Preparing for extravehicular activity
Spacewalks, or EVAs, require extensive, specialized training to master bulky spacesuit systems, complex procedures, and fine motor tasks in a hazardous environment. Training builds muscle memory, situational awareness, and team coordination.
Typical EVA training elements:
- Neutral buoyancy training in large pools to replicate weightless movement and tool handling.
- Virtual reality and mockups for procedure rehearsal and spatial orientation.
- Hands-on practice with suit hardware, tethers, and tools.
- Contingency training for suit malfunctions and emergency protocols.
Team and mission integration
- Crews rehearse full mission timelines, choreographing movements with ground support.
- Physical conditioning emphasizes stamina and strength for working in pressurized suits.
- Communication drills refine coordination between spacewalkers and internal crewmembers.
This layered training regimen prepares astronauts to safely execute assembly, maintenance, and scientific tasks during spacewalks.
