Red Planet Mars
Mars Is That The Fourth Planet From The Sun And Also The Second-Smallest Planet Within The Solar System After Mercury. Mars Is Often Referred To As Red Planet. Mars Is A Planet With Full Of Dust, Cold, Desert World With A Thin Atmosphere. This Dynamic Planet Has Seasons, Polar Ice Caps, Canyons And Extinct Volcanoes, Evidence Of An Even More Active Past.

A Year On Mars Lasts 687 Earth Days

A Day On Mars Is Not Much Longer Than A Day On Earth, Lasting 24 Hours 39 Minutes 25 Seconds. A Martian Year, However, Is Far Longer Lasting 687 Days. That Means Seasons On Mars Are About Twice As Long As They Are On Earth, And Because Mars Orbit Around The Sun Is Oval, Seasonal Variations Between Winter And Summer Are Far More Severe Than Those On Earth.

At The Equator, The Temp... Reaches About 86°F; At Night It Can Plunge To -284°F

Mars Gets About 60 Percent Of The Sunlight We Experience On Earth. Meanwhile Landing Near The Equator On Mars Would Allow Astronauts To Take Advantage Of Mild, Pleasant Temperature During Daylight Hours. But At Night, It Can Easily Reach -284ยบF So Structures Would Have To Be Specially Designed To Insulate Astronauts From The Cold.

Plant Can (Probably) Grow In An Environment With 1/10th The Atmospheric Pressure Of Earth

The Martian Terrain Look A Lot Like Certain Parts Of Earth – The Dry Valley Of Antarctica Or The High Deserts On Hawaiian Volcanoes. Astronauts Could Use Inflatable Greenhouse To Grow Food; Estimates Of The Pressures Needed Inside A Martian Greenhouse Vary, But Botanists Expect To Be Able To Grow Plants In Environments That Certain About 1/10th The Atmospheric Pressure On Earth.

We Don’t Know What Effect The Gravity Will Have On The Plants Themselves.

There Are More Than A Million Cubic Miles Of Water On The Surface Of Mars – Almost All Of It Is Ice

If The Temperature On Mars Could Be Raised, That Would Release Frozen Gases That Would Boost The Atmosphere And Create A Greenhouse Effect. Surface Ice Would Melt, Especially Near The Equator, And Water Would Flow, Allowing Settlers To Grow Plants Outside Of Greenhouses. Those Plants Would Then Add To The Oxygen Content Of The Atmosphere.

Mars Atmosphere Is Made Up Of 95% Of Carbon Dioxide

Oxygenating Mars Atmosphere Could Be A 1000-Year Plus Job. The Air Human Breath On Earth Is About 21% Oxygen And 78% Nitrogen; That Mix In Crucial. Less Oxygen And We Turn Blue; More Oxygen And We Damage Our Lungs. The Nitrogen Doesn’t React With Our Lungs But Makes Up The Vast Majority Of What We Breathe To Ensure We Get The Oxygen Levels We Need. This All Means We Not Only Have To Find Enough Oxygen To Pump Into Mars Atmosphere, Which Is Currently 95% Carbon Dioxide, But We Also Have To Displace Most Of That Carbon Dioxide With An Inert Gas. To Complicate Things Further, We Will Then Also Have To Compensate For The Planet-Cooling That Will Occur With Less Carbon Dioxide Around.

Don’t Phone Home; There’s No Point

When Earth And Mars Are Farthest Apart, In 21 Minutes For A Radio Signal To Get Back To Earth. Unmanned Spacecraft Must, Therefore, Use Artificial Intelligence Software To Make Decisions In Emergencies, Because There Is No Time To Call Home For Help.
