MARS!The Red Planet
By Lindsey Provencher and Haley Rainier!
Main Differences betweenMars 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)
