The Earth has been the most convenient planet for humanity for thousands of years, together with its atmosphere, soil, drinkable water springs, and gravity. All of these have helped the Earth become our home. However, we are unfortunately incapable of protecting the Earth as it protects us from the dangers of space. Due to the damage and extravagant use of the valuable resources of Earth, we have become more interested in space travel and finding a habitable place in space, as in the case of most science fiction movies. Even though the research done so far has not found a future home, at least in our solar system, the recent explorations by the rovers called Curiosity and Perseverance interestingly show that there might have been life on Mars or that Mars might have been a habitable planet thousands of years ago because they discovered some strikingly similar features between the Red Planet Mars and our current home Earth, and this post is going to discuss those similarities in the following by taking you on an interesting journey to Mars. So, enjoy the ride!
1. Size
Mars is the fourth planet from the Sun, and it is much smaller than the Earth—almost half its size. Although it is much smaller than Earth, one Martian day (24.6 hours) is recorded to last almost the same length as a day on Earth.
2. Temperature and Climate
Similar to Earth, Mars also has an atmosphere, but this atmosphere is much thinner (around 100 times) than the one on Earth. Therefore, Mars cannot retain heat energy as much as Earth does. In spite of its thin atmosphere, the temperature on Mars can go up to around 20 °C on a summer day, which is an ideal temperature for the human race to survive. However, this number can drastically decrease to around -75 °C during the night, which is even colder than the temperatures recorded around the poles of Earth. However, there are still some places on Earth as well whose temperatures go below that number, such as Dome Fuji (-93.2°C, Antarctica); Vostok Research Station (-89.2°C, Antarctica); Dome Argus (-82.5°C, Antarctic Plateau).
3. Geography
Although there is no life on Mars today, Mars can still be considered a dynamic planet, with its seasons, polar ice caps, canyons, and extinct volcanoes.
Even though it has been known as the Red Planet by humans, Mars has different colors indeed. The reddish color that we see on its surface is due to the rusting of the iron inside the rocks, Martian soil, and the dust. Interestingly, the surface of Mars covers almost the same area as the surface of Earth, though it is half the size of Earth, thanks to its volcanoes, dynamic atmosphere, and crustal movements that have lasted for thousands of years.
Another interesting fact about the geography of Mars is that it has the largest volcano in the solar system, and its name is Olympus Mons. It is almost three times taller than Mount Everest on Earth. On the other hand, there is a large canyon system called Valles Marineris. The total length of this system (4,800 kilometers) is as long as the distance between California and New York, and this canyon is estimated to be ten times bigger than the Grand Canyon in the USA when its depth (7 kilometers) and width (320 kilometers) are taken into consideration.
4. Water
Valles Marineris is one of the hugest proofs of the fact that Mars was a wetter planet than it is today. There is still water on Mars today; however, the water cannot remain on the surface for long periods due to huge temperature differences throughout the day and the thin atmosphere. Water can only be found in the form of ice in the polar regions.
5. Moons
Similar to the Moon of Earth, Mars also has two small potato-shaped moons, and their names are Phobos and Deimos.
6. Potential for Life
As opposed to what most science fiction movies promise, life on Mars seems impossible right now. However, all the geographical findings to date strongly suggest that Mars could have been a habitable planet thousands of years ago. Maybe the saying “Men Are from Mars, Women Are from Venus” could be right. Who knows? 🙂
I hope to meet you in my upcoming posts. Take care 😀
