Samudrayaan Mission

About

• Samudrayaan Mission is related to the ocean/sea.
• The Indian Government launched the Samudrayaan mission in October 2021.

Aim of the Mission

• It is aimed to develop "a self-propelled manned submersible to carry three human beings to a water depth of 6,000 meters in the ocean with a suite of scientific sensors and tools for deep ocean exploration.
• Developed indigenously, MATSYA 6000 is a manned submersible vehicle.
• It will facilitate the Ministry of Earth Sciences (MoES) in conducting deep ocean exploration.
• It has an endurance of 12 hours of operational period and 96 hours in case of emergency.
• The manned submersible will allow scientific personnel to observe and understand unexplored deep-sea areas by direct intervention.

Device for Samudrayaan misison:

• National Institute of Ocean Technology (NIOT), Chennai, an autonomous institute under the Ministry of Earth Sciences (MoES), has developed a 6000 m depth-rated Remotely Operated Vehicle (ROV) and various other underwater instruments.
• Some of the critical subsystems of the manned submersibles are the development of the Ti Alloy Personnel Sphere, Human support and safety system in enclosed space, low-density buoyancy modules, and Ballast and Trim System.

Relevance for India

• India has a unique maritime position, a 7517 km long coastline, which is home to nine coastal states and 1,382 islands.
• The mission aims to boost the Central government's vision of 'New India' that highlights the Blue Economy as one of the ten core dimensions of growth.
• For India, with its three sides surrounded by the oceans and around 30% of the nation's population living in coastal areas and coastal regions play a major economic factor. It supports fisheries and aquaculture, tourism, livelihoods, and blue trade.

Significance of the Mission

• This niche technology shall facilitate in carrying out deep ocean exploration of the non-living resources such as polymetallic manganese nodules, gas hydrates, hydro-thermal sulfides, and cobalt crusts, located at a depth between 1000 and 5500 meters.
