GSLV to launch GSAT–14 during mid-2012[/size]

The Indian Space Research Organisation, which has planned to put three satellites into the orbit with its Polar Satellite Launch Vehicle before end of this year, will send its GSAT -14 with its indigenously developed Geosynchronous Satellite Launch Vehicle D-5 during mid-2012, Chairman, ISRO, K. Radhakrishnan has informed.

Speaking to reporters after inaugurating the two-day national conference on 'Expanding frontiers in propulsion technology' at Liquid Propulsion Systems Centre (LPSC) in Mahendragiri in the district on Friday, Dr. Radhakrishnan said the ISRO, which had learnt a lot of highly valuable lessons from the unsuccessful flight of GSLV D-3 in April 2010, was working hard on the rectifying the problems to make the GSLV D-5 flight a resounding victory. GSAT–14 satellite would have C-band communication transponders.

Towards achieving self-reliance in the development of the Mark III engine for GSLV, the S-200 solid propellant motor would be subjected to static test, which would be the repeat of the successful test that was conducted in January 2010.

Moreover, the ISRO has planned to launch GSAT – 12, which will have extended C-band transponders, with its Polar Satellite Launch Vehicle during next month.

After launching Meghatropique satellite, an Indo – French joint venture, in September 2011, the ISRO will be concentrating on the launching of Microwave Remote Sensing Satellite – RISAT – 1 – during December this year.

"Our PSLVs will launch these satellites that will provide us clear and excellent pictures even though the sky is overcast," Dr. Radhakrishnan said.

According to the ISRO chief, his prestigious testing centre at Mahendragiri had been adorned with one more most-modern facility – Thrust Chamber Test Facility – for testing the GSLV Mark III engine's cryogenic stage. "It will be ready for commissioning within next 60 days".

Inaugurating the conference, Dr. Radhakrishnan stressed the need for engaging more private firms with adequate and state-of-the-art research and development facilities in ISRO's missions and the leading educational institutions as is being done in the United States and Russia.

He stressed the need for developing non-chemical, electro and ionic propellants, "which will have longer life and propel the satellite in its orbit for more period."

Releasing the conference proceedings, Sathish Dhawan Space Centre Director M.C. Dathan hoped that the ISRO, with its highly committed and enthusiastic young workforce, would scale greater heights in the days to come.

Vikram Sarabhai Space Centre Director P.S. Veeraraghavan said due importance should be given for developing eco-friendly 'green propellants' and for launching a payload with nuclear fission.

LPSC Director S. Ramakrishnan delivered the keynote address on 'Expanding frontiers in propulsion technology'. Former LPSC director AE. Muthunayagam and Aeronautical Society of India secretary general Ashok Bhushan offered felicitations.

India's 2011-2012 Space Calendar: Four Launches To Look Forward To[/size]

By Srinivas Laxman
June 20, 2011

AsianScientist (Jun. 20, 2011) – The next twelve months promises to be an exciting time in India. It will see four satellite launches – a record of sorts for the country's space program.


July 2011 GSat-12 launch

Weather permitting and if everything else is a 'go', a 1,375 kg communication satellite of the Indian Space Research Organisation (ISRO) designated as GSat-12 will be launched in the second week of July.

GSat-12 will be ferried to its geosynchronous transfer orbit (GTO) by the highly-proven four-stage Polar Satellite Launch Vehicle (PSLV). Ultimately it will be placed in geosynchronous orbit at an altitude of 36,000 km.

ISRO chief spokesperson, S. Satish, told AsianScientist on Monday that the launch campaign has been initiated at the Satish Dhawan Space Centre, Sriharikota, and the satellite was already at the space complex undergoing the final series of tests. Satish said that the exact date for the launch will be firmed up in the next few days.

The satellite will be taken by the PSLV instead of the three-stage Geosynchronous Satellite Launch Vehicle (GSLV), due to current technical problems with the GSLV, and also the satellite's heavy weight (the PSLV has the capacity to carry satellites weighing up to 1440 kg).

Putting a satellite into orbit calls for additional effort from the rocket, since it needs to impart almost 40 percent extra velocity to the spacecraft, as against placing it in an 800 km polar orbit. Hence, similar to the version of the PSLV used for India's maiden unmaned lunar journey, the Chandrayaan-1 mission, the rocket has been equipped with larger strap-on motors and uses 12 tons of solid propellants instead of nine tons in the standard configuration.


September 2011 Indo-French Megha-Tropiques flight

Following the launch of GSat-12 will be the joint Indo-French Megha-Tropiques flight in September 2011.

The main aim of the mission is "to study tropical meteorological and climatic processes". It will help in carrying out atmospheric research focusing on the evolution of monsoons and cyclones.

The satellite, weighing a mere 500 kg, will be flown by only the core of the PSLV, without an additional six strap-on motors. Its lift-off will take place from the Satish Dhawan Space Centre.


2011 year-end launch of Risat-1

The year will end with the launch of the 1,780 kg Radar Imaging Satellite (Risat-1) in December 2011, again with the PSLV.

Equipped with the Synthetic Aperture Radar, Risat-1 will be placed in the 610 km polar sun synchronous orbit, and will help in all-weather observations and strengthen studies related to areas like agriculture and disaster management.

ISRO launched Risat-2 on April 20, 2009 ahead of Risat-1 for its military applications, following the terrorist attack of Mumbai on November 26, 2008. Supposedly a spy satellite, Risat-2 keeps track of potential infiltrators across the Indo-Pak border.


Mid-2012 launch of Gsat-14

ISRO chairman, K. Radhakrishnan, has announced that a 2,050 kg communication satellite called GSat-14 – one of the heaviest to be built in India – is slated for launch in mid 2012. The rocket will be the GSLV using the indigenous cryogenic engine.

It will be a nail biting mission because this the first time the home-made cryogenic engine will be flown after its failure on April 15, 2010.

In the next 60 days, what is known as a thrust chamber static facility would start functioning at ISRO's Liquid Propulsion Systems Centre at MahendraGiri in Tamilnadu.

The static facility will be used to test the S-200 solid propellant motor of the advanced version of the GSLV, called the GSLV Mark 3 version.

It is anticipated that once the GSLV Mark 3 becomes operational in three years, it will be used to launch heavy communication satellites weighing four tons and more. Hopefully, this will signal the end of India's dependence on French company Arianespace for satellite launches.

PSLV-C17 to Launch GSAT-12 on July 15, 2011 [/size]

 Preparations for the forthcoming launch of Polar Satellite Launch Vehicle (PSLV-C17) carrying India's communication satellite GSAT-12 are progressing well at Satish Dhawan Space Centre, Sriharikota. The launch of PSLV-C17/GSAT-12 mission is targeted for July 15, 2011.

GSAT-12 Communication satellite with a mass of 1410 kg at lift-off, has 12 Extended C-band transponders. PSLV-C17 will inject GSAT-12 into an elliptical Transfer Orbit (Sub-GTO) of 284 km perigee and 21,000 km apogee. Subsequently, the Liquid Apogee Motor of the satellite will be used to raise both apogee and perigee of the Satellite to place it in a circular orbit of 36,000 km altitude.

All the four stages of the launch vehicle have been fully assembled at the Vehicle Assembly Building at Shriharikota. Presently, the vehicle is going through various levels of electrical checkout operations and reviews.

GSAT-12 satellite has already undergone necessary testing at Shriharikota before commencing the filling of propellants in the Satellite on June 28, 2011. On July 3, 2011, GSAT-12 Satellite is planned to be integrated with PSLV-C17 vehicle at the Vehicle Assembly Building, after clearance by the Launch Authorisation Board.[/size]

A GSLV with an indigenous cryogenic stage would be launched from Sriharikota by June 2012, said P.S. Veeraraghavan, Director, Vikram Sarabhai Space Centre, Thiruvananthapuram.

Asked whether the PSLV-XL version would be used more often to put the ISRO's communication satellites in orbit than India's Geo-Synchronous Satellite Launch Vehicle (GSLV) or the Ariane vehicle of Arianespace, Dr. Radhakrishnan said the GSLVs were "more efficient and powerful" than the PSLVs. The GSLVs could put a 2.2-tonne communication satellite in a GTO but the PSLV-XL version could put only a 1.4 tonne communication satellite in a sub-GTO.

The GSAT-12, with its 12 extended C-band transponders, would boost ISRO's transponder capacity from 175 to 187. The ISRO had 211 transponders from its communication satellites at the beginning of the 11th Plan but it went down to 141 by April 2011 because of a series of failures with the GSLV flights. Dr. Radhakrishnan was confident that the ISRO's transponder capacity would go up to 215 by April 2012 with a series of launches of communication satellites from India and abroad. For instance, the GSAT-10, with 30 transponders, would be launched by an Ariane vehicle from Kourou island in French Guiana in April 2012.

An arbitration process would get under way between Antrix Corporation, the commercial arm of the Department of Space, and the Devas Multimedia Private Limited if the negotiations between the senior officials of the ISRO and Devas did not fructify, the ISRO Chairman said. (The ISRO annulled the allocation of 3G spectrum to Devas after allegations were made that the spectrum was sold to Devas at a low price). If arbitration was resorted to, the ISRO and Devas would each name an arbitrator of their own and these two would name another arbitrator. During the arbitration, which would take place in New Delhi, the Indian laws apply, he added.

"Good progress" had been achieved in realising the orbiter, lander and rover of the Chandrayaan-2 mission, slated to take place in 2014, said Mr. Alex. While India would make the orbiter and the rover, Russia would contribute the lander. The rover was undergoing tests in Bangalore on how to cross the obstacles on the lunar soil. Its engineering model would soon be ready. [/size]

On the progress of Chandrayaan-II mission , ISRO Space Commission Member and Director T K Alex said it was expected in the beginning of 2014.

"It is in progress. This time we are examining the lander, rover and the orbitor. The designing stage has been completed. The prototype of the rover is being made in Bangalore and the testing is going on," he said.

Russian Space Agency was involved in the developing of the rover. "By 2014 beginning, GSLV will launch Chandrayaan-2, estimated to cost Rs 425 crore", he said.

ndia's space agency has plans to launch a manned space mission in the future, but a lot of work needs to be done before that to ensure such missions are failure-proof, a top scientist has said.

K. Radhakrishnan, chairman of ISRO, said here that the space agency will have to first master the rocket technology to launch heavy communications satellites before it can progress to a manned mission.

"Rockets that carry humans cannot have a failure rate of more than two per thousand flights," he said after the successful launch of latest communications satellite GSAT-12 from the space port.

"Further what we have now (Geosynchronous Satellite Launch Vehicle) is only an unmanned rocket where the reliability should be 99 percent," Radhakrishnan said.

"We are trying to understand the intricacies of manned space mission. ISRO has to work on areas like thermal protection, life support and crew escape systems."

"We had a long discussion on manned space mission. The initial plan was to put two humans in space for seven days," he added.

According to him the first mission is to build a reliable GSLV rocket for launching heavy satellites.

He said ISRO is expected to be ready with a GSLV rocket to be powered by its own cryogenic engine next year.

Queried about the second space capsule recovery experiment (SRE-2), P.S. Veeraraghavan the director at the Vikram Sarabhai Space Centre, said the capsule is in the final stages of integration and the mission will be sometime next year.

Meanwhile, ISRO will follow a multi pronged approach to augment its transponder capacity - automatic receivers and transmitters for communication and broadcast of signals, a top official said.

"We can lease transponders from other satellite operators and launch our own satellites. ISRO (Indian Space Research Organisation) currently has 175 transponders whereas the demand is for 200 more transponders," Radhakrishnan said.

He said ISRO will launch a three-tonne communication satellite GSAT-10 with 30 transponders using Ariane rocket.

What happens to the special satellites GSat-6 and 6A that were promised for Devas' services in the annulled pact? What is the status of GSat-6?

 GSat-6 and 6A are for strategic and societal needs. As for GSat-6, some more work has to be done on it. It should be up sometime in fiscal 2012-13 on the second indigenous GSLV planned from now. (It will come up) about six months after the next GSLV-D5 vehicle that will carry GSat-14 satellite around the second quarter of 2012.

Two more this year

 This year ISRO will launch two more satellites.

 It is now getting ready for the launch of Megha-Tropiques satellite, an Indo-French joint venture, from the spaceport at Sriharikota by the end of September.

 The PSLV-C18 will put the 1,000-kg Megha-Tropiques (Megha in Sanskrit means cloud and Tropiques in French means tropics), being built by the ISRO Satellite Centre, Bangalore, into an 867 km orbit. It will be useful in studying the weather in tropical countries.

For surveillance

 ISRO is also building for surveillance, RISAT-1 (Radar Imaging Satellite) which will be put in orbit by the end of December by PSLV-C19.

 It can take pictures of the earth day and night and in all weather conditions.[/size]

PSLV-XL: ISRO's new power vehicle[/size]
 
Posted On: Jul 20, 2011      
 
PSLV-C17 lifts off from from Sriharikota spaceport. An ISRO photo
The Polar Satellite Launch Vehicle (PSLV) of ISRO has remained India's most reliable and unassailable "workhorse" in carrying out space missions for nearly two decades.

The recent successful launch of GSAT-12 communication satellite by the PSLV-C17 rocket has not only reestablished the space agency's reliability on the indigenously-built launch vehicle, but also added another feat to the glorious list of PSLV rocket variants – the powerful PSLV-XL configuration.

The advanced PSLV-XL model has proved its worth for the second time in three years during last week's launch.

The new powerful launch vehicle variant that placed the Chandrayaan-1 – India's first mission to Moon – into geostationary transfer orbit (GTO) in October 2008, has once again successfully inserted the 1,410 kg GSAT-12 into an orbit 284 km perigee (closest point to Earth) and 21,000 km apogee (farthest point to Earth) on July 15.

ISRO's indigenously-built Polar Satellite Launch Vehicle's list boasts of three models – PSLV standard, PSLV CA (core alone) and PSLV-XL. The PSLV-XL is an advanced version of the rocket with more power and payload carrying capability.

While the PSLV standard configuration has a lift off capability of 1,678 kg to place 622 km into the sun synchronous Low Earth Orbit (LEO) and the PSLV CA variant has the capability to place satellites up to 1,100 kg into the same orbit, the PSLV-XL, on the other hand, has a payload capability of 1800 kg that can be injected into the geostationary transfer orbit which is a highly elliptical Earth orbit.

The PSLV-XL also uses more power as compared to the original PSLV rocket. While the standard PSLV rocket configuration uses nine tonnes of solid propellant in four strap-on motors, the PSLV-XL model uses 12 tonnes of solid fuel on its six extended solid strap-on motors called PSOM-XL.

The advanced rocket, with a 320 tonnes lift-off mass, uses the larger strap-on motors to achieve higher payload capability.

The recent GSAT-12 launch is the third successful PSLV mission of placing a satellite into the GTO in which the PSLV-XL configuration has been used for the second time after the Chandrayaan-1 Moon mission launched by PSLV-C11.

ISRO, which used the standard PSLV rockets to launch India's remote sensing satellites into the polar sun-synchronous orbits at a height of 600 km to 800 km above Earth, achieved a major breakthrough in 2002 by putting a communication satellite into geostationary transfer orbit (GTO) having a height of 36,500 km above the Earth.

A modified PSLV-C4 rocket had successfully injected India's Kalpana-1 communication satellite into an orbit 250 km perigee (nearest point to Earth) and 36,000 km apogee (farthest point to Earth).

At a time when ISRO's ambitious goal to develop an indigenous Geosynchronous Satellite Launch Vehicle (GSLV) to launch heavier geostationary satellites appears to be delayed following two unsuccessful launch attempts in 2010, the new PSLV-XL offers quite a reliable option to launch such satellites into the geostationary orbit in near future.

Hence, the space agency has lined up some more PSLV-XL launches in the coming months.

The new power vehicle is scheduled to launch some key satellites, including the imaging satellite RISAT-1, nano satellite Jugnu and India's first dedicated astronomy satellite, Astrosat, into space.

The success of these forthcoming missions will provide an alternative solution to launch geostationary satellites till India succeeds in its own GSLV programme.[/size]

ISRO Built Super Computer

ISRO has built a supercomputer, which is to be India's fastest supercomputer in terms of theoretical peak performance of 220 TeraFLOPS (220 Trillion Floating Point Operations per second). The supercomputing facility named as Satish Dhawan Supercomputing Facility is located at Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram. The new Graphic Processing Unit (GPU) based supercomputer named "SAGA-220" (Supercomputer for Aerospace with GPU Architecture-220 TeraFLOPS) is being used by space scientists for solving complex aerospace problems.

Forthcoming Missions

Preparations are on for launching Megha-Tropiques satellite on board PSLC-C18 during end September. Megha-Tropiques (or MT -Megha means "cloud" in Sanskrit; Tropiques is the French word for "tropics.") is a cooperative experimental mission of ISRO and CNES, the space agencies of India and France, with the objective to study the convective systems (water cycle and energetic exchanges) that affect the ITCZ (Inter-Tropical Convergence Zone), in particular in the latitudes between 10

ISRO's eyes in the sky to watch climate change[/size]
TNN | Aug 24, 2011, 03.34PM IST

NAGPUR: Climate change is on everybody's minds these days. The National Remote Sensing Centre (NRSC) of Indian Space Research Organisation (ISRO) has also planned to launch some sophisticated satellites to keep a watch on climate change.

Director of NRSC V K Dhadwal, who came calling to the Regional Remote Sensing Centre in the city, spoke about the importance of keeping a watch on the changes in climate and the role remote sensing can play in it. The most ambitious projects include Megha-Tropiques, INSAT-3D, Saral Altika and SCATSAT among others. He said not just ISRO but other national and international space bodies including NASA and United Nations' Environment Programme (UNEP) had been taking serious actions in this regard too.

As the name suggests, Megha-Tropiques would help analyse the rainfall pattern while the advanced INSAT-3D would be exclusively used for meteorological purposes. Dhadwal was especially excited about Saral, which was being developed with help from French scientists, as it would be the first spaceborne altimeter to operate at K{-a} band. SCATSAT, that he said would be in use only in 2014, would be entirely dedicated to climate monitoring.

"So many factors on which the minor and major shifts in climate pattern depend, like land under cultivation and forests, snow cover, and river discharge can be observed with the help of satellites. These factors can not only help in assessment of the various climate changes but also help in analyzing and reanalyzing the changes as there would be so much data collected over a long period of time," he explained.

That the last decade was the warmest we have observed was an undeniable fact. This has come to be known as global warming. "This phenomenon, too, is only a part of climate change. The Earth has had sea levels and oxygen levels higher than what we see these days. The difference is that previous ones occurred due to natural reasons and at lesser frequency," Dhadwal said. The changes being seen now are result of human activities and occurring more frequently, he added.

It was important to keep an eye on the changes in order to understand the reasons behind them, assessing their impact on the various human activities and helping ourselves adapt to the changes, he added.[/size]

New Delhi,  September 11, 2011
India to have one more satellite launch site[/size]
PTI

 Amid requests from various countries for launch of their satellites, India has decided to set up one more launch site to expand its capacity in this aspect.

At a meeting held by the Prime Minister's Principal Secretary T.K.A. Nair here to review performance of the Department of Space, it was decided that a feasibility study would be conducted for a new site, sources said.

The decision to find a new site was taken after the meeting was told that ISRO has only two satellite launch pads, both of which are affected during the cyclone season, the sources said.

The two launch pads are located at Sriharikota High Altitude Range (SHAR).

During recent years, there have been requests from a number of countries for launching their satellites in India.

The meeting was also informed that despite successful launch of GSAT-8 and GSAT-12 satellites, there is shortage of transponders primarily due to DTH and communication requirements.

It was decided that steps should be taken to meet the gap within two years, the sources said.

At present, Department of Space is leasing transponders and using foreign launch vehicles to meet the needs.

The sources said thrust is being given by the PMO on these spheres as part of Prime Minister Manmohan Singh's desire to see boost in scientific innovation in the current decade.

Pursuant to Prime Minister's keenness, government has decided to push contribution of private sector in scientific research and development from the current 20 per cent to 50 per cent and undertake a number of other crucial steps.

The meeting felt that investments in research and development in the country is "highly skewed" as 80 per cent of contribution comes only from the public sector.

It was noted that in advanced and emerging economies, private sector plays a dominant role in R&D and encourages innovation, the sources said.

Accordingly, it was decided that secretaries concerned would jointly prepare a proposal on private sector investment in R&D by the end of next month, they said[/size].

ISRO to focus on new communication satellites, GSLV[/size]     
02 September 2011    

Bangalore: The Indian Space Research Organisation (ISRO) will build a new class of communication satellites with increased capacity and new technologies, according to chairman K Radhakrishnan.

These satellites will handle larger amount of power and carry a larger number of transponders on the same satellite, he said. Radhakrishnan also said that ISRO planned to incorporate new technologies in these satellites and step into higher bands.

"Today, we are at Ku band. We want to get into Ka band and even higher band. This is one of the priorities (in the coming five-year plan (which starts in April next year)", Radhakrishnan said.

He is also chairman of the Space Commission and secretary in the department of space.

"In remote sensing (satellite field), we have to get into environmental studies and climate change studies. This is one requirement, new requirement (in the next five-year plan)," he said.

He also revealed that ISRO would launch its first navigation satellite next year, which will be part of the Indian Regional Navigation Satellite System (IRNSS) programme. The first of the series will be followed by six more such satellites.

"So, these will have live coverage over Indian region," Radhakrishnan said.[/size]

S200 Booster Tested at SDSC[/size]
Here's video of ISRO's recent test of the S200 solid rocket booster, at Satish Dhawan Space Centre. Meant for use in the upcoming GSLV-MkIII, the S200 is the world's 3rd largest booster of its kind, after the ones used by Ariane-5 and the Space Shuttle (well, since the Space Shuttle is now retired, I guess that would make this the 2nd-largest such booster). China and Russia use purely liquid-fuel technology. Solid rocket boosters offer superior thrust performance in comparison to liquid boosters, but cannot be throttled during flight.[/size]
