A satellite moves around a specific path, which is called its orbit. The area these satellites cover depends largely on the orbit of the satellite that’s released into space. Now, since the Earth keeps rotating on its axis, a different view of the Earth is captured by the satellite every time Earth completes its round in orbit. This picture is captured from different angles, thus giving researchers a clear picture of different elements of our planet along with a view of the surrounding asteroids.
The sun-synchronous orbit is used for remote sensing or geospatial applications. In these orbits, the satellite travels from the north pole to the south pole. These are highly recommended for satellites that require a considerable amount of sunlight throughout the day. The sun-synchronous satellite helps achieve a global image of the planet, plus it captures the sun and the earth from the best angles. That’s how they help give you a clear and better view of Earth. There have been quite a few tools launched to improve the GIS’s data collection and analysis ability.
Satellites Orbiting around Earth, Mars, and other planets
You must have heard of the ESA’s successful mission that involved Rosetta, which was supposed to cover a massive distance (almost five times the distance between earth and sun). It completed the journey in 10 years and arrived at comet 67p successfully. The GIS had a major role in launching Rosetta and having it launched into space.
Similarly, there are plenty of satellites in space orbiting Earth, Mars, and other planets and collecting valuable information about different planets and their impact on our life on Earth. It is only possible to imagine how far they are located from the Earth, but how closely they can be analyzed and evaluated using remote sensing tools. These satellites orbit the planet Earth and collect pictures of the surroundings on an everyday basis to give scientists a better understanding of how the planets work and temperature.
The Mars Project
The recent Mars surveyor project concluded that water did exist on Mars billions of years ago. Today, some portion of that water exists, but it is in the frozen form, unlike the water streams that flowed at great streams in the past. Some traces of the fact that water existed on Mars can still be seen through these satellites that rotate around the Mars orbit. The water, however, has turned into the frozen and solid form where the vapors are seen in the atmosphere of the planet. The frozen ice caps are never expected to melt since they have a below freezing temperature and the little fluctuations on Mars will make no difference to their state.
Remote sensing has made it possible for the world to get a closer look at the planet from different angles. The high-resolution images show us a lot of information about these planets and whether life existed on these planets. The satellites keep orbiting on their paths every day, collecting pictures of the Earth and surrounding areas.
