Spacewalks & EVAs are where human courage meets the raw reality of space. On Lyra Street, this category opens the hatch to one of the most breathtaking aspects of space exploration—when astronauts leave the safety of their spacecraft and step directly into the cosmos. Known as Extravehicular Activities, or EVAs, these missions are equal parts precision engineering, physical endurance, and awe-inspiring adventure. Here you’ll explore how spacewalks make modern exploration possible, from repairing satellites and assembling space stations to testing future technologies for the Moon and Mars. Discover the evolution of EVA suits, life-support systems, tools, and safety protocols that allow astronauts to survive and work in the vacuum of space. We dive into historic firsts, record-breaking missions, and the intense training required to prepare for weightless work hundreds of miles above Earth. Whether you’re fascinated by the science, the technology, or the human stories behind every tether and tool, Spacewalks & EVAs offers a front-row view of humanity literally reaching beyond its limits. This is where exploration becomes personal—and space feels closer than ever.
What Is a Spacewalk? How Astronauts Perform EVAs Explained
Step outside the spacecraft and into the impossible. This deep dive into spacewalks reveals how astronauts survive the vacuum, move in microgravity, and complete high-stakes missions in orbit. From cutting-edge suits to life-or-death precision, explore the science, skill, and bravery behind every EVA.
How Do Astronauts Breathe During a Spacewalk?
How do astronauts survive-and breathe-in the deadly vacuum of space? Step inside a spacesuit and explore the remarkable life-support systems that make every breath possible during a spacewalk. From oxygen supply to carbon dioxide removal, uncover the engineering marvels that keep astronauts alive beyond Earth.
