Mission Surya – Day 2: Matsya 6000, Quantum Computing & SPADEX
Important UPSC prelims topics including Matsya 6000 deep-sea mission, quantum computing fundamentals, SPADEX space docking experiment, and Indian launch vehicles.
16 February 2026
Day 2 focuses on important science and technology developments including India’s deep ocean mission submersible Matsya 6000, the basics of quantum computing, and ISRO’s SPADEX space docking mission.
Core Concepts
Matsya 6000 is India's first indigenous manned deep-sea submersible developed by NIOT.
It can carry three scientists to depths of 6,000 metres under the Samudrayaan mission.
Quantum computing uses qubits instead of classical bits and operates using principles of superposition and entanglement.
SPADEX is ISRO’s space docking experiment demonstrating autonomous rendezvous and docking of satellites.
India became the 4th country after the US, Russia and China to demonstrate space docking capability.
Indian Launch Vehicles
• PSLV – India's reliable workhorse launch vehicle used for polar and interplanetary missions.
• GSLV – Used for launching satellites into Geosynchronous Transfer Orbit with cryogenic engines.
• LVM3 – Heavy lift launch vehicle used for Chandrayaan missions and Gaganyaan.
• SSLV – Small Satellite Launch Vehicle designed for low-cost launches.
• ASLV – Early experimental launch vehicle that preceded PSLV.
