MARS!
The Red Planet
By Lindsey Provencher and Haley
Rainier! 
Main Differences between
Mars and Earth!
• Mar’s solar day is 39 minutes and 35.244
seconds longer than Earth’s day!
• One earth year is 365 days and one mars
year is 687 days!
Mars’ Atmosphere!
• Made up mostly of Carbon dioxide (95%)
• Nitrogen 3% argon 1.6%
• Liquid water can’t exist because the
Atmosphere is too thin.
• Only a little bit of water can exist on the
thin clouds, but there is signs of ancient
floods
Materials Mars is made of!
• Outer surface-basalt that was brought to
the surface by ancient volcanoes
• The volcanoes put iron oxide dust with a
fine powder consistency on the surface
• That dust gives the planet its red color
• The core is mostly iron and 17% sulfur
• The core is surrounded by the mantle
which is made of silicates
Mars compared to the Earth and
Sun!
• Mars is 230 million km from the sun
• Mars is 35 million miles from the Earth
• Mars and Earth are both terrestrial
planets, which means they have the same
makeup (core, mantle, crust)
Mars’ color!
• Red
• The iron oxide on the surface makes it red
• The iron oxide creates a very powdery red
dust
Name of Mars!
• Mars is also known as the red planet
• Mars, the name came from the Roman’s
god of war.
• The blood-like color is related to the
Roman’s god of war
• The Egyptians named mars “ Her Desher”
meaning the “red one”
Mars’ moons!
•
•
•
•
•
•
•
Two moons- Phobos and Deimos
Deimos is the smaller moon ( 15x12x11) km
Orbits around Mars every 30 hours
Small, lumpy, and heavily cratered
Phobos is the larger moon (27x22x18) km
Orbits around mars 3 times a day
Phobos is on a collision course with mars
Travel time: Earth to Mars!
• Approximately 214 Earth days or a little
over 7 months
• It would take less time if we had
technology to carry enough fuel to travel
directly to Mars
• You would have to slow down once you
take off, so you could enter Martian orbit
• You could get to Mars faster with a
nuclear-powered rocket
Mars’ Surface!
• Mars’ surface is similar to Earth’s moon
• Has a reddish color which comes from the
iron oxide in the soil
• The surface also holds Magnesium,
Chloride, Potassium, and Sodium
• The soil could grow organisms such as
asparagus
Mars’ Geographic features!
• Mars has Olympus Mon- highest mountain
in the solar system
• Mars has Valles Marineris- the largest
canyon
• Mars has polar ice caps
• Mars has canyons and volcanoes
Exploration of Mars!
• 1964 to 1970, Mariner was sent, it was the
first successful space craft
• We have sent space crafts to reach Mars
and explore it
• Sent exploration rovers- Mars Rover in
2003
Discovery of Mars!
• There is not a known person who discovered
Mars
• Astronomers such as Aristotle saw Mars and
classified it as a star
• The Astronomers could see Mars because it
is so bright
• 1659- Christian Huygens discovered features
of Mars
• He thought there was life on Mars, but it was
actually water canals.
Temperature on Mars!
• Extremely cold temperature
• Average surface temperature is -63
degrees Celsius can fall as low as 140
degrees Celsius and as high as 20
degrees Celsius
• The temperature on Mars is colder than
Earth temperature, because Mars is
farther from the sun and Mars has a
thinner atmosphere so it can’t hold heat
Mars time!
• A Mars day is only 39 minutes and 35
seconds longer than Earth’s day
• One Earth year = 365 Earth days
• One Mars year = 687 Earth days
Mars’ Seasons!
• Mars’ seasons are very similar to Earth’s
• Mars’ seasons are twice as long because
Mars has significantly longer years
• Seasons are similar because Mars has an
axial tilt of 25.19 degrees which is close to
Earth’s tilt
Rotation!
• It takes Mars 687 Earth days to rotate
around the sun.
• It takes Mars 669 Martian days to rotate
around the sun.
• Martian days are also called Sols
The Fun facts of Mars!! ;D
• Mars’ mass is 6.42x10 to the 23rd power
kilograms
• Mars’ volume is 163,115,609,799 cubic
kilometers
• Mars is 230,000,000 kilometers from the
sun
• Mars’ diameter is 6787 kilometers
• Mars has no rings
Human life on Mars!
• Mars does not support human life, but it
may have billions of years ago
• Evidence of human life has been found
• Evidence included: traces of water, and
the proper setting for life
• The only living things that could possibly
survive on Mars now are micro-organisms
in the soil and dust
Interesting Facts!
• A day in Mars is equal to 24.6 Earth hours
• If you weigh 100 lbs. on Earth, your weight
on Mars would be 38 lbs. (multiply your
actual weight by 0.38)
• The orbital speed of Mars is 24.2
Kilometers per second
• Mars is the God of War in Roman
mythology (Ares)
