Project Samudrayaan


Source: TOI

 Context: Indian scientists are gearing up for an ambitious project called Samudrayaan, which involves sending three people 6,000 meters underwater in a domestically developed submersible named Matsya 6000.

  • This mission aims to explore the ocean depths of precious metals and minerals such as cobalt, nickel, and manganese.


About Matsya 6000:

Matsya 6000 has been in development for nearly two years and will undergo its first sea trials in the Bay of Bengal off the Chennai coast in early 2024. The submersible’s design has been reviewed carefully, taking into account materials, testing, certification, redundancy, and standard operating procedures.

The submersible’s design includes a 2.1-meter diameter sphere made of 80mm-thick titanium alloy, capable of withstanding the immense pressure at 6,000 meters depth, which is 600 times greater than sea level pressure. The vehicle is designed to operate continuously for 12 to 16 hours, with a 96-hour oxygen supply.


About Mission Samudrayaan:

  • The Samudrayaan mission is part of the Deep Ocean Mission, and sea trials at a depth of 500 meters are planned for the first quarter of 2024. The mission’s full realization is expected by 2026.
  • It’s worth noting that only a few countries, including the US, Russia, Japan, France, and China, have developed manned submersibles.
  • In addition to searching for valuable minerals like nickel, cobalt, and manganese, Matsya 6000 will investigate the chemosynthetic biodiversity in hydrothermal vents and low-temperature methane seeps in the ocean.
