Astronomy Tools and The Moon
UNIT 11STANDARDS: NCES 1.1.1, 1.1.2, 1.1.3, 1.1.4,
1.1.5, 2.1.1
LESSON 2
Lesson Objectives
In this lesson, you will learn about:– How light and telescopes are used to explore the
sky– Unmanned Space Missions– Man’s Quest for the Moon and Beyond– How to consider the formation of the moon
Astronomy
Astronomy studies the stars and planets. Since the stars and planets are far away, the
astronomer needs a tool to bring the image closer to study.
Remember telescopes also serve to warn us of meteors or asteroids that may pass close to Earth.
Telescopes
“Energy” Sources
Telescope Benefits
All objects in space emit energy.
Able to be modified to see different spectrum of energy.
Can record distant objects they view. Allow astronomers to use specialized
equipment to study the stars. Can make time exposures like a
camera. Generates a series of pictures to study the changes.
Reflecting and Refracting Telescopes
Reflecting Refracting Best places
Image focused by a mirror Image focused by a lens On mountains away from city lights
Satellites and Probes
Satellites
Probes
Devices placed into Earth’s low level orbit to study space.
Held in place by Earth’s gravity Used for weather, communications,
science Hubble Space Telescope is most famous
These are objects launched at other planets or bodies in space to send back data to Earth.

Section Review 11.2.1
Compare and contrast reflecting and refracting telescopes.
Why are satellites and probes important for space exploration?
Describe the development of unmanned space missions beyond the moon.
Describe the development of manned space exploration.
The Moon
The moon has always been the nearest space body to the Earth.
Man has always seen the moon and began to understand the phases of the moon.
1961 Russia launches Sputnik. The “Space Race’ was on.
President John Kennedy promised to put a man on the moon before the end of the decade.
July 20, 1969 Neil Armstrong becomes the first human to step onto the moon.
The Lunar Surface
Albedo
No atmosphere
Surface Impact Craters
Composition
The amount of light the moon’s surface reflects
With no atmosphere, the sun can heat the moon to 127oC or allow it to cool to –173oC.
There is no erosion on the moon. The moon is covered with impact
craters formed when meteors or asteroids hit the surface.
Composed of the same minerals on Earth
Formation Theories
The moon is not tectonically active.
Capture Theory. The moon was trapped by the Earth’s gravity and formed. NO same composition as the Earth
Simultaneous Theory. Formed at the same time as the Earth. No differences in iron.
Earth Spit.A large Mars size object impacted with the Earth (4.5 BYA).
The 2 objects merged. The moon was thrown
off or spit out of the Earth’s outer layers. The gases condensed to form the moon.
Earth Impact Theory
Section Review 11.2.2
Compare and contrast reflecting and refracting telescopes.
Why are satellites and probes important for space exploration?
Describe the development of unmanned space missions beyond the moon.
Describe the development of manned space exploration.
Discuss a possible theory for the formation of the moon.
