Balloons for astronomy is a lecture about the lofting technology of balloons to place astronomical detectors above nearly all of the Earth's atmosphere. It is part of an effort to describe lofting technologies in astronomy.

You are free to take this quiz based on balloons for astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{repellor vehicle}} template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz

[edit | edit source]

  

1 Yes or No, Balloons provide a long-duration platform to study any atmosphere, the universe, the Sun, and the near-Earth and space environment above as much as 99.7 % of the Earth's atmosphere.

No
Yes

2 Which of the following is associated with balloon astronomy?

a long-duration platform
ULDB project
the Moon
a low-cost, quick-response method
lighter-than-air gas
launched where the scientist needs to conduct the experiment

3 Yes or No, The various background effects OSO 1 encountered prompted the flight of similar detectors on a balloon to determine the cosmic-ray effects in the materials surrounding the detectors?

No
Yes

4 Which of the following is not a balloon astronomy experiment?

HEFT
HIREGS
CSBF
MAXIS
BLAST
