1. The Egyptians gave Mars its first recorded name: Har dècher (“The Red One”). The Babylonians called it Nergal (“Star of Death”). The Greeks and Romans named the planet after their respective gods of war, Ares and Mars. The Hebrews called it Ma’adim, or “the one who blushes.” Many ancient people believed the reddish color came from actual blood on the planet.
2. The month of March is named after Mars.
3. The symbol for Mars looks like a shield and a spear from the war god Mars/Ares. It is also the symbol for the male sex.
4. The ancient Greeks thought the Earth was the center of the Universe and that Mars was one of the five traveling stars that revolved around the Earth.
5. Egyptians called Mars the “the backward traveler” because Mars appeared to move backwards through the zodiac every 25.7 months.
6. Mars’ red color is due to iron oxide, also known as rust, and has the consistency of talcum powder. Literally, the metallic rocks on Mars are rusting.
7. The atmosphere (mostly made up of carbon dioxide) on Mars is so thin that water cannot exist in liquid form—it can exist only as water vapor or ice. Liquid water is considered for many scientists to be the “holy grail” of Mars
8. No human could survive the low pressure of Mars. If you went to Mars without an appropriate space suit, the oxygen in your blood would literally turn into bubbles, causing immediate death
9. If you were driving 60 mph in a car, it would take 271 years, 221 days to get to Mars from Earth.
10. Mars lacks an ozone layer; therefore, the surface of Mars is bathed in a lethal dose of radiation every time the sun rises
11. Mars contains the largest labyrinth of intersecting canyons in the solar system called the Noctis Labyrinthus (“labyrinth of the night”)
12. 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.
13. 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
14. 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
15. 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.
16. 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.
17. 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).
18. 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
19. Mars’ crust is thicker than Earth’s and is made up of one piece, unlike Earth’s crust which consists of several moving plates.
20. 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
When you do the math, the density of Mars is 3.94 grams per cubic centimeter (g/cm^3).
In comparison, the Earth is the densest planet in the Solar System, with an average density of 5.52 g/cm^3.
Arbitrageur: And despite the mass of Mars only being 10% that of Earth, you would weigh 37% as much on Mars as you do on Earth. That's seems like relatively strong gravity for such a small mass.

That puzzled me for a minute, too, until I remembered the formula for gravitational force. In addition to the mass of the planet, it also includes the radius of the planet (squared), and since Mars is smaller, you are closer to the center than you are on Earth.
30.Mars has 37.5% of the gravity that Earth has. This means that a 100-pound person on Earth would weigh only 38 pounds on Mars and could jump three times as high.a

The results contradict each other.
What can I tell my friends ? Am I heavier or lighter on Mars ?

if you research they now believe there is no chance it is naturally made
