Space Exploration: Is it worth the cost?

Introduction to the Essay:

How many of the planets in our solar system have been photographed up close or visited by space probes from Earth? ALL OF THEM!  :)  What have we learned about them that couldn't be learned with Earth-based observations?  Surface features, existence of minor moons, existence of rings, properties such as magnetic fields, composition of rocks, and so on. Have any of the moons or planets in the solar system been explored by astronauts?  YES! Our own moon!  :)



Assignment:

So, my question to you is:  What value is there in exploring space?  If there is value in exploring space, is there any real value in sending people to explore space or just nonliving beings like robots or space probes?

Please read pages 92 and 93 in your Astronomy Textbook (Science Explorer).  Then, you will write an essay about your opinion based on facts and your own knowledge you gained from the unit.  Be sure that you provide your opinion about where you stand on the issue.

The main question is:  How much is space exploration really worth to human society? Does it outweigh the costs? What are the benefits and what are our limitations?

Questions to be answered in paragraph form:

1.  In your own words, discuss the various costs and benefits of space exploration.

2.  Make suggestions for three different approaches to space exploration:  sending humans to the moon or another planet, doing only Earth-based research, and one other opinion/suggestion for possible space exploration.

3.  What are the benefits and drawbacks of each of these approaches.

4.  Imagine that you are a member of Congress (government), who has to vote on a new budget (money to be spent).  There is a fixed amount of money to spend, so you have to decide which needs to your country is the most important.  Discuss the top five to ten priority areas (such as medical research, health, transportation systems, roadways, education, science studies, etc...).  Give back-up or your reasonings for your decision. Which would get the most funding (money)?  Where do you think space exploration should be in your prioritized list?

Concluding thoughts...
