Humans evolved to perfectly suit the conditions on Earth. To venture out of the atmosphere, we need to artificially create these conditions. With durable and reliable materials and the most up-to-date technology and engineering, spacesuits surround the body with a bubble of air at the same pressure as that felt on our planet. Oxygen is stored and pumped to the head for breathing in environments that an exposed body would suffocate in.
The person recognised for inventing the concept of the spacesuit is Spanish scientist Emilio Herrera, who dreamed of reaching the stratosphere, though his missions were in the form of a hot-air balloon ride into a less hostile environment than today’s space missions, Herrera created a
