  1. The Moon Race

  2. Summary • Start of Race • Causes • Different Approaches • United States Strategy • Mercury / Gemini / Apollo • How to get there. • Soviet Union Strategy • L3 Plan • How to get there. • Strategy Comparison • Achievements and Disappointments

  3. Start of Race • United States is considered second to the USSR for space-flight capabilities. • USSR first for: satellite, man, woman, spacewalk… • President Kennedy’s challenge: "...I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important in the long-range exploration of space; and none will be so difficult or expensive to accomplish..." • Single goal for US: put Man on Moon.

  4. Start of Race • USSR not accepting immediate challenge: • Khrushchev wants new and exciting space events. • Does not want to ally with the United States for a Moon quest – fear of revealing secret technologies. • Focuses on permanent human presence which leads to Salyut missions; Cold War purpose as well.

  5. United States Strategy

  6. United States Strategy • Apollo program initially supposed to be Earth orbital flights; after Kennedy’s speech, new plans laid out. • Mercury: • Study human space-flight capabilities. • Gemini: • Study long term space-flight effects. • Development of space navigation – dockings, meetings, two-manned crafts. • Apollo: • Moon Lander and orbiter tests. • Tri-manned crafts.

  7. United States Strategy Mercury Gemini Apollo

  8. United States Strategy • Before man, robots. • Pioneer: film the Moon surface while orbiting. All 3 fail, fourth becomes a solar satellite instead. • Rangers: • Goal is to land. Fourth probe lands 1962, three years after the Soviets. • New goal: to crash land and “snap before death.”

  9. United States Strategy • Surveyor: • Goal to soft land and determine land composition • Lunar Orbiter Project – Map out Moon using pictures and mapping 99% of Moon. • Conclusion: Astronauts can walk on the Moon.

  10. United States Strategy • Mercury • Sub-orbital and orbital flights to test human capabilities to work in space. • First two flights sub-orbital, last four orbital, lasting longer periods (from 3 orbits to 22 ½ orbits.) • Single manned spacecrafts. • Tested two different rocket types, • Tested heat-shield technologies. • Only six men launched into space.

  11. United States Strategy • Gemini • Only two days and six hours of manned spaceflight recorded for the United States after Mercury Project, although Kennedy already declared the race to the Moon: need a step in between to learn more and prepare. • Primary purpose to demonstrate space rendezvous and docking techniques. • Two manned spacecrafts. • 16 Astronauts.

  12. United States Strategy • Apollo • To collect Moon samples. • Place scientific experiments on surface of another celestial body. • Test whether or not humans can work on other world. • 12 astronauts leave foot prints. • Program that introduced first loss of US lives for space – Apollo 1.

  13. United States Strategy • Build the Saturn V rocket, largest launch vehicle to ever leave Earth’s atmosphere, 1968. • Lunar Module (LEM / LM) first flight in Jan 1968. • Command Module built in 1966 – Apollo 1 fire in 1967 causes redesign. • Both spacecraft link and form an internal tunnel inside the spacecraft for astronauts to move about the cabin.

  15. United States Strategy

  16. United States Strategy

  17. United States Strategy • Plan agreed upon is known as the Lunar Orbit Rendezvous: • Launch from Cape Canaveral, FL (Kennedy today.) • In Earth orbit, dock two spacecrafts. • Three to four day trip to Moon. • Burn phase where spacecraft enters Moon gravity field. • Separation of spacecrafts.

  18. United States Strategy • LEM descent to Moon. • CM Orbits Moon. • LEM Ascension back to dock with CM. • Jettison of LEM in lunar orbit. • CM return to Earth and lands in Ocean.

  19. United States Strategy

  20. United States Strategy • Lunar orbit procedure: • Two of the three astronauts travel down the tunnel into the Lunar Module. • Both ships separate, LEM starts descent. • CM pilot orbits Moon while other teammates walk on Moon. • LEM launches from Moon surface and docks with CM. • Both tunnel hatches re-opened, crew travels back to CM. • Exit of Moon orbit, back for Earth.

  21. United States Strategy

  22. United States Strategy

  23. United States Strategy • To expand exploration radius on Moon, NASA developed Moon Rover:

  24. United States Strategy • Apollo 7: CM test flight around Earth. • Apollo 8: First human orbit around Moon. • Apollo 9: LEM test flight around Earth. • Apollo 10: LEM test flight around Moon. • Apollo 11: First human footprint on Moon. • Apollo 12: Moon landing. • Apollo 13: Explosion inside Service Module – Mission Cancelled. • Apollo 14: Moon Landing. • Apollo 15, 16, 17: Moon landing and Rover.

  25. Soviet Union Strategy

  26. Soviet Union Strategy • Soviets aim for the Moon soon after Sputnik success, 1959. • Soviets begin designing their rocket, the N1, before Kennedy’s challenge. • Military wants ICBMs instead • Korolev, Chief Designer, convinces Khrushchev to fund Moon program in 1964. • Lunar Project called L3 Project: land cosmonauts on Moon.

  27. Soviet Union Strategy • Project LK-1to send cosmonauts around Moon. • Tight infighting within the space program. • Different booster quarrels brings delays and gambles. • Kuznetsov, booster builder, does not test first stages of rocket. • Khrushchev gone in 1964: LK-1 cancelled.

  28. Soviet Union Strategy • Before man, robots. • Luna Program: 1959 to 1976 • Luna 2: 1st Moon impact • Luna 3: Flyby, first far-side view. • Luna 7, 8: Impact • Luna 9: Moon landing, Feb 1966 • Luna 10, 11, 12, 14: Lunar orbiter • Luna 16: Sample return to Earth, Sept 1970 • Luna 17: Moon rover, Nov 1970

  29. Soviet Union Strategy • N-1 is launch vehicle. • LOK = Command Module. • LK = Lunar Module. • LOK is a slightly modified Soyuz spacecraft, still in use today by Russia.

  30. Soviet Union Strategy • Soviet Plan to Reach Moon: • The N1 rocket delivers the spacecraft system into the low-Earth orbit. • Both spaceships connect. • 3 to 4 -day flight between the Earth and the Moon. • One cosmonaut transfers from the LOK spacecraft to the LK lander, during an EVA. • LK spacecraft separates from the LOK spacecraft and heads for Moon. • Engine firings onboard the LK lander provides for a soft-landing on the Moon surface.

  31. Soviet Union Strategy • Engine firing provides for the liftoff of the LK ascent stage from the lunar surface and reaching lunar orbit. • The spacecrafts dock. • The cosmonaut transfers from the LK lander to the LOK spacecraft during a spacewalk. • LOK capsule separates from living module, reenters Earth atmosphere and lands somewhere in Soviet Union.

  39. Achievements

  40. AchievementsUnited States Neil Armstrong - Buzz Aldrin Michael Collins Apollo 11 July 20, 1969

  41. AchievementsUnited States

  42. AchievementsUnited States • First manned orbit of the Moon, Apollo 8. • First landing on the Moon and man on Moon, Apollo 11. • First vehicle with wheels on Moon, and first vehicle to be driven by man on Moon. • Achieved within time limit imposed by Kennedy, even after his assassination.

  43. AchievementsSoviet Union • First to: • Flyby the Moon. • Impact on the Moon. • Snap pictures of the far side of the Moon. • Land on the Moon. • Land automatic Rover. Robotic Probes

  44. Drawbacks

  45. DrawbacksUnited States • Apollo 1 astronauts Gus Grissom, Roger Chaffee and Ed White die during test. • Apollo 13: “Successful failure.” • $136 billion for Apollo project.

  46. DrawbacksSoviet Union • Robotic determination not present for manned spaceflights. • Kuznetsov does not test first stages of N-1 rocket – results in all three tests to fail. • Rockets explode on launch pad or while in the air. • It takes time to convince the Soviet government to fund Moon project, loosing precious time in the race.

  47. DrawbacksSoviet Union • Soviet government changes in 1964, and Moon race, behind Americans, looks less and less promising. • Military still not interested in Moon – they’re happy about Salyut. • First Soyuz fails: capsule to bring Soviets to the Moon does not work, more delays.

  48. DrawbacksSoviet Union • Failure of all N-1 launches. • Lack of support from government. • Soyuz spacecraft inability to function. • Americans already on the Moon. • No purpose for military • All of these lead to cancellation of project.

  49. DrawbacksSoviet Union • Cancellation of project meant they would have to accept failure. Did the Soviets want that? • No : they destroy remaining N-1 spare parts, launch pads and lock up designs to go for the Moon into classified folders, some of which still haven’t re-emerged.
