INS Arihant
Context: India’s Nuclear Submarine INS Arihant has successfully launched Submarine Launched Ballistic Missile (SLBM).
More on the News:
- The launch of the SLBM by INS Arihant is significant to prove crew competency and validate India’s nuclear deterrence capability.
- A robust, survivable and assured retaliatory capability will uphold India’s policy to have ‘Credible Minimum Deterrence’.
INS Arihant:
- INS Arihant is India’s nuclear-powered ballistic missile capable submarine and was commissioned in 2016.
- It was the first of the planned five in the class of submarines designed and constructed as a part of Advanced Technology Vessel (ATV) project of Indian Navy.
- Technology: The Arihant class submarines are reported to be based on the Akula-class submarine of Russian Navy. It is powered by an 83 MW pressurized light-water reactor with enriched uranium fuel.
- Significance: The capability of submarines being able to launch nuclear weapons has great strategic importance in the context of achieving a nuclear triad.
Submarine Launched Ballistic Missiles (SLBMs):
- It is a family of indigenously developed Submarine Missiles. They are also referred to as K-family missiles, codenamed after Dr APJ Abdul Kalam.
- Under SLBM, missiles of various ranges have been developed including K-15 also called Sagarika. It has a range of at least 750 km.
- India has also developed and tested the K-4 missiles from the same family, having a range of 3,500 km.

Paddy Straw Pelletisation And Torrefaction Scheme
Context: The Union Ministry of Environment has announced a one-time only scheme to incentivize industrialists to set up paddy straw pelletisation and torrefaction plants.
About the Scheme:
- New units would be eligible for government funding in the form of capital to set up such plants.
- The Union government will fund pelletisation plants to a maximum of Rs 70 lakh subject to capacity.
- The cost of setting up a torrefaction plant is higher and under the scheme, is eligible for a maximum funding of Rs 1.4 crore.
Pelletisation and Torrefaction:
- Pelletisation is a process of molding biomass into dense pellets.
- Torrefaction is a process in which a biomass is heated in oxygen-deficient environment to completely remove moisture.
- The product of torrefaction is costlier as its energy content is much higher and theoretically substitutes for more coal in a power plant.
- Significance: These processes can save coal as well as reduce carbon emissions, which would have been emitted in case the straw were burnt in the fields.
Stubble Burning:
- Stubble burning is the practice of intentionally setting fire to the straw stubble that remains after harvesting of crops such as paddy.
- The practice is prevalent in Punjab, Haryana, Rajasthan and Western Uttar Pradesh, which has led to air pollution in Delhi-NCR region.
Rythu Bharosa Kendras
Context: An Ethiopian delegation visited Andhra Pradesh to study the Rythu Bharosa Kendras (RBKs) and to understand their operational know-how.
What are Rythu Bharosa Kendras (RBKs)?
- They are first-of-its-kind seeds-to-sales, single-window service centres for farmers set up by the state government of Andhra Pradesh.
- These multi-functional kiosks with digital Aadhar authentication equipment act as a one-stop solution for all requirements and grievances of farmers in the state.
Services Provided by RBKs:
- These centres sell pre-tested quality seeds, certified fertilizers and livestock feed.
- They also provide farm equipment and enable farmers to sell their produce at the prevailing minimum support price (MSP) via supporting systems of e-cropping, geo-tagging and CM App.
- They provide services like soil testing and consultancy regarding what crops to sow and quality and type of fertilizer to be used.
- They facilitate interaction between farmers, agriculture scientists, and agriculture extension officers right at the village level.
Significance:
- This has helped farmers change their cropping patterns and increase profits.
- RBKs are responsible for the elimination of unproductive seeds and uncertified and dangerous fertilizers from the market. This has minimized crop damage and failures significantly.
Recognition:
- The RBKs were recently nominated for UN Food and Agriculture Organization’s Champion Awards (CCA), which recognizes contributions of governments in boosting food security.
Next-Gen Launch Vehicle (NGLV)
Context: The Indian Space Research Organization (ISRO) is developing a Next-Gen Launch Vehicle (NGLV) to replace operational systems like the Polar Satellite Launch Vehicle (PSLV).
What are launch vehicles?
- Launchers or Launch Vehicles are used to carry spacecraft to space.
- India has two operational launch vehicles: Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV).
What is the New-Gen Launch Vehicle (NGLV)?
- About: It is a cost-efficient, three-stage to orbit, reusable heavy-lift vehicle with a payload capability of ten tonnes to Geostationary Transfer Orbit (GTO).
- Features:
- It will feature semi-cryogenic propulsion (refined kerosene as fuel with liquid oxygen (LOX) as oxidizer) for the booster stages, which is cheaper and efficient.
- Its design will be simple and robust which allows bulk manufacturing, modularity in systems, sub-systems and stages and minimal turnaround time.
- Uses: Potential uses will be in the areas of launching communication satellites, deep space missions, future human spaceflight and cargo missions.
