Isro, Nasa to jointly launch satellite to study earthquakes and their patterns

Isro, Nasa to jointly launch satellite to study earthquakes and their patterns
06 April 2016 Current Affairs: The Space agencies of India and the US will collaborate to launch a satellite that will help study earthquake and its patterns.The Nasa-Isro Synthetic Aperture Radar, or Nisar, satellite is designed to observe and take measurements of some of the planet's most complex processes, including ecosystem disturbances, ice-sheet collapse, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides.The two countries are also collaborating in a major way in the Mars Mission project.NASA Administrator Charles Frank Bolden said they are looking to launch the satellite by 2020-21, but Indian Space Research Organisation (Isro) AS Kiran Kumar said they are looking to prepone the launch.The US is providing L-Band. It will help us look at crustal deformation. We are looking for hints at earthquake detection. Heads and representatives of several space agencies have assembled in the national capital to discuss applications of remote sensing technologies for disaster mitigation and bettering global climate change monitoring.The activity involves building a payload with L- and S- bands synthetic aperture radar. It's a new technology instrument. While Nasa provides the L-Band component of the electronics plus the antenna, which is a huge one. Isro will provide the S-Band and the payload will be integrated at Nasa and then the payload comes back at Bangalore. It gets integrated on the satellite, which is being built and will be launched by Isro.The activity involves building a payload with L- and S- bands synthetic aperture radar.

It gets integrated on the satellite, which is being built and will be launched by Isro.You can measure accurately the variations in surface topography, accuracy of millimeters. So, it's not earthquake prediction that is possible and making measurements of locations where large deformation are consistent, observation of changes in surface measures which will lead to stress levels being built up at certain locations which could help in understanding the behaviour of understanding earthquake and its phenomena. The objective is to make systematic study in timely mannerHe further said that it will give primary data of surface deformation and the frequency of the measurement is very significantly different from what is available now and that is what is being looked at globally as a new input for enabling a large number of applications to be brought about.In future, we are also looking at what we could so with Nasa in our future Mars missions. We are also looking at opportunities for some of our payloads which can be carried on their (Nasa's) programmes. This is a continuous dialouge on how we can take forward our current engagements on Mars programme.
