GS-3: Science & Technology (Space)
1. ISRO SpaDeX Mission: Autonomous Space Docking Technology for BAS & Chandrayaan-4
Context: The Indian Space Research Organisation (ISRO) completed final integrated simulation tests for its twin-satellite SpaDeX (Space Docking Experiment) mission, designed to demonstrate autonomous rendezvous, docking, and formation flying in Low Earth Orbit (LEO).
🔍 PIB Fact File: Specifications of SpaDeX Mission
| Feature Parameter | Mission Specification |
|---|---|
| Twin Spacecraft Architecture | Consists of two ~400 kg satellites: Chaser (Target Hunter) and Target (Passive Node) launched on a single PSLV. |
| Docking Mechanism | Indigenously built cone-and-latch electro-mechanical docking port with optical, laser (LiDAR), and video sensors for real-time distance alignment. |
| Critical Precursor To | 1. Bharatiya Antariksh Station (BAS) assembly (target 2035). 2. Chandrayaan-4 lunar sample return mission requiring orbital module docking. |
| In-Space Payload Transfer | Demonstrates autonomous power transmission and data bus linking across docked spacecraft interfaces. |
Key Exam Takeaways:
- Global Elite Club: Upon successful docking, India will become the 4th nation (after US, Russia, and China) to independently master autonomous space docking.
- Human Spaceflight (Gaganyaan) Utility: Essential for transferring crew modules and refueling station modules in orbit during multi-mission operations.
RRB Ops & Tech Focus
2. Kavach 4.0 Dual-Antenna RFID Tag Readers & Track Location Calibration
Context: Research Designs and Standards Organisation (RDSO) issued standard operating procedures for installing Dual-Antenna RFID Readers on locomotive undercarriages to ensure zero-error track distance measurement under Kavach 4.0.
⚙️ Technical Notes for RRB NTPC, JE & Section Controller
- Trackside RFID Tags: Heavy-duty passive RFID tags installed between sleeper ties at 1 km intervals and at signal approaches (865–867 MHz band).
- Loco Reader Architecture: Dual-redundant RFID reader antennas mounted on locomotive bogies read tag IDs at speeds up to 160 km/h to reset cumulative wheel odometry errors.
- Movement Authority (MA) Accuracy: Pinpoints locomotive location within ±1 meter, preventing false target distance braking inside loco cabs.
BPSC State Special
3. Bihar Kaimur Pumped Storage Hydro Project (1,200 MW): Off-Peak Grid Storage
Context: The Cabinet of Bihar approved the Detailed Project Report (DPR) for setting up the state’s first 1,200 MW Pumped Storage Hydroelectric Project in the Kaimur hills plateau region to solve peak-hour grid stability challenges.
🎯 High-Yield Points for BPSC Prelims & Mains
- Location & Capacity: 1,200 MW capacity project situated across upper and lower reservoirs in the Kaimur plateau (Rohtas-Kaimur region).
- Water Battery Concept: Uses surplus solar power generated during day hours to pump water to the upper reservoir, releasing it through hydro-turbines during evening peak demand.
- State Nodal Partner: Executed jointly by Bihar State Power Holding Company Limited (BSPHCL) and NHPC.
Banking & Economy
4. RBI Framework on Domestic Systemically Important Banks (D-SIBs) Bucket Updates
Context: The Reserve Bank of India (RBI) published its annual assessment of Domestic Systemically Important Banks (D-SIBs), maintaining State Bank of India (SBI), HDFC Bank, and ICICI Bank under systemic capital bucket mandates.
- “Too Big To Fail” Concept: D-SIBs are banks whose failure would cause significant disruption to the essential financial services and domestic economy.
- Additional CET-1 Requirements:
- SBI & HDFC Bank: Placed in higher buckets requiring an additional 0.60% Common Equity Tier 1 (CET-1) capital buffer.
- ICICI Bank: Requires an additional 0.20% CET-1 capital buffer.
- Assessment Criteria: Evaluated across 4 parameters: Size, Interconnectedness, Lack of Substitutability, and Complexity.
