Facts about Mars
Mars is the fourth planet from the Sun that is often called the red planet. Mars is one of the most mysterious and interesting planets in the solar system. This planet can be easily detected by its reddish color seen in the night sky.
Mars is distant from the Sun by 230 million kilometers and it completes the revolution around the Sun in 687 Earth days. Days on Mars are a bit longer than Earth days. A day on Mars is about 24 hours and 39 minutes long.
Interesting Facts about Mars
Unlike our planet, Mars has 2 moons. Itís named after the fierce God of war and the 2 moons are called Deimos (Terror) and Phobos (Fear)! The satellites have irregular shape and in fact they may be seized asteroids.
Why is Mars Red?
The reason is amazing - the reddish color of Mars surface has is related to ferric oxide, also known on our planet as rust. Therefore, Mars can be called a rustic planet.
Everest is known to be the highest mountain on the Earth, and the highest mountain of the whole solar system is on Mars, and it has the name Olympus Mons. Itís about 26 km which is 3 times higher than Everest.
There is water on Mars
Perhaps the most significant fact about Mars is that it has H2O. The water is found in the form of crystallized ice. It is situated in the polar zones. As the results of the orbiters scanners show, there was time when water was flowing on Mars before it got locked up in the polar regions!
Another amazing geographical landmark on Mars is Valles Marineris, this is the largest canyon of the Solar system, it is 4000 km long, and its largest width is about 200 km.
There is No Magnetic Field on Mars
The absence of life on Mars is easily explained by the fact that it doesnít have a magnetic field. Besides the gravity on Mars is way lower that on the Earth. Without a magnetic field there is no protection from the solar radiation. The atmosphere on this planet has 95.32% carbon dioxide, this breaks almost all chances of finding life on Mars.
The Earth is Giant compared to Mars
If we compare Mars to our green planet, weíll see that Mars is a dwarf in comparison with the Earth. The mass of the Red Planet is 1/10th of the Earth mass. Mars has a denser crust however its gravity is much lower.
A lot of space missions in different forms have been sent to the Red Planet. In fact two-thirds of the missions sent to Mars have failed. Sending material weighing a kilogram to Mars costs about $309,000. Now itís easier for you to imagine how hurting a failed space mission must be. It is a real challenge for scientists and space technologists to organize a manned mission to the Red Planet.
