Indian GSLV rocket now taller, heavier
CHENNAI: India's geosynchronous satellite launch vehicle (GSLV), scheduled to blast off Monday with an advanced communication satellite (GSAT-5P), is now taller by two metres and heavier by four tonnes as compared to its standard configuration.
The Indian Space Research Organisation's standard configuration for the GSLV rocket is a height of 49 metres and 414 tonnes in weight at lift-off.
The rocket that would lift off Monday stands 51 metres tall and weighs 418 tonnes.
P.S. Veeraraghavan, director of the Vikram Sarabhai Space Centre , told IANS: "This time the fuel quantity for the cryogenic engine has increased and its thrust power has also gone up. The rocket will be carrying a heavier satellite (GSAT-5P) weighing 2,310 kg."
The Russian made cryogenic engine will be powered with 15.2 tonnes of fuel (liquid hydrogen as fuel and liquid oxygen as oxidizer), an increase of around three tonnes, and the engine's length has also increased.
The rocket has a bigger heat shield - four-metres in diameter and made of fibre reinforced plastic (FRP) - as compared to the standard configuration of 3.4-metre diameter made of aluminium alloy metal.
With the changes in rocket's configuration, necessary calibrations have been carried out in the rocket's navigational systems, control dynamics and aerodynamics so that the flight is smooth and the mission is successful, a source associated with ISRO told IANS.
Over the years, the carrying capacity of the GSLV has also increased -- from 1,530 kg in 2001 for GSAT-1 to 2,220 kg for GSAT-4 in April 2010.
The latest has a payload of 2,310 kg with 36 transponders -- an automatic receiver and transmitter of communication or broadcast signals. Successful launch of the satellite will take the agency's transponder capacity to around 235 from 200 in orbit now.

Indian, Russian scientists discuss rocket launch delay
Indian and Russian space scientists are discussing the remedial measures that need to be taken after a leak was detected in the cryogenic engine of a rocket that was to place an advanced communications satellite into orbit on Monday. The Indian Space Research Organisation (ISRO) on Sunday decided
to postpone the rocket's launch after it detected the leak in one of the valves of the Russian-made cryogenic engine during the pre-countdown mandatory tests even as the 51-metre tall rocket was on the launch pad.
The rocket, called the geosynchronous satellite launch vehicle (GSLV) was to carry GSAT-5P, an advanced communications satellite meant to retire an earlier one sent up in 1999 and ensure continuity of telecom, TV and weather services.
S Satish, a director at ISRO, said: "There is a small team of Russian experts at the rocket port whenever a rocket is flown with their cryogenic engine."
He said the Russians had supplied seven cryogenic engines, of which five were used in the earlier GSLV rockets.
The 29-hour countdown, planned to commence at 11.01 a.m. Sunday, was not authorised by the Launch Authorisation Board. The board met Sunday forenoon at the Sriharikota rocket launch centre to review the results of pre-countdown checks and decided against proceeding with the mission.
According to ISRO officials, the GSLV rocket has three stages. The first stage is fired by solid fuel and hugged by four strap-on motors fired by liquid fuel. The strap-on motors give additional thrust during the lift off and the initial phase of the rocket's flight.
The second stage/engine is fired by liquid fuel and the third and complex stage is the cryogenic engine powered by liquid hydrogen as fuel and liquid oxygen as oxidizer.
The solid fuel is cast ready while the liquid fuel is filled hours before the rocket's blast-off.
Sources close to ISRO told IANS that there are standard leak rates for valves. Only when this exceeds the minimum level are alarm bells sounded.
ISRO officials said that since the cryogenic engine is supplied by Russia, their expertise and consent will be obtained on how to plug the leak.
If at all the valve has to be replaced, then it has to be supplied by the Russians, the sources said.
"The components of Indian cryogenic engine are of varied specifications and will not fit the Russian made one. The Russians had supplied the seven cryogenic engines long ago," the source told IANS.
According to officials, dismantling of the cryogenic engine with the faulty valve and fitting the rocket with another one will take time.
"The new engine's systems have to be checked and it will take over a month to make it flight ready," a source said.
According to ISRO officials, a delay in the GSAT-5P launch will not affect any of its customers as the earlier satellite INSAT-2E is still operational.

India to launch advanced communications satellite Dec 25
Chennai, Dec 22 (IANS) With investigations into a leak in a rocket engine's valve providing satisfactory results Wednesday, the Indian Space Research Organisation (ISRO) will celebrate Christmas by launching an advanced communications satellite, an official.
'The test results are satisfactory and the rocket's launch is scheduled Dec 25. The launch countdown will begin 11 a.m. Friday,'
S. Satish, a director at ISRO, told IANS.
The rocket carrying the GSAT-5P satellite is expected to blast off from the second launch pad between 4 p.m.-4.15 p.m. Saturday.
The GSAT-5P is meant to retire the INSAT-2E satellite sent up in 1999 to ensure continuity of telecom, TV and weather services and was originally scheduled for Monday.
However, ISRO Sunday decided to postpone the launch of its geosynchronous satellite launch vehicle (GSLV) after it detected a leak in one of the valves of its Russian-made cryogenic engine.
The leak was detected during the pre-countdown tests, even as the 51-metre tall rocket was on the launch pad at Sriharikota, around 80 km from here.
ISRO officials had said some tests would be conducted Tuesday to gauge the extent of the valve leak. They said the tests and discussions with Russian scientists would go hand-in-hand at Sriharikota.
The Russians had supplied seven cryogenic engines, of which five were used in earlier GSLV launches.
Another ISRO official, speaking on condition of anonymity, told IANS that the tests took around 30 hours and involved filling of liquid oxygen to check the valve. The liquid oxygen had to be later drained. The rocket's ground systems had to be reconfigured for the tests.
The cryogenic engine is fired by liquid hydrogen as fuel and liquid oxygen as oxidizer.
According to the official, the valve leak was in the liquid oxygen system while all other valves were functioning well.
He said the tests started Tuesday at 4 a.m. and concluded at around 8 a.m. Wednesday.
'The activities undertaken were similar to the ones carried out for a regular rocket launch. Around 100 scientists and technologists were involved in tests,' he said.

India to launch advanced communications satellite Dec 25
Countdown begins for GSAT launch Saturday
Chennai, Dec 24 (IANS) The 30-hour countdown for the launch of advanced communication satellite GSAT-5P started 10.04 Friday morning at the Sriharikota rocket launch centre, about 80 km from Chennai, an official of the Indian Space Research Organisation (ISRO) said.
The Rs.125 crore (Rs.1.25 billion) GSAT-5P satellite weighing 2,130 kg will serve the needs of the telecommunication, televison and weather sectors. It will eventually retire the INSAT-2E satellite that was sent up in 1999.
If all goes well, the satellite will be blasted off Saturday afternoon.
The GSAT-5P satellite with a life span of over 13 years has 36 transponders - automatic receivers and transmitters for communication and broadcast of signals. Successful launch of GSAT-5P will take the agency's transponder capacity to about 235 from the 200 currently in the orbit.
'The geosynchronous satellite launch vehicle (GSLV) carrying GSAT-5P will blast off from the second launch pad at Satish Dhawan Space Centre Saturday evening at 4.04 p.m.,' S.Satish, an ISRO director, told IANS.
The GSLV rocket is 51 metres tall, weighs 418 tonnes and costs around Rs.175 crore (Rs.1.75 billion).
ISRO officials told IANS that the filling of liquid and cryogenic fuel will be carried out during the countdown till 30 minutes before the actual lift-off.
The GSLV rocket has three stages. The first stage is fired by solid fuel. The four strap-on motors give additional thrust during the lift-off and the initial phase of the rocket's flight.
The second stage is fired by liquid fuel. The third stage, more complex than the others, involves the cryogenic engine powered by liquid hydrogen as fuel and liquid oxygen as oxidiser.
The launch was originally scheduled last Monday, but was aborted Sunday a leak was detected in one of the valves of the Russian-made cryogenic engine. Later, tests ensured the stability of the valve and the ISRO gave the go-ahead for Saturday launch.
The ISRO currently has the following communication satellites in service - INSAT 2E, INSAT 3A, INSAT 3B, INSAT 3C, INSAT 3E, INSAT 4A, INSAT 4CR and INSAT 4B working at 50 percent capability, Satish said.
ISRO launched two major satellites in 2010 - communication satellite GSAT-4 and remote sensing satellite Cartosat-2. GSAT-4 launch failed after the rocket crashed into the Bay of Bengal while Cartosat-2 was placed successfully in the orbit.

India plans to launch 30 satellites in next decade
BANGALORE (PTI): India is mulling to launch at least 30 earth observation satellites in the next one decade, a senior official at the Department of Space (DoS) said Tuesday.
"We expect not less than 30 satellites," Director of the Hyderabad-based National Remote Sensing Centre (NRSC), under the DoS Dr V Jayaraman said.
NRSC is responsible for remote sensing, satellite data acquisition and processing, data dissemination, aerial remote sensing and decision support for disaster management.
In a plan already drawn up for the next ten years, Indian Space Research Organisation would launch a series of Resourcesat, Cartosat, ocean and atmospheric satellites. This would include Cartosat-3 with 30 cm resolution, he said.
"We will launch Resourcesat-2 in early February or ending January. It will be a replacement satellite for Resourcesat-1 which gives us 5.8 metres, 70 km multi-spectral data for the first time," Jayaraman told PTI.
He said ISRO was setting up an integrated multi-mission ground segment in Hyderabad at an investment of Rs 35 crore to Rs 40 crore which is expected to be operational in June next.
In this single ground station (segment), ISRO would be able to receive all the satellite data "making the (space) products in such a way that every day we will supply 1000 products to the users directly."
Now, NRSC is in a position to deliver space products within four-five days of receiving the data. This new ground segment would enable it to do it within 12 hours and supply "emergency products" within one hour.
Earlier, inaugurating a state-level conference on Karnataka State Geospatial Database, organised by the Karnataka State Remote Sensing Applications Centre, Jayaraman stressed that GIS (geographic information system) and remote sensing experts need to leverage the power of cloud computing.
