Perseverance, also called “Percy”, is part of the Mars 2020 Mission. It landed in 2021 inside the ancient river delta of Jezero Crater. Its main goal is to search for signs of past life and collect rock and soil samples for future return to Earth. It can detect organic matter, study minerals, map chemical composition, and closely observe distant terrain. It is the first rover to record sounds on Mars and send them back to Earth.
42. Where was India’s first private-sector navigation innovation hub inaugurated?
[A] Pune
[B] Bengaluru
[C] Hyderabad
[D] Thiruvananthapuram
Show Answer
Correct Answer: D [Thiruvananthapuram]
Notes:
ISRO Chairman V Narayanan inaugurated Ananth Technologies’ Ananth Centre of Excellence for Navigation (ACEN) in Thiruvananthapuram. ACEN is India’s first private-sector navigation innovation hub. Ananth Technologies, founded in 1992, contributes to ISRO and Defence Research and Development Organisation (DRDO) missions with expertise in precision sensors, airworthiness, and system integration. Navigation is crucial for missiles, aircraft, ships, and satellites; reliance on foreign GPS revealed strategic vulnerabilities. ACEN will handle Maintenance, Repair, and Overhaul (MRO) of navigation systems domestically.

[A] Niger
[B] Rwanda
[C] Algeria
[D] Ethiopia
Show Answer
Correct Answer: A [Niger]
Notes:
Niger became the first country in the African Region to eliminate onchocerciasis, also called river blindness. Niger is the fifth country worldwide to stop transmission of Onchocerca volvulus parasite. Other successful countries are Colombia, Ecuador, Guatemala, and Mexico in the Americas. World Health Organisation (WHO) praised Niger’s strong leadership and public health efforts. Onchocerciasis is the second leading infectious cause of blindness after trachoma. It spreads through bites of infected black flies found near rivers. It mainly affects rural areas of sub-Saharan Africa and Yemen, and some parts of Latin America.
44. Which organization has launched the AviSpray-10c agricultural spraying drone?
[A] Defence Research and Development Organisation
[B] AvironiX Drones
[C] Indian Space Research Organisation
[D] IIT Madras
Show Answer
Correct Answer: B [AvironiX Drones]
Notes:
AvironiX Drones, a deep-tech company based in Chennai, has launched a new agricultural spraying drone called AviSpray-10c. The AviSpray-10c is a compact and smaller next-generation spraying drone, designed specifically for Indian farming needs. The drone was developed to reduce the cost, operational difficulty, and manpower requirements usually associated with drone-based crop spraying. Unlike many drones built only in laboratory settings, the AviSpray-10c has been tested and validated through extensive real-world field deployments.
45. What is the name of the Chandrayaan-3 lander payload that detected the active plasma environment at the Moon’s south pole?
[A] RAMBHA-LP
[B] ChaSTE
[C] ILSA (Instrument for Lunar Seismic Activity)
[D] LRA (LASER Retroreflector Array)
Show Answer
Correct Answer: A [RAMBHA-LP]
Notes:
Chandrayaan-3’s lander payload RAMBHA-LP (Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere – Langmuir Probe) detected an active plasma environment in the Moon’s south polar region. Plasma, the 4th state of matter, is electrically neutral and contains charged particles like ions and free electrons. RAMBHA-LP uses a hypersensitive Langmuir probe mounted on a boom to avoid interference from the lander. It measures electron density and electron temperature near the lunar surface, helping understand the plasma behaviour at the Moon’s South Pole.
46. Which institution has conducted India’s first clinical trial of the Supernova Stent for stroke?
[A] Indian Council of Medical Research (ICMR)
[B] National Institute of Mental Health and Neurosciences (NIMHANS)
[C] All India Institute of Medical Sciences (AIIMS), New Delhi
[D] Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh
Show Answer
Correct Answer: C [All India Institute of Medical Sciences (AIIMS), New Delhi]
Notes:
AIIMS, New Delhi has conducted India’s first clinical trial of an indigenously evaluated advanced stroke treatment device named the Supernova Stent, marking a major milestone in India’s medical research and device innovation. The Supernova Stent is specifically designed for India’s diverse patient population, where strokes tend to occur at a younger age compared to Western countries, making it more suitable for local clinical needs. AIIMS highlighted that this is India’s first stroke intervention device to receive clearance based entirely on a domestic clinical trial, strengthening confidence in indigenous clinical research capabilities.
47. Kavach system has been developed by which organization?
[A] Defence Research and Development Organisation (DRDO)
[B] Research Designs and Standards Organisation (RDSO)
[C] Indian Space Research Organisation (ISRO)
[D] Bharat Electronics Limited (BEL)
Show Answer
Correct Answer: B [Research Designs and Standards Organisation (RDSO)]
Notes:
Kavach is an indigenously developed Automatic Train Protection (ATP) system designed to improve railway operational safety across the Indian Railways network. It was developed by the Research Design and Standards Organisation (RDSO) of Indian Railways. As of December 2025, the system has been commissioned on over 2,000 km of railway routes, with 7,129 km of Optical Fibre Cable (OFC) laid, 860 telecom towers installed, 767 stations connected, 3,413 km of trackside equipment deployed, and 4,154 locomotives fitted with Kavach. About 40,000 technicians and operators have been trained, reflecting the scale of operational readiness.
48. Which institute has developed a peptide therapy for fungal keratitis, a severe infection of the cornea?
[A] All India Institute of Medical Sciences (AIIMS), Delhi
[B] Bose Institute, Kolkata
[C] Indian Institute of Science (IISc), Bengaluru
[D] Indian institute of Technology (IIT), Delhi
Show Answer
Correct Answer: B [Bose Institute, Kolkata]
Notes:
Researchers from Bose Institute, Kolkata, in collaboration with L V Prasad Eye Institute, Hyderabad, have developed a peptide therapy for fungal keratitis, a severe infection of the cornea. They designed a 15-residue peptide, SA-XV, derived from the host-defense peptide S100A12, previously known to inhibit fungal growth. SA-XV acts by interacting with fungal cell walls and membranes, translocating into the cytoplasm, binding nuclear DNA to halt the cell cycle, and targeting mitochondria to induce apoptosis.
