India–US ‘scientific handshake' to track disasters, climate via NISAR satellite
'NISAR is not just a satellite; it is India's scientific handshake with the world,' Dr Singh remarked, adding that the NISAR satellite is scheduled for launch on 30 July from Sriharikota.
During a media briefing, Dr Singh explained that NISAR is designed to deliver critical global data related to natural disasters, agriculture, and climate for the benefit of the entire world.
Calling it a global benchmark in Indo-US scientific collaboration, he emphasised that, as the first joint Earth observation mission between ISRO and NASA, the launch will mark a significant milestone in the history of Indo-US space cooperation, as well as in ISRO's broader international engagements.
He further stated that the mission will be launched aboard India's GSLV-F16 rocket. The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite will provide observations that will be made available to policymakers worldwide, aiding in the formulation of more effective responses to challenges posed by climate change.
Dr Singh said the mission embodies Prime Minister Narendra Modi's vision of India becoming a 'Vishwa Bandhu' – a global partner contributing to the collective good of humanity.
'NISAR will not only serve India and the United States but will also provide critical data for countries around the world, especially in areas like disaster management, agriculture, and climate monitoring,' he said.
A key feature of the mission, Dr Singh noted, is that all data generated by NISAR will be freely accessible within one to two days of observation, and in near real-time during emergencies. He said the mission combines the technological expertise of both space agencies.
ISRO, for its part, has contributed the S-Band SAR payload, the spacecraft bus accommodating both payloads, the GSLV-F16 launch vehicle, and all associated launch services.
Weighing 2,392 kg, the satellite will be placed in a sun-synchronous orbit, enabling repeat imaging of the Earth's land and ice surfaces every 12 days.
'It will allow continuous monitoring of ecosystem disturbances and help assess natural hazards such as earthquakes, tsunamis, volcanic eruptions, and landslides,' Dr Singh said.
One of the satellite's most notable capabilities is its ability to track even subtle changes in the Earth's crust and surface movement.
'The data from the satellite will also be used for sea ice classification, ship detection, shoreline monitoring, storm tracking, crop mapping, and changes in soil moisture – all of which are vital for governments, researchers, and disaster management agencies,' he added.

‘NASA is under attack': Massive NASA layoffs see 20% staff fired amid Donald Trump's fund cuts; nationwide protests erupt
Image: Nearly 20% of NASA's workforce — approximately 3,870 employees — have exited the agency following major funding cuts under the Trump administration's plan to downsize federal agencies. The layoffs stem from the Deferred Resignation Program, with officials describing the move as an effort to make NASA 'leaner and more efficient.' The decision has triggered widespread backlash from scientists, engineers, and space policy experts, who warn of serious risks to the agency's future missions. Nationwide protests erupted over the weekend, with current and former employees calling the move a direct threat to America's leadership in space. NASA fires thousands under federal downsizing drive The second round of the Deferred Resignation Program, which closed late Friday, saw roughly 3,000 resignations on top of 870 from the first wave of departures after Trump returned to office. Including regular attrition, NASA's workforce has shrunk from over 18,000 to around 14,000, marking a 20% reduction. Those resigning have been placed on administrative leave until their official exit. The move was orchestrated under the Department of Government Efficiency, currently led by Elon Musk. NASA insists that safety remains a top priority, yet internal experts are raising alarms about the loss of institutional knowledge and highly skilled personnel. With Mars and Moon missions central to the Trump administration's ambitions, critics argue these cuts threaten mission readiness. Former NASA officials and space industry leaders are questioning the agency's capacity to manage complex space programs in the coming years. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Live Comfortably: 60m2 prefabricated bungalow for the elderly in Tebas Pre Fabricated Homes | Search Ads Search Now Undo Protests erupt over 'brain drain' and loss of legacy Protests have broken out in several cities including Houston, Washington D.C., and Cape Canaveral, where current and former NASA staff, union representatives, and supporters gathered to oppose the mass layoffs. A letter titled The Voyager Declaration, signed by hundreds of former employees, warns that irreplaceable expertise is being lost at a critical moment for U.S. space exploration. 'This is not streamlining,' one protestor said, 'this is sabotage.' Doubts over leadership as Trump's NASA pick falters Adding to the turmoil, NASA is still being led by an acting administrator after tech billionaire Jared Isaacman, Trump's initial nominee backed by Elon Musk, was rejected for the role. In the absence of permanent leadership, critics argue that the agency is navigating its most challenging transformation without a clear long-term vision or stable command structure.

Baba Vanga was right? Scientists claim alien ship larger than Manhattan, moving at 1.3 lakh mph, to attack Earth this Nov
Legendary Bulgarian mystic Baba Vanga had reportedly predicted that humanity would make contact with aliens in 2025. But recent scientific claims suggest that contact may come sooner — and far more hostile. According to a report published on July 16 on the preprint server arXiv and cited by the New York Post and South West News Service, a team of scientists has warned that an alien spacecraft may be heading toward Earth — potentially launching an attack as early as this November.

Just a day after its discovery, astronomers confirmed that it originated from outside our solar system. Initial observations suggested it might be a comet, roughly 15 miles in diameter — making it even larger than Manhattan. However, in their paper, researchers Avi Loeb, Adam Hibberd, and Adam Crowl from the Initiative for Interstellar Studies propose that 3I/ATLAS might not be a natural object at all, but rather a piece of extraterrestrial spy technology in disguise. Loeb, a Harvard astrophysicist known for his controversial theory that the 2017 object `Oumuamua could have been an alien reconnaissance probe, argues that 3I/ATLAS displays several unusual characteristics — including a unique trajectory and exceptionally high speed. These anomalies, he suggests, could point to an intelligent origin. Live Events In a blog post, Loeb noted that the object's path through the solar system allows it to pass close to Jupiter, Mars, and Venus — an ideal opportunity, he says, for aliens to covertly deploy surveillance 'gadgets' on these planets. What's more concerning is that when 3I/ATLAS reaches its closest point to the Sun (perihelion) in late November, it will temporarily vanish from Earth's view. Loeb suggests this may be a deliberate move to avoid detection by Earth-based telescopes — possibly the moment when alien technology could be dispatched toward our planet. If 3I/ATLAS is indeed a technological artifact, it may support the "dark forest hypothesis" — the idea that intelligent alien civilizations stay hidden to avoid detection by potential threats. Loeb warns that this situation might not just be surveillance, but a precursor to a potential alien attack , urging that "defensive measures" may need to be considered. Whether this object turns out to be a comet or a cosmic Trojan horse, the scientific world — and the public — will be watching closely as November approaches.

ISRO-NASA Joint Satellite NISAR Set For Launch On July 30 From Sriharikota
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. 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. The joint mission will accomplish multiple tasks, including measuring the woody biomass and its changes, tracking changes in the extent of active crops, understanding the changes in wetlands' extent, and mapping Greenland & Antarctica's ice sheets and the dynamics of sea ice and mountain glaciers. 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 said 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.
