With just over three weeks to go until he returns to Earth, ESA astronaut André Kuipers is still busy with science on the International Space Station, as well as maintenance and routine operations.

André writes: In the past weeks I have been doing many ‘life science’ experiments investigating human behaviour in weightlessness. I worked with the Fluid Science Laboratory examining liquids in space. I also conducted maintenance work and small repairs. Just like a laboratory on Earth, maintenance and repair is important to keep everything running smoothly. Some experiments on the Station run autonomously.
