Agnirva Space Premier League - Expedition #31540: Exploring Life’s First Steps: Artemia Eggs Hatch in Microgravity

What happens when life begins in space? That’s what students at Darca Bat Yam High School set out to discover with their fascinating experiment aboard the ISS. They studied the emergence—or hatching—of Artemia eggs (also known as brine shrimp) in the microgravity environment of space.

Artemia are ideal candidates for such a study because they can remain dormant for long periods and hatch when conditions are favorable. By sending these eggs into orbit and observing how they developed compared to Earth-based control groups, students learned how microgravity influences biological processes, especially early development stages.

The project combined biology, physics, and space science to answer big questions about how life adapts to new environments. This experiment also helped inform future studies related to space farming, life support systems, and possibly even human reproduction in space. Plus, it empowered high schoolers with the opportunity to participate in authentic space research—a rare and invaluable experience.
