REVIEW EXAM II
(Part 2)
This exam is primarily about the Apollo Program, which was a step by step process to get
to the moon.
Know about The Fire: who died in it? What was learned? What Apollo mission was this
named? How might it have save the crew of Apollo 13?
Know how many Apollo missions that were flown: what was one or more main objective
of each mission? How many went out to the moon? How many involved a landing on
the moon? How many men walked on the moon? What were some of the obstacles that
were overcome on some of these missions? What was Apollo-Soyuz and which Mercury
astronaut flew on it?
Apollo 8 went to the moon: it was a controversial decision, which did not fit in with the
original plans. What are at least two reasons that this new mission for Apollo 8 was
undertaken? Apollo 11 was the first landing: What are some of the difficulties did
Armstrong and Aldrin experienced during powered descent? Know the story of Apollo
13 (what happened to their space craft? How did they survive?). Which Apollo missions
were cancelled? Why? (this is in the book).
There are several milestones in an Apollo mission. I outline them below. Be prepared to
describe any one of them and know the order in which they take place (given below)
1. launch
2. earth parking orbit (EPO)
3. trans lunar injection burn (TLI)
4. docking with and extraction of the LEM
5. passive thermal control (PTC)
6. lunar orbit insertion (LOI)
7. lunar parking orbit burn (LPO)
8. LEM inspection/separation
9. LEM landing orbit burn
10. LEM powered descent (on first orbit if all systems GO)
11. lunar stay/EVA
12. lunar liftoff (ascent stage of LEM)
13. rendezvous and docking of CM and LEM
14. cast off LEM
15. trans earth injection burn (TEI)
16. passive thermal control (PTC)
17. cast off CSM
18. reentry
19. recoverey
