Science & Technology Current Affairs MCQs

Notes:
Recent re-analysis of National Aeronautics and Space Administration (NASA) Cassini spacecraft data suggests that Saturn’s moon Titan may not have a subsurface ocean as earlier believed. Titan is the largest moon of Saturn and the second largest in the solar system after Ganymede. It was discovered by Dutch astronomer Christiaan Huygens. Titan has a radius of about 2,575 kilometres and is much wider than Earth’s Moon. It is the only moon with a dense atmosphere, mainly nitrogen with some methane. Titan is the only world besides Earth with rivers, lakes, and seas of liquid on its surface. It has an Earth-like methane cycle with rain, flow, and evaporation.

Notes:
A Legionnaires’ disease outbreak triggered a health alert in Sydney’s central business district, urging people to watch for symptoms. Legionnaires’ disease is a severe lung infection (pneumonia) caused by the bacterium Legionella. The disease was named after a 1976 outbreak at an American Legion convention in the United States. Legionella occurs naturally in freshwater sources like lakes, rivers and soil. Infection mainly happens by inhaling contaminated water droplets or soil particles. It does not spread from person to person and is not contagious. Older adults, smokers and immunocompromised people are at higher risk

Notes:
Kavach 4.0 has been commissioned on Gujarat’s first Bajwa (Vadodara)–Ahmedabad 96 km section. The section covers 17 stations with 23 towers, 20 Kavach huts, 192 km optical fibre cable and 2,872 Radio Frequency Identification (RFID) tags. Kavach is an indigenously developed Automatic Train Protection (ATP) system of Indian Railways. Kavach 4.0 prevents Signal Passed at Danger (SPAD) and head-on or rear-end collisions. It enforces automatic speed control and Permanent Speed Restrictions. Kavach is certified to Safety Integrity Level-4 (SIL-4) and approved by Research Designs and Standards Organisation (RDSO)

Notes:
Army Hospital (Research and Referral), Delhi, performed India’s first 3D Flex Aqueous Angiography with iStent. The procedure combines advanced imaging with minimally invasive glaucoma surgery. Glaucoma is a leading cause of irreversible blindness with silent progression. The surgery used a stand-mounted Spectralis system and a 3D operating microscope. The breakthrough allows real-time visualization of aqueous outflow pathways. Surgeons can deliver precise, targeted interventions, improving patient outcomes. The procedure positions Armed Forces Medical Services at the forefront of global ophthalmic care.

Notes:
Indian Space Research Organisation (ISRO)’s Polar Satellite Launch Vehicle-C62 (PSLV-C62) mission faced an anomaly at the end of the third stage (PS3), and a detailed technical investigation has been started. PSLV-C62 is a multi-payload mission carrying one primary satellite and 18 secondary payloads. It is ISRO’s first space launch of the year 2026, scheduled from Sriharikota spaceport. The primary payload is Earth Observation Satellite-N1 (EOS-N1), codenamed Anvesha. EOS-N1 is a hyperspectral imaging satellite developed mainly for the Defence Research and Development Organisation (DRDO).

Notes:
CSIR–National Institute of Science Communication and Policy Research (CSIR-NIScPR) marked its 5th Foundation Day, highlighting science communication and policy research. On this occasion, the SVASTIK portal (Scientifically Validated Societal Traditional Knowledge) was launched. SVASTIK is a national initiative to communicate India’s scientifically validated traditional knowledge to society. It provides content in English, 19 Indian languages, and 5 foreign languages, ensuring wide outreach. The portal brings all SVASTIK content to a single digital platform, improving accessibility and engagement. It strengthens public awareness, policy relevance, and global visibility of India’s traditional knowledge systems.

Notes:
Japan officially ended the Akatsuki mission after losing contact with the spacecraft for over a year. Akatsuki, also called PLANET-C or Venus Climate Orbiter (VCO), was operated by Japan Aerospace Exploration Agency (JAXA). It was the only active spacecraft orbiting Venus, studying volcanism and atmospheric dynamics, especially super-rotation.

Notes:
A rare blood-red aurora was recorded at the Indian Astronomical Observatory using an all-sky camera in Hanle, Ladakh. Hanle Dark Sky Reserve is located at about 4,500 metres altitude in the Changthang region of Ladakh. It lies within the Changthang Wildlife Sanctuary and has Bortle-1 category skies, the darkest level. It was notified in December 2022 and is India’s first International Dark Sky Reserve. The reserve is managed by the Indian Institute of Astrophysics under the Department of Science and Technology. It aims to reduce light pollution and promote astro-tourism for local livelihoods.

Notes:
Odisha government partnered with deep-tech startup BonV Aero to create a National Unmanned Aerial Vehicle (UAV) Test and Innovation Corridor. The corridor will be set up at Rangeilunda in Ganjam district. It will be India’s first commercial airport repurposed as a real-world drone testing facility. The agreement was signed at the Wings India 2026 summit in Hyderabad. BonV Aero will lead indigenous research, development, and testing of unmanned aviation systems. The corridor will allow live UAV trials in low-altitude airspace up to 1,000 metres.

Notes:
India entered the quantum era with the launch of the Amaravati Quantum Valley on 8 February 2026. It is supported by the ₹6,000 crore National Quantum Mission to make India a global deep-tech power. The Amaravati Quantum Valley is India’s first integrated quantum ecosystem spread over 50 acres. It brings together government, universities, and companies like International Business Machines (IBM) and Tata Consultancy Services (TCS). It is located in Andhra Pradesh. It will support healthcare, finance, defence, secure communication, and create jobs while strengthening national security.
