According to some scientists, the chances of growing a forest on Mars are slim

Here are some reasons why:

• Temperature Mars is about 50 million miles farther away from the sun than Earth, so it receives less sunlight and heat. The planet’s extreme cold temperatures make it difficult for life to sustain. 
• Atmosphere Mars’ atmosphere is not as thick as Earth’s, which keeps our planet warm. Mars’ atmosphere is also extremely thin and does not shield plant life from UV radiation. 
• Soil Martian soil contains toxic constituents that inhibit life, such as perchlorate salts. 
• Surface conditions The planet’s atmosphere and surface conditions would cause trees to die. Most trees would freeze before they had a chance to do anything. 

However, some researchers believe that growing plants on Mars is feasible. For example, researchers at Wageningen University in the Netherlands have been growing plants in soil that has the same composition as soil found on Mars and on the Moon. 

The the temperatures over the planet as a whole are too cold for trees to reproduce or grow. They could survive at those temperatures for a while but nothing more. Only in a few low-lying valleys close to the equator in summer does the temperature ever get warm enough for them to grow and reproduce

Is it possible to farm on mars

While it’s not possible to farm on Mars with Earth plants, some say it’s possible to grow crops using alfalfa-treated Martian soil. For example, research has shown that turnips, radishes, and lettuce can grow in simulated Martian soil treated with alfalfa

Researchers are growing crops in labs using fake Martian soil to prepare for the possibility of astronauts growing their own food on Mars. To grow plants in Mars soil, you need to add nutrients and remove toxic chemicals. Earth soil contains microbes and other organic matter that help plants grow, but Martian soil is mostly crushed rock. Martian soil also contains perchlorates, a type of chemical hazardous to the human body. 

A sustainable food system on Mars would involve:

• Greenhouse technologies Advanced greenhouse technologies, like vertical agriculture, can create a suitable controlled environment for crops. 
• Protein Protein could be produced through cellular agriculture and precision fermentation. 

With an atmosphere 100 times thinner than Earth’s, only half the amount of sunlight, no known accessible fresh water, and average temperatures of -81 degrees Fahrenheit, Mars is the most challenging environment in which humans have ever planned to produce food

Food pods and vertical farming could help us grow crops on Mars

Even before we reached the moon, humans had been making plans to send people to Mars, and in recent years, the dream has looked closer to becoming reality. NASA plans to have boots on the red planet in the 2030s, while Elon Musk’s SpaceX plans to get there even sooner.

The difficulty isn’t solely getting astronauts to Mars but also sustaining them once they’re there; you can’t simply grow potatoes in its soil – despite what Matt Damon would have you believe in the movie “The Martian.”

A startup called Interstellar Lab believes it may have the solution. The Paris and Los Angeles-based company has designed a controlled-environment capsule system that could one day allow crops to be grown in space.

A multi-planet species”

“Interstellar Lab is the pursuit of a child’s dream in the context of the climate crisis on Earth,” says CEO Barbara Belvisi. “At the youngest age, I dreamt of becoming a multi-planet species and to live under domes on other planets, surrounded by plants.”

Belvisi spent a year with engineers at NASA AMES Space Portal before launching Interstellar Lab in 2018. Its Nutritional Closed-Loop Eco-Unit System, or “NUCLEUS,” is a modular structure composed of nine cube capsules designed to provide a nutritious diet for four astronauts for the duration of a two-year mission. Belvisi says it is capable of producing fresh microgreens, vegetables, mushrooms, and even edible insects.

“The initial focus was to build a regenerative food production system to advance sustainable farming on Earth,” says Belvisi. “But I asked, ‘what if the technology we will need to live in space could help us live more sustainably on Earth?’ That’s how the concept of advanced controlled-environment modules for Earth and space was born.”

Agriculture in harsh environments

Inside the NUCLEUS capsule cubes, plants are grown in vertical crop systems, the method many scientists consider to be the best option for Martian agriculture. 

Vertical farming is a method of growing crops without soil in a controlled environment, delivering nutrient-rich water straight to a plant’s roots. It can use significantly less water and fertilizer than traditional outdoor agriculture, and by continuously recirculating water, it creates very little waste

How many years can we live on Mars?

‘Our simulations show that an increase in shielding creates an increase in secondary radiation produced by the most energetic GCR, which results in a higher dose, introducing a limit to a mission duration. ‘We estimate that a potential mission to Mars should not exceed approximately four years

Can you live on Mars in 2050?

Robotic mining that can provide water and fuel is the key to developing a colony on the red planet within the next 30 years. Mars will be colonised by humans by the year 2050, as long as autonomous mining processes quickly become more commercially viable

Is there any oxygen on Mars?

Oxygen is Rare on Mars

There is less than 1% of air on Mars as there is on Earth, and carbon dioxide makes up about 96% of it on Mars. Oxygen is only 0.13%, compared to 21% in Earth’s atmosphere

Can trees grow on Mars?

The plants would probably be housed in a greenhouse on a Martian base, because no known forms of life can survive direct exposure to the Martian surface, with its extremely cold, thin air and sterilizing radiation. Even then, conditions in a Martian greenhouse would be beyond what ordinary plants could stand.

NASA – Designer Plants on Mars

Take the cold tolerance of bacteria that thrive in arctic ice, add the ultraviolet resistance of tomato plants growing high in the Andes mountains, and combine with an ordinary plant. What do you get? A tough plant “pioneer” that can grow in Martian soil. Like customizing a car, NASA-funded scientists are designing plants that can survive the harsh conditions on Mars. These plants could provide oxygen, fresh food, and even medicine to astronauts while living off their waste. They would also improve morale as a lush, green connection to Earth in a barren and alien world

Redesigning Life for Mars”. Credit: North Carolina State University The research is being sponsored by the NASA Institute for Advanced Concepts (NIAC), which investigates revolutionary ideas that could greatly advance NASA’s missions in the future. The proposals push the limits of known science and technology, and thus are not expected to be realized for at least decade or more.  The plants would probably be housed in a greenhouse on a Martian base, because no known forms of life can survive direct exposure to the Martian surface, with its extremely cold, thin air and sterilizing radiation. Even then, conditions in a Martian greenhouse would be beyond what ordinary plants could stand. During the day, the plants would have to endure high levels of solar ultraviolet radiation, because the thin Martian atmosphere has no ozone to block it like the Earth’s atmosphere does. At night, temperatures would drop well below freezing. Also, the Martian soil is poor in the mineral nutrients necessary for plants to thrive. “Our idea is to enable plants to survive on Mars by adding features from microscopic organisms called extremophiles that live in the most inhospitable environments on Earth,” said Dr. Wendy Boss of North Carolina State University. Boss and her colleague, Dr. Amy Grunden, also of North Carolina State, head the research team working on this project. The team uses the techniques of gene splicing to remove useful genes from extremophiles and add them to plants. (A gene is a molecular instruction that specifies a feature for an organism, such as eye color, height, the ability to digest certain foods or resist toxins, etc.)

According to NASA, plants would likely be kept in a greenhouse on a Martian base because the Martian surface is too cold and has thin air and sterilizing radiation. Even then, the conditions in a Martian greenhouse would be beyond what ordinary plants could tolerate

Some say that plants would die if exposed to the elements on Mars. Mars’ temperature can reach 200 degrees below zero. Mars also gets half as much sunlight as Earth, so the atmosphere is only filtered half the time. This means that any plant life would turn yellow, sickly, and dead within a week. 

Mars’ soil is also mostly toxic. Some Martian soil is high in heavy metal content, which would be toxic for plants that absorb them and for any humans that would then ingest those tainted plants. 

However, some say that low-maintenance plants like lettuce, onions, kale, peas, and garlic could potentially grow on Martian soil

Can we increase oxygen in mars by growing forests

However, NASA has funded scientists to design plants that can survive on Mars, including some that could produce oxygen. The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) instrument on NASA’s Perseverance rover has produced oxygen on seven experimental runs. MOXIE provides oxygen equivalent to a tree in all seasons. 

Scientists have also conducted plant experiments using volcanic soil from Hawaii, which is similar to Martian soil, and found that plants can grow in these soils. 

Could we plant trees on Mars to take in CO2 and give out oxygen?

Not immediately. The problem is that while a tree takes in CO2 during daylight hours, it also takes in O2 during all hours for respiration. That’s right, the planet builds up carbohydrates by photosynthesis and then tera=s them down as fuel for growth and transpiration. A lot of the carbs go into wood, but more are used up.

These two systems are essentially independent; the O2 give out by photosynthesis is not banked for use burning carbs; it is simply released into the atmosphere. On Mars, they would disperse and spread all over the planet; good luck in collecting enough for the tree to survive. In general, trees are overall carbon sequestrators – they cull CO2 and make wood out of it. Of course, the decay process every year at leaf fall and the final rotting of the wood potentially returns all the CO2 to the atmosphere.

You will need a substantial oxygen partial pressure before trees can be used outdoors.

There are other problems that Earth-grown trees are not equipped to handle. Perhaps a few centuries of gene splicing will fix that. Yeah, that’s right – GMOs to Mars!!!

Can we grow plants on Mars to create oxygen?

A tough plant “pioneer” that can grow in Martian soil. Like customizing a car, NASA-funded scientists are designing plants that can survive the harsh conditions on Mars. These plants could provide oxygen, fresh food, and even medicine to astronauts while living off their waste

How can we add oxygen to Mars?

A sustainable oxygen supply on the red planet can be achieved by converting carbon dioxide directly from the Martian atmosphere. A new solution to do so is on the way: plasma technology. Why plasma? Low-temperature plasmas or non-equilibrium plasmas are ionized gases where only a fraction of the gas is ionised.

LIVING ON MARS:
HOW TO PRODUCE OXYGEN AND FUEL TO GET
Sending a manned mission to Mars is one of the next major steps in space exploration. Creating a breathable environment, however, is a substantial challenge. A sustainable oxygen supply on the red planet can be achieved by converting carbon dioxide directly from the Martian atmosphere. A new solution to do so is on the way: plasma technology.
Space exploration is on the verge of an exciting new era, with Mars on the agenda. Ambitious programmes on Mars exploration, Mars Sam- ple Return (MSR) missions and the prospect of future manned missions have been recently presented by the main space agencies – ESA (European Space Agen- cy), NASA (National Aeronautics and Space Adminis- tration), Roscosmos (Roscosmos State Corporation for Space Activities, Russian Federation) and JAXA (Japan Aerospace Exploration Agency) – often in partnership with private companies.
Travelling to Mars is an extraordinary endeavour. The distance between Earth and Mars varies between 55 and 400 millions of kms, depending on the position of the planets on their orbits. The correct conjugation of trajectories implies that there is an optimal window for
launching approximately every two years, corresponding to a launch along the Hohmann transfer orbit represented in figure 1, for a trip of around six months, and that in a manned mission astronauts would have to stay on Mars for about one year. Clearly, any local resources that can be used will reduce the logistics and costs of the mission, increase self-sufficiency and reduce risks to the crew. Hence the interest devoted nowadays to in-situ resource utilisation (ISRU), the harnessing of resources in the exploration site that would have to be brought from Earth otherwise.
The main component of the Martian atmosphere is CO2, accounting for about 96% (with approximately 2% Ar and 2% N2). This is the resource of interest here. Indeed, carbon dioxide can be used as a raw material to locally produce oxy- gen, which can be collected and made available for breathing. The process relies on the decomposition of carbon dioxide

In The martian – a science fiction book by Andy Weir and a Hollywood movie blockbuster, Mark Watney is stranded on Mars after his fellow NASA astronauts think he died and left the Red Planet without him. Watney is left with space suits and a controlled-environment habitation module (or Hab), but he does not have enough food and water to survive until NASA sends a rescue mission.

Several years could go by while Watney waits to be rescued, and many things could go wrong. For example, if the system that provides him with oxygen stops working, Watney could die, because the atmosphere of Mars does not contain enough oxygen for humans to survive. The good news is that Watney, who is a botanist, has some potatoes in the Hab that he can use to produce more food as he waits for NASA to rescue him. The bad news is that Mars is a desert planet, where no plants have ever grown before.

In the story, Watney’s botany skills help him survive the ordeal. He uses the potatoes NASA packed for his Mars expedition along with his own feces and manages to grow potatoes in a small farm inside the Hab. Also, his knowledge of chemistry allows him to make water, which he uses to irrigate the potatoes.

Improvising a Martian potato farm and producing water from scratch sound more fiction than science. But research suggests that some soils on Mars could be used to grow plants.

So, how exactly did Watney fertilize Martian soil? Is it possible to make water on Mars?

Fertilizing Mars

Research suggests Martian soil has some of the nutrients plants need to grow and survive (see “Plants’ Nutrients,” right). But because of Mars’s extremely cold conditions, plants such as Watney’s potatoes would need to grow inside a controlled environment, such as his Hab. Also, just like on Earth, nutrients in Martian soil may vary from place to place. So, people stranded on Mars should be prepared to turn to ingenious ways for making the soil more suitable for plant growth—even if the only option is using their own feces, as Watney did.

The idea to grow forests on mars is a very fascinating idea 💡 and as our Artemis missions are finished and the journey to mars colonisation begins and our technology that is expanding leaps and bounds we can in future use water and grow forests on mars by making its soil fertile and choosing right plants and trees 🌲 there as our AI is growing very fast it can help us to find a solution and we can grow forests on mars and make it more habitable
