Slide3: 

By Taylor O’Brien And Nick Ricca Based on the theory of evolution and the patterns of biology, life on Mars will soon be an extreme possibility. As it is now and was in the past, the environment and atmosphere was and still is unstable to support any life. Now that the planet is warming up, bacteria and other single celled organisms will soon be able to live and then will soon evolve into multi-celled organisms. Billions of years in the future, a life form as advanced and evolved as humans may be formed. Yet nowhere in the past or present have the conditions of the atmosphere and the environment permitted any form of life to live.

Slide4: 

The first life on Earth formed in a climate that Mars doesn’t have. One thing Mars’ lacks is warm water. Mars’ atmosphere today is compared to Earth’s atmosphere billions of years ago. However, it will take thousands of years for any form of life to produce. Below is the Martian “face” which is really just a hill.

Slide5: 

Bacteria and other unicellular organisms were the first life forms to appear on Earth. Scientists think that they helped shape the environment, eventually creating atmospheric oxygen that enabled more complex life forms to develop. Since Mars is warming up we believe there will be a more stable environment for bacteria to form.

Slide6: 

Darwin’s theory of evolution shows that as time progresses organisms slowly evolve and adapt to their environment. However, in order to allow this to begin, a stable environment and an permissible climate is needed. Mars’ climate and environment do not meet these requirements.

The Layers on Mars: 

The Layers on Mars Mars is layered, but the layers are not all the same physical properties. Craters and eroded surfaces show at least four distinct layers of rock. By Cassie Schneider & Skylar Sparks

Oh my a lake on Mars: 

Oh my a lake on Mars Geologist have discovered a large former lake on Mar’s highlands that would cover the size of Texas and New Mexico combined, and overflowed to carve one of the planets largest valleys. The flood channel, Ma’adim Vallis, is more than 550 miles long and up to 6,900 feet deep, making it larger than Earth’s Grand Canyon. Using instruments on NASA’s 2001 Mars Odyssey spacecraft, scientists found enormous quantities of buried treasure just under the surface of Mars-enough water ice to fill Lake Michigan twice over. And that may just be the tip of the iceberg. The ice has been calculated at about 50% water-ice!

Why is the Red Planet Red?: 

Why is the Red Planet Red? Mars is red because of the ferric dioxide in it’s soil. This is commonly known on Earth as “rust”. There are many volcanoes on Mars, although we have never seen on erupting. It is an open question as to whether these volcanoes are extinct or just dormant for now. Mars includes the largest volcanoe in the solar system. Olympus Mons is 27 km high and 600 km across. Wow!

Mar’s Magnetic Field: 

Mar’s Magnetic Field Rather than Mars having a weak, uniform magnetic field, measurements taken as the spacecraft continued to dip into the atmosphere, slowing into its parking orbit, revealed scattered magnetic-field sources which, in pockets where they exist, are stronger than expected. Leading scientists to conclude that Mars’ core long ago ceased the dynamics that generate dipolar planetary magnetic fields, and that the diffuse magnetic core materials the space craft is detecting lie in the crust close to the planet’s surface.

Current Atmosphere of Earth and Mars.: 

Current Atmosphere of Earth and Mars. Earths’ Atmosphere Moist Climate Average temperature is 15 degrees Celsius Contains 1013 millibars of atmospheric pressure Atmosphere contains 78% nitrogen, 21% oxygen, 9% argon, .03 carbon dioxide, and many others. Mars’ Atmosphere Very dry climate. Average temperature is -60 degrees Celsius. Contains 6 millibars of atmospheric pressure. Atmosphere contains 95.3% carbon dioxide, 2.7% nitrogen, and 2% of other gases. By Flannery Wheeler and Danielle Wood

Why Mars Never Had Life: 

Why Mars Never Had Life No one has found any fossils from Mars. Mars doesn’t contain water in the liquid form, which organisms need to live. The gravity is too weak to hold an atmosphere that will sustain life. By Flannery Wheeler and Danielle Wood

Mars’ Climate Problems for Present Life: 

Mars’ Climate Problems for Present Life Mars has no accessible liquid water. It has a weak gravity. Has a very thin atmosphere that wouldn’t sustain life. Very severe weather hazards such as dust storms, hurricanes, etc. Also, it has a very cold temperature. By Flannery Wheeler and Danielle Wood

Possibility of Future Life on Mars: 

Possibility of Future Life on Mars In the sun hydrogen is made into helium. As time passes the helium builds up and causes the fusion process to expand in search of free hydrogen. Because the sun is growing, human life on Earth will become impossible. On Mars, however, the closer sun will cause the water to melt and the temperatures will heat up. The climate will become warmer and wetter with the expansion of the sun In a sense, Mars will become the next Earth for a brief time. We believe a species with adaptations to the harsh weather may form. By Flannery Wheeler and Danielle Wood
