NASA, ISRO prepare to Launch Joint Space Mission

 

 

Context: The NASA-ISRO Synthetic Aperture Radar (NISAR) is set to be launched in the first quarter of 2024 after a few tests, particularly those related to vibration.

About NASA-ISRO Synthetic Aperture Radar (NISAR)

  • NISAR is a low-earth orbit observatory being jointly developed by ISRO and NASA.
  • It is expected to launch from the Satish Dhawan Space Centre at Sriharikota on board an ISRO Geosynchronous Satellite Launch Vehicle Mark-II (LVM-2).
  • The mission has a three-year duration and will survey all of the earth’s land and ice-covered surfaces once every 12 days. This will start after a 90-day satellite commissioning period.

 

Significance of NISAR

  • It will provide spatially and temporally consistent data for understanding changes in the planet’s ecosystems, ice mass, vegetation, biomass, sea-level rise, groundwater, and natural hazards.
  • NISAR will reveal the dynamics of carbon storage and uptake in wooded, agricultural, wetland, and permafrost ecosystems and the response of ice sheets to climate change, and the interaction of sea ice and climate.
  • The satellite is equipped with a synthetic aperture radar in two frequencies and an antenna reflector. 
  • In all, NISAR is the size of a SUV with a mass of 2.8 tonnes, and will be powered by solar panels.

 

Conclusion

NISAR will represent a new level of capability for Earth observation missions and it is expected to provide crucial insights into climate change, carbon dynamics, and various Earth processes.
