1. What is the name of ISRO’s recently launched mission, reported on April 3, 2026, which aims to study exoplanetary atmospheres for signs of habitability using advanced spectroscopy?
A) Aditya-L2
B) Gaganyaan-2
C) Shukrayaan-2
D) ExoSonde-1
Correct answer: D) ExoSonde-1 Notes: ISRO’s ambitious ExoSonde-1 mission, successfully launched on April 1, 2026, represents a significant leap in India’s space exploration capabilities. This cutting-edge orbital observatory is equipped with high-resolution spectrographs designed to analyze the atmospheric compositions of exoplanets identified by ground-based telescopes. Its primary objective is to detect potential biosignatures—gases like oxygen, methane, or water vapor—that could indicate the presence of life beyond our solar system. The data gathered by ExoSonde-1 will be crucial for astronomers worldwide in refining models of planetary formation and accelerating the search for habitable worlds. This mission underscores India’s growing leadership in advanced astrophysics.
2. The “Global Ocean Stewardship Alliance” (GOSA), a new international body focused on marine conservation and sustainable blue economy practices, reportedly held its inaugural summit in which city in early April 2026?
A) Cape Town
B) Geneva
C) Singapore
D) Reykjavik
Correct answer: A) Cape Town Notes: The Global Ocean Stewardship Alliance (GOSA) convened its inaugural summit in Cape Town, South Africa, from April 1-3, 2026. This newly formed alliance brings together key maritime nations, UN agencies, and leading environmental organizations to address the escalating challenges faced by global oceans. GOSA’s mandate includes developing comprehensive strategies to combat plastic pollution, curb illegal, unreported, and unregulated (IUU) fishing, and promote responsible aquaculture. The Cape Town Declaration, issued at the summit’s conclusion, outlined ambitious targets for restoring marine biodiversity and fostering a sustainable blue economy that benefits coastal communities while protecting vital ocean ecosystems.
3. The Indian government, on April 3, 2026, launched the “National Green Infrastructure Fund” (NGIF) to accelerate investments in sustainable urban development and renewable energy projects. Which ministry is primarily responsible for overseeing this fund?
A) Ministry of Finance
B) Ministry of Environment, Forest and Climate Change
C) Ministry of Housing and Urban Affairs
D) NITI Aayog
Correct answer: A) Ministry of Finance Notes: The Ministry of Finance is the nodal ministry for the newly launched National Green Infrastructure Fund (NGIF), announced on April 3, 2026. This landmark initiative aims to channel significant public and private sector investments towards India’s green transition goals. The NGIF will primarily fund projects related to renewable energy infrastructure, sustainable transport, waste management, and green buildings in urban centers. By leveraging a mix of government allocations, green bonds, and public-private partnerships, the fund seeks to create a robust financial ecosystem for sustainable development. This move is expected to boost India’s climate resilience and contribute significantly to its net-zero emission targets.
4. India’s Ministry of Defence reportedly signed a landmark deal on April 2, 2026, to acquire advanced “Varunastra-II” autonomous underwater vehicles (AUVs) for its naval fleet. These AUVs are primarily designed for what purpose?
A) Anti-submarine warfare and mine countermeasures
B) Deep-sea exploration and mapping
C) Coastal surveillance and patrol
D) Port security and harbor defence
Correct answer: A) Anti-submarine warfare and mine countermeasures Notes: The acquisition of “Varunastra-II” AUVs, announced by the Ministry of Defence on April 2, 2026, marks a strategic enhancement of the Indian Navy’s capabilities. These indigenously developed autonomous underwater vehicles are specifically engineered for advanced anti-submarine warfare (ASW) and highly effective mine countermeasures (MCM) operations. Equipped with sophisticated sonar systems, artificial intelligence-driven navigation, and stealth technology, Varunastra-II can operate autonomously for extended periods, detecting and neutralizing underwater threats with precision. This induction is critical for bolstering India’s maritime security, safeguarding its coastal interests, and ensuring freedom of navigation in key strategic waterways, aligning with the nation’s naval modernization goals.
5. A new drought-resistant, high-yield variety of millet, ‘Suryashakti-M’, was formally released to farmers across several states on April 3, 2026, by the Indian Council of Agricultural Research (ICAR). This development is crucial for addressing which of the following challenges?
A) Boosting export competitiveness of Indian cereals
B) Enhancing food security amidst changing climate patterns
C) Reducing pesticide usage in food crops
D) Supporting livestock feed production exclusively
Correct answer: B) Enhancing food security amidst changing climate patterns Notes: The Indian Council of Agricultural Research (ICAR) launched ‘Suryashakti-M’ on April 3, 2026, a groundbreaking millet variety specifically developed for drought-prone regions. This new variety boasts exceptional water-use efficiency and offers significantly higher yields compared to traditional millets, even under severe water stress. Its release is a crucial step towards strengthening India’s food security in the face of increasingly unpredictable climate patterns and frequent droughts. ‘Suryashakti-M’ encourages crop diversification, reduces farmers’ reliance on water-intensive crops, and promotes sustainable agricultural practices. It also contributes to improving the nutritional security of vulnerable populations, aligning with the nation’s commitment to climate-resilient agriculture.
