NISAR will gather radar data with a drum-shaped reflector antenna almost 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
The NASA-ISRO Synthetic Aperture Radar (NISAR), an Earth science satellite, that is being jointly built by NASA and the Indian Space Research Organisation (ISRO), got a send-off ceremony in California on Friday before it being shipped out to India.
"This satellite is going to be a phenomenal outcome of India-US collaboration, to entire globe. The integration of payload completed, now we have flagged off the satellite to India for further integration & to get ready for its launch next year," S Somanath, Chairman, ISRO, told ANI.
The NISAR will help study Earth’s land and ice surfaces in greater detail.
S. Somanath has visited NASA’s Jet Propulsion Laboratory (JPL) in US's California state on Friday to oversee the final electrical testing of the NISAR satellite before being shipped to India.
"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,” Somanath said during the formal send-off ceremony at the JPL.
The SUV-size payload will be moved into a special cargo container for a 14,000-kilometer flight to the U R Rao Satellite Centre in Bengaluru later this month.
ISRO and NASA joined hands in 2014 to build the 2,800 kg satellite. In March 2021, ISRO sent its S-Band SAR payload developed in India to NASA for integration with the L-Band payload built by JPL.
"This marks an important milestone in our shared journey to better understand planet Earth and our changing climate. NISAR will provide critical information on Earth’s crust, ice sheets, and ecosystems,” JPL Director Laurie Leshin said.
According to ISRO chief, NISAR spacecraft will be integrated into the satellite bus at the U R Rao Satellite Centre for launch within the next year.
“This is one of the most complex satellites. The elements that are built by JPL are excellent,” Somanath said.
What NISAR will do
NISAR will gather radar data with a drum-shaped reflector antenna almost 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.
The satellite will help researchers detect slow-moving variations of a land surface that can precede earthquakes, landslides, and volcanic eruptions.
Data about such movements could help communities prepare for natural hazards such as the Joshimath land subsidence.
Measurements of melting sea ice and ice sheets will improve understanding of the pace and impacts of climate change, including sea level rise.
Over the course of its three-year prime mission, the satellite will observe nearly the entire planet every 12 days, making observations day and night, in all weather conditions.
