fault in a ground-based system critical for stabilizing the Falcon 9 rocket before liftoff. Engineers identified the issue less than an hour before the planned departure, prompting SpaceX and NASA teams to scrub the attempt rather than risk compromising the mission’s safety. The decision reflects a cautious approach honed by years of experience in spaceflight, where precision outweighs haste. Teams are now working to diagnose and resolve the problem, targeting Thursday’s launch window, though favorable weather and system reliability remain key variables.
The Crew-10 team, already suited up and positioned inside the Dragon capsule atop the rocket, had to stand down and await further instructions. Anne McClain, a seasoned astronaut with prior ISS experience, commands the mission, supported by Nichole Ayers, making her spaceflight debut. Takuya Onishi, representing Japan’s space agency JAXA, and Kirill Peskov, from Russia’s Roscosmos, round out the quartet tasked with a six-month stint on the ISS. Their arrival will facilitate a handover period with the Crew-9 team, allowing Wilmore, Williams, Nick Hague, and Aleksandr Gorbunov to return aboard the Dragon Freedom capsule, currently docked at the station.
This setback echoes broader challenges in recent space endeavors. The Boeing Starliner, which carried Wilmore and Williams to the ISS in June last year, encountered helium leaks and thruster malfunctions that deemed it unfit for their return. After months of deliberation, NASA opted to bring the duo back via SpaceX’s Dragon, a decision that extended their stay and spotlighted the contrasting reliability of the two companies’ spacecraft. The Starliner landed uncrewed in New Mexico on September 6, leaving the astronauts to adapt to an unexpected nine-month mission.
Nine months stranded in orbit
Butch Wilmore and Suni Williams, both veteran NASA astronauts and former Navy captains, launched aboard the Boeing Starliner on June 5 last year for what was meant to be an eight-day test flight. Their arrival at the ISS marked the spacecraft’s first crewed mission, a milestone for Boeing’s Commercial Crew Program. However, technical issues surfaced soon after docking, with helium leaks and thruster failures raising concerns about the Starliner’s ability to safely return them to Earth. What began as a brief visit morphed into an extended stay, testing their resilience and NASA’s contingency planning.
By August, NASA concluded that the Starliner posed too great a risk for reentry, opting instead to integrate Wilmore and Williams into the ISS’s Expedition 71 alongside the Crew-9 team. The uncrewed Starliner departed the station in September, landing in the White Sands Missile Range, while the astronauts continued their work in orbit. Over the past nine months, they’ve conducted scientific experiments, maintained station systems, and adjusted to life in microgravity far longer than anticipated, contributing valuable data to NASA’s research efforts.
Public interest in their plight intensified as months passed. President Trump criticized the previous administration for allegedly abandoning them, delivering a heartfelt message last week promising their swift return. In an interview with Fox Business, Elon Musk affirmed SpaceX’s commitment to the rescue, stating, “We’re going to bring them back.” The Crew-10 mission, now delayed, represents the culmination of these efforts, with its success hinging on Thursday’s launch attempt.
Updated timeline for the astronauts’ return
The postponement of Crew-10 has shifted the schedule for Wilmore and Williams’ homecoming. Assuming Thursday’s launch proceeds as planned, the Dragon capsule will reach the ISS within 24 to 36 hours, initiating a brief handover with the Crew-9 team. The current plan projects the Crew-9’s departure, carrying Wilmore, Williams, Hague, and Gorbunov, as early as March 16. Here’s the adjusted timeline:
- March 12: Original launch attempt for Crew-10, canceled due to hydraulic issues.
- March 13: Next launch window at 7:25 p.m. EDT from Kennedy Space Center.
- March 15-16: Expected docking of Crew-10 at the ISS, followed by a handover period.
- March 16: Anticipated return of Crew-9 to Earth, landing off Florida’s coast.
This schedule remains contingent on weather conditions at the splashdown site and the absence of further technical glitches. The Crew-9’s Dragon Freedom capsule, docked since September, will carry the four astronauts back, concluding a mission that has spanned nearly a year for Wilmore and Williams.
U.S. military shines in space collaboration
Defense Secretary Pete Hegseth spotlighted the military’s significant presence in the Crew-10 mission, praising the contributions of active-duty and retired personnel. Anne McClain, an Army colonel, leads the team, while Nichole Ayers, an Air Force major, serves as pilot. Butch Wilmore and Suni Williams, retired Navy captains, embody the service’s legacy as they prepare to return. Hegseth described the mission as a proud moment for the Army, Air Force, and Navy, uniting their expertise in a joint effort with NASA and SpaceX.
This military involvement underscores a longstanding partnership between the Department of Defense and NASA, blending operational discipline with scientific exploration. Hegseth’s remarks, shared hours before the scrubbed launch, aimed to rally support for the crew, though the delay has pushed this symbolic night to Thursday.
Crew-10’s diverse team and mission goals
The Crew-10 mission unites a multinational team with distinct objectives for their six-month tenure on the ISS. Anne McClain, who logged 204 days in space during Expedition 58/59, brings leadership experience, while Nichole Ayers debuts as a skilled test pilot. Takuya Onishi, with a prior 115-day mission in 2016, represents JAXA, and Kirill Peskov adds Roscosmos’ perspective to the collaboration. Their tasks include conducting experiments, upgrading station infrastructure, and preparing for future lunar and Mars missions under NASA’s Artemis program.
Key mission highlights include:
- Over 200 scientific experiments, ranging from biological studies to materials testing.
- Maintenance of ISS systems, ensuring operational continuity.
- Collaboration with international partners to advance space exploration goals.
Their arrival will mark the 10th crew rotation facilitated by SpaceX, reinforcing the company’s pivotal role in NASA’s crewed missions since 2020.
