why and when and how scientists are making plant in mars?
Answers
Answer:
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?
Earth-like planet
Even though Mars has an environment that is harsh for life as we know it, it appears to be the most habitable planet in our solar system, besides Earth. According to NASA, billions of years ago, Mars even had oceans like our own. Some places on Earth have been used to study Mars, since their environments are somewhat similar to conditions on Mars. Parts of Antarctica, Hawaii, and South America are examples of such places.
Scientists have been studying Mars since the early 1960s. They have sent small spacecraft that flew by, orbited, and landed on Mars. These spacecraft found that although some places on Earth look like Mars, the Red Planet is indeed a harsh environment for life.
The atmosphere on Mars has about 95% carbon dioxide, which would make it impossible for humans to breathe. Mars is also much colder than Earth. This is mostly because the Red Planet is farther away from the sun than Earth. NASA’s Viking mission, which landed on Mars in 1976, recorded average temperatures of –81 ºF, which is colder than either the North or South poles here on Earth. If exposed to Mars’s temperatures, plants, humans, and other living beings would freeze
