How and why do humans study Mars?

Answer 1

It is the next planet further out from the sun after earth. Detail from of its surface can be viewed from earth. It is the most similar to earth in various ways than other planets in the solar system (note the word similar).

Answer 2

Mars most closely resembles the Earth, and Mars might have had the same atmosphere as Earth billions of years ago. Also, we are probably still a few centuries away, but humans will make attempts at colonizing other planets. What we find on Mars now will provide the building blocks for further exploration.

Answer 3

Humans study Mars in order to better understand its geology, climate, and potential for past or present life. They use robotic explorers like rovers and orbiters to collect data and images, which helps scientists analyze the planet's surface and atmosphere. Studying Mars can provide insights into the history of our own planet and the possibility of human colonization in the future.
