Science & Technology Current Affairs MCQs

Notes:
NASA’s SPHEREx mission recently observed interstellar comet 3I/ATLAS, the third such object discovered in our solar system. SPHEREx stands for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer. It is a NASA Astrophysics mission launched on March 11, 2025. The telescope has a megaphone-shaped design and will conduct an all-sky spectral survey. It surveys the sky in optical and near-infrared light, which helps study cosmic phenomena invisible to the human eye.

Notes:
In the Union Budget, the government approved National Large Solar Telescope (NLST) and National Large Optical–Near Infrared Telescope. National Large Solar Telescope (NLST) is a 2-metre aperture solar telescope being set up at Merak near Pangong Tso Lake. It will study the Sun in visible and near-infrared wavelengths of the electromagnetic spectrum. It will help in understanding solar dynamics, magnetism and space weather affecting Earth and satellites. National Large Solar Telescope (NLST) will become India’s third ground-based solar observatory.

Notes:
India’s first government-supported National Biobank for Lysosomal Storage Disorders (LSDs) was launched in February 2026 at the Foundation for Research in Genetics and Endocrinology (FRIGE) in Ahmedabad, Gujarat. It is funded by the Department of Biotechnology (DBT). This facility stores biological samples and data from 530 patients across 15 states to advance research, develop affordable diagnostic tools, and improve treatment for rare metabolic disorders.

Notes:
Waaree Energies will set up India’s largest lithium-ion battery gigafactory at Rambilli, Anakapalli district, Andhra Pradesh. Total investment is ₹8,175 crore for a greenfield project. The plant will have 16 Gigawatt-hour (GWh) capacity. It will cover full battery value chain: cell manufacturing, battery packs and Battery Energy Storage Systems (BESS). It received in-principle approval from State Investment Promotion Board. The project supports clean-energy goals of Andhra Pradesh.

Notes:
Van Allen Probes A satellite, weighing about 600 kg, is re-entering Earth’s atmosphere, raising discussion about possible ground risks. The Van Allen Probes mission by NASA was the first mission to study Earth’s radiation belts using two spacecraft together. The twin spacecraft Van Allen Probe A and Van Allen Probe B were launched on 30 August 2012 to explore Earth’s radiation environment. They studied the Van Allen Radiation Belts, which are rings of energetic charged particles trapped by Earth’s magnetic field. These belts are named after space scientist James Van Allen, who discovered them in 1958.

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:
India’s Antariksh Venture Capital Fund will start investing in space startups from FY2027 to boost the private space sector. It is a close-ended fund registered with Securities and Exchange Board of India as a Category II Alternative Investment Fund (AIF). Key investor is Indian National Space Promotion and Authorization Centre under the Department of Space. The fund is sponsored by SIDBI Venture Capital Limited. The objective is to provide capital for space startups, support scaling, and promote commercialization of technologies.

Notes:
As part of Gaganyaan mission, the Indian Space Research Organisation is conducting Mission MITRA (Mapping of Interoperable Traits and Response Assessment) in Leh from April 2 to April 9, 2026. Mission MITRA is a first-of-its-kind team behavioral study, developed jointly by ISRO and the Institute of Aerospace Medicine, aimed at evaluating crew safety and performance in human spaceflight. The study focuses on team communication, adaptability to stress, psychological resilience, and mutual support, which are critical for mission success. Leh’s high-altitude environment (approx 3,500 metres), hypoxia, low temperature, and isolation serve as a natural analog for spaceflight operations.

Notes:
The Drugs Controller General of India (DCGI) has approved Qdenga for individuals aged 4–60 years, making it India’s first dengue vaccine. Qdenga is a live-attenuated, tetravalent vaccine developed by Takeda Pharmaceutical, Japan. It targets all four dengue virus serotypes (DENV-1 to DENV-4), with strongest efficacy against DENV-2 and relatively lower against DENV-3 and DENV-4. It does not require pre-vaccination screening and is administered in two doses, spaced three months apart. The vaccine provides strong protection against severe dengue and reduces hospitalisation rates.

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.
