Fluid Science Laboratory concludes its final science activities
- Fluid Science Laboratory ended science operations in July 2026 after 101,000 Earth orbits.
- The Columbus laboratory on the ISS completed 18 experiments and 42,000 operating hours.
- PASTA-3 microgravity emulsion work arrived on Cygnus NG-23 in September 2025.
- Astronauts will assist FSL decommissioning beginning October 9, 2026.
What happened
The Fluid Science Laboratory (FSL) aboard the International Space Station concluded its final science activities in July 2026. The facility remained productive for nearly twice its planned 10-year operating life.
What we know
Launched in February 2008, FSL operated within the station's Columbus laboratory. Its record includes 101,000 orbits around Earth, 18 scientific experiments and 42,000 hours of operation.
Science activities ended in July 2026 after a productive lifetime approaching twice the 10 years originally planned.
PASTA-3 was among the laboratory's last research programmes, examining the formation and evolution of emulsions under microgravity conditions. Its samples reached the station on Cygnus NG-23 in September 2025.
Sophie Adenot assisted with one of FSL's final crew-supported science activities. Léopold Eyharts performed its initial activation and commissioning, while B.USOC coordinated daily science operations for more than a decade.
Why it matters
For readers following the lunar industry, the relevant takeaway is the demonstrated longevity of space research hardware. FSL sustained scientific work well beyond its planned operating life, with continuing operational coordination and astronaut assistance.
What's next
Astronauts are to start assisting with FSL's final decommissioning on October 9, 2026.
