Dhawan II Engine

Skyroot Aerospace successfully test-fired 3D-printed engine ‘Dhawan-II’ for a record 200 seconds.

In 2021, Skyroot successfully tested India’s first privately developed fully Cryogenic rocket engine ‘Dhawan-I’ which will power Vikram-I.
‘Dhawan-II’ is a 3.5 Kilo Newton (kN) engine which is the successor of ‘Dhawan-I’ (1.0 kN).
The endurance test of ‘Dhawan-II’ was carried out at Solar Industries propulsion test facility in Nagpur.
The engine was developed by Skyroot Aerospace for its heavier vehicle, Vikram II.
The Dhawan-II cryogenic engine will be used as the upper stage of the updated version Vikram II.
Fully cryogenic engines are ideal for the upper stages of a rocket due to their higher specific impulse that enhances payload-carrying capabilities.
The cryogenic rocket engine uses 2 high-performance rocket fuels which require cryogenic temperatures (below -150° Celsius) for storage and operation.
Liquid Natural Gas (LNG) and Liquid Oxygen (LoX) are the 2 cryogenic rocket fuels.

Skyroot has named its cryogenic engine ‘Dhawan’ in honour of ISRO chairman Satish Dhawan, a key architect of India’s space programme.

A study has revealed that Prosopis chilensis is threatening to pulverise native vegetation in the Gulf of Mannar Biosphere Reserve (GoMBR).

Prosopis chilensis is a drought-resistant plant.
It is also commonly known as Chilean mesquite.
It is a small to medium-sized legume tree
Similarity - It is very similar to Prosopis Juliflora (known as Mesquite) in both genetic and physical features.
Spread - It is native to the arid regions of South American countries namely, Argentina, Bolivia, Chile, and Peru.
The species has migrated to Africa and naturalized in many African countries.
Threat - Prosopis chilensis is an alien invasive species in the 21 islands divided into the Tuticorin, Vembar, Kilakkarai, and Mandapam groups in the Gulf of Mannar Biosphere Reserve (GoMBR).
The invasiveness of this species and how they came to India is not known so far.
Corals, seagrass, and mangroves are among the 3 unique ecosystems present on the islands.
Like any invasive species on an island, Prosopis chilensis will slowly kill the native trees as well as the mangroves.
The GoMBR, India’s first marine biosphere reserve, is one of the important habitats for coastal birds migrating as far as the Arctic Circle.

Ladakh’s wood carving has been granted the Geographical Indication (GI) Tag.

Last year, the government granted GI Tag for Raktsey Karpo apricot of Ladakh, first ever GI tag for Ladakh.

Wood carving of Ladakh has been an aesthetically vibrant art form in the Ladakh region.
Ladakh's wood carving has been known for its intricate designs and unique patterns.
The designs are mostly inspired by Buddhist themes and motifs.
The wood carvings are made from local wood such as willow and apricot.
They are often used for decorating doors, windows, and other household items.
The most ubiquitous piece of furniture is the 'chokste', a low heighted wooden table.
The heavily ornamental carving is either simply polished, or is painted and then varnished.
The GI tag will make cultural traditions of Ladakh popular and benefit wood carving artisans of Ladakh.

Geographical Indication Tag

Geographic Indication (GI) is defined under Article-23 and 24 of the Trade-Related Aspects of Intellectual Property Rights (TRIPS) Agreement of the World Trade Organization (WTO).
India is a member of the WTO and thus enacted the Geographical Indications of Goods (Registration & Protection) Act, 1999 which came into force from 2003.
A geographical indication (GI) is a sign used on products that have a specific geographical origin and possess qualities or a reputation that are due to that origin.
The qualities, characteristics or reputation of the product should be essentially due to the place of origin.
The registration of a geographical indication is valid for a period of 10 years.
Darjeeling tea became the first GI tagged product in India.
