India’s Polar Satellite Launch Vehicle-C51 (PSLV-C51) rocket loaded with 19 satellites from Brazil, USA and India lifted off at 10.24 AM on February 28, 2021 from the Satish Dhawan Space Centre SHAR, Sriharikota (AP). After four stages of separation, the rocket launched Brazil’s 637-kilogram Amazonia 1 satellite, its primary passenger. Later after a gap of more than an hour it launched the remaining 18 passenger satellites. Amazonia-1 is the optical earth observation satellite of Brazil’s National Institute for Space Research (INPE). This satellite will provide remote sensing data to users for monitoring deforestation in the Amazon region and analysis of diversified agriculture across the Brazilian territory.

The discovery was significant in the field of physics as it gave proof of the quantum nature of light. It revolutionised multiple different domains of science and still forms the basis of varied applications in these fields. Every year India observes National Science Day on February 28 to commemorate the discovery of the ‘Raman Effect’ by physicist Sir Chandrasekhara Venkata Raman. It was on this day that the announcement regarding the discovery was made and which led to winning the Nobel Prize in physics. The Indian government also honoured Raman with the Bharat Ratna, the country’s highest civilian award.
Various programs are organised across the country to mark the National Science Day celebrations and motivate the students to opt for science as their career. Department of Science and Technology (DST also started the National Awards for Science Popularisation in February 1987 to recognise contribution in science through awards. The awards are given out on National Science Day under six categories.
This year, the government has decided "Future of STI: Impacts on Education, Skills, and Work" as the theme of this year's celebration.
Prime Minister Narendra Modi also spoke about the scientist in his monthly radio programme Mann Ki Baat and advised the youth of the country to read more about Indian scientists. "Today is National Science Day. It is dedicated to the discovery of the 'Raman Effect' by scientist Dr CV Raman. Our youth should read a lot about Indian scientists and understand the history of Indian science."
What is the 'Raman Effect’?
Raman Effect, also known as Raman Scattering, is the change in the wavelength of light that occurs when it is deflected by molecules. A light beam traversing through a transparent sample of a chemical compound sees a small fraction of the light emerging in a different direction to that of the incoming beam. A small part of that light has a differing wavelength from the incident light. This is because of the phenomenon known as Raman Effect.

A group of scientists of three institutes have discovered a new species of alpine plant in the Tawang district of Arunachal Pradesh. The details were published in Biodiversitas: Journal of Biological Diversity.
The plants that grow in the alpine climate. Many of the plant species and taxon grow as a plant community in such alpine tundra including perennial grasses, forbs, sedges, mosses, cushion plants and lichens. These plants are adapted to harsh alpine climatic of environmental conditions such as dryness, low temperatures, wind, drought, ultraviolet radiation, poor nutritional soil and a short growing season.
Typical weather for the regions that occurs above the tree line. It is also called as the mountain climate or highland climate.
It is the edge of habitat at which trees are capable to grow. Tree line is found at high elevations and high latitudes. It the line beyond which the trees cannot tolerate environmental conditions like extreme snowpack, cold temperatures, or associated lack of moisture.
It is the smallest districts out of the 16 administrative districts of Arunachal Pradesh. It has a population of 49,977 which makes the state as eighth least populous district in India. This district is inhabited by the Monpa people.
The National Institution for Transforming India (NITI Aayog) recently published its draft national policy on migrant labours.
This draft policy was formulated in the light of flaws in the existing laws. A report of 2017 also stated that the migrant workers should be integrated with all other workers so as to overarch the exploitation of workers by contractors. Further, in India the size of the unorganised sector is huge so a comprehensive policy was required to provide them a social protection.
