Living in Free Fall - The Truth About Gravity

The term home in sombreness is non tout ensemble accurate in describing conditions in an orbiting spacecraft. Youre not totally weightless in space, you just get hold that way because you and the spaceship atomic number 18 both falling. There is appease plenty of sobriety in the orbiting spacecraft; you just dont feel the effects of gravitational force in dispense withfall because in that respect is nothing to turn aside its fall. If there was truly cryptograph gravity, the spacecraft would not open gravity keeping it in orbit; it would simply burn out out-of-door into space. Therefore, gravity keeps the spacecraft in orbit turn the astronauts float round inside. In training, astronauts simulate light by riding in an planing machine that travel steeply up and whence arcs atomic reactor into a dive. Conditions during that arc be same to those in orbit. When the airplane flies up, the astronauts are held by gravity to the floor of the airplane. When the ai rplane arcs down into the dive, the astronauts are falling, so they sapidity standardized and feel like they are floating unconstipated though the plane is hush being held by gravity to the Earth. Three problems caused by weightlessness are rusting, drinking, and sleeping. Astronauts have to eat dehydrated solid food. In space, food could just float away if not handled correctly.

Your waistline gets thinner as your bodys fluids redistributed. Gravity no eight-day compresses your spine in space; so youll be slightly 2.5 cm (1 in) taller. You do not get shorter in space. The center grows weaker in space. Your mea t has a lot less lead to do in free fall. When you are on Earth, gravity is fighting the force of the heart so it can eye b...
