Top 10 exciting facts about Mars
Humanity has always been interested in the question: “Is the Earth the only planet where life exists?”. Several generations of scientists are engaged in research on this issue, and one of their main objects is Mars.
The secret of a close neighbor
Mars, that's the name of the god of war in ancient Rome, in his honor and was named this mysterious planet. It is the fourth distance from the Sun, and the seventh in size, making up a little more than a tenth of the Earth.
A long study of the features of this cosmic body each time confirms the hypothesis about the possibility of the existence of living organisms there. But from this mass of information, we have selected for you 10 of the most interesting and exciting facts.
- Colour. Due to the bright, even aggressive color, Mars still bears the name of the Red Planet. The researchers found that the reason for this “color” lies in the high concentration of iron oxides, which in the form of dust cover the entire planet.
- Temperature. To survive here, perhaps, only the most enduring forms of life, because such extreme conditions do not suit everyone.In summer, for example, closer to the equator, the temperature reaches +20 degrees, but at night it drops sharply to -80 and even -90 degrees.
- Attraction. Its strength is only 38% of the earthly index we are used to. That is why an astronaut with a weight, for example, 50 kg, will weigh only 19 kg on Mars, which will make it possible to make light high jumps to record distances.
- Atmosphere. Without special equipment and clothing, no one person could be on the planet. The atmospheric pressure there is so low that oxygen contained in the blood would immediately go into a gaseous state, which causes instant death.
- Radiation. The rising sun each time carries a huge and deadly dose of radiation for Mars. And all due to the fact that there is no ozone layer on the planet, which serves as protection from active sunlight.
- Time. In a day on Mars 24 hours 37 minutes and 23 seconds, and the year is longer than the Earth almost twice.
- Satellites. Their names are quite in line with the name of their "owner" - Deimos and Phobos, which in Greek means "panic" and "fear." Deimos makes a full rotation in 1 day, and Phobos needs 2,7 days to do this.
- There was water on Mars. This fact is confirmed by numerical meanders - the remnants of the channels of dried rivers.Also scientists have been found mineral rocks, which could appear only if there is water.
- Storms. Despite the rarefied atmosphere, dust storms often occur on the Red Planet, with wind speeds of up to 200 m / s. Their duration can stretch even for several weeks. Most often this happens during periods when Mars passes as close as possible to the Sun.
- The highest point. Volcano Olympus is the highest point in the entire solar system, rising to 27 km. Expeditions of rovers and soil tests suggest that some remnants of lava are relatively young, which means that the volcano may be active.
Above all, the features of the relief and structure of the earth's crust give the opportunity to anyone who wants to see on Mars the similarity of pyramids and mystical hills, which from a height resemble a human face.
Scientists do not stop trying to discover all the new amazing facts about the Red Planet, and who knows, maybe soon we will learn about it a lot more interesting and exciting.
