Q87) NISAR mission was in news recently. What is NISAR about?
The correct option is D None of the above
Ans.87)(d)Expl. NASA-ISRO Synthetic Aperture Radar (NISAR) mission was in news recently as its first Joint Steering Group (JSG) meeting was held.
NISAR is a dedicated US and Indian InSAR mission, in partnership with ISRO, optimized for studying hazards and global environmental change.
As part of it NISAR satellite, which will be the first radar imaging satellite to use dual frequency, is expected to be launched during the year 2021. The satellite will also be
used for remote sensing to observe and understand natural processes of the Earth.
The aim and objectives of NISAR mission are:
- Design, Develop and launch a Dual frequency (L Band (24-centimeter wavelength Polarimetric Synthetic Aperture Radar) and S Band (12-centimeter wavelength Polarimetric Synthetic Aperture) Radar Imaging Satellite.
- Explore newer application areas using L and S band microwave data, especially in natural resources mapping & monitoring; estimating agricultural biomass over full duration of crop cycle; assessing soil moisture; monitoring of floods and oil slicks; coastal erosion, coastline changes and variation of winds in coastal waters; assessment of mangroves; surface deformation studies due to seismic activities etc.
In this joint mission, JPL/NASA will be responsible for design & development of L-band SAR, 12m unfurlable antenna, GPS system and data recorder.
On the other hand, ISRO will be responsible for design & development of S-band SAR, Spacecraft Bus, data transmission system, Spacecraft integration & testing, launch using GSLV and on-orbit operations.
