Subject: Government Schemes
Context: Amid anger over middlemen, Bengal’s rice bowl keeps ear out for Delhi farmer protests.
Concept:
Pradhan Mantri Kisan Samman Nidhi:
- It is implemented as a central sector scheme by the Government of India.

8. ADITYA-L1 SUPPORT CENTRE (ASC)
Subject : Science & tech
Context : The Indian programme to study the Sun and the region between the Sun and the Earth from space – Aditya-L1 – is due to be launched next year.
Concept :
- It will carry seven payloads which have been developed by various institutions across the country. Once the mission is launched, there will be a need for a ground support centre to monitor and coordinate the work on its various payloads.
- This role will be played by the ARIES facility (short for Aryabhata Research Institute for observational Sciences) which is situated near Nainital.
- In January 2021, an agreement was signed to this effect based on the proposal submitted by the ARIES team. With about four to five personnel, this centre will come up at Haldawani, where ARIES is setting up a data centre also.
- The Aditya-L1 Support Centre (ASC) will provide training through regular workshops for the guest users. Apart from this, it will provide ready-to-use Python and Java apps for the satellite data and demos and handouts to facilitate the guest users.
Aditya L1 Mission
- Aditya L1 will be launched using the Polar Satellite Launch Vehicle (PSLV) XL with 7 payloads (instruments) on board.
- Aditya-L1 would be placed into a point in space known as the L1 Lagrange point.
- Aditya L1 will study the Sun’s corona (Visible and Near infrared rays), Sun’s photosphere (soft and hard X-ray), chromosphere (Ultra Violet ), solar emissions, solar winds and flares, and Coronal Mass Ejections (CMEs), and will carry out round-the-clock imaging of the Sun.
Subject : Geography

Subject : Environment
Context : The Tiki Formation in Madhya Pradesh, a treasure trove of vertebrate fossils, has now yielded a new species and two genera of cynodonts, small rat-like animals that lived about 220 million years ago.
Concept :
- The researchers from the Indian Institute of Technology Kharagpur, used scanning electron microscopy to study about 10 teeth samples collected from the village of Tihki in Shahdol District, Madhya Pradesh.
- The results showed that they had found a new species, and they named it Rewaconodonindicus, indicating India, the country it was discovered from.
- The team also identified two new genera from the area. The first was named Inditheriumfloris, after India and the Latin word therium meaning beast. As the teeth had a flower-shaped crown, it earned the species name floris.
- The second was named Tikiodoncromptoni, after Tiki Formation and Greek word odon meaning tooth. The species name is after paleontologist A.W. Crompton.

Concept :
- Stardust is formed by the material ejected from stars and carried by stellar winds, getting blown into interstellar space.
- The stellar wind is a flow of gas ejected from the upper atmosphere of a star.
- Interstellar space is defined as that which lies beyond a magnetic region that extends about 122 Astronomical Unit (AU) from the sun.
- During the solar system’s birth, this dust was incorporated into everything that formed including the planets and the sun but survived intact until now only in asteroids and comets.
