10 space exploration for us
- 1. Space Exploration for Us
- 2. Living in space is a very different experience from living on earth Space Exploration for Us Chris Hadfield - Wringing Out Water Chris Hadfield - Sleeping in Space
- 3. Daily tasks/routines cannot be performed the same way (as on Earth) due to zero gravity Space Exploration for Us Chris Hadfield - Brushing teeth in space Chris Hadfield - Preparing spinach
- 4. Astronauts prepare for the effects of zero gravity on earth via training... 1) Underwater: Water simulates the effects of zero gravity due to buoyancy acting against gravity Training under water: http://www.youtube.com/watch?v=GI6Z5LFEzCE Space Exploration for Us
- 5. Astronauts prepare for the effects of zero gravity on earth via training... 2) Airplane: When an airplane in the sky drops, passengers inside float up. Training in the air: http://www.youtube.com/watch?v=HQbAwE83phk Space Exploration for Us
- 6. Zero gravity means that astronauts will be spinning and rotating while floating, which may cause motion sickness. Astronauts train for this effect using a spinning chair. Spinning chair: http://www.youtube.com/watch?v=e-bHuEVO9Yw Space Exploration for Us
- 7. Space Exploration for Us High mineral density Low mineral density Zero gravity also means that there is less pressure/ stress on the bones, which causes them to lose their bone mineral density. This can lead to hip fractures later in life, especially for astronauts who spend months in space.
- 8. Space Exploration for Us To solve this problem, astronauts have to eat healthy and regularly exercise to keep their bones from losing calcium. Chris Hadfield on exercise: http://www.youtube.com/watch?v=Wam7poPzG1w

- 10. As well, free-fall (acceleration and gravity) produces G-forces (G = gravity) that can cause humans to feel discomfort and even black out. Astronauts (and pilots) train for these forces in a centrifuge. Centrifuge: http://www.youtube.com/watch?v=NWBMYV6S5gA Space Exploration for Us
- 11. There is also limited space inside a space shuttle, rocket, and/or space station, so astronauts may feel claustrophobic, especially since each journey takes a number of days. Space Exploration for Us
- 12. Astronauts must also have good team work and problem-solving skills. Many training programs require astronauts to solve various problems in a team with time limits. Space Exploration for Us
- 13. Interested in space travel? Space Exploration for Us You can travel as an astronaut/cosmonaut, or space tourist.

- 17. Space Exploration for Us You can also pay $20-35 million (US) to ride the Russian Soyuz rocket to the International Space Station (ISS) via the Space Adventures Company.

- 18. Space Exploration for Us Once on the ISS, you would be orbiting at a speed of 27 743.8 km/h, which means that it orbits around the earth once every 92 minutes 50 seconds.
