Artemis II is a crewed lunar flyby mission that has surpassed the distance record of Apollo 13 (400,171 km), making it the farthest humans have travelled from Earth.
Summary (with lunar missions evolution): • Since 1958: 77+ Moon missions by multiple countries.
Key milestones: • Luna 9 → first soft landing • Apollo 11 → first human landing • Chang’e 4 → far side landing • Chandrayaan-3 → south pole landingWhat Artemis II shows: • Return of humans to deep space (after ~50 years) • Step towards future Moon landing (Artemis III)
After political transition in Bangladesh, ties with India are being reset through high-level engagement, moving from leader-centric to institutional relations.
Key Issues
2.1 Political Trust • Post-Hasina phase → trust deficit + demand for neutrality
India’s Kalpakkam Fast Breeder Reactor (PFBR) attaining criticality marks the operationalisation of Stage 2 of India’s nuclear programme. This is important because it connects India’s present uranium-based reactors with its long-term goal of thorium-based energy.
India’s Nuclear Programme
India’s programme is designed around its resource reality: • Limited uranium • Large thorium reserves
So, the strategy is sequential: Use uranium → generate plutonium → use plutonium to activate thorium
Three-Stage Nuclear Programme
Stage 1 – Uranium Stage • Reactors: Pressurised Heavy Water Reactors (PHWRs) • Fuel: Natural uranium
What happens: • Uranium undergoes fission → produces electricity • Side output: Plutonium is generated inside the reactor
Understanding: This stage is not just for power; it is mainly to produce plutonium, which India lacks naturally.
What happens: • Plutonium produces energy • At the same time, it converts unused material (Uranium-238) into more plutonium • Also produces excess neutrons
Understanding: This stage does two critical things:
Multiplies nuclear fuel (breeding)
Generates the neutron environment required to use thorium
What happens: • Thorium itself cannot produce energy directly • It absorbs neutrons (from Stage 2 system) • Converts into Uranium-233, which is a usable fuel
Then: • Uranium-233 undergoes fission → produces electricity • Can sustain further reactions
Understanding: Thorium becomes useful only after conversion, and that conversion depends on plutonium-driven reactions of Stage 2.
Why PFBR is crucial
• Without Stage 2: • Thorium cannot be effectively utilised
• PFBR enables: • Transition from fuel-consuming system → fuel-generating system
• Makes India: • Capable of long-term, resource-based nuclear energy independence
• Piprahwa relics (1898, UP) returned to Leh (Ladakh) after ~127 years • Event = civilisational recovery of Buddha-linked heritage
Piprahwa Relics (Basics)
• Contents → Bone fragments | reliquary caskets | ritual objects • Association → Buddha / Shakya clan • Importance → One of the earliest major Buddhist relic discoveries in India
Ladakh’s Historical Role
• Buddhist corridor (not a peripheral region) • Connectivity → India → Central Asia → China (Khotan) • Function → Spread of monks | texts | art | ideas
Evidence in Region
• Locations → Suru | Dras | Khaltse | Mulbekh • Remains → Stupas | inscriptions | rock carvings | Maitreya statue • Link → Kashmir–Gandhara Buddhist tradition
Core Argument
• Ladakh = Civilisational + heritage zone • Not only = Strategic/military frontier
Diplomacy Angle
• Buddhism → India’s soft power tool • Ladakh → Gateway for Buddhist diplomacy (Central & East Asia)
About the UPSC Civil Services Examination (UPSC CSE)
The UPSC Civil Services Examination (CSE) is one of the most competitive and esteemed examinations in India, conducted by the Union Public Service Commission to recruit officers for services such as the Indian Administrative Service (IAS), Indian Police Service (IPS), Indian Foreign Service (IFS), and others. The exam comprises three stages — Prelims, Mains, and the Personality Test (Interview) — designed to test a candidate’s knowledge, aptitude, decision-making, and leadership skills.
How to Prepare Effectively for UPSC CSE
Cracking the UPSC CSE requires a deep understanding of the syllabus, consistent revision, structured answer writing, and smart test-taking strategies. The Prelims test analytical and conceptual clarity, the Mains focuses on critical thinking, articulation, and subject mastery, while the Interview assesses presence of mind, ethical judgment, and personality traits relevant to public service.
