In 1997, Japanese researchers flew silkworm eggs on STS-84 to study spaceflight effects; developmental abnormalities were more frequent in the flight samples

Silkworm eggs revealed developmental abnormalities in early space experiments. Later, the Rad Silk investigation examined cosmic radiation's long-term effects on the ISS. Ground-based trials showed that radiation during early embryonic development caused higher mutation rates. Visible white spots on larvae indicated radiation exposure levels inside spacecraft. These findings offer insights into radiation's impact on developing organisms beyond Earth.
