    • Recently, researchers detected evidence of volcanic eruption on Venus’ surface using data from NASA’s Magellan mission provided by NASA’s Jet Propulsion Laboratory.
    Planet Venus

    Earth’s Twin: Venus is Earth’s closest planetary neighbour which is similar in structure but slightly smaller than Earth.
    a. It is the second planet from the sun.
    Thick & Toxic Atmosphere: Venus has an atmosphere 50 times denser than Earth.
    a. It is wrapped in a thick, toxic atmosphere filled with carbon dioxide that traps in heat.
    Inhabitable:  Venus is the hottest planet in the solar system. The temperature of Venus is too high (about 471°C), and its atmosphere is highly acidic.
    Other Features: It has no moons and no rings.
    a. Venus’ solid surface is a volcanic landscape covered with extensive plains featuring high volcanic mountains and vast ridges.
    b. It spins from east to west, the opposite direction from all other planets in our solar system but the same as Uranus.
    • The Magellan Mission of NASA, launched in 1989, provided crucial insights into Venus’ geology. The spacecraft used Synthetic Aperture Radar to map 98% of Venus’ surface between 1990 and 1992 that revealed features that hinted at a tumultuous volcanic past.
    • Sif Mons: A volcano approximately 200 miles (300 km) wide located in the Eistla Regio region. It exhibited signs of eruption during the early 1990s.
      • Radar images show a lava flow covering about 12 square miles (30 square km) of rock.
      • It changed the perception that Venus is a dormant world.
    • Niobe Planitia: A large volcanic plain where approximately 17 square miles (45 square kilometres) of rock were produced by lava flow.
    • A 2023 study revealed that a volcanic vent on Maat Mons in a region called Atla Regio expanded and changed shape during the Magellan mission.
    • Maat Mons: In 2023, Magellan’s Radar images captured changes near the volcano Maat Mons.
      • These changes indicated a recent eruption, providing direct geological evidence of volcanic activity on Venus.
      • The outflow of molten rock filled the vent’s crater and spilled down its slopes.
    • Venus’ Evolution: The discovery of recent volcanism suggests that Venus may be more volcanically active than previously thought.
      • Understanding its volcanic history helps explain why Venus took a different evolutionary path than Earth.
    • Climate Alterations: Massive volcanic outpourings in Venus’ ancient past likely altered its climate.
      • Venus boasts scorching surface temperatures and a thick atmosphere that may have originated from intense volcanic activity.

    – It is a vent or fissure in Earth’s crust through which lava, ash, rocks, and gases erupt. It can be active, dormant or extinct.
    – An eruption takes place when magma (a thick flowing substance), formed when the earth’s mantle melts, rises to the surface. 
    – The magma is lighter than solid rock, it is able to rise through vents and fissures on the surface of the earth.
    a. After it has erupted, it is called lava.
    – Not all volcanic eruptions are explosive since explosivity depends on the composition of the magma.

    Types and Characteristics

    Cinder Cones: These are small, steep-sided volcanoes formed by the accumulation of volcanic fragments around a single vent.
    a. Eruption Style: They erupt mostly small pieces of scoria and pyroclastics.
    b. Example: Capulin Volcano in New Mexico.

    Composite Volcanoes (Stratovolcanoes): These are tall and steep with layers of lava, ash, and rock debris. They often have a conical shape.
    a. Eruption Style: High-viscosity lava, ash, and rock debris.
    b. Examples: Mount Rainier in Washington, Mount Fuji in Japan.

    Shield Volcanoes: These have gentle slopes and are shaped like a bowl or shield. They result from basaltic lava flows.
    a. Eruption Style: Low-viscosity lava that can flow great distances from the vent.
    b. Examples: Mauna Loa in Hawai’i, Iceland’s volcanic chain.

    Lava Domes: These form when thick, viscous lava accumulates near the volcanic vent. They have steep sides.
    a. Eruption Style: Slow eruptions of highly viscous lava.
    b. Example: Novarupta dome in Alaska.

    Syllabus: GS2/Health

    • Health Insurance seems to become the main component of Universal Health Coverage (UHC) discussion in the Indian Health Policy.
    • Recently, a notable health-care chain in South India announced its foray into comprehensive health insurance by combining insurance and health-care provision functions under one roof — what can be called the Indian iteration of a managed care organisation (MCO). 
    • It is timely to reflect on whether MCOs hold promise for the bigger Indian health-care landscape, particularly when it comes to extending universal health care.
    • On the health security front, for the unorganised sector, there is the Ayushman Bharat Scheme of the central government with over 490 million beneficiaries.
    • In the organized sector, the Central government runs the Employees State Insurance Corporation (ESIC) and Central Government Health Scheme (CGHS) catering to 130 million and four million beneficiaries, respectively.
    • Health insurance schemes run by various State governments cover about 200 million people.
    • Despite these large-scale provisions, about 400 million Indians are not covered under any kind of health insurance.
    • In India, ever since the first public commercial health insurance was promulgated in the 1980s, the focus has been on indemnity insurance and covering hospitalisation costs, despite a near $26 billion market for outpatient consultations in the country.
    • A Managed Care Organization (MCO) is a health plan or health care company that utilizes managed care as its model to keep the quality of care high while limiting costs.
      • The term “managed care” is used to describe a type of health care focused on helping to reduce costs, while keeping quality of care high.
    • The strongest impetus for mainstreaming MCOs in U.S. health care came in the 1970s, when cost containment concerns in health care loomed large. 
    • Cost Control: MCOs are designed to control healthcare costs by managing utilization, negotiating discounted rates with healthcare providers, and implementing cost-effective treatment protocols.
      • By coordinating care and focusing on preventive measures, MCOs aim to reduce unnecessary medical expenses.
    • Quality Improvement: MCOs often emphasize quality improvement initiatives, such as implementing clinical guidelines, monitoring outcomes, and promoting evidence-based practices.
      • This focus on quality helps ensure that patients receive appropriate and effective care.
    • Care Coordination: One of the primary roles of MCOs is to coordinate care across different providers and settings.
      • They facilitate communication among healthcare professionals, streamline referrals, and help ensure that patients receive seamless and integrated care.
    • Healthcare Access: MCOs can improve access to healthcare services by offering networks of providers and facilities, including primary care physicians, specialists, hospitals, and other healthcare professionals.
      • This network approach helps patients access a wide range of services within their insurance coverage.
    • Risk Management: MCOs assume financial risk for the healthcare services they provide, which incentivizes them to manage costs and outcomes effectively.
      • Through risk-sharing arrangements with providers and innovative payment models, MCOs align financial incentives with quality and efficiency goals.

    • Securities and Exchange Board of India has notified a framework for issuance of subordinate units by privately placed infrastructure investment trusts (InvITs).


    • The issuance of subordinate units is primarily intended to bridge the valuation gaps that may arise as a result of the difference in the valuation of an asset assessed by the Sponsor (in its capacity of the asset seller) and the InvIT (in capacity of the asset buyer).
    • Also, the framework has been designed to include risk mitigation measures in respect of such units.
    • An Infrastructure Investment Trust (InvIT) is like a mutual fund, which enables direct investment of money from individual and institutional investors in infrastructure projects to earn a portion of the income as return.
      • InvITs work similarly to Real Estate Investment Trusts (REITs), but instead of investing in real estate properties, they invest in infrastructure projects like roads, power plants, pipelines, and other such assets.
    • InvITs serve as an avenue for investors to participate in the infrastructure development of the country while also generating returns on their investments.
    • InvIT are regulated by the SEBI (Infrastructure Investment Trusts) Regulations, 2014.
