Creating maps has been a fundamental advancement in modern exploration, and the production of height data in map production has bettered our understanding of earth’s terrain. By mapping the contours of the planet we are able to see the extent of the depths of the ocean and the reach of the highest mountainous peaks. While the technology behind collecting height data is most commonly used in surveying, it has become a fundamental factor in understanding new geological features in remote areas, including other planets.
The computer software used for collecting height data uses a set of parameters that are represented by bold colours and exaggerated textures. This method makes it easier to determine physical features such as waterways, forested areas, and even soil types. There are many applications for such information such as tracking areas of deforestation by loggers and even keeping an eye on tectonic movement.
Recently there has been major movement in the East African region where the horn of Africa is beginning to move away from the rest of the continent. Through using equipment that measures height data through taking thousands of pictures simultaneously, it is possible for geologists to determine the rate and extent of the separation. Trying to take measurements using traditional cartographic methods are impossible for the fissure as there are dangerous gasses that would be fatal if respiration equipment failed.
The same technology can be applied to areas so remote that that we are not even able to reach them. This includes the depths of the deepest oceans where tectonic movement is a common feature in a rapidly changing environment and the surface of planets such as Mars. It is widely recognised that we now know more about outer space than we do about the oceans of our own planet. Thankfully, height mapping has enabled geologists to understand more than ever about our oceans and the way the planet has changed over millennia.
Nevertheless, the desire to know more about worlds other than ours continues to fuel space exploration, in particular understanding the geographical features of the red planet. Geographical wonders such as Hellas Planitia have been mapped using height data, the results of which reveal an impact crater that is 7km deep, and 7,000 km across, the largest visible feature of its kind in the solar system, even though it is believed to not be the biggest in existence. Collecting this type of data will not only help unravel the secrets of Mars, but allow us to better understand how life developed on Earth
Unlike a mission to the moon, which can be done in three or four days, a journey to Mars — some 140 million miles away — could take more than six months each way. For a trek that long, astronauts would need to set up a system of supply terminals in profound space to refuel their rocket.
Be that as it may, how? As insane as it sounds, one answer is – asteroid mining.
Asteroids, those rough sections revolving around the sun, can contain water, oxygen, valuable metals and different components that could be utilized to deliver fuel and life-emotionally supportive networks in space – all at a much lower expense than shipping them from Earth. There are a huge number of asteroids, running in size from expansive stones to scaled down planets several miles over.
Extricating these assets will be costly and massively troublesome – envision attempting to bore into a vast rock plunging through space at fast – however a few private companies accept they’re up to the errand with most recent advanced computer technology .
