1.} how do they know there is water on the moon
They know there is frozen water, better known
as ice (liquid and gaseous water can't exist in
the low gravity and non-existent atmosphere of
the Moon), because of visual observations from
space but ice wasn't confirmed until the
Clementine Program which had a satellite orbit the
moon and take detailed pictures of it which
confirmed the presence of ice.
NASA was formed from several
divisions of the government in 1958, partly in
response to the development of the Soviet space
program. Late in 1957, the Soviets launched
Sputnik, the first human object to leave the
atmosphere of Earth. NASA wasn't invented by any
one person but was created to make a space program
that was competitive with the Soviets. Eisenhower
was president at this time and was actively
involved in seeing that the United States' space
and rocket programs were successful. Check out
the history section of the NASA website

3.} why do they call it the
I was unable to find any references to
check this but I think the word moon comes from
the Greek word for the moon which is Luna
(pronounced loona). Over the last 2,000 or 3,000
years, this word has changed with the development
of languages (in the 16th century in Britain, Moon
was spelled Moone) to the word Moon as we know it
today. Other related languages say it differently
(luna in spanish, lune in french, lua in
portuguese) but you can see how they are related
to the original Luna. I'm really not sure how the
"l" got changed to an "m" in english but I think
it has the same root.
4.} what year did the
Astronaute go to the moon and what are their
The first astronauts arrived on the moon
on July 16, 1969 on the Apollo 11 mission. The
first man to step on the moon was Neil Armstrong
who was with Edwin "Buzz" Aldrin in the lunar
lander. Also part of that mission was Michael
Collins who stayed in the command module that
orbited the moon.
Just recently, scientists have used radar to
detect water on the moon.The radar bounces off of
the moon, and it reflects differently when water
is present, so they were able to determine that
there actually is water on the moon. Actually the
moon is very cold, so the water is stored as ice.
NASA was founded on October 1, 1958.
NASA stands for the National Aeronautics and Space
Administration. This organization was created to
replace the National Advisory Committee on
Aeronautics. There were a lot of people involved
in creating NASA, so it is hard to single out a
single person, especially since it was an expanded
version of an existing organization. Here's a
question for you to research. What event led to
the creation of NASA? Hint: It happened on
October 4, 1957.
The word moon means "a
fairly large object orbiting around a planet."
Another word which means the same thing as "moon"
is "satellite." We use the word "moon" to describe
satellites of other planets. We say: Europa is
one of Jupiter's moons. Since Earth only has one
moon, I guess that people just started calling it
"the moon." Later, when people discovered moons
around other planets, they started calling them
moons" as well, and also gave them other
The first astronauts to walk on the
moon were Neil Armstrong and Edwin "Buzz" Aldrin
on July 20, 1969. There have been a number of
others to walk on the moon and you can find their
names and dates in an almanac or encyclopedia. For
