Mars Terrain: The Use of GIS in Measuring the Terrain of Mars

Abhijeet Modi/ November 18, 2021/ Blog

Maps are an important part of our everyday life on earth. But, what about other planets? How do the astronauts know the size of each planet and how they can explore these areas effectively? The researchers and astronauts have launched many projects to determine life on other plants and whether it is possible to survive on other planets.

The Mars Rover has already landed on the planet and it is used to get a better view of mars. Thanks to the GIS (Geographic Information System). It has now become possible for people to explore Mars, know how life would be on this planet, and get a clear picture of the total area. GIS and remote censoring have made geospatial calculations possible for people.

If you have already researched the mars terrain, you already know that a vast majority of the land is covered by red dust while the surface of the planet is rocky and filled with dry lake beds. The wind and cloud formations on this planet are quite similar to those on Earth. In fact, the large volcanoes and tornadoes on Mars can be easily observed from Earth.

The Role of Mars Global Surveyor in Mars Mission

The Mars Orbiter Laser Altimeter is used to track the surface of the planet. You must remember the Mars Global Surveyor, the aircraft which was released on the planet Mars to conduct in-depth research of the planet and its surface, including the atmosphere on the planet and the wind. It happens to be one of the only aircraft to have lasted for such a long period on the planet, collecting information about Mars, its surface, the atmosphere, and other aspects.

The spacecraft provided the researchers and astronauts with the high-resolution images of the planet. These pictures suggested that liquid water might have been on or around the Mars planet lately and it might still be present in certain portions of the planet. It is the perfect example of the GIS application in space.

The Spacecraft Launched in Mars

The tool weighed more than a ton and it featured broad cameras that captured clear and high-resolution images of the planet and its surroundings. Not only did it give details of the planet, but it also showed the structure of the asteroids around Mars. The tools on the spacecraft presented a detailed view of the magnetic properties of Mars, along with its accurate shape.

Within the first three years of launch, Global Mars Surveyor provided more information to the public about Mars than all the previous space missions combined. The spacecraft sent high-resolution photos of the planet from different angles, which was the reason why astronauts were able to figure out that liquid water might have existed around the planet. Not only that, but these images also suggested a lot about the interiors of Mars. It gave astronauts real-time data of the fluctuating weather on the planet.
