Agnirva Space Premier League - Expedition #32346: Tracking Human Fluids in Microgravity: The Early Sprut-MBI Study

How does the human body manage its fluids in space? To answer this, the Sprut-MBI experiment was launched during early ISS expeditions. Led by V. Noskov from the Institute for Biomedical Problems, the study focused on understanding how bodily fluids redistribute without gravity’s pull.

Normally, gravity helps move blood and other fluids throughout our bodies. In space, fluids float upward, causing swelling in the face and head, and potentially affecting vision and brain pressure. Sprut-MBI used sensors and body composition monitors to track these changes across different spaceflights.

This foundational research set the stage for later experiments like Sprut-2. It was crucial for identifying early signs of fluid imbalance and developing ways to protect astronaut health. The results also influenced terrestrial medicine, offering insights for managing edema and circulatory problems in bedridden patients.
