A Send-off ceremony of science instrument payload of NISAR held at NASA's Jet
Propulsion Laboratory (JPL) on Feb 3, 2023. Shri S Somanath, Secretary, DOS /
Chairman, ISRO, Sripriya Ranganathan, Indian Ambassador and Deputy Chief of Mission,
officials from ISRO, NASA were present during the ceremony.
NASA-ISRO SAR (NISAR) is a Low Earth Orbit (LEO) observatory being jointly developed
by NASA and ISRO. It carries L and S dual band Synthetic Aperture Radar (SAR), which
operates with Sweep SAR technique to achieve large swath with high resolution data.
The SAR payloads mounted on Integrated Radar Instrument Structure (IRIS) and the
spacecraft bus are together called an observatory
The NISAR observatory carries a 12m wide deployable mesh reflector mounted onto a
deployable 9m boom developed by JPL which shall be used by both-JPL-NASA developed
L-Band SAR payload system and ISRO developed S-Band SAR payload.
“Today we come one step closer to fulfilling the immense scientific potential NASA
and ISRO envisioned for NISAR when we joined forces more than eight years ago,”
Somanath said. “This mission will be a powerful demonstration of the capability of
radar as a science tool and help us study Earth's dynamic land and ice surfaces in
greater detail than ever before.”
Officials from NASA, ISRO, JPL, and the Indian Embassy held a send-off
ceremony before the NASA-ISRO Synthetic Aperture Radar (NISAR) science
instrument payload is transported to southern India for integration with the
spacecraft bus, further testing, and launch in 2024Credits:
