Scientists have gained a lot of information by sending many space crafts to the red planet Mars. Even though most of the mysteries are solved much more are still to go. Scientists have figured out some of the interesting facts of Mars.
Mars has almost same landmass as that of the Earth but that does not consider the 71 percent of the Earth’s surface covered with water. The Martian gravity is only 37% of the Earth. That means it could leap nearly three times higher on Mars.
Mars has the tallest mountain in the solar system. Olympus Mons, a shield volcano on Mars is 21 km high and 600 km in diameter.
The average temperature on Mars is -81˚F, around 138 degrees chillier than on Earth. On Mars, the sun appears half the size as it appears on Earth. At the closest point to the Sun, the Martian southern hemisphere leans towards the Sun causing short summer and brief winter in the northern hemisphere while when at the farthest point from the Sun, the Martian northern hemisphere leans towards the sun causing long mild summer and cold winter in the southern hemisphere.
Valles Marineris on Mars is five times deeper, 20 times wider and about four times longer than the Grand Canyon.
The Martian atmosphere of Mars is 61 times thinner than Earth. It is almost entirely covered with carbon dioxide. Mars has also shown the signs of liquid water. Water was detected in the form dark stripes or strains on crater wall and cliffs. Due to Mar’s atmosphere, this water would have to be salt to prevent it from freezing or vaporizing.
Martian oceans also had tsunamis similar to those on Earth. The tallest tsunami reached till now was 400 feet long, just slightly shorter than the London Eye.
Getting on Mars is quite difficult. Only 18 missions to Mars have been successful and around one-third of them have failed. The most recent successful missions were the MAVEN mission, Mars Curiosity mission in 2012 that had arrived on September 22, 2014, and Indian Space Research Organization’s MOM Mangalyaan orbiter that arrived on September 24, 2014.
Mars also had Oasis and it is believed that if aliens would have existed there then these pools have been habitable for life.
Like Earth, Mars also has ice caps at its poles. From years, Mars has been known to have water in the form of ice. The northern cap on Mars is up to 2 miles deep.
Mars also once had oceans with 1.5 percent of all water on Earth.
The launch rate of Missions to Mars is very rare. After 23 launches in the 1960s and 1970s, only 10 of them have launched successfully.
The next launch to Mars would be most probably on March 23, 2019.
