15 Points Per Correct Answer - No time limit  

1. NASA calls the Hubble Space Telescope an "orbiting observatory". What is the main advantage that an orbiting, or space-bound telescope, has over an earth-bound telescope? It is less expensive to build It does not need a power supply It does not require a focusing system It is not affected by earth's atmosphere or weather

2. One of the original goals of the Hubble Space Telescope was to find an accurate value for the Hubble Constant. What is the Hubble Constant? the intensity of light emitted from a star the speed that a galaxy moves away from us (on earth) is proportional to its distance from us the rotational speed of a galaxy is related to it diameter the relative age of the universe compared to the Milky Way galaxy

3. The Hubble Space Telescope has sent back amazing images of nebulae, including the Horsehead Nebula and the Ring Nebula. What is a nebula? the material around a dying star a distant galaxy a meteor shower an ice field around outer planets

4. What instrument on the Hubble Space Telescope allows scientists to get the most information on the chemical composition of celestial bodies? the Space Telescope Imaging Spectrograph the Fine Guidance Sensors the Wide Field and Planetary Camera the Faint Object Camera

5. The Wide Field Camera 3 is due to be installed in the Hubble Space Telescope in 2008. What light spectrum does this instrument use? the ultraviolet spectrum the visable light spectrum the infrared spectrum all of these

6. To test the instruments on the Hubble Space Telescope, NASA technicians wear "bunny suits", which are protective suits that cover their heads, torso, legs and feet. The main reason they wear these suits is: To keep a neutral electical charge on the technicians To protect against scratching the instruments To protect the instruments from lint and other contaminents To protect against personal injury from the instruments

7. How are major repairs or upgrades to the Hubble Space Telescope made? Repairs or upgrades are made by robots The repairs or upgrades are made by on-board computers Astronauts perform the repairs or upgrades Repairs or upgrades are not made- the instruments have a limited life

8. The Wide Field Camera aboard the Hubble Space Telescope does not have real lenses. True False

9. Like land-based telescopes, the Hubble Space Telescope has a primary mirror. What is special about this mirror? It has a honeycomb shape to save weight It has a magnesium fluoride overcoat It can withstand changes in temperatures All of these

10. The NASA facility most involved in the mission of the Hubble Space Telescope is: Marshall Space Flight Center Kennedy Space Center Jet Propulsion Laboratory Goddard Space Flight Center
