A year of mixed fortunes for Indian space sector (2017 In Retrospect)
Chennai: The year 2017 could be said to be one of mixed fortunes for the Indian space agency as it launched the much-awaited four-tonne rocket Geosynchronous Satellite Launch Vehicle-Mk III (GSLV-Mk III); put into orbit 104 satellites in a single mission; sent up the South Asia Satellite; and also crossed the double century mark of launching foreign satellites.
With the size of earth observation satellites reducing and the future trend moving towards a constellation of small satellites rather than a large one, India's space agency is developing a smaller rocket that can carry satellites weighing up to 500 kg.
But on the negative side, India's long-due satellite navigation system (NavIC) faced serious problems with the atomic clocks in a couple of satellites developing problems.
The clocks are important to provide precise locational data.
The mission to put into orbit a replacement for the first of the seven navigation satellites didn't succeed as the lighter Polar Satellite Launch Vehicle (PSLV) failed in its mission.
The year also saw India taking steps towards opening up the sector for private players as the government sought comments on its Draft Space Activities Bill.
The Indian Space Research Organisation (ISRO) had a great start with a record satellite launch and good going for the major part of the year but wound up 2017 smarting after an unexpected disaster.
In February India set a world record in the number of satellites launched in a single mission by successfully putting into orbit 104 satellites, including the country's own Cartosat-2 earth observation satellite.
This was followed by the copy book-style launch of the South Asia Satellite, intended to serve "economic and developmental priorities" of South Asian nations, using its heavier GSLV-Mk II rocket.
In 2014, Prime Minister Narendra Modi tasked ISRO to develop a satellite for use by the SAARC countries. But Pakistan declined the use of an India-developed satellite.
One of the unique aspects of the South Asia Satellite is that ISRO decided to have electric power for it -- without cutting down on the volume of traditional on-board fuel -- to check its performance for use in future satellites.
In May, India scored a double success, launching its latest -- and heaviest so far -- 3,136 kg GSAT-19 communication satellite with its brand new and heaviest GSLV-Mk III with a cryogenic engine.
While Indian space scientists named the 640 tonne rocket "fat boy", the Telugu media nicknamed it "Bahubali" as, like the hero in the massively successful film lifts a heavy Lingam, it carried the heaviest satellite by an Indian rocket.
The month of June saw ISRO completing yet another multiple satellite launch, putting into orbit the Cartosat satellite, Nano satellite NIUSAT and 29 foreign satellites from 14 countries.
In the process, ISRO crossed the double century mark in launching foreign satellites. India started launching foreign satellites in 1999.
The June month also saw India adding GSAT-17 to its fleet of communication satellites after it was launched into orbit by the heavy-lift rocket Ariane 5 from Kourou in French Guiana.
And there ended the tale of ISRO's success for 2017.
The last day of August turned out to be a black Thursday for ISRO as it suffered a serious setback after its PSLV rocket failed to deliver India's navigation satellite in its intended orbit.
The 1,425 kg Indian Regional Navigation Satellite-1H (IRNSS-1H), got stuck inside the rocket's upper deck as the heat shield did not separate to let it out.
"The rocket heat shield didn't separate. The satellite is inside the heat shield," ISRO Chairman A.S. Kiran Kumar said.
"The PSLV rocket has been successful for the past several years. So, the question of design failure does not arise. It could be an issue of a failed component or a process quality issue," M.Y.S. Prasad, a former Director of the Satish Dhawan Space Centre, told IANS.
While the Failure Analysis Committee (FAC) is yet to come out with its report on the cause of PSLV's failure, K. Sivan, Director, Vikram Sarabhai Space Centre, told IANS that failure of the pyro elements could be the reason for the non-separation of the heat shield.
Normally, the heat shield would separate after on-board computers give the command to ignite the explosives. The explosives would then ignite and explode to separate the two parts of the heat shield joined by bolts.
He said ISRO is further tightening the allowable dispersion, or variance from the ideal performance parameter, for all the systems in the PSLV.
Meanwhile, Sivan said the preliminary design for the proposed small four-stage rocket that would weigh around 100 tonnes is ready and its feasibility study has also been conducted.
The first rocket would be ready in two years once the project gets the necessary approvals, he added.
The PSLV rocket has three variants weighing between 230 tonnes and 320 tonnes, with a carrying capacity ranging between 1,100 kg and 1,900 kg.
Looking forward to 2018, Sivan said it is going to be an eventful year with several launches, including the country's second Chandrayaan moon mission.
Sivan said ISRO will be launching a Cartosat satellite and several foreign satellites as piggy-back with the PSLV rocket some time in January 2018.
He said the country's heaviest communication satellite -- the GSAT 11, weighing over five tonnes -- would be launched next year by Arianespace's Ariane rocket.

Modi should leverage his ties with world leaders to de-escalate war in West Asia: Omar Abdullah
Jammu (PTI): Jammu and Kashmir Chief Minister Omar Abdullah on Monday said India can play a meaningful role in de-escalation in West Asia, given Prime Minister Narendra Modi's strong relations with the warring countries and their neighbours.
He said Pakistan was leveraging ties with Iran and the United States, and that any effort towards ending the war should be welcomed.
"As I said in the House (Assembly), we would like the war to end as soon as possible. The role that the prime minister can play may not be possible for anyone else because of his good relations with all these countries," Abdullah told reporters on the sidelines of a function here.
He, however, said any escalation would not be easy to manage.
"Any such move by US President Donald Trump, despite the long history of Iran resisting external domination, would not be easy," the chief minister said.
Asked about Pakistan mediating in the war, he said, "I will simply say that if any country can play a role in preventing this war, no one should have any objection to it."
He added, "I will repeat what I said … our prime minister has good and close relations with all countries — whether it is Israel, the United States, Iran, or the countries around Iran. If those relationships can be used to make some progress and help ease the situation, it would be a good thing."
Abdullah said attacks by terror groups like Lashkar-e-Taiba and Jaish-e-Mohammed in India, as suggested by a report from the United States, are not unlikely.
Meanwhile, he asserted that any efforts to end the war, be it from Pakistan, must not be resisted.
"Pakistan is using its good relations with Iran and the United States to its advantage, and it has done so. How can we object to that? If that angle helps in stopping the war, would you want them not to act and let the war continue? We want the war to stop. If any country can play a role in that, it should. And if we can play an even better role, then we should do so," he said.
On unemployment in J-K, the chief minister said the issue cannot be resolved overnight, and government jobs alone are not the solution.
He stressed the need to explore alternative avenues, highlighting the importance of Mission Yuva in promoting entrepreneurship.
"Mission Yuva provides not just funding but also support in preparing DPRs and post-startup assistance, such as marketing. In just nine months, distributing Rs 1,000 crore and approving numerous schemes is a significant achievement," he said.
Abdullah credited the coordination between the government and Jammu and Kashmir Bank for the scheme's progress.
