A year of satisfactory space missions

Chennai: Nine
satellite launches, a policy for managing remote sensing data and
commissioning of the country's fastest supercomputer -- India's
space agency can look back at 2011 with a fair sense of
satisfaction, though the scrapping of a controversial spectrum
deal with a private company remains a blemish on its yearly report
card.
During 2011, the Indian Space and Research Organisation (ISRO)
launched eight satellites using its own rocket Polar Satellite
Launch Vehicle (PSLV) and one communication satellite GSAT-8
through Ariane 5 from Kourou, French Guiana.
Though launch of two more remote sensing satellites were announced
before the year-end, they did not happen.
However, the launch of Indo-French satellite Megha Tropiques to
study the tropical weather system made India only the second
nation in the world to launch such a space mission.
India's most successful rocket, the PSLV, exceeded a half century
of satellite launches when it slung four satellites into orbit in
October.
The PSLV rocket has now launched successfully 52 satellites out of
53 it carried -- majorly remote sensing/earth observation
satellites both Indian and foreign -- and has been a major revenue
earner for ISRO.
The one failure happened in 1993 when the satellite was not able
to reach its orbit.
During the year, ISRO also decided on a detailed relook of its
heavier rocket Geosynchronous Satellite Launch Vehicle (GSLV) to
carry communication satellites. This followed the loss of two
rockets and the satellites in 2010.
In order to augment the transponder capacity of Indian National
Satellite (Insat) system, ISRO launched two communication
satellites in 2011 - GSAT-8 and GSAT-12.
With these two launches, ISRO-owned transponder capacity went up
to 187, while it has leased 86 transponders. It is estimated there
is an unmet demand for 170 transponders.
Meanwhile, to increase the frequency of satellite launches and to
cash in on the international market for launching remote sensing
satellites, ISRO is mulling another space port while beefing up
the facilities at the existing launch site in Sriharikota, around
80 km from here.
"A feasibility study on building second space port like the one in
Sriharikota will be made during the 12th (Five Year) Plan
(2012-17) period. The study will look at the need, economics,
safety and other aspects," ISRO chairman K. Radhakrishnan said.
But the year also saw controversy engulf its deal with Devas
Multimedia Pvt Ltd.
As per the deal, ISRO's commercial arm Antrix Corporation was to
provide 70 MHz S-Band spectrum to Devas, which is into multimedia
services. Antrix would provide the spectrum by leasing out
transponders of two satellites to be built mainly for Devas
Multimedia.
But the Comptroller and Auditor General (CAG) estimated the loss
to the exchequer at an astounding Rs.2 lakh crore ($37 billion)
because of the agreement.
The centre later scrapped the controversial deal.
An ISRO official told IANS that the issue has now gone for
arbitration.
The year also saw the formulation of a Remote Sensing Data Policy
governing the modalities for managing, permitting
acquisition/dissemination of data generated by remote sensing or
earth observatory satellites.
In May, ISRO commissioned at Rs.14 crore country's fastest and its
second supercomputer at the Vikram Sarabhai Space Centre (VSSC) in
Thiruvananthapuram in Kerala.
The new machine will be used by Indian space scientists for
solving complex problems and studying computational fluid dynamics
of ISRO rockets.
The year also saw the first batch of graduates from ISRO's own
Indian Institute of Space Science and Technology inducted into
service.
Outside of ISRO but in the space sector, 2011 saw students of
Indian Institute of Technology-Kanpur (IIT-K), Anna University of
Chennai and SRM University located near here winning the US space
agency NASA's student competition in the foreign category -- the
Environmentally Responsible (Green) Aviation College Student
Challenge.
Additionally, IIT-K and SRM University launched their small
satellites-Jugnu and SRMSAT using the PSLV rocket during the year.
City-based Anna University is the first Indian university to have
fabricated a satellite -- Anusat -- in 2009.
