MECH 372 / ENGR 372
Space Systems Design and Engineering II
 
Assignment #1 - Introduction to Space Systems
 
NOTE - IF YOU COMPLETED THIS ASSIGNMENT WHILE TAKING MECH 371, YOU DO NOT NEED TO COMPLETE THIS ASSIGNMENT AGAIN.
 
Objective: The objective of this assignment is to demonstrate an understanding of the basic motivations, structure, characteristics, and issues relating to space missions. 
1. Text Problem 1.1-1

2. Text Problem 1.1-2

3. Text Problem 1.2-3

4. Text Problem 1.2-4

5. Text Problem 1.2-5

6. Text Problem 1.2-11.  Do parts (a) and (b), but note that defining the "mission" means that you should describe all of the topics as specified in Problem 1.2-3.

7. Text Problem 2.1-2.  Forgive me, but this is such a great question given SCU's Jesuit heritage.  Challenge - I would be very interested if any of you would like to do a little bit of research into the Jesuit reaction to Copernicus's work. If done well, I would give you 3-5 min in class to present your findings.

8. Text Problem 16.1-1.  Comment on each

9. Text Problem 16.2-6.

10. Text Problem 16.3-9

11.  Benchmark the IKONOS, GPS, SpaceWay-1, and GeneSat-1 missions by filling in the following table (you should be able to fill out the vast majority of this table).  Additional references in addition to the textbook include the links below - and in some cases you may need to do additional research.  Note that full credit is given for having ~80% of each column generally correct, so if you can't find every last detail, that's OK.  The point is to find this info so that you can see the similarities and differences across satellites used for very different purposes.
