Ever
since two consecutive failures of the giant GSLV rockets in 2010, (
A GSLV flight with an indigenous cryogenic engine failed in April
2010. The subsequent GSLV flight with a Russian cryogenic stage also
failed in December of that year.) Indian space research
organization (ISRO) have been stung with the failures and wants to
get over the old wound, as quickly as possible.
India
plans to launch an advanced communication satellite called GSAT-14,
weighing 1,980 kg, into orbit by means of a Geo-synchronous Satellite
Launch Vehicle (GSLV-D5) rocket around 5 PM on August 19 from
Sriharikota. Various checks showing that the vehicle is in the pink
of its health, the mood is one of optimism at the spaceport. This
rocket is powered by an indigenous cryogenic engine and Indian Space
Research Organisation (ISRO) have used every expertise available in
the country to ensure that the engine performs smoothly this time.
Earlier
this week, India achieved something that very few countries in the
world have achieved, as the reactor on board India’s first and
locally manufactured nuclear-powered submarine, 'Arihant', became
critical or went into operation at 1.20 AM on 10th
August 2013. This 111 metres long, 11 metres broad and about 15
metres tall submarine is designed to be propelled by a nuclear,
pressurised water reactor (PWR) that uses enriched uranium as fuel,
and light water as both coolant and moderator. The reactor is
designed to generate about 80 MW power. The scientists in charge of
the project say that the main challenge, was to make the reactor
compact enough to fit into a submarine. Besides, the reactor needs to
be stable when the submarine is accelerating in the depths of the
sea.

BBC's
defence and diplomatic correspondent, Jonathan Marcus, comments on
this significant achievement as
“ Previously,
only the established nuclear powers have operated ballistic
missile-carrying nuclear submarines - though it is not clear if
China's missile-carrying boats have actually ever been operationally
deployed. Israel too may have a limited sea-based deterrent
capability. The fact that this submarine, the nuclear reactor that
powers it, and the ballistic missiles that it will fire are all
manufactured locally in India - though there may have been some
assistance from Russia - is a significant technological achievement.
Once operational, the Arihant will mark a strategic milestone as
well. India's deployment of a nuclear triad - the capacity to launch
nuclear weapons from land, sea and air - will influence the strategic
calculations of other nuclear players in the region, Pakistan and
certainly China. An Indian sea-based deterrent will add a significant
new dimension to nuclear rivalries in the region.”
No
doubt, this is a super achievement and the scientists need to be
congratulated for this. Yet, within 2 days of this, another
breakthrough has come. On 12th
August 2013, India launched its first ever, locally built again,
aircraft carrier INS Vikrant. This 37000 tonne ship with a length
of 260m (850ft) and a breadth of 60m, has been built at the shipyard
in Cochin in South India. This launch marks the end of the first
phase of its construction and outfitting and further construction
would continue. INS Vikrant is expected to go for extensive trials in
2016 before being inducted into the navy by 2018. The ship has been
designed and manufactured locally and uses high grade steel made by
SAIL, Steel Authority of India, a state-owned steel company.
The
carrier would be able to carry 12 MiG-29Ks, eight Tejas light combat
aircraft and 10 early-warning and anti-submarine helicopters on its
2.5-acre flight deck and hangars. It is expected to have a crew of
160 officers and 1,400 sailors on board. The ship is powered by four
American LM2500 gas turbines manufactured by GE and is capable of
achieving speeds in excess of 28 knots. It is expected to have an
endurance of around 7,500 nautical miles at a speed of 18 knots.
With
these two significant achievements happening within a span of one
week, all eyes now are on the GSLV launch. ISRO officials remain
supremely confident about the success of the launch. S. Ramakrishnan,
Director of Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram
was asked whether the indigenous cryogenic engine would perform well
this time? This is what he had to say: “Of
course,” “We are doing well. We have done all the possible
tests. As of now, the [cryogenic] stage health is fine. All checks
show that the health of the vehicle is all right.”
M.C.
Dathan, Director of the Liquid Propulsion Systems Centre (LPSC), says
“we have made use of
every possible expertise available in the country to ensure that the
indigenous cryogenic engine performed flawlessly. This included
expertise from the academic institutions, and research and
development centres.”
So
would there be a hat trick of successes this week? Only time will
tell. Meanwhile all we can do is to wait with crossed fingers. But
nothing succeeds like success isn't it?

Never mind setbacks. Setbacks happen only when you try something big and new. I will ignore setbacks, and be happy that India is trying something new. I am also very happy to read about Arihant & Vikrant!!
ReplyDeleteI feel very proud and very happy when I hear good things about India. They should be publicized more aggressively to the world, instead of rapes and corruptions and poverty.
Jay Bharat!!!
