Quick Summary
An extravehicular activity (EVA) backpack, also known as a life-support system, is a portable device that enables astronauts to survive and work in the harsh environment of outer space. These backpacks provide essential elements for physical well-being, including oxygen, temperature control, and waste disposal. They also contain cooling fluid, oxygen flow and recirculation equipment, a power source, and communication apparatus, ensuring astronaut safety and efficiency during spacewalks. The development of such systems traces back to the 19th century, with early efforts focusing on providing supplementary oxygen for high-altitude activities.12
