NISAR could've saved lives in Uttarakhand cloudburst
BENGALURU: Had the July 30-launched NASA-ISRO Synthetic Aperture Radar (NISAR) satellite been operational now, several lives would have been saved through evacuation ahead of the killer cloudburst and flash floods that almost wiped out Dharali village in Uttarkashi district of Uttarakhand on Tuesday afternoon. The 2,393 kg NISAR's unique dual-band synthetic aperture radar (SAR) will employ advanced, novel SweepSAR technique, to provide high resolution and large swath imagery, and will scan the entire globe to provide all-weather, day & night data at 12-day intervals. NISAR can detect even small changes in the Earth's surface such as ground deformation, storm characterization, ice sheet movements and sea ice classification, changes in soil moisture, mapping & monitoring of surface water resources, vegetation dynamics, shoreline monitoring and disaster response. NISAR, carrying the dual-band SAR involving L- & S-Band SAR, is a global, microwave imaging satellite capable of acquiring fully polarimetric and interferometric data. While the S-band radar system, data handling and high-speed downlink system, the spacecraft and the launch system are developed by ISRO, the L-band radar system, high speed downlink system, the solid-state recorder, GPS receiver, the 9-metre boom hoisting the 12-metre unfurlable reflector, are delivered by NASA. A senior official from the regional centre of ISRO's National Remote Sensing Centre – which will collect the S-Band data that NISAR's radar will capture and relay – said, 'Although our work of analyzing the satellite images will increase, getting accurate advance information will be crucial. While the existing satellites and various government departments do share advanced information and alerts, the NISAR data will be several steps ahead. It will share better quality and high resolution images of the same location – irrespective of weather and sunshine – of the same location, twice every 12 days. This will help in knowing dangers and issuing alerts to the district and village administrations in advance.'

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. Trishna mission: Planned earth observation satellite mission by India and France, focusing on thermal infrared imaging for monitoring land and water surface temperatures, scheduled for launch this year

Earth observation NISAR satellite will be launched on Jul 30, says ISRO chairman
The unique Earth observation satellite NASA-ISRO Synthetic Aperture Radar (NISAR) will be launched through the GSLV-S16 on July 30, said ISRO chairman V 2,392 kg, NISAR is a unique Earth observation satellite and the first to observe the Earth with a dual-frequency Synthetic Aperture Radar (NASA's L-band and ISRO's S-band) both using NASA's 12m unfurlable mesh reflector antenna, integrated to ISRO's modified 13k satellite will observe earth with a swath of 242 km and high spatial resolution, using SweepSAR technology for the first time, according to the space will be launched from the Satish Dhawan Space Centre, Sriharikota. "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. On Gaganyaan, India's human spaceflight Mission, Narayanan said a humanoid, called Vyommitra, will be sent into space in December this year. Once it proved to be successful, two other uncrewed missions would be launched next year. Following the success, the Gaganyaan Mission will be launched in March 2027 as Prime Minister Narendra Modi has said.

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
