The indian area studies company (ISRO), in partnership with NASA, has effectively launched the NISAR (NASA-ISRO synthetic Aperture Radar) satellite tv for pc, a c Earth commentary undertaking, from Sriharikota on Wednesday.
Appreciably, the lift-off happened on July 30, 2025, at 17:40 IST from the satish dhawan space centre in Sriharikota, Andhra Pradesh.
This landmark task, over a decade inside the making, represents a blended investment of more than $1.five billion by means of the indian and American space corporations.
NISAR turned into deployed into orbit aboard the GSLV-F16 (Geosynchronous satellite release automobile). While such missions are generally done using the PSLV, this marks the primary event a GSLV rocket has placed a satellite tv for pc into a sun Synchronous Polar Orbit.
It's far noteworthy that the NISAR is the primary radar imaging satellite globally to perform with dual radar frequencies, NASA's L-band and ISRO's S-band, permitting it to locate diffused shifts in the world's floor, down to changes as small as a centimetre, in keeping with the 2 space businesses.
"Liftoff! And we've got liftoff! GSLV-F16 has successfully released sporting NISAR," isro introduced on X.
Weighing 2,392 kilograms, the NISAR satellite tv for pc has been efficiently inserted right into a sun-synchronous orbit. It will circle the Earth approximately every 97 mins, shooting exact pictures of land, ice, and select ocean surfaces each 12 days.
Designed with a assignment lifespan of 5 years, NISAR is prepared to deliver essential facts on changes to the Earth's floor with high-quality accuracy.
In advance in the day, isro had posted on X: "release Day has arrived for GSLV-F16 & NISAR. GSLV-F16 is standing tall on the pad. NISAR is ready. Liftoff these days."
Union minister Jitendra Singh hailed the launch, calling it greater than a satellite tv for pc, it represents India's "clinical handshake with the arena."
NISAR's maximum one-of-a-kind function is its twin-band synthetic Aperture Radar, which utilises an revolutionary sweepsar technology. This permits the satellite to provide high-decision photographs over extensive geographic swaths.
ISRO noted that the satellite will map international land masses, ice-covered terrain, sea ice, islands, and pick out ocean areas each 12 days, the use of each L-band (from NASA) and S-band (advanced through ISRO) radars.
The number one desires of the challenge encompass tracking land and ice deformation, analysing ecosystems, and staring at oceanic phenomena of mutual interest to scientists in india and the us.
The preliminary 90 days publish-release will be committed to the In-Orbit Checkout (IOC) segment, at some stage in which the satellite tv for pc's systems could be tested and calibrated before complete medical operations begin.
A amazing thing of the project is its open data policy, all observations made by using NISAR will be freely to be had to the global medical network inside one to 2 days, with close to actual-time get entry to furnished all through emergency conditions.
This mission additionally marks a milestone in microwave imaging, supplying fully polarimetric and interferometric competencies the usage of separate radar frequencies, an unheard of feature in Earth remark satellites.
