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 {{radiation astronomy resources}} template, you should have adequate background to get 100 %.

Suggestion: Have the lecture available in a separate window.

Enjoy learning by doing!

Hypotheses

Main resource: 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.
