Mars is more like
Earth than any other planet
in the solar system.
It is named after the
Roman god of war
because of its red color. The first person to
observe Mars
with the use of a telescope was
Galileo Galilei.
He observed the Red Planet
in 1610.
In this video
we are going to learn about
the red planet Mars in depth.
Mars is the fourth planet
in orbit around the sun.
It's distance
from the Sun is
141.6
million miles
 
Scientists think there may
have been flowing rivers
on mars long ago.
It may be frozen
beneath the surface now.
Mars looks reddish because there is
a lot of iron in
the rocks of it's surface.
Iron is a metal
that rusts turning
red.
Several spaceships have traveled
to mars carrying equipment
to explore the planet.
Two rovers called Spirit
and Opportunity landed on
two sides of Mars
on January 2004.
The pictures
sent by these rovers were absolutely
stunning.
Here is a picture
of Victoria Crater taken by
the rover Spirit.
The tallest volcano
mountain in the solar system
is locate on Mars.
It is named Olympus Mons
and it seems to have a height of 21 km / 13 mi.
Which means
it is about two and a half times
of Mount Everest's
height above sea
level and little over
twice the height of
Mauna Kea, the volcano
in Hawaii, USA.
 
 
From the pictures
sent by those rovers we also get to know
that Mars has the biggest canyon
in the Solar System.
It is named Valles Marines.
It is ten times
larger and four times
deeper than Grand Canyon,
USA.
A rover called Curiosity
was launched from Earth in
2011 to land on Mars
in 2012.
One of it's jobs was
to pick up and look at the
rocks on Mars.
Do you know
one day on Mars is about
the same length of time
as one day on Earth?
Yup! You heard it right.
One day on Mars
is about 25 hours.
When one day on Earth
is 24 hours.
 
One Martian year
is 687
earth days.
Which means Mars
takes 687
days to orbit
the Sun once.
The average temperatures
on Mars is
-80 degrees Fahrenheit or
-60 degrees Celsius.
Another interesting fact
about Mars is
it has seasons just like Earth
but they last
longer. The longest season
on Mars is
spring, which lasts
for 194 days.
Autumn is the shortest one
which lasts for
only 142 days.
Mars
has two very small moons.
They are shaped like potato.
The moons are called Phobos
and Deimos.
Pretend you are
standing on Phobos.
When you look up Mars would cover
a huge part of
the sky. That's because
Mars is so close to
it's moon.
Mars has Attracted
researchers and scientists
for decades in search of
water and life.
And now new advanced
science and technology is
giving us hope
of first human
settlement on Mars in
near future.
Would you like settle on Mars
or you prefer to
be on earth? Do you
think human will pollute Mars
as much as they did
the Earth?
