Samudrayaan Mission
Context:
A crucial set of tests for Samudrayaan which is India's first manned submersible mission, has been delayed to mid-next year.
This is due to the pending procurement of syntactic foam cladding from France.
The initial shallow water dive to 500 metres, originally scheduled for December 2024, is now expected to take place around April next year.
About Samudrayaan:
The Samudrayaan Project is a significant component of India's Deep Ocean Mission, which was launched in September 2021 by the Ministry of Earth Sciences (MoES)
The Samudrayaan Project itself is centered around the development of MATSYA 6000, India’s first manned submersible capable of reaching depths of up to 6,000 meters in the ocean.
The mission is pivotal for India's future plans to explore and mine precious metals from the deep ocean.
The project is led by the National Institute of Ocean Technology (NIOT), Chennai, under the Ministry of Earth Sciences.
Scientific Exploration:
The Samudrayaan mission is a crucial step in exploring India's deep-sea resources, such as polymetallic nodules, minerals, and oceanic biodiversity.
As part of the Deep Ocean Mission, Ocean Mineral Explorer (OMe 6000), an Autonomous Underwater Vehicle (AUV), has been deployed for deep-sea mineral exploration.
In December 2022, it conducted exploration activities at a site in the Central Indian Ocean Basin, reaching a depth of 5,271 meters.
Key Components:
MATSYA 6000 manned submersible vehicle being developed for the mission.
Syntactic Foam:
This is a specialized material required to provide buoyancy to the submersible, allowing it to float.
It is currently being procured from France.
Titanium Hull:
The final mission will utilize a titanium sphere capable of withstanding the immense pressure at 6,000 metres.
This hull is being manufactured by the Indian Space Research Organisation (ISRO).
Current Status:
Scientists have built a steel replica of the submersible to serve as a simulator for preliminary tests.
Before the deep dive, this prototype must undergo a trial dive to 500 metres once fitted with the syntactic foam.
