    Mars ‘Opposition’ Event

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Due to an event referred to as “opposition”, which takes place every two years and two months, Mars will shine the brightest.

    Try this question from CSP 2017:

    Q.Which region of Mars has a densely packed river deposit indicating this planet had water 3.5 billion years ago?

    (a) Aeolis Dorsa (b) Tharsis (c) Olympus Mons (d) Hellas

    What is the Opposition Event?

    • ‘Opposition’ is the event when the sun, Earth and an outer planet (Mars in this case) are lined up, with the Earth in the middle.
    • The time of opposition is the point when the outer planet is typically also at its closest distance to the Earth for a given year, and because it is close, the planet appears brighter in the sky.
    • An opposition can occur anywhere along Mars’ orbit, but when it happens when the planet is also closest to the sun, it is also particularly close to the Earth.
    • It will outshine Jupiter, becoming the third brightest object (moon and Venus are first and second, respectively) in the night sky during the month of October.

    When does opposition happen?

    • Earth and Mars orbit the sun at different distances (Mars is farther apart from the sun than Earth and therefore takes longer to complete one lap around the sun).
    • In fact, the opposition can happen only for planets that are farther away from the sun than the Earth.
    • In the case of Mars, roughly every two years, the Earth passes between sun and Mars, this is when the three are arranged in a straight line.
    • Further, as the Earth and Mars orbit the sun, there comes a point when they are on the opposite sides of it, and hence very far apart. At its farthest, Mars is about 400 million km from the Earth.
    • In case of opposition, however, Mars and Sun are on directly opposite sides of the Earth. In other words, the Earth, sun and Mars all lie in a straight line, with the Earth in the middle.

    Logic behind the name

    • As per NASA, from an individual’s perspective on the Earth, Mars rises in the east and after staying up all night, it sets in the west just as the sun rises in the east and sets in the west.
    • Because from the perspective on Earth, the sun and Mars appear to be on the opposite sides of the sky, Mars is said to be in “opposition”.
    • Essentially, the opposition is a reference to “opposing the sun” in the sky.

    National Supercomputing Mission (NSM)

    Prelims Only | Science Tech | Mains Paper 3: Achievements Of Indians In S&T

    The Centre for Development of Advanced Computing (C-DAC) has launched the second phase of the ambitious National Supercomputing Mission (NSM).

    Tap to read more about National Supercomputing Mission (NSM):

    [pib] National Supercomputing Mission (NSM)

    National Supercomputing Mission (NSM)

    • NSM is a proposed plan by GoI to create a cluster of seventy supercomputers connecting various academic and research institutions across India.
    • In April 2015 the government approved the NSM with a total outlay of Rs.4500 crore for a period of 7 years.
    • The mission was set up to provide the country with supercomputing infrastructure to meet the increased computational demands of academia, researchers, MSMEs, and startups by creating the capability design, manufacturing, of supercomputers indigenously in India.
    • Currently, there are four supercomputers from India in the Top 500 list of supercomputers in the world.

    Aims and objectives

    • The target of the mission was set to establish a network of supercomputers ranging from a few Tera Flops (TF) to Hundreds of Tera Flops (TF) and three systems with greater than or equal to 3 Peta Flops (PF) in academic and research institutions of National importance across the country by 2022.
    • This network of Supercomputers envisaging a total of 15-20 PF was approved in 2015 and was later revised to a total of 45 PF (45000 TFs), a jump of 6 times more compute power within the same cost and capable of solving large and complex computational problems.

    What is a Supercomputer?

    • A supercomputer is a computer with a high level of performance as compared to a general-purpose computer.
    • The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).
    • Since 2017, there are supercomputers which can perform over a hundred quadrillion FLOPS (petaFLOPS).
    • Since November 2017, all of the world’s fastest 500 supercomputers run Linux-based operating systems.

    Why do we need supercomputers?

    • Tackle problems: Developed and almost-developed countries have begun ensuring high investments in supercomputers to boost their economies and tackle new social problems.
    • These high-performance computers can simulate the real world, by processing massive amounts of data, making cars and planes safer, and more fuel-efficient and environment-friendly.
    • They also aid in the extraction of new sources of oil and gas, development of alternative energy sources, and advancement in medical sciences.
    • Disaster Management: Supercomputers have also helped weather forecasters to accurately predict severe storms, enable better mitigation planning and warning systems.
    • They are also used by financial services, manufacturing and internet companies and infrastructure systems like water-supply networks, energy grids, and transportation.
    • Future applications of artificial intelligence (AI) also depend on supercomputing.
    • Due to the potential of this technology, countries like the US, China, France, Germany, Japan, and Russia have created national-level supercomputing strategies and are investing substantially in these programmes.

    When did India initiate its efforts to build supercomputers?

    • India’s supercomputer programme initiated in the late 1980s, when the United States ceased the export of a Cray Supercomputer due to technology embargos.
    • This resulted in India setting up C-DAC in 1988, which in 1991, unveiled the prototype of PARAM 800, benchmarked at 5 Gflops. This supercomputer was the second-fastest in the world at that time.
    • Since June 2018, the USA’s Summit is the fastest supercomputer in the world, taking away this position from China.
    • As of January 2018, Pratyush and Mihir are the fastest supercomputers in India with a maximum speed of Peta Flops.

  • Goods and Services Tax (GST)

    Federalism, now a partisan internal dialogue

    | Polity | Mains Paper 2: Federalism

    Against the backdrop of the ongoing tussle between the states and the Centre over the issue of GST compensation, the article analyses the evolution of federalism and power-sharing in India.

    GST and federalism

    • At the first sign of stress, the nation unified in a singular system of taxation (GST) turned into a policy of every-state-for-itself.
    • Evidence of seriously miscued revenue estimates without pragmatic tax rate, was accumulating at an alarming pace.
    • The Comptroller and Auditor-General of India (CAG) recently revealed how a cess meant to remedy shortfalls in GST yields, was retained in central government revenues, in violation of all applicable norms.
    • This revelation does little to build trust between the Centre and the States at a time when the States’ facing lack of resource and the central government is advising them to borrow.
    • Some states believe that the onus of borrowing should rest with the central government.

    Higher borrowing limit for states with conditions

    • The central government sanctioned a higher borrowing limit for States through the current year.
    • In the bargain, it imposed conditionalities:
    • 1) Enforcing a singular standard for the implementation of policies across a vast and diverse country.
    • 2) Improving India’s ranking as a place for “doing business”.
    • States will have unconditional access to borrowings equivalent to half a percentage point of their gross output.
    • But, subsequently, every tranche of a quarter point will be premised on progress in implementing the “one nation, one ration card” scheme, and improvements in the “ease of doing business”.

    Federalism in India

    • Aside from the contents and definitions sections, the word “federal” occurs in only one operational article of the Indian Constitution, in reference to the apex judicial body created in colonial times.
    • When this body was transformed into the Supreme Court at the moment the Constitution came into force, the word seemingly lost all operative value.
    • The distribution of powers and responsibilities between various tiers of the governmental system, was achieved without explicit recognition of federalism as a governing principle.
    • In actual operational terms, the relationship of Centre and States followed different paradigms through various phases of politics.
    •  At the time of Independence, the distribution of powers between Centre and States was transformed into an internal discussion of the Congress.

    Evolution of power-sharing and politics

    • The “Congress system”, as the political scientist Rajni Kothari called it, was seen at one time to have sufficient internal flexibility and resilience to absorb all factional pressures.
    • The first challenge came from the cultural terrain, compelling a reluctant national leadership to accept linguistic reorganisation of States.
    • And then, as ambitions of nation-building through rapid industrialisation resulted in the possibility of a non-Congress politics.
    • The Congress lost power in a number of key States in 1967.
    • The polity moved into a new phase when politics was about “waves” at the national or state level either in favour of, or against the Congress.
    • From 1989 onwards, politics settled into another distinct phase, when outcomes at the national level were the resultant of very separate State-level results.

    Conclusion

    Though federal structure could not be free from Centre-State power struggle, that struggle should not come into the development of the nation. In this context, it is the responsibility of the Centre to address the issues facing the state amid pandemic.

    Need for guidelines for gene-editing research in India

    op-ed snap | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    The Nobel Prize in Chemistry for 2020 has been awarded for the discovery of CRISPR Cas9. The two scientists have pioneered the use of CRISPR  – Cas9 (CRISPR-associated protein 9) system as a gene-editing tool.

    Background of discovery of CRISPR

    • In 1987a group of Japanese researchers observed an unusual homologous DNA sequence bearing direct repeats with spacing in a eubacterial gene.
    • In subsequent years CRISPR was discovered and showed to be a bacterial adaptive immune system and to act on DNA targets.
    • A notable discovery on the use of CRISPR as a gene-editing tool was by a Lithuanian biochemist, Virginijus Šikšnys, in 2012.
    • Šikšnys showed that Cas9 could cut purified DNA in a test tube, the same discovery for which both Charpentier and Doudna were given the credit.
    • Thus, the exclusion of Siksnys from this year’s Nobel is going to raise discussions.

    Issue of gene-edited babies

    • The world was alarmed by such a mission in 2018 when Chinese scientist edited genes in human embryos using the CRISPR-Cas9 system which resulted in the birth of twin girls.
    • The incident became known as the case of the first gene-edited babies of the world.
    • Following the incident, the World Health Organization formed a panel of gene-editing experts.
    • The expert panel suggested a central registry of all human genome editing research in order to create an open and transparent database of ongoing work.

    Guidelines and regulations in India

    • In India, several rules, guidelines, and policies are notified under the Environment Protection Act, 1986 to regulate genetically modified organisms.
    • The above Act and the National Ethical Guidelines for Biomedical and Health Research involving human participants, 2017, by the Indian Council of Medical Research (ICMR), and the Biomedical and Health Research Regulation Bill implies regulation of the gene-editing process.
    • This is especially so in the usage of its language “modification, deletion or removal of parts of heritable material”.
    • However, there is no explicit mention of the term gene editing.

    Consider the question “What is CRISPR-Cas9? How it helps in the gene-editing? What are the concerns with use of it for gene-editing?”

    Conclusion

    It is time that India came up with a specific law to ban germline editing and put out guidelines for conducting gene-editing research giving rise to modified organisms.

    Back2Basics: What is CRISPR?

    • CRISPRs: “CRISPR” stands for “clusters of regularly interspaced short palindromic repeats.”
    • It is a specialized region of DNA with two distinct characteristics: the presence of nucleotide repeats and spacers.
    • Repeated sequences of nucleotides — the building blocks of DNA — are distributed throughout a CRISPR region.
    • Spacers are bits of DNA that are interspersed among these repeated sequences.
    • In the case of bacteria, the spacers are taken from viruses that previously attacked the organism.
    • They serve as a bank of memories, which enables bacteria to recognize the viruses and fight off future attacks.

  • Air Pollution

    Towards cleaner air in Delhi

    op-ed snap | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    The article suggests the three-pronged strategy to deal with the emission from transportation and highlights the importance of coordination at various level to deal with the issue of pollution.

    Anti-pollution campaign in Delhi

    • With air pollution returning to pre-COVID levels, the Delhi administration has launched a major anti-pollution campaign this month.
    • The campaign is focused on cutting the deadly smoke from thermal plants and brick kilns in the National Capital Region as well as on chemical treatment of stubble burning from nearby States.

    Abating emission from transportation

    • Delhi’s long-term solution will depend importantly also on abating emissions from transportation.
    • Delhi needs a 65% reduction to meet the national standards for PM2.5.
    • Vehicles, including trucks and two-wheelers, contribute 20%-40% of the PM2.5 concentrations.
    • Tackling vehicle emissions would be one part of the agenda, as in comparable situations in Bangkok, Beijing, and Mexico City.

    Three-part action to combat emissions from transportation

    • A three-part action comprises emissions standards, public transport, and electric vehicles.

    1) Stricter enforcement of emission controls

    • Two-wheelers and three-wheelers were as important as cars and lorries in Beijing’s experience.
    • Bangkok ramped up inspection and maintenance to cut emissions.
    • The first order of business is to implement the national standards.

    2) Strengthening public transport

    • Bus Rapid Transit (BRT)  around the world show how the sizeable investment cost is more than offset by the benefits, and that financing pays off.
    • Delhi has lessons from its BRT experience in designating better BRT lanes, improving the ticketing system and synchronising with the Metro.
    • The Supreme Court’s ruling to increase Delhi’s bus fleet and align it with the Metro network must be carried out.
    • The ‘odd-even’ number plate policy can help, but the system should reduce exemptions, allow a longer implementation period, and complement it with other measures.

    3) Adoption of electric vehicle: A long term solution

    •  Subsidies and investment will be needed to ensure that EVs are used to a meaningful scale.
    • The Delhi government’s three-year policy aims to make EVs account for a quarter of the new vehicles registered in the capital by 2024.
    • EVs will gain from purchase incentives, scrappage benefits on older vehicles, loans at favourable interest and a waiver of road taxes.

    Need for coordination at various level

    • Transport solutions need to be one part of pollution abatement that includes industry and agriculture.
    • Delhi’s own actions will not work if the pollution from neighbouring States is not addressed head on.
    • Technical solutions need to be underpinned by coordination and transparency across Central, State, and local governments.
    • Public opinion matters.
    • Citizen participation and the media are vital for sharing the message on pollution and health, using data such as those from the Central Pollution Control Board.

    Conclusion

    • It is a matter of prioritising people’s health and a brighter future. Once the pandemic is over, Delhi must not stumble into yet another public health emergency. The time to act is now.

    Freedom of Navigation Operations (FONOPs)

    IOCR | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    Indian Navy is scheduled to hold another Passage Exercise (PASSEX) with the US to undertake Freedom of Navigation Operations (FONOP).

    Try this question:

    Q.What do you mean by Freedom of Navigation Operations (FONOPs)? What are its legal backings?  Discuss its significance.

    Freedom of Navigation Operations

    • FONOPs are closely linked to the concept of freedom of navigation, and in particular to the enforcement of relevant international law and customs regarding freedom of navigation.
    • Freedom of navigation has been thoroughly practised and refined, and ultimately codified and accepted as international law under UNCLOS, in a legal process that was inclusive and consent-based.
    • The drafting of UNCLOS was driven in part by states’ concerns that strong national maritime interests could lead to excessive maritime claims over coastal seas, which could threaten freedom of navigation.
    • FONOPs are outgrowths of this development of international law, based on sovereign equality and international interdependence.

    Significance of FONOPs

    • FONOPs are a method of enforcing UNCLOS (United Nations Convention on the Law of the Sea) and avoiding these negative outcomes by reinforcing freedom of navigation through practice.
    • It is exercised by sailing through all areas of the sea permitted under UNCLOS, and particularly those areas that states have attempted to close off to free navigation as defined under UNCLOS.

    Back2Basics: UNCLOS

    • The Law of the Sea Treaty formally known as the Third United Nations Convention on the Law of the Sea was adopted in 1982 at Montego Bay, Jamaica. It entered into force in 1994.
    • The convention establishes a comprehensive set of rules governing the oceans and to replace previous U.N. Conventions on the Law of the Sea
    • The convention defines the distance of 12 nautical miles from the baseline as Territorial Sea limit and a distance of 200 nautical miles distance as Exclusive Economic Zone limit.

    Q.The term ‘IndARC’, sometimes seen in the news, is the name of:

    (a) An indigenously developed radar system inducted into Indian Defence

    (b) India’s satellite to provide services to the countries of Indian Ocean Rim

    (c) A scientific establishment set up by India in Antarctic region

    (d) India’s underwater observatory to scientifically study the Arctic region

    Indian Sat

    • The Indian Sat is made of reinforced graphene polymer. It is 3 cm in size and weighs 64 gm.
    • It has its own radio frequency communication to transmit and receive a signal from earth to outer space. The solar cells attached to the satellite generate power for it.
    • The photographic film will absorb and measure the cosmic radiation inside the rocket.
    • It would study the effect of reinforced graphene polymers in microgravity. It would be in sub-orbital space flight for a few minutes before landing in the ocean.

    What is micro-gravity?

    • The term micro-g environment is more or less synonymous with the terms weightlessness and zero-g, but with an emphasis on the fact that g-forces are never exactly zero—it is just very small.
    • On the ISS, for example, the small g-forces come from tidal effects, gravity from objects other than the Earth, such as astronauts, the spacecraft, and the Sun, and, occasionally, air resistance.

    Back2Basics: Femto-satellites

    • Femto-satellites are satellites with a mass lower than 100 grams.
    • These new categories of satellites are, by concept, low cost devices if they are based on Commercial-of-the-Shelf (COTS) components.
    • Some examples of applications are related to low-cost missions with a short time of development.

     Kalamsat

    • Kalamsat was a communication satellite with a life span of two months launched in 2017.
    • The nanosatellite is a 10cm cube weighing 1.2 kg.
    • It will be the first to use the rocket’s fourth stage as an orbital platform.

  • Goods and Services Tax (GST)

    The federalism test

    | Polity | Mains Paper 2: Federalism

    The GST has been hailed as the grand bargain and the success story of the federalism. But the economic disruption caused by the pandemic has put it to test. The article deals with the issue of GST compensation.

    Compensating the loss of GST revenue: 2 options

    • In the 41st meeting of the GST Council, the Union government had presented the states with two options.
    • The Centre had estimated the states’ total loss of GST revenue at Rs 3 lakh crore, of which, Rs 65,000 crore was expected to accrue from the compensation cess.
    • Of the remaining Rs 2.35 lakh crore, the loss due to the pandemic was estimated at Rs 1.28 lakh crore.
    • The first option was to provide states a special window to borrow Rs 97,000 crore from the RBI, which was later revised to Rs 1.1 lakh crore.
    • Under this option, both the interest payments and the repayments would be made from future collections of the compensation cess.
    • In the second option, the entire shortfall of Rs 2.35 lakh crore could be borrowed from the market and the states would have to bear the interest costs, but the repayments would be adjusted against future collections of the cess.
    • 10 states have rejected both the options and have stated that it is the Centre’s responsibility to compensate the states, and therefore, it should borrow.

    Commitment of the Centre

    • The minutes of the 7th and 8th GST Council meeting show that most of the states wanted the Centre to commit on paying compensation from the Consolidated Fund of India (CFI).
    • On that demand the Union Finance Minister had stated that in case the amount in the GST compensation fund falls short of the compensation payable in any bi-monthly period, the GST Council shall decide the mode of raising additional resources including borrowing from the market which could be repaid by the collection of cess in the sixth year or further subsequent years.
    • Thus, there was a clear commitment of the Centre on the issue of compensation and the method of recouping the loss.

    Impact on the Centre-State relations

    • The payment of compensation has plunged the Union-state relationship to a new low.
    • First, not recognising the Centre’s commitment will make states wary of any future reforms involving an agreement with the Centre.
    • Second, giving selective press statements to pressurise the states into accepting one or the other option does not infuse confidence.
    • Third, there was a statement by the Union finance ministry officials that the GST Council does not have jurisdiction over-borrowing and borrowing is an individual state and Centre’s decision under Article 293 of the Constitution.
    • If so, why were the two borrowing options presented to the states in the meeting of the Council?

    Way forward

    • It is the Centre’s commitment to find the compensation mechanism and borrowing is one of the options — that must be discussed in the Council.
    • Furthermore, if the commitment of the Centre is recognised as admitted by the finance minister in the 7th GST council meeting, the Centre should take the responsibility to borrow.
    • Both interest payments and repayment of the principal liability can be met from future collections from the cess.

    Conclusion

    This issue is of immense significance for the future of Centre-state relations. But pressuring states on the basis of political strength will have adverse consequences for the country’s federal structure.
