Science & Technology Current Affairs MCQs

Notes:
A new study found that Double Asteroid Redirection Test (DART) not only changed the motion of an asteroid but also slightly altered the orbit of the asteroid pair around the Sun. DART was launched in 2021 by National Aeronautics and Space Administration (NASA) to test asteroid deflection technology. It was the first planetary defence mission to change an asteroid’s path using the kinetic impact method. The spacecraft targeted a binary asteroid system of Didymos and its moonlet Dimorphos. In 2022, the spacecraft intentionally crashed into Dimorphos to alter its orbit around Didymos. The impact successfully changed the asteroid’s motion, proving humans can potentially deflect hazardous near-Earth objects in space.

Notes:
Researchers recently identified an unusual iron sulfate ferric hydroxysulfate in layered deposits near Valles Marineris using laboratory experiments and orbital data. Valles Marineris, also called Mariner Valley, is a vast system of interconnected canyons on Mars. It was discovered during the Mariner 9 mission in 1971. It is one of the largest canyon systems in the Solar System. Some canyon walls are fault scarps formed due to crustal movement linked to Tharsis Rise. Erosion also shaped the canyon, seen in deep gullies along the walls.

Notes:
Indian Council of Agricultural Research–Indian Veterinary Research Institute produced Sahiwal calves using OPU–IVF–ET (Ovum Pick-Up–In Vitro Fertilization–Embryo Transfer). Sahiwal cattle is one of the best milk-producing indigenous breeds of India. It originates from Sahiwal region in Montgomery district of Punjab in Pakistan. It is also known as Lambi Bar, Lola, Montgomery, Multani and Teli. The cows are brownish-red in colour with shades from mahogany to greyish red, while bulls have darker extremities.

Notes:
The Minor Planet Centre (MPC) recently announced discovery of 15 new moons, 4 around Jupiter and 11 around Saturn. It is the global centre for collecting and storing data on small solar system bodies. It operates under the International Astronomical Union (IAU) at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, United States. Astronomers send new findings to MPC, where data is verified and orbits are calculated. It assigns official names or designations to newly discovered objects. It tracks asteroids, comets, and outer planet moons.

Notes:
A Kerala start-up has delivered the Akasha300 3D printer to Indian Space Research Organisation (ISRO), boosting India’s self-reliance in advanced manufacturing. It is a high-temperature, multi-material extrusion 3D printer designed for industrial and research use. It is supported by the Space Technology Innovation and Incubation Centre at Indian Institute of Space Science and Technology (IIST) and Kerala Startup Mission. It uses dual-extrusion technology and can operate up to 350°C, with future upgrades to 500°C. It has a modular design allowing multiple extrusion systems and hybrid manufacturing.

Notes:
Indian Space Research Organisation conducts the YUva VIgyani KAryakram (YUVIKA) to promote scientific temper among school students. The YUVIKA (YUva VIgyani KAryakram) programme is an initiative of the Indian Space Research Organisation (ISRO). The programme provides foundational knowledge in space technology, space science, and space applications, with special focus on students from rural areas. Its objective is to create awareness about emerging trends in science and encourage students to pursue Science, Technology, Engineering and Mathematics (STEM) careers.

Notes:
India has successfully demonstrated a 1,000-kilometre quantum communication network under the National Quantum Mission, a major breakthrough in secure communication technologies. The National Quantum Mission (NQM) was launched by the Department of Science & Technology with an outlay of Rs.6003 crore for 2023-24 to 2030-31. Its objective is to seed, nurture, and scale up scientific and industrial research and development (R&D) and create an innovative ecosystem in Quantum Technology (QT). It is one of nine initiatives under the Prime Minister’s Science Technology Innovation Advisory Council (PM-STIAC).

Notes:
Institute of Nano-Science and Technology, Mohali, developed a new material to detect nicotine and cotinine using fluorometric sensing. Fluorometric sensing is a technique that measures substances through fluorescent emission. The material “lights up” on contact with nicotine/cotinine, enabling quick detection. It is based on Iron-based Metal-Organic Framework (Fe-MOF), a nano-structured porous material. It detects even small amounts accurately, improving over traditional methods. The material is biocompatible (safe for living cells) and works at in-vitro stage.

Notes:
Recently, Rocklink India Pvt. Ltd. set up an integrated recycling facility in Sikandrabad UPSIDC Industrial Area, Uttar Pradesh. The plant focuses on recycling lithium-ion batteries, rare earth magnets, and metal-bearing industrial waste. It has a capacity of 10,000 tonnes/year for lithium-ion batteries and 60 tonnes/month for rare-earth magnets. A rare-earth chloride processing unit (1,500 tonnes/year) is planned for 2026. The initiative supports domestic recovery of critical minerals and promotes a circular economy.

Notes:
Scientists from Centre for Nano and Soft Matter Sciences, Bengaluru, developed a smart material that can both store energy and indicate charge level through colour change. The material is an oxygen-deficient bimetallic oxide made of molybdenum and tungsten. It appears blue when charged and transparent when discharged, enabling real-time visual monitoring. The innovation uses oxygen vacancies to enhance ion movement and alter electronic structure. It was synthesised using the solvothermal method.
