In News: India’s ‘Deep Ocean Mission’
GS- III >> Science & Technology >> Mission
About Deep Ocean Mission:
- The Deep Ocean Mission (DOM) is India’s ambitious program for underwater exploration and harnessing deep-sea resources.
- Six Pillars of DOM:
- Development of technologies for deep-sea mining and a crewed submersible to reach 6,000 meters in the ocean.
- Ocean climate change advisory services.
- Technological innovations for deep-sea biodiversity exploration and conservation.
- Deep-ocean survey and exploration for potential mineral sites.
- Harnessing energy and freshwater from the ocean.
- Establishment of an advanced Marine Station for Ocean Biology.
- The National Institute of Ocean Technology (NIOT) is responsible for developing indigenous technologies for deep-sea mining and a crewed submersible called ‘Matsya6000.’
- The design of Matsya6000 is complete, and it can accommodate a crew of three. It has been certified for operations up to 500 meters depth.
- India aims to mine polymetallic nodules from the central Indian Ocean bed, which includes valuable minerals like copper, manganese, nickel, and cobalt. NIOT has conducted successful deep-sea locomotion trials using the underwater mining system ‘Varaha’ at a depth of 5,270 meters.
- The mission aligns with India’s focus on the blue economy, designated as the sixth core objective for India’s growth in the ‘New India 2030’ document. It supports blue trade and manufacturing.
- The Deep Ocean Mission aligns with global initiatives for sustainable ocean resource management and contributes to India’s growth and technological advancements in the field of oceanography and marine sciences.

Kavach
GS- I >> Economy >> Railways
In News: Trains involved in accident not fitted with Kavach but have Vigilance Control Device, says Waltair Divisional Railway Manager
About KAVACH:
- The KAVACH is an indigenously developed Automatic Train Protection (ATP) system by the Research Design and Standards Organisation (RDSO) in collaboration with the Indian industry.
- It is a state-of-the-art electronic system with Safety Integrity Level-4 (SIL-4) standards. It is meant to provide protection by preventing trains to pass the signal at Red (which marks danger) and avoid collision.
- It activates the train’s braking system automatically if the driver fails to control the train as per speed restrictions.
- In addition, it prevents the collision between two locomotives equipped with functional Kavach systems. The system also relays SoS messages during emergency situations.
How does Kavach work on railway systems:
- The Traffic Collision Avoidance System (TCAS), with the help of equipment on board the locomotive and transmission towers at stations connected with Radio Frequency Identification (RFID) tags, helps in two-way communication between the station master and loco-pilot to convey any emergency message.
- The instrument panel inside the cabin helps the loco-pilot know about the signal in advance without visual sighting, and the permissible speeds to be maintained.
- If a red signal is jumped and two trains come face to face on the same line, the technology automatically takes over and applies sudden brakes.
- Additionally, the hooter activates by itself when approaching a level crossing which serves as a big boon to loco-pilots during fog conditions when visibility is low.
