Samudrayaan Mission (GS Paper 2 & 3)

 v  Context: Samudrayaan’ will be India’s expedition to a depth of 6,000 m in the Indian Ocean.

·       The Samundrayaan Mission is India’s first manned deep ocean mission.

·       The six components of the mission are:

  1. Development of deep-sea mining technologies and a manned submersible
  2. Creating ocean climate change advisory services and future climate models
  3. Innovations for deep-sea biodiversity exploration and conservation
  4. Deep-sea survey for potential multi-metal hydrothermal mineral sites
  5. Harnessing energy and freshwater from the ocean
  6. Establishing an advanced Marine Station for Ocean Biology

·       Launched in 2021, the Ministry of Earth Sciences (MoES) is the nodal ministry implementing it.



·       MATSYA 6000 is an indigenously built manned submersible under the Samudrayaan Mission.

·       Developed by NIOT, it is designed to carry three humans to a depth of 6000 m.

·       Aim: To comprehensively study deep-sea resources and marine biodiversity assessment.

With its launch, it will make India the sixth country (after the US, Russia, Japan, France, and China) to have a manned under-sea expedition beyond 5,000 m.

ð  National Institute of Ocean Technology (NIOT), Chennai, is an autonomous institute under MoES.

ð  A submarine is a self-propelled underwater vessel capable of independent operation for an extended period of time.

ð  A submersible is an underwater vehicle that needs to be transported and supported by a larger watercraft or platform. They are smaller and less capable than submarines but can be more versatile and specialised.
