  • Issues with the Gopalakrishnan Committee Report

    The article highlights the importance of non-personal data collected by the government and lack of any reference to it in the Gopalakrishnan Committee report.

    Background

    • The Committee of Experts on the Non-Personal Data Governance Framework headed by K Gopalakrishnan has recommended making privately held non-personal data “open”.
    •  This has raised concerns about state interference in the private data ecoystem.

    Importance of data collected by government agencies

    • The report is a missed opportunity to address the governance frameworks around data created by government agencies.
    • Some of the most important non-personal data sets are held by the government, or result from taxpayer funding.
    • Such data can be useful in either framing public policy or creating and providing new services.

    Why government data should be open to citizens: 5 Reasons

    • First, the state should be transparent about information that it has. This will improve accountability.
    • Second, if taxpayer money has funded any of the data sets, then it is an obligation of the state to return the fruits of that funding to the taxpayer.
    • Third, by permitting the reuse of government data sets, we avoid the need for duplication.
    • Fourth, government data sets, curated according to publicly verified standards, can lead to increased confidence in data quality and increased usage.
    • Finally, free flow of information can have beneficial effects on society in general.

    Government policies promoting openness of data

    • The Right to Information (RTI) Act, 2005, mandates the disclosure of government data on a suo moto basis.
    • One of the nine pillars of the Digital India Policy is “information for all”.
    • The National Data Sharing and Accessibility Policy (NDSAP), 2012 requires all non-sensitive information held by public authorities to be made publicly accessible in machine readable formats (subject to conditions).
    • The government has also set up an Open Government Data Platform to provide open access to data sets held by ministries and other agencies of the government.
    • Various States have also either created their own data portals or have provided data sets to the Open Government Data Platform.

    Challenges in making the data open to society

    • There are two reasons for our failure to create an open data-based society.
    • The first is lack of clarity in some of the provisions of the NDSAP or the relevant implementation guidelines.
    • The second is the inability to enforce guidelines appropriately.
    • Data sets released by governments are often inconsistent, incomplete, outdated, published in non-machine readable or inconsistent formats, include duplicates, and lack quality (or any) metadata, thereby reducing re-usability.

    Issues with Gopalakrishnana Committee Report

    • The Gopalakrishnan Committee could have evaluated what is going wrong with existing policies and practice pertaining to government data.
    • The report is a missed opportunity to address the governance frameworks around non-personal data sets in a country created by government agencies, or those resulting from taxpayer money.
    • The report largely focuses on the dangers posed by data collection by private sector entities.
    • This has raised concerns about state interference in the private data ecoystem.
    • Many of the concerns that should be addressed in the report that are central to the governance of the data ecosystem have remained in the background.
    • For instance, India’s cybersecurity framework continues to be inadequate, while even the Justice B.N. Srikrishna Committee report of 2018 highlighted the need to restrict the growing power of the state to carry out surveillance.

    Consider the question “What are the key recommendation made by the Gopalakrishnan Committee for the regulation of non-personal data? What are the shortcomings in of the report in your opinion?”

    Conclusion

    Since data governance is a relatively new concept in India, the government would be better served in taking an incremental approach to any perceived problems. This should begin with reforming how the government itself deals with citizens’ data.

  • Pinaka Missile System

    The Ministry of Defence (MoD) has signed contracts with three Indian companies for supply of six regiments of the Pinaka Rocket System to be deployed along borders with Pakistan and China.

    Following things are crucial to know about the Pinaka Missile System:

    1) It’s development and manufacture

    2) Fire Range and other capabilities

    3) Latest technology enhancement

    Pinaka Missile System

    • Pinaka is an indigenously developed rocket system named after Lord Shiva’s mythological bow.
    • It is used for attacking the adversary targets prior to the close-quarter battles which involve smaller range artillery, armoured elements and the infantry.
    • The development of the Pinaka was started by the DRDO in the late 1980s, as an alternative to the multi-barrel rocket launching systems of Russian make, called like the ‘Grad’, which are still in use.
    • After successful tests of Pinaka Mark-1 in late 1990, it was first used in the battlefield during the Kargil War of 1999, quite successfully.
    • Subsequently, multiple regiments of the system came up over the 2000s.

    Its versions and capabilities

    • The Pinaka, which is primarily a multi-barrel rocket system (MBRL) system, can fire a salvo of 12 rockets over a period of 44 seconds.
    • One battery of the Pinaka system consists of six launch vehicles, accompanied by the loader systems, radar and links with network-based systems and a command post.
    • It can neutralize an area one kilometre by one kilometre.
    • The Mark-I version of Pinaka has a range of around 40 kilometres and the Mark-II version can fire up to 75 kilometres.
    • The Mark-II version of the rocket has been modified as a guided missile system by integrating it with the navigation, control and guidance system to improve the end accuracy and increase the range.
    • The navigation system of the missile is linked with the Indian Regional Navigation Satellite System.

  • What is Carbon-14 (C14) Battery?

    A California-based company has made a self-charging battery, which can run for 28,000 years on a single charge, by trapping carbon-14 (C14) nuclear waste in artificial diamond-case.

    Try this PYQ:

    Q.The known forces of nature can be divided into four classes, viz. gravity, electromagnetism, weak nuclear force and strong nuclear force. With reference to them, which one of the following statements is not correct?

    (a) Gravity is the strongest of the four

    (b) Electromagnetism act only on particles with an electric charge

    (c) Weak nuclear force causes radioactivity

    (d) Strong nuclear force holds protons and neutrons inside the nuclear of an atom.

    What is C14?

    • Carbon-14 (14C), or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
    • There are three naturally occurring isotopes of carbon on Earth: carbon-12, which makes up 99% of all carbon on Earth; carbon-13, which makes up 1%; and carbon-14, which occurs in trace amounts.
    • Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.

    C14 battery

    • The battery works by generating electricity on its own from a shower of electrons as a result of radioactive decay scattered and deposited in the artificial diamond-case.
    • The battery can be used in electric vehicles, mobile phones, laptops, tablets, drones, watches, cameras, health monitors and even sensors.
    • It is also said to be extremely safe and tamper-proof as it is coated with a non-radioactive diamond which prevents radiation leaks.

    Best example of nuke waste recycling

    • It is estimated that 33 million cubic metres of global nuclear waste will cost over $100 billion to manage and dispose of.
    • And a lot of this waste is graphite that is one of the higher risks of radioactive waste and one of the most expensive and problematic waste to store.

    Its applications

    • The company says its battery can be used to powerhouses, and that any excess electricity generated can be sold to the grid.
    • As the new battery need not be replaced, it can be installed in hard to reach places like pacemakers and implants, where a regular change of battery is not possible.
    • Another area of use is space electronics. The battery is said to power space equipment in rockets.
    • It can power the electrical needs of space crafts, like providing power to cockpits and assisting launch into the upper atmosphere.

  • [pib] Historic City of Hampi

    The Ministry of Tourism organised their latest webinar titled Hampi- Inspired by the past; Going into the future under Dekho Apna Desh Webinar series.

    Try this PYQ:

    Q.Building ‘Kalyaana Mandapas’ was a notable feature in the temple construction in the kingdom of-

    (a) Chalukya

    (b) Chandela

    (c) Rashtrakuta

    (d) Vijayanagara

    Facts about Hampi

    • Its name is derived from Pampa which is the old name of the Tungabhadra River on whose banks the city is built.
    • In 1336 CE, the Vijayanagara Empire arose from the ruins of the Kampili kingdom.
    • It grew into one of the famed Hindu empires of South India that ruled for over 200 years.
    • The Vijayanagara rulers fostered developments in intellectual pursuits and the arts, maintained a strong military and fought many wars with sultanates to its north and east.
    • They invested in roads, waterworks, agriculture, religious buildings and public infrastructure.
    • The site used to be multi-religious and multi-ethnic; it included Hindu and Jain monuments next to each other.
    • The buildings predominantly followed South Indian Hindu arts and architecture dating to the Aihole-Pattadakal styles.
    • The Hampi builders also used elements of Indo-Islamic architecture in the Lotus Mahal, the public bath and the elephant stables.

    Major attractions

    • One of the major attractions of Hampi is the 15th Century Virupaksha temple which is one of the oldest monuments of the town.
    • The main shrine is dedicated to Virupaksha, a form of Lord Shiva.
    • Hemkunta Hill, south of the Virupaksha temple contains early ruins, Jain temples and a monolithic sculpture of Lord Narasimha, a form of Lord Vishnu.
    • At the eastern end, there is the large Nandi in stone; on the southern side is the larger than life Ganesha.
    • Large single stone carvings seem to have been the fashion of the day in Hampi, for there is a large image of Narasimha (6.7m high), the half-lion half-man incarnation of God, as well as a huge linga.

  • Space industry and challenges

    The article analyses opportunities and challenges the outer space technology offers to us.

    Emerging trends in space industry

    • The price for reaching low Earth orbit has declined by a factor of 20 in a decade.
    • It enhances human space travel possibilities by leveraging new commercial capabilities.
    • According to a Bank of America Report, the $350 billion space market today will touch $2.7 trillion by 2050.
    • Starlink, the constellation being constructed by SpaceX to provide global Internet access, plans more than 10,000 mass-produced small satellites in low Earth orbit. 
    •  In a decade, 80,000 such satellites could be in space compared to less than 3,000 at present.
    • Companies such as Planet, Spire Global and Iceye are using orbital vantage points to collect and analyse data to deliver fresh insights in weather forecasting, global logistics, crop harvesting and disaster response.
    • Space could prove attractive for high-tech manufacturing too.
    • In short, an exciting new platform is opening up for entrepreneurs.

    3 Challenges

    1) Governance of outer space

    • Framework for governance of outer space as it becomes democratised, commercialised and crowded is becoming obsolescent.
    • The Outer Space Treaty of 1967 enshrines the idea that space should be “the province of all mankind” and “not subject to national appropriation by claims of sovereignty”.
    • The Rescue Agreement, Space Liability Convention, and the Space Registration Convention expanded provisions of the Outer Space Treaty.
    • The Moon Treaty of 1979 was not ratified by major space-faring nations.
    • Space law does not have a dispute settlement mechanism, is silent on collisions and debris, and offers insufficient guidance on interference with others’ space assets.
    • These gaps heighten the potential for conflict in an era of congested orbits and breakneck technological change.

    2) Acknowledging role of non-state entities

    • The legal framework related to outre space is state-centric, placing responsibility on states alone.
    • However, non-state entities are now in the fray for commercial space exploration and utilisation.
    • Some states are providing frameworks for resource recovery through private enterprises.
    • Some scholars and governments view this as against the principle of national non-appropriation, violating the spirit if not the letter of the existing space law.
    • The lack of alignment of domestic and international normative frameworks risks a damaging free-for-all competition for celestial resources involving actors outside the space framework.

    3) The arms race in outer space

    • The space arms race is difficult to curb, especially since almost all space technologies have military applications.
    • For example, satellite constellations are commercial but governments could acquire their data to monitor military movements.
    • Investment in technologies that can disrupt or destroy space-based capabilities is under way.
    • Despite concerns about military activity in outer space for long, not much progress has been made in addressing them.
    • The UN General Assembly passes a resolution on Prevention of an Arms Race in Outer Space since 1982.
    • The current geopolitical situation does not hold hope for addressing concerns of a space arms race.

    Need for space legislation in India

    • India has invested enormous resources in its space programme through the Indian Space Research Organisation.
    • More importantly, our space assets are crucial for India’s development.
    • The proposed involvement of private players and the creation of an autonomous body IN-SPACe for permitting and regulating activities of the private sector are welcome efforts.
    • However, the space environment that India faces requires us to go beyond meeting technical milestones.
    • We need a space legislation enabling coherence across technical, legal, commercial, diplomatic and defence goals.

    Consider the question “Outer space technology is expanding its horizon day by day. However, there are certain challenges the expansion of the space technology faces. What are these challenges and suggest ways to deal with such challenges.”

    Conclusion

    Our space vision also needs to address global governance, regulatory and arms control issues. As space opens up our space vision needs broadening too.

    (a) Chalukya

    (b) Chandela

    (c) Rashtrakuta

    (d) Vijayanagara

    About Lingaraj Temple

    • Lingaraja Temple is a temple dedicated to Shiva and is one of the oldest temples in Bhubaneswar, Odisha.
    • It represents the quintessence of the Kalinga Architecture and culminating the medieval stages of the architectural tradition at Bhubaneswar.
    • The temple is believed to be built by the kings from the Somavamsi dynasty, with later additions from the Ganga rulers.
    • It is built in the Deula style that has four components namely, vimana (structure containing the sanctum), jagamohana (assembly hall), natamandira (festival hall) and bhoga-mandapa (hall of offerings), each increasing in the height to its predecessor.

    • Bhubaneswar is called the Ekamra Kshetra as the deity of Lingaraja was originally under a mango tree (Ekamra) as noted in Ekamra Purana, a 13th-century Sanskrit treatise.
    • The temple has images of Vishnu, possibly because of the rising prominence of Jagannath sect emanating from the Ganga rulers who built the Jagannath Temple in Puri in the 12th century.

  • Dwarf Planet Ceres

    The dwarf planet Ceres, which lies in the asteroid belt between Mars and Jupiter now, has the status of an “ocean world”.

    Note various dwarf planets and the criteria making a planet dwarf, as mentioned in the B2b section.

    Ceres exploration

    • The dwarf planet was first spotted by Giuseppe Piazzi in 1801, who assumed that Ceres was the missing planet between Mars and Jupiter.
    • It was classified as a dwarf planet in 2006 and is the first dwarf planet to be orbited by a spacecraft.
    • In 2015, NASA’s Dawn reached it to study its surface, composition and history.

    What does it mean to be an “ocean world”?

    • With a crust that mixes ice, salts, rock-forming minerals and other materials, Ceres looks to be a remnant “ocean world,” wearing the chemistry of its Old Ocean and records of the interaction on its surface.
    • The observations from Dawn suggest the presence of briny liquid (saltwater) water under Ceres’s surface.
    • Scientists have determined that Ceres has a brine reservoir located about 40 km deep and which is hundreds of miles wide, making the dwarf planet, “water-rich”.

    Why do researchers study Ceres?

    • Scientists are interested in this dwarf planet because it hosts the possibility of having water, something that many other planets do not have.
    • Therefore, scientists look for signs of life on Ceres, a possibility that has also maintained scientists’ interest in the planet Mars, whose atmosphere was once warm enough to allow water to flow through it.
    • Another reason why scientists are interested in that studying it can give insights about the formation of the Solar System since it is considered to be a fossil from that time.

    Back2Basics: Dwarf Planets

    • As of today, there are officially five dwarf planets in our Solar System.
    • The most famous is Pluto, downgraded from the status of a planet in 2006.
    • The other four, in order of size, are Eris, Makemake, Haumea and Ceres. The sixth claimant for a dwarf planet is Hygiea, which so far has been taken to be an asteroid.
    • These four criteria are – that the body orbits around the Sun, it is not a moon, has not cleared the neighbourhood around its orbit and has enough mass for its gravity to pull it into a roughly spherical shape.

  • [pib] Sarabhai Crater

    The Indian Space Research Organization (ISRO) has named a crater captured by Chandrayaan 2 Orbiter after Vikram Sarabhai.

    Try this PYQ:

    What do you understand by the term Aitken Basin? (CSP 2012)

    (a) It is a desert in southern Chile which is known to be the only location on earth where no rainfall takes place

    (b) It is an impact crater on the far side of the Moon

    (c) It is a Pacific coast basin, which is known to house large amounts of oil and gas

    (d) It is a deep hypersaline anoxic basin where no aquatic animals are found

    Sarabhai Crater

    • “Sarabhai” Crater is named after Dr Vikram Sarabhai and around 250 to 300 kilometres east of this Crater is where the Apollo 17 and Luna 21 Missions had landed.
    • The crater captured in 3D images shows that the Crater has a depth of around 1.7 Kms taken from its raised rim and the slope of Crater walls is in between 25 to 35 degree.
    • These findings will help the Space Scientists to understand further the process of the lunar region filled with lava.

    Who was Vikram Sarabhai?

    • Sarabhai was an Indian physicist and astronomer who initiated space research and helped develop nuclear power in India.
    • He is internationally regarded as the Father of the Indian Space Program.
    • Known as the cradle of space sciences in India, the Physical Research Laboratory (PRL) was founded in 1947 by him. He was the founder of ISRO.
    • He started a project for the fabrication and launch of an Indian satellite.
    • As a result, the first Indian satellite, Aryabhata, was put in orbit in 1975 from a Russian cosmodrome.
