New Delhi
ISRO and NASA together are launching such a satellite which will keep an eye on the whole earth. The name of this mission is NISAR (NASA-INRO synthetic aperture radar).
It on 30 July 5:40 pm The Satish Dhawan at Sriharikota in Andhra Pradesh will be launched from the Space Center.
Both India and America have technology in Nisar. It has two special radar L-bands (of NASA) and S-band (of ISRO), which will send very clean and detailed photos of the earth together.
This satellite will help scientists to understand the changes in earthquakes, volcanoes, landslides, snowfall, forests and farming. This satellite will take pictures of the entire earth every 12 days.
What is special in this satellite:
This satellite weighing 2400 kg is made on I3K structure of ISRO
It has a large 12 meter antenna, which will open by spreading a 9 meter long boom in space.
Both radar technology can take pictures up to 240 km width together
This mission will work for 5 years and its data will be free and open for all
What information will be given?
It will be launched in the Earth’s orbit, which will analyze the entire earth and glacier every 12 days. The data received from this will find out how important is in carbon regulations in forest and wetland. Actually, forest and wetland are very important to deal with climate change. Due to these, there is a regulation of greenhouse gases in the environment.
Along with this, this satellite will give information about tornado, storm, volcano, earthquake, melting of glaciers, hurricanes, wild fire, increase in water levels of seas, farming, wet earth, reduction of snow etc.
With this satellite, information will also be available about the garbage accumulating around the earth and the dangers coming from the space towards the earth. Information about lack of light and increase in it will also be available from Nisar.
Mission will be completed in four phases
Launch phase – To make satellite into space
Deployment phase – Spreading antenna and turning on the system
Commissioning Phase – Investigation and setting in the first 90 days
Science phase – Start taking fully data related to science
Will keep a close watch on India’s borders
Pictures of high-regulation from this satellite will help the governments of India and the US under the supervision of glaciers in the Himalayas. It can also help the government in keeping a close watch on the borders of India with China and Pakistan.
Why is it important for India?
Its purpose is to achieve better planning, agriculture and weather related space inputs. Nisar has a synthetic aperture radar, which will send an image of excessive high resolution compared to photographs from any other satellites in the country. It has the ability to see the back of the clouds and also in the dark. This will be one of the most expensive meaning imaging satellites.
