Facts about Mars (part 2)
Mars contains the largest labyrinth of intersecting canyons in the solar system called the Noctis Labyrinthus (“labyrinth of the night”).
Mars has the largest and most violent dust storms in our entire solar system. These storms often have winds topping 125 mph, can last for weeks, and can cover the entire planet. They usually occur when Mars is closest to the sun.
Only 1/3 of spacecrafts sent to Mars have been successful, leading some scientists to wonder if there is a Martian “Bermuda triangle” or a “Great Galactic Ghoul” that likes to eat spacecraft.
In 1976, Viking I photographed a mesa on Mars that had the appearance of a human face. Many individuals and organizations interested in extraterrestrial life argued that intelligent beings created the “Face.” Though the Mars Global Surveyor (1997-2006) revealed that the “Face” was likely an optical illusion, believers in the “Face” charged NASA with stripping data from the new image before it was released to the public.
Mars has an enormous canyon named Valles Marineris (Mariner Valley) which is an astounding 2,500 miles long and four miles deep. As long as the continental United States, this gigantic canyon was likely formed by the tectonic “cracking” of Mars’ crust and is the longest known crevice in the solar system.
During the Renaissance, Mars place a central role in one of the most important and fiercest intellectual battles in the history of Western civilization: whether the earth was the center of the universe. Nicholas Copernicus (1473-1543) coherently explained that Mars seems to move backwards across the sky because Earth overtakes Mars in its orbit around the sun.a
Mars was formed about 4.5 billion years ago and is about 4,000 miles wide (half the diameter Earth). Because so much of Earth is covered by oceans, the amount of land surface of the two planets is nearly equal.e Mars is also much lighter than Earth: only 1/10 of its mass. It’s the fourth planet from the sun and is the last terrestrial (rocky) planet (the outer planets are all gaseous).
The Earth environment most closely resembling the current conditions of Mars is of the Antarctic deserts. However, even the most hostile environments on Earth are far more suitable for life than the surface of Mars.
Mars’ crust is thicker than Earth’s and is made up of one piece, unlike Earth’s crust which consists of several moving plates.
Although it is much colder on Mars than on Earth, the similar tilt of Earth’s and Mars’ axes means they have similar seasons. Like Earth's, Mars’ north and south polar caps shrink in the summer and grow in the winter. In addition, a day on Mars is 24 hours 37 minutes—nearly the same as Earth’s. No other planet shares such similar characteristics with Earth.
