EVA (Extravehicular Activity) practice

EVA, or Extravehicular Activity, refers to any work astronauts do outside their spacecraft in space. It typically involves astronauts donning specially designed space suits that provide life support, protection from radiation, and mobility. Practice sessions, often called "spacewalk training," take place in large pools filled with water to simulate the weightlessness and environment of space. This training helps astronauts learn how to move, handle tools, and perform repairs safely outside their vehicle. Effective EVA practice ensures astronauts are prepared for real missions, maintaining safety and mission success in the challenging conditions of space.
