679: OP SINDOOR: ASIM MUNIR – SWORD OF HONOUR TO DISGRACING THE SWORD

 

My Article was published on “The Eurasian Times” website on 12 Jun 25.

 

Syed Asim Munir Ahmed Shah, once celebrated as a decorated and promising officer of the Pakistan Army, has emerged as a deeply polarising figure. His career, which began with distinction marked by the rare honour of winning the Sword of Honour as an Officers Training School (OTS) graduate, now faces harsh criticism amid accusations of ideological zealotry, political manipulation, and strategic failures. The transformation from a respected military leader to one accused of “disgracing the sword” is a compelling narrative that encapsulates the complexities and contradictions of Pakistan’s civil-military relations, the role of religious ideology in the armed forces, and the nation’s fraught political landscape.

 

Early Life.  Born in 1968 in Rawalpindi, Pakistan, Asim Munir came from a family with deep religious roots. His father, Syed Sarwar Munir, was a school principal and an imam at Masjid-al-Quraish in Rawalpindi’s Dheri Hassanabad, delivering Friday sermons that likely influenced Munir’s worldview. Unlike many of his peers from elite military families, Munir’s background was modest, with his family having migrated from Jalandhar, India, during the 1947 partition. His early education at the Markazi Madrasah Dar-ul-Tajweed, an Islamic seminary, instilled a strong religious foundation, significantly shaping his leadership style and raising concerns about religious ideology’s influence in the military.

 

Entry and Military Career.  Unlike many senior officers who rose through the prestigious Pakistan Military Academy (PMA) ranks, Munir was commissioned via the Officers Training School (OTS) in Mangla, an alternative path often viewed as less prestigious. He graduated in 1986, earning the Sword of Honour for his exceptional performance. Commissioned into the 23rd Battalion of the Frontier Force Regiment, he quickly established himself as a promising officer. His career included diverse roles, such as serving as a military attaché in Saudi Arabia, where he memorised the Quran, earning the title of Hafiz-e-Koran, and commanding troops in strategic locations. Munir’s academic credentials are equally impressive, with an MPhil in Public Policy and Strategic Security Management from the National Defence University in Islamabad, alongside training at military institutions in Japan and Malaysia.

 

Rise in the Pakistan Army and Governance. Several high-profile intelligence and command assignments marked Munir’s career. He served as Director-General of Military Intelligence (MI) and later as head of the Inter-Services Intelligence (ISI). However, his term as ISI chief was short-lived, reportedly due to differences with then-Prime Minister Imran Khan, especially over corruption reports implicating the latter’s close aides. This fallout would later shape Munir’s implicit role in the military’s manoeuvring to oust Khan from power. Munir also served as commander of the Force Command Northern Areas (FCNA) in Gilgit-Baltistan and the XXX Corps in Gujranwala. By 2021, he had become Quartermaster General at GHQ Rawalpindi, a key logistical and administrative post. On November 29, 2022, Munir was appointed Chief of Army Staff, becoming the first Hafiz-e-Quran to lead the Pakistan Army. His selection came amid intense political turmoil, and his tenure immediately saw an aggressive consolidation of military influence over civilian institutions. This aggressive consolidation could weaken civilian governance structures and entrench military control in Pakistan’s political landscape. Munir became the central figure in Pakistan’s governance, overshadowing the Prime Minister and the judiciary in decision-making.

 

My Way or the Prison Way: Vindictive Attitude. Former Prime Minister of Pakistan Imran Khan has been imprisoned since August 2023. He claims that Munir harbours personal animosity, stemming from Khan’s decision to remove him as ISI chief in 2019. Khan also alleges that Munir has retaliated by targeting his wife, Bushra Bibi, leading to her 14-month detention under harsh conditions, including solitary confinement and restricted family access. Khan’s narrative, amplified by PTI supporters and a Times Square billboard campaign branding Munir a “Fraud Marshal,” portrays the general as orchestrating a broader crackdown on PTI to suppress dissent. Khan’s calls for judicial inquiries into these actions face challenges from a judiciary he claims is aligned with the military. The critics see a pattern of politically motivated persecution, highlighting the highly vindictive character of Munir.

 

‘Jihadi Mullah General’ with Religious Ideology. Munir’s worldview blends military strategy with Islamic theology, reminiscent of General Zia-ul-Haq’s Islamisation policies in the 1970s and 1980s. He overtly infuses religious ideology into military affairs. In a speech to a grand jirga in Peshawar, Munir explicitly stated that the Pakistan Army operates under the principles of “imaan, taqwa, and jihad fi sabeelillah.” He declared, “We are waging jihad in the path of Allah and success will be ours, Inshallah.” These statements are more in line with militant organisations than modern militaries. Munir’s rhetoric has emboldened radical groups and blurred the line between conventional military operations and religious militancy. The term ‘jihadi general’ began to circulate in international media and think tanks, raising concerns about Pakistan’s nuclear command under such ideological leadership. Internally, his policies led to greater appeasement of hardline clerics and religious political factions, weakening Pakistan’s secular democratic institutions.

 

Mullah-Military Alliance Doctrine. Munir’s speeches frequently invoke the two-nation theory, emphasising irreconcilable differences between Muslims and Hindus. On April 16, 2025, addressing a Pakistani diaspora audience in Islamabad, he stated, “Our forefathers believed we are different from the Hindus in every aspect of life. Our religions, customs, traditions, thoughts, and ambitions differ.” He described Kashmir as Pakistan’s “jugular vein,” a phrase perceived as a signal to terror proxies, preceding the April 22 Pahalgam attack that killed 26 civilians. Munir’s ideology aligns with a mullah-military alliance, where the army positions itself as the defender of Pakistan’s ideological frontiers, not just its borders. His leadership has seen the military provide state funerals for senior terrorists and align rhetoric with groups like Lashkar-e-Taiba and Jaish-e-Mohammed, raising concerns about state-sponsored terrorism. Unlike his predecessor Bajwa, who advocated for geo-economics and a 2021 ceasefire with India, Munir has not uttered a word of peace, focusing instead on jihadist rhetoric and military escalation. His strained relations with Indian leadership and refusal to engage diplomatically contrast with past generals like Zia-ul-Haq and Pervez Musharraf, who maintained channels with Indian counterparts. The long-term effects of this shift in policy could lead to increased tensions with India and further destabilisation within Pakistan as the military’s focus shifts from conventional defence to ideological warfare.

 

Self-Promotion: A Disgrace. During India’s Operation Sindoor in May 2025, Pakistan suffered considerable economic, diplomatic, and military setbacks. Indian airstrikes damaged key military installations, whereas Pakistan’s retaliatory efforts lacked cohesion. Moreover, international isolation deepened due to Pakistan’s perceived role in harbouring terror proxies. Despite this humiliation, Munir self-promoted himself to the rank of Field Marshal, the first such elevation since Ayub Khan in 1965. In the face of significant national challenges, this act of self-promotion raises critical questions about Munir’s leadership and priorities.

 

The “Failed Marshal” Narrative. Munir’s overreach into civil governance is backfiring. His alliance with the fragile coalition government has led to widespread public resentment. The crackdown on political opponents, media censorship, and manipulation of the judiciary has further alienated the citizenry. Economic conditions have deteriorated as foreign investments have dried up. Pakistan’s regional and global reputation has also suffered under Munir’s leadership. Relations with the U.S. have remained lukewarm, while ties with China have grown increasingly transactional. Meanwhile, his harsh rhetoric against India, especially communal remarks linking Hindus to historical grievances, is considered incitement of terror attacks. Domestically, Munir’s legitimacy is being questioned. Civil society has begun to refer to him as a “failed marshal,” suggesting that his promotion was not earned through strategic brilliance but political manipulation. The military’s internal cohesion also reportedly weakened, with factionalism surfacing within the ranks. Some officers allegedly opposed the overt ideological and political shift under Munir’s command.

 

Conclusion. Asim Munir’s career arc, from a Sword of Honour cadet to a disgraced Field Marshal, reflects broader themes in Pakistan’s military and political evolution. His initial promise as a disciplined, devout officer has led to a tenure marked by ideological rigidity, strategic miscalculations, and political entanglement. The sword of honour that once symbolised Asim Munir’s excellence and promise now stands metaphorically tarnished by the controversies of his later years. His transformation, from a highly respected officer to a leader accused of disgracing the military institution, underscores the complex interplay of ambition, ideology, and power in Pakistan’s armed forces.

678: PROJECT KUSHA: INDIA’S INDIGENOUS SKY SHIELD

 

My Article published on “The EurasianTimes” website on 10 Jun 25.

 

 

On June 8, 2025, the Defence Research and Development Organisation (DRDO) chief announced that Project Kusha is equivalent to Russia’s S-500 and surpasses the S-400 in capabilities. This positions it as a “game-changer” for India’s air defence. It is designed to counter stealth jets, drones, aircraft, and Mach 7 anti-ship ballistic missiles with an 80–90% interception success rate.

Project Kusha is an ambitious Indigenous long-range air defence system being developed by the DRDO. It is also known as the Extended Range Air Defence System (ERADS) or Precision-Guided Long-Range Surface-to-Air Missile (PGLRSAM). Project Kusha bridges the gap between the 80 km MR-SAM and 400 km S-400, integrating with systems like Akash and Barak-8.

It is a critical part of India’s self-reliance initiative, “Atmanirbhar Bharat”.  The home-grown solution aims to safeguard India’s airspace from aerial threats by strengthening defences against regional threats, particularly from Pakistan and China. The project has gained attention after the May 2025 India-Pakistan conflict, where air defence systems proved vital against drones and missiles, underscoring the need for indigenous capabilities like Kusha. With a projected deployment timeline of 2028–2029, this system is poised to enhance the operational readiness of the Indian Air Force (IAF) and Indian Navy.

 

System Specifications

Interceptor Missiles. Project Kusha’s core strength lies in its three-tiered interceptor missile system, designed to neutralise various aerial threats at varying ranges. The M1 Interceptor (150 km) missile would target threats like fighter jets, drones, and cruise missiles at shorter ranges. Its compact 250 mm diameter kill vehicle, equipped with a dual-pulse solid rocket motor and thrust vector control, ensures high manoeuvrability and precision, making it ideal for tactical engagements. The M2 Interceptor (250 km) missile with an extended range can engage advanced targets, including airborne early warning and control systems (AEW&CS) and anti-ship ballistic missiles (ASBMs). It shares the M1’s 250 mm kill vehicle, optimised for agility and accuracy against mid-range threats. The M3 Interceptor (350–400 km), the longest-range missile in the system, is designed to counter larger aircraft and potentially short- and medium-range ballistic missiles (SRBMs and IRBMs). It may feature a larger 450 mm diameter kill vehicle to achieve its extended range and enhanced lethality.

Capabilities. These interceptors boast an impressive single-shot kill probability of 85%, which rises to 98.5% when two missiles are launched in salvo mode, five seconds apart. The missiles likely employ hit-to-kill (HTK) technology, relying on kinetic energy rather than explosive warheads, similar to advanced systems like the US THAAD or SM-3. Dual-seeker technology, combining radar and infrared guidance, enhances their ability to track and destroy low-radar-signature targets, such as stealth aircraft and cruise missiles.

Advanced Radar Systems. The effectiveness of Project Kusha hinges on its state-of-the-art radar systems, particularly the Long Range Battle Management Radar (LRBMR), an S-band radar with a detection range exceeding 500 km. This radar can scan 500–600 km into enemy territory, providing early warning against stealth aircraft, drones, precision-guided munitions, and ballistic missiles. The system integrates seamlessly with India’s Integrated Air Command and Control System (IACCS), enabling real-time coordination with other air defence systems, including Akash, MRSAM, and the S-400. For naval applications, the Indian Navy is developing a 6×6-meter radar for its Next Generation Destroyer, four times larger than the radar on the Visakhapatnam-class destroyer, to detect sea-skimming missiles and ASBMs with ranges up to 1,000 km.

Multi-Layered Defence Architecture. Project Kusha is designed as a multi-layered air defence system. It provides strategic and tactical cover for critical infrastructure, military bases, and urban centers. The system’s versatility allows it to counter various threats, from low-flying cruise missiles to high-altitude aircraft and limited ballistic missile threats. By integrating with India’s Ballistic Missile Defence (BMD) program, including the AD-1 and AD-2 interceptors, Project Kusha forms a robust shield against both conventional and strategic threats.

Technological Innovations. Project Kusha incorporates cutting-edge technologies to ensure operational superiority:-

    • AI-Enabled Decision Support. The system may leverage artificial intelligence to coordinate intercepts, process real-time data from satellites, radars, AWACS, and UAVs, and optimise target engagement.
    • Dual-Seeker Technology. Combining radar and infrared seekers enhances the system’s ability to track and destroy stealthy or low-observable targets.
    • Compact Design. The M1 and M2 interceptors’ 250 mm diameter kill vehicles are notably smaller than comparable systems like the US SM-2 or SM-6, showcasing DRDO’s innovative approach to missile design.

 

Comparison with Global Systems

 

S-400 Triumf (Russia). The S-400 can engage 36 targets simultaneously at a range of 400 km. Project Kusha aims to match this range with its M3 interceptor and offers better integration with India’s defence architecture, reducing reliance on foreign maintenance and support.

Patriot (USA). While the Patriot is a proven system, Kusha’s lower cost and indigenous design provide a tailored alternative for India’s needs, with potential for greater scalability.

David’s Sling and Iron Dome (Israel). Although similar in some aspects, such as dual-seeker technology, Kusha’s M2 and M3 missiles offer longer ranges and limited BMD capabilities, unlike David’s Sling’s focus on shorter-range threats. The Iron Dome is optimised for short-range rocket interception, while Kusha targets long-range strategic threats, making it more comparable to the S-400 or Patriot.

 

Project Details & Development Journey

Approval and Funding. In May 2022, the Cabinet Committee on Security (CCS) approved the development of Project Kusha. In September 2023, the Ministry of Defence granted the Acceptance of Necessity (AoN) for procuring five IAF squadrons at an estimated cost of ₹21,700 crore (approximately US$2.6 billion). This investment reflects India’s commitment to building a self-reliant defence ecosystem that addresses modern threats.

Key Partners. The DRDO is leading the Project Kusha, with Bharat Electronics Limited (BEL) playing a pivotal role in developing critical subsystems like radars and battle management systems. The Defence Research and Development Laboratory (DRDL) is responsible for designing the interceptor missiles, while the Research Centre Imarat (RCI) focuses on advanced seeker technology. Collaboration with private industry partners is expected to accelerate development and production, aligning with India’s push for public-private partnerships in defence.

Timeline. As of May 2025, the DRDO has reportedly completed the design phase, with development of critical components underway. BEL aims to complete a prototype within 12–18 months (by November 2026–May 2027). The user trials are expected to last 12–36 months, paving the way for operational deployment by 2028–2029.

 

Strategic Significance

Self-Reliance and Cost-Effectiveness. Project Kusha is a cornerstone of India’s Atmanirbhar Bharat initiative, reducing dependence on foreign systems like the S-400, which faced delivery delays due to the Russia-Ukraine conflict. At ₹21,700 crore for five IAF squadrons, it is significantly more cost-effective than the $5.25 billion deal for five S-400 units, offering comparable capabilities tailored to India’s operational needs. This cost advantage enhances India’s ability to scale its air defence infrastructure without straining its defence budget.

Regional Deterrence.  With China and Pakistan modernising their air forces and missile arsenals, Project Kusha strengthens India’s deterrence posture. Its ability to counter stealth aircraft, cruise missiles, and ASBMs addresses emerging threats in the Indo-Pacific, particularly China’s growing naval and missile capabilities. The system’s integration with the IACCS ensures a cohesive defence network, enabling rapid response to multi-domain threats and enhancing India’s strategic autonomy.

Export Potential. Project Kusha’s advanced technology and competitive pricing position India as a potential global air defence market player. Countries seeking alternatives to Western and Russian systems may find Kusha attractive, boosting India’s defence exports and geopolitical influence. Success in this arena could elevate India’s status as a defence technology provider, complementing its exports like the BrahMos missile.

 

Challenges and Considerations

Technical Challenges. Achieving the claimed ranges with compact interceptors, particularly the 150 km M1, has raised scepticism due to its small size compared to US SM-2 or SM-6 systems. Ensuring reliability and accuracy against stealthy and hypersonic threats will require rigorous testing and validation.

Development Timeline. The 2028–2029 deployment target is ambitious, given the complexity of integrating advanced radars, AI systems, and interceptors. Delays in prototype development or user trials could push back operational readiness, as seen in past DRDO projects.

System Integration. Seamless integration with existing systems (Akash, MRSAM, S-400) and future systems (AD-1, AD-2) is essential for a cohesive air defence network. Any interoperability issues could undermine the system’s effectiveness and delay deployment.

International Competition. India will face stiff competition from established players like the US, Russia, and Israel in the global air defence market. Demonstrating technological superiority and reliability will be critical for export success and domestic adoption.

 

Future Phases

Naval Integration. The Indian Navy plans to deploy the M1 and M2 interceptors on next-generation surface combatants, such as destroyers, to counter ASBMs and other maritime threats. The enhanced naval radar system will provide 360-degree coverage, enabling early detection and interception of sea-skimming missiles. This integration underscores Project Kusha’s role in strengthening India’s maritime security, particularly in the Indo-Pacific region, where threats like China’s DF-21D “carrier-killer” missiles pose significant challenges.

Future Enhancement. Project Kusha is the first phase of a multi-phase program. Phase II aims to develop interceptors with ranges exceeding 400 km and anti-hypersonic capabilities, potentially rivalling Russia’s S-500 system. This long-term vision underscores India’s ambition to remain at the forefront of air defence technology, addressing future threats like hypersonic missiles and advanced stealth platforms.

 

Conclusion

Project Kusha represents a monumental leap in India’s quest for self-reliance in defence technology. It promises to deliver a versatile, multi-layered air defence shield capable of countering diverse threats by combining advanced interceptors, long-range radars, and AI-driven systems. A cost-effective price tag and a focus on indigenous innovation strengthen India’s strategic autonomy and position the country as a potential leader in the global defence market. However, overcoming technical challenges and meeting the ambitious 2028–2029 timeline will be critical to realising its full potential. As India advances toward operational deployment, Project Kusha is a testament to its growing technological prowess and commitment to safeguarding its skies.

677: NISAR: MAPPING THE FUTURE AND REVOLUTIONISING CLIMATE AND DISASTER INTELLIGENCE

 

My article was published in the Jun edition of the

News Analytics Journal

 

 

In an era where climate change, natural disasters, and ecological degradation are becoming more pressing global concerns, advanced space-based Earth observation has emerged as a vital tool. The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a landmark collaboration between the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO).

NISAR represents the most advanced dual-frequency radar satellite ever developed for civilian use. Once operational, NISAR will monitor Earth’s land and ice surfaces with high precision. It will capture surface movements down to fractions of an inch, aiding in studying tectonic shifts, glacier dynamics, forest health, and infrastructure stability.​ It can transform how we understand and respond to changes on Earth’s surface, ranging from glacial movements to forest biomass, from seismic activity to urban land subsidence.

The latest update on the NASA-ISRO Synthetic Aperture Radar (NISAR) mission indicates that the launch is scheduled for late May to June 2025, a shift from the anticipated March 2025 timeline. This delay, caused by thermal coating issues with the 12-meter radar antenna reflector, was resolved by October 2024. Despite the delay, the mission’s objectives and timeline remain intact. Final integration and testing are underway at ISRO’s facilities in Bengaluru. The satellite is expected to be transported to the Satish Dhawan Space Centre in the coming weeks to prepare for its launch aboard a GSLV Mark II rocket.​

 

NISAR Project: Collaborative Effort

 

Genesis. The NISAR mission concept emerged from NASA’s 2007 Decadal Survey, which called for advanced SAR data to address gaps in Earth science. Formalised in 2014 with a partnership agreement, the project has progressed through rigorous design, testing, and integration phases. NASA’s Jet Propulsion Laboratory (JPL) and ISRO’s Space Applications Centre have worked closely to refine the mission’s science plan and hardware.

Project Details. The NISAR mission is designed to provide unprecedented global radar imagery using L-band and S-band synthetic aperture radars. NASA has provided the L-band radar system, high-rate communication subsystem, GPS receivers, and payload data systems. ISRO is contributing the S-band radar, satellite bus, and launch services via the GSLV Mk II from the Satish Dhawan Space Centre. The satellite will be placed in a sun-synchronous polar orbit at about 747 kilometres and revisit the exact location on Earth every 12 days. The SAR payload will produce radar images with a resolution of 5–10 meters and a swath of 240 kilometres, enabling wide-area monitoring of Earth’s surface with high precision. The unique dual-band system of NISAR allows it to penetrate vegetation, ice, and soil more accurately than single-frequency satellites, making it a game-changer in Earth observation. The L-band is particularly effective for tracking subsurface movement and biomass, while the S-band is more sensitive to finer surface features.

Collaboration. The NISAR partnership exemplifies international cooperation in space exploration. NASA’s investment, estimated at $1.118 billion, covers the L-band radar and critical subsystems, while ISRO’s contribution, approximately ₹788 crore ($92 million), includes the S-band radar, spacecraft bus, and launch services. This division of responsibilities optimises costs and expertise, building on NASA’s legacy of SAR missions (e.g., SEASAT in 1978) and ISRO’s advancements in satellite technology (e.g., the Chandrayaan missions). The collaboration extends beyond hardware. Joint workshops, working groups, and the NISAR Utilisation Programme announced by ISRO in July 2023 engage the global scientific community, fostering data analysis and application development. The mission’s open data policy aligns with the principles of transparency and collaboration, setting a precedent for future NASA-ISRO endeavours, including potential Mars exploration missions.

 

Mission Objectives and Scientific Impact

NISAR’s primary goal is to make global measurements of land surface changes, detecting movements as small as a centimeter. By mapping the globe every 12 days, the satellite will generate spatially and temporally consistent data, offering insights into complex Earth processes. Its objectives span three key domains: deformation, ecosystem structure, and ice dynamics. NISAR will monitor seismic zones, volcanic activity, and landslide-prone areas for deformation, providing early warning signs for natural disasters. In ecosystem studies, it will track forest extent, vegetation biomass, and agricultural patterns, aiding sustainable resource management. NISAR will measure glacier flow rates and ice-sheet stability for ice dynamics, contributing to our understanding of climate change and sea level rise.

All NISAR data will be freely available within one to two days of observation or hours for emergencies like natural disasters. This accessibility and NISAR’s high-resolution imagery (5-10 meters) will empower scientists, policymakers, and disaster response teams worldwide. The data can enhance infrastructure monitoring, improve agricultural management, and inform rapid disaster response, potentially saving lives and property. The open data policy also encourages collaboration and innovation, allowing for the development of new applications and tools to further leverage NISAR’s capabilities.

 

Applications

Natural Disaster Monitoring and Response. NISAR will be critical in mapping the aftermath and precursors of earthquakes, floods, volcanic eruptions, and landslides. The radar’s ability to detect minute ground deformations will help forecast and emergency response, reducing the human and economic cost of such events.

Climate Change Observation. The satellite will track ice sheet movement in Antarctica and Greenland, glacial retreat in the Himalayas, and coastal subsidence, all critical indicators of global climate change. NISAR data will also assist in modelling sea level rise and understanding the behaviour of the permafrost regions, which store vast amounts of greenhouse gases.

Agriculture and Forestry. NISAR’s radar can estimate biomass and crop yield, making it invaluable for food security planning and carbon stock assessment. It will monitor deforestation, forest degradation, and land-use changes, helping countries meet international commitments such as those under the Paris Agreement and REDD+ initiatives.

Urban Infrastructure Monitoring. Urban planners and disaster mitigation agencies can use NISAR to monitor growing cities’ subsidence, groundwater depletion, and infrastructure stress. Its precise deformation measurements can help predict building collapses, dam failures, and roadbed weaknesses.

Scientific and Tectonic Research. Scientists will use NISAR to understand better plate tectonics, fault line dynamics, and volcano formation. The L-band radar, in particular, is ideal for detecting ground movements as small as a few millimetres, critical for early warnings in earthquake-prone regions.

Strategic Significance

The NISAR mission is a scientific milestone and a strategic symbol of the growing India-US partnership in space technology. It reflects significant technological trust and collaborative capacity-building, especially as China expands its space and Earth observation programs.

For India, the mission provides access to advanced radar imaging technology, enhances its global space diplomacy profile, and contributes to developing disaster management and environmental monitoring capacity. For the U.S., NISAR extends Earth observation to low-latitude and tropical regions, which are difficult to monitor from NASA’s polar-focused satellites.

 

Conclusion

NISAR stands at the intersection of science, diplomacy, and strategic policy. As the world’s most advanced Earth-observing radar satellite, it will provide a detailed, dynamic picture of the planet’s changing surface. Whether helping farmers optimise irrigation, supporting relief efforts after natural disasters, or aiding climate scientists in tracking global warming, NISAR will become an indispensable part of humanity’s Earth-monitoring infrastructure.
