btn #15 Mars Experiment

Understanding

Scientists are running experiments to see how people would act if they were going to Mars or are on Mars. These experiments are run in a white dome next to a volcano in Hawaii maybe to recreate the temperatures of mars. But the experiment is an isolation experiment, so if they want to leave the 11m dome they have to where a space suit. But the experiment was pretty much done to see if 6 people could last a year with almost identical conditions of Mars.

Why did the scientists choose to do the experiments next to a volcano?

Would this experiment effect the possible outcomes of us going to Mars in the long run? 

My understanding is that scientists are doing experiments in a dome and its to see if people would last on Mars.

We live the milky way in the solar system that is over 4 1\2 billion year old place that travels around the galactic center at 200,000km per hour, and also circles it every 250,000,000 years. We circle a star that’s in the center of our solar system called the sun and 8 planets circle it, and the 8 planets are divided into 4 groups, terrestrial planets, Mercury, Venus, earth and Mars and 4 gas giants which include, Jupiter, Saturn, Uranus and Neptune. Mercury is the the smallest and lightest planet and does not have any moons, Venus is 1 of the brightest planets in our solar system and is the hottest planet and the out of control temperatures there mean that it never cools under 430 degrees c and has no moons. Earth is our planet and is the only planet with temperatures that are nice enough to allow us to have liquid water and the only place that life is know so far, and the earth owns 1 moon. Mars is the second smallest planet in our solar system and hardly big enough to keep a very thin atmosphere the Olympus Mons largest mountain known in our solar system, Mars has 3 small moons. Now onto gas giants, Jupiter is the largest planet in our solar system and is the place were the largest storm that we know of, the great red spot and Jupiter has 67 moons. Saturn is the second largest planet, Saturn is know for the extra large rings and has 62 moons. Uranus is the 3rd largest planet and is 1 of the coldest planets unlike all the other planets Uranus’s axis is tilted like earth and has 27 moons. Neptune is the last planet in the solar system and is pretty much the same and Uranus and has 14 moons.

The sun creates enough energy to be able to keep us warm and to satisfy man kind for many more years to come except for the day when the sun melts the crust of our planet wiping out the entire population until the sun perishes into nothing in the galaxy but thats in over 1 billion years. Then man kind will then be extinct until we find a new planet to call come.

Why does it have to be our solar system that has to get destroyed?

Will the galaxy ever get destroyed?

My understanding is that there are 8 planets 4 gas giants and 4 planets and 1 day out solar system will be gone forever.

There was excited news at Nasa when they successfully launched a rover called Curiosity onto Mars in the year 2012. A group of highly trained and professional group of scientists successfully landed Curiosity onto the surface of Mars which was hopefully going to change our knowledge about Mars forever. Curiosity is a rover the size of a car and is equipped with all sorts of technology attached to him. But the way they got this rover to Mars was an 8 month trip and the 7 minutes of terror, the 7 minutes of terror was the most interesting and scary thing that happened because the rover had to slow down from over 20,000 kays to 0 in just seven minutes thats were it got its name. The way they landed the rover was with a little shuttle that was holding it but it really got onto the surface with a para-shoot and jet pack type things on the bottom of the rover making an extremely cool landing. 

There are many reasons why curiosity was launched to Mars but one of them was to look at the surface and examine traces of life and water it also looks for radiation signs, because scientists are hoping in the near future to have people live on Mars.

How did the little pod that was holding keep all its gas that makes it fly inside because it didn’t look like there was a lot of room in the little pod?

 How did the pod survive the toxic layer around earth?

My understanding is that there is a rover up on mars which has been there for 7 years examining to surface and taking samples so we can hopefully build life & civilization on Mars because of the water signs and the air.

Greeks – teal

Maya – pink

Babylonians – purple

Hypotacus was believed to be the best astronomer, He created trigonometry, he documented thousands of stars and created something called ‘Precession of the Equinoxes’ which was a term for the earth wobbling around on an axis. Which is used to predict that in 10,000 years the north star will be Polaris. 

The Maya are a group of mesoamerican Indians made a calendar that was called ‘the long count calendar’ and it was based on the base number 20. But we don’t know much about the Maya because all their studies were burned by Spanish  conquestidores.

The Babylonians were very advanced in their studies because they had a great writing system. So they were able to write down large amounts of math and stuff about stars which they used to make calender’s but with the base 10 system, which they used to time important things. They also used them to predict astronomical phenomenons. It was also the place were forms of modern horoscopic astrology was formed.
