  • Modern Indian History-Events and Personalities

    How India adopted its military flags and badges based on Lord Mountbatten’s suggestions?

    Prelims Only | | Mains Paper 1: Modern Indian History

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Flags and defence insignia

    Mains level: Not Much

    The new Naval Ensign (flag), which will be unveiled by PM in Kochi, has brought into focus the flags and ranks adopted by the Indian military after Independence.

    Do you know?

    The octagonal shape with twin golden borders draws inspiration from the seal of the great Indian emperor, Chhatrapati Shivaji Maharaj, whose visionary maritime outlook established a credible naval fleet

    Why in news?

    • Documents accessed from National Archives of India show that Lord Mountbatten, former Viceroy and Governor General of India, played a major role in suggesting new flags and rank badges.
    • This was when India was about to become a Republic on January 26, 1950.

    When did India switch from British-era flags and ranks?

    • The switch from British-era flags and ranks took place when India became a Republic (26th Jan, 1950).
    • Prior to that the flags and badges of ranks of the military were of the British pattern.
    • The new, Indian pattern of flags of Army, Navy and Air Force, and also the Regimental Flags of the Army and badges of ranks of all three services were adopted on January 26, 1950.
    • The ‘Kings Commission’ granted to Indian military officers was also changed to ‘Indian Commission’ on the same date.
    • And at a subsequent date the King’s Colours of the various Regiments were laid to rest in Indian Military Academy (IMA), Dehradun.

    When did Lord Mountbatten come into the picture?

    • The national archives have files, dated 1949, that include a detailed note from Lord Mountbatten regarding names, flags and ranks of the armed forces, and then PM Nehru’s letter to the then Defence Minister Baldev Singh regarding Mountbatten’s suggestions.
    • The note, archives reveal, was given to Nehru by Lord Mountbatten when the two met in London.
    • The note was forwarded from the PM’s office to the office of then Governor General C Rajagopalachari on May 24, 1949, stating that it is on the issue of ‘Names and Insignia of Indian Armed Forces’ after India becomes a Republic.
    • The letter also stated that the note should be placed before the Governor General.

    What did Lord Mountbatten say in the note?

    • The note begins by saying that consequent to becoming a Republic the word ‘Royal’ shall be dropped from India’s Army, Navy and Air Force.
    • Mountbatten strongly recommended that no other word like ‘State’ of ‘Republican’ should replace the word ‘Royal’.
    • This was because it would have the effect of separating the forces of India psychologically from the other services in the Commonwealth.
    • He further suggested in the letter that the Crown should be replaced from the insignias and replaced by the “three lions of Ashoka”.
    • Regarding the Naval Ensign, he said that all Commonwealth navies fly the same flag which consists of a large white flag with a red-cross and Union Jack in the upper corner nearer the staff and is known as the ‘White Ensign’.
    • The new Ensign, the note suggested, should continue to have the red-cross but the Indian national flag should replace the Union Jack.
    • He suggested this to maintain commonality with the Commonwealth flags.

    What changes did Mountbatten suggest for uniforms?

    • He strongly urged that existing uniforms should be changed as little as possible.
    • He added that the Crown worn on badges of ranks of Majors and above should be replaced by the “three lions of Ashoka”.
    • The Star of the Order of the Bath should be replaced by Star of India or another form of star.
    • He also suggested that the crossed sword and baton on the badges of ranks of Generals should be retained.
    • The former Viceroy advocated retaining the stripes of rank in Navy and Air Force saying these were internationally almost the same.

    How did the Indian government react to Mountbatten’s suggestions?

    • Nehru wrote to the then defence minister in September 1949 saying that he agreed with the suggestions made by the former Governor General that there should be as little change as possible.
    • The then PM particularly mentioned the changes suggested by Mountbatten for the Navy.
    • Then Governor General C Rajagopalachari also wrote back to Nehru in May 1949 itself agreeing to Mountbatten’s suggestions.
    • In the end, Mountbatten’s suggestions were virtually all accepted and implemented with effect from January 26, 1950.

    Rohini RH-200: ISRO eyeing 200th successful launch of Rohini RH-200

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

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Rohini

    Mains level: Not Much

    rohini

    In a few weeks’ time, the Indian Space Research Organisation (ISRO) hopes to achieve a remarkable feat — the 200th successful launch of the Rohini RH-200 sounding rocket in a row.

    Rohini RH-200

    • RH-200 is a two-stage rocket capable of climbing to a height of 70 km bearing scientific payloads.
    • The first and second stages of RH-200 are powered by solid motors. The ‘200’ in the name denotes the diameter of the rocket in mm.
    • Other operational Rohini variants are RH-300 Mk-II and RH-560 Mk-III.
    • For years, the RH-200 rocket had used a polyvinyl chloride (PVC)-based propellant.
    • The first RH-200 to use a new propellant based on hydroxyl-terminated Polybutadiene (HTPB) was successfully flown from the TERLS in September 2020.
    • The first and second stages of RH200 rocket are powered by solid motors.
    • Since inception of RH200 rocket, both solid stages are processed using polyvinyl chloride (PVC) based propellant.
    • As compared to PVC based propellants, HTPB based propellant is more energetic, higher mechanical & interface properties and has less defects due to lower processing temperature.

    What basically is a Sounding Rocket?

    • A sounding rocket is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight.
    • The rockets are used to launch instruments from 48 to 145 km above the surface of the Earth, the altitude generally between weather balloons and satellites.
    • The maximum altitude for balloons is about 40 km and the minimum for satellites is approximately 121 km.

    History of sounding rockets in India

    • Sounding rockets have an important place in the ISRO story.
    • The first sounding rocket to be launched from Thumba was the American Nike-Apache — on November 21, 1963.
    • After that, two-stage rockets imported from Russia (M-100) and France (Centaure) were flown. The ISRO launched its own version — Rohini RH-75 — in 1967.
    • The ISRO has launched more than 1,600 RH-200 rockets so far.
    • Currently, the RH200, RH300 MkII and RH560 Mk-III rockets are operational which were developed during the early phase of our journey in rocketry.

  • Tribes in News

    Odisha offering cash incentive for PVTGs Marriages

    Prelims Only | Governance | Mains Paper 2: Laws, Institutions & Bodies Constituted For The Vulnerable Sections

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: PVTGS

    Mains level: Not Much

    Keeping the rampant child marriages among the Particularly Vulnerable Tribal Groups (PVTGs) of Odisha in mind, the State government is providing an incentive of ₹20,000 to the couples marrying after the age of 18 years.

    Particularly Vulnerable Tribal Groups (PVTGs)

    • There are certain tribal communities who have declining or stagnant population, low level of literacy, pre-agricultural level of technology and are economically backward.
    • They generally inhabit remote localities having poor infrastructure and administrative support.
    • These groups are among the most vulnerable section of our society as they are few in numbers, have not attained any significant level of social and economic development.
    • 75 such groups have been identified and categorized as Particularly Vulnerable Tribal Groups (PVTGs).

    Origin of the concept

    • The Dhebar Commission (1960-1961) stated that within Scheduled Tribes there existed an inequality in the rate of development.
    • During the fourth Five Year Plan a sub-category was created within Scheduled Tribes to identify groups that considered to be at a lower level of development.
    • This was created based on the Dhebar Commission report and other studies.
    • This sub-category was named “Primitive tribal group”.

    Features of PVTGs

    • The features of such a group include a:
    1. Pre-agricultural system of existence
    2. Practice of hunting and gathering
    3. Zero or negative population growth
    4. Extremely low level of literacy in comparison with other tribal groups
    • Groups that satisfied any one of the criterion were considered as PTG.
    • In 2006 the government of India proposed to rename “Primitive tribal group” as Particularly vulnerable tribal group”.

     

    Try this PYQ:

    Q.Consider the following statements about Particularly Vulnerable Tribal Groups (PVTGs) in India:

    1. PVTGs reside in 18 States and one Union Territory.

    In news: Sittanavasal Rock Cave Temple

    Prelims Only | History | Mains Paper 1: Arts & Culture

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Sittanavasal

    Mains level: NA

    Sittanavasal

    The Sittanavasal Rock Cave Temple, a major centre of Jain influence for 1,000 years just before the Christian era, is in need of better upkeep.

    Sittanavasal

    • Sittanavasal is a small hamlet in Pudukkottai district of Tamil Nadu, India.
    • It is known for the Sittanavasal Cave, a 2nd-century Jain cave complex. From the 7th to the 9th century A.D., the village flourished as a Jain centre.
    • Sittanavasal is the name used synonymously for the hamlet and the hillock that houses the:
    1. Arivar Kovil (temple of Arihants — Jains who conquered their senses)
    2. Ezhadipattam (a cavern with 17 polished rock beds), megalithic burial sites and the
    3. Navachunai tarn (small mountain lake) with a submerged shrine

    What makes it special?

    • The artwork on the ceiling of the sanctum and the ardha mandapam of Arivar Kovil is an early example of post-Ajanta cave paintings of the fourth to sixth centuries.
    • It was also done using the fresco-secco technique (a process that dispenses with preparation of the wall with wet plaster).

    Features of the cave paintings

    • The ceiling paintings show ‘bhavyas’ (exalted souls who work to achieve moksha or spiritual liberation) enjoying themselves in a pool, full of lotuses; today much of it is obscured by patchy plastering.
    • Faint outlines linger of dancing girls on the ‘ardha mandapam’ pillars.
    • The colours are a mixture of plant dyes and mineral elements such as lime, lamp black, and clay pigments such as ochre for yellow and terre verte for the greyish-green tints.

    Why in news now?

    • Unrestricted public access and general exposure to the elements have led to a gradual fading away of these paintings.
    • At the Ezhadipattam, inscriptions have been vandalised beyond recognition.

    Also try this PYQ:

    Q.There are only two known examples of cave paintings of the Gupta period in ancient India. One of these is paintings of Ajanta caves. Where is the other surviving example of Gupta paintings?

    What is National Automated Fingerprint Identification System (NAFIS)?

    Prelims Only | Science Tech | Mains Paper 2: Governance, Transparency & Accountability, Citizens Charters

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: NAFIS

    Mains level: Not Much

    The Union Home Minister has inaugurated the National Automated Fingerprint Identification System (NAFIS).

    What is NAFIS?

    • NAFIS is developed by the National Crime Records Bureau (NCRB) at the Central Fingerprint Bureau (CFPB) in New Delhi.
    • The project is a country-wide searchable database of crime- and criminal-related fingerprints.
    • The web-based application functions as a central information repository by consolidating fingerprint data from all states and Union Territories.
    • In April this year, Madhya Pradesh became the first state in the country to identify a deceased person through NAFIS.

    Utility of NAFIS

    • It enables law enforcement agencies to upload, trace, and retrieve data from the database in real time on a 24×7 basis.
    • It would help in the quick and easy disposal of cases with the help of a centralised fingerprint database.

    How does it work?

    • NAFIS assigns a unique 10-digit National Fingerprint Number (NFN) to each person arrested for a crime.
    • This unique ID will be used for the person’s lifetime, and different crimes registered under different FIRs will be linked to the same NFN.
    • The 2020 report states that the ID’s first two digits will be that of the state code in which the person arrested for a crime is registered, followed by a sequence number.
    • By automating the collection, storage, and matching of fingerprints, along with digitizing the records of fingerprint data, NAFIS will provide the much-needed unique identifier for every arrested person.
    • It will be included in the CCTNS (Crime and Criminal Tracking Network & Systems) database as both are connected at the backend.

    Is this the first time that such an automation project is being attempted?

    • Upon the recommendations of the National Police Commission in 1986, the Central Fingerprint Bureau first began to automate the fingerprint database.
    • It began with digitizing the existing manual records through India’s first Automated Fingerprint Identification System (AFI) in 1992, called Fingerprint Analysis & Criminal Tracing System (FACTS 1.0).
    • The latest iteration, FACTS 5.0, which was upgraded in 2007, was considered to have “outlived its shelf life”, according to a 2018 report by the NCRB and thus needed to be replaced by NAFIS.

    Since when has India relied on fingerprinting as a crime-fighting tool?

    • A system of fingerprinting identification first emerged in colonial India, where it was tested before it spread to Europe and beyond.
    • At first, it was used by British colonial officials for administrative rather than criminal purposes.
    • William Herschel, the chief administrator of the Hooghly district of Bengal, from the late-middle 1800s onwards, used fingerprinting to reduce fraud and forgeries.
    • It then aimed to ensure that the correct person was receiving government pensions, signing land transfer deeds, and mortgage bonds.
    • Anthropometry, the measurement of physical features of the body, was used by officials in India but was soon replaced with a system of fingerprints.

  • Climate Change Impact on India and World – International Reports, Key Observations, etc.

    What is International Argo Program?

    Prelims Only | Enviro & Biodiversity | Mains Paper 1: Important Geophysical Phenomena

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Argo

    Mains level: Not Much

    argo

    The International Argo Program system to observe carbon concentration in the world’s oceans is extremely inadequate to meet the growing and urgent need for information on oceanic carbon, says a report.

    What is Argo?

    • Argo is an international program that uses profiling floats to observe temperature, salinity, currents, and, recently, bio-optical properties in the Earth’s oceans; it has been operational since the early 2000s.
    • The real-time data it provides is used in climate and oceanographic research.
    • A special research interest is to quantify the ocean heat content (OHC).
    • Each instrument (float) spends almost all its life below the surface.
    • The name Argo was chosen because the array of floats works in partnership with the Jason earth observing satellites that measure the shape of the ocean surface.
    • In Greek mythology Jason sailed on his ship the Argo in search of the Golden Fleece.

    What are its aims?

    • The data that Argo collects describes the temperature and salinity of the water and some of the floats measure other properties that describe the biology/chemistry of the ocean.
    • The main reason for collecting these data is to help us understand the oceans’ role in earth’s climate.
    • For example, the changes in sea level (once the tides are averaged out) depend partly on the melting of icecaps and partly on the amount of heat stored in the oceans.
    • Argo’s temperature measurements allow us to calculate how much heat is stored and to monitor from year to year how the distribution of heat changes with depth and from area to area.
    • As ocean heat content increases, sea level rises, just like the mercury in a thermometer.

    How does it work?

    • Each Argo float (costing between $20,000 and $150,000 depending on the individual float’s technical specification) is launched from a ship.
    • The float’s weight is carefully adjusted so that, as it sinks, it eventually stabilizes at a pre-set level, usually 1 km.
    • Ten days later, an internal battery-driven pump transfers oil between a reservoir inside the float and an external bladder.
    • This makes the float first descend to 2km and then return to the surface measuring ocean properties as it rises.
    • The data and the float position are relayed to satellites and then on to receiving stations on shore.
    • The float then sinks again to repeat the 10 day cycle until its batteries are exhausted.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Ambedkar Tourist Circuit

    Mains level: Not Much

    The Central government has announced a special tourist circuit encompassing five key sites associated with Dr. B.R. Ambedkar.

    Why in news?

    • Activists have urged that Mahad, located in Raigad District of Maharashtra, famous for Mahad Lake Satyagraha should also be included in the proposed circuit.

    Ambedkar Circuit

    • The five cities in the tourist circuit as announced are Mhow (his birthplace), London (where he resided and studied), Nagpur (also studied here), Delhi (where he passed away) and finally Mumbai (where he was cremated).
    • With a special AC train, the government is looking to trace the footsteps of Ambedkar in India by giving better connectivity to four of these spots.
    • The idea is to attract tourists beyond the Dalit community, who mostly visit these places as a pilgrimage.
    • The journey will include meals, ground transportation, and entry to the sites.

    About the sites

    1. Janma Bhoomi– Ambedkar’s birthplace in Madhya Pradesh’s Mhow
    2. Shiksha Bhoomi– the place in London where he stayed while studying in the UK
    3. Deeksha Bhoomi– the place in Nagpur where he embraced Buddhism
    4. Mahaparinirvan Bhoomi- the place of his demise in Delhi and
    5. Chaitya Bhoomi- the place of his cremation in Mumbai

    Back2Basics: Tourism Circuits

    • The government had identified 15 tourist circuits under the Swadesh Darshan Scheme in 2014-15.
    • Besides the Ramayana and Buddhist Circuits, others include Coastal Circuit, Desert Circuit, Eco Circuit, Heritage, North East, Himalayan, Sufi, Krishna, Rural, Tribal, and Tirthankar Circuits.
    • In terms of train collaboration, the Ramayana, Buddhist, and North East Circuits are already active, while Ambedkar will be fourth.

    New Account Settlement System for Stock Trading

    Prelims Only | Economics | Mains Paper 3: Indian Economy

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Account settlement, T+1

    Mains level: NA

    Beginning October 1, the new account settlement system for the stock broking industry will kick in under the new guidelines issued by the Securities and Exchange Board of India (SEBI).

    What is Settlement of Accounts?

    • The SEBI mandates stockbrokers to settle i.e., transfer the available credit balance from trading account to bank account, at least once in a quarter (90 days) or 30 days.
    • The process of transferring the unutilised funds back into the bank account is called ‘Running Account Settlement’ or ‘Quarterly Settlement of Funds’.
    • The funds are transferred back to the primary bank account of the customer that is linked to the trading account.
    • As per the latest guidelines, the settlement will now be done on the first Friday of the quarter or the month depending upon the option selected by the customer.

    What are SEBI’s new settlement guidelines?

    • On July 27, SEBI issued new guidelines on running accounts of client funds and securities lying with the broker.
    • As per the new guidelines, with effect from October 1, 2022, the settlement of running account of clients’ funds will be done by the trading members after considering the end of the day (EOD) obligation of funds.
    • In cases where the client has opted for a monthly settlement process, then the running account shall be settled on the first Friday of every month.

    How will it impact investors and traders?

    • Changes in settlement brought in by SEBI over the last few years have had the aim of protecting the investor and preventing the misuse as money lying in trading accounts of investors for long periods.
    • SEBI’s move will give certainty to investors and trading members.
    • It will help brokers develop a system just like banks, which credit interest in the accounts of their customers at the end of the quarter.
    • Another advantage would be that if a customer has more than one demat account with different brokers, having one settlement date for the entire industry will make it easier for her to keep track of her funds.

    Back2Basics: Securities and Exchange Board of India (SEBI)

    • The SEBI is the regulatory body for securities and commodity market in India under the jurisdiction of Ministry of Finance Government of India.
    • It was established on 12 April 1988 and given Statutory Powers on 30 January 1992 through the SEBI Act, 1992.

    Jurisdiction of SEBI

    • SEBI has to be responsive to the needs of three groups, which constitute the market:
    1. Issuers of securities
    2. Investors
    3. Market intermediaries

    SEBI has three powers rolled into one body: quasi-legislative, quasi-judicial and quasi-executive.

    • It drafts regulations in its legislative capacity, it conducts investigation and enforcement action in its executive function and it passes rulings and orders in its judicial capacity.
    • Though this makes it very powerful, there is an appeal process to create accountability.
    • There is a Securities Appellate Tribunal which is a three-member tribunal and is currently headed by Justice Tarun Agarwala, former Chief Justice of the Meghalaya High Court.
    • A second appeal lies directly to the Supreme Court.

    Mains level: Not Much

    dart

    In the first-of-its kind NASA’s DART Mission is about to hit a small, harmless asteroid millions of miles away.

    What is DART Mission?

    • The main aim of the mission is to test the newly developed technology that would allow a spacecraft to crash into an asteroid and change its course.
    • It is a suicide mission and the spacecraft will be completely destroyed.
    • The target of the spacecraft is a small moonlet called Dimorphos (Greek for “two forms”).
    • It is about 160-metre in diameter and the spacecraft is expected to collide when it is 11 million kilometres away from Earth.
    • Dimorphos orbits a larger asteroid named Didymos (Greek for “twin”) which has a diameter of 780 metres.

    Why Dimorphos?

    • Didymos is a perfect system for the test mission because it is an eclipsing binary which means it has a moonlet that regularly orbits the asteroid.
    • It is observable when it passes in front of the main asteroid.
    • Earth-based telescopes can study this variation in brightness to understand how long it takes Dimorphos to orbit Didymos.

    Collision course

    • At the time of impact, Didymos and Dimorphos will be relatively close to Earth – within 6.8 million miles (11 million kilometers).
    • The spacecraft will accelerate at about 24,140 kilometers per hour when it collides with Dimorphos.
    • It aims to crash into Dimorphos to change the asteroid’s motion in space.
    • This collision will be recorded by LICIACube, or Light Italian CubeSat for Imaging of Asteroids, a companion cube satellite provided by the Italian Space Agency.
    • Three minutes after impact, the CubeSat will fly by Dimorphos to capture images and video.

    Why such mission?

    • Dimorphos was chosen for this mission because its size is relative to asteroids that could pose a threat to Earth.
    • The spacecraft is about 100 times smaller than Dimorphos, so it won’t obliterate the asteroid.
    • The fast impact will only change Dimorphos’ speed as it orbits Didymos by 1%, which doesn’t sound like a lot — but it will change the moon’s orbital period.
