1 National Aeronautics and Space Administration EXPLORATION NASA Johnson Space Center Houston: We Are Go For Exploration!

2 National Aeronautics and Space Administration EXPLORATION Why do we need a space suit? Temperature extremes Oxygen Pressure micrometeoroid and orbital debris protection protection from dust and rocks

3 National Aeronautics and Space Administration EXPLORATION Scientific Method THINK!! Try Again!

4 National Aeronautics and Space Administration EXPLORATION Past Space Suits Mercury ProgramApollo Program Gemini Program

5 National Aeronautics and Space Administration EXPLORATION Mercury Space Suits Purpose: Protect astronaut from space vacuum Derived from Navy Mark- IV high altitude aircraft pressure suit Designed for unpressurized comfort Vehicle provided life support via umbilical Operating Pressure: 3.7 psi (25.5 kPa) Mercury Crew Capsule

6 National Aeronautics and Space Administration EXPLORATION Gemini Space Suit Purpose: First US space suit used both inside and outside the vehicle Derived from USAF AP/22 high altitude aircraft pressure suit Designed for unpressurized comfort Incorporated cooling system Vehicle provided life support via umbilical Operating Pressure: 3.7 psia (25.5 kPa) Gemini Crew Capsule

7 National Aeronautics and Space Administration EXPLORATION Apollo Space Suits Purpose: Keep astronaut alive during Earth and lunar launch/re-entry, microgravity EVA, and lunar EVA Improved mobility features at shoulder, waist, knees, lower arms, and wrists First space suit with a portable life support system (PLSS) Operating Pressure: 3.7 psia (25.5 kPa) Apollo Command Module with Lunar Lander

8 National Aeronautics and Space Administration EXPLORATION Present Space Suits Advanced Crew Escape Suit (ACES) Extravehicular Mobility Unit (EMU)

9 National Aeronautics and Space Administration EXPLORATION Advanced Crew Escape Suit Purpose: Keep astronaut alive in event of an emergency during launch and re-entry Derived from USAF pressure suits Protects from loss of cabin pressure Integrated life preserver and raft, parachute and harness, emergency oxygen, and survival gear Operating Pressure: 3.46 psi (23.9 kPa) Space Shuttle

10 National Aeronautics and Space Administration EXPLORATION Extravehicular Mobility Unit (EMU) Purpose: Low Earth Orbit spacewalks Designed for movement in microgravity Modular design to fit various sizes of astronauts Protects from micrometeoroids Portable life support system Operating Pressure: 4.3 psi (29.6 kPa) International Space Station

11 National Aeronautics and Space Administration EXPLORATION Communications Carrier Assembly (CCA) Independent microphones and earphones Internal Components of the EMU Suit Engineer (2006) Its like your air conditioner, but uses water instead! Liquid Cooling and Ventilation Garment (LCVG) Neil Armstrong (1969)

12 National Aeronautics and Space Administration EXPLORATION Modular Components of the EMU Helmet and Extravehicular Visor Assembly (EVVA) Hard Upper Torso (HUT) and Arm Assembly Lower Torso Assembly (LTA)GlovesBoot and Foot Restraint

13 National Aeronautics and Space Administration EXPLORATION EMU Controls and Life Support Display and Controls Module: temperature, pressure, ventilation and communication controls Portable Life Support System

14 National Aeronautics and Space Administration EXPLORATION Apollo 16: Charles Moss Duke, Jr. (Duke)

15 National Aeronautics and Space Administration EXPLORATION What about a suit for future exploration? What about a suit for future exploration?

16 National Aeronautics and Space Administration EXPLORATION Mark III Suit

17 National Aeronautics and Space Administration EXPLORATION Rear Entry I-Suit (REI-Suit)

18 National Aeronautics and Space Administration EXPLORATION Suit Development Using the Scientific Method System Testing Component Testing Concept Development Cool POGO Movie Develop innovative concepts to meet challenging requirements Develop innovative concepts to meet challenging requirements Test parts and refine designs per test results Test system and refine per test results Integrated Testing Integrate hardware to test how it works together
