What are conditions like in space?

• Space is a vacuuma place with almost no matter.
• Temperatures in space are extremely hot or
  extremely cold.
• Objects and people in space experience a feeling
  of weightlessness, or microgravity. Without the
  force of gravity to work against, astronauts in
  space must find ways to exercise to slow the loss
  of bone and muscle.

1. Identify Identify three conditions of space
that are different from conditions on Earth.

Effects Space has on Humans

• Ions in space cause radiation that can cause
  cancer
• Earth has 1G force space has varying G Forces
  which causes muscle loss , heart rhythm
  dysfunction, heart and vision impairment, balance
  problems
• Bone loss at a rate of 1 to 1.5 a month.

What are space shuttles?

• A space shuttle is a reusable spacecraft. A
  space shuttle can carry a crew and equipment into
  space, return to Earth, and then be reused for
  the same purpose. Most shuttle missions last an
  average of nine days.

What are space stations?

• A space station allows long-term observations
  and experiments to be carried out in space. Space
  shuttles are used to take people and supplies
  from Earth to the space station. Most astronauts
  stay on the space station for four to six months.
