SpaceX Crew-8 Departs ISS After Weather Delays, Prepares for Splashdown

SpaceX’s Crew-8 mission has undocked from the International Space Station (ISS), heading for a scheduled splashdown on October 25, 2024, after delays caused by Hurricane Milton. The mission, which included six months of scientific research aboard the ISS, is the latest in NASA’s Commercial Crew Program, demonstrating the growing importance of private space companies like SpaceX in ensuring the future of human space exploration.

SpaceX’s Crew-8 mission, carrying four astronauts, has undocked from the International Space Station (ISS), after facing delays due to weather-related challenges.

The Dragon Endeavour spacecraft separated from the station on October 23, 2024, at 5:05 p.m. EDT, marking the beginning of the crew’s return to Earth after more than six months in orbit. The mission is now on track for a scheduled splashdown off the coast of Florida on October 25, concluding a successful long-duration stay in space.

The Journey Home: Crew-8's Delayed Departure

Originally slated to depart in early October, Crew-8's return was postponed multiple times due to the adverse weather conditions brought by Hurricane Milton, which impacted Florida's eastern coastline earlier this month. NASA had to delay the mission’s undocking several times, with officials prioritizing astronaut safety, given that splashdown zones in the Atlantic were deemed hazardous for recovery operations. NASA stated that the delay was necessary due to “poor conditions in the splashdown area during and in the wake of Hurricane Milton,” which made it unsafe for recovery teams to operate in the region.

Despite the setbacks, the Crew-8 astronautsNASA’s Matthew Dominick, Michael Barratt, Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin—remained in good spirits. The spacecraft finally undocked while the ISS was orbiting 260 miles above the Pacific Ocean, commencing the final leg of their mission. The crew's safe return is now expected early on October 25, with the splashdown scheduled for approximately 3:30 a.m. EDT off the Florida coast. NASA will provide live coverage of the event, including a post-splashdown news conference later that morning.

Mission Achievements and Life Aboard the ISS

The Crew-8 mission, launched in March 2024, has been part of NASA’s ongoing efforts to maintain a continuous human presence in low-Earth orbit. The team conducted a wide array of scientific experiments during their six-month stay aboard the ISS, contributing to studies on microgravity's effects on the human body, the behavior of materials in space, and advancements in technology that could benefit future deep-space missions. Notably, NASA astronaut Jeanette Epps conducted important research on radio frequency identification hardware, while Michael Barratt performed experiments using a fluorescence microscope to observe the behavior of particles in microgravity.

Reflecting on the mission, NASA praised the astronauts for their resilience and adaptability, particularly as they dealt with unexpected delays in their return. The Crew-8 astronauts have remained integral to daily ISS operations, performing maintenance tasks and participating in numerous research projects. Matthew Dominick, the mission commander, also led several spacewalks during their tenure on the station, contributing to ongoing upgrades of the ISS’s external systems.

Looking Forward: SpaceX and NASA’s Future Plans

With Crew-8 nearing the end of its journey, attention is turning to the Crew-9 astronauts, who arrived at the ISS on September 29, 2024, aboard another SpaceX Crew Dragon capsule. This transition is part of NASA's ongoing long-duration crew rotation program, designed to ensure continuous scientific research and technological advancements aboard the ISS. Crew-9, which includes NASA’s Nick Hague and Roscosmos’ Aleksandr Gorbunov, will remain aboard the station for another six months, conducting experiments similar to those performed by Crew-8.

In the meantime, NASA and SpaceX are preparing for the launch of Crew-10, which is scheduled no earlier than February 25, 2025. This upcoming mission will continue NASA’s human spaceflight efforts, with astronauts Anne McClain and Nichole Ayers among those assigned to the crew. NASA’s reliance on SpaceX for crew transportation to the ISS has become increasingly important as the agency plans for ambitious goals, including future missions to the Moon and Mars.

However, Boeing’s Starliner spacecraft—another vehicle meant to transport NASA astronauts to the ISS—remains under review following technical issues discovered during its test missions earlier in 2024. NASA had originally planned to use Starliner for some of its upcoming crewed missions, but propulsion problems forced the agency to delay its use. This has left SpaceX as the primary commercial partner for NASA’s Commercial Crew Program.

The Importance of Crew-8's Mission and Broader Spaceflight Goals

As Crew-8 prepares for splashdown, their successful mission underscores the growing collaboration between NASA and private space companies like SpaceX, which are playing an increasingly vital role in ensuring the success of human space exploration. The mission’s extended duration due to weather delays has demonstrated the resilience and flexibility of both the astronauts and the mission team. As Crew-8 mission commander Matthew Dominick noted during an update, “Spaceflight is complex, and we always need to be prepared for the unexpected.”

The safe return of Crew-8 will mark another milestone in NASA’s Commercial Crew Program, which continues to open new frontiers for human space exploration. With Crew-10 on the horizon and the potential for further development of the Boeing Starliner, NASA’s focus remains on ensuring the sustainability of human spaceflight well into the future.
