Tribes like Oraon, Munda, Santal, Khadia, and Ho celebrate it.

Notes:
Chief of Defence Staff (CDS) General Anil Chauhan inaugurated Techkriti 2025, Asia’s largest intercollegiate technical and entrepreneurial festival, at Indian Institute of Technology (IIT) Kanpur. The event focused on modernization of the Indian Armed Forces and future challenges in Cyber, Artificial Intelligence (AI), Quantum, and Cognitive domains. The theme “Panta Rhei” (Everything Flows) highlighted the continuous evolution of technology and innovation. A special Defence Expo ‘Rakshakriti’ showcased cutting-edge defence technology, fostering collaboration between armed forces, academia, and industry. The event promoted autonomous drones, advanced security tech, and reduced import dependence, inspiring students towards defence and technology careers.

Notes:
Andhra Pradesh Chief Minister launched the P4 Bangaru Kutumbam-Margadarsi initiative in Velagapudi on Ugadi. P4 stands for Public-Private-People Partnership, a mission-mode initiative for social and economic transformation. It aims to eradicate poverty and uplift marginalised families by creating model families called “Bangaru Kutumbam.” The initiative targets over 2 million beneficiaries in the initial phase. It provides free gas cylinders, educational support, and women empowerment schemes. The initiative promotes inclusive development, governance innovation, and a replicable welfare model for other states.

Notes:
Uttar Pradesh MSME Minister announced India’s first Textile Machine Park near Kanpur on 875 acres in Chaparghata village, Bhongaon. The park will follow the Public-Private Partnership (PPP) model to reduce imports and promote Make in India. It aims to manufacture textile machines currently imported from China, Vietnam, South Korea, Taiwan, and Europe. More than 200 large and medium units will be set up for machine production. Machines like circular knitting, flat knitting, printing, and technical textile machines will be manufactured. Local technical experts will be trained for repair and maintenance. Uttar Pradesh’s textile sector is witnessing rapid growth.

Notes:
The government has launched ZooWIN, a digital platform to track real-time availability of anti-rabies vaccines (ARV) and anti-snake venom (ASV) nationwide. ZooWIN is similar to Co-WIN and U-WIN, centralizing data for better coordination among healthcare providers, municipal authorities, and veterinary services. It supports the Union Health Ministry’s efforts to combat rabies and snakebites under the National Action Plan for Prevention and Control of Snakebite Envenoming (NAPSE). India records 3–4 million snakebites annually, causing around 50,000 deaths, half of the global snakebite mortality. The platform is initially piloted in Delhi, Madhya Pradesh, Assam, Puducherry, and Andhra Pradesh.

Notes:
SpaceX recently launched a private astronaut crew on a historic polar-orbiting mission from NASA’s Kennedy Space Center in Florida aboard a Falcon 9 rocket. A Polar Orbit (PO) is a type of Low Earth Orbit (LEO) between 200 km and 1,000 km in altitude. Unlike equatorial orbits, satellites in a polar orbit travel from pole to pole. Polar orbits allow satellites to cover the entire Earth’s surface as the planet rotates. These orbits are crucial for Earth observation, climate monitoring, and reconnaissance. The Fram2 mission is the first human spaceflight to use this trajectory, marking a milestone in space exploration.

Notes:
Researchers at the Indian Institute of Science (IISc) have developed a bacteria-based technique to repair bricks for lunar habitats. Future lunar missions, like NASA’s Artemis programme, aim to establish permanent settlements on the Moon. Instead of transporting materials from Earth, astronauts will use lunar soil, or regolith, to build structures. IISc developed a method using the bacterium Sporosarcina pasteurii to create bricks from lunar and Martian soil simulants. The bacterium converts urea and calcium into calcium carbonate crystals, binding soil particles with guar gum. This method is eco-friendly and cost-effective compared to cement.

Notes:
The Indian Naval Sailing Vessel Tarini reached Cape Town, South Africa, in its final international stop of the Navika Sagar Parikrama II global circumnavigation. INSV Tarini is a 56-foot, indigenously built sailing vessel commissioned in February 2017 by the Indian Navy. It was built by Aquarius Shipyard Ltd., Goa, under the Make in India initiative. It has advanced navigation, satellite communication, and emergency steering for extreme conditions. It was named after the Tara-Tarini hill shrine in Odisha, historically revered by sailors. The expedition began on October 2, 2024, covering 23,400 nautical miles across three oceans and three major capes in eight months.

Notes:
The Rajya Sabha passed the Protection of Interests in Aircraft Objects Bill, 2025, to implement international agreements on aviation leasing. It aligns with the Convention on International Interests in Mobile Equipment (Cape Town Convention, 2001) and its Protocol on Aircraft Equipment. India signed these agreements in 2008. The bill secures rights over aircraft, helicopters, and engines, ensuring legal clarity. It empowers the central government to make rules and designates the Directorate General of Civil Aviation (DGCA) as the registry authority for aircraft registration and de-registration, protecting creditors and aviation stakeholders under clear legal guidelines.
