write an essay on All about mars
Answers
Like Earth, Mars has differentiated into a dense metallic core overlaid by less dense materials.[37]Current models of its interior imply a core with a radius of about 1,794 ± 65 kilometers (1,115 ± 40 mi), consisting primarily of iron and nickel with about 16–17% sulfur.[38] This iron(II) sulfide core is thought to be twice as rich in lighter elements as Earth's.[39] The core is surrounded by a silicate mantle that formed many of the tectonic and volcanic features on the planet, but it appears to be dormant. Besides silicon and oxygen, the most abundant elements in the Martian crust are iron, magnesium, aluminum, calcium, and potassium. The average thickness of the planet's crust is about 50 km (31 mi), with a maximum thickness of 125 km (78 mi).[39] Earth's crust averages 40 km (25 mi).
Surface geology
Main article: Geology of Mars
Mars is a terrestrial planet that consists of minerals containing silicon and oxygen, metals, and other elements that typically make up rock. The surface of Mars is primarily composed oftholeiitic basalt,[40] although parts are more silica-rich than typical basalt and may be similar toandesitic rocks on Earth or silica glass. Regions of low albedo suggest concentrations ofplagioclase feldspar, with northern low albedo regions displaying higher than normal concentrations of sheet silicates and high-silicon glass. Parts of the southern highlands include detectable amounts of high-calcium pyroxenes. Localized concentrations of hematite and olivinehave been found.[41] Much of the surface is deeply covered by finely grained iron(III) oxidedust.[42][43]
Answer:Since my childhood I had a dream to travel through space, as I always wanted to live on Mars and heard lot about it in news and from other sources. Mars was named by the Romans for their god of war because of its red, bloodlike color. In my teen age along with studies of science my keen interest was developed in astronomy and start reading many books on it. I came to know that Mars is also known as the Red Planet and Earth’s closest neighbor yet 35 million miles away. It is the only planet seems to have the most potential out of all the other planets to support human life. A journey to Mars could take around four to six months, but scientists are unsure of how the health of human beings would be affected during this sort of journey.I used to chat with my friends a lot on my wish to travel to Mars. In my dreams many times I saw myself on Mars exploring the Planet and talking to Martians. Here I am with my trip to mars imaginary through. Space travel is somewhat like an air travel. Ichecked in with my luggage and boarded the ZX-2020 Space Shuttle which has cozy beds, a dining area and a recreation section too. After blast-off, the ride was smooth and we are going with 50 times the speed of sound. The earth was getting smaller and smaller which was little scary. After the long journey of seven days, we finally landed on the planet Mars. We were taken in a space mobile to the Cosmic Hotel which looked like a big steel box from the outside but it was like a luxury hotel inside having all the facilities and modern amenities.I wanted to explore each and every inch of the planet so I wear my space suit as the Martian atmosphere is made up mainly ofcarbon dioxide. It was extremely cold and almost impossible to survive in this cold without a spacesuit. So I had to wear spacesuit all the time. Mars surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. Mars is known as the Red Planet. It gets its red color from the iron oxide (like rust) in its soil. The highlight of my Mars trip was flying a space mobile though I did not see any sign of life there but had clouds and wind just like Earth. Mars has two small moons, Phobos and Deimos, that may be captured asteroids. Mars was indeed spectacular! Soon it was time to return to Earth. I was happy to have visited Mars.I am eagerly waiting for my dream to come so that I can live my dream in real.this planet is so stranse and new to me i was really amazed to see new creatures around me .one of them came to me and said some thing which i did not understood it was a strange language ....everyone gathered around me and where looking at me asif i did any crime but after an hour or so they got friendly to me .... they hay 2 head 6 fingers 4 legs 10 eyes 2 lips 4 nose i was just confused when i saw them earlier i was also scared but then slowely i felt comfortable but suddently something happened a small baby alien came to me and touched my hand .... he was very innocent and cute and suddently he vanished then i saw that there was a war going .
