Transcription: In the vacuum of space, the lack of air pressure and oxygen along with fatal extremes of radiation and temperature make unprotected human life impossible. Space suits are designed to encase astronauts in a bit of the Earth's environment. The outer layer of the space suit is designed to stop micrometeoroids. These are tiny particles traveling at high speed in the vacuum of space which could injure the astronaut or by puncturing the suit cause fatal loss of air pressure. Insulation and cooling apparatus within the many layers of the spacesuit control the temperature. Other apparatuses supply oxy ...
