NISAR payload will get conventional send-off at Nasa lab for ultimate journey to India; sat launch in 2024

NEW DELHI: Senior Nasa and Isro officers broke the ceremonial coconut on Friday (native time) on the US area company’s Jet Propulsion Laboratory (JPL) in southern California earlier than the beginning of the 14,000-km ultimate journey of the SUV-size payload for the world’s most costly NISAR satellite tv for pc to India for its launch from Sriharikota. JPL director Laurie Leshin additionally introduced the Isro chairman S Somanath-led Indian delegation with a jar of JPL ”fortunate” peanuts for the final leg of the $1.5 billion Indo-US satellite tv for pc mission earlier than its “launch in 2024”.
Later this month, Nasa officers will transfer the dual-band payload right into a particular cargo container for the flight to Bengaluru’s U R Rao Satellite tv for pc Centre. There it will likely be merged with the spacecraft bus in preparation for its launch from the Indian soil. Since early 2021, engineers and technicians at JPL have been integrating and testing NISAR’s two radar methods – the L-band SAR offered by Nasa’s JPL and the S-band SAR constructed by Isro.


JPL director Leshin stated, “This (send-off) marks an necessary milestone in our shared journey to raised perceive planet Earth and our altering local weather. NISAR will present essential info on Earth’s crust, ice sheets, and ecosystems. By delivering measurements at unprecedented precision, NISAR’s promise is a brand new understanding and a optimistic impression in communities. Our collaboration with Isro exemplifies what’s doable after we deal with advanced challenges collectively.” The Isro chief, Indian ambassador and deputy chief of mission Sripriya Ranganathan, and Nasa officers toured the Excessive Bay 2 clear room, the place engineers had been placing the payload by the ultimate testing. Additionally current was Bhavya Lal, Nasa’s affiliate administrator for expertise, coverage, and technique.
The Isro chairman stated, “At this time we come one step nearer to fulfilling the immense scientific potential Nasa and Isro envisioned for NISAR after we joined forces greater than eight years in the past. This mission might be a strong demonstration of the aptitude of radar as a science device and assist us research Earth’s dynamic land and ice surfaces in larger element than ever earlier than.”
NISAR is a low earth orbit observatory and carries L and S twin band Artificial Aperture Radar (SAR), which operates with Sweep SAR method to realize giant swaths with excessive decision knowledge. Over the course of its three-year prime mission, the satellite tv for pc, which carries a 12m extensive deployable mesh reflector mounted onto a deployable 9m growth, will observe practically the complete planet each 12 days, making observations day and evening, in all climate situations. The satellite tv for pc will assist researchers measure methods by which Earth is continually altering by detecting each delicate and dramatic actions. Sluggish-moving variations of a land floor can precede earthquakes, landslides and volcanic eruptions, and knowledge about such motion might assist nations put together for pure hazards, Nasa stated.
