Agnirva Space Premier League - Expedition #30873: Hearts in Space: Studying Cardiac Health with Fruit Flies

Your heart works against gravity every day, pumping blood upward to your brain and downward to your toes. But what happens when gravity is no longer a factor? That’s what the ISS experiment studying cardiac function in the fruit fly, *Drosophila*, aimed to find out. Led by Dr. Rolf Bodmer and NASA Ames Research Center, this investigation explored how microgravity affects heart structure, function, and gene expression.

Fruit flies serve as excellent models for heart studies due to their genetic similarities to humans. This experiment, carried out during Expeditions 51/52, investigated changes in the flies’ heart cells and overall cardiac performance. Researchers were particularly interested in gene activity related to cardiovascular function.

Microgravity causes bodily fluids to shift and organs to adapt. In the case of the heart, this can mean changes in muscle mass, rhythm, and gene regulation. By studying these adaptations in fruit flies, scientists can better predict similar changes in astronauts.

This research is vital for understanding the long-term risks of space travel, including cardiac weakening and rhythm disorders. It also offers new perspectives on heart disease mechanisms that could benefit patients on Earth.

By blending genetics, biology, and space science, the experiment underscores the value of model organisms in tackling complex health challenges in novel environments.
