Living on Mars: Not like a dream!
Referring to the mission to conquer Mars, billionaire Elon Musk said in an online interview published on April 18: “It is important to emphasize that life on Mars, especially during this time In the beginning, it will not be luxurious. The journey will be very dangerous, cramped, difficult and hard.”
Going easy, maybe not coming back!
The American billionaire has compared current efforts to conquer Mars to the advertising of explorer Ernest Shackleton’s 1900s Antarctic expedition. This commercial is considered a legend when it calls for healthy men to make the dangerous journey and the way back is “not guaranteed”.
The SpaceX CEO said: “The invitation from Mars is so dangerous, there are so many risks that we may not be able to return. It is a difficult mission.”
Living on Mars, a planet with an average temperature of -62.22 ⁰C, will be much more difficult than living in Antarctica, where the temperature is -56.67 ⁰C. This is because Mars has a hard surface, thick layers of rock and deep trenches, along with a lot of volcanoes and canyons.
The planet also has a gravity of only one-third that of Earth and a thinner atmosphere. Therefore, humans cannot breathe in this environment. According to the sheet Business Insiderhumans without special support equipment will die within minutes on the Red planet due to low atmospheric pressure.

To realize his dream of conquering Mars, billionaire Musk plans to build a standard-sized city here.
In 2019, Musk estimates it will take up to 1 million tons of cargo to build a self-sustaining city on the Red Planet. The process is expected to cost between $100 billion and $10 trillion. The world’s richest man hopes Mars settlers will have a chance to “rethink social issues”.
“Human civilization could end for external reasons like a giant meteor, a supervolcano, extreme climate change or a third world war, or you know what,” Musk said. , any reason”.
The Tesla boss also announced that SpaceX will determine a future ticket price for the journey to Mars that is relatively affordable for most people, with an assumed number of $ 100,000. In 2020, Mr. Musk shared the idea of building 1,000 Starship spacecraft within 10 years and planning to send 1 million people to Mars by 2050.
Mr. Musk said at the time that the first man could land on Mars in 2029. SpaceX would build the city in the coming decades, but Mr. Musk, 50, predicted he would be “dead long before” dream come true. “I’ll probably be dead long before this happens, but I’d like to see us make great progress on this project,” Musk said.
Shipping and food costs are expensive
It’s likely that future Mars arrivals will have to live on a vegan diet, at least initially due to the high cost of transporting and storing food.
Scientist John K. Strickland from the US National Space Association has studied this issue and commented that if the diet of fish is maintained, the number of people living in a dome on Mars must decrease. half that of a vegan.
Mr. Strickland says a community of about 5,000 people who eat only plants can be sustained by a farm of about 900,000 square meters.2 – spread over 4 floors, materials and seeds are brought to Mars by Starship.
Mr. Strickland said that to achieve billionaire Musk’s goal, it will take about 5,000 Starship trips, each carrying 200 tons of cargo before it can produce food on Mars. These shipments could be sent ahead of human missions to Mars in the 2030s.
Once all the equipment arrives, food production can begin and Mr Strickland said the initial growing area will require about 185 square meters and 100 kilowatts of electricity per person. This means that to maintain an initial construction team of about 100 people, billionaire Musk will have to plan for 10 MW of electricity and nearly 18,500 square meters of arable space.
Since there are no fossil fuels on Mars, solving the energy problem will be difficult when installing giant solar panels where weaker sunlight will not be as efficient. on the earth.
Some of this energy could be used to assist geologists in finding mineral sites for the production of settlement building materials. That’s why, Mr. Strickland suggested that instead of doing it alone, SpaceX should take the lead and cooperate with the US National Aeronautics and Space Administration (NASA) as this will allow for pooling of resources.
According to the Daily Mail, at least until 2040, basic activity will take place, including the first wave of cargo transportation and reclamation because the spacecraft can only land almost every two years due to the distance between the two. Earth and Mars. At its closest point, Mars is about 54.5 million km from Earth but at its furthest point, the Red planet is 402.3 million km from Earth.
