Eye in the sky: Nasa-Isro joint mission NISAR to launch on Wednesday
The imaging technology in Nisar will be able to provide very high-resolution data on changes as small as one centimetre in size on Earth's surface India is poised to script yet another history in the space sector through the launch of the Nisar (Nasa-Isro Synthetic Aperture Radar) mission, a collaboration between the National Aeronautics and Space Administration (Nasa) and the Indian Space Research Organisation (Isro), from Sriharikota in Andhra Pradesh on Wednesday. It is touted as the most expensive Earth observation satellite to date. The imaging technology in Nisar will be able to provide very high-resolution data on changes as small as one centimetre in size on Earth's surface. This will also democratise space sector data by providing free access to the research community. Scaling new heights Key highlights of the mission September 30, 2014: Isro and Nasa signed the deal for the Nisar mission July 30, 2025: Set to launch the satellite aboard the GSLV-Mk II rocket from Sriharikota, Andhra Pradesh, at 5:40 pm $1.5 billion: Total investment in the mission ₹469.4 crore: India's share 2,392 kg: Weight of Nisar What will Nisar do? According to Nasa, it will collect information about our planet's environment It will scan nearly all of Earth's land and ice surfaces twice every 12 days, providing insights into the expansion and contraction of ice sheets, sea ice, and glaciers, the deformation of its crust due to natural hazards, as well as natural and human changes to Earth's terrestrial ecosystems It will help in detecting volcanic changes, landslides, and climate change by taking images of the Earth 24 hours a day These measurements will be carried out by two radar systems — an L-band system built by the Jet Propulsion Laboratory in California, and an S-band system constructed by Isro's space applications centre in Ahmedabad Nisar is the first satellite to carry two radars working at two different frequencies The mission also marks the first hardware collaboration on an Earth-observing mission between the two space agencies. It will use SweepSAR technology for wide-area observation For the first time, a Nasa payload is being launched aboard India's GSLV (Geosynchronous Satellite Launch Vehicle) GSLV is deployed for a sun-synchronous orbit (SSO), which is traditionally a terrain of PSLV GSLV-F16 will put the satellite in a 734 km sun-synchronous orbit Other space cooperations in the pipeline 61: Number of countries with which India has so far signed space cooperative documents. A similar deal was also signed with five multilateral bodies.

"The Earth observation satellite jointly developed by ISRO and NASA will be sent into space on July 30 by the GSLV-F16 rocket made in India," Indian Space Research Organisation chairman V Narayanan said. It will be launched at a distance of 740 km. It can take pictures of the earth 24 hours a day in all weather conditions and the satellite can detect landslides, aid in disaster management and monitor climate change, he said while speaking to reporters at the airport here on Sunday night. "The satellite will benefit India, the US and the entire world... it is also crucial for monitoring earth's natural resources," he added.

NISAR Will Help Global Community Monitor Earth Changes: ISRO Chairman V Narayanan
The highly anticipated NISAR (NASA-ISRO Synthetic Aperture Radar) mission is set to launch on July 30 at 5:40 PM from Sriharikota aboard the GSLV-F16 rocket. Developed through over a decade of collaboration between ISRO and NASA's Jet Propulsion Laboratory, NISAR is the first Earth observation mission to carry a dual-band radar system (NASA's L-band and ISRO's S-band). It aims to revolutionize the way we monitor Earth's land, ice, and natural disasters. The satellite, weighing 2,392 kg, will use SweepSAR technology to capture high-resolution, all-weather data every 12 days. This marks a milestone as the 102nd launch from Indian soil and will significantly benefit global scientific and disaster mitigation efforts.#nisar #isro #nasa #gslvf16 #earthobservation #radarsatellite #spacecollaboration #naturaldisasters #satellitelaunch #indiaspace #sweepsar #isronasa #nasaisro #spaceinnovation Read More

‘One mission to watch Earth': ISRO-NASA's joint satellite NISAR set for July 30 launch
The Indian Space Research Organisation (ISRO) on Sunday stated that the upcoming launch of NISAR, the first joint Earth observation satellite by ISRO and NASA, will mark a key milestone in Earth observation technology. The NISAR mission's primary objectives are to study land & ice deformation, land ecosystems, and oceanic regions in areas of common interest to the US and Indian science communities.(X/@isro) NISAR will be launched from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, on July 30 at 17:40 IST. NISAR is the first mission of its kind, jointly developed by ISRO and NASA. It is an L- and S-band, global, microwave imaging mission, with the capability to acquire fully polarimetric and interferometric data, as per an official statement from ISRO. The unique dual-band Synthetic Aperture Radar of NISAR employs the advanced, novel SweepSAR technique, which provides high-resolution and large-swath imagery. NISAR will image the global land and ice-covered surfaces, including islands, sea-ice and selected oceans, every 12 days. The NISAR mission's primary objectives are to study land & ice deformation, land ecosystems, and oceanic regions in areas of common interest to the US and Indian science communities.

As per the statement, it will also help characterise land surface deformation related to seismicity, volcanism, landslides, and subsidence & uplift associated with changes in subsurface aquifers, hydrocarbon reservoirs, etc. "One mission to watch Earth. #ISRO #NASA builds, Earth benefits. This marks a key milestone in Earth observation technology. Stay tuned as we bring you closer to the mission that watches our world," ISRO sais in a post on X. "The Spacecraft is built around ISRO's I-3K Structure. It carries two major Payloads viz., L & S- Band Synthetic Aperture Radar (SAR). The S-band Radar system, data handling & high-speed downlink system, the spacecraft and the launch system are developed by ISRO. The L-band Radar system, the high-speed downlink system, the Solid-State Recorder, the GPS receiver, and the 9 m Boom hoisting the 12m reflector are delivered by NASA. Further, ISRO takes care of the satellite commanding and operations; NASA will provide the orbit manoeuvre plan and RADAR operations plan. NISAR mission will be aided with ground station support from both ISRO and NASA for downloading of the acquired images, which, after the necessary processing, will be disseminated to the user community," the statement added. The data acquired through S-band and L-band SAR from a single platform will help scientists understand the changes happening to Planet Earth. The complex payloads and mainframe systems have been designed, developed, qualified and realised over a period of 8 to 10 years. "The S- Band SAR and L- Band SAR were independently developed, integrated and tested at ISRO and JPL/NASA respectively. The Integrated Radar Instrument Structure (IRIS), consisting of S - Band and L - Band SAR and other payload elements were intergrated and tested at JPL/NASA and delivered to ISRO," it stated. Mainframe satellite elements and payloads were assembled, integrated and tested at URSC/ISRO. The mission phases can be broadly classified into: Launch phase, Deployment Phase, Commissioning Phase and Science Phase. NISAR will be launched onboard the GSLV-F16 launch vehicle on July 30, 2025 from ISRO's Satish Dhawan Space Centre (SDSC), also referred to as Sriharikota High Altitude Range (SHAR), located in Sriharikota on the southeast coast of the Indian peninsula. It hosts a 12m dia large reflector which shall be deployed in-orbit 9m away from the satellite by a complex multistage deployable boom designed and developed by JPL/NASA. The first 90 days after launch will be dedicated to commissioning, or In-Orbit Checkout (IOC), the objective of which is to prepare the observatory for science operations. Commissioning is divided into sub-phases of initial checks and calibrations of mainframe elements followed by JPL engineering payload and instrument checkout. The science operations phase begins at the end of commissioning and extends till end of mission life. During this phase, the science orbit will be maintained via regular maneuvers, scheduled to avoid or minimize conflicts with science observations. Extensive calibration and validation (CalVal) activities will take place. The observation plan for both L and S-band instruments, along with engineering activities (e.g., maneuvers, parameter updates, etc.), will be generated pre-launch via frequent coordination between JPL and ISRO, the statement added.
