1. Chapter 11: Section 3 Exploring Earth’s Moon

2. The First First Spacecraft: Luna (Russian) First to take pictures 1959 When was Sputnik Launched?

3. Ranger Missions Plagued by technical failures Ranger 7 (1964) sends back detailed images Total of 9 spacecrafts

4. Surveyor First soft landing- Surveyor 1 (1966) Paved the way for the Apollo program First pictures from the surface

5. Clementine First U.S. lunar mission in more than two decades. First spacecraft to photograph the Moon's south polar region. Found evidence suggesting that ice exists in a permanently shadowed crater at the lunar south pole.

6. BW: Section 3 Questions 1.True or False: Only one side of the Moon receives sunlight. The other side will always be in darkness hence the dark-side of the Moon. (1pt) 2.What was the first American probe to send back images from the Moon? (1pt) 3.What was the name of the first spacecraft to make a soft landing on the Moon? (1pt) 4.What Apollo mission was the first to land on the Moon? (1pt) 5.Is there water on the Moon? Explain (2pts)

7. Clementine Mapping the Moon’s Surface Crust facing Earth is Thinner. Possible Reason? Earth’s Gravity

8. Impact Basins Depression Left behind Why would you expect to find ice in them at the poles? –Sunlight will not hit the bottom of the crater.

9. Lunar Prospector Orbited Moon from pole to pole Data showed a small iron core Supports Impact Theory of origin –Material blasted from Earth’s crust and mantle

10. Icy Poles Water ice is present at both poles Estimated that the Moon has 3 billion metric tons of water ice
