Comprehensive Artificial Gravity Directory: A-Z Guide
This image of the International Space Station, captured by Expedition 56 crew members from a Soyuz spacecraft after undocking, highlights the absence of artificial gravity in today's space stations. NASA astronauts Andrew Feustel, Ricky Arnold, and Roscosmos cosmonaut Oleg Artemyev completed a fly-around of the station before returning to Earth after 197 days in microgravity. As the space station celebrated the 20th anniversary of its first module, Zarya, in November 2018, the exploration of artificial gravity continues to be a key challenge for future long-term space missions.

Introduction to Artificial Gravity: The Key to Long-Term Space Exploration
Artificial gravity is one of the most intriguing and critical concepts in the pursuit of long-term space exploration. As humans venture deeper into space, overcoming the challenges of microgravity becomes essential for the health and well-being of astronauts on extended missions. Artificial gravity seeks to recreate the gravitational forces experienced on Earth within spacecraft, space stations, and even future colonies on the Moon and Mars. By mimicking Earth’s gravity, it can prevent the adverse physiological effects of prolonged weightlessness, such as muscle atrophy and bone loss, while also providing a sense of normalcy in space. This Artificial Gravity Directory serves as a comprehensive resource, exploring a wide range of topics related to artificial gravity—its scientific principles, technological innovations, and its vital role in the future of human spaceflight—from A to Z. Whether you're a space enthusiast, researcher, or engineer, this guide offers everything you need to understand and explore the potential of artificial gravity.
