How astronauts collect blood samples while orbiting the Earth
In short: This video demonstrates how ESA astronaut Tim Peake draws blood for critical research on the International Space Station. Understanding how biological samples are handled in microgravity is essential for studying the physiological changes that occur during spaceflight.
To understand how spaceflight affects the human body, researchers require biological samples taken before, during, and after a mission. On the International Space Station, Tim Peake manages these delicate procedures to support scientific discovery.
Once a sample is collected, it must be processed carefully. The blood tubes are placed in a refrigerated centrifuge and subsequently moved to MELFI, the station's –80°C freezer, to ensure they remain stable for later analysis back on Earth.
