Astronauts are subjected to extreme conditions, including weightlessness, high levels of radiation, and extreme temperatures. One of the most significant challenges is managing body temperature as changes in the thermal environment can cause discomfort, fatigue, and even heat-related illnesses. To address this we have developed the LCG¹ that helps astronauts regulate their body temperature.
Design and materials
Around 16 meters of tubes are sewn into a tight fitting garment that covers the entire body except for the feet, hands and head. The LCG is worn underneath the rest of the spacesuit and is made of lightweight, breathable materials that are flexible and comfortable to wear for extended periods. The tubes that circulate the chilled water are made of PVC², a durable and heat-conductive material.
Managing physiological changes
Space travel can affect an astronaut’s cardiovascular system, bone density, and muscle mass. These changes can cause an increase in core body temperature, leading to discomfort and fatigue. By preventing overheating, the LCG reduces the need for astronauts to take frequent breaks to rest and cool down. It also minimizes the risk of heat-related illnesses and allows astronauts to perform at their best during their mission.
