Deep Ocean Mission & Samudrayaan
Samudrayaan is India's bid to put people on the deep-ocean floor: a crewed descent to 6,000 metres inside Matsya-6000, an indigenous titanium-sphere submersible built by NIOT under the Ministry of Earth Sciences' Deep Ocean Mission. Lok Sabha replies of 12 August 2026 set out where the seabed-mining half stands — exploration contracts with the International Seabed Authority covering nodules and sulphides, collection and crushing gear under development, and no commercial harvesting permitted yet — alongside about 19 biodiversity and fishery surveys of India's exclusive economic zone in three years. The mission's own new research ship, ORV Sagar Manthan, was launched at Kolkata on 9 September 2026.
