Question

How can we make Mars self-sustaining and grow vegetation on Martian soil?
What all challenges will we have to face to accomplish this?

Answer 1

HERE'S YOUR ANSWER -

Under Martian gravity, the soil can hold more water than on Earth, and water and nutrients within the soil would drain away more slowly. Some conditions would make it difficult for plants to grow on Mars. This is because Mars is about 50 million miles farther away from the sun.

Difficulties and hazards include radiation exposure during a trip to Mars and on its surface, toxic soil, low gravity, the isolation that accompanies Mars' distance from Earth, a lack of water, and cold temperatures.
