  • ISRO to attempt 200th consecutively successful launch of RH-200 sounding rocket

    rh-200

    The Indian Space Research Organisation (ISRO) has attempted the 200th consecutively successful launch of the Rohini RH-200 sounding rocket from Thumba.

    RH-200 (Rohini )

    • 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.

  • Limiting the Anti-Biotic Pollution and Anti-microbial resistance (AMR)

    Anti-microbial

    Context

    • Almost half, or 43 per cent, of the world’s rivers are contaminated with active pharmaceutical ingredients in concentrations that can have disastrous ramifications on health. The industry must prioritize wastewater management and process controls to limit antibiotic pollution and Anti-microbial resistance (AMR). 18-22 November is observed as World Antimicrobial awareness week.

    What is Anti-microbial resistance (AMR)?

    • Antimicrobial resistance (AMR or AR) is the ability of a microbe to resist the effects of medication that once could successfully treat the microbe
    • Antibiotic resistance occurs naturally, but misuse of antibiotics in humans and animals is accelerating the process.
    • A growing number of infections – such as pneumonia, tuberculosis, gonorrhoea, and salmonellosis – are becoming harder to treat as the antibiotics used to treat them become less effective.
    • It leads to higher medical costs, prolonged hospital stays, and increased mortality.

    Anti-microbial

    Importance of Pharma Industry

    • Important sector of economy: The recently adopted Glasgow Climate Pact has called upon countries to facilitate the adoption of greener technologies to phase out the use of fossil fuels. The development and deployment of such technologies is also critical for the pharmaceutical sector that has formed the backbone of the growth of many economies including India.
    • Improving the health outcomes: The Pharma sector plays a fundamental role in improving health outcomes through the invention of life-saving products.
    • 20% of global supply of medication: Pivoting to sustainable waste management and process-control practices assumes acute significance in the Indian context. India already accounts for 20 per cent of the global supply of medication, making it the largest supplier of generic medicines worldwide.

    Anti-microbial

    Anti-biotic Pollution and Anti-microbial resistance (AMR)

    • Pharmaceutical pollution in the country: Recently, widescale pharmaceutical pollution has been reported across the country, particularly in pharmaceutical hubs like Himachal Pradesh, Andhra Pradesh, and Telangana.
    • Untreated waste release into rivers: The release of untreated effluents into the soil and water bodies add to the pollution of the environment during the manufacturing of various pharmaceuticals, including antibiotics. Further, untreated antibiotic residues also accelerate the build-up of antimicrobial resistance (AMR).
    • High emission intensity: Pharma sectors emission intensity is 55 per cent more than the automotive sector.
    • AMR is public health threat: AMR is often dubbed as one of the top 10 public health threats facing humanity. It occurs when disease-causing pathogens develop a resistance against the pharmaceuticals that could have neutralized them. In 2019, AMR accounted for more than half a million deaths in the European region and about five million globally.
    • Accumulation of AMR in ecosystem: The build-up of AMR can happen due to several factors across the human, animal, and environmental ecosystems.

    Government policies to prevent Anti-biotic pollution in India

    • National Action Plan on AMR (NAP-AMR): India’s production capacity is all set to expand further with the government’s recent impetus on the domestic production of pharmaceuticals. Against this background, the country’s National Action Plan on AMR (NAP-AMR) called for limiting pharmaceutical pollution.
    • Surveillance of residues discharged: Strategic Pillars 2 and 3 under the NAP-AMR focused on developing frameworks for the surveillance of residues discharged in the environment and developing a plan to reduce the environmental impact on AMR, respectively. However, this policy impetus is yet to translate into on-ground implementation.
    • Benefits to manufacturers with greener practices: The government can take a cue from countries like the United Kingdom, Norway, Sweden and Germany, among others, which have policies in place that provide benefits to manufacturers with greener practices.

    How pharmaceutical industry can improve its waste management?

    • Use of innovative technologies: Adopting innovative technology and self-regulation can help the industry reduce its carbon footprint and minimize its environmental impact.
    • State-of-art API technology: Centrient Pharmaceuticals Netherlands BV’s plant at Toansa, Punjab, where the adoption of state-of-art API technology led to a 60-62 per cent reduction in the plant’s carbon footprint.
    • Regulating the discharge: The AMR Industry Alliance (AMRIA) has developed the Predicted No-Effect Concentrations (PNEC) criteria further to facilitate the industry in regulating its discharge of effluents.
    • Strict compliance of guidelines: The compliance to PNEC value for Centrist’s oral API product line and supply chain has helped the company reduce the environmental impact of manufacturing.

    Conclusion

    • The containment of AMR in India is crucial for realizing several policy goals, including the United Nations Sustainable Development Goals. While collective action is needed from various stakeholders, the domestic pharmaceutical industry should also take the lead, especially in limiting antibiotic pollution.

    Mains Question

    Q. Explain the linkages between Anti-biotic pollution and anti-microbial resistance (AMR). How government and pharma industry join the hands to reduce the anti-biotic pollution?

  • Hwasong-17: North Korea’s new ‘monster missile’

    hwasong

    North Korea said it test-fired its massive new Hwasong-17 intercontinental ballistic missile (ICBM).

    Hwasong-17  

    • The Hwasong-17 is nuclear-armed North Korea’s biggest missile yet, and is the largest road-mobile, liquid-fuelled ICBM in the world.
    • Its diameter is estimated to be between 2.4 and 2.5 metres, and its total mass, when fully fuelled, is likely somewhere between 80,000 and 110,000 kg.
    • Unlike North Korea’s earlier ICBMs, the Hwasong-17 is launched directly from a transporter, erector, and launcher (TEL) vehicle with 11 axles, photos by state media showed.

    How far can it fly?

    • The missile launched on Friday flew nearly 1,000 km (621 miles) for about 69 minutes and reached a maximum altitude of 6,041 km.
    • The weapon could travel as far as 15,000 km (9,320 miles), enough to reach the continental United States.

    What is North Korea trying to demonstrate with the missile launches?

    • North Korea is wary of joint drills between the US and South Korea and believes them to be a rehearsal for invasion and proof of hostile policies.
    • Notably, Pyongyang’s record launches this year began even before military exercises between the allies, one also involving Japan.
    • While it says it is responding to the “provocative” drills, some analysts believe that Kim Jong-un must be setting the stage for something bigger— the resumption of nuclear testing after five years.
    • Pyongyang may also be showcasing its pre-emptive abilities in response to South Korea’s own pre-emptive “kill chain” strategy.

    Failure of diplomacy

    • North Korea pulled out of the Nuclear Non-proliferation Treaty (NPT) in January 2003 and has conducted six nuclear tests so far since 2006.
    • Diplomatic talks have been starting and halting over the past two decades.
    • The Six-Party Talks involving South and North Korea, China, Japan, Russia, and the United States, started in 2003, have since stalled with changing geopolitical dynamics.
    • Former U.S. President Donald Trump met with Kim Jong-un thrice between 2018 and 2019 but talks broke down and resulted in more sanctions from the West and increased testing by Pyongyang.
    • The Joe Biden administration did make attempts to restart talks, and North Korea has not seemed keen either.

  • 2022 AP7: the Planet Killer Asteroid

    asteroid

    A team of astronomers have spotted a massive near-Earth asteroid called 2022 AP7 believed to be the largest planet killer-sized asteroid to be spotted in nearly a decade.

    2022 AP7 Asteroid

    • An asteroid is a relatively small chunk of rocky minerals that orbits the Sun, often described as a minor planet.
    • 2022 AP7 is among the three asteroids hiding in the glare of the Sun.
    • It is 1.5-kilometre-wide and has an orbit that may someday put it on a collision course with our planet.
    • At present, researchers have little information about the asteroid, including further details on its possible trajectory and its composition.
    • It was found using the Dark Energy Camera at the Cerro Tololo Inter-American Observatory in Chile.

    What about the other two?

    • The two — 2021 LJ4 and 2021 PH27 — have orbits that are safely constrained inside the limits of Earth’s orbit.
    • At less than a kilometer in diameter, 2021 LJ4 is the smallest in size.
    • The asteroid, 2021 PH27, is the closest known asteroid to the Sun.
    • Due to this, its surface gets hot enough to melt lead.

    Is there an immediate threat to Earth?

    • At present, the asteroid only crosses the Earth’s orbit while it is on the opposite side of the Sun i.e., when the Sun comes between the Earth and the asteroid.
    • This will continue for several centuries as it takes the asteroid about five years to orbit the sun.
    • If impacted, Earth’s atmosphere would be inundated with dust and pollutants for years, preventing sunlight from entering.

  • What are Coronal Holes?

    coronal

    Recently, NASA tweeted an image of the sun seemingly ‘smiling’. NASA explained that the patches are called coronal holes, which can be seen in ultraviolet light but are typically invisible to our eyes.

    What are Coronal Holes?

    • Coronal holes are regions on the sun’s surface from where fast solar wind gushes out into space.
    • Because they contain little solar material, they have lower temperatures and thus appear much darker than their surroundings.
    • Here, the magnetic field is open to interplanetary space, sending solar material out in a high-speed stream of solar wind.
    • They can last between a few weeks to months.
    • The holes are not a unique phenomenon, appearing throughout the sun’s approximately 11-year solar cycle.
    • They can last much longer during solar minimum – a period of time when activity on the Sun is substantially diminished.

    How are they formed?

    • It is unclear what causes coronal holes.
    • They correlate to areas on the sun where magnetic fields soar up and away, without looping back down to the surface as they do elsewhere.

    What do they tell us?

    • These ‘coronal holes’ are important to understanding the space environment around the earth through which our technology and astronauts travel.
    • In 2016 coronal holes covering “six-eight per cent of the total solar surface” were spotted.
    • Scientists study these fast solar wind streams because they sometimes interact with earth’s magnetic field, creating what’s called a geomagnetic storm.
    • These storms can expose satellites to radiation and interfere with communications signals.

    Back2Basics: Geomagnetic Storms

    coronal

    • Geomagnetic storms relate to earth’s magnetosphere – the space around a planet that is influenced by its magnetic field.
    • When a high-speed solar stream arrives at the earth, in certain circumstances it can allow energetic solar wind particles to hit the atmosphere over the poles.
    • Such geomagnetic storms cause a major disturbance of the magnetosphere as there is a very efficient exchange of energy from the solar wind into the space environment surrounding earth.
    • In cases of a strong solar wind reaching the earth, the resulting geomagnetic storm can cause changes in the ionosphere, part of the earth’s upper atmosphere.
    • Radio and GPS signals travel through this layer of the atmosphere, and so communications can get disrupted.

  • Centre restricts use of common weedicide Glyphosate

    Glyphosate

    The Union Ministry of Agriculture and Farmers Welfare has restricted the use of glyphosate, a widely used herbicide, citing health hazards for humans and animals.

    What is Glyphosate?

    • Glyphosate is an herbicide. It is applied to the leaves of plants to kill both broadleaf plants and grasses.
    • The sodium salt form of glyphosate is used to regulate plant growth and ripen specific crops.
    • Glyphosate is one of the most widely used herbicide.
    • In India, glyphosate has been approved for use only in tea plantations and non-plantation areas accompanying the tea crop.
    • Use of the substance anywhere else is illegal.

    How does glyphosate work?

    • Glyphosate is a non-selective herbicide, meaning it will kill most plants.
    • It prevents the plants from making certain proteins that are needed for plant growth.
    • Glyphosate stops a specific enzyme pathway, the shikimic acid
    • The shikimic acid pathway is necessary for plants and some microorganisms.

    What is the recent ban?

    • Only authorized Pest Control Operators are allowed to use it.
    • Earlier, state governments of Maharashtra, Telangana, Punjab and Andhra Pradesh have tried similar steps but failed.
    • The ban notification was based on a 2019 report by the Government of Kerala on prohibiting the distribution, sale and use of glyphosate and its derivatives.

    Is it banned elsewhere?

    • Some 35 countries have banned or restricted the use of glyphosate.
    • These include Sri Lanka, Netherlands, France, Colombia, Canada, Israel and Argentina.

    Hazards of Glyphosate

    • Health impacts of glyphosate range from cancer, and reproductive and developmental toxicity to neurotoxicity and immune toxicity.
    • Symptoms include irritation, swelling, burning of the skin, oral and nasal discomfort, unpleasant taste and blurred vision.

  • Green Signal to GM Mustard

    MustardContext

    • The recent clearance by the government for the release of GM Mustard Hybrid DMH 11 based on the recommendations of GEAC under the Ministry of Environment, Forests and Climate Change is a bold decision in the best interest of our farmers and the nation.

    What are Genetically modified organisms (GMO)

    • Changes in genetic material: GMOs can be defined as organisms (i.e., plants, animals or microorganisms) in which the genetic material (DNA) has been altered in a way that does not occur naturally by mating and/or natural recombination
    • Transfers of genes: It allows selected individual genes to be transferred from one organism into another, also between nonrelated species.
    • GM foods: Foods produced from or using GM organisms are often referred to as GM foods
    • GM Mustard: GM mustard crop was introduced, which was later withdrawn. There is a raging debate going on advantages and disadvantages of GMOs. For a long time, further study was requested by farmers, environmentalist on GMO crops.

    MustardAdvantages of GM mustard?

    • Benefits to producers and consumers: GM foods are developed and marketed because there is some perceived advantage either to the producer or consumer of these foods. This is meant to translate into a product with a lower price, greater benefit (in terms of durability or nutritional value) or both. Initially GM seed developers wanted their products to be accepted by producers and have concentrated on innovations that bring direct benefit to farmers (and food industry generally)
    • Improves crop protection: One of the objectives for developing plants based on GM organisms is to improve crop protection.
    • Insect Resistance: Some GMO foods have been modified to make them more resistant to insects and other pests. This means the amount of pesticide chemicals used on the plants are reduced, so their exposure to dangerous pesticides is also reduced
    • Develops stronger Crop: Another benefit that GM technology is believed to bring about is that crops can be engineered to withstand weather extremes and fluctuations, this means that there will be good quality and sufficient yields even under a poor or severe weather condition
    • Provides Environment Protection: GM crops often requires less time, tools and chemicals, and may help with reducing greenhouse gas emissions, soil erosion and environmental pollution
    • More Nutritious Foods: According to the UN Food and Agricultural Organization (FAO), some GM foods have been engineered to become more nutritious in terms of vitamin or mineral content.
    • More economic benefits: Larger production leading to increased farm income, reduced poverty, low food prices and thus reduced hunger and malnutrition. Besides new food products are also included, diversifying food varieties

    What is the risk associated with GMO?

    • Contamination of genes: GMOs contaminate forever. GMOs cross pollinate and their seeds can travel far and wide.
    • Irreversible changes in gene pool: It is impossible to fully clean up our contaminated gene pool.
    • More herbicides in our food: Genetic engineering allows plants to survive high doses of weed killers, resulting in higher herbicide residues in our food.
    • Super weeds and super bugs: GMO crops are creating ‘super weeds’ and ‘super bugs,’ which can only be killed with more toxic poisons.

    MustardWhy there was necessity to grant approval for GM Mustard?

    • To meet our current challenges: Over-exploitation of natural resources (soil, water, biodiversity), declining factor productivity, urgency to achieve sustainable development goals, especially ending poverty and hunger, and addressing timely the adverse effects of climate change the best option is scientific innovations and their scaling.
    • The adoption of GM food crops is in our broader national interest: Genetically modified maize, soybean, cotton, tomato and canola are grown across the world and the area currently under GM crops is about 200 m ha. Besides India, these have been grown for many years in the US, Brazil, Argentina, Canada, Australia, Philippines, Pakistan, Bangladesh, and China.
    • To meet the existing deficit in edible oils: India is currently importing around 13 million tonnes at a cost of Rs 1.17 lakh crore to the exchequer. Interestingly, of this, 2.0-2.5 mt soybean oil and 1.0-1.5 mt canola oil is already GM. Hence, we are consuming GM oil already, besides, the 1.5 mt of GM cotton oil produced domestically.
    • Associated health benefits: It is scientifically proven that the consumption of refined oil does not allow any protein to enter the human system. Thus, the consumption of GM oil is completely safe from a health point of view.
    • High yields to farmers: A major concern of our farmers is that yields of mustard are low and have stagnated for a long time at around 1,260 kg/ha, much lower than the global average of 2,000 kg/ha. Yields of canola in Canada, China and Australia are almost three times higher than in India since they use GM hybrid technology. Mustard is a very important oilseed crop, grown in 6.0 -7.0 million hectares, mostly in Rajasthan, Haryana, Punjab and Madhya Pradesh. Thus, the government’s decision to allow the production of GM Mustard hybrids will go a long way in increasing our yields, while reducing the use of pesticides.

    MustardWhat else needs to be done?

    • Providing enabling environment: The Department of Agriculture (DoA) and ICAR need to move forward fast and provide an enabling environment to test the available seed of Hybrid DMH 11 in the current rabi season.
    • Encourage public-private partnership: This needs to happen on several farmers’ fields in the mustard belt. It must also encourage public-private partnerships to produce quality seeds to cover more area next year.
    • Encouraging further innovation: Also, scientists at ICAR institutes must be encouraged to develop new GM Mustard hybrids on a mission mode. Allowing the production of GM Soybean and GM Maize going forward will also be a positive step, increasing both the productivity and profitability of these crops and doubling farmers’ income.

    Conclusion

    • The decision to remove the unscientific ban on GM crops reflects the determination of the government to move towards Atmanirbhar Bharat. It also meets the aspirations of our scientific community and farmers can derive the benefits of innovative technology.

  • GEAC gives its nod for commercial cultivation of GM mustard yet again

    mustard

    The Genetic Engineering Appraisal Committee (GEAC) has yet again cleared the proposal for commercial cultivation of genetically modified (GM) mustard.

    What exactly is GM (Hybridized) Mustard?

    • Hybridization involves crossing two genetically dissimilar plant varieties that can even be from the same species.
    • The first-generation (F1) offspring from such crosses tend to have higher yields than what either parent can individually give.
    • Such hybridization isn’t easy in mustard, as its flowers have both female (pistil) and male (stamen) reproductive organs, making the plants largely self-pollinating.
    • Since the eggs of one plant cannot be fertilised by the pollen grains from another, it limits the scope for developing hybrids.

    How has hybridisation been achieved in mustard?

    • This has been done by genetic modification (GM).
    • Scientists at Delhi University’s Centre for Genetic Manipulation of Crop Plants (CGMCP) have developed the hybrid mustard DMH-11.
    • It contains two alien genes isolated from a soil bacterium called Bacillus amyloliquefaciens.
    • The first gene (‘barnase’) codes for a protein that impairs pollen production and renders the plant into which it is incorporated male-sterile.
    • This plant is then crossed with a fertile parental line containing, in turn, the second ‘barstar’ gene that blocks the action of the barnase gene.
    • The resultant F1 progeny is both high-yielding and also capable of producing seed/ grain, thanks to the barstar gene in the second fertile line.

    How did researchers achieve this?

    • The CGMCP scientists have deployed the barnase-barstar GM technology to create what they say is a robust and viable hybridisation system in mustard.
    • This system was used to develop DMH-11 by crossing a popular Indian mustard variety ‘Varuna’ (the barnase line) with an East European ‘Early Heera-2’ mutant (barstar).
    • DMH-11 is claimed to have shown an average 28% yield increase over Varuna in contained field trials carried out by the Indian Council of Agricultural Research (ICAR).

    What has GEAC now done?

    • GEAC has recommended the environmental release of DMH-11 for its seed production and testing prior to commercial release.
    • In other words, it has given the green signal for commercial cultivation by farmers, with production of seed material being the first step.
    • This move was earlier vetoed in 2016 by Environment Ministry.

    Why did it take so long for GEAC to clear?

    • There has been opposition to GM crops in general, from assorted green groups.
    • Major concern is the presence of a third ‘bar’ gene, which makes GM mustard plants tolerant to the spraying of glufosinate ammonium, a chemical used for killing weeds.
    • This, the opponents allege will cause displacement of manual labour engaged in weeding by promoting use of chemical herbicides.
    • Another concern is over GM mustard threatening or undermining the population of honey bees.
    • Mustard flowers are a source of nectar for honey bees and many other pollinator insects.
