Landsat 9: Know how particular NASA’s new Landsat 9 satellite is

cosmos science Technology

Ordinary people think that NASA’s campaigns are only for space exploration. It has indeed been the work of NASA to take all the satellites of America to space. But many of NASA’s campaigns are also for observation of Earth. On Monday, NASA has sent a powerful and advanced satellite into space, whose job is to monitor the Earth. The work of Landsat 9 is to help its companion satellite Landsat 8, by reaching space. Together, both satellites will take pictures for NASA.

With the help of these pictures, which will be taken by both satellites circling the Earth every eight days, the health of the Earth will be monitored. At the same time, people will be able to monitor the essential sources of the Earth, such as agriculture, irrigation, water resources, Make proper use of forests, etc. Satellites will collect pictures of the planet by making one revolution of the Earth every 99 minutes and 14 revolutions every day for these eight days. These photos will be added to the data sets that have been available to people for 50 years for free. NASA says the capabilities of medium-resolution images will help researchers identify signs of human activity and their effects on Earth.

Landsat 9 is an advanced technology advanced satellite which is the ninth satellite of its series. It will be operated by NASA’s Goddard Space Flight Center and has two instruments. The Operational Land Imager 2 (OLI-2) will take images of Earth in visible, near-infrared, and shortwave infrared light. At the same time, Thermal Infrared Sensor 2 (TIRS-2) will study the temperature of the Earth’s surface areas.

Landsat 9 is a joint mission of NASA and the US Geological Survey, helping to understand Earth’s processes and their many changes for the past five decades. The Landsat series has measured many changes such as the speed of glaciers in Antarctica, the amount of water used for agriculture, deforestation in the Amazon forests, etc. Apart from this, the status of forest fires in many countries, including Australia, America, Brazil, has also been monitored.

At present, NASA’s Landsat 7 and Landsat 8 satellites are working, and their orbit pattern is every 16 days so that every place of the Earth is taken every eight days. NASA says that Landsat’s instruments revolve around the Earth, taking pictures of 185 kilometers long at a time. Its pixel is 30 meters big, which is equivalent to a baseball field or an American farm.

NASA launched the first Landsat in 1972, named Earth Resource Technology Satellite (ERTS), which took 8 million pictures of Earth. NASA says that these satellites give scientists a global view of the changing Earth. These changes may be due to natural causes such as earthquakes or human-caused causes of greenhouse gas emissions, increasing global warming, and temperatures.

At present, the Earth is facing the dangerous side effects of climate change. To prevent further damage, all the countries of the world are scratching their heads. Observations from space may help in finding a better view of evolution. Apart from this, free information will prove helpful to many countries in better use of their agricultural resources. NASA says that satellite information has also proved beneficial to farmers in deciding better and valuable crops.
