Mars is the only planet from the Sun that is not a planet in our solar system. It is the only planet that is visible from Earth and it is one of the largest planets in the Solar System. In English, Mars is known as the Roman god of War and is also known as the planet of the Roman Empire. This makes it interesting to speculate what might be on Mars. What exactly is Mars?
Mars is actually the Roman goddess of war. Mars has several interesting features on its surface, including dunes, volcanoes, lowlands and plateaus. All of these have created the subject of study by planetary scientists studying Mars. In fact, there are some major international planetary missions currently underway that will study Mars extensively to learn what it can offer mankind in terms of scientific research.
One way to determine what is on Mars is to use the mineralogy or the study of the mineral composition of Mars. A variety of mineral deposits can be found on Mars and the composition is very similar to that of earth. These include carbonates, sulfates, sulphides, glycated, hematites and many other minerals including water. The mineralogy of Mars therefore can be used to identify what kinds of materials were present in the ancient Martian environment and whether these materials are still present today.
The search for evidence of past life on Mars is also one area that has yielded a great deal of Mars research results. Many Mars missions have been designed to find out if there is any life existing today on Mars. Some of these experiments involve studying the mineral makeup of Mars. Other types of experiments seek to answer the question of why the planet has so much water on it. Many believe that it is due to an ocean layer that is too thin to be affected by human activity or perhaps a subsurface ocean that was trapped under ice for hundreds of millions of years. There are also a variety of meteorite landings that have yielded interesting facts about the interior of Mars.
When looking at the moon and the outer solar system there is some similarity to Mars. In fact there are several close planetary cousins of Mars that also possess a very thick atmosphere, very little gravity and also have clouds. One of these is Venus. It is possible that Mars once had an ocean like the planet Venus today, but it is not very certain. It is also possible that Mars once possessed an extremely thick atmosphere similar to Earth’s, but this is not certain either.
All of these considerations lead scientists to believe that there is some truth to the popular myth that Mars is only the fourth planet from our sun. In actuality there are several possibilities for life on Mars, including microbial life, which is believed to be the prevalent life form on Earth today. If there are microbes on Mars, it is possible that they could be using the oceans of Mars as a source of water. For this reason the Martian environment is a suitable one for microbial life to exist, and it is very likely that if there were ever living organisms on Mars that they would have left evidence for us to discover.
