NASA leverages Extended Reality (XR)—including Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR)—to train astronauts for missions more efficiently, safely, and realistically than traditional methods. From spacewalk simulations to Mars rover operations, XR is a critical tool in preparing for the challenges of space exploration.
Key Applications of XR in Astronaut Training
**1. *Spacewalk (EVA) Training in VR*
- Neutral Buoyancy Lab (NBL) + VR Integration
- Astronauts train underwater in NASA’s giant pool (simulating microgravity) while wearing VR headsets to overlay virtual spacecraft (e.g., ISS modules).
- Haptic gloves simulate resistance when handling tools in a spacesuit.
- Dynamic Emergency Scenarios
- VR simulates ammonia leaks, solar radiation spikes, or tether failures during EVAs.
**2. *ISS & Lunar Gateway Operations (AR/MR)*
- Procedural Training with AR Overlays
- Microsoft HoloLens 2 guides astronauts through equipment repairs with step-by-step holographic instructions.
- Used in NASA’s Sidekick and T2 Augmented Reality projects.
- Remote Expert Assistance
- Ground control can annotate real-time AR instructions for complex tasks.
**3. *Mars & Lunar Surface Simulations (VR/MR)*
- Mars Rover Operations
- Astronauts train in VR Martian landscapes to practice driving rovers (e.g., Perseverance Rover simulations).
- Lunar Habitat Construction (Artemis Program)
- MR helps visualize habitat assembly in 1/6th gravity conditions.
**4. *Medical & Emergency Response Training*
- Zero-G Medical Procedures in VR
- Simulates surgical interventions, CPR, and trauma care in microgravity.
- Fire & Depressurization Drills
- VR replicates smoke-filled modules for emergency response training.
**5. *Psychological & Team Preparedness*
- Isolation Stress Testing
- VR simulates long-duration missions (e.g., Mars transit) to study crew behavior.
- Team Coordination in VR
- Astronauts practice collaborative repairs in shared virtual environments.
