and Isro could soon start discussing areas of common interest for another joint mission although there's nothing concrete decided at this juncture.
Karen St Germain, Director of Earth Science, Nasa headquarters, answering a question on whether there would be a follow-up mission, said late on Monday: '…We have been so focussed on getting Nisar completed and into orbit and extracting the incredible science and applications from the mission that we don't have a mission lined up at the moment. But I assume we will start talking about common interests on our next mission in the near future.
'
Nasa hinting at a possibility of another joint mission points to a growing alignment between the two space agencies not just in human spaceflight or lunar exploration but also in Earth observation and climate monitoring — areas where both countries see strategic and scientific value.

'We've worked this intimately where they [Isro teams] spent years at our facility and we spent years at theirs,' Phil Barela, Nisar project manager from JPL, said, describing the partnership as deeply integrated.
He noted that while the two agencies often approached problems differently, the teams stayed open-minded and eventually developed a strong working rhythm. 'It is an extremely powerful team at this point and not something we'd trade for the world,' Barela added.
Karen, while recognising the leadership of Isro and JPL team, said building a satellite on opposite sides of the world during a global pandemic was really hard, but it strengthened the relationship with Isro. 'The collaboration, the cooperation, information sharing, and, frankly, joint learning between our two agencies is a foundation that we look forward to continuing to build upon,' Karen said.
Barela added that during the height of Covid, about 65 Isro engineers visited JPL and worked to keep the integration and tests going.
'...And over the last two-and-a-half years, Nasa has sent out over 175 engineers to Isro's facilities to keep the integration and tests going and get us ready for where we stand today and ready for launch.'
Isro cost model different
Financially, Nasa has invested about $1.2 billion over the primary life of the mission. However, Karen refrained from comparing costs directly with Isro, saying the Indian agency follows a different accounting model.
'...So it's really difficult to draw comparisons based on money alone,' Karen noted.
Instead, she highlighted the equitable hardware and operations contributions from both sides. Nasa developed the L-band radar system and related subsystems, while Isro built the spacecraft bus, S-band radar, solar arrays, and is handling launch and mission operations. A standout component of the spacecraft is the nearly 40-foot deployable antenna and boom, an engineering feat integrated across teams.
'This is a completely joint and integrated mission,' Karen said, emphasising that Nisar reflects a level of collaboration that is rare in large-scale satellite missions.

Who is Manjul Bhargava? The Indian-origin math genius nurtured by Harvard, mentored at Princeton
At first glance, Manjul Bhargava's story reads like that of many Indian-origin overachievers in the academic world. But look closer, and his journey reveals a rare blend of intellectual brilliance, deep cultural grounding, and boundary-breaking curiosity. From mastering high school mathematics by the age of 14 to winning the Fields Medal, the most prestigious prize in mathematics, Bhargava has followed an educational path that is both elite and deeply personal. A childhood steeped in math and music Born on August 8, 1974, in Hamilton, Ontario, to Indian parents, Bhargava grew up in Long Island, New York, where his mathematical talents became evident early. His mother, Mira Bhargava, a mathematics professor at Hofstra University, was his first teacher. She introduced him to mathematical ideas not just through textbooks, but through puzzles and patterns. By age 14, Bhargava had completed his school's full curriculum in math and computer science. But he wasn't just a numbers kid. He also studied tabla under masters like Zakir Hussain and learned Sanskrit poetry from his grandfather, Purushottam Lal Bhargava—experiences that shaped his uniquely creative and interdisciplinary way of thinking. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Brain tumor has left my son feeling miserable; please help! Donate For Health Donate Now Undo Harvard : Where talent met opportunity After graduating as valedictorian from Plainedge High School, Bhargava went on to Harvard University, where he earned his AB in mathematics in 1996. Harvard gave him not only academic rigor but also the freedom to explore advanced mathematical research as an undergraduate. His work during this time was already groundbreaking. He discovered new mathematical structures and submitted original research, earning him the 1996 Morgan Prize—the highest award for an undergraduate in mathematics in North America. Princeton: The place that shaped his research identity Bhargava pursued his PhD at Princeton University, where he studied under Sir Andrew Wiles, famed for solving Fermat's Last Theorem. This period proved transformational. His doctoral thesis, Higher Composition Laws , reimagined 200-year-old ideas from Gauss and offered powerful new tools in number theory. Bhargava's work during his PhD not only earned widespread academic acclaim but also set the foundation for a career filled with pioneering discoveries. Princeton recognized his brilliance early and appointed him a tenured full professor by age 29—an extraordinary milestone in academia. A career defined by curiosity and creativity Bhargava's post-doctoral years were marked by rapid-fire breakthroughs. He developed 14 new composition laws, offered new proofs of classical theorems like the 15 and 290 Theorems, introduced the Bhargava factorial, and co-authored proofs that advanced the understanding of elliptic curves—key to both pure mathematics and cryptography. In 2014, he received the Fields Medal for 'developing powerful new methods in the geometry of numbers.' The award confirmed what the math world had long known: Bhargava was not just a gifted problem-solver, but a thinker capable of reshaping entire domains. Bridging worlds: India, the West, and everything in between Although based at Princeton, Bhargava maintains strong ties with India. He holds adjunct appointments at the Tata Institute of Fundamental Research, IIT Bombay, and the University of Hyderabad. His work reflects a global perspective—rooted in Indian tradition, shaped by American education, and respected across continents. He served on the Padma Awards Committee in 2023, highlighting his growing role in shaping Indian scientific policy and recognition. What students can learn from Bhargava's path Manjul Bhargava's life is a lesson in how education is not just about prestige—it's about passion. From Harvard's lecture halls to Princeton's research labs, what carried him forward was not just intelligence, but the joy of exploration. He blended disciplines, embraced his heritage, and never lost his sense of wonder. For students in India and across the globe, Bhargava's path is an inspiring reminder: deep curiosity, nurtured by strong mentorship and an open mind, can lead not only to personal success but to discoveries that change the world.

Travelling to hill stations for fresh air? Toxic Himalayan clouds can damage lungs, kidneys and liver or give cancer
In the pristine altitudes of the Himalayas and the lush folds of the Western Ghats, clouds were once considered nature's purest gift, and symbols of untouched serenity and sources of sacred rain. However, this long-held belief is now under threat, as per the reports. A new scientific study, as reported in PIB , has revealed that these clouds are quietly carrying something far more sinister. It reported that the clouds are responsible for ferrying toxic heavy metals silently from polluted lowlands to some of the highest, most fragile ecosystems. These findings shatter the myth of 'clean' mountain rain, and also ring alarm bells for human health, which can lead to potential risks ranging from development disorders to cancer. Researchers from the Atmospheric Sciences Division of the Bose Institute, an autonomous body under the Department of Science and Technology (DST), have found that clouds drifting over the Eastern Himalayas and the Western Ghats are now acting as transport vehicles for toxic heavy metals, lifted from the polluted lowlands. These non-precipitating clouds, sampled during the onset of the Indian monsoon, contain harmful metals like cadmium (Cd), copper (Cu), chromium (Cr), and zinc (Zn).

The presence of such metals not only shatters the myth of pure mountain rainwater but also raises red flags about long-term risks—especially those related to carcinogenic and non-carcinogenic diseases. Read more: 5 hill stations in India to experience scenic cable car rides The research, led by Dr. Sanat Kumar Das, Associate Professor at the Bose Institute, quantified the human health risks associated with these pollutants using detailed statistical modelling. The study found that clouds over the Eastern Himalayas were particularly toxic, with 1.5 times higher pollution levels than their southern counterparts. This elevated toxicity was attributed to a 40–60% increase in heavy metal loading, primarily from vehicular and industrial emissions in the foothill regions. Crucially, the study identifies inhalation as the most potent route of exposure, particularly in the Eastern Himalayas. The presence of dissolved chromium in clouds was linked to increased risks of carcinogenic diseases, while non-carcinogenic effects were attributed to metals like cadmium, copper, and zinc. Children, the study found, are especially vulnerable—30% more at risk than adults—due to their higher sensitivity to airborne pollutants. Health threats come not just from breathing in these toxic clouds, but also through dermal contact and ingestion, especially in high-altitude regions where cloud moisture is often harvested or consumed as water.

It notes that Indian clouds remain relatively less polluted when compared to nations like China, Italy, and the USA, placing India in a safer health zone, for now. Still, the warning is clear. What once floated above as a symbol of purity is now a vessel of pollutants. The clouds may look the same, but what they carry could be putting both human health and fragile ecosystems at serious risk.
