Science & Technology Current Affairs MCQs

Notes:
Recently, India and the United States marked their first space collaboration with the successful launch of NISAR (NASA-ISRO Synthetic Aperture Radar) by ISRO’s GSLV-F16 rocket. GSLV (Geosynchronous Satellite Launch Vehicle) injected NISAR into the Sun Synchronous Polar Orbit (SSPO) at around 745 km altitude in a 19-minute flight. The NISAR (NASA-ISRO Synthetic Aperture Radar) is the world’s first Earth observation satellite mission between the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO). It will study land deformation, ice movement, ecosystems, and oceanic regions with high precision.

Notes:
Seeds of seabuckthorn and Himalayan tartary buckwheat grown in Ladakh’s cold desert are part of NASA’s Crew-11 experiment on the International Space Station (ISS). The seeds were sourced by Indian space start-up Protoplanet based in Bengaluru. The mission launched on August 1, 2025, from Florida and docked at ISS on August 2, 2025. The experiment aims to test how seeds react to space stress and microgravity before germination. It focuses on gene activation and metabolic processes vital for space agriculture. Himalayan tartary buckwheat and seabuckthorn are rich in nutrients and suitable for long-duration space missions.

Notes:
V. O. Chidambaranar (VOC) Port, Thoothukudi, became the first Indian port to produce green hydrogen and achieve over 1 MW rooftop solar power generation. The announcement came during the Green Ports and Shipping Conference under NAVIC Cell-3 (Green Initiatives and Pollution Control), Ministry of Ports, Shipping and Waterways. The event is part of roadshows ahead of India Maritime Week 2025 in Mumbai, showcasing maritime sustainability and innovation. The conference discussed maritime decarbonisation, green financing, and policy frameworks for achieving India’s 2070 net-zero target.

Notes:
The National Supercomputing Mission (NSM) was launched in April 2015 by the Government of India with a budget of Rs.4,500 crore. Its vision is to achieve self-reliance and global leadership in supercomputing and provide state-of-the-art facilities to researchers. It is jointly implemented by the Ministry of Electronics and Information Technology (MeitY) and the Department of Science and Technology (DST) through Centre for Development of Advanced Computing (C-DAC), Pune and Indian Institute of Science (IISc), Bengaluru. As of August 2025, 37 supercomputers with 40 Petaflops capacity are installed across IITs, IISc, R&D labs and Tier-II/III cities. This information was submitted in the Lok Sabha today by Shri Jitin Prasada, Minister of State for Electronics and Information Technology.

Notes:
NASA has launched “Surya”, an artificial intelligence (AI) model to improve space weather forecasting. Surya was developed in collaboration with IBM and trained on over nine years of data from NASA’s Solar Dynamics Observatory (SDO). It analyses massive streams of solar activity to detect early signs of solar flares and coronal mass ejections (CMEs). Solar storms can disrupt satellites, communication systems, aviation, GPS navigation, and power grids on Earth. Surya generates visual forecasts up to two hours in advance with higher accuracy than traditional methods. The model is open-source to enable global researchers to improve space weather defense.

Notes:
Recently, the National Accreditation Board for Testing and Calibration Laboratories (NABL) launched its new Medical Application Portal. NABL is a non-profit autonomous organisation registered under the Societies Registration Act XXI of 1860. It functions under the administrative control of the Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry. The new portal aims to streamline medical testing and accreditation processes efficiently.

Notes:
Israeli defense technology firm Elbit Systems recently launched its advanced JUPITER space camera aboard the National Advanced Optical System (NAOS) satellite. The satellite was launched from Vandenberg Space Force Base, California, on a SpaceX Falcon 9 rocket. JUPITER supports military operations, environmental monitoring, scientific research, and wide-span observation missions. It features a large aperture, lightweight design, high-resolution panchromatic channel for black-and-white imaging, and a Near Infrared (NIR) channel for vegetation, water, and material analysis. The camera can capture continuous long image strips covering large areas efficiently.

Notes:
For decades, aspirin was the main drug to prevent heart attacks and strokes. A new study presented at the European Society of Cardiology congress and published in The Lancet shows clopidogrel, a blood-thinning antiplatelet drug, may be more effective. Review of seven clinical trials with 29,000 coronary artery disease patients found clopidogrel 14% more effective than aspirin in lowering major cardiovascular risks. Importantly, there was no higher risk of serious bleeding compared to aspirin. Clopidogrel (a P2Y₁₂ inhibitor) works by blocking platelet receptors to stop dangerous blood clots. It is low-cost, widely available, and safe, making it a strong candidate to replace aspirin in treatment guidelines.

Notes:
India unveiled its first fully indigenous 32-bit microprocessor, Vikram 3201, at Semicon India 2025. It is designed by Vikram Sarabhai Space Center (VSSC) and fabricated by Indian Space Research Organisation’s (ISRO) Semiconductor Laboratory (SCL), Chandigarh. Vikram 3201 is designed specifically for rockets and satellites, unlike processors in smartphones or laptops. It is an upgrade of Vikram 1601, a 16-bit processor used in ISRO launch vehicles since 2009. The processor manages navigation, control, and mission management in launch vehicles. The launch supports India’s semiconductor self-reliance, with five units under construction under the Design-Linked Incentive scheme.

Notes:
Indian Institute of Technology Hyderabad (IIT Hyderabad) signed a Memorandum of Understanding (MoU) with Army Training Command (ATC), Shimla. The partnership establishes a Centre of Excellence (CoE) named VIGRAHA (Virtual, Intelligent, Ground-breaking Research in AR/VR and High-tech Applications for Indian Army). The Simulator Development Division (SDD), Secunderabad represents the Indian Army in this collaboration. The CoE will focus on Augmented Reality (AR), Virtual Reality (VR), Artificial Intelligence (AI), Robotics, unmanned systems, and emerging defense technologies. The initiative strengthens India’s self-reliance (Atmanirbhar Bharat) in defense technologies.
