What is the purpose of the layers in a space suit?

The layers in a space suit serve multiple critical purposes, including thermal insulation, pressure regulation, and protection from micrometeoroids and radiation. The outer layer is designed to shield against harsh environmental conditions, while inner layers provide life support by maintaining temperature and supplying oxygen. Additionally, the suit's design allows for mobility and flexibility, enabling astronauts to perform tasks in space. Together, these layers ensure the astronaut's safety and functionality during missions beyond Earth's atmosphere.
