  • 10 space exploration for us

    1. 1. Space Exploration for Us
    2. 2. Living in space is a very different experiencefrom living on earthSpace Exploration for UsChris Hadfield - Wringing Out WaterChris Hadfield - Sleeping in Space
    3. 3. Daily tasks/routines cannot be performed thesame way (as on Earth) due to zero gravitySpace Exploration for UsChris Hadfield - Brushing teeth in spaceChris Hadfield - Preparing spinach
    4. 4. Astronauts prepare for the effects of zero gravityon earth via training...1) Underwater: Water simulates the effects ofzero gravity due to buoyancy acting againstgravityTraining under water: http://www.youtube.com/watch?v=GI6Z5LFEzCESpace Exploration for Us
    5. 5. Astronauts prepare for the effects of zero gravityon earth via training...2) Airplane: When an airplane in the skydrops, passengers inside float up.Training in the air: http://www.youtube.com/watch?v=HQbAwE83phkSpace Exploration for Us
    6. 6. Zero gravity means that astronauts will be spinningand rotating while floating, which may cause motionsickness.Astronauts train for this effect using a spinning chair.Spinning chair: http://www.youtube.com/watch?v=e-bHuEVO9YwSpace Exploration for Us
    7. 7. Space Exploration for UsHigh mineral density Low mineral densityZero gravity also means that there is less pressure/stress on the bones, which causes them to lose theirbone mineral density. This can lead to hip fractureslater in life, especially for astronauts who spendmonths in space.
    8. 8. Space Exploration for UsTo solve this problem, astronauts have to eathealthy and regularly exercise to keep their bonesfrom losing calcium.Chris Hadfield on exercise: http://www.youtube.com/watch?v=Wam7poPzG1w
    9. 9. Space Exploration for Us
    10. 10. As well, free-fall (acceleration and gravity)produces G-forces (G = gravity) that can causehumans to feel discomfort and even black out.Astronauts (and pilots) train for these forces in acentrifuge.Centrifuge: http://www.youtube.com/watch?v=NWBMYV6S5gASpace Exploration for Us
    11. 11. There is also limited space inside a spaceshuttle, rocket, and/or space station, soastronauts may feel claustrophobic, especiallysince each journey takes a number of days.Space Exploration for Us
    12. 12. Astronauts must also have good team work andproblem-solving skills. Many training programsrequire astronauts to solve various problems in ateam with time limits.Space Exploration for Us
    13. 13. Interested in space travel?Space Exploration for UsYou can travel as anastronaut/cosmonaut, or space tourist.

    15. 15. Space Exploration for UsVirgin Galactic has already started takingreservations in 2005. Here are the packages:You can book online today @ http://www.virgingalactic.com/booking/
    16. 16. Space Exploration for UsTo prepare for your journey…
    17. 17. Space Exploration for UsYou can also pay $20-35 million (US) to ride theRussian Soyuz rocket to the International SpaceStation (ISS) via the Space Adventures Company.Flight experience: http://www.youtube.com/watch?v=V8I7xJ0MBpgTour of the ISS: http://www.youtube.com/watch?v=aFlqAeUMM6U
    18. 18. Space Exploration for UsOnce on the ISS, you would be orbiting at a speed of27 743.8 km/h, which means that it orbits around theearth once every 92 minutes 50 seconds.Feeling speed on ISS: http://www.youtube.com/watch?v=v8SV9Rz_958Chris Hadfield: http://www.youtube.com/watch?v=5LrDpfdrJkA
