Earth orbits/Astronomy/Quiz

Earth-orbit astronomy is a lecture of radiation astronomy courses project that may be included in courses like principles of radiation astronomy.

You are free to take this quiz at any time.

Once you’ve read and studied the lecture itself, the links contained within the article/lecture, listed under See also, External links, and in the template, you should have adequate background to get 100 %.

Suggestion: Have the lecture available in a separate window.

Enjoy learning by doing!

{Yes or No, A Low Earth Orbit (LEO) is 6,530 to 8,370 km distant from the center of the Earth. + Yes - No
 * type=""}

Hypotheses

 * 1) Earth-orbit astronomy from sufficient altitude should be able to almost replace sounding rockets.
 * 2) The much lower cost of balloons or sounding rockets keeps them as a value.
