Mark Watney, a NASA astronaut must survive on Mars alone. An exploration accident left him ‘stranded’ on Mars alone with a limited food supply.
While trying to contact NASA’s office on Earth, he tried to ‘make’ food on Mars. Watney farms to make ‘water’ on Mars. However, Mars life is a novel story which was later poured into the film The Martian. The film, played by Matt Damon had enlivened the cinema screen in 2015 ago.
At that time, maybe not a few people imagined life on Mars. Unfortunately, what is told in movies is not as easy as reality.
How do you live on Mars and can humans really build lives on planets other than earth?
These two big questions are still a mystery that humans are trying to solve, including the United States Space Agency (NASA). Two days ago, the NASA mission named Insight had just landed on Planet Mars.
Unlike the previous missions, this unmanned ship will explore the core of Mars until the Mars earthquake. Later, there will not only be earthquakes or earthquakes, but there will be marsquakes or Mars earthquakes.
Furthermore, the purpose of this mission is to understand the evolution of Mars that is different from the Earth until the formation of a planet. Mars used to be known as a wet planet. However, the planet evolved into a dry and uninhabited planet.
From this gathering of facts, it is hoped that in the future there will be a human mission to Mars. In the official NASA website, it was written that the researchers were doing terraforming.
Terraforming is all the process of creating an Earth-like environment or habitable on other planets. Scientists propose terraforming to enable long-term colonization of Mars.
These scientists have an analysis of releasing carbon dioxide on the surface of Mars – like oxygen on the surface of the Earth – to thicken the atmosphere and become a blanket that warms the planet.
Unfortunately, this was immediately broken by NASA’s analysis which found that Mars did not store enough carbon dioxide that could be added to warm the atmosphere. Turning the unfriendly Martian environment into a place that astronauts can explore without life support is still impossible with the technology that exists today.
As an illustration, the atmosphere of Mars consists mostly of carbon dioxide. The component is too thin and cold to support liquid water, the most important material for life. On Mars, atmospheric pressure is less than one percent of Earth’s atmospheric pressure. Any liquid water on the surface of Mars will quickly evaporate or freeze.
University of Colorado researcher Bruce Jakosky sees not enough CO2 left on Mars to be put back into the atmosphere. “In addition, most of the CO2 gas is inaccessible and cannot be easily mobilized. As a result, terraforming Mars is not possible to use existing technology, “Jakosky said on NASA’s official website in July.
Atmospheric pressure on Mars is about 0.6 percent of Earth. With Mars far from the Sun, researchers estimate that CO2 pressure similar to Earth’s total atmospheric pressure is needed to raise enough temperatures to allow stable liquid water.
“The most accessible source is CO2 in polar ice. “It can be evaporated by spreading dust on it to absorb more solar radiation or by using explosives,” Jakosky explained.
Although the surface of Mars is not friendly to the life forms that are known today, there are some interesting discoveries from previous missions. One of them is the appearance that resembles a dry riverbed and mineral deposits which only form in liquid water material provide evidence.

In the past, the climate of Mars supported liquid water on the surface. But solar radiation and solar wind can remove water vapor and CO2 from the Martian atmosphere. The Mars Express MAVEN mission and the European Space Mission show that much of the ancient atmosphere of potentially inhabited Mars has been lost to space, swept away by solar wind and radiation.
“Of course, once this happens, water and CO2 are gone forever. Even if these losses are somehow prevented, allowing the atmosphere to build slowly by geological activity, it will take about 10 million years just to double the current Martian atmosphere, “according to a team of scientists terraforming on the NASA website.
Mars Research in Indonesia
Meanwhile, in Indonesia alone there is no specific research that leads to Mars. Chairperson of the National Aeronautics and Space Agency (LAPAN) Thomas Djamaluddin said that currently there is no specific about Mars research, especially about human shipments to Mars in 2030.
“I don’t know the certainty in 2030 even though NASA is still conducting studies on the human long-term mission to Mars which is quite extreme and far from the Moon,” he said on Tuesday.
However, Thomas revealed there are some things that need to be listened to if you want to live on Mars. “To be able to live on Mars, two main things must be prepared in a long-term mission to Mars and it is not possible to bring a lot of supplies,” he added.
First, the need for vehicles and occupancy that can protect from extreme conditions, including from energetic particles from the sun. Second, the mechanism of recycling oxygen and water and food production both during travel and living on Mars. For the record, a trip to Mars takes around 6 months to 8 months.
In the end, the limited technology and results of research while Mars still hasn’t found a bright spot in life on Mars. However, in the future when technology and research are increasingly sophisticated, maybe a fragment of The Martian film can become a reality.
