  1. Tools of an Astronomer After School Astronomy Clubs Dorian Janney

  2. How do we know what is out there in space? • We observe things in the night sky. • We wonder about the things we observe. • We design tools to use to learn about these things. • As our technology improves, our tools get better too!

  3. Ancient Astronomers • Observed and measured repeating patterns of Sun to create clocks and calendars • Used such tools as astrolabes to determine the positions of stars and planets in the night sky and to determine the latitude of ships at sea

  4. Telescopes

  5. Space-based Telescopes • Using space-based telescopes, we can see much further into space because we don’t have to look through the Earth’s atmosphere. • In 1990 the United States launched the first space telescope, called “The Hubble Space Telescope”

  6. Fly By Missions • These are missions that simply fly past an object, or maybe several objects in a long period of time. • Voyager 1 and 2, which were sent into space in 1977, sent us detailed images from the four gas giants- Jupiter, Saturn, Uranus, and Neptune.

  7. Orbiter Missions • These missions are sent in orbit around a planet, and allow us to learn about the planet as a whole. • They may stay in orbit for many years, and send us back so much information that we can create detailed maps of that planet’s surface.

  8. Lander Missions • A lander does just that- it actually lands on the planet. • What kinds of things might we be able to find out about a planet by landing on it? • Why can’t we send a lander mission to the Sun? • Why don’t we send people to other planets?

  9. Rover Missions • With Rover missions, we aren’t stuck in one spot on a planet or moon. • What do you think we might discover with a Rover mission that we couldn’t with another type of mission?

  10. Future Space Missions

  11. International Space Station • The International Space Station is the largest and most complex international scientific project in history. • Led by the United States, the ISS draws upon the scientific and technological resources of 16 nations: Canada, Japan, Russia, 11 nations of the European Space Agency and Brazil

  12. What would you design? • You will be our next generation of explorers! • Imagine you are designing a spacecraft- • What would you want to learn about? • What type of spacecraft might you design? • Where would you send your spacecraft?
