6.E.1 Understand the earth/moon/sun system, and the properties, structures and predictable motions of celestial bodies in the Universe.

3. Clarifying Objectives
6.E.1.3 Summarize space exploration and the understandings gained from them.

4. Essential Questions
What early theories & discoveries helped us gain knowledge about planets?
How do we use data gained by space exploration?
What instruments are used to collect data from space?
What discoveries made by space instruments help us better understand the universe?
What are the risks and benefits of the International Space Station?
How have the technologies developed in space enhanced our daily lives?

5. Early Space Theories (Ideas)
There were 3 early Astronomers that all had different ideas about the universe & the Earth
Ptolemy- thought that sun revolved around the earth (Geocentric)
Copernicus- discovered Earth Revolved around the sun (Heliocentric)
Galileo- supported Copernicus Heliocentric Theory

6. Essential Questions Get with a partner and answer the question…
What early theories & discoveries helped us gain knowledge about planets?

7. Space Data Instruments collect data about space
Our understanding of the Electromagnetic Spectrum allows us to make discoveries that we cannot see
The DATA we collect is SO IMPORTANT to understanding the Earth & the UNIVERSE that we live in

8. Essential Questions Get with a partner and answer the question…
How do we use data gained by space exploration?

9. NASA
NASA is a government organization in charge of Space Exploration in the United States
NASA stands for National Aeronautical Space Administration
NASA is the organization that makes most of the important space discoveries that we know of today

10. Space Instruments
Throughout history there have been many important discoveries about the universe we live in
They could not have been discovered without…
Hubble Telescope
Chandra X-Ray Observatory
Spitzer Telescope
Fermi-Gamma Telescope

11. Hubble Telescope
Hubble Telescope is the largest & most accurate telescope in Space
5 miles per second & takes pictures that are sent back to Earth

12. Chandra X-Ray Observatory
Chandra X-Ray Observatory is a place where astronomers can study X-Rays
It is an observatory that travels through space to detect X-Rays on the Electromagnetic Spectrum
These waves tell us that there is more in the universe than Optical (seeing) telescopes can see

13. Spitzer Telescope
Spitzer is an Infrared Telescope detecting Infrared Waves
It detects any material that is composed of Infrared Waves
Spitzer Telescope has provided much data that helps Astronomers understand more about the Earth & the Milky Way Galaxy

14. Fermi-Gamma Telescope
Fermi-Gamma Telescope detects Gamma Rays in Outer Space
It measures the Energy in the Gamma Rays
It also tells which direction the Gamma Rays are going

15. Essential Questions Get with a partner and answer the question…
What instruments are used to collect data from space?

16. Many Objects Discovered
Instruments have discovered many things in Space that are not planets
These include…
Comets
Asteroids
Stars
Vacuums
Black holes
Moons
Other Universes

17. Essential Questions Get with a partner and answer the question…
What discoveries made by space instruments help us better understand the universe?

18. International Space Stations Good or Bad??
Disadvantages (BAD)
Very Expensive
Space Station Needs REPAIR
Astronauts are risking their LIVES all the time
Advantages (Good)
Gateway to the Universe
Improves International Relations
Research & Discovery Capabilities
Better than anything we can do from Earth

19. Essential Questions Get with a partner and answer the question…
What are the risks and benefits of the International Space Station?

20. Space Impacts our Life
We use many things in our daily lives that without space discoveries we would not have…
Microwaves
Calculators
Fire Retardant Clothing
Bar Coding

21. Essential Questions Get with a partner and answer the question…
How have the technologies developed in space enhanced our daily lives?

22. Understandings from Space Exploration
We have learned so much from Space Exploration
The most important thing to keep in mind is discoveries in space has helped us learn more about the Earth & Universe we live in

23. EOG Questions
Which represents information that is gained as a result of space exploration?
A) weather and climate patterns that occur on Earth
B) existence of the sun and the moon in the solar system
C) how to use coal and natural gas as energy resources
D) location of plates found upon Earth’s surface

24. Important Points
Space Exploration began thousands of years ago with Ptolemy, Galileo, & Copernicus
Space Exploration has provided us with useful DATA
We have used the data in how we build, inventions we have made
We have many different INSTRUMENTS we use to make Space Discoveries
We use space discoveries in our daily lives everyday
Microwaves
Calculators
Fire Retardant
Bar Codes
Space Exploration helps us understand Earth & the Universe where we live
