"The Genius Behind White & Orange Space Shuttle Suits"

Описание: "🚀 During NASA's Space Shuttle program (1981-2011), astronauts wore two distinctly colored suits—each with brilliant science behind it.
WHITE EMU SUITS (Extravehicular Mobility Units - Spacewalks):
✓ Reflect solar heat and sunlight (thermal control, not radiation protection)
✓ Multiple layers of specialized protective materials
✓ Outer thermal micrometeoroid garment uses ortho-fabric (Kevlar + Gore-Tex + Nomex)
✓ ~300 feet of water tubes in Liquid Cooling and Ventilation Garment (LCVG)
✓ Surface temperature protection: -250°F to +250°F
✓ Portable Life Support System (PLSS) backpack for vacuum operations
✓ High visibility against black space
ORANGE ACES SUITS (Advanced Crew Escape Suit - Launch/Landing 1994-2011):
✓ "International Orange" for maximum search-and-rescue visibility
✓ Designed for emergency survival during ascent/reentry
✓ Includes: parachute harness, flotation devices, radio, signaling equipment, emergency supplies
✓ Partial-pressure suit for intra-vehicular emergencies
✓ Lighter than EMU—no life support backpack
✓ Critical for cabin depressurization and water landing scenarios
Historical Context:
ACES suits retired when the Space Shuttle program ended in 2011. Modern missions (SpaceX Crew Dragon, Boeing Starliner) use different Intra-Vehicular Activity (IVA) suits, often in black and white designs.
