## Expedition 74 Crew Homecoming

NASA will host a public event at Space Center Houston on November 17 to welcome the Expedition 74 crew. Astronauts Jessica Meir, Jack Hathaway, Chris Williams, Sophie Adenot, Sergey Kud-Sverchkov, and Sergei Mikaev will present mission highlights. This gathering serves as a formal conclusion to their extensive scientific work aboard the station.

## Mission Duration and Travel

The crew members completed significant long-duration missions, with Williams, Kud-Sverchkov, and Mikaev spending 241 days in orbit. They traveled over 102 million miles and completed 3,856 Earth orbits. Meanwhile, Meir, Hathaway, and Adenot concluded a 237-day mission, traveling 100 million miles and completing 3,792 orbits before splashing down off Los Angeles.

## Scientific Research Achievements

The team dedicated over 1,400 hours to scientific research and technology demonstrations. Key experiments included metal and tissue 3D-printing to advance in-space manufacturing. They also conducted human health studies, specifically monitoring blood flow and piloting capabilities under changing gravitational conditions, while testing a new compact exercise system for future long-duration spaceflight missions.

## Medical and Quantum Studies

Pharmaceutical research was a major focus, involving protein crystallization for cancer medications and tumor-targeting treatments. The crew also grew stem cells for therapeutic applications. Additionally, they upgraded instruments to study matter and develop quantum technologies, while managing visiting spacecraft and performing essential maintenance to ensure the continued operation of the orbiting laboratory.

## Artemis Program Support

The crew evaluated life-support and environmental systems critical for future exploration under NASA’s Artemis program. These tests are vital for preparing humans for long-duration missions to the Moon and Mars. By refining these technologies, the crew helps overcome the physical and technical challenges associated with sustaining human life during deep space travel.

## Educational Outreach Efforts

Beyond technical operations, the crew engaged global audiences through live educational events and outreach activities. They shared imagery of Earth from orbit, highlighting the importance of scientific discovery and international collaboration. These efforts aim to inspire students and the public by demonstrating the value of continuous human presence in low Earth orbit.

## Historical Context of Station

For over 26 years, humans have lived and worked continuously aboard the International Space Station. This platform enables research breakthroughs that are impossible to achieve under Earth's gravity. The station remains a cornerstone for expanding commercial opportunities and building the foundational knowledge required for the next generation of human space exploration missions.

## Media and Public Engagement

The event at the Johnson Space Center visitor center includes an awards ceremony recognizing key contributors to the mission. Media representatives may request in-person interviews with the astronauts prior to the presentation. This public engagement underscores NASA's commitment to transparency and the dissemination of scientific knowledge gained during complex orbital operations.
