Start-up Agnikul launches world’s first rocket with fully 3D-printed engine
Agnikul Cosmos Private Ltd., based in Chennai, successfully launched the world’s first rocket, Agnibaan Sub Orbital Technology Demonstrator (SOrTeD).
Significance of Agnibaan SOrTeD:
- Agnibaan SOrTeD marks India’s maiden launch from a private launchpad named ‘Dhanush,’ established by Agnikul.
- It is distinguished as India’s first semi-cryogenic engine-powered rocket launch and features the world’s premier single-piece 3D-printed engine, developed domestically.
Mission Objectives:
- The primary objective of this mission is to conduct a test flight, showcasing internally developed technologies, collecting vital flight data, and validating system functionality for Agnikul’s orbital launch vehicle.
Tamil Nadu’s Contribution:
- The Tamil Nadu Industrial Development Corporation (TIDCO) lauded this accomplishment, highlighting Tamil Nadu’s significant stride toward prominence in the space sector.
Comparison between Cryogenic and Semi-Cryogenic Engines:
Cryogenic Engines:
Utilize cryogenics to store fuel and oxidizer as liquids, exploiting materials’ properties at extremely low temperatures.
Liquid hydrogen and liquid oxygen are commonly used as propellants.
Challenges include the high cost and complexity associated with storing and handling liquid hydrogen.
Semi-Cryogenic Engines:
Employ refined kerosene instead of liquid hydrogen, with liquid oxygen serving as the oxidizer.
Refined kerosene is lighter and can be stored at ambient temperatures, offering advantages in affordability, simplicity, and environmental impact.
Advantages of Semi-Cryogenic Engines:
Weight and Storage:
- Refined kerosene’s lighter weight and ease of storage at normal temperatures enhance rocket efficiency and payload capacity.
Thrust and Space Efficiency:
The combination of kerosene and liquid oxygen yields increased thrust and allows for greater propellant storage within the rocket’s fuel compartment.
- Environmental and Economic Benefits: Semi-cryogenic engines are environmentally friendly, cost-effective, and deliver greater power compared to cryogenic counterparts.
- Payload Capacity: Enhanced propulsion capabilities enable semi-cryogenic engines to carry heavier payloads to higher altitudes, facilitating increased payload capacity.
- Fuel Efficiency: Reduction in fuel weight, particularly by 500kg, allows for greater payload capacity and improved fuel efficiency.
The tobacco epidemic in India
Tobacco Usage Facts:
- Global Impact: Tobacco stands as the foremost preventable cause of disease and mortality worldwide, contributing to a spectrum of illnesses affecting both consumers and growers.
- High Consumption Rates: Following China, India ranks second globally in terms of tobacco consumers, with an estimated nearly 26 crores individuals reported in 2016-2017.
- E-cigarette Usage Trends: An online survey involving 840 adults revealed that 23% acknowledged using e-cigarettes, with 8% reporting daily usage.
- Environmental Impact: Tobacco cultivation, being highly erosive, rapidly depletes soil nutrients, necessitating increased fertilizer use, which exacerbates soil degradation.
The tobacco industry generates approximately 1.7 lakh tonnes of waste annually in India.
Awareness and Control Initiatives:
- WHO Framework Convention on Tobacco Control (FCTC): India is among 168 signatories of the WHO’s FCTC, launched in 2005, aimed at global tobacco reduction through the formulation of demand and supply reduction strategies.
- Legislative Measures: India has enacted legislation governing tobacco sales since 1975, with amendments introduced in 2003.
RBI’s income rises 17% to ₹2.75 lakh cr., spending falls 56%
Annual Report Highlights:
- Income Increase: The Reserve Bank of India (RBI) reported a notable 17% surge in income for FY24, reaching ₹2,75,572.32 crore.
- Expenditure Reduction: Expenditure witnessed a significant decline of 56.3%, plummeting to ₹64,694.33 crore from ₹1,48,037.04 crore in FY23, according to the RBI’s annual report.
- Surplus Growth: The substantial decrease in spending enabled the RBI to conclude the year with a transferable surplus of ₹2,10,873.99 crore, contrasting with ₹87,416.22 crore in the preceding year.
- Revenue Sources: Notable revenue contributions stemmed from foreign exchange transactions, totaling ₹83,615.86 crore, while interest income from foreign securities rose to ₹65,327.93 crore.
Factors Identified:
- Asset Side Growth: The augmented asset side was attributed to elevations in foreign investments, gold holdings, and loans and advances by 13.9%, 18.26%, and 30.05%, respectively.
- Liabilities Expansion: Conversely, liabilities expanded due to escalations in notes issued, deposits, and other liabilities by 3.88%, 27%, and 92.57%, respectively.
- Composition Breakdown: Domestic assets constituted 23.31%, while foreign currency assets, gold reserves, and loans and advances to financial institutions outside India constituted 76.69%.
Future Outlook for the Indian Economy:
- Positive Outlook: The RBI remains optimistic about the Indian economy, emphasizing the strength of the financial and corporate sectors alongside a resilient external sector.
- Inflation Trends: With headline inflation easing towards the target, the RBI anticipates a revival in consumption demand, particularly in rural areas.
- Resilience from External Sector: The robust external sector, coupled with substantial buffers in the form of foreign exchange reserves, is expected to shield domestic economic activity from global shocks.
