ISRO and NASA are jointly working on the synthetic aperture radar mission to developed and launch a dual freq. satellite by 2021.
The satellite will be the world most expensive earth-imaging satellite till date.this cost is about 1.5 $ billion.
This mission is NASA's JPL(jet propulsion laboratory will be design and make its include a GPRS SAR system to record the data this is a first radar imaging system.The data obtained from NISAR mission is not meant for building climate resilience. However, the data acquired from this mission will be useful in developing certain applications,
which include -
(i) identifying crevasses in the glaciers hidden by fresh snow, where human movement takes place,
(ii) identifying the snowpack parameters as an input in Avalanche forecasts,
(iii) studying Glacial Lake Outburst Floods (GLOF) hazards, and
(iv) identifying inundated area due to floods/ cyclones. These applications could help in taking measures to minimise loss of human lives.
- The satellite will take weekly snapshots of Earth -- using the two radars -- that will provide time lapse images of the motion of tectonic plates, ice sheets and changes in vegetation over land in agriculture and forests.
- The data obtained from NISAR mission is not meant for building climate resilience.
- However, the data acquired from this mission will be useful in developing certain applications like identifying crevasses in the glaciers hidden by fresh snow, where human movement takes place, identifying the snowpack parameters as an input in Avalanche forecasts, studying Glacial Lake Outburst Floods (GLOF) hazards or identifying inundated area due to floods/cyclones.
- These applications could help in taking measures to minimise loss of human lives.
Lanched date: it is expect that to lanch in 2021 (3 year).
COST: 1.5 $ billion.
