The Color of Mars
Mars is often called the “Red Planet” because it appears reddish in color when seen from Earth. The red color is caused by the presence of rust on the planet’s surface.
The Martian Atmosphere
Mars is often called the Red Planet because it appears red when seen from Earth. The color is due to the presence of iron oxide, or rust, in the Martian soil. The Martian atmosphere is very thin, and it has been blowing away into space for billions of years. This has left the planet with very little water vapor or carbon dioxide, which are two greenhouse gases that help to keep a planet warm by trapping heat from the sun. Without these greenhouse gases, Mars is a cold desert world.
The Martian Surface
The Martian surface is covered in a layer of dust and debris that is responsible for its red hue. The dust is made up of iron oxide, which is the same compound that gives rust its red color. Over time, the dust on Mars has been blown around by the planet’s wind and Covering the ground.
The red color of Mars is also due to the high concentration of iron in the Martian soil. This iron oxidizes when it comes into contact with oxygen, water, or carbon dioxide in the atmosphere, which gives it a reddish tint.
Mars gets its red color from the high concentration of iron in its soil. When this iron oxidizes, it turns red. The process is similar to what happens when iron rusts on Earth.
The History of Mars
Mars is the fourth planet from the sun and is often referred to as the “Red Planet.” The surface of Mars is covered in red dust and rocks. The red color of Mars is due to the iron oxide that is present on the planet’s surface. Mars is home to the largest volcano in the solar system, Olympus Mons. Olympus Mons is about 22 kilometers high and 600 kilometers wide.
The Ancient Greeks
The Ancient Greeks were the first to name the planet Mars. They did so because of its reddish color, which they associated with the god of war. The Romans later adopted this name for their own god of war.
Mars has a diameter of 4,217 miles (6,794 kilometers), making it about half the size of Earth. It is one of the inner planets and is sometimes called the red planet because of its reddish appearance.
Mars is home to the tallest mountain in the solar system, Olympus Mons. This extinct volcano is about 16 miles (26 kilometers) high—nearly three times higher than Mount Everest on Earth.
The Ancient Romans
The Ancient Romans were some of the first people to name the planets. They named Mars after their god of war because of its reddish color. The Romans also believed that Mars was the home of all the gods.
The Medieval Arabs
The first civilization to record their observations of Mars were the Medieval Arabs. They called the planet “al-Qahir”, which means “the conqueror”. To them, Mars represented War and Bloodshed, due to its red color. The Arabs also associated Mars with the god Ares from Greek mythology.
The Arabs were not the only ones to associate Mars with blood and war. In Roman times, the planet was named after the Roman god of war, Mars. The God Mars was said to be the father of Romulus and Remus, the founders of Rome.
The colour red has been associated with Mars since ancient times. The Egyptian deity Horus was sometimes depicted as a fierce lion with a red mane, and in Mesopotamian mythology, the planet we know as Mars was known as “Nergal”, the god of fire, war, and destruction.
The Modern View of Mars
Mars is the fourth planet from the sun and is the second smallest in the solar system. In English, Mars carries the name of the Roman god of war and is often referred to as the “Red Planet” because of its reddish appearance.
The 19th Century
In the 19th century, Mars was widely believed to be a planet very similar to Earth, with a temperate climate and intelligent life forms. This view was based largely on the work of Italian astronomer Giovanni Schiaparelli, who in 1877 made detailed observations of Mars through a telescope and noted features that he called “canali”, or channels. These observations were widely misinterpreted by the public as evidence of Martian canals built by intelligent beings in an attempt to irrigate the planet’s dry surface.
This view of Mars persisted for many years, even as more detailed observations revealed that the so-called “canals” were actually an optical illusion. It was not until the late 19th century that scientists began to seriously consider the possibility that Mars might be a barren, uninhabited world.
The 20th Century
In the early 20th century, Mars was the subject of intense scrutiny by astronomers around the world. In 1915, American astronomer Percival Lowell published a book called “Mars”, in which he put forward the theory that Mars was home to a race of intelligent beings who had built a system of canals to transport water from the Martian polar caps to the planet’s arid equator. This idea captured the public imagination and sparked a wave of Mars-mania, with people eagerly awaiting news of any sightings or messages from the Red Planet.
However, as telescopes and observational techniques improved, it became clear that there were no canals on Mars and that Lowell’s theories were unfounded. In spite of this, the idea of intelligent life on Mars persisted in popular culture, fuelled in part by stories like H.G. Wells’ ” War of the Worlds” (1898), in which Martians invade Earth. In 1938, Orson Welles caused mass panic with his radio adaptation of “The War of the Worlds”, which many listeners thought was a real news broadcast about an ongoing alien invasion.
It wasn’t until 1962, when NASA’s Mariner 4 spacecraft made the first close flyby of Mars and sent back images of a dry, cratered surface, that humankind’s view of Mars began to change. Subsequent missions revealed an even more uninviting world: a frozen desert world with a thin atmosphere composed mostly of carbon dioxide. There was no evidence of canals or intelligent life, but there were signs that water might have flowed on the Martian surface in ancient times. Today, Mars is recognized as an inhospitable world that is very different from Earth – but one that still holds many secrets about our Solar System’s history.
The 21st Century
Whereas the ancients saw Mars as a god of war, the modern view of Mars is one of a barren, inhospitable world. This change in perspective is largely due to the advent of space exploration and the close up images of Mars that we now have.

The Mariner and Viking missions in the 1960s and 1970s revealed a dry, dusty world with no evidence of life. The surface temperatures are cold, averaging about -60 degrees C (-76 degrees F), and can drop as low as -153 degrees C (-243 degrees F) at the poles. There is very little water vapor in the atmosphere and what water exists is frozen in the form of ice.
The lack of liquid water, along with the clouds of dust that often obscure the surface, make it difficult for us to imagine life on Mars. However, there is evidence that liquid water may have existed on Mars in the past and some scientists believe that microbial life could still exist underground. The search for life on Mars continues and we hope that future missions will help us to answer this intriguing question.
