The ‘Samudrayaan’ is a part of the Ministry of Earth Sciences’ pilot project for deep ocean mining for rare minerals.
The project proposes to send a submersible vehicle with three persons to a depth of about 6000 metres to carry out deep underwater studies. The project is undertaken by the National Institute of Ocean Technology (NIOT), Chennai in line with the ISRO’s ambitious ‘Gaganyaan’ mission of sending an astronaut to space by 2022. The Matsya shown in last pic is the crew module of Samudrayaan.
The indigenously developed vehicle is capable of crawling on the sea bed at a depth of six kilometre for 72 hours.
The project proposes to carry three persons in a submersible vehicle to a depth of 6000 metres under sea for various studies. Submarines go only about 200 metres.
