The launch marked the 64th flight of Polar Satellite Launch Vehicle (PSLV) and 9th dedicated commercial mission undertaken by New Space India Limited (NSIL).
- NSIL, incorporated in 2019, is wholly owned Government Company under administrative control of Department of Space and is the commercial arm of Indian Space Research Organisation (ISRO).
About PSLV-C62 / EOS-N1 Mission
- It includes the launch of EOS-N1 earth observation satellite along with 15 co-passenger satellites from domestic & international customers.
- EOS-N1 is designed to strengthen space-based monitoring capabilities.
- It will also demonstrate KID or Kestrel Initial Technology Demonstrator from a Spanish startup.
- KID is a small-scale prototype of a re-entry vehicle which after launch is slated to re-enter the earth’s atmosphere towards splashdown in South Pacific Ocean.
- EOS-N1 and 14 Co-passenger satellites will be injected into a Sun Synchronous Orbit and KID Capsule into a re-entry trajectory.
About PSLV
- 3rd generation launch vehicle and is first Indian launch vehicle to be equipped with liquid stages.
- Workhorse of ISRO: Consistently delivered satellites to Low Earth Orbits, can take up to 1,750 kg of payload to Sun-Synchronous Polar Orbits of 600 km altitude.
- Stages in PSLV
- First Stage: Uses the S139 solid rocket motor augmented by 6 solid strap-on boosters.
- Second Stage: Uses Earth storable liquid rocket engine known as Vikas engine, developed by Liquid Propulsion Systems Centre.
- Third Stage: Solid rocket motor that provides high thrust to upper stages.
- Fourth Stage: Uppermost stage of PSLV, comprising of two Earth storable liquid engines.
- Notable Missions: Chandrayaan-1, Mars Orbiter Mission, Aditya-L1 and Astrosat Mission, PSLV set a world record by launching 104 satellites in a single mission in 2017.

1 sourcePixxel-led Consortium has signed an agreement with IN‑SPACe to design, build, and operate India’s first national EO constellation

- Pixxel-led Consortium comprises Piersight Space, Satsure Analytics India, and Dhruva Space.
- Indian National Space Promotion and Authorisation Centre (IN-SPACe) is India’s nodal agency that authorises, regulates, and promotes private sector participation in space activities.
Key features of the EO constellation Project
- PPP Model: It will be executed under a Public–Private Partnership (PPP) framework.
- The project will create a complete end-to-end Earth Observation ecosystem, from satellite deployment to value-added geospatial analytics.
- Constellation: It will consist of 12 satellites covering very high-resolution optical, multispectral, synthetic aperture radar (SAR), and hyperspectral imaging.
- Project scale: ₹1,200 crore investment over a5-year period.
- Strategic shift: Transition from government-built to industry-operated national EO infrastructure.

Based on observations from James Webb Space Telescope, astronomers unveil a detailed map of dark matter.
Dark Matter
- It is a hypothesised form of matter that is invisible but is inferred to exist based on its gravitational effects on ordinary matter like stars, planets, moons, etc.
- It does not emit, absorb, or reflect light and barely interacts with normal matter.
- Composition of Universe: normal or visible matter (5%), dark matter (27%), and dark energy (68%).

1 sourceWEF announced five new ‘Fourth Industrial Revolution (IR 4.0) Centres’ globally. One of the Centre will be built in in Andhra Pradesh, India.
- It will be 3rd such centre in India after Mumbai and Telangana.
What is the Fourth Industrial Revolution?
- The term was coined by Klaus Schwab, founder of the World Economic Forum (WEF) in 2016.
- IR 4.0 describes the current era in which digital, physical and biological technologies converge such as AI, robotics, the Internet of Things (IoT), Quantum Computing, etc.
- Unlike earlier revolutions, IR 4.0 is blurring boundaries between physical, digital and biological systems.
Significance of Fourth Industrial Revolution
- Economic growth: Enhances productivity and improves supply chain resilience through automation, data analytics and smart manufacturing.
- Inclusive development potential: Offers developing countries like India an opportunity to leapfrog legacy technologies and expand digital access.
- Environmental sustainability: Supports low-carbon and resource-efficient growth through smart grids, precision agriculture and circular economy practices.
- For example, "Lighthouse" factories have demonstrated significant reductions in CO2 emissions and water usage through predictive analytics and IoT.
- Human capital centrality: Shifts the focus from physical labour to skills, innovation, and lifelong learning.

Government releases draft guidelines for Battery Pack Aadhaar System.
About Battery Pack Aadhaar System
- It is an indigenous digital identification and data storage system developed to ensure end-to-end traceability of batteries throughout their entire lifecycle.
- It includes a unique identification number for each battery pack, capturing and storing vital information from extraction to final disposal.
- Battery categories that are required to maintain a Battery Pack Aadhaar as an electronic record include Electric Vehicle Batteries and Industrial Batteries with capacity greater than 2kWh.
- Significance: Enabling second-life usage, regulatory compliance, and efficient recycling.
Union Road Transport and Highways Minister announced that India will roll out Vehicle-to-Vehicle (V2V) communication technology.
About V2V Communication Technology
- It is an inter vehicle communication paradigm that it does not rely on third party networks like cellular networks to communicate.
- Significance: Increased safety as it works across the front, rear and sides of vehicles, and will factor in terrain and road curves; strengthen Advanced Driver Assistance Systems (ADAS) by allowing vehicles to share warnings even when a hazard is not visible.
Indian scientists developed first supercomputer-powered simulation to capture Mpemba effect.
About Mpemba effect
- It is a long-existing paradox suggesting that hotter substances can freeze faster than colder substances under certain conditions.
- Most famously, observed with water, but the effect is not limited to water and shows up in other materials and physical systems, too.
- Significance: Heat engines and refrigeration systems, Quantum computing, Materials science etc.
