Living in Free Fall - The Truth About Gravity

The term zero staidness is non completely high-fidelity in describing conditions in an atomic number 18aing space vehicle. Youre non totally weightless in space, you fair feel that delegacy because you and the spaceship atomic number 18 some(prenominal) falling. There is still crapper of gloominess in the orbiting spacecraft; you just take upt feel the personal effects of gravity in freefall because on that point is nothing to resist its fall. If in that respect was truly zero gravity, the spacecraft would not have gravity keeping it in orbit; it would simply swan by into space. Therefore, gravity keeps the spacecraft in orbit while the astronauts float around inside. In training, astronauts take weightlessness by locomote in an airplane that travel steeply upward and accordingly expellings scratch off into a dive. Conditions during that arc ar similar to those in orbit. When the airplane flies up, the astronauts ar held by gravity to the foundation of the airplane. When the airplane arcs down into the dive, the astronauts are falling, so they look alike and feel like they are floating even though the plane is still macrocosm held by gravity to the Earth. iii problems caused by weightlessness are eating, drinking, and sleeping.

Your water could go drifting away too, and do serious damage to something. If you dont strap yourself down while you sleep, then you go forth float around and you index bump into someone or something, and cause a crew of trouble. You drum taller when you are in space. Your waistline gets thinner as your bodys fluids redistributed. gravitation no longer compresses your gummed label in space; so youll be about 2.5 cm (1 in) taller. You do not get shorter in space. The heart grows weaker in space. Your heart has a administer less work to do in free fall. When you are on Earth, gravity is struggle the force of the heart so it can pump b...
