ISRO IS PLANNING TO LAUNCH SATELLITE ADITYA TO STUDY SUN

Science & Tech


Why in news?

Prime Minister Narendra Modi has said that ISRO is planning to launch a satellite called Aditya to study the sun. In his 'Mann ki Baat' programme of AIR, Mr Modi said, India is quite advanced in the field of astronomy and ISRO has taken path-breaking initiatives in this field.


Highlights:

  • The Prime Minister said that India has many powerful telescopes around the country including a giant meter-wave telescope near Pune and other powerful telescopes located in Kodaikkaanal, Udagamandala, Guru Shikhar and Hanle Ladakh.

  • The probe named Aditya-L1 will be sent by PSLV-XL from Sriharikota to observe the solar corona, the outer layers of the Sun.

  • Its main payload is Visible Emission Line Coronagraph (VELC) which will study the diagnostic parameters of solar corona and dynamics and origin of Coronal Mass Ejections (3 visible and 1 Infra-Red channels).

  • It will be inserted in a halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system, which is 1.5 million km from the Earth.

  • Significance of Mission:

  • A Satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has the major advantage of continuously viewing the Sun without any eclipses.

  • Only NASA and ESA have successfully placed satellites at the L1 point as of date.

  • This will be the first Indian space mission to study the Sun.

  • It will be India’s third big extra-terrestrial outing after Moon and Mars.

Lagrange Points:


A Lagrange point is a location in space where the combined gravitational forces of two large bodies, such as Earth and the sun or Earth and the moon, equal the centrifugal force felt by a much smaller third body.


The interaction of the forces creates a point of equilibrium where a spacecraft may be "parked" to make observations. These points are named after Joseph-Louis Lagrange, an 18th-century mathematician.


Structure of Lagrange points in sun-earth system:


There are five such points, labeled L1 to L5, all in the orbital plane of the two large bodies. The first three are on the line connecting the two large bodies; the last two, L4 and L5, each form an equilateral triangle with the two large bodies.


The two latter points are stable, which implies that objects can orbit around them in a rotating coordinate system tied to the two large bodies.

'WORLD ECONOMIC LEAGUE TABLE 2020'

Part of GS- 3 Economy


Why in news?

India will overtake Germany to become fourth-largest economy in the world by the year 2026. According to a report by the UK-based Centre for Economics and Business Research (CEBR), India is all set to overtake Japan to become the third-largest economy by 2034.


Highlights:

  • The report titled 'World Economic League Table 2020' said that India is also set to become a 5 trillion dollar economy by 2026, 2 years later than the government's target of 2024.

  • The World Economic League Table is an annual calculation by CEBR jointly published by CEBR and Global Construction Perspectives.

  • The base data for 2019 is taken from the IMF World Economic Outlook.

  • India has decisively overtaken both France and the UK to become the world's fifth-largest economy in 2019.

  • The report said that Japan, Germany and India will battle for third position over the next 15 years.

RATING SHOPPING

Part of GS- 3 Economy


Why in news?

Reserve Bank of India (RBI) has criticised Credit Rating Agencies (CRAs) for allowing low-rated companies to do "rating shopping".


Highlights:

  • According to RBI, Rating shopping refers to how, a company or a debt paper manages to get same or better rating from another agency within three months of it getting a poor rating.

  • Rating agencies have been largely blamed for their lax policies and oversight for the 2008 global financial crisis.

  • A fortnight before IL&FS went belly up in September 2018, rating agencies India Ratings, Icra and Care had given its debt papers AAA/AA+ ratings.

  • In the 25th edition of the Financial Stability Report, RBI has warned of 'rating shopping' by companies for long-term bank loans based on indicative ratings given by CRAs which are not available to the banks or investors.
