The International Space Station (ISS) is once again operating at full strength following the arrival of four recent astronauts on Saturday, February 14, 2026. The SpaceX Crew-12 mission successfully delivered a team from the United States, France, and Russia to replace crew members who returned to Earth early due to a medical issue, marking NASA’s first such emergency evacuation in 65 years of human spaceflight.
The crew – NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency (ESA) astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev – launched from Cape Canaveral Space Force Station in Florida on Friday, February 13, 2026, aboard a SpaceX Falcon 9 rocket and Dragon spacecraft. The mission is the 12th crew rotation flight with SpaceX as part of NASA’s Commercial Crew Program, according to NASA. The spacecraft autonomously docked with the space station’s Harmony module at approximately 3:15 p.m. Saturday, traveling at 17,000 mph in Earth orbit.
The unexpected return of the previous crew last month left the ISS with a reduced staff of just three astronauts – one American and two Russians – forcing NASA to temporarily suspend spacewalks and scale back research activities. The quick turnaround to launch Crew-12 underscores the importance of maintaining a continuous human presence in low Earth orbit.
Crew-12: A Diverse Team for Long-Duration Research
The incoming crew is slated for an eight to nine-month mission, during which they will conduct scientific research, technology demonstrations, and maintenance perform aboard the orbiting laboratory. Commander Jessica Meir, a marine biologist, is returning to the ISS for her second mission. Notably, during her first visit in 2019, she participated in the first all-female spacewalk, a landmark achievement in space exploration. Cosmonaut Andrey Fedyaev is also a veteran of spaceflight.
For ESA astronaut Sophie Adenot, this mission represents a historic moment as only the second French woman to travel to space. Adenot is a military helicopter pilot. Pilot Jack Hathaway, a captain in the U.S. Navy, is making his first trip to space. He was seen greeting friends and family before launch, as reported by Connecticut Public.
The details surrounding the medical emergency that prompted the early return of the previous crew remain confidential. NASA has cited medical privacy concerns in declining to release the identity of the affected astronaut or specifics about the illness. The astronaut and their three colleagues spent their first night back on Earth at a hospital before returning to Houston. The agency confirmed that preflight medical checks for the Crew-12 astronauts were not altered in light of the previous incident.
Maintaining a Continuous Presence in Orbit
The swift response to restore the ISS to full capacity highlights the collaborative nature of the international space program. The partnership between NASA, SpaceX, ESA, and Roscosmos is crucial for ensuring the continued operation of the orbiting laboratory, which has served as a platform for groundbreaking research and international cooperation for over two decades.
The arrival of Crew-12 allows for the resumption of planned scientific experiments and maintenance tasks, furthering our understanding of the effects of long-duration spaceflight on the human body, developing new technologies for future space exploration, and conducting vital research in areas such as biology, physics, and Earth observation.
Looking ahead, the Crew-12 astronauts will focus on a packed schedule of research and maintenance activities over the coming months. Their work will contribute to NASA’s ongoing efforts to prepare for future missions to the Moon and Mars. The success of this mission is a testament to the resilience and adaptability of the international space community and its commitment to pushing the boundaries of human exploration.
