Microgravity

• Explaining the effects on the human body

Microgravity

• The condition of microgravity comes about
  whenever an object is in free fall.
• That is, it falls faster and faster, accelerating
  with exactly the acceleration due to gravity
  (1g). As soon as you drop something it is in a
  state of free fall.

Creating Microgravity Conditions

• NASA uses a variety of facilities to create
  microgravity conditions. The most famous way is
  by aircraft flying in parabolic arcs to create
  microgravity for tests and simulations that last
  20-25 seconds. NASA's Johnson Space Center, for
  example, operates a C-9 Low-G Flight Research
  aircraft also known as the "Vomit Comet."

How does space travel effect the human body?

• Fluid congestion causes head congestion and puffy

How does space travel effect the human body?

• Fluid redistribution shrinks legs
• Astronauts must exercise several hours each day
  to counteract this effect.
