From zero to chandrayaan: decoding India's scientific heritage for UPSC cse

Introduction: A Celestial Echo of an Ancient Past

On August 23, 2023, as the Vikram lander of the Chandrayaan-3 mission executed a flawless soft landing on the lunar south pole, India did not just make history; it rekindled a legacy. This monumental achievement, a testament to modern India’s scientific and technological might, is deeply rooted in a rich civilizational heritage of inquiry and innovation. From the astronomical genius of Aryabhata, who conceptualized a heliocentric model centuries before Copernicus, to the surgical precision of Sushruta, India’s journey has been one of scientific curiosity. This article delves into this profound legacy, connecting the dots between ancient wisdom and the ambitious policy frameworks like the Anusandhan National Research Foundation (NRF) Act, 2023, that are shaping India’s S&T landscape today.

The Bedrock of Indian Innovation: A Glimpse into History

Ancient India was a crucible of pioneering ideas that shaped global knowledge systems. The contributions were not isolated sparks of brilliance but part of a sophisticated intellectual tradition.

Analogy: The concept of ‘Shunya’ (Zero), first formalized by Brahmagupta in the 7th century, was more than a mathematical tool. It was a philosophical masterpiece, representing the void (‘nirvana’ in Buddhism). Its role as a placeholder is the very foundation of the binary system that drives modern computing, much like a single foundational block supporting a massive digital skyscraper.

Here’s a snapshot of the key contributions from ancient Indian pioneers:

The Modern Renaissance: Architecting a Tech-Driven Future

Building on this historical foundation, modern India is making a concerted policy push to transition from a service-based economy to a knowledge-based, innovation-led global power. The last 18-24 months have been pivotal, witnessing the rollout of transformative legislation and missions.

The Anusandhan National Research Foundation (NRF) Act, 2023

Passed in August 2023, the Anusandhan National Research Foundation (NRF) Act is arguably the most significant reform in India’s R&D ecosystem. It repeals the SERB Act of 2008 and establishes the NRF as an apex body to provide high-level strategic direction to scientific research.

• Mandate: To seed, grow, and promote R&D and foster a culture of innovation across universities, colleges, and research institutions, including in the humanities and social sciences.
• Funding: It has a planned outlay of ₹50,000 crore over five years (2023-28), with a significant portion expected from the private sector, aiming to reverse India’s traditionally low Gross Expenditure on R&D (GERD).
• Governance: The Prime Minister heads the Governing Board, ensuring high-level oversight and commitment.

National Quantum Mission (NQM)

Approved in April 2023 with a budget of over ₹6,000 crore, the National Quantum Mission (NQM) aims to position India as a global leader in Quantum Technology. The mission focuses on developing quantum computers, secure quantum communication, and high-precision quantum sensors. A major breakthrough was announced in November 2025 with the development of India’s first indigenous Quantum Diamond Microscope (QDM) by a team at IIT Bombay, a device with vast applications in semiconductor analysis and neuroscience.

Fun Fact: The Iron Pillar in Delhi, over 1600 years old, has withstood corrosion due to a thin protective film of ‘misawite’—a compound of iron, oxygen, and hydrogen—that formed on its surface. This is a testament to the advanced understanding of metallurgy in ancient India.

The IndiaAI Mission

In a landmark move in March 2024, the Union Cabinet approved the IndiaAI Mission with an outlay of ₹10,371.92 crore for five years. This mission is designed to build a robust AI ecosystem through a public-private partnership model. Key components include:

• AI Compute Infrastructure: Establishing a capacity of over 10,000 Graphics Processing Units (GPUs).
• Startup Financing: Providing streamlined access to funding for deep-tech AI startups.
• Indigenous Models: Developing indigenous Large Multimodal Models (LMMs) and domain-specific foundational models.

Policy Push for Deep Tech and Traditional Medicine

• Draft National Deep Tech Startup Policy (NDTSP): Released for public consultation in 2023, this policy aims to create a supportive ecosystem for startups working on fundamental scientific challenges in areas like semiconductors, space tech, and AI.
• WHO Global Centre for Traditional Medicine: The establishment of this global hub in Jamnagar, Gujarat, in 2022 with a USD 250 million investment from India, signals the world’s growing recognition of the value of traditional knowledge systems like Ayurveda when integrated with modern science.

Statistic: India has consistently improved its ranking in the Global Innovation Index (GII), securing the 39th position among 133 economies in 2024, a remarkable leap from 81st in 2015.

Critical Policy Appraisal

The Ancient Wisdom of Ayurveda

The Charaka Samhita details eight components of Ayurveda, known as Ashtanga Ayurveda.

1. Kaya Chikitsa (General Medicine)
2. Kaumara-Bhrtya (Paediatrics)
3. Shalya Chikitsa (Surgery)
4. Salakya Tantra (Ophthalmology/ENT)
5. Buta Vidya (Demonology/Psychiatry)
6. Agada Tantra (Toxicology)
7. Rasayana Tantra (Elixirs/Rejuvenation)
8. Vajikarana Tantra (Aphrodisiacs)

Mnemonic (for Ashtanga Ayurveda): Some Surgeons Know Basic Ayurveda, Really Valuable Knowledge. (Shalya, Salakya, Kaya, Buta, Agada, Rasayana, Vajikarana, Kaumara-Bhrtya)

Analytical Lens: UPSC Focus (Mains & Prelims)

• Conceptual Basis: The Anusandhan National Research Foundation (NRF) Act, 2023 is the primary legislative framework driving the current transformation of India’s R&D sector. It operationalizes the vision set out in the National Education Policy (NEP), 2020, to create a more holistic and integrated research environment.

• UPSC Integration: Connecting the Dots

  • GS Paper 2 (Polity & Governance): The NRF represents a significant governance reform, moving from fragmented funding bodies like SERB to a centralized, high-level foundation chaired by the PM. This links to topics of policy-making, institutional frameworks, and cooperative federalism (as it aims to fund state universities).
  • GS Paper 3 (Economy & S&T): This topic is central to GS-3. It directly relates to government budgeting for R&D, the role of S&T in economic growth, the startup ecosystem (Startup India), intellectual property rights, and infrastructure development in emerging technologies like AI and Quantum Computing.
  • GS Paper 2 (International Relations): The push in deep tech and space exploration enhances India’s strategic autonomy and soft power. Initiatives like the WHO centre in Jamnagar and leadership in the Global Innovation Index are key aspects of technology diplomacy.

• Future Impact & Policy Relevance: The current policy thrust aims to create a self-reliant (Atmanirbhar) and globally competitive India. The focus on deep tech is crucial for national security, economic resilience, and addressing societal challenges in health, agriculture, and climate change. Success hinges on effective implementation, sustained funding, and fostering a culture that encourages risk-taking and innovation from the grassroots up.

• Practice Question (Prelims):

  Which ancient Indian text, authored by Sushruta, is primarily considered a foundational treatise on surgery and describes complex procedures like rhinoplasty? (a) Charaka Samhita (b) Aryabhatiya (c) Sushruta Samhita (d) Sulvasutra

  Explanation: The correct answer is (c). The Sushruta Samhita is one of the foundational texts of Ayurveda, alongside the Charaka Samhita. While Charaka Samhita deals primarily with internal medicine, Sushruta Samhita is renowned for its detailed descriptions of surgical procedures.

• Practice Question (Mains):

  The Anusandhan National Research Foundation (NRF) Act, 2023, marks a paradigm shift in India’s R&D landscape. Critically analyze its potential to bridge the gap between India’s ancient scientific legacy and its ambition to become a global innovation hub. (15 marks, 250 words)
