Space and Space Exploration

1. Space and Space Exploration

2. Speed of Light speed light travels through space (300,000 km per sec)

3. Radiation energy that is transmitted from one place to another by electromagnetic waves (light from a star)

4. Electromagnetic radiation radio waves and visible light from the sun

5. Electromagnetic spectrum arrangement of electromagnetic waves according to their wavelengths; Includes radio waves, microwaves, infrared radiation, visible light (rainbow of colors), ultra violet radiation, X rays, and gamma rays

6. The electromagnetic spectrum

7. Visible light shows visible light wavelengths

8. Telescope used to view distant objects

9. Optical Telescope uses light to produce magnified images of objects

10. Types of Optical Telescopes refracting telescope – optical telescope that uses a double convex lens to bend light and form an image at the focal point reflecting telescope – optical telescope that uses a concave mirror to focus light and form an image at the focal point

11. Observatory building that houses an optical telescope; often has a dome-shaped roof that can be opened for viewing (Brazos Bend State Park)

12. Radio Telescope Collects and records radiowaves traveling through space; can be used day or night under most weather conditions

13. Rocket A special motor that can work in space and burns liquid and/or solid fuel.

14. Space Shuttle reusable spacecraft that can carry cargo, astronauts, and satellites to and from space

15. Spacesuit Provides a safe and protected environment for the astronaut

16. Satellite Any natural (moons) or artificial object that revolves around another object.

17. Space Probe Instrument that travels far into the solar system, gathers data, and sends them back to Earth.

18. Orbit A curved path followed by a satellite as it revolves around an object.

19. Hubble Space Telescope • Launched in 1990 by the space shuttle Discovery • Has been repaired by 3 missions (’93, ’97, ’99) • Shows clear images of space because it is outside of the Earth’s atmosphere

20. First Missions to Space Sputnik –Soviet capsule that was the first to put a human being in space (1961) Project Mercury – First step in U.S. space program to reach the moon, it orbited a piloted spacecraft around Earth and brought it back safely

21. Project Gemini – Second stage in the U.S. space program to reach the moon, in which and astronaut team connected with another spacecraft in orbit Project Apollo – Final stage in the U.S. space program to reach the moon, in which Neil Armstrong was the first human to step on the moon’s surface (July 21, 1969)

22. Neil Armstrong’s Famous Words……… “That’s one small step for man, one giant leap for mankind.”

23. International Space Station Large facility with living quarters, work and exercise areas, and equipment and support systems for humans to live and work in space and conduct research not possible on Earth. Permanent laboratory designed for long-term research projects

24. REVOLUTION The movement of one object around another. Earth takes 365 days (1 year) to revolve around the sun.

25. Comet A large body of frozen ice, dust, and rockthat orbits the sun

26. Impact Crater from a meteorite hitting the Earth Meteorite Any space fragment that survives its plunge through the atmosphere and lands on Earth’s surface.

27. Solar System System of planets and numerous other objects that orbit the Sun, all held in place the Sun’s gravity.

28. Rotation • The spinning of Earth on its axis • Causes day and night • Earth rotates every 24 hours.

29. Meteoroid small chunk of rock and metal in space

30. Asteroid large chunk of rock and metal found in space

31. Meteor a meteoroid that completely burns up as it passes through the Earth’s atmosphere
