DRDO BMD Phase-II Tested: AD-1, AD-2 Interceptors, ICBM-Class Shield & NASM-MR Explained
On June 10 and 11, 2026, India's Defence Research and Development Organisation (DRDO) carried out three consecutive flight-tests off the Odisha coast that validated a multi-layered Ballistic Missile Defence (BMD) system and successfully conducted the maiden test of the Naval Anti-Ship Missile-Medium Range (NASM-MR). The Ministry of Defence said the interceptors engaged their targets up to the Intercontinental Ballistic Missile (ICBM) class, placing India among a small group of nations with such capability. This article explains India's BMD programme, the difference between the AD-1 and AD-2 interceptors, the science of endo- and exo-atmospheric interception, the significance of NASM-MR, and why this matters for India's strategic deterrence.
SMILE Mission Explained: How ESA-China Probe Will Image Earth's Magnetosphere & Decode the Solar Wind
In a first of its kind, the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS) launched the SMILE mission (Solar wind Magnetosphere Ionosphere Link Explorer) on 19 May 2026 aboard a Vega-C rocket to study Earth's magnetic shield against the Sun. SMILE will capture the first-ever X-ray images of the magnetosphere. This article explains the SMILE mission, Earth's magnetosphere, solar wind, geomagnetic storms, auroras, space weather, the four science instruments, the highly elliptical orbit, and how it links to India's Aditya-L1 — everything UPSC aspirants need on this landmark space-science mission.
ISRO's PSLV-C62 Mission Failure: Understanding Third-Stage Anomaly and Its Impact on India's Space Reliability
India's first space launch of 2026 ended in failure when the PSLV-C62 rocket, carrying 16 satellites including a key earth observation payload, deviated from its path due to a problem in the third stage. This marks the second straight failure for ISRO's trusted PSLV rocket in less than a year, raising questions about its dependability and affecting commercial and strategic goals.
ISRO's PSLV-C62 Mission Fails Due to Third Stage Issue: Understanding the Setback and Its Impact on India's Space Goals
India's first space mission of 2026 ended in failure when the PSLV-C62 rocket, launched from Sriharikota, deviated from its path due to a problem in the third stage. This led to the loss of 16 satellites, including the main earth observation satellite and international payloads, raising concerns about the reliability of ISRO's workhorse rocket just months after a similar failure in 2025.
Mission Sudarshan Chakra: Integrating Energy Weapons, Satellites, and Radar Networks for India's Nationwide Air Defence Shield
Recent details from defence sources reveal how Mission Sudarshan Chakra, announced by Prime Minister Narendra Modi on India's 79th Independence Day, will incorporate advanced components like directed energy weapons, satellites, and a vast radar network to create a multilayered air defence shield. This initiative aims to protect strategic and civilian sites from aerial threats, building on successful tests of indigenous systems and lessons from recent conflicts, highlighting India's push towards self-reliant defence technology amid evolving regional security challenges.
After Operation Sindoor: Indian Army Fast-Tracks Radar Upgrades to Shield Borders from Drone Swarms
The Indian Army has kicked off urgent procurement of advanced radars to strengthen its air defence against low-flying drones and swarms, learning key lessons from Operation Sindoor in May 2025. During this short border clash with Pakistan, hundreds of enemy drones slipped through older detection systems, pushing the Army to issue Requests for Information for up to 45 enhanced low-level radars and 48 fire control systems. This move aims to plug gaps along northern and western borders, boosting overall readiness in a time of rising aerial threats from neighbors.
Gaganyaan: ISRO Conducts Simulation Missions Ahead of India's First Human Spaceflight
The Indian Space Research Organisation (ISRO) has been conducting crucial simulation missions in Bengaluru using a static mock-up simulator to prepare astronaut-designates for India's maiden human spaceflight under the Gaganyaan programme. These simulations, allowing astronauts to experience spacecraft-like conditions for extended periods, are part of the final preparations ahead of the first uncrewed test flight (G1) scheduled for December 2025, featuring the humanoid robot Vyommitra. This development underscores India's push towards self-reliance in space exploration, with the crewed mission now targeted for 2027.
India Successfully Test-Fires Agni-5 Missile, Strengthens Strategic Deterrence
On August 20, 2025, India conducted a successful test-firing of its nuclear-capable Agni-5 intermediate-range ballistic missile (IRBM) from the Abdul Kalam Island off the Odisha coast. The test was carried out by the Strategic Forces Command (SFC) and validated all key operational and technical parameters, reinforcing India's long-range strike capabilities.
