NISAR mission

Subject: Science and Technology

Context:

Thursday’s failure, however, is a big cause of worry for the NISAR mission

NISAR stands for NASA ISRO Synthetic Aperture Radar Mission
It aims to study the hazards and global environmental changes and slated to launched in 2020-21.
NISAR is a dual frequency (L & S Band) Radar Imaging Satellite. It will be the first radar imaging satellite to use dual frequency.
Will be launched in a Sun Synchronous Low -Earth
It is designed to observe and take measurements of some of the planet’s most complex processes, including ecosystem disturbances, ice-sheet collapse, sea level rise, and groundwater and natural hazards such as earth quakes, tsunamis, volcanoes and land slides and will support a host of other applications
NISAR will observe Earth’s land and ice-covered surfaces globally with 12-day regularity on ascending and descending passes, sampling Earth on average every 6 days for a baseline 3-year mission.
The satellite is likely to be launched from India aboard an Indian launch vehicle.
