Spacesuits are like special superhero costumes for astronauts! 🦸♂️ They keep them safe in space where there's no air to breathe and it's very cold or hot.
Here's what they do:
The suit is like a bubble around the astronaut with a helmet so they can see where they're going!
Spacesuits are amazing mini-spaceships that astronauts wear! 🚀 They solve all the problems of being in space:
| Problem in Space | How Spacesuit Helps |
|---|---|
| No air to breathe | Has oxygen tanks & removes CO2 |
| Extreme temperatures | Multiple insulation layers |
| Radiation | Special protective materials |
| Micrometeoroids | Strong outer layer |
The suit has over 14 layers of material and weighs about 280 pounds on Earth (but feels weightless in space)!
Modern spacesuits are technological marvels with these key systems:
Provides oxygen (0.3-0.7 psi), removes CO2, and regulates humidity. The Primary Life Support System (PLSS) is like a wearable spaceship with 8 hours of supplies.
Uses Liquid Cooling and Ventilation Garment (LCVG) with 300 feet of tubing circulating water. Outer layers have aluminized Mylar for insulation.
Outer layer is Ortho-Fabric - a blend of Kevlar, Nomex, and Gore-Tex that can withstand impacts at 17,500 mph!
Joints use convoluted bearings and constant volume joints to allow movement while maintaining pressure. Gloves have silicone fingertips for touchscreen use.
