Chandrayaan-3 Landing Site Composition Matches Antarctic Lunar Meteorite ALHA 81005: PRL Study

ISRO's Oceansat-3 Captures Sharp Drop in Pacific Marine Productivity as El Niño Warms Ocean

ISRO's Oceansat-3 satellite has detected a sharp decline in chlorophyll-a in the equatorial Pacific Ocean during April-June 2026, linked to the developing El Niño. This reduction in marine productivity threatens the ocean food chain and serves as an early climate indicator ahead of a forecast strong El Niño event from September 2026 to February 2027.

India's First Private Orbital Rocket Vikram-1 Launched July 18; Gaganyaan Parachute Test Qualified

India's first privately developed orbital rocket Vikram-1, built by Skyroot Aerospace, was successfully launched on July 18, 2026, from Sriharikota under 'Mission Aagaman', making India only the third country globally to achieve private orbital launch capability. The article also covers new IN-SPACe re-entry guidelines, Gaganyaan mission progress (SOLVE motor test, IMAT-05 parachute test, crew module qualification), and a Tracxn report revealing SpaceTech funding concentration. Critical for UPSC: space sector reforms, private participation, and ISRO's human spaceflight milestones.

ISRO Chairman Calls for Academia-Industry Partnership to Achieve Space Station by 2035, Moon Landing by 2040

ISRO Chairman V. Narayanan has called for a stronger academia-industry partnership to realise India's ambitious space goals, including an indigenous space station by 2035 and a manned Moon landing by 2040. The event, part of the ISRO Academia Connect initiative, highlights the need for application-oriented research and patents, moving beyond academic publications. This is crucial for aspirants tracking India's space programme and its growing self-reliance in critical technologies.

NASA Invites ISRO to Join Moon Base Program Under Artemis Accords for Lunar South Pole Outpost

NASA has formally invited ISRO to join its ambitious Moon Base programme, aiming to build humanity's first lunar outpost near the South Pole. This invitation, extended during the 9th India-U.S. Civil Space Joint Working Group meeting in Bengaluru, deepens bilateral space collaboration under the Artemis Accords and the TRUST initiative. For UPSC aspirants, this is a crucial topic for Science & Tech and International Relations, with potential prelims questions on the Artemis Accords, CSJWG, and lunar South Pole.

NASA Invites ISRO to Join Moon Base Programme; India Signed Artemis Accords, Targets 2040 Human Moon Landing

NASA has invited ISRO to join its Moon Base programme, a major step in India-US space cooperation. India, a signatory to the Artemis Accords, aims to land humans on the Moon by 2040. This collaboration offers ISRO hands-on experience but raises concerns about technology dependency.

India's Space Launch Cost Highest at $13,302/kg; Study Cites ISRO's Small Rocket Fleet & Infrequent Launches

A peer-reviewed study published in Economics Letters reveals that India's per-kilogram cost to send payload to low-earth orbit is the highest among major spacefaring nations at $13,302, contradicting its reputation for low-cost launches. The high cost is attributed to ISRO's reliance on small rockets and insufficient launch frequency, preventing economies of scale.

Western Himalaya Warming 7.18°C by 2100, Snow Loss Triple Under High Emissions: Study

A new study reveals that the Western Himalaya is warming faster than the central and eastern parts, with winter temperatures projected to rise by over 7°C by 2100 under high emissions. This will lead to severe snow loss, threatening water security for 1.5 billion people dependent on glacier-fed rivers like the Indus, Ganges, and Brahmaputra.

Climate Change Study: 0.01°C/yr Temp Rise, 3.97mm/yr Rain Decline in Nilgiri Biosphere Reserve

A study reveals that climate change is disrupting the phenology of forests in the Nilgiri Biosphere Reserve, with a 0.01°C annual temperature rise and 3.97 mm annual rainfall decline from 1950 to 2018, leading to altered growing seasons and threatening endemic species. This data is critical for understanding climate impacts on biodiversity hotspots, a recurring theme in UPSC environment and geography questions.
