NASA and ISRO satellite to watch the Earth gets one step closer to launch
NISAR, short for NASA-ISRO Synthetic Aperture Radar, is all set to ship out to its last stop before launching into orbit. Before its departure, members of the media got a chance to see NISAR's advanced radar instruments up close on February 3 in a clean room at NASA's Jet Propulsion Laboratory (JPL) in Southern California. "It's nearly time for the scientific heart of NISAR – short for NASA-ISRO Synthetic Aperture Radar – an Earth science satellite being jointly built by NASA and the Indian Space Research Organisation, to ship out to its last stop before launching into orbit: southern India," NASA said in a report.“This marks an important milestone in our shared journey to better understand planet Earth and our changing climate,” JPL Director Laurie Leshin said. “NISAR will provide critical information on Earth's crust, ice sheets, and ecosystems.
By delivering measurements at unprecedented precision, NISAR's promise is new understanding and positive impact in communities.
Our collaboration with ISRO exemplifies what's possible when we tackle complex challenges together,” he added.NISAR will gather radar data with a drum-shaped reflector antenna almost 40 feet (12 meters) in diameter.
It will use a signal-processing technique called interferometric synthetic aperture radar, or InSAR, to observe changes in Earth's land and ice surfaces down to fractions of an inch.Since early 2021, engineers and technicians at JPL have been integrating and testing NISAR's two radar systems – the L-band SAR provided by JPL and the S-band SAR built by ISRO.
