Offshore mining and mineral auctions
GS Paper - 2 (Polity)
In a significant step toward exploiting India's offshore resources, the Council of States passed the Offshore Areas Mineral (Development and Regulation) Amendment Bill (OAMDR), 2023. The Bill represents a transformative change for the offshore mining sector, which has remained largely inactive since the enactment of the OAMDR Act in 2002.
More about the Bill
It aims to increase transparency in the allocation of minerals found in the country's offshore basins, permitting the granting of production leases exclusively through auctions and reserving some allocations for government entities and public sector units (PSUs).
The passage of the Bill marks a historic milestone, unlocking India's vast mineral-rich offshore areas.
This move promises strategic benefits, strengthening the nation's territorial waters, which have been frequently threatened by neighboring countries.
The extraction of minerals from these areas is expected to bolster India's strategic position further.
Auctions as primary means
The Bill stipulates a fixed 50-year production lease for offshore minerals. Under this new legislation, the government plans to introduce auctions as the primary means to award production leases for offshore minerals.
The amendment enables the granting of production leases to the private sector solely through competitive bidding auctions.
Under the composite licensing system, explorers will also have the right to develop and mine minerals under a single license.
The Bill introduces a four-year timeline for the start of production and dispatch following the execution of a composite license or production lease.
It also establishes a two-year timeline (extendable by one year) for the resumption of production and dispatch after a discontinuation.

Chandrayaan enters moon orbit
GS Paper - 3 (Space Technology)
TWENTY-THREE days after it left earth, Chandrayaan-3, aiming to become the first Indian spacecraft to make a soft landing on the moon, entered lunar orbit, completing another milestone in its journey. This means that the spacecraft which had been moving towards the moon for the last five days — since it emerged out of its earth-bound orbit — has now begun to circle around the moon.
More about the Mission
MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity, said ISRO, putting words to what must only be an electronic signal from the spacecraft to the Mission Operations Complex (MOX) at the ISRO Telemetry, Tracking and Command Network (ISTRAC).
As of now, the spacecraft is in an elliptical orbit around the moon, that is 18,074 km from the lunar surface at its farthest and 164 km at the nearest.
This orbit altitude would be lowered progressively over the next few days, ultimately achieving a circular orbit of 100 km x 100 km, from which a final descent on the lunar surface is planned around 23 August 2023.
This is the third time that an Indian spacecraft has entered lunar orbit. The previous two Chandrayaan missions had also reached this phase.
Flashback
Chandrayaan-1 was only meant to be an orbiter, it did send out an instrument called Moon Impact Probe to crash land on the lunar surface.
Chandrayaan-2 was supposed to make a soft landing but could not, faltering in the last few seconds of its journey.
Chandrayaan-3 has taken slightly less time to reach the lunar orbit compared to Chandrayaan-2, which reached this destination in 30 days. But Chandrayaan-3 will spend more time in the lunar orbit, before attempting the soft landing.
If the soft landing is successful, it will make India the fourth country in the world to do so after the US, Russia and China.
Chandrayaan-3 is attempting to become the first mission to land near the lunar south pole. Other missions have so far landed close to the moon’s equator.

Chandrayaan-3 confirms Sulphur in lunar surface
GS Paper - 3 (Space Technology)
The Indian Space Research Organisation (ISRO) said the Pragyan rover's Laser-Induced Breakdown Spectroscope confirmed the presence of sulphur in the lunar surface near the south pole, through the first-ever in-situ measurements. Pragyan is a lunar rover that forms part of Chandrayaan-3, the lunar mission developed by ISRO.
More about discovery
The Laser-Induced Breakdown Spectroscopy (LIBS) instrument onboard Chandrayaan-3 Rover has made the first-ever in-situ measurements on the elemental composition of the lunar surface near the South Pole.
These in-situ measurements confirm the presence of sulphur (S) in the region unambiguously, something that was not feasible by the instruments onboard the orbiters.
LIBS is a scientific technique that analyses the composition of materials by exposing them to intense laser pulses.
A high-energy laser pulse is focused onto the surface of a material, such as a rock or soil. The laser pulse generates extremely hot and localised plasma.
The collected plasma light is spectrally resolved and detected by detectors such as Charge Coupled Devices. Since each element emits a characteristic set of wavelengths of light when it is in a plasma state, the elemental composition of the material is determined.
Chandrayaan-3 successfully executed a soft landing on the moon on 23 August 2023, making India the fourth nation in the world to achieve a successful lunar landing.
India also marked a milestone by becoming the first country to land near the South Pole, an area believed to harbour significant amounts of water ice.
ISRO on 29 August 2023 said preliminary analyses, graphically represented, have unveiled the presence of aluminium (Al), sulphur (S), calcium (Ca), iron (Fe), chromium (Cr), and titanium (Ti) on the lunar surface.
Further measurements have revealed the presence of manganese (Mn), silicon (Si), and oxygen (O). A thorough investigation regarding the presence of hydrogen is underway.
Flashback
The LIBS instrument is developed at the Laboratory for Electro-Optics Systems (LEOS) / ISRO, Bengaluru.
LEOS, situated at Peenya Industrial Estate, Bengaluru, is one of the vital units of ISRO.
It deals with the design, development, and production of attitude sensors for all low Earth orbit (LEO), geostationary Earth orbit (GEO) and interplanetary missions.
It develops and delivers optical systems for remote sensing and meteorological payloads.

Genome secrets of Indian oil sardine
GS Paper - 3 (Biotechnology)
In a major breakthrough in marine fisheries research, a team of scientists at the ICAR-Central Marine Fisheries Research Institute (CMFRI) has decoded the whole genome of the Indian oil sardine, a popular food fish. This is the first time that the genome of a marine fish species from the Indian subcontinent has been decoded, a CMFRI statement said.
More about the News
This development is a 'milestone' in Indian marine fisheries, the decoded genome will be a valuable resource for understanding the biology, ecology and evolution of the oil sardine (Sardinella longiceps).
This critical genome data could be used to improve the management strategies for the conservation and sustainable utilisation of this fish.
The decoded genome is 1.077 Gb in size and contains a total of 46316 protein coding genes.
This landmark research accomplishment was achieved through the cutting-edge Next Generation Sequencing technology by a group of researchers led by Dr Sandhya Sukumaran, Principal Scientist at Marine Biotechnology division of the CMFRI. This research has been published in the high-impact journal Scientific Data of the Nature Group.
Indian oil sardine is a vital fisheries resource in the Indian subcontinent, contributing substantially, approximately 10 per cent, to the total marine fisheries industry in India.
This fish is a trans-boundary resource and the whole genome information can also be utilised for certification of the fishery and identification of the origin of catch for monitoring clandestine trade and tracking the movement of this enigmatic fish.
Small pelagic fishes like the Indian oil sardines can be considered as model organisms to study the climatic as well as fishing impacts on the Indian Ocean resources, as they respond to variations in environmental and oceanographic parameters.
About Sardines
Sardines are an ecologically important part of the marine ecosystem, as they form an intermediate link in the food web and serve as prey for larger predators.
The genome assembly of the sardines is a valuable tool for studying how fish adapt to climate change.
Genetic and genomic investigations found that Indian oil sardines exist in two highly distinct stocks, one in Indian waters and another in the Gulf of Oman.
Understanding these genetic differences could help researchers comprehend how environmental and oceanographic conditions impact this species in different regions of the Northern Indian Ocean.
The CMFRI statement said the researchers have also identified the genes involved in the biosynthesis of polyunsaturated fatty acids (PUFA) of the oil sardine, offering insights into the genomic mechanisms behind the high nutritional quality of these sardines.
Oil sardines are a good source of these fatty acids, which play a crucial role in maintaining human health.
