Agnirva Space Premier League - Expedition #30872: How Fruit Flies Help Decode DNA Repair in Space

Understanding how cells repair damaged DNA is crucial, especially when considering the high-radiation environment of space. The Fruit Fly DNA Repair experiment conducted on the International Space Station (ISS) during Expedition 73 tackles this very question. Using fruit flies as a model organism, researchers examined how DNA repair mechanisms function—or fail—in microgravity.

Fruit flies are widely used in genetics because they share many biological pathways with humans and have a short life cycle. This makes them ideal for studying genetic responses in a short timeframe. In the context of spaceflight, where radiation is more intense than on Earth, understanding how cells respond to DNA damage can inform both astronaut health and broader medical science.

On the ISS, these flies were exposed to conditions mimicking space radiation. Scientists monitored their ability to repair DNA damage, particularly focusing on gene expression and repair pathways. Comparing these findings with ground-based controls helps pinpoint the exact effects of space conditions.

The insights gained from this experiment contribute to our understanding of aging, cancer, and other diseases where DNA repair plays a critical role. It also aids in developing countermeasures to protect astronauts during long-duration missions.

This experiment showcases how small organisms can unlock big scientific mysteries, paving the way for safer human spaceflight and improved health technologies on Earth.
