“We Could’ve Done It in 3 Years”: Nambi Narayanan Slams Funding Delays in India’s Space Tech Journey

At a time when India’s space startup ecosystem is surging, one of its foundational voices has issued a sobering reminder: progress could have come decades earlier, if only the money had followed the vision.

Narayanan emphasized that while India has made strides in rocket technology, financial bottlenecks remain a major hurdle for faster adoption of cutting-edge space systems.

Speaking at National Innovation Day at Rajalakshmi Engineering College, Padma Bhushan awardee and former ISRO scientist Nambi Narayanan reflected on the long, winding road of India’s space propulsion development. His message was clear: funding bottlenecks—not technical limitations—were the real drag force.

Nambi Narayanan

We could have completed the liquid propulsion system in three years, Narayanan said. But it took nearly 20 years. Why? Because the funds were not available when we needed them.

The Cost of Delay

• Narayanan’s remarks cut to the heart of a recurring theme in India’s tech evolution: brilliant minds hamstrung by budgetary hesitation.
• The liquid propulsion system—critical for modern satellite launches and interplanetary missions—was ready to leap forward in the 1990s.
• Instead of a sprint, it became a marathon.

We had the technology. We had the talent. What we lacked was timely investment, he added.

A New Era, But Old Lessons

• India’s space sector has since opened its doors to private players, with over 300 startups now active.
• The market is projected to reach $44 billion by 2033.
• Yet Narayanan’s warning resonates: innovation without funding is just aspiration.

Editorial Takeaway

• Narayanan’s voice is more than nostalgic—it’s strategic.
• As India positions itself as a global space power, his message is a call to fund not just the future, but the present.
• Because in space, delays aren’t just costly—they’re orbital.

Starscapes and Gujarat Tourism Join Forces to Build India’s 1st Dark-Sky Astro Villages

• Starscapes to conduct a detailed study to identify potential stargazing locations across the state

Starscapes, India’s leading astro-tourism company, has signed a Memorandum of Understanding with Gujarat Tourism to jointly develop Gujarat as a key astro-tourism destination over the next five years.

As a part of the collaboration, Starscapes will conduct a detailed study to identify potential stargazing locations across the state, starting with North Gujarat. The selected sites will be evaluated based on light pollution levels, accessibility, and suitability for astro-tourism infrastructure. Gujarat Tourism’s approach to categorizing various types of tourism such as adventure, heritage and nature tourism provides a clear advantage in designating specific areas as dark-sky zones. This will play an important role in exclusively developing astro-tourism without interference from other tourism activities that may contribute to light pollution.

The identified astro-tourism zones will later be developed into Astro Villages, where local communities will play a key role in reducing light pollution and preserving dark skies. The initiative aims to generate employment opportunities for local communities, improve livelihood while creating sustainable astro tourism experiences.

 

Commenting on the partnership, Ramashish Ray, Founder, Starscapes, said, “ "From the vast salt deserts of Kutch to the clear skies around Gir National Park, Gujarat offers some of the most pristine and untouched dark-sky locations with immense potential for astro-tourism. Our goal is to work closely with the local communities, empowering them to become ambassadors of dark skies and to create a model of responsible, sustainable tourism. We’re excited to partner with Gujarat Tourism to develop the state into a leading astro-tourism destination."

This initiative builds on Starscapes’ ongoing efforts to promote astro-tourism across India.

IIT Mandi’s Quantum-Inspired Theory Reveals Hidden Logic Behind Collective Movement

• IIT Mandi researchers uncover how quantum-inspired dynamics in visual perception can explain flocking, swarming, and coordination, opening doors to new advances in robotics and neuroscience

Why do birds flock, fish school, or humans synchronize their movements without a designated leader? This age-old question has fascinated scientists across disciplines for decades. Now, 0 at the Indian Institute of Technology (IIT) Mandi have put forward a groundbreaking explanation: the secret may lie in quantum-inspired perception.

The study, led by Prof. Laxmidhar Behera and his team, Dr. Jyotiranjan Beuria and Mayank Chaurasiya, recently published in the prestigious journal Proceedings of the Royal Society A (2025), introduces a radical mathematical framework to explain how coordination emerges in nature. In classical models of collective motion, such as the well-known Vicsek model, agents align their movement based on their neighbors’ directions. While these models capture some aspects of swarming and flocking, they often fall short in accounting for real-world complexities, such as noisy environments, delays in response, or ambiguous information. The IIT Mandi team approached the puzzle from a different angle. Drawing inspiration from quantum mechanics, they proposed that each agent’s perception does not collapse immediately into a definite decision. Instead, it exists in a superposition of possibilities, much like a particle in quantum physics can exist in multiple states until observed.

Commenting on the study, Prof. Laxmidhar Behera, Director of IIT Mandi and co-author of the paper, said –

“Our work shows that quantum-inspired ideas can move beyond physics and provide fresh insight into one of nature’s oldest mysteries: how collective order arises out of local perception. The implications range from understanding the mind and brain to engineering next-generation intelligent systems.”

His words reflect a growing trend in modern science: borrowing principles from quantum theory to enrich disciplines far beyond fundamental physics. By bridging cognitive science, biology, and engineering, the IIT Mandi study points to a unifying framework for perception and coordination.

A Unified Framework for Nature and MachinesIn this framework, agents perceive their neighbors not through fixed snapshots but through entangled perceptual states that evolve dynamically. Coordination arises naturally as these states resolve, balancing uncertainty and alignment in a way that mirrors quantum behavior. A central contribution of the study is the introduction of two novel quantities: perception strength, which measures how strongly agents align their perceptual states, and perceptual energy, which measures the stability of collective perception within the group. Together, these measures allow scientists to quantify how coordination emerges even in noisy or incomplete conditions. Importantly, the researchers demonstrated that classical flocking models are special cases of their broader, quantum-inspired theory. This means that existing frameworks for collective motion can be seen as approximations within a more general, perception-driven model.

New Metrics for Measuring Group Intelligence

The implications of this work extend far beyond theory. In biology, the framework offers a new perspective on how swarms of animals remain cohesive despite disturbances. Instead of relying solely on physical interaction rules, the study suggests that perception itself plays a fundamental role in generating order in living systems.

Game-Changing Implications

In robotics, swarm robotics such as coordinated drones used in search-and-rescue operations, environmental monitoring, or planetary exploration could adopt quantum-inspired perception to achieve more flexible and adaptive coordination. In neuroscience and psychology, the study resonates with how human perception often involves ambiguity, sudden switching, and context-dependent interpretation. By offering a rigorous mathematical model for perceptual dynamics, the framework provides a fresh way to understand brain function and cognitive processes. In artificial intelligence, future AI systems could harness quantum-inspired perceptual operators to handle uncertainty with greater robustness, avoiding brittle or premature decisions when confronted with ambiguous or incomplete data.

Truth in the Time of Toxins: What 'Bad Science' Warns Us About

In a world where a celebrity’s juice cleanse gets more airtime than a peer-reviewed study, Bad Science by Ben Goldacre is both sword and shield. With biting humor and analytical rigor, Goldacre aims not just to entertain—but to arm the public against misinformation dressed in lab coats.

Deconstructing Hype: The Core Messages of Bad Science

When its apparently an age where clickbait cures and “breakthroughs" are endorsed by celebrities, the book Bad Science by Ben Goldacre slashes through the noise. It reveals how science can be twisted—or ignored—to sell ideas, products, and agendas.

The book, originally published in the UK in 2008, primarily focuses on examples from the UK and Western media, especially in the context of health journalism, education, and pharmaceutical practices. However, it does touch on global implications of pseudoscience and misinformation—including how misleading health claims can affect developing countries, particularly in Africa and Asia.

Pseudoscience Wears a Lab Coat

Goldacre shows that “science-sounding” jargon and anecdote can mask empty claims. He exposes:

• Homeopathy’s absurd dilutions presented as potent medicine
• Brain Gym exercises billed as neurological cures
• Detox footpads and ear candles marketed with pseudo-anatomical mumbo-jumbo

These examples illustrate how easy it is to dress nonsense in scientific language—and how few people question the rules of biology it violates.

The Media’s Amplification Machine

Headlines trade nuance for drama, and The common men pays the price. Goldacre dissects:

• Sensational reporting of preliminary or weak studies
• Inflated links between vaccines and autism during the MMR scare
• Misuse of relative risk to make tiny effects look earth-shattering

By following the press’s temptation to oversimplify, he warns us that every catchy headline may hide half-truths.

When Money Drives the Data

Scientific research isn’t immune to commercial pressures. Bad Science uncovers tactics like:

• Cherry-picking favourable trial results and burying the rest
• Presenting relative risk (e.g., “50% reduction”) without absolute figures
• Ghost-writing academic papers on behalf of pharmaceutical sponsors

Goldacre argues for open data, transparent methodologies, and independent scrutiny so that medicine serves health and not marketing.

The Curious Power of Placebos

Placebos aren’t “just sugar pills”—they reveal how expectation shapes outcomes. Goldacre highlights studies where:

Pink pills boosted concentration more than blue ones

• Higher pill counts (even inert) led to stronger symptom relief
• A doctor’s empathy and confidence significantly altered patient responses

Understanding placebo effects reminds us that context, belief, and presentation matter in every clinical encounter.

A Call to Critical Thinking

Bad Science isn’t about making everyone a lab-coat expert overnight. It’s a manifesto for:

• Asking pointed questions when faced with bold claims
• Reading beyond headlines and checking sample sizes, controls, and reporting standards
• Demanding transparency from researchers, media, and corporations

By arming ourselves with skepticism and curiosity, we become smarter consumers of information—and better guardians of our own health.

Bad Science also touch on the pharmaceutical industry but more as a warning signal than a deep dive. Goldacre critiques how drug companies can distort evidence, manipulate trial results, and influence public perception through selective data and marketing tactics.

• Clinical Trials and Data Manipulation: Pharmaceutical companies sometimes design trials to favor their products—using small sample sizes, biased endpoints, or excluding negative results. Goldacre highlights how publication bias creates a skewed picture of a drug’s effectiveness.
• Relative Risk vs. Absolute Risk: Companies use relative risk to make benefits sound bigger than they are. A “50% reduction” might only mean going from 2 in 1,000 to 1 in 1,000—not a miracle, just misleading framing.
• Ghostwriting and Sponsored Research: Some academic papers are secretly written by pharma staff and published under independent researchers' names. Goldacre critiques the blurry line between science and sales.

The Bad Science author, Goldacre, also wrote Bad Pharma, an entire exposé of the industry. It covers:

• Regulators and journals enabling bad practices
• The global consequences of hidden data
• Reforms needed to fix systemic issues

Whether you’re a student, journalist, or simply a skeptical reader, Bad Science equips you to spot red flags, decode data, and insist on evidence that truly matters.

Self-Assembling Materials: Programmable Matter That Builds Itself

I've watched materials science evolve for two decades, but self-assembling materials still feel like something from science fiction. These substances can automatically arrange themselves into predetermined shapes when triggered — no external assembly required. The concept challenges our basic assumptions about manufacturing and construction. Think about how algorithms drive predictable outcomes in digital environments, like the sophisticated random number generators that power platforms such as 1xbet online casino free games. Self-assembling materials work on similar principles, but with physical atoms instead of digital code.

Current Research and Laboratory Breakthroughs

The latest developments in programmable matter research show promising but uneven progress. Self-assembling materials research reveals significant advances at MIT, Harvard, and several international research centers.

Key areas where researchers are making headway include:

• DNA-based assembly systems that create predetermined structures at the molecular level
• Shape-memory alloys that transform into specific configurations when heated
• Magnetic particle systems that organize into complex three-dimensional structures
• Polymer networks that respond to pH changes or electrical stimulation
• Protein-based materials that fold into functional shapes when exposed to specific chemicals

Current laboratory demonstrations remain limited in scale and complexity. MIT's recent work with DNA origami can create structures measuring just a few hundred nanometers. The precision is remarkable, but scaling up presents significant challenges. Shape-memory alloys work at larger scales but typically only perform simple transformations — bending, twisting, or expanding.

Research teams face a fundamental challenge: maintaining precision as complexity increases. Simple structures self-assemble reliably, but adding more components introduces exponentially more failure points. The mathematics governing these systems become unwieldy quickly.

Temperature control proves critical for most self-assembling systems. Small temperature variations can derail the entire assembly process. This sensitivity limits practical applications in uncontrolled environments.

Engineering Applications and Manufacturing Potential

The manufacturing implications could reshape how we build everything from electronics to buildings. Self-assembling manufacturing applications show early adoption in specialized fields.

Aerospace engineers are testing self-assembling components for spacecraft that can repair themselves during long missions. The components remain dormant during launch, then activate when needed. This approach could reduce mission costs significantly by eliminating the need for redundant backup systems.

Medical applications show particular promise. Self-assembling drug delivery systems can target specific cells, then release their payload when they encounter the right chemical signals. Early trials suggest this approach could reduce side effects while improving treatment effectiveness.

Construction materials that adapt to environmental conditions represent another frontier. Concrete that self-heals when cracked, or building materials that adjust their thermal properties based on weather conditions. These aren't theoretical anymore — small-scale prototypes exist.

The electronics industry is experimenting with self-assembling circuits. Components could organize themselves during manufacturing, potentially reducing defect rates and production costs. Samsung and Intel have invested in research programs, though commercial applications remain years away.

Limitations and Technical Hurdles

Let's be realistic about the current state of this technology. Self-assembling materials work well in controlled laboratory conditions, but real-world environments present numerous challenges.

Contamination derails most self-assembly processes. A single foreign particle can prevent proper assembly or cause the structure to form incorrectly. Clean room manufacturing might solve this problem, but it limits where these materials can be used.

Energy requirements remain substantial for most systems. Many self-assembling materials need external energy sources — heat, electricity, or chemical fuel — to trigger assembly. This dependency limits autonomous applications.

Timing coordination becomes complex when multiple components must assemble simultaneously. Getting everything to happen in the right sequence, at the right speed, requires precise control systems. Current approaches work for simple structures but struggle with complex assemblies.

Material compatibility issues restrict design options. Not all substances can be programmed to self-assemble, and those that can often require specific environmental conditions that conflict with other materials in the same system.

Quality control presents unique challenges. Traditional manufacturing allows inspection at multiple stages, but self-assembling systems often work as black boxes. You trigger the process and hope everything works correctly.

Cost remains prohibitive for most applications. Programmable materials require expensive precursor chemicals and sophisticated control systems. Mass production might reduce costs, but we're nowhere near that scale yet.

The field progresses steadily, but predictions about widespread adoption keep getting pushed back. What seemed possible in five years now looks more like ten or fifteen years away. That's not pessimism — it's the reality of translating laboratory successes into practical applications.

Nevertheless, the potential applications justify continued research investment. Self-assembling materials could solve manufacturing problems we haven't figured out any other way.

India to Launch Ultra-Precise Timekeeping System with ISRO & NPL

In a major leap toward technological self-reliance, India is set to roll out a nationwide precision timekeeping system, developed in collaboration with the Indian Space Research Organisation (ISRO) and the National Physical Laboratory (NPL), reported news agency PTI. The initiative aims to deliver nanosecond-level synchronization across critical sectors, from telecom and transport to defense and energy.

A Strategic Partnership for National Precision

The project, announced during the 89th International Electrotechnical Commission (IEC) General Meeting in New Delhi, will establish five regional hubs to disseminate Indian Standard Time (IST) with unprecedented accuracy.

• ISRO will provide satellite infrastructure and signal transmission.
• NPL, India’s official timekeeper, will anchor the system using atomic clocks and calibration protocols.
• The Ministry of Consumer Affairs is overseeing implementation, aligning it with India’s legal metrology and digital infrastructure goals.

Why It Matters

This precision timing backbone is expected to revolutionize:

• Smart grids and energy distribution
• Automated transport and logistics
• High-frequency financial transactions
• Cybersecurity and data integrity
• Telecom and 5G rollout

India’s emergence as the second-largest mobile phone manufacturer and its growing footprint in EVs, solar tech, and AI-driven automation make synchronized timing essential for global competitiveness.

Global Standards, Local Impact

India will join a select group of nations—like the US, Germany, and Japan—with multi-site time dissemination networks. The system also supports India’s recent milestone as the 13th country authorized to issue OIML pattern approvals, strengthening its role in international legal metrology.

Enabling National Missions

The timekeeping system complements flagship initiatives such as:

• FAME India (electric mobility)
• PM-KUSUM (solar-powered agriculture)
• National Green Hydrogen Mission

Together, these efforts signal India’s intent to lead in climate resilience, digital infrastructure, and scientific innovation.

Blood Moon 2025: Science, Spectacle & Spiritual Shifts

On the night of September 7–8, 2025, the skies over India and much of the Eastern Hemisphere were set ablaze by one of the most mesmerizing celestial events of the year—a Blood Moon, also known as a total lunar eclipse. For 82 minutes, the Moon bathed in a deep crimson glow, captivating skywatchers and stirring ancient myths and modern reflections alike.

The Science Behind the Scarlet Glow

• Earth aligns perfectly between the Sun and Moon, casting its shadow across the lunar surface.
• Sunlight filters through Earth’s atmosphere, scattering shorter blue wavelengths and allowing longer red wavelengths to bend toward the Moon.
• The result: a coppery-red Moon, visible to the naked eye and safe to observe without any special equipment.

This year’s eclipse was especially notable because:

• It lasted 82 minutes, making it one of the longest total lunar eclipses since 2022.
• It was visible across India, Asia, Africa, Europe, and Australia, reaching nearly 85% of the global population.
• The Moon was near apogee (its farthest point from Earth), which slowed its transit and extended the eclipse duration.

Cultural Echoes & Ancient Lore

• In Incan mythology, a jaguar was believed to devour the Moon.
• In Hindu tradition, the demon Rahu swallows the Moon, causing eclipses.
• Ancient Greeks saw the Moon goddess Selene veiled in darkness, prompting rituals to ward off ill omens.

Today, while science explains the phenomenon, the spiritual symbolism remains potent.

Astrological Insights: Pisces & Aquarius Energy Collide

This year’s Blood Moon occurred at 15° Pisces, opposing the Sun in Virgo—a cosmic tug-of-war between dreams and practicality. Astrologers interpret this eclipse as a powerful emotional reset, urging us to:

• Release illusions and outdated beliefs.
• Heal emotional wounds and embrace transformation.
• Step into new chapters with clarity and courage.

Zodiac Highlights

Zodiac Sign	Astrological Impact
Aries	Let go of impulsiveness; embrace patience and long-term vision.
Leo	Relationships mirror your ego—seek balance and humility.
Pisces	Expect deep emotional revelations and spiritual growth.
Virgo	Your routines may shift—prioritize health and inner harmony.

How to Experience It

• No gear needed—just clear skies and curiosity.
• Best viewed from rooftops, open fields, or hilltops.
• Binoculars enhance the view, revealing lunar textures and color gradients.

Whether you're a scientist, a stargazer, or a seeker of cosmic meaning, the Blood Moon of 2025 offered more than just a visual treat, it was a moment to pause, reflect, and realign. As the Moon glowed red, it reminded us that even in shadow, there is beauty, mystery, and transformation.

India Expands Astronaut Pool to Include Women and Civilians in Bold Space Push

In a landmark move to democratize space exploration, India will now include women and professionals from diverse backgrounds in its astronaut pool, breaking away from its earlier reliance solely on Indian Air Force pilots. The announcement was made by Prime Minister Narendra Modi during his address on National Space Day, marking a new chapter in the country’s human spaceflight ambitions.

Prime Minister Modi addressed the country on the National Space Day, August 23, 2025. He announced plans to form a diverse astronaut pool and emphasized the need for 40–50 trained astronauts to support future missions like Gaganyaan, the Bharatiya Antariksh Station, and a manned Moon mission.

From Air Force to All Walks of Life

Until now, India’s astronaut training was limited to elite Air Force personnel. The first batch for the Gaganyaan mission—Group Captains Shubhanshu Shukla, Prashanth Nair, Angad Pratap, and Ajith Krishnan—underwent rigorous training in Russia and India. However, ISRO officials confirmed that future selections will be open to women and civilians, reflecting global trends in space participation.

"The astronaut pool will not be restricted to the Air Force alone. It will have people from all walks of life,” said a senior ISRO official. Globally, it’s not just researchers but also entrepreneurs who are travelling to space.

Vision for Human Spaceflight

The initiative aligns with India’s long-term space roadmap:

• Gaganyaan Mission: First crewed flight expected by 2027
• Bharatiya Antariksh Station: Indigenous space station planned by 2035
• Manned Moon Mission: Targeted for 2040

PM Modi emphasized the need for a ready pool of 40–50 astronauts to support sustained missions and invited youth to join this national endeavor.

A New Era of Inclusivity

The decision to diversify the astronaut pool is seen as a major step toward inclusivity and innovation in India’s space program. It also fulfills a promise made by Modi in his 2018 Independence Day speech: “An Indian boy or girl will unfurl the Tricolour in space."

In my conversation with Group Captain Shubhanshu, I saw the boundless courage and infinite dreams of the youth of New Bharat. On this Space Day, I invite my young friends to join this astronaut pool and give wings to the dreams of Bharat. – PM Modi. 

Global Context

India joins a growing list of nations expanding astronaut eligibility beyond military ranks. NASA, ESA, and private companies like SpaceX have already sent scientists, engineers, and even artists into orbit.

Time Reversal: Scientists Achieves A Real-Life Sci-Fi Breakthrough

Austrian scientists have pulled off something that sounds straight out of science fiction: they’ve successfully reversed time for a single photon using a device called a quantum switch. This isn’t about building a time machine to visit the dinosaurs—it’s about manipulating the flow of time within quantum systems, where the rules of reality bend in mind-boggling ways.

What They Did

• Researchers from the Austrian Academy of Sciences (ÖAW) and the University of Vienna used a photon (a particle of light) and sent it through a crystal.
• With the help of the quantum switch, they were able to rewind the photon’s state—returning it to how it was before the journey began.
• This process, called a rewind protocol, works even without knowing what happened to the particle during its journey—a feat previously thought impossible in quantum mechanics.

Fast-Forwarding Time Too

• The team didn’t stop at rewinding. They also discovered how to accelerate time for a quantum system.
• By redistributing “evolutionary time” among identical systems, they made one system age 10 years in just one, while the others remained unchanged.

Why It Matters

• While reversing time for humans is far beyond reach (it would take millions of years to rewind even one second of a person’s life), this discovery could revolutionize quantum computing.
• It opens the door to undoing errors in quantum processors, making them more powerful and reliable.

A New Way to Watch Reality

Physicist Miguel Navascués likened classical physics to watching a movie in a theater—linear and unchangeable. Quantum physics, he said, is like watching at home with a remote: you can rewind, fast-forward, or skip scenes.
