Green Propulsion Technology

 

Human Space Flight Mission of India Gaganyaan to be launched in December 2021.

Indian Space Research Organisation has developed a Green Propulsion Technology for Space Flight.

Propulsion Technology

Propulsion literally means to push forward or drive an object forward.

In rockets and airplanes, the principle behind the propulsion is application of Newton’s third law, “for every action, there is an equal and opposite reaction”. A Combustion of fuel releases hot exhaust and thus released mass of gas accelerates the engine.

Green Propulsion Technology of ISRO

  • ISRO began the journey of developing Green Propulsion Technology considering the environment and air pollution caused by burning fuels in 2018.
  • ISRO find an alternative to conventional liquid fuel that is an eco-friendly solid propellant Glycidyl Azide polymer GAP as fuel and Ammonium Di-Nitramide as oxidiser in 2018.
  • To test its innovation, ISRO had been carrying out technology demonstration projects which demonstrates the use of green propellant.
  • The combinations include Liquid Oxygen, kerosene, Hydrogen Peroxide, Glycerol-water and Methanol-water.
  • ISRO has already started using Green Propulsion Technologies in its mission.

However, the Green Propulsion Technologies are used only in part of the mission. For Example, the Liquid Hydrogen and Liquid Oxygen, combination of propulsion is already used in the Cryogenic Engines of upper stages of GSLV Mk-III launch vehicle. (India’s Indigenous Cryogenic Engine)

Cryogenic: Very low temperature processes such as air Liquefication

 At high altitude as the air is no longer present as oxidizer that the liquid oxygen (which is obtained by lowering temp to -150 degree centigrade involves the cryogenic process). The rocket avoids solid fuels as the liquid are meant for better control of combustion than solids.

  • ISRO has developed ISORENE.
  • ISORENE is rocket grade version of kerosene.
  • It is an alternative to conventional Hydrazine rocket fuel.
  • ISRO successfully demonstrated the Electric Propulsion system in its South Asia Satellite also known as SAARC satellite that was launched in May 2017.

South Asia Satellite

The South Asian satellite: GSAT-9.

The satellite is brainchild of ISRO, an initiative of India to provide services to SAARC region operated by ISRO.

The satellite serves Bangladesh, Sri Lanka, Nepal, Bhutan, Afghanistan and Maldives. Except Pakistan all other regional SAARC members are using its services.

Pakistan was wary of India initiative and stating that its concerns country national security did not participate in the programme.

However, Pakistan was ready to offer monetary and technical support to GSAT-9. However, India rejected the help stating it is not willing to develop the satellite on collaborative basis.

Pakistan has its own space programme under SUPARCO (Space and Upper Atmosphere Research Commission).

 

 

 

The Khadi and Village Industries Commission (KVIC)

 

Recently, the KVIC established the Monpa handmade paper making unit.

About the unit

To increase the commercial productivity of paper produced based on Monpa technique is the purpose of this unit.

Also, the unit will generate employment opportunities in Arunachal Pradesh.

Sunil Kothari Passes Away

 

Who was he?

Eminent Dance Scholar.

Key Points

He wrote extensively on BharatanatyamKathak and Manipuri dance forms and authored 20 books on Indian classical dances.

  • The fourth highest civilian award, Padma Shri,is conferred upon him in 2001.
  • His work, “Sattriya: Classical Dance of Assam” has special significance with respect to Assam Dance Form.
  • New Directions in Indian Danceand Kuchipudi Indian Classical Dance Art are his notable contributions.

Indian Classical Dances

  • The Indian classical dances have two basic concepts:

    • Tandava(movement and rhythm)
    • Lasya (grace, bhava and rasa).
  • Thethree main components of classical dance are:
    • Natya:the imitation of characters that is the dramatic element of the dance.
    • Nritta:the dance movements in their basic form.
    • Nritya: mudras or gestures that is expressional component.
  • The Natya Shastrawritten by Bharat Muni is unique and composite source for the Indian aestheticians for building the characteristics of the dances.
  • There are 8 classical dances in India:
    • Bharatnatyam (Tamil Nadu)
    • Kathak (North India)
    • Kathakali (Kerala)
    • Mohiniyattam (Kerala)
    • Kuchipudi (Andhra Pradesh)
    • Odissi (Odisha)
    • Sattriya (Assam)
    • Manipuri (Manipur)

Digital India Awards, 2020

 

The National Informatics Centre, Chief Minister Secretariat of Bihar and the Disaster Management Department have been jointly awarded Digital India Awards, 2020 in “Pandemic Category”.

Earlier the Digital India Award, 2020 under the “Excellence in Digital Governance” category was won by the Uttar Pradesh Food and Civil Supplies Department. It was selected for its Points of Sale based food distribution, online billing and payment for food grains purchased from farmers, GPS tracking of vehicles transporting food grains.

Key Highlights

Under the Pandemic Category Bihar was selected for its financial assistance to more than 21 lakhs of stranded workers outside Bihar. Through “Bihar Sahayata Mobile App” financial assistance was provided.

Rs 1000 were provided to workers coming from outside to Bihar and also to persons stuck in other states by the Bihar Government. Also financial assistance was provided to the workers of other states, who got stuck in Bihar due to COVID-19. To implement the initiative the Bihar Corona Sahayata Mobile App was used. The workers will have to simply register on the mobile app. The amount will be directly added to their account, once the verification of the workers was complete.
