Signs of Life on Mars

Everybody knows about Mars. It is the fourth closest planet to the sun in the solar system. It is the second smallest planet after Mercury with a diameter of 6,719 km which is about half the size of our planet, Earth. It is also known as the red planet because of its rusty color due to the presence of large amounts of iron oxide (rust of soil and rocks) that creates a plain red landscape.

Mars has been the center of attention ever since it has shown evidence of life support. Many countries have successfully completed their mission to Mars, including India. This is to study the planet in detail and to find ways to make life on Mars a reality. Let’s take a look at the conditions that make life on Mars possible.

  • The presence of water in the soil of Mars as found in earlier studies made scientists believe that Mars can harbor life
  • The climate of this planet is neither too hot nor too cold. The temperature on Mars is about 20° C which is suitable for the survival of human life.
  • Although it has a thinner atmosphere than Earth, it can protect humans from the harmful cosmic rays of the sun to a certain extent.
  • Mars has a similar day and night cycle like the Earth. A day in Mars is 24 hours 39 minutes and 35 seconds long.
  • Gravitational force of this planet is 38% of that of the Earth. Scientists think that it is sufficient for a human body to adapt to it.
  • The planet receives enough sunlight to nurture life.

Living on Mars might be difficult than living on Earth. Based on current studies, Mars does support human life but has extreme conditions that make it difficult to adapt. We may need external sourcing like high technology and support systems to survive on this planet. However, scientists are still exploring Mars in order to provide more viable solutions to make it the next human colony.
