    MARS

 

Mars is the considered the God of war as the Romans and the Greeks thought of the planet. It's also referred to as the "Red Planet" because of its reddish appearance due to iron oxide. The color that is seem from Mars explains the reason for the Romans and the Greeks for naming Mars the God of war because of its reddish color, which stands for blood.

 

 

 

Basic Facts: 

 

  • Mars is the Fourth planet in our solar system.
  • It's diameter is 1/2 than that of Earth.
  • Has a rotation period of 24 hours 40 min.
  • Mars has a tilt of 25.19 degrees, similar to Earth's tilt (23.44 degrees), which is thought of to cause seasonal changes in Mars' weather. 
  • Mars has layers of rocks that looks like waves. These waves happen because every 100,000 years a new layer would appear ontop of the other.

  • Geology of Mars consists of giant colcanoes (olympus Mons), valleys which are free of ice, impact craters, and reddish deserts of brocken rock.

 

 

Olympus Mons is the highest and largest volcano in the solar system.It rises about 25 kilometres above the surrounding surface; its actual height is closer to 27 kilometres, since it stands in a 2 km deep depression. Its height is about three times that of Mount Everest. Its base is more than 550 km in diameter and it is surrounded by a cliff 6 km tall. Measurements of Olympus Mons are only estimations; they were calculated by examining the pictures taken by the spacecraft Mariner 9 in 1971.

 

Atmosphere on Mars:

¨  Mars has a very thin atmosphere which contains mostly of carbon dioxide (CO2)

¨  It has seasons similar to Earth which causes growth and shrinking of polar ice cap

¨  The atmosphere on Mars consists of 95% carbon dioxide, 3%nitrogen, 1.6% argon, and contains traces of oxygen and water

¨  Martian surface temperatures vary from lows of about −140 °C (−220 °F) during the polar winters to highs of up to 20 °C (68 °F) in summers.

 

 

   

 

Water on Mars:

 

  • If liquid water once flowed on Mars, then its climate must have been different in the past.
  • The atmosphere of Mars must have been thicker long ago before much of the gas had time to leak away.
  • Today, however, we would not expect to find liquid water on Mars. The atmospheric pressure is too low to keep it from boiling away to vapor.
  • Sophisticated measurements suggest taht significant amounts of water are hidden in the crust.

Experiment One:

 

Develop a mission to Mars which will work on finding life on Mars. We plan to continue looking for more fossils in the Mars’s ice cap. Examination of ice might provide with any kind of fossil and past signs of water. These findings would be a first step toward learning whether the ground on Mars is hospitable, because all life as we know it requires water.

Experiment Two:

We plan to send a human to Mars by the end of 2030. First trained astronauts will be sent to the moon to test and prove the technologies necessary to send humans "beyond". The moon will be our pit-stop to the way to Mars. Having astronauts traveling ontop of Mars can enable us to find better minerals for testing. Astronauts can dig better and can offer an on-site experience unlike a probe, when finding minerals to examine for life forms on Mars.

 

 

 

 

 

 

 

 

                          

 

Additional Experiments:

Our other experiment would be to study the interior of Mars since the relative size is unknown. We would place motion sensors caused by seismometers on the surface. This instrument will measure the tiny movements of the surface and scientist would use the measurements to learn what lies beneath. Another experiment would be to drill a hole in the ice caps to find any kind of fossil that can contribute to a new discovery.

 

Equipments:

1.) ProbeWe will develop a suitable probe which will be engineered to drove longer distances over rougher terrain than previous rovers, and will have more advanced research instruments. The bestthing would be to have a trained field geologist witha rock hammer to look for fossils since a human explorer would offer on-site experience, better mobility(presumably he would have his own rover to drive around in), and a much better chance of finding evidence of life. In the end the best way to settle the debate is to send people to Mars. 

2.) Suitable Space Suit- Develop appropriate suits which will with stand extreme temperatures and gravity on martian surface since Martian surface is only about 36% than that on Earth.

It's not that the moon being a pit stop is a bad idea, but seems senseless as the distance is still far. The idea is still nice though, like livin on the moon before living on mars.

I think the information needs to be organized better, and I believe more details on the experiments would also be nice. Specifically you said you wanted to study the interior of Mars, but what kind of equipments will you need?

very unique organization.. but maybe more experiments and detailed intrstructon.. overall, it looks good

I agree with Grace; you could have organized your information better for it would make looking for stuff a little easier. Also, for the experiments section, you could have been more detailed in terms of the materials (like what would you use for the suits and probe) and in other areas. By the way, a couple of the pictures don't seem to be working.

I like the images, unfortunately I believe some of them do not show up. Also, I believe that your information could be organized better.
