Several countries, including India and the United States, are continually working on their mission to Mars to explore the potential for living and to look for signs of life on the Red planet. Earlier this month, the National Aeronautics and Space Administration safely landed its Perseverance rover in the Jezero Crater, proven to be an ancient lake bed created billions of years ago.
According to Nasa’s Mars exploration program, the crater filled with water to form a deep lake, which dried up as the planet’s climate changed. A persistence rover will be used to study the rocks of the lake’s old bed and return samples through future missions. While it is too cold and dry for life to exist today on the Martian surface, people want to know if there has ever been life on the Red planet.

How does Mars Compare to Earth?
Earth’s atmosphere is mostly made up of nitrogen and oxygen and Martian atmosphere is mostly carbon dioxide. Earth has only one moon, the natural satellite that revolves around the planet, and Mars has two moons – Phobos and Deimos – that are very small in size compared to Earth’s moon.
It would take more than six identical Mars to fill the size of the Earth, which also affects the gravitational force seen in the Martian atmosphere. If a person weighs 100 kilograms on Earth, the individual would be about 38 kilograms on Mars, since the gravitational force on the Red planet is 0.375 times Earth.
While scientists are still studying the exact structure of Mars, the heart of the Red planet may be similar to those of Earth, according to Nasa. Martian atmosphere is 99 percent thicker than Earth and has an average temperature of -81 degrees Fahrenheit, very low compared to Earth’s temperature.
