Here are 9 amazing facts about Mars that scientists have discovered.

1. You will feel gentle when setting foot on Mars

When humans set foot on Mars they would feel their body weight much lighter than when they were on the ground. Red planet is smaller and has less surface gravity than Earth.

Gravity on the surface of Mars is only 38% of Earth's. So if you weigh about 45kg, when you put your foot on Mars, your weight will drop to about 17kg.

In 1659, Dutch astronomer Christiaan Huygens started using advanced telescopes to observe and discover more interesting things about Mars.

One year on Mars is equivalent to 687 days on Earth, but a day here only lasts 40 minutes.

Parts of the Martian surface were taken by Mars Reconnaissance Orbiter (NASA's Mars reconnaissance orbit).

5. Mars approaches the Earth

In 2003. Mars approached closest to Earth within the past 60,000 with a distance of 55.76 million kilometers. According to NASA until 2287, Mars will once again approach very close to Earth.

6. The ice age

The ice age on Mars ended about 400,000 years ago.

7. Signs of life on Mars

In 2014, the Curiosity Rover robot explorer of the US Aerospace Agency (NASA) discovered traces of methane - an organic gas form normally produced by organisms. Since then, NASA scientists believe that the methane that appears on Mars may show the existence of ancient life outside of the earth.

8. Water on Mars

In September last year, scientists found evidence of the existence of salty summer water on the Red planet.

9. Humans on Mars

NASA is planning to create a "Independent Earth" on Mars in the 2030s. "Like Apollo programs, we are embarking on a journey to conquer space. Over the next few decades. , NASA will take important steps in establishing a human habitat on the planet. "

"We look for possibilities for people to work, study and live outside the Earth for the longest time possible. Any journey to explore Mars will lose its relative time. But we are still constantly conquering it, " NASA said.

Featured figures when referring to Mars

53%

Mars has a diameter of about 6,970km. It equals 53% of the Earth's diameter. This size helped Mars become the second smallest planet in the solar system.

38%

Gravity on the surface of Mars is only 38% of Earth's. So if you weigh about 45kg, when you put your foot on Mars, your weight will drop to about 17kg, which is much lighter than the time on Earth.

687

One year on Mars will be 687 days, but the day above will only last 40 minutes.
