  • ISRO Missions and Discoveries

    What is PSLV Orbital Experimental Module (POEM)?

    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: POEM

    Mains level: Not Much

    The ISRO has launched three Singaporean satellites in precise orbit through the PSLV Orbital Experimental Module or ‘POEM’.

    What is POEM?

    • The POEM is a platform that will help perform in-orbit experiments using the final, and otherwise discarded, stage of ISRO’s workhorse rocket, the Polar Satellite Launch Vehicle (PSLV).
    • The PSLV is a four-stage rocket where the first three spent stages fall back into the ocean, and the final stage (PS4) — after launching the satellite into orbit — ends up as space junk.
    • However, in PSLV-C53 mission, the spent final stage will be utilised as a “stabilised platform” to perform experiments.
    • POEM is carrying six payloads, including two from Indian space start-ups Digantara and Dhruva Space.

    Features of POEM

    • POEM has a dedicated Navigation Guidance and Control (NGC) system for attitude stabilisation, which stands for controlling the orientation of any aerospace vehicle within permitted limits.
    • The NGC will act as the platform’s brain to stabilize it with specified accuracy.
    • POEM will derive its power from solar panels mounted around the PS4 tank, and a Li-Ion battery.
    • It will navigate using four sun sensors, a magnetometer, gyros & NavIC.
    • It carries dedicated control thrusters using Helium gas storage. It is enabled with a telecomm and feature.

    Has ISRO repurposed and used PS4 rocket junk earlier?

    • The Indian space agency first demonstrated the capability of using PSLV-C44 as an orbital platform in 2019.
    • It injected Microsat-R and Kalamsat-V2 satellites into their designated orbits.
    • The fourth stage in that mission was kept alive as an orbital platform for space-based experiments.
    • While in that mission, the fourth stage had Li-Ion batteries, solar panels are an addition this time.
    • The latest repurposing and upgrade of the fourth stage of the PSLV rocket involves the stabilization of the orbital platform.

    From UPSC perspective, the following things are important:

    Prelims level: CAPSTONE satellite

    Mains level: Not Much

    NASA has launched CAPSTONE, a microwave oven-sized CubeSat weighing just 55 pounds (25 kg).

    What is CAPSTONE?

    • CAPSTONE, short for Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, is designed to test a unique, elliptical lunar orbit.
    • It aims to help reduce risk for future spacecraft by validating innovative navigation technologies, and by verifying the dynamics of the halo-shaped orbit.

    Its launch

    • It is heading toward an orbit intended in the future for Gateway, a Moon-orbiting outpost that is part of NASA’s Artemis program.
    • The orbit is known as a near-rectilinear halo orbit (NRHO).
    • It is significantly elongated, and is located at a precise balance point in the gravities of Earth and the Moon.
    • This offers stability for long-term missions like Gateway, NASA said on its website.

    Mission details

    • CAPSTONE will enter NRHO, where it will fly within 1,600 km of the Moon’s North Pole on its near pass and 70,000 km from the South Pole at its farthest.
    • The spacecraft will repeat the cycle every six-and-a-half days and maintain this orbit for at least six months to study dynamics.

    Typhi: A more drug-resistant Typhoid

    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: Salmonella Typhi

    Mains level: Not Much

    The bacteria causing typhoid fever is becoming increasingly resistant to some of the most important antibiotics for human health.

    What is the news?

    • The largest genome analysis of Salmonella Typhi (S. Typhi) also shows that resistant strains — almost all originating in South Asia — have spread to other countries nearly 200 times since 1990.
    • The researchers noted that typhoid fever is a global public health concern, causing 11 million infections and more than 1,00,000 deaths per year.
    • Antibiotics can be used to successfully treat typhoid fever infections, but their effectiveness is threatened by the emergence of resistant S. Typhi strains.

    What is Salmonella Typhi?

    • Salmonella Typhi (S. Typhi) are bacteria that infect the intestinal tract and the blood.
    • It is usually spread through contaminated food or water.
    • Once S. Typhi bacteria are eaten or drunk, they multiply and spread into the bloodstream.
    • The disease is referred to as typhoid fever. S. Paratyphi bacteria cause a similar, but milder illness, which comes under the same title.
    • Paratyphoid has a shorter duration, generally, than typhoid.
    • Typhi and S. Paratyphi are common in many developing countries where sewage and water treatment systems are poor.

    How does it spread?

    • Salmonella Typhi lives only in humans.
    • Persons with typhoid fever carry the bacteria in their bloodstream and intestinal tract.
    • Symptoms include prolonged high fever, fatigue, headache, nausea, abdominal pain, and constipation or diarrhoea.
    • Some patients may have a rash. Severe cases may lead to serious complications or even death.
    • Typhoid fever can be confirmed through blood testing.

  • New Species of Plants and Animals Discovered

    Four new corals recorded from Indian waters

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Corals, Coral Bleaching

    Mains level: Not Much

    Scientists have recorded four species of corals for the first time from Indian waters. These new species of azooxanthellate corals were found from the waters off the Andaman and Nicobar Islands.

    What are Azooxanthellate Corals?

    • The azooxanthellate corals are a group of corals that do not contain zooxanthellae and derive nourishment not from the sun but from capturing different forms of planktons.
    • They are deep-sea representatives with the majority of species being reported from depths between 200 metres and 1,000 metres.
    • They are also reported from shallow waters unlike zooxanthellate corals that are restricted to shallow waters.

    Which are the news species found?

    • Truncatoflabellum crassum, T. incrustatum, T. aculeatum, and T. irregulare under the family Flabellidae were previously found in Japan, the Philippines and Australian waters.
    • Only T. crassum was reported with the range of Indo-West Pacific distribution.

    Significance of the discovery

    • Most studies of hard corals in India have been concentrated on reef-building corals while much is not known about non-reef-building corals.
    • These new species enhance our knowledge about non-reef-building solitary corals.

    Back2Basics: Coral Reefs

    • Corals are marine invertebrates or animals not possessing a spine.
    • Each coral is called a polyp and thousands of such polyps live together to form a colony, which grows when polyps multiply to make copies of themselves.
    • Australia’s Great Barrier Reef is the world’s largest reef system stretching across 2,300 km.
    • It hosts 400 different types of coral, gives shelter to 1,500 species of fish and 4,000 types of mollusc.
    • Corals are of two types — hard coral and soft coral:
    1. Hard corals, also called hermatypic or ‘reef building’ corals extract calcium carbonate (also found in limestone) from the seawater to build hard, white coral exoskeletons.
    2. Soft coral polyps, however, borrow their appearance from plants, attach themselves to such skeletons and older skeletons built by their ancestors. Soft corals also add their own skeletons to the hard structure over the years and these growing multiplying structures gradually form coral reefs. They are the largest living structures on the planet.

    How do they feed themselves?

    • Corals share a symbiotic relationship with single-celled algae called zooxanthellae.
    • The algae provides the coral with food and nutrients, which they make through photosynthesis, using the sun’s light.
    • In turn, the corals give the algae a home and key nutrients.
    • The zooxanthellae also give corals their bright colour.

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

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Sao Joao Festival

    Mains level: Not Much

    As in every monsoon, Catholics in Goa will celebrate Sao Joao, the feast of St John the Baptist.

    Note: The name typically sounds like a North-Eastern festival, but it is not.

    What is Sao Joao and where is it celebrated in Goa?

    • In Goa, Catholics celebrate all the feasts of the Roman Catholic Church, which include the feast of St John the Baptist on June 24.
    • John the Baptist is the person who he had baptised Jesus Christ on the river Jordan.
    • Traditionally, there are spirited Sao Joao festivities in the villages of Cortalim in South Goa and Harmal, Baga, Siolim and Terekhol in North Goa.
    • However, over the years, pool parties and private Sao Joao parties in Goa have been a “complete package of merriment and joy” for tourists.

    Course of celebration

    • The celebrations will include revellers sporting crowns made of fruits, flowers and leaves, and the major draw of the feast is the water bodies – wells, ponds, fountains, rivers – in which the revellers take the “leap of joy”.
    • Enjoyed by children and adults alike, the festival also includes playing the traditional gumott (percussion instrument), a boat festival, servings of feni, and a place of pride for new sons-in-law.

    What does jumping into water bodies symbolise?

    • The youngsters in Goa celebrate this occasion with revelry and perform daredevil feats, by jumping into over flowing wells or rivulets.
    • The boys are found merrily jumping into the water to commemorate the leap of joy, which St John is said to have taken in the womb of his mother St Elizabeth when virgin Mary visited her.

    Summer Solstice 2022: What is it and how is it significant?

    Prelims Only | Trivia | Mains Paper 1: Geographical Features & Their Location

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Summer Solstice

    Mains level: NA

    Yesterday, June 21 was the day of the summer solstice in the northern hemisphere.

    What is Summer Solstice?

    • Solstice means “sun stands still” in Latin.
    • The longest day of 2021 for those living north of the Equator is June 21.
    • This day is characterized by a greater amount of energy received from the sun.
    • In technical terms, this day is referred to as the summer solstice, the longest day of the summer season.
    • It occurs when the sun is directly over the Tropic of Cancer, or more specifically right over 23.5-degree north latitude.

    The Southern Hemisphere receives most sunlight on December 21, 22 or 23 when the northern hemisphere has its longest nights– or the winter solstice.

    Why do we have summer solstice?

    • Since Earth rotates on its axis, the Northern Hemisphere gets more direct sunlight between March and September over the course of a day.
    • This also means people living in the Northern Hemisphere experience summer during this time.
    • The rest of the year, the Southern Hemisphere gets more sunlight.
    • During the solstice, the Earth’s axis — around which the planet spins, completing one turn each day — is tilted in a way that the North Pole is tipped towards the sun and the South Pole is away from it.

    Answer this PYQ in the comment box:

    Q.On 21st June, the Sun (CSP 2019):

     

    (a) Does not set below the horizon at the Arctic Circle

    (b) Does not set below the horizon at Antarctic Circle

    (c) Shines vertically overhead at noon on the Equator

    (d) Shines vertically overhead at the Tropic of Capricorn

     

    Post your answers here.

    Some interesting facts

    • During the June solstice compared to any other time of the year, the North Pole is tipped more directly toward the sun, and the south pole is tipped more directly away from the sun.
    • As a result, all locations north of the equator see days longer than 12 hours and all locations south see days shorter than 12 hours.
    • The sun’s path across the sky is curved—NOT a straight line on the summer solstice.
    • Based on Earth’s current orbit, the summer solstice date rotates between June 20, 21 and 22 and is not fixed since it depends on the physics of our solar system and not on human calendar.

  • BRICS Summits

    China to host BRICS Virtual Summit

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

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: BRICS Plus

    Mains level: Chinese push for expansion of BRICS

    Chinese President Xi Jinping will host a virtual summit of the leaders of the BRICS countries. PM Modi is expected to join.

    Why in news?

    • China is keen for the grouping to explore expansion and include new developing country members.
    • Under the “BRICS Plus” format, the forthcoming summit is also expected to be attended by leaders of invited emerging countries.

    What is BRICS?

    • BRICS is an acronym for the grouping of the world’s leading emerging economies, namely Brazil, Russia, India, China and South Africa.
    • The BRICS Leaders’ Summit has convened annually. It does not exist in form of an organization, but it is an annual summit between the supreme leaders of five nations.

    Its inception

    • On November 30, 2001, Jim O’Neill, a British economist who was then chairman of Goldman Sachs Asset Management, coined the term ‘BRIC’ to describe the four emerging economies of Brazil, Russia, India, and China.
    • He made a case for BRIC on the basis of econometric analyses projecting that the four economies would individually and collectively occupy far greater economic space and become among the world’s largest economies in the next 50 years or so.

    How it has formed?

    • The grouping was formalized during the first meeting of BRIC Foreign Ministers on the margins of the UNGA in New York in September 2006.
    • The first BRIC Summit took place in 2009 in the Russian Federation and focused on issues such as reform of the global financial architecture.

    Who are the members?

    • South Africa was invited to join BRIC in December 2010, after which the group adopted the acronym BRICS. South Africa subsequently attended the Third BRICS Summit in Sanya, China, in March 2011.
    • The Chairmanship of the forum is rotated annually among the members, in accordance with the acronym B-R-I-C-S.
    • The importance of BRICS is self-evident: It represents 42% of the world’s population, 30% of the land area, 24% of global GDP and 16% of international trade.
    • The five BRICS countries are also members of G-20.

    Back2Basics: BRICS Plus

    • The BRICS outreach to Africa began at the last summit hosted by South Africa, in 2013. It has picked up momentum now but African leaders want more.
    • They need big loans from the New Development Bank (NDB) for their infrastructure projects.
    • China introduced the “BRICS Plus” format at the Xiamen summit last year by inviting a few countries from different regions.
    • South Africa emulated it, arranging the attendance of top-level representation of five nations of its choice: Argentina, Jamaica, Turkey, Indonesia and Egypt.
    • The precise role of “BRICS Plus” countries will take time to evolve but an immediate benefit is the immense opportunities it provides for networking among leaders.

    Explained: Occurrence of Lightning

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

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Lightening and Thunderstorms

    Mains level: Disaster management

    At least 70 people died in lightning strikes across Uttar Pradesh, Madhya Pradesh and Rajasthan.

    What is lightning?

    • Scientifically, lightning is a rapid and massive discharge of electricity in the atmosphere some of which is directed towards earth.
    • The discharges are generated in giant moisture-bearing clouds that are 10-12 km tall.
    • The base of these clouds typically lie within 1-2 km of the Earth’s surface, while the top is 12-13 km away.
    • Temperatures in the top of these clouds are in the range of –35° to –45°C.

    Its formation

    • As water vapour moves upward in the cloud, the falling temperature causes it to condense.
    • As they move to temperatures below 0°C, the water droplets change into small ice crystals.
    • They continue to move up, gathering mass until they are so heavy that they start to fall to Earth.
    • This leads to a system in which, simultaneously, smaller ice crystals are moving up and bigger crystals are coming down.
    • Collisions follow and trigger the release of electrons, a process that is very similar to the generation of sparks of electricity.
    • As the moving free electrons cause more collisions and more electrons, a chain reaction ensues.
    • This process results in a situation in which the top layer of the cloud gets positively charged, while the middle layer is negatively charged.
    • The electrical potential difference between the two layers is huge, of the order of a billion to 10 billion volts.
    • In very little time, a massive current, of the order of 100,000 to a million amperes, starts to flow between the layers.

    Types of lightning

    • Broadly, there are three forms of lightning:
    1. Inter-cloud
    2. Intra-cloud
    3. Cloud-to-ground
    • It is the cloud-to-ground form of lightning that kills humans, as well as animals and livestock, and can substantially damage property.
    • While the Earth is a good conductor of electricity, it is electrically neutral.
    • However, in comparison to the middle layer of the cloud, it becomes positively charged.
    • As a result, about 15%-20% of the current gets directed towards the Earth as well.
    • It is this flow of current that results in damage to life and property on Earth.

    How intensely does it strike?

    • A typical lightning flash is about 300 million volts and 30,000 amps.
    • To put it in perspective, household current is 120 volts and 15 amps.
    • A flash of lightning is enough to light a 100-watt incandescent bulb for about three months.

    Why does lightning kill so many people in India?

    • The reason for the high number of deaths is due to people being caught unawares and more than 70% of fatalities happened due to people standing under isolated tall trees.
    • About 25 per cent of the people were struck in the open.
    • Also, lightning is the direct promulgation of climate change extremities.

    Mitigating lightning incidents

    • Lightning is not classified as a natural disaster in India.
    • But recent efforts have resulted in the setting up of an early warning system that is already saving many lives.
    • More than 96% of lightning deaths happen in rural areas.
    • As such, most of the mitigation and public awareness programmes need to focus on these communities.
    • Lightning protection devices are fairly unsophisticated and low-cost. Yet, their deployment in the rural areas, as of now, is extremely low.
    • States are being encouraged to prepare and implement lightning action plans, on the lines of heat action plans.
    • An international centre for excellence on lightning research to boost detection and early warning systems is also in the process of being set up.
