India’s Technical Leap and ISRO’s Commercial Success

27isroIn a landmark of commercial success ,ISRO on 16th December 2015, launched six Singaporean satellites. This was the first time when no Indian satellite was not on board. The launch was done with  Polar Satellite Launch Vehicle’s core alone (PSLV-CA) variant.

To further enhance its technical capability,, apart from launching the six foreign satellites, ISRO also tested the rocket’s fourth stage/engine’s ability to restart after it was cut off around 17 minutes into the flight.

Technically speaking, India was testing a multiple burn fuel stage/rocket engine for the first time.

The successful launch of the six Singaporean satellites have taken Isro’s total flights of foreign satellites to 57.

Last month, India also launched its communication satellite GSAT-15 using the Ariane rocket of the European space agency which takes the total number of satellite launches in 2015 to 21 (17 foreign, four Indian).

What is the world’s most vulnerable city?

maliMany cities are fighting a losing battle against the ravages of nature, but is it possible to identify the world’s most vulnerable metropolis? Natural events are notoriously hard to predict – but the prospects for Malé do look particularly grim. For even if its new sea wall continues to be effective, the islands around the Maldives capital are going to disappear before too long. And if they disappear, so does Malé’s raison d’etre.

Uneven geographies of openness and information

By Helen Pallett (University of East Anglia, UK)

Open access to information and data appears to be a cause which has found its moment, with governments, businesses, NGOs and academics queuing up to ratify open access commitments and extoll its virtues. It has variously been heralded as a means of rejuvenating democracy, reforming corrupt institutions, holding big business and business-dealings to account, improving the quality of scientific data available, removing academics from their ivory towers, and changing relationships between publishers, academic journals and authors.

These arguments for the opening up of data and information now seem uncontroversial and have few serious detractors. However, an emerging body of work demonstrates that to take the geographies of information seriously is to add a significant but often-overlooked angle on debates in academia and policy on open access and open data. This is what Mark Graham, Stefano De Sabbata and Matthew A. Zook have done…

Fog on NH91

Clicked from inside my Vehicle. There was dense fog on highway. Fog is ground level cloud and it was as I was going through clouds. It was 4AM and visibility was near zero. There should be some fog dispersing lights on highways. We should try to model our highways on best highways of the world. Radar satellite input can be a good way to provide way in fog also.

(People think we in government sector work less.We have to work sometimes on Sundays too and in a dismal infrastructure. 🙂  )
