MARSBy Will Hunter

IntroductionMars is the fourth planet in our solar system also known as the red

planet.Mars was named after the roman god of war and has been known since

prehistoric times.

Planets in order from the sun

A little bit about Mars...

Mars is the seventh largest planet in our solar system.

Mars is less than half the size of earth.Mars is very cold. The maximum temperature of

Mars is 36 C !The minimum temperature is -123 C !

Mars has deeper canyons than any other planet!The first spacecraft to visit Mars was Mariner 4 in

1965.

Min -123 c

Max -36 c

Did You Know?The deepest canyon on Mars would stretch from New

York toLos Angeles on earth!

Mars Atmosphere

Mars has a atmosphere mostly made up of carbon dioxide

(95.3%) andalso has a bit of nitrogen

(2.7%).The rest are made up of a few other gases. (argon ETC.)

FUN FACTS

Vikings 1 and 2 were the first space probes to successfully land on the surface of Mars.

The probes analysed gases in the Martian atmosphere and chemicals in the soil for evidence of life.

They also measured wind speed, wind direction and more.

It takes 686.98 days for Mars to orbit the sun. One rotation on Mars takes 24 hours and 37 minutes.

The distance from the sun is 229 million km.

Mars orbit takes it inside an asteroid belt.

If you weighed 32kg on Earth you would weigh 12kg on Mars.

SPACE PROBES

The MoonsMars has two moons named Phobos and Deimos.Phobos is so close to the surface of Mars in 50 million years it will crash down onto Mars or break up into a ring around the planet.

The layers of Mars are the crust, mantle and core.The crust is about 50 km thick.The core is the middle part inside of the planet measuring about 3,000 km in diameter including possible solid inner core.The mantle transports heat generated during accretion and subsequent core formation.

Diameter and Circumference

This information is about the diameter and circumference of Mars.

The circumference of Mars is 21343km while the diameter is only 6794km.

21343km

MARS ROVERS

The Mars Rovers landed on separate sides of Mars.

They weigh 174kg and are 1.5 metres high.They are 2.3 metres wide.

They have 6 wheels that are designed to coil and uncoil to absorb shocks as they move across the ground.

Using 2 antennas they can communicate with Earth.

The rovers are designed to travel 100 meters a day but are normally less because they stop to observe stuff like the atmosphere and soil.

They are designed to survive ninety days on Mars.

I think Mars is a great planet to research because it is interesting.
