The Composition of Mars Atmosphere

Chemical Elements

and the Moon

The Crust: Consists of mostly Iron Oxide and mostly Basalt from Volcanic activity
The Mantle: Is a combination of silicon, iron, and magnesium
The Core: Sulfur, nickel and iron make up this layer

Quiz Time!

Question #1:

NASA already has gathered so much information on Mars, but what two major projects will they do in the future (name one)?

Question #2

Who's the person who discovered the moons of Mars? What did he name them?

Question #3

Nitrogen and Argo combined barely make up five percent of the planet, so what is the element that makes up the rest of the atmosphere and what's the percentage?

Question #4

What is the diameter of Mars and what is the size ratio between Earth and Mars?

Question #5

The person who discovered Mars is unknown, but what is the civilization that made the first records of Mars?

What make Mars Unique

More like Venus and Earth then all the other planets
The one planet besides Earth that can and could have life on it

Many believe Mars has life inhabiting the planet
It's similar to Earth giving us potential to colonize in the future
Mars has many remarkable geological characteristics

Mars is a better research topic because...

Mars is...

Possible Vacation Spot:

Time: A half an hour more in a day as well as 687 days in a year
To Bring: Extra clothes(spacesuits), soap, sunscreen and oxygen tanks
Weather: Hot in the summers and very cold in the winters
Scenery: Two moons, canals, volcanoes and canyons and frozen carbon dioxide crystals

Insight Mars Lander: Place a single geophysical lander to study its deep interior
Establish a permanent base for further study of Mars

Climate:

Future mission:

Weather: Tends to be predictable and repeats
Conditions: Wind, dust storms (some global), ice clouds and fog
Seasons: Twice as long as Earths and is the most like Earths
Temperature: At its lowest it is -225°F and its highest is 95°F; the average temperature is -81°F

Mars Reconnaissance Orbiter: Search for evidence that water existed on the surface of Mars
Mars Odyssey: Orbiter that maps the mineralogy & morphology of the martian surface.
