Historic Samudrayaan mission and Matsya 6000 submersible: India heads for a deep sea dive

Samudrayaan Mission's Objective: The Samudrayaan Mission aims to create a self-propelled submersible capable of carrying three people to a depth of 6000 meters in the ocean. It's equipped with advanced scientific tools and sensors for deep-sea exploration, with a 12-hour operational period (96 hours in emergencies).

This manned submersible empowers scientists to directly observe and understand uncharted deep-sea regions, greatly enhancing India's capabilities in man-rated vehicle development.

Samudrayaan Timeline and cost: The projected timeline for Samudrayaan Mission spans from 2020-2021 to 2025-2026, backed by a government investment of Rs, 8000 crore for mining, investigating, and studying the ocean floor, according to a PIB data.

It employs human and unmanned submersibles to search for polymetallic nodules rich in minerals like manganese, nickel, cobalt, copper, and iron hydroxide, which are crucial for electronics and renewable energy.

In 1981, India initiated its quest for polymetallic nodules with the first sample collected from the Arabian Sea aboard the research vessel Gaveshani.

In 1987, India made history by becoming the first country to secure a 150,000 km2 region for nodule exploration in the Central Indian Ocean Basin. This exclusive rights grant was based on extensive surveys by CSIR-NIO scientists.

India's dedication to polymetallic nodules led to the signing of a contract with the International Seabed Authority (ISA) in 2002, followed by a resource appraisal. 

After surrendering 50 percent of the initial area, India retained an 18,000 square-kilometer 'First New gen Mine-site.'
