Their spacesuits supply them with oxygen, keep their bodies at controlled temperatures, remove moisture from the air around them, and monitor their blood pressure and heart rhythm. When Neil Armstrong went on the Apollo 11 mission that sealed his place in history as the first man to land on the moon, his suit was specially designed to provide a life-sustaining environment during periods of extra vehicular activity or unpressurized spacecraft operation. The custom-fitted spacesuit permitted maximum mobility and was designed to be worn with relative comfort for up to 115 hours outside the spacecraft or for 14 days in an unpressurized mode. Astronauts must put an enormous amount of trust in their spacesuits. One said it was eerie to realize that while outside the space capsule, there was just one-quarter of an inch between him and eternity.
Man is different from every other creature in regard to clothing.
All of the other creatures in God s kingdom were born with their clothes on, so to speak. The covering they need grows from the inside out, and some animals even shed their old clothes periodically and develop new ones. Man is the only creature whose clothes must come from the outside. The Bible tells us that artificial clothing was first introduced after Adam and Eve ate the forbidden fruit in the Garden of Eden. The Hebrew word for aprons is the equivalent of belts.
