NASA Hosts Expedition 74 Crew Homecoming at Space Center Houston
Astronauts share mission highlights following their return from long-duration space station research.
1Expedition 74 Mission Conclusion
NASA will host a public event on November 17 at Space Center Houston to welcome home the Expedition 74 crew. Astronauts Jessica Meir, Jack Hathaway, Chris Williams, Sophie Adenot, and cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev will present mission highlights. This event follows their successful long-duration stay aboard the International Space Station.
2Launch and Return Logistics
The crew members arrived at the station via different missions throughout 2025 and 2026. Williams, Kud-Sverchkov, and Mikaev launched from Kazakhstan on November 27, 2025, returning after 241 days. Meir, Hathaway, and Adenot launched from Florida on February 13, 2026, completing a 237-day mission before splashing down in the Pacific Ocean off Los Angeles.
3Scientific Research Achievements
The crew dedicated over 1,400 hours to scientific research and technology demonstrations. Key activities included testing metal and tissue 3D-printing technologies to advance in-space manufacturing. They also conducted human health studies, specifically monitoring blood flow and piloting capabilities under changing gravitational conditions to better understand the physiological effects of long-duration spaceflight.
4Medical and Pharmaceutical Studies
Research efforts extended into pharmaceutical development, focusing on protein crystallization for cancer medications and tumor targeting treatments. The team also grew stem cells for potential therapeutics. These experiments utilize the unique microgravity environment of the orbiting laboratory to achieve results that are currently impossible to replicate within Earth-based laboratory settings.
5Artemis Program Support
The crew evaluated life-support and environmental systems essential for future deep-space exploration under NASA’s Artemis program. They also activated a new compact exercise system and performed critical maintenance on the station. These operational tasks ensure the continued viability of the orbiting laboratory while preparing for future missions to the Moon and Mars.
6Educational Outreach Efforts
Beyond technical research, the Expedition 74 crew engaged global audiences through live educational events and public outreach. They shared high-resolution imagery of Earth to highlight the importance of scientific discovery and international collaboration. These initiatives aim to inspire students and demonstrate the value of continuous human presence in low Earth orbit.
7Station Operational History
For over 26 years, humans have lived and worked continuously aboard the International Space Station. This ongoing presence allows for breakthroughs in quantum technologies and material science. The station serves as a vital testbed for NASA, helping researchers overcome the complex challenges of human spaceflight while expanding commercial opportunities in orbit.
8Media and Public Engagement
The homecoming event at the Johnson Space Center visitor center includes an awards ceremony for key mission contributors. Media representatives may request interviews with the astronauts before the 6 p.m. presentation. This gathering serves as a formal conclusion to the mission, recognizing the collective efforts of international space agencies involved.
