MARS
FACT AND DISCOVERIES
FACT
- 4th planet from the sun
- Second smallest planet in the solar system
- Day length: slightly under 24h
- 2 moons: Deimos and Phobos
- Surface temperature: -87*- 5*

For hundreds of years ago,when the sun and the moon where the only visible things seen in the sky,expect for a red dot(Mars) they didn't know what it was and the dot became a frustration. To name it, they thought of something that was a frustration.
NAME
- From the god of war, frustration
- Mars
- Got it because of it's red surface
- Also called " the red planet
- Moons the gods brothers

EARTH&MARS
- Differences in size, temperature& atmosphere
- Canyons, volcanoes& impact basins like the ones on earth
- The dry surface area is almost the same
- Because 2/3 of the Earth's is oceans
- Their is a difference of 1.55* on the tilt of the axis
THE STUDY OF MARS
- Mars may be able to carry life on it in the future
- We want to study Mars because the Earth&Mars comes from a proto planetary cloud
- We're humans and we want to know if we're all alone
- in the universe& if there is anywhere their might be life anywhere else
- Global warming
EXPLORING MARS
ROVERS
- 4 successful rovers
- Nasa project
- Mission: to find a trace of life
- "Mariner 4" 1964
- Hard to land on Mars
DISCOVERIES
- Several successful discoveries
- Jelly doughnut, "Star Trek" symbols, lizard
- "Blueberries": 10 years ago, puzzle ever since
- Marble size, dark blue colour, blueberry
- Sign of water, as well as water patterns
WATER ON MARS
- 3.8 billion years ago Mars was warmer and wetter
- Atmosphere, warmer temperature
- Gullies created from rain, snow melt( for example) or the groundwater
- Canyons could have been carved out of rain
- Minerals support the discovery of water
TERRAFORMING MARS
- To terraform Mars, we need to know hey it cooled down and if there has been life on Mars
- There is evidence that Mars had a thicker atmosphere and that it was a warmer planet
- Where did all the carbon dioxide and oxygen go? Is it "hidden" in the volcanos or is it in space
- Technology says it is possible to create global changes on Mars
- Just raising the atmosphere's pressure and surface temperature alone will take a few decades
GREENHOUSE EFFECT ON MARS
- The greenhouse effect on Mars is very low compared to the Earth because,
- Mars has a thin atmosphere and therefore have a low greenhouse effect
- What helped Mars to keep it warm was large amount of hydrogen "hidden" in the volcanos
- Where did the hydrogen go, so Mars cooled down?
