HYDERABAD,
India -- India's space program suffered a setback July 10 when a domestically
built rocket carrying a television broadcasting satellite failed shortly after
liftoff.
The
Geostationary Satellite Launch Vehicle (GSLV), which was making its second operational
flight, was ordered destroyed when it veered out of control 40 seconds after
lifting off from the Satish Dhawan Space Centre at Sriharikota. The launch
debris, including the $20 million Insat-4C communications satellite, fell into
the Bay of Bengal.
The mishap
occurred just one day after India's Agni-3 intermediate range ballistic
missile, designed to cover 3,500 kilometers, failed in its first test launch
due to a stage-separation glitch.
In
televised interviews, Gopalan Madhavan Nair, chairman of the Indian Space
Research Organisation (ISRO), said the exact cause of the GSLV mishap would be
known only after launch telemetry data are fully analyzed. But sources in ISRO,
who did not want to be named, said there appears to have been a problem with
one of the vehicle's four liquid-fueled strap-on boosters.
Nair said
the incident is "not a major setback" and that other space programs, including
India's lunar orbiter set for launch in early 2008 and any contracted
commercial launches, "will not be affected." In response to questioning, he
said mishaps in space programs are not unusual and noted that "even the space
shuttle" has had problems. "We too have to face such a problem and we will
solve it," Nair said.
At 2,180
kilograms, Insat-4C would have been the heaviest payload sent to space from
Indian soil. It is also the first of ISRO's Insat series of communications
satellites to be launched using the domestically produced GSLV. All previous
Insat satellites have been launched by American or European rockets.
Equipped
with 12 Ku-band transponders, Insat-4C was expected to boost direct-to home
television broadcasting in India.
In
addition, Sri Lanka's state-owned broadcaster Rupavahini had booked a capacity
aboard the satellite, becoming the first foreign client for Indian satellite
broadcasting services other than Intelsat, which has leased 11 Insat
transponders.
The GSLV
was declared operational after two developmental test flights conducted in
April 2001 and May 2003. The payloads on those missions were the 1,530-kilogram
GSat-1 and 1,825-kilogram GSat-2 experimental satellites, respectively.
In its
first operational flight in September 2004, the vehicle successfully launched
the 1,950-kilogram Edusat to support distance-learning programs.
The
three-stage GSLV stands 49 meters tall and weighs 414 tons. It has a
solid-fueled first stage augmented by four liquid-fueled strap-on boosters; a
liquid-fueled second stage and a cryogenic upper stage supplied by Russia.
