About This Chapter
Space Science Technology - Chapter Summary
Let us help you increase your understanding of the technology scientists use to observe and learn about space. Our instructors discuss several types of telescopes and how they are used. You'll also examine the history of space travel, and look at the benefits and drawbacks of manned space missions. After watching all these lessons, you should be prepared to:
- Give facts about reflecting and refracting telescopes
- Describe the types of reflecting telescopes
- Look at interferometry and radio telescopes
- Explain the pros and cons of various types of space missions
- Report on the history of space travel
- Analyze the dangers and benefits of space travel
While these lessons may go over material you studied in high school and college, they'll probably provide some new facts as well. You can watch the videos as your schedule allows, on a computer or mobile device. The quizzes that follow each lesson let you check your mastery of the subject and show you where you need additional study.
1. Types of Telescopes: Radio, Reflecting & Refracting Telescopes
Learn about the different types of telescopes that astronomers use: X-ray, radio, gamma ray, reflecting and refracting. Learn what the differences are between them and what different things they show us about the universe.
2. Refracting & Reflecting Telescopes: Key Concepts
This lesson will discuss some key terms and concepts relating to the refracting and reflecting telescope: primary mirror/lens, eyepiece, focal length, focal point, chromatic aberration, and achromatic lens.
3. Different Kinds of Traditional Reflecting Telescopes
This lesson will discuss three major kinds of traditional reflecting telescopes and their major differences. These include the Newtonian, Cassegrain, and Schmidt-Cassegrain telescopes.
4. Radio Telescopes & Interferometry
This lesson will go over some key concepts related to radio astronomy. We'll cover what radio telescopes are, the basics of how they function, and what their disadvantages are compared to optical telescopes and how this is resolved.
5. Space Mission Types: Advantages & Disadvantages
This lesson will go over four different types of space missions scientists have conducted, including flyby, orbiter, rover, and human space explorations.
6. Space Travel: History, Dangers & Benefits
Space is fascinating. Humans have been sending objects into space for decades, trying to learn about Earth and what's beyond. But while space travel can be beneficial, there are also risks that come along with exploring the rest of the universe.
