Mars: The Red Planet
Mars: The Red PlanetBy Sarah Wolbach
What does Mars mean?Roman god of warRed color is associated with bloodObserved by Ancient Romans
Discovery of MarsFirst observed by Egyptians 1570 B.C.Galileo Galilei was the first to view Mars through a telescope 1610 A.D.
Distances Fourth planet from the sun227,940,000 km away Distance from the Earth:Varies because of their orbitsAvg. 225 million km
Planet MeasurementsMass 6.42 x 1023 kmVolume 1.63 x 1011 kmGravity 3.71 m/s2Density 3.93 g/cm3Mars would sink in water because it is more dense than water.
Orbit and Rotation687 Earth days to orbit the sun24 hours and 40 min to rotate on its own axis
Mars Atmosphere100 times thinner than Earths95.3% Carbon Dioxide2.7% Nitrogen1.6% Argon.13% Oxygen.08% Carbon Monoxide
7Temperature RangeMuch colder than EarthTemperatures average -60 to -125 CCan reach 20 C in the summer
Composition/AppearanceRocky, thick layer of oxidized iron dust and rocksCrust volcanic basalt rockSolid Core iron, nickel, sulfurThe Red PlanetHigh iron contentDusty surfaceAppears to be red from Earth
MoonsPhobosDeimos asteroid-sized 9,377 km above Mars orbits twice a day discovered in 1877 by Asaph Hall asteroid-sized 23,460 km above Mars takes 30.35 hours to complete orbit discovered in 1877 by Asaph Hall
WaterMuch of the water escaped because of the thin atmosphere and less gravityWater contained in ice caps at north/south polesMore water is frozen beneath the surface and covered by red dust
11What would happen if a human traveled to Mars?No oxygenLow gravity; could floatHigh radiation from Sun because of the thin atmosphereVery cold temperatures
Special FeaturesTallest mountain in the solar system Olympus MonsLongest, deepest canyon in the solar system Valles MarinerisSimilar tilt and seasons as EarthDust stormsWinds over 125 mphStorms can last for weeks
