If you are interested in learning more information about the space suits NASA astronauts use and some of the tools they carry when making repairs and building work during space walks, you might be interested in this video created by the Tested team when Norman Chan and Will Smith from Tested visited NASA to learn how astronauts dress.
The Tested team explains: “We’ve all seen NASA’s white space suit that astronauts have been wearing since the Apollo missions. But what does an astronaut wear underneath that iconic suit’s shell? We visit NASA to learn about all the essentials of extravehicular space wear, all the way down to the emergency diapers.”
The Evolution of Space Suits
Space suits have come a long way since the early days of space exploration. The suits used during the Apollo missions were designed to protect astronauts from the harsh environment of space, including extreme temperatures, micrometeoroids, and the vacuum of space. These early suits were bulky and cumbersome, but they were essential for the safety of the astronauts.
Modern space suits, such as the Extravehicular Mobility Unit (EMU) used by NASA today, are much more advanced. They are designed to provide greater mobility and comfort while still offering the necessary protection. The EMU consists of several layers, each serving a specific purpose. The innermost layer is a liquid cooling and ventilation garment, which helps regulate the astronaut’s body temperature. The outer layers provide protection from micrometeoroids and radiation.
Tools and Equipment for Space Walks
In addition to their space suits, astronauts carry a variety of tools and equipment when performing space walks. These tools are specially designed to be used in the microgravity environment of space. For example, astronauts use a tool called a pistol grip tool, which is similar to a cordless drill but is designed to work in space. This tool is used for tasks such as tightening bolts and screws.
Astronauts also carry a tool called a tether, which is used to secure them to the spacecraft while they are working outside. This is important because, in the microgravity environment of space, even a small push can send an astronaut drifting away from the spacecraft. The tether ensures that they remain safely attached.
Another important piece of equipment is the Simplified Aid for EVA Rescue (SAFER), which is a small, backpack-like device that astronauts wear during space walks. SAFER is equipped with small thrusters that allow the astronaut to maneuver in space if they become untethered from the spacecraft.
