ISRO Launch Imbalance
Context: Somanath, Chairman of ISRO, highlighted that ISRO’s launch vehicle capability currently exceeds demand by three times.
Reason for Demand of Launch Vehicles
- Satellites have a defined mission life and require replacement over time, driving ongoing demand for launch vehicles.
- Advances in technology, such as reusable rocket stages, are reducing costs and enhancing the sustainability of launch operations.
Shift to Demand-Driven Model
- Previous Model: Historically, ISRO followed a supply-driven model, creating and launching satellites before securing specific demand.
- Current Model: Post-2019-2020 reforms, ISRO shifted to a demand-driven approach, where satellites are built and launched based on pre-existing demand.
Current Status Of ISRO Capability
- Launch Vehicles: India operates four primary launch vehicles:
- Small Satellite Launch Vehicle (SSLV)
- Polar Satellite Launch Vehicle (PSLV)
- Geosynchronous Satellite Launch Vehicle (GSLV)
- Launch Vehicle Mark-III (LVM-3)
- These vehicles can launch payloads up to four tonnes to geosynchronous orbit.
Satellite Operations:
- India’s satellite fleet serves various purposes including communications, remote sensing, navigation, meteorology, disaster management, and scientific missions.
- Key missions requiring launch vehicles include Chandrayaan 3 and Aditya L1.
- Upgrades and New Developments:
- LVM-3 is slated for an upgrade with a semi-cryogenic engine to increase its payload capacity to six tonnes.
- The proposed Next Generation Launch Vehicle (NGLV or Project Soorya) aims to carry 10 tonnes to geostationary transfer orbit (GTO).
Challenges in India’s Space Sector
- Awareness: There is a significant challenge in creating awareness and demand for space-based services among potential users such as businesses, government entities, and the general public.
- Technological Limitations: Current Indian launch vehicles like the LVM-3 are not capable of carrying heavy payloads compared to international counterparts such as China’s Long March 5.
- Regulatory and Policy Framework: Existing policies may not fully support the rapid growth or involvement of the private sector in the space industry.
- Dependency on Foreign Launch Services: For heavier satellites, ISRO still relies on foreign launch vehicles, which can be costly and reduce India’s autonomy in space launches.
- Example: For payloads exceeding 4 tonnes, ISRO relies on foreign launch vehicles like Europe’s Ariane V and SpaceX’s Falcon 9.
Way Forward
- Educating Customers: There’s a need to educate potential customers about the benefits of satellite services to generate demand.
- Example: The need for space-based internet services where demand must be generated before satellite constellations are launched to provide the service.
- Government Transition: The long-term strategy involves the government reducing its direct involvement in the launch business, instead supporting private companies by becoming a stable customer.
- Implement regulatory reforms to ease the participation of private entities in the space sector, including simplifying licensing procedures for satellite and launch operations.
- Technological Advancements: Accelerate the development of next-generation launch vehicles like the NGLV (Project Soorya) with enhanced payload capacities.
- Creating an Ecosystem for Space Technology: Build a supportive ecosystem that includes academia, industry, and government to foster innovation and application development.
The Toll That Extreme Heat Takes On Women
Context: Women are disproportionately harmed by extreme heat in recent periods of heatwave.
Reasons
- Living Conditions: Women in informal urban settlements, like slums, live in conditions that exacerbate heat effects. Homes made of heat-trapping materials like tin, asbestos, and plastic become extremely hot.
- Work Environment: Women often work in poorly ventilated areas, particularly in kitchens, which face intense temperatures that affect their productivity and health.
Productivity and Opportunity Costs
- Extended Work Hours: Heat stress causes women to work longer hours to complete unpaid domestic tasks.
- Productivity Loss: According to Arsht-Rock’s ‘Scorching Divide’ report, heatwaves extend care-related work by 90 minutes daily in India.
- Unpaid Labour: Women spend 2.5 times more minutes per day on unpaid labour than men, with two-thirds of their productivity loss from heat stress occurring in unpaid labour domains (National Statistical Office, 2019).
Conditions for Female Informal Labourers
- Vulnerable Work Settings: Women working as street vendors, domestic helpers, construction workers, and sanitation workers face severe weather conditions.
- Lack of Cooling Resources: Many live without adequate cooling facilities, exacerbating the heat’s impact.
- Natural Cooling Shortages: Urban areas are losing green spaces, which traditionally help mitigate heat.
Rural Challenges
- Routine Hardships: Women in rural areas start their days cooking over biomass stoves, contributing to significant health risks.
- Unsafe Working Conditions: Working inside with heat-conductive roofing or outdoors in fields places them at risk of heat-related illnesses.
- Impact on Agriculture: Heatwaves also negatively affect crop yields, influencing food security for rural families.
Health Impacts
- Heat-Related Illnesses: Women face a higher incidence of heat cramps, heat stroke, and hyperthermia due to physiological differences, such as body fat and water content.
- Reproductive Health Risks: Heat stress is linked to increased rates of preterm delivery, miscarriage, and stillbirth, which is alarming given India’s high maternal mortality rates.
Need for Resilience and Adaptation
- Policy Recommendations:
- Urban Planning: Implement climate-friendly urban designs that consider temperature reductions.
- Cooling Technologies: Develop and distribute sustainable cooling solutions.
- Care Work Division: Ensure a fairer distribution of domestic tasks.
- Essential Services: Improve public access to services that aid in heat mitigation.
Stealth Frigates
Context: Stealth frigates incorporate advanced technology to minimise radar cross-section and enhance invisibility to enemy detection systems, reducing the likelihood of detection and engagement.
Key Features
- Radar Cross-Section Reduction: The vessel’s hull and superstructure are designed to deflect and absorb radar waves, significantly lowering the ship’s visibility on enemy radar screens.
- Emission and Signature Management: Equipped with systems that control electromagnetic emissions from radar, radio, and other communications to minimise detection risks from enemy sensors.
- Infrared and Thermal Signature Minimization: Uses materials and designs that reduce infrared and thermal signatures, decreasing visibility to infrared and heat-seeking sensors.
- Acoustic Signature Reduction: Implements sound-absorbing materials and construction techniques to lower noise from machinery and propulsion, making detection by sonar more difficult.
- Operational Roles: Stealth frigates are versatile in modern naval warfare, suitable for anti-submarine warfare, anti-air warfare, maritime patrol, surveillance, and escort missions.
- Enhanced Survivability: The stealth capabilities of these frigates enhance their survivability by reducing detection and engagement ranges in naval operations.
Project 17A Frigates
- Project 17A frigates are an advanced version of the P17 (Shivalik Class) frigates, featuring enhanced stealth capabilities, modern weapons, sensors, and platform management systems.
- The Indian Navy ordered 7 stealth frigates: 4 are being built by Mazagon Dock Ltd (MDL) and 3 by Garden Reach Shipbuilders and Engineers (GRSE).
- Design and Development: The P17A ships were designed by the Navy’s Warship Design Bureau with about 75% of equipment and systems sourced from indigenous firms.
Launches and Progress:
- The first ship, ‘Nilgiri‘, constructed by MDL, launched on September 28, 2019.
- ‘Himgiri’, the first ship built at GRSE, launched on December 14, 2020.
- ‘Udaygiri’, launched on May 17, 2022, is anticipated to start sea trials in the latter half of 2024.
- ‘Dunagiri’, the fourth P17A frigate, launched in July 2022, is named after a mountain range in Uttarakhand.
- ‘Taragiri’, named after a Himalayan hill range in Garhwal, is the fifth ship in the series.
- ‘Vindhyagiri’, the last of the three ships built by GRSE, rounds out the trio constructed in Kolkata.
Kharchi Puja
- Kharchi is a major festival in Tripura, celebrated in July-August on the 8th day of the new moon.
- The term ‘Kharchi’ derives from the Tripuri words “Khar” or “Kharta” (sin) and “Chi” or “si” (cleaning), symbolising the cleansing of sins.
- The festival coincides with ‘Ashad Shukla Ashtami’.
- During the festival, fourteen deities are worshipped by the Royal priest known as ‘Chantai’.
- Kharchi Puja lasts 7 days and is held at the 14 Gods temple in old Agartala, also known as the ‘Chaturdasha Devata’ temple.
- The deities of Kharchi Puja are represented only by heads, not full bodies.
- On the day of the puja, these deities are carried by Chantai members to the river Saidra, where they are bathed with holy water and then returned to the temple.
