Meet Astro
Greetings boys and girls! My name is Astro the
Astronaut. I have known Mr. Valle since he first
began exploring the moon when he was in 3rd
grade. Now, he asked if I would meet you!
3
Meet Astro
Of course, I said yes. My favorite thing to do
in this whole universe is to teach people about
my favorite place. Can you guess what my
favorite place is?

Meet Astro
If you guessed the moon, youre right! The moon
is much more than a mysterious ball in space. In
fact, we know a lot about the moon. Why dont
you tell me what you would like to know first.

Earths satellite
The moon is Earths nearest neighbor. Dont let
that fact fool you though. It is still pretty
far away. If you were driving in a car going 55
mph, it would take you 6 months to get there!
7
Earths satellite
In addition to being a neighbor, the moon is
Earths satellite. A satellite is an object that
revolves (moves around) a planet. The moon
continuously circles around the Earth.
8
Earths satellite
The moon circles around the Earth because of a
force called gravity. Gravity is the force of
attraction between two objects of mass. Earth
has a lot of mass. The moon has mass too.
9
Earths satellite
The Earth is much bigger (has more mass) than the
moon. In fact, if Earth was hollow, over 50
moons could fit inside it. Since Earth is
bigger, it pulls the moon around it.
10
Earths satellite
If the moon was bigger than Earth, then Earth
would orbit around the moon. This, of course,
is not the case.
11
Earths satellite
Remember, the bigger the object, the more it
pulls. I know this can be tough stuff. If
this seems a bit confusing, make sure to ask
questions in class.

Moon features
First, let me explain that the moon is NOT made
of cheese. Ive been to the moon many times. It
looks like a grey dusty desert. It also has many
interesting features.
15
Moon features
The moon has many large dark spots. These spots
are actually very smooth areas that have been
filled with hardened lava.
16
Moon features
Each of these lave-filled areas is called a
mare. The plural form of mare is maria.
17
Moon features
There are also thousands of big dents in the
moon. These were caused from huge chunks of rock
that crashed into the moon with great force.
18
Moon features
We call these dents in the moon craters. Craters
can be as small as 3 centimeters or as big as 150
miles!
19
Moon features
In addition to maria and craters, the moon has
rays. Rays are light colored streaks going out
from craters.
20
Moon features
When craters were formed from crashing rocks,
splashes of matter poured out. These created the
rays.
21
Moon features
Someday, you might visit the moon and see all
this for yourself! For now, keep on learning!

Moon phases
Im certain youve noticed that the moon doesnt
always look the same from Earth. Some people
think the moon changes shape. This is not true.

24
Moon phases
In fact, the moon remains the same shape at all
times. What changes is the placement of the moon
in relation to Earth and the sun.
25
Moon phases
Every month, the moon goes through a series of
phases. These phases repeat themselves over and
over throughout the year..
26
Moon phases
The following slides will explain why the moon
seems to change shape in each of its different
stages.
27
Moon phases

• One half of the moon is always lit.
• The lit half is the one that faces the sun.

28
Phase 1 new moon

• We start with a new moon. This is when the moon
  is between Earth and the sun.

29
Phase 1 new moon

• When there is a new moon, the sun lights up the
  side that faces away from Earth.

30
Phase 1 new moon

• Since the lit part of the moon faces away from
  Earth, we do not see a moon at night.

31
Phase 2 First quarter

• As we approach a first quarter moon, we see more
  and more of the moons lit half.

32
Phase 2 First quarter

• Eventually, we see half of the moon in the sky.
  At this point, we have reached phase 2.

33
Phase 3 Full Moon

• Eventually, the moon lines up so that Earth sits
  exactly in the middle of it and the sun.

34
Phase 3 Full Moon

• In this phase, we see the entire part of the lit
  moon. This is a full moon.

35
Phase 4 last quarter

• After a full moon, we gradually see less and less
  of the moon again.

36
Phase 4 last quarter

• When the moon looks like it is half a circle
  again, it is the last quarter phase.

37
AROUND AND AROUND

• After a full moon, we gradually see less and less
  of the moon again.

38
AROUND AND AROUND

• Soon it will be between the sun and Earth again.
  We are back to the new moon phase.

Moon exploration
People have been studying the moon and space for
ages. The fancy name we have for the study of
objects in space is astronomy.
41
Moon exploration
A man by the name of Galileo began modern
astronomy when he invented the first telescope.
This was nearly 500 years ago.
42
Moon exploration
Another way we explore space is by using
satellites. These satellites gather important
information from space and send it back to Earth.

43
Moon exploration
Sputnik is the name of the first satellite ever
sent into space. This was done by the Soviet
Union in 1957.
44
Moon exploration
Recently, we have also been studying space by
actually going there! This is known as space
travel.
45
Moon exploration
In 1961, Alan Shepard become the first American
to enter space. Since then, America has been
part of many special space missions.
46
Moon exploration
One very special space travel program was called
the Apollo Project. Its purpose was to land
people on the moon. The goal of this project was
accomplished in 1969.
47
Moon exploration
In 1969, Apollo 11 brought the first astronauts
(space explorers) to the moon. The first two
people to set foot on the moon were Neil
Armstrong and Edwin Aldrin.
48
Moon exploration
Nobody has set foot on the moon since 1972. We
still spend a lot of time studying it, however.
In fact there are plans to someday return to the
moon and place a telescope there.
49
Moon exploration
Maybe someday you will become the next person to
walk on the moon! Explore and discover! Thats
my motto.
