hlets/slingshot6.swf EFFECT: The Space Shuttle has to fight the
effects of gravity pulling and has to have enough power to get into
orbit without going too far out in space ACCOMODATIONS: The rockets
give the space shuttle the right amount of boost. The speed will
put the space craft in orbit
Slide 4
Effects of Microgravity on the Body EFFECT: Blood & fluid
building up in parts of the body. Muscles & bones weaken due to
underuse. Spine lengthens- leads to back pain. ACCOMODATIONS:
Taking medications and exercising as often as possible. Most of the
effects reverse themselves upon returning to Earth.

Pressure, Temperature, & Atmosphere Changes EFFECTS: No
atmospheric pressure (lungs explode, body fluids boil), no oxygen,
and extreme temperatures ACCOMODATIONS: Spacesuits are pressurized
to keep body fluids liquid, contain tanks of oxygen for breathing,
shield the astronaut from extreme temperatures, and shield them
from flying debris

Space Food EFFECTS: Foods will float away-crumbs are a problem
Foods will spoil (no fridge) ACCOMMODATIONS: Special packages to

Waste Management EFFECTS: Without gravity, waste doesnt fall
from the body Build-up of wastes, wastes floating away Shower?
ACCOMMODATIONS: Toilets that flush with air, not water, to pull
waste away Recycle waste water, seal solid wastes in bags Sponge
bath or enclosed shower with a vacuum
Slide 8
Living & Working in Space EFFECTS: Motion sickness, stuffy
head, claustrophobia, illness How do you sleep in a bed?
ACCOMMODATIONS: Taking medications to treat symptoms in some cases
Sleep in sleeping bags strapped to wall, ear plugs and sleep
masks
Slide 9
Spacecraft EFFECTS: Having enough supplies (food, water, etc)
Being able to live and work in small space Keeping supplies clean
(germs) ACCOMMODATIONS: Bringing food, water, & extra supplies
