Spacewalk: A History of Extravehicular Activities
Spacewalks, officially known as extravehicular activities (EVAs), represent humanity's audacious ambition to explore the cosmos beyond the confines of spacecraft. The first spacewalk was a momentous event. On March 18, 1965, Soviet cosmonaut Alexei Leonov emerged from the Voskhod 2 spacecraft, marking the beginning of human endeavors beyond the confines of spacecraft. These early spacewalks were primarily focused on testing equipment, performing maintenance tasks, and conducting scientific observations.
Key Aspects of Spacewalks:
- Preparation: Rigorous training and meticulous planning are crucial for ensuring the safety of astronauts during spacewalks.
- Suit Design: Advanced spacesuits provide astronauts with vital life support systems, protection from the harsh environment of space, and mobility for performing tasks.
- Tethers and Safety: Safeguarding astronauts during spacewalks is paramount, achieved through tethers, safety lines, and protocols for emergency procedures.
- Technology: Spacewalks rely on sophisticated technology, such as maneuvering units, tools for repairs, and communication systems to maintain contact with the spacecraft.
