  • Odisha start-up flight-tests an autonomous in-space pharmaceutical manufacturing payload

    Why in the News

    A Bhubaneswar-based start-up, Serendipity Space, has flight-tested a prototype satellite carrying Alchemy, an autonomous pharmaceutical manufacturing payload, using a high-altitude balloon at the TIFR facility in Hyderabad. The technology aims to manufacture pharmaceutical products in microgravity without human supervision.

    How does it work?

    1. Microgravity: Near-weightlessness reduces sedimentation, buoyancy and convection.
    2. Crystal growth: Crystals can form differently and potentially with greater uniformity than on Earth.
    3. Autonomous processing: The satellite carries reagents and hardware and executes the manufacturing sequence independently.
    4. Recovery: Processed material is returned to Earth using a re-entry system and heatshield.

    What is LEO?

    • Low Earth Orbit (LEO) extends roughly up to 2,000 km above Earth.
    • The proposed system is intended for an altitude of about 400 to 500 km.

    What did the balloon test demonstrate?

    • Tested the satellite prototype under near-space conditions.
    • Validated avionics, heatshield and Alchemy payload.
    • Demonstrated autonomous operation.
    • Tested controlled return to Earth.
    • Serves as a relatively low-cost step before orbital deployment.

    How is it different from earlier space-based drug research?

    • Earlier experiments on platforms such as the ISS generally required crew involvement. The distinguishing feature here is a dedicated free-flying satellite designed for autonomous pharmaceutical manufacturing.
    • International examples include Varda Space Industries, Redwire and experiments aboard China’s Tiangong station.

    Why is it important for India?

    • Promotes private-sector space innovation.
    • Expands India’s space ecosystem beyond Bengaluru to cities such as Bhubaneswar, Pune and Ahmedabad.
    • Creates opportunities in pharma, biotechnology, space engineering and advanced manufacturing.
    • Demonstrates potential convergence of space technology + biotechnology + pharmaceuticals.

  • India crosses 300 GW of non-fossil power capacity

    Why in the News

    India’s non-fossil fuel capacity has crossed 300 GW, achieving about 60% of the 500 GW target for 2030. The key challenge is converting installed capacity into actual electricity generation.

    What is the 500 GW Target?

    1. Panchamrit pledge: India committed at COP26, Glasgow (2021) to achieve 500 GW of non-fossil electricity capacity by 2030.
    2. Coverage: Includes solar, wind, hydro and nuclear capacity.
    3. Not total capacity: It excludes fossil-fuel capacity such as coal and gas.

    Why Capacity ≠ Generation?

    1. Capacity factors: Solar and wind are intermittent, so installed capacity does not translate proportionately into electricity generated.
    2. Storage gap: Batteries and pumped-storage hydropower are needed to provide reliable renewable power.
    3. Grid constraints: Transmission and grid-balancing infrastructure must expand alongside renewable capacity.
    4. Peak demand mismatch: Renewable generation may not coincide with periods of highest electricity demand.

    Value Addition

    • Panchamrit: 500 GW non-fossil capacity by 2030; 50% energy requirements from renewables; reduce projected carbon emissions by 1 billion tonnes; reduce emissions intensity by 45%; achieve net zero by 2070.
    • Key challenge: Shift from capacity addition → reliable, dispatchable clean power.

    “[2022, GS3, 15 marks] Do you think India will meet 50 percent of its energy needs from renewable energy by 2030? Justify your answer. How will the shift of subsidies from fossil fuels to renewables help achieve the above objective? Explain.”

    [2026] Consider the following statements with reference to India’s response to climate change:
    I. India’s Long-Term Low Emission Development Strategy (LT-LEDS) is a crucial tool for achieving net-zero emissions by 2070
    II. India’s 4th Biennial Update Report (BUR-4) submitted in December, 2024 recorded around 8% decrease in Greenhouse gas emissions in 2020 over 2019.
    III. Climate-resilient development necessarily depends on quick and short-term achievement of emission reduction targets.
    Which of the following relationships among the above statements is/are correct?
    1. Statement I is empirically supported by statement II.
    2. Statement III contradicts the approach implicit in statement I.
    3. Statement I and statement III together establish the premise of long-term sustainability.

  • How ‘ghost particles’ can point the way to spent nuclear fuel

    Why in the News

    Scientists have achieved the first high precision measurement of the neutrino signature from spent nuclear fuel, enabling remote monitoring of nuclear material and strengthening global nuclear non proliferation efforts.

    What is a neutrino?

    • Ghost particle: A neutrino is a nearly massless, electrically neutral subatomic particle that interacts only through the weak nuclear force and gravity.
    • Produced in nuclear reactions: They are emitted in large numbers during nuclear fission, radioactive decay, and reactions inside stars.
    • Highly penetrating: Since neutrinos rarely interact with matter, they can pass through the Earth almost unaffected, making them extremely difficult to detect.

    What did the study achieve?

    • First precise measurement: Researchers in France made the first high precision measurement of the neutrino emissions from spent nuclear fuel.
    • Remote monitoring: The neutrino signal can be measured without physically opening or handling the spent fuel.
    • Scientific validation: The findings were published in a leading peer reviewed physics journal.

    Why is this important for nuclear non proliferation?

    • Supports IAEA safeguards: Enables the International Atomic Energy Agency (IAEA) to verify spent nuclear fuel remotely.
    • Detects diversion: Changes in the neutrino signal can indicate diversion of plutonium or other fissile material for weapons.
    • Strengthens nuclear safeguards: Provides a non intrusive and tamper resistant method to improve verification of nuclear material.
    • Enhances transparency: Builds confidence in peaceful civilian nuclear programmes.

    Prelims Pointers

    • The International Atomic Energy Agency (IAEA) is the UN agency responsible for promoting peaceful uses of nuclear energy and implementing nuclear safeguards.
    • Neutrinos are electrically neutral, nearly massless particles that interact via the weak nuclear force.
    • Nuclear reactors and spent nuclear fuel continuously emit neutrinos.
    • Spent nuclear fuel contains plutonium that can potentially be separated for nuclear weapons, making its monitoring important.

    “[2020] In India, why are some nuclear reactors kept ‘IAEA Safeguards’ while others are not?
    (a) Some use uranium and others use thorium
    (b) Some use imported uranium and others use domestic supplies
    (c) Some are operated by foreign enterprises and others are operated by domestic
    (d) Some are State-owned and others are privately-owned

  • Nearly 94,000 government schools shut in a decade

    Why in the News?

    A NITI Aayog report shows that about 94,000 government schools closed over the past decade. While the government calls it school rationalisation, concerns have been raised over its impact on access to education and the Right to Education (RTE).

    Key Findings

    • Government school enrolment declined from 71% (2005) to 49.24% (2024-25).
    • The sharpest decline was seen in Uttar Pradesh, Madhya Pradesh, and Jammu & Kashmir.

    Government’s Stand vs Concerns

    • Greater impact on SC, ST, girl students and poor households.
    • May push disadvantaged families towards unaffordable private schools.

    Link with the Right to Education (RTE)

    • The Right of Children to Free and Compulsory Education (RTE) Act, 2009 guarantees a neighbourhood school for children aged 6 to 14 years.
    • School closures should not compromise this legal entitlement or equitable access.
    • Unified District Information System for Education Plus (UDISE+) is India’s official school education database.

    [2018] Consider the following statements:

    1. As per the Right to Education (RTE) Act, to be eligible for appointment as a teacher in a State, a person would be required to possess the minimum qualification laid down by the concerned State Council of Teacher Education.

    2. As per the RTE Act, for teaching primary classes, a candidate is required to pass a Teacher Eligibility Test conducted in accordance with the National Council of Teacher Education guidelines.

    3. In India, more than 90% of teacher education institutions are directly under the State Governments.

  • The IACS and the making of modern Indian science

    Why in the News?

    The Indian Association for the Cultivation of Science (IACS) marked its 150th anniversary this year. It was established on 29 July 1876 as India’s first national institution dedicated to scientific research by Indians.

    What is the Indian Association for the Cultivation of Science (IACS)?

    1. Founding: The IACS was established on 29 July 1876 in Calcutta by Mahendralal Sircar, as the country’s first institution dedicated to scientific research led by Indians.
    2. Founding vision: Sircar proposed the IACS in an 1869 article in the Calcutta Journal of Medicine, arguing that scientific education was indispensable for India’s intellectual and societal progress.
    3. Colonial context: Sircar’s founding was a direct response to what he described in 1872 as the colonial government’s failure to “afford any opportunity” or “encouragement to the pursuit of science by the native of this country.”

    How did the IACS produce Raman’s discovery of the Raman effect?

    1. Raman’s introduction to IACS: After joining the Accountant General’s Office in Calcutta in 1907, C V Raman discovered the IACS and was given open access to its laboratories by Amrit Lal Sircar, the founder’s son.
    2. Dual life as scientist and officer: For nearly a decade, Raman worked at the IACS laboratory in the early mornings and evenings while serving as a government officer during the day, continuing even after he became Palit Professor of Physics at Calcutta University in 1917.
    3. The discovery: Raman made his most celebrated discovery, the Raman effect, in the IACS laboratories, announcing it to the world on 28 February 1928.
    4. Nobel recognition: The discovery earned Raman the Nobel Prize in Physics in 1930, making him the first Asian scientist to win a Nobel Prize in the sciences.

    What does IACS’s history reveal about colonial-era Indian science?

    1. Institutional gap Sircar identified: Sircar’s founding case rested on the argument that Indians needed their own institution because the colonial state had not created one, showing that India’s earliest scientific self-reliance was born out of exclusion rather than official support.
    2. Vision fulfilled: Raman’s Nobel Prize, won through work conducted at an institution founded and funded by Indians, is presented as the fulfilment of Sircar’s original claim that such an institution could produce discoveries of international significance without depending on colonial institutional support.

    Conclusion

    The IACS’s 150-year history runs from Mahendralal Sircar’s 1876 founding, born of colonial neglect of Indian scientific talent, to C V Raman’s 1930 Nobel Prize, won through research conducted entirely within that institution. The anniversary is presented as a reminder that India’s earliest scientific self-reliance predates independence by seven decades.

    Back2Basics:

    1. National Science Day: India observes National Science Day on 28 February each year to mark the anniversary of the announcement of the Raman effect.
    2. Present role: IACS continues to function as an autonomous research institute under the Department of Science and Technology, focused on basic sciences.
