Microsoft launches Edu-Cloud with aim to Make Learning Fun

Information technology giant, Microsoft has launched a cloud computing-based offering Edu-Cloud with an aim to Make Learning Fun.

It seeks to enhance digital learning and teaching in schools and higher education institutions in India through virtual learning platforms.

Edu-Cloud by with the help of cloud computing technology will create, deliver and manage educational content from any device, anywhere, anytime in order to make learning easy and fun.

It is expected, Edu-Cloud will benefit around 1 million teachers and 6 million students in over 1,500 institutes across India in next 18 months.

Initially the company will tie-up with the Hyderabad based Chaitanya group of educational institutions which will adopt Edu-Cloud for its teachers and students in its 80 schools.

Teachers and students of these schools will use Microsoft’s Windows-powered tablets in order to access rich, interactive and relevant content from cloud to make learning and teaching more engaging and productive.

ISRO successfully tests indigenous cryogenic engine with four-tonne capacity

Indian Space Research Organisation (ISRO) on 28 April 2015 successfully tested an indigenous cryogenic engine.

The powerful version of the cryogenic engine was tested successfully at ISRO’s propulsion complex at Mahendragiri in Tirunelveli district of Tamil Nadu. A team headed by Director D Karthikesan had led the testing.

This engine will allow launch vehicles to carry satellites of up to capacity of four tonnes in geostationary orbit. It will also give boost to India’s interplanetary probes and manned space missions.

Facts about cryogenic engine

  • A cryogenic engine is more efficient as it provides more thrust for every kilogram of propellant burnt.
  • Cryogenic fuels are extremely clean as they give out only water while burning. The engine uses liquid oxygen at -2530C and liquid hydrogen at -1830C
  • It can develop the thrust needed in the final state of the rocket to put satellites, weighing two tonnes or more, into a geosynchronous orbit.
  • It is essential to master this technology for any space power as launching heavier satellites requires cryogenic engines even in the lower stages of the rocket.
  • It will also make India self-reliant in sending heavier satellites to the required orbits and eliminate need of dependence on foreign launch vehicles.

It should be noted that India sixth spacefarer after US, Russia, the European Space Agency, China and Japan to develop a cryogenic engine.

Earlier in January 2015, India had successfully launched GSLV-D5, the first successful launch vehicle with an indigenous cryogenic engine. But it had capacity to launch satellites of up to two tonnes.
