INDIA’S ‘DEEP OCEAN MISSION’ – SAMUDRAYAAN
- India’s flagship deep ocean mission, ‘Samudrayaan’, was initiated in 2021 by the Minister of Earth Sciences.
- It is India’s ambitious quest to explore and harness the depths of the ocean.
- India will embark on a journey to a depth of 6,000 metres in the ocean using an indigenously developed submersible with a three-member crew.
- It is chiefly implemented by the Ministry of Earth Science (MoES).
The mission has six pillars:
- Development of technologies for deep-sea mining and a manned submersible to carry three people to a depth of 6,000 metres in the ocean. The submersible will be equipped with a suite of scientific sensors, tools and an integrated system for mining polymetallic nodules from the central Indian Ocean;
- Development of ocean climate change advisory services, involving an array of ocean observations and models to understand and provide future climate projections;
- Technological innovations for the exploration and conservation of deep-sea biodiversity;
- Deep-ocean survey and exploration aimed at identifying potential sites of multi-metal hydrothermal sulphidesmineralisation along the Indian Ocean mid-oceanic ridges;
- Harnessing energy and freshwater from the ocean; and
- Establishing an advanced Marine Station for Ocean Biology, as a hub for nurturing talent and driving new opportunities in ocean biology and blue biotechnology.
Significance of Deep Ocean Mission:
- The ‘New India 2030’ document outlines a blue economy as the sixth core objective for India’s growth. The years 2021-2030 have been designated by the United Nations as the ‘Decade of Ocean Science’.
- DOM is one of nine missions under the Prime Minister’s Science, Technology, and Innovation Advisory Council(PMSTIAC). DOM supports the blue-economy priority area, blue trade, and blue manufacturing in India.
- The NIOT, an autonomous institute under MoES, has been entrusted with the development of ndigenous technologies to address engineering challenges associated with exploring and utilising oceanic resources.
- As a part of DOM,
- In ‘Samudrayaan’, India is embarking on a groundbreaking crewed expedition to reach the ocean bed at a depth of 6,000 m in the central Indian Ocean.
- It will be accomplished by Matsya6000, a deep-ocean submersible designed to accommodate a crew of three members.
- It is equipped with a suite of scientific sensors and tools.
- It has an operational endurance of 12 hours, which is extendable to 96 hours in the event of an emergency.
- It is also working on an integrated system to mine polymetallic nodules of precious minerals from the central Indian Ocean bed.
- NIOT has successfully conducted deep-sea locomotion trials on the seabed at a depth of 5,270 m using our underwater mining system, ‘Varaha’.
- This milestone is a step towards future exploration and harvesting of deep-sea resources.
- India has committed to the sustainable extraction of valuable resources, including polymetallic nodules and polymetallic sulphides.
- Polymetallic nodules contain precious metals like copper, manganese, nickel, iron, and cobalt, are found approximately 5,000 m deep, and polymetallic sulphides occur at around 3,000 m in the central Indian Ocean.
- The Matsya6000 is India’s flagship deep-ocean human submersible.
- The primary mission of Matsya6000 is exploration.
- It aims to reach the ocean bed at a depth of 6,000 m.
- It is accompanied by three crew members.
- The submersible carries a suite of scientific tools and equipment designed to facilitate observations, sample collection, basic video and audio recording, and experimentation.
- Constructed from a titanium alloy, the sphere is engineered to withstand pressures of up to 6,000 bar.
- It is equipped with propellers enabling movement in all six directions.
- It features three viewports that allow the crew to observe its surroundings.
- There will be about 12 cameras and 16 lights powered by lithium polymer batteries with an energy budget of 1 kWh.
- Communication will be through an acoustic phone and modem.
- The dimensions of Matsya are 9 m (l), 3 m (b), and 5 m (h).
- It will function as a free-floating system, for energy efficiency.
- It can move at a speed of about 5.5 km/hr using underwater thrusters.
Deep Ocean Mission by other Countries:
- The U.S.A, Russia, China, France, and Japan have already achieved successful deep-ocean crewed missions.
- It is aligned with the vision of ‘Atmanirbhar Bharat’.

ASIAN PARA GAMES 2023 MEDAL TALLY
- India finished the Asian Para Games 2023 with a best-ever medal tally of 111 medals – 29 gold, 31 silver and 51 bronze. It was held in Hangzhou, the People’s Republic of China.
- This was India’s best-ever medal tally at the continental meet, surpassing the previous record haul of 72 medals, including 15 gold, from the 2018 Asian Para Games.
- India had sent its 303 athletes – 191 men and 112 women – to the fourth edition of the Asian Para Games held in Hangzhou from from October 22 to 28.
- It the country’s largest contingent to the continental event. At the 2018 Asian Para Games, India had sent 190 athletes.
- India finished fifth on the Asian Para Games 2023.
- It was behind China, Iran, Japan and the Republic of Korea. China won 521 medals.

INDIA’S FISCAL DEFICIT
Why is in news?
- India’s fiscal deficit for the first half of the fiscal year 2023 (ending in September) was 7.02 lakh crore rupees.
- It is equivalent to 39.3% of annual estimates.
- The government aims to reduce the fiscal gap to 5.9% of GDP from 6.4% in the previous financial year.
About Fiscal deficit:
- Fiscal deficit is the difference between the government’s total expenditure and its total revenue (excluding borrowings).
- It is an indicator of the extent to which the government must borrow in order to finance its operations and is expressed as a percentage of the country’s GDP.
‘ONE NATION, ONE REGISTRATION PLATFORM’
- The National Medical Commission (NMC) is the regulatory body for medical education and medical professionals.
- It is all set to launch its “one nation, one registration platform” for doctors across the country.
- It is set to eliminate duplication and red tape and allow the public to access information on any physician working in India.
- The idea is to provide an ID to undergraduate students on the National Medical Register (NMR).
- This ID can be used to update any further qualification.
- The data of nearly 14 lakh doctors in the system will be transferred to the NMR.
