ISS cricket experiment found microgravity-exposed larvae hatched earlier than ground controls

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. Studying organisms in microgravity allows scientists to separate some of these effects and examine how living systems respond when the usual pull of gravity is greatly reduced.The cricket experiment, known as Crickets in Space-2, or CRISP-2, built on earlier research conducted during NASA's N...
