In 1995, Nasa sent 30 fertilised Japanese quail eggs to the Mir space station for 16 days

Image Credit: AI Generated In 1995, a batch of fertilised Japanese quail eggs travelled from Earth to space station ‘Mir’ as part of an experiment designed to answer a question that, ‘can embryos develop normally without the pull of gravity.’ 30 eggs were incubated aboard the station for 16 days before their developing embryos were preserved for examination on Earth. The results were striking. According to Nasa astronaut Shannon Lucid’s account of the mission, abnormalities appeared at more than four times the rate seen in the Earth-based control group. Later scientific records showed that many embryos developed broadly as expected, but some displayed problems affecting their eyes, limbs and beaks. The experiment offered a glimpse into the biological challenges of reproduction and development during long-term spaceflight far beyond Earth.Why did Nasa send fertilised Japanese quail eggs to the Mir space stationThe experiment was part of a wider effort to understand how living things respond to microgravity. As humans began considering longer stays in space, scientists also needed to understand whether the earliest stages of life could continue normally away from Earth. Nasa’s histor...
