Humans have a great ambition to explore and establish colonies beyond Earth has made scientists discover solutions to start life in the environments of other worlds. One of the most important of this research has been about space farming, in which they will be researching the ability to cultivate crops in space and on other planets like Mars. To stay on Mars or for a longer space mission, growing foods and plants on-site will be essential.

In this blog, I will take you through the concept of space farming, and the agricultural technology advancements in other worlds, in addition to this, I will also cover whether crops like cardamom can be grown in the soil of Mars.

Importance of Space Farming

A long-term space mission, like a mission to Mars, needs astronauts to stay there in space for longer periods varying from certain months to years. Astronauts need to carry food with them on such missions and this becomes inefficient as well as costly. Farming in Space gives a lot of benefits:

1. Self-Renewability: Growing food in space will reduce the dependency on resupply for missions from Earth.
2. Benefits Nutritionally: The space meals that undergo processing lack essential nutrients in it. Which is necessary for good health and is contained in freshly grown foods.
3. Comforting Psychologically: Having greenery around and the act of farming will help astronauts battle loneliness and stress.
4. Production of Oxygen: As we all know plants majorly convert carbon dioxide to oxygen which makes the encircled domain more livable. 

With these many benefits, popular space agencies like NASA, and ESA and some private organizations like SpaceX are investing a lot in research and development to grow crops beyond Earth. 

Challenges Faced in Space Farming

Growing crops in space or on Mars is important despite the unique challenges that must be overcome.

1. Space Station’s Microgravity: On the International Space Station Plants experience microgravity which of course affects the growth of the crops but on Earth crops grow down to earth due to gravity then plants must rely on light and air movement for orientation.

2. Harsh Environment of Mars: Even though Mars has 38% of Earth’s gravity other factors make it difficult to grow crops on Mars making it entirely challenging.
   1.  Lower Temperature
   2. The thin Atmosphere of Mars makes it difficult to grow crop
   3. The absence of strong magnetic censors exposes the surface to high levels of radiation
   4. Mar’s soil has high levels of toxins which can damage crops.
   5. Solution: Scientists are designing controls to manage the growth of crops in the mars with AI technology.

3. Space Farming Methods: Scientists are experimenting with different agriculture to grow crops the space or on Mars.
   1. Hydroponics: This is the technique where plants grow without soil but with a nutrient-rich water solution. This method is already tested by growing the lettuce, mustard greens and radishes.
   2. Aeroponics: Nutrient rich sprayed onto their roots as the plants are suspended in the air. This helps in saving water and is highly efficient.
   3. Biogenerative Life Support Systems(BLSS): The plants absorb Carbon dioxide and provide oxygen to humans through respiration while human waste is recycled into fertilizers.

Possibilities of Growth of Cardamom in Mars

1. Analyzing the Requirements of Cardamom Growth: Cardamom also called as ‘Queen of Spice’ known for its fragment seeds. It thrives in warm and humid conditions.
   1. Temperature: 18 – 35 degrees Celsius.
   2. Humidity: 75-85 degrees Celcius. 
   3. Soil: Well-dried soil and a rich nutrient organic base.
   4. Shade: Tree cover required partially.
   5. Watering: Frequent water but not water logging with average moisture.

2. Overcoming Mar’s Environmental Challenges: Since Mars lacks moisture and a warm climate with rich organic soil, Scientists are planning to replicate the earth-like conditions inside the Greenhouse.
   1. Control of Temperature: 18-35 degrees Celcius to maintain the greenhouse with artificial heating.
   2. Regulation of Humidity: To keep the air moist to release the controlled water vapour.
   3. Substitution of soil: Hydroponic or aeroponic farming instead of toxins.
   4. Artificial Lightning: As we know mars receives only 50% of its sunlight of earth requiring the photosynthesis of lighting.

Adaptation of Generic Modification

1. This Generic Modification is another approach to the growth of cardamom on Mars
2. Development of cold-resistant and low-pressure with tolerant variants.
3. Prepare the plants in a way that uses less water and also tolerates Mars soil. 
4. Boost up the resistance to UV radiation in plants, so that they can endure the surface of Mars

These specifications are possible, but cardamom is not suitable for space farming at this stage as it needs high humidity and also grows slowly. It is appropriate to start focusing on less maintenance and fast-growing plants like potatoes, wheat, lettuce and algae which contain a lot of health and growth benefits for early colonies in Mars.

Future of Space Farming

Research on space farming is quickly moving forward. Some of the important projects going on include:

1. NASA’s Artemis Program: This program is on sustainable development of agricultural solutions for the Moon and Mars, where Artemis-I was launched in November 2022, it was an uncrewed lunar flight test and it was a success. And the next Artemis-II will be launched on April 2026 with the 4 crew members.
2. China’s Lunar Biosphere Experiment: This was the attempt to grow plants on the moon and a cotton seed sprouted too, but due to the harsh environment a sudden drop in temperature to -62 degrees Celsius made the crop dry in a day, As it needed a temperature of 24-degree celsius.
3. Initiatives of Private Space Farming: Some private companies like SpaceX and Blue Origin are exploring the options for food production in space.

In the future, we might see an independent greenhouse on Mars, robotic farmers as well as the alterations in environment to make the planets more habitable for plant life.

Final Thoughts

Space farming is a comprehensive step in making human life possible beyond Earth. While growing plants in other worlds have a lot of challenges, there are also some promising solutions like hydroponics, aeroponics, genetic engineering and climate-controlled greenhouses. 

As for the cardamom, growing on Mars is unsuitable because of its requirements at present. But with advancements in biotechnology and controlled environment and some genetic modifications, one day we may be able to cultivate even the tropical spices in space.

Space farming has become an essential part of our journey and is no longer science fiction.
