- Of all the planets, Mars' climate is most like Earth. Our other neighbor, Venus, is hotter than humans could ever endure.
- Still, Mars is not exactly like Earth. The air on Mars is as thin as the atmosphere 55,000 feet above Earth, and it's almost entirely carbon dioxide. (That's what we exhale. We inhale oxygen.)
- Mars has seasons like Earth. However, the average temperature on Mars is about -80°F (-62°C). Humans will have to build and live in climate-controlled, synthetic bubbles if they are going to survive on Mars!
- Mars has frozen water today.
- Mars used to have a thicker atmosphere. So for water to flow like it did once in the past, the Red Planet would need a thicker atmosphere again. Something must have changed in the past few billion years. What changed? It is thought that the Sun’s energy striking the atmosphere must have “stripped” the lighter forms of hydrogen from the top, scattering the molecules into space. Over long periods of time, this would lessen the amount of atmosphere near Mars.
- Mars is often called the "Red Planet"
- Mars is the fourth planet from the Sun.
- Mass: 641,693,000,000,000 billion kg (0.107 x Earth)
- Known Moons: 2
- Orbit Period: 686.98 Earth days (1.88 Earth years)
What would we do if we would Live on Mars
It is a very common belief that one day humans will not be able to sustain life here on earth.. Would our daily activities no longer be something we can do or would it not be too much different from the way we live on earth? If humans were to live on Mars one of the biggest differences would be the amount of time in a day and the amount of days in a year. Days would be about an half hour longer on Mars than on Earth and years would be 687 versus 365 days. Another big difference would be the temperature we would be experiencing. Since Mars is located further from the sun than Earth, it would be a lot colder there. The temperature on Mars is about -63 degrees which is about 120 degrees colder than here on Earth! Since the sun is so much further away it will look a lot smaller to us. Although it is further away and much colder there, you still would get extremely sun-burnt while on Mars! This is because Mars lacks the protective ozone layer we have in Earth's atmosphere. We would have to come up with some seriously strong sunscreen to not get sun-burnt! Mars atmosphere is mostly carbon dioxide, so humans would have to walk around with oxygen tanks in order to survive. Since the atmosphere is mostly carbon dioxide and it is extremely cold there, you would see white flakes that look like snow falling down. These white flakes are actually crystals of frozen carbon dioxide which is also known as dry ice. On Mars we would still experience winter and summer seasons thanks to the planets tilted axis. On Mars one would be expected to see some pretty outstanding sights such as vast canyons, giant mountains and sand dunes. The air on Mars has a per-meant veil of dust, giving the day time sky an orange tint although the sunrise and sunset would be blue. Ice clouds similar to the cirrus clouds we see on Earth complete this landscape. Mars is more like a desert world because its atmosphere is very thin (only 1% as massive as our own), temperatures are distinctly chilly and there is no liquid water. Scientists are estimating that the first humans will land on Mars in about 30 years. They also think that they will have to commit to being up there for a couple years to make the several months long trip worth it. The first priorities for long term visitors staying on Mars would be to set up some type of shelter. This shelter would possibly have to be underground at first. They would also have to set up some type of power source. They would need to set up solar panels or a nuclear power plant. By doing this, it would allow explorers to separate oxygen out of the Martian atmosphere's carbon dioxide and extract water from hydrated minerals in the soil.
