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:
Avataar is India’s first amphibious drone, launched on 5 March 2026 by AquaAirX Autonomous Systems. It can operate both in air and underwater, combining drone flight with submarine-like diving for surveillance. The project received ₹12.5 crore seed funding from Rainmatter. It has reached TRL-6 (Technology Readiness Level-6), meaning a working prototype tested in real environments. It is built with carbon fibre body and anti-corrosion coatings to resist saltwater damage.

Notes:
Asteroid 2024 YR4 was recently confirmed by NASA to not collide with the Moon in 2032. It is an Apollo-type asteroid, meaning its orbit crosses Earth’s orbit but remains mostly outside it. It was discovered in 2024 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile. In its name, Y indicates discovery in the second half of December, while R4 shows it was the 117th asteroid identified in that period. It is a Near-Earth Object (NEO) with size about 174–220 feet (53–67 metres). It likely originated from the central Main Asteroid Belt between Mars and Jupiter.

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:
New research confirmed that the Silverpit Crater was formed by a massive asteroid impact millions of years ago. It lies about 700 metres beneath the seabed in the North Sea, nearly 80 miles off the coast of Yorkshire. The crater was buried under thick sediment layers and was discovered only in 2002. It formed when a high-velocity space rock struck the seabed around 43–46 million years ago. Scientists found “shocked” quartz and feldspar crystals, which form only under extreme pressure during asteroid impacts. The crater is about 3 km wide and surrounded by circular faults extending nearly 20 km.

Notes:
United States-based Sentynl Therapeutics, part of Zydus Lifesciences, has partnered with South Korea’s PRG S&T to develop Progerinin, a drug for Hutchinson-Gilford Progeria Syndrome (HGPS). Hutchinson-Gilford Progeria Syndrome (HGPS) is an extremely rare genetic disorder that causes rapid aging in children. The disease is caused by a mutation in the LMNA (Lamin A) gene, which normally produces lamin A protein for maintaining cell structure. This mutation leads to the formation of an abnormal protein called progerin, which damages the cell nucleus. The damaged cells die early, resulting in premature aging of the body.

Notes:
Researchers at Indian Institute of Technology (IIT) Guwahati developed a new MXene-based material for hydrogen fuel production and seawater desalination. The material shows very low Hydrogen Evolution Reaction (HER) overpotential of 12 mV, better than Platinum/Carbon (Pt/C) electrodes, indicating high efficiency. Hydrogen is a clean fuel producing only water, but current production depends on fossil fuels, so this method offers a sustainable alternative. The material also enables solar-powered desalination, addressing the shortage of safe drinking water. Scientists modified MXene into ultra-thin ribbon-like structures to increase surface area and improve charge transport.

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:
Agnikul Cosmos has achieved a major milestone by successfully test-firing the Agnite Engine, marking progress in India’s private space sector. Agnite is the world’s largest single-piece 3D-printed booster engine, showcasing advanced additive manufacturing technology. It is part of a family of engines including Agnite and Agnilet, which are 3D-printed semi-cryogenic engines developed by Agnikul. These engines are specifically built to power the booster stage of Agnikul’s Agnibaan launch vehicle.

Notes:
Biotechnology Research and Innovation Council (BRIC) held its first Research Advisory Board meeting at Regional Centre for Biotechnology. BRIC is an apex autonomous body registered as a society. It was formed by merging 14 institutes of DBT (Department of Biotechnology). It provides centralized governance and funding through intra-mural core grants. It aims to build future scientific leaders and innovation ecosystem. It promotes cutting-edge biotech research aligned with national priorities. It works under Ministry of Science and Technology.
