GSLV-D5 launch places India in elite league

One of India’s most ambitious dreams became a reality on Sunday when its Geosynchronous Satellite Launch Vehicle (GSLV-D5), powered by an indigenous cryogenic engine, effortlessly put the 1,982-kg GSAT-14 communication satellite into a perfect orbit after 17 minutes of flight.
The cryogenic engine built by the Indian Space Research Organisation (ISRO) fired for 12 of those 17 minutes.
The precision of the cryogenic upper stage was such that it put the GSAT-14 into an orbit with a perigee of 179 km, against the target of 180 km, and the apogee achieved was off by a mere 50 km for a target of 36,000 km.
The grand success caps 20 years of hard work by ISRO’s engineers, after being denied cryogenic technology under pressure from the U.S., suffering a heartbreaking failure with an indigenous cryogenic engine flight in April 2010 and having had to scrub its second attempt with an indigenous cryogenic engine in August 2013. “I am proud to say that ISRO has done it…,” ISRO Chairman K. Radhakrishnan announced at the end of the successful mission. “This is a big day for space technology in the country. This is a big achievement for the GSLV programme.”
The mission’s success means India now has the ability to put satellites weighing more than two tonnes in orbit, joining the elite club of the U.S., Russia and France.

Cloud seeding

Water is essential for life on the earth. Precipitation from the skies is the only source for it. India and the rest of Asia are dependent on the monsoons for rains. While the South West Monsoon is the main source for India as a whole, Tamil Nadu and coastal areas of South Andhra Pradesh get the benefit of the North East Monsoon, which is just a less dependable beat on the reversal of the South West Monsoon winds.

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”.

The Supreme Court on Friday came close to ordering the government not to deport the Rohingya.

It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests.

The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach it in …

India’s criminal wastage: over 10 million works under MGNREGA incomplete or abandoned (hindu)

In the last three and half years, the rate of work completion under the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) has drastically declined, leading to wastage of public money and leaving villages more prone to drought. This could also be a reason for people moving out of the programme.

At a time when more than one-third of India’s districts are reeling under a drought-like situation due to deficit rainfall, here comes another bad news. The works started under the MGNREGA—close to 80 per cent related to water conservation, irrigation and land development—are increasingly not being completed or in practice, abandoned.

Going by the data (as on October 12) in the Ministry of Rural Development’s website, which tracks progress of MGNREGA through a comprehensive MIS, 10.4 million works have not been completed since April 2014. In the last three and half years, 39.7 million works were started under the programme. Going by the stipulation under the programme, close to 7…
