What is the major advantage of space-based telescopes (such as the Hubble Space Telescope) over Earth-based telescopes?

• They are millions of miles closer to the subject.

• They are less expensive to build and maintain.

• They are above the Earth’s atmosphere which can cause distortions.

• They are affected less by the gravity of the Earth and the Moon.

A space mission to Mars detected the presence of argon in its atmosphere. Which type of instrument was in the space mission to Mars that helped detect the presence of argon?

• radio telescope

• reflector telescope

• satellite

• spectroscope

How does the presence of such powerful telescopes help scientists?

• The telescopes collect detailed images of the behavior of phenomena on distant objects.

• The telescopes deflect harmful cosmic rays in space.

• The telescopes are used as global positioning systems.

• The telescopes collect detailed weather data.

How do the two telescopes compare?

• The refracting telescope uses lenses to focus light, while the reflecting telescope uses mirrors.

• The refracting telescope uses incoming radio waves to focus light, while the reflecting telescope uses mirrors.

• The refracting telescope uses lenses to focus light, while the reflecting telescope uses radio waves.

• The refracting telescope uses mirrors to focus light, while the reflecting telescope uses lenses.

What is the advantage of placing instruments in high orbits?

• The instruments are located in an environment with less gravity.

• Researchers are able to conduct repairs and modifications to the instruments better.

• The instruments can be larger in size and mass to carry more detection equipment.

• Gases in Earth’s atmosphere do not interfere with the instruments gathering data.

An astronomer wants to gather information on the gravitational field of a planet in the solar system. Which technology would the astronomer send to the planet to get the required data?
