After an extended mission lasting nine and a half months, astronauts Barry “Butch” Wilmore and Sunita Williams, along with fellow crew members, have successfully returned to Earth. Their capsule splashed down off Florida’s Gulf Coast at 5:57 p.m. EDT on Tuesday, following a seventeen-hour journey after undocking from the International Space Station (ISS).
This mission, which began on June 5, saw Wilmore and Williams spend a remarkable 286 days and 7 hours in space. During this period, they completed 4,576 orbits and traveled approximately 121 million miles. Their time aloft places them as the sixth longest mission in NASA’s history.
Wilmore and Williams, donning their SpaceX pressure suits, said their goodbyes to ISS crewmates before entering their Crew Dragon spacecraft for the long-awaited return. Crew 9 commander Nick Hague and Russian cosmonaut Alexander Gorbunov, who launched aboard the Crew 9 mission in September, also came back to Earth at this time, marking their own 171 days in orbit.
The Return Journey to Earth
Upon departing from the ISS at 1:05 a.m. EDT, the astronauts initiated a re-entry sequence involving an automated de-orbit burn at 5:11 p.m. This maneuver reduced their speed in preparation for re-entry into the Earth’s atmosphere.
The Crew Dragon capsule faced intense conditions as it approached the Florida coast, where the heat shield endured temperatures exceeding 2,500 degrees Fahrenheit. After nine minutes in the atmosphere, parachutes deployed, allowing for a safe descent into the Gulf.
A SpaceX recovery ship was on standby to retrieve the capsule, ensuring the crew would receive medical attention shortly after landing. Following initial evaluations, the astronauts were transported to shore and scheduled to fly back to the Johnson Space Center in Houston via NASA jet, where they would be reunited with their families.
Reasons Behind the Extended Stay at the ISS
The mission had originally been anticipated to last only eight days. However, issues with the Starliner spacecraft—including propulsion system helium leaks and thruster complications—led NASA to decide against an immediate return. Instead, Wilmore and Williams remained on board the ISS and were integrated into the Crew 9 rotation, which allowed for a continuous schedule of scientific experiments and research on the station.
NASA had made arrangements for Crew 10 to return home starting last week, involving two new astronauts and a quick handover process. Normally, a five-day transfer period would be standard practice, but this was reduced to ensure safe weather conditions for the splashdown.
The extended stay of Wilmore and Williams generated significant public interest, with some political figures expressing concern over the mission’s length. For example, former President Trump suggested on social media that these astronauts had been “abandoned” in space, a claim that has stirred controversy within the space community.
Although the extended mission raised political discourse, it is essential to note that NASA had previously planned for their return earlier in the year but was delayed by technical issues and readiness for their relief crew.
Comparing Space Stay Records
While the duration of 286 days is substantial, it remains shorter than the U.S. record for the longest continuous mission in space, which stands at 371 days held by astronaut Frank Rubio. Rubio’s extended timeline was due to a separate mission complication involving a coolant leak in the Russian Soyuz spacecraft.
With this mission concluding, Williams will now rank as the second-most experienced U.S. astronaut, having accumulated a total of 608 days in space across her three missions. Wilmore’s total reaches 464 days, showcasing a legacy of contributions to human spaceflight.
