NISAR Mission

India's space agency Indian Space Research Organisation (ISRO) has recently received NASA-ISRO Synthetic Aperture Radar (NISAR) in Bengaluru. 

The handover of the radar is a major milestone in strengthening US-India ties in space collaboration.

The receipt of the radar by ISRO will enhance the space agency’s understanding about the Earth and changing climate. 

NISAR is jointly built by NASA and the Indian Space Research Organisation (ISRO). NISAR is one of its kind joint collaboration between the US and Indian space agencies. NISAR will map the entire globe in 12 days.

The project is billed to be one of the world's most expensive earth imaging satellite.
ISRO and NASA have come together for the launch of first of its kind NASA-ISRO Synthetic Aperture Radar (NISAR) satellite. 

What is L-band SAR in NISAR Mission?
NISAR satellite is basically a dual-frequency RADAR, an L-band 24 centimetre RADAR and S-band 13 centimetre. ISRO is building S-band frequency and the latter is built by NASA.
