In 2005, crickets were fertilised in space; larvae hatched earlier than on Earth

In 2005, scientists conducted an unusual experiment aboard the International Space Station (ISS) to investigate how microgravity affects reproduction and early development. According to a NASA technical publication on ISS research, crickets were fertilised in orbit, allowing scientists to observe embryos and larvae that began developing under microgravity. The study examined 112 embryos and first-stage larvae from the spaceflight group, along with ground controls. One of the notable findings was that larvae exposed to microgravity hatched earlier than those developing under normal Earth gravity.Studying development in spaceGravity is an important part of the environment in which life on Earth has evolved. From the movement of fluids through the body to the development of the nervous system, biological processes can be influenced by gravitational forces.
