Let's take a look on Mars
Mars
The fourth planet from the sun in Solar system.Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. Mars’ rotational period and seasonal cycles are likewise similar to those of Earth. Mars is the site of Olympus Mons, the highest known mountain in the Solar system.
Olympus Mons
Earth, having about 15% of Earth's volume and 11% of the mass.
Its surface area is only slightly less than the total area of Earth's dry
land. While Mars is larger and more massive than Mercury,
Mercury has a higher density. This results in the two planets having a
nearly identical gravitational pull at the surface—that of Mars is
stronger by less than 1%. Mars is also roughly intermediate in size,
mass, and surface gravity between Earth and Earth's Moon (the
Moon is about half the diameter of Mars, whereas Earth is twice;
the Earth is about nine times more massive than Mars, and the Moon
one-ninth as massive). The red-orange appearance of the Martian
surface is caused by iron oxide, more commonly known as
hematite, or rust.
Can we live on Mars?
Mars is not as close to Earth as Venus is, but it probably is the only planet in our solar system that we can colonize. But living there won’t be simple.
Mars is poorly suited for human habitation. There’s some ice at the poles and perhaps some water in underground repositories. Gravity is only 38 percent as strong as on Earth. The atmosphere is thin and consists mostly of carbon dioxide (95%). So colonists would have to either take air from Earth or make air on Mars. Plants efficiently separate the oxygen bound to carbon and therefore can make air we can breathe, so colonists should take plants along.
The Martian atmosphere is too thin to hold oxygen, which would just escape to space. So the plants would have to be cultivated in greenhouses and the oxygen they produce kept in flasks.Mars has a very weak magnetic field, and its atmosphere offers little protection against radiation from space. So the Martian colonists would have to build radiation protection into their houses and wear thick suits. Unlike Earth, where most incoming meteorites burn up in the atmosphere, many meteorites crash dangerously onto the surface of Mars.
The Martian weather is awful. It’s cold: the average temperature of the southern hemisphere is minus 60 degrees Celsius; even at the equator, it’s seldom over zero. Winds are fierce and blow at speeds of several hundred kilometres an hour, and storms can last for months. The wind whirls up fine dust that penetrates everything and sticks to all surfaces, which literally would toss sand in the gears of vital mechanical and electronic equipment.
Today, there are no concrete, approved plans for sending people to Mars. The earliest date mentioned in official papers is 2019, which would be 50 years after the first Moon landing.
Do you want to go to MARS?
I presented my report on the first week of the presentation.
I was very worried at first, but it went well.
I presented about the planet called Mars, based on the information that i researched on we can noticed that we can on Mars but to live on Mars we need to built a dome of oxygen so we are able to live on Mars.
