The famous 'spacesuit' is actually a 'super life jacket' for astronauts working in space. The space environment is extremely harsh—there is no air, and the temperatures are terrifying. Places touched by sunlight are as hot as an oven, while dark shadows are freezing cold like a giant freezer. The magical spacesuit not only fills with comfortable pressure and sweet oxygen, but it also acts like a smart air conditioner to regulate temperatures automatically, shielding astronauts from harmful cosmic rays. The gloves are designed to be super precise and flexible, making it easy for astronauts to tighten screws and hold tools in space. The helmet visor is coated with a shiny, special golden layer that works just like cool sunglasses to block blinding sunlight. Although a spacewalk suit is too heavy to wear on Earth, in the weightless environment of space, astronauts can wear it to work effortlessly for several hours!
