Is Mars Hot or cold?

Most likely to be the next big space story, the long awaited discovery of whether or not Mars is truly cold or warm has many scientists weighing in. Many theories have been formulated as to why Mars may not be cold. In order to determine the planet’s atmosphere, or “osphere,” scientists use a variety of methods, including Can-Sat instruments that are able to take a short image of the surface, and other equipment that do much more. For instance, the European Space Agency uses Can-Sat to take long-term pictures of Mars’ surface.

Since the planet is so cold, it would make sense that there would be absolutely no water on the surface. However, there are indications that water flows over the surface at different temperatures, which scientists think is caused by liquid water volcanoes, which appear all around the planet. These volcanoes form from lava that erupts on the planet’s surface. The cooled lava then hardens into rock and can form mountains hundreds of meters high. If there was water present in the past, there may be sulfuric rocks buried beneath the surface which contain organic molecules that were heated up when the volcano erupted.

Is Mars Hot or cold? Another question that scientists ponder is the existence of an atmosphere, or “osphere”, around the red planet. One proposal is that the planet obtains nearly two times as much solar radiation as Earth, which means it receives much more heat than Earth. Since Mars is thought to have once been very hot and very cold, its Atmosphere could be very thin and can easily become a cloud of vaporized gases like those that are present at times of Earth’s global thermostat malfunction.

Scientists think that the planet has a “biotic” environment in which water can exist in liquid forms, and that this environment is similar to what was found on Earth. Perhaps microbial life forms exist in liquid water pools hidden below the surface of Mars. Some studies have shown that certain types of bacteria can exist in the liquid water, and that these might have the ability to create life. Is Mars really cold or hot?

How do you find out if Mars is “warm” or “cold?” By taking accurate measurements of the planet’s temperature. If you have ever looked up at a surface on another planet, you might have noticed that the surface temperature appears to be near the freezing point of water. We call this “snow.” The same thing happens on Mars. If you take a piece of frost from Mars and place it on Earth, you will find that its temperature is very close to that of the surface of Mars, which means that there is little or no difference in temperature.
