LVM3, the heaviest payload rocket of the Indian Space Research Organisation carrying 36 One Web
satellites on board, took off on Sunday from the second launch pad at the Satish Dhawan Space
Centre here.

Key Highlight 

In this mission, LVM3 would place 36 One Web Gen-1 satellites totalling about 5,805 kg into
a 450 km circular orbit with an inclination of 87.4 degrees.

About LVM3 Launch Vehicle –

  • GSLV MkIII is configured as a three stage vehicle with two solid strap-on motors, one liquid
    core stage and a high thrust cryogenic upper stage.</>
  • GSLV Mk-III (LVM3) is the new heavy lift launch vehicle of ISRO for achieving a 4000 kg
    spacecraft launching capability to GTO (Geosynchronous Transfer Orbit) in a cost effective

About One Web –

  • It is a space powered global communications network connecting governments business and
    Headquartered in London, One Web enables high-speed, low latency connectivity for
    governments, businesses, and communities everywhere around the world
  • OneWeb has partnered with NewSpace India Limited (NSIL), the commercial arm of the nati
    onal space agency Indian Space Research Organization (ISRO), to facilitate the launch.


One Web Constellation 


  • The One Web Constellation operates in LEO Polar Orbit.
  • Satellites arranged in 12 rings (orbital planes) with 49 satellites in each plane.
  • Satellites orbit the Earth every 109 minutes.
  • The earth rotates under the satellites, so they always fly over new places on the ground.


Types of Earth Orbit

 Geostationary orbit (GEO)

  • GEO is used by satellites that need to stay constantly above one particular place over Earth, such as telecommunication satellites.
  • In order to perfectly match Earth’s rotation, the speed of GEO satellites should be about 3 km per second at an altitude of 35 786 km. This is much farther from Earth’s surface compared to many satellites.

Low Earth Orbit

  • It is normally at an altitude of less than 1000 km but could be as low as 160 km above Earth.
  • It is also the orbit used for the International Space Station (ISS), as it is easier for astronauts to travel to and from it at a shorter distance.

Medium Earth orbit (MEO)

  • Medium Earth orbit comprises a wide range of orbits anywhere between LEO and GEO.
  • It is very commonly used by navigation satellites

About WPI and CPI

The WPI and CPI are two commonly used terms to determine inflation in the country.

WPI (Wholesale Price Index)

  • It measures changes in the prices of goods that wholesale businesses sell and exchange wholesale with other businesses.
  • It is published by the Office of the Economic Adviser,Department of Trade and Industry.
  • This is the most widely used measure of inflation in India.
  • The main criticism of the index is that the public does not buy the products at wholesale prices.
  • In 2017, the base year for WPI for All India was revised from 2004-05 to 2011-12.

CPI (Consumer Price Index)

  • It measures price changes from the perspective of retail buyers.
  • It is published by the Office for National Statistics (ONS).
  • The CPI calculates the price difference of goods and services such as food, medical care, education, electronics, etc. purchased by Indian consumers for their use.
  • It Include several subgroups, including food and beverages, fuel and lighting, housing and clothing, bedding and footwear.
  • The four types of CPIare:
    • CPI for Industrial Workers (IW)
    • CPI for agricultural labor (AL)
    • CPI for the rural labor force (RL)
    • CPI (rural/urban/combined)
  • Among them, the first three items are compiled by the Labor Office of the Ministry of Labor and Employment. 
  • The fourth is prepared by the National Statistics Office of the Ministry of Statistics and Program Implementation.
  • The base year of the CPI is 2012.
  • The Monetary Policy Committee (MPC) uses CPI data to control inflation.In April 2014, the Reserve Bank of India (RBI) adopted the CPI as its primary measure of inflation.

Ecommerce giant Amazon generated an estimated 321 million kilograms (709 million pounds) of plastic from packaging waste in 2021 alone. This is a result of billions of boxes it shipped to its customers globally, according to a December 2022 report by Oceana.


  • The ocean advocacy group notes that this is enough plastic to circle the Earth over 800 times as air
  • Amazon refuted Oceana’s claim, stating that it follows a science­based approach to reduce packaging waste, there is a lot left to be
  • A K.•based startup,claims to have developed a technology that could alter the state of plastics and make them biodegradable.
    • The company calls the process “biotransformation”.
    • It claims the technology would digest the plastic packaging waste naturally with the help of microbes and biodegrade the waste without leaving behind any



What is Biotransformation Technology?

  • Biotransformation technology ensure plastics that escape refuse streams are processed efficiently and broken
  • Plastics made using this technology are given a pre•programmed time during which the manufactured material looks and feels like conventional plastics without compromising on
  • Once the product expires and is exposed to the external environment, it self•destructs and biotransforms into bioavailable
  • This wax is then consumed by microorganisms, converting waste into water, CO2, and
  • It is the world’s first that ensures polyolefins fully biodegrade in an open environment causing no microplastics.

Why do we need it?

  • The country is generating 3.5 billion kgs of plastic waste annually and that the per capita plastic waste generation has doubled in the past five years.
  • Of this, a third comes from packaging
  • In 2019, plastic packaging waste from e•commerce firms was estimated at over a billion kilograms worldwide, according to


  • A joint research project noted that Amazon generated, nearly 210 million kgs (465 million pounds) of plastic from packaging waste in
  • They also estimated that up to 10 million kgs (22.44 million pounds) of Amazon’s plastic packaging ended up in the world’s freshwater and marine ecosystems as pollution in the same year.
  • Amazon India has now eliminated single•use plastics across its fulfilment
  • Flipkart has also done the same in 2021 across its supply



Where can this technology be used?

  • Food packaging and health care industries are the two prime sectors that could use this technology to reduce
    • The increase in cost is relatively small compared to conventional plastic that does not contain this

Is this being used in India?

  • Some well•known Indian firms in food and packaging industries deploy such technologies.
  • Within healthcare and pharma industries, this technology provides biodegradable solutions for non•woven hygiene products like diapers, sanitary napkins, facial pads, etc.

Are we heading in the right direction?

  • The Indian government has launched multiple initiatives to move the country towards They have introduced a plastic waste management gazette to help tackle the ever•growing plastic pollution caused by single•use plastics.
  • Last year, the government imposed a ban on single•use plastics to bring a stop to its use in the
  • The National Dashboard on Elimination of Single Use Plastic and Plastic Waste Management brings all stakeholders together to track the progress made in eliminating single•use plastic and effectively managing such
  • An Extended Producer Responsibility (EPR) portal helps in improving accountability traceability, and facilitating ease of compliance reporting in relation to EPR obligations of the producers, importers and brand•owners.
  • India has also developed a mobile app to report single use plastics grievances to check sale, usage or manufacturing of single use plastics in their

What are the alternatives to reducing plastic waste?

  • A switch to jute or paper•based packaging could potentially cut down plastic
  • This could also build sustainability within the paper industry, and save on the import bill on ethylene
  • The wooden packaging is yet another alternative, but that will make the packaging bulkier and increase
  • The Government of Tamil Nadu, in Chennai, organised a National Expo and Conference of Startups to raise awareness on alternatives to single•use
  • The alternatives showcased were made using coir, bagasse, rice and wheat bran, plant and agricultural residue, banana and areca leaves, jute and
