India is now set to launch 'Samudrayaan' - involving its first manned submersible called 'Matsya-6000' which will descend 6,000 metres into the Bay of Bengal with a three-man crew.

About Matsya-6000

  • It is a manned submersible vehicle developed by the National Institute of Ocean Technology (NIOT), Chennai. 
  • It was developed under the Samudrayaan mission to facilitate humans in the deep ocean in exploring mineral resources.
  • It would make India only one among six countries (US, Russia, Japan, France, and China) to have piloted a crewed under-sea expedition beyond 5,000 metres.
  • Objectives:
    • It will look at chemosynthetic biodiversity in hydrothermal vents and low-temperature methane seeps in the ocean.
    • It will also promote tourism and ocean literacy.
  • Features:
    • It is designed with the capability of operating in the deep sea for 12 hours, while in case of emergency, it can also operate up to 96 hours with all the necessary measures for human safety. 
    • Made of 80mm-thick titanium alloy, it will be able to withstand a pressure 600 times greater than that at sea level.
    • It relies only on gravity, water, and lithium-ion batteries for power.
    • It will also feature the ultra-short baseline acoustic positioning system (USBL). This will allow the mothership carrying the transponder to send information and the submersible to respond, which will then let the mothership know where the submersible is.
    • This is a flotation device that will rise to the top of the ocean — thus helping to find the submersible even in case it cannot resurface.


Key Facts about Samudrayaan Mission:

  • It is India’s first manned mission to explore the deep ocean. 
  • It is designed to study the deep ocean resources and conduct biodiversity assessments as well. 
  • The mission will not disturb the ecosystem as the submersible is used solely for exploration purposes. 
  • The project is part of the larger Deep Ocean Mission, which supports the Central Government’s Blue Economy policy.  
  • The Ministry of Earth Sciences (MoES) is the nodal ministry to implement this multi-institutional ambitious mission.


Q1) What is the Deep Ocean Mission?

It is a mission-mode project to support the Blue Economy Initiatives of the Government of India. It is a high-level multi-ministerial, multi-disciplinary programme for a better understanding of the deep sea living and non-living resources of the Indian Ocean. It will aid in India’s efforts to attain the Blue Economy status. It aims to develop technologies to harness living and non-living resources from the deep oceans. The Ministry of Earth Sciences (MoES) will be the nodal Ministry implementing this multi-institutional Mission.
