Official Question UPSC 2026

Which of the following statements with regard to India's Deep Ocean Mission is/are correct? 1. It was launched by the Ministry of Ports, Shipping and Waterways, Government of India. 2. Matsya-6000 has been designed to carry 3 people for deep sea exploration. 3. Samudrayaan is a project under this mission. Select the answer using the code given below:

Solution & Analysis

Answer: B
According to the Ministry of Earth Sciences (MoES) framework for marine development:
•Statement 1 is Incorrect: The Deep Ocean Mission (DOM) is a high-tech scientific initiative spearheaded explicitly by the Ministry of Earth Sciences (MoES), not the Ministry of Ports, Shipping and Waterways (which handles surface-level logistics and maritime transport).
•Statement 2 is Correct: Developed indigenously by NIOT, the Matsya-6000 is a specialized manned submersible. Encased in a titanium alloy sphere to withstand crushing pressure, it is designed to carry a crew of 3 aquanauts to a depth of 6,000 meters to study biodiversity and scout for polymetallic nodules.
•Statement 3 is Correct: The Samudrayaan initiative is India’s flagship manned deep-ocean exploration project and functions as the most high-profile sub-component directly under the overarching Deep Ocean Mission.
Conclusion: Statements 2 and 3 are correct, making Option B the right choice.

Examiner's Trap

The examiner uses a very common administrative distractor by swapping the highly scientific 'Ministry of Earth Sciences' with the more logistically focused 'Ministry of Ports, Shipping and Waterways', capitalizing on the nautical theme of the question.

Core Insight

At depths between 4,000 to 6,000 meters in the Central Indian Ocean Basin, the sea floor is rich in polymetallic nodules—potato-sized lumps containing extremely valuable minerals like cobalt, nickel, and copper, which are critical for electric vehicle batteries and advanced electronics.
