Space Exploration Tools Notes Exam Questions with
100% Correct Answers
Optical and radio telescopes, space probes spectroscopes, and artificial satellites
The tools for space exploration
Collect observations and data about objects in the Solar System and beyond
What tools for space exploration are designed to do
Optical telescopes
Collect visible light and use convex lenses or mirrors to collect and focus the light
Produce bigger, brighter images of distant objects in space
Optical telescopes
Refracting telescopes
Use two convex lenses to focus light. Limited in size because of the weight of the lenses
Reflecting telescopes
Use two mirrors to focus light
Radio telescopes
Receive or collect radio waves emitted from objects in space. Waves are collected in a huge dish.
Three football fields
The diameter of the largest radio telescope dish
Receives more light than those on Earth's surface
One reason why optical telescopes in orbit around earth are better than telescopes on earth
Light entering Earth's atmosphere is scattered, weakening amount of light reaching Earth's surface
One reason why optical telescopes in orbit around earth are better than telescopes on earth
Viewing stars and planets during the day are hampered by daylight and clouds
One reason why optical telescopes in orbit around earth are better than telescopes on earth
Brightness of lights from man-made surface features blocks the light from planets and stars
One reason why optical telescopes in orbit around earth are better than telescopes on earth
Hubble telescope
Orbited Earth since 1990 providing some of best images of objects in space
Advantages of radio telescopes
