  1. Space Travel and Its Effects on Humans

  2. Leaving Earth • http://spaceplace.nasa.gov/how-orbits-work/en/ • http://galileoandeinstein.physics.virginia.edu/more_stuff/flashlets/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

  3. 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.

  4. 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

  5. Space Food • EFFECTS: Foods will float away-crumbs are a problem Foods will spoil (no fridge) • ACCOMMODATIONS: Special packages to prevent it from flying away Prepared and stored properly to avoid spoilage

  6. Waste Management • EFFECTS: Without gravity, waste doesn’t 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

  7. 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

  8. 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 (reducing waste and recycling) Acclimating yourself with work and surroundings Disinfecting supplies
