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.

West Bengal: BJP holds protest against Sandeshkhali videos, TMC worker 'heckled'
Sandeshkhali (WB), May 12: BJP workers on Sunday demonstrated against the circulation of purported videos "to malign the image" of saffron party leaders in West Bengal's Sandeshkhali, and allegedly heckled the local TMC legislator for spreading "misinformation" over complaints of sexual abuse, lodged by women in the area.
They also beat up a local TMC activist in Sandeshkhali in North 24 Parganas district for allegedly being involved in "disseminating false information about atrocities on women" in the area.
Led by BJP's Basirhat Lok Sabha constituency candidate Rekha Patra, the protestors demonstrated in front of Sandeshkhali Police station, also demanding the release of a party activist arrested in a "false dacoity" case.
Patra accused police of "slapping trumped-up charges on BJP activists" in Sandeshkhali, while "turning a blind eye to the filming and circulation of fake videos" implicating her party leaders and women in the area.
A section of women protestors allegedly dragged the local TMC activist from a house and beat him up in the presence of the party's Sandeshkhali MLA Sukumar Mahata who was there for campaigning, a leader of the ruling party claimed.
As Mahata tried to intervene he was allegedly shoved by the protestors, he said.
Mahata blamed Patra and her supporters for "orchestrating" the attack on the local TMC activist, stating that the "BJP's gameplan to defame Bengal is clear before the people of the state".
"The BJP broke all precedents and tried to disrupt our campaign but we did not retaliate," he said.
A team of police personnel rushed to the spot and managed to rescue the TMC activist.
The riverine Sandeshkhali area — situated on the borders of the Sundarbans, about 100 kilometres from Kolkata — had been on the boil in February with protests over allegations of sexual abuse and land grab against now arrested TMC leader Shajahan Sheikh and his supporters.
In a purported video that surfaced from Sandeshkhali on Saturday night, a local BJP leader was heard saying that over 70 women had received Rs 2,000 each for taking part in protests against local TMC satrap Sheikh and his aides who were accused of sexual assault and land grab.
In the video, lasting over 45 minutes, a man resembling BJP's Sandeshkhali mandal president Gangadhar Kayal told this to the questioner.
It was Kayal who had earlier said in another purported clip, the first in a series in the past week, that the rape allegations were “staged”.
PTI did not independently verify the authenticity of the videos.
One of the women, who demonstrated outside the police station, denied the allegation, and said, "Were we protesting in February for money? The TMC are making false claims".
Patra, the BJP candidate for the Basirhat Lok Sabha seat, alleged that a saffron party worker in the area was "arrested on a false dacoity charge but many TMC activists, allegedly involved in atrocities on women, are roaming around freely".
Branding the BJP as a "violent" party, TMC spokesperson and state minister Shashi Panja said, "TMC poll campaigners are being attacked by BJP candidate from Basirhat, Rekha Patra, and her followers in Sandeshkhali after the conspiracy hatched by the BJP has come to light."
The incident of attack on the TMC activist and the party MLA took place on the day of Prime Minister Narendra Modi's visit to West Bengal and "possibly under his instruction", the state minister alleged.
BJP candidate for Baranagar assembly bypoll and party's spokesperson Sajal Ghosh said the incident reflected the simmering anger of people of Sandeshkhali against TMC.
"The assault on the TMC activist and manhandling of the local MLA is just a pointer. More such incidents may follow if the TMC does not stop bringing disgrace to the mothers and sisters of Sandeshkhali by releasing such fake videos," he said.
TMC's "diabolical gameplan" to deflect attention from the atrocities on women by its leaders in the area will backfire, Ghosh told reporters.
Patra, before being fielded by BJP, was at the forefront of the series of agitation by women in Sandeshkhali in February and March.
