#### Transcript of Moon

Moon By: Natasha Bohl Introduction
We have accomplished so many things on the moon. We have walked on the moon, we landed a lunar module, we put a satellite orbiting the moon, we even put an american flag on the moon. We learned a lot from the moon. People even use to think that the moon was made of cheese-_-! Measurements
The moon is 150 million kilometers away from the Sun. Measurements
The moon is approximately 405,000 kilometers away from the Earth. Measurements The circumference of the moon is 6,784 miles (10,917 km) The diameter of the moon is 3,476 km. Measurements The moon orbits Earth at a speed of 2,288 miles per hour (3,683 kilometers per hour). Measurements When sunlight hits the moon's surface, the temperature can reach 253 degrees F (123 C). The "dark side of the moon" can have temperatures dipping to minus 243 F (minus 153 C). Measurements It takes 27.3 days to make one revolution Measurements It takes 27.3 days to make one rotation. Measurements The moon has an angle of approximately 0.54° Composition The Moon is made from many of the same things that we find here on Earth. Scientists studied about 800 pounds of moon rocks brought back by the Apollo astronauts. Their tests showed that the rocks from the Moon are similar to three kinds of igneous rocks that are found here on Earth: basalt, anorthosites, and breccias. Composition The moon has an atmosphere just it not a very big one. One source for the atmosphere is outgassing, from radioactive decay processes deep inside the crust and mantle of the Moon. Another comes from debris kicked up by micrometeorite impacts on the surface of the moon. Composition The moon has no moon. Geology There are many theories to of how our moon was formed but the Giant Impact theory (hypothesis) is that the Mars-sized body collided with Earth, throwing vaporized chunks of the planet's crust into space. Gravity pulled the blasted particles together, creating a moon. Space Exploration Geology
Greek Moon Smybol Brief history of human exploration of the moon: In 1959 Luna 2 became the first spacecraft to land on the moon's surface. A third Luna mission captured the first, blurry, images of the far side of the moon. On July 20, 1969, Neil Armstrong and Edwin "Buzz" Aldrin became the first people to reach the moon when their Apollo 11 lunar lander touched down. Space Exploration History/ Discovery: We don't exactly know who discovered the moon. There could have been people before that we didn't even know of. In 1959, the first successful mission to the moon was documented. Russian astronauts landed an unmanned shuttle, which brought back hundreds of pounds of rocks to study. It is impossible to say when or how the moon was discovered. Interesting Facts a.)When Alan Shepard was on the moon, he hit a golf ball and drove it 2,400 feet, nearly one half a mile.
b.)In a survey 13 percent of the people thought the moon was made of cheese
c.)The multilayer space suits worn by the astronauts to the moon weighed 180 pounds on earth, but thirty pounds on the moon due to the lower gravity.
d.) The Apollo missions brought back 2196 rock samples weighing 382 kg in total.
e.)The moon is not a planet, but a satellite of the Earth.
f.)The surface area of the moon is 14,658,000 square miles or 9.4 billion acres.
g.)Only 59% of the moon's surface is visible from earth.
h.)The dark spots we see on the moon that create the image of the man in the moon are actually craters filled with basalt, which is a very dense material.
