As we explore the vastness of space, keeping astronauts safe and comfortable becomes a top priority. One critical aspect of astronaut safety is regulating their body temperature in the extreme conditions of space, where temperatures can range from freezing to scorching. To tackle this challenge, our research and development team has been developing a LCG¹.
The LCG is a form-fitting garment that astronauts wear next to their skin, which is embedded with tiny tubes or channels that circulate chilled water. These tubes are strategically placed to cover the areas of the body that generate the most heat, such as the chest, back, arms, and legs. As the chilled water flows through the tubes, it absorbs the excess heat generated by the astronaut’s body and carries it away, helping to maintain a safe and comfortable body temperature.
In the microgravity environment of space, where there is no air to conduct heat away from the body, astronauts can quickly overheat or become too cold. The LCG helps regulate their body temperature and prevents overheating during physically demanding tasks, such as spacewalks or prolonged periods of physical activity.
