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)
