  1. Click once to begin. • All images from http://www.nasa.gov/ unless otherwise noted.

  2. What is the International Space Station? (ISS) • Science laboratory • Orbits the earth • 250 miles high • Astronauts take a shuttle to come and go from the earth.

  3. Who works on the ISS? • 16 countries have helped plan and construct the ISS, including: Russia Canada European Union Japan United States Brazil

  4. How big is the ISS? • Weight: 1 million pounds • Size: Almost as big as a football field

  5. How was the ISS built? • Astronauts and robots have put together the ISS piece by piece from 1998 until today.

  7. Can you see the ISS from Earth? http://www.astrophotographie.fr/ • Yes! This is a picture of the ISS passing in front of the moon.

  8. What do they do on the ISS? • Eat, sleep, play, and work! • Astronauts on the ISS do scientific research. • They answer questions such as the following…

  9. How long can people live in space? • Most astronauts stay on the ISS for 4-6 months. • Living in “zero gravity” weakens people’s muscles. • When astronauts come back to earth, they may be too weak to walk on their own.

  10. What do fire and water look like in “zero gravity”? • Fire doesn’t go up. • Water doesn’t go down. • Fire and water look like spheres in “zero gravity." • Flame on Earth Flame in “zero gravity” • http://www.me.berkeley.edu/cpl/research/fist/fist.html

  11. How can the ISS contribute to the good of humanity? • ISS astronauts study many things to help people, including: • Cures for disease (cancer) • How things grow in space (plants, animals, bacteria) • What the earth looks like during natural disasters • New types of materials and technology

  12. How can the ISS have enough energy to power itself? • Solar panels collect the sunlight. • The panels convert the sun’s energy into electricity.

  13. How do solar panels work? • Like plants collect the sun’s energy to grow, solar cells collect the sun’s energy to make electricity. • http://www.eoearth.org/article/Photosynthesis • http://www.energypoweralternatives.com/alternative-energy/do-solar-panels-work-when-its-cloudy/

  14. Use a solar cell. • Shine the flashlight on the solar cell to see what happens!
