Satellite rocket with indigenous engine to be launched in April

Thiruvananthapuram, March 23
India will join an elite club of five nations in April when a rocket carrying a satellite blasts off using an indigenous cryogenic engine, an Indian Space Research Organisation (ISRO) official said.
"So far we had been using engines from Russia," the official attached to ISRO's Vikram Sarabhai Space Centre (VSSC) here told IANS.
An indigenous cryogenic engine will power the Geosynchronous Satellite Launch Vehicle (GSLV) for the first time, he said. The US, France, Japan, Russia and China have developed their own engines.
The satellite launch vehicle to be used next week, GSLV-D3, will carry the country's advanced communication satellite GSAT-4. The vehicle's assembly is in final stages and the date of launch at Sriharikota will be known in a week, the VSSC official said on condition of anonymity.
According to ISRO, the 49-metre-tall GSLV-D3 rocket will have a lift-off weight of 414 tonnes. It will propel GSAT-4 into orbit about 36,000 km above the earth.
The VSSC official said arrangements were also on for the launch of another satellite vehicle, Polar Satellite Launch Vehicle (PSLV-C-15), in the first week of May.
It will carry an Algerian satellite, two Canadian satellites and a satellite from a college in Karnataka

ISRO to launch Geosynchronous Satellite launch vehicle-D3 next month

PTIWednesday, March 24, 2010 19:56 IST

Puducherry: ISRO would launch Geosynchronous Satellite launch vehicle-D3 (GSLV-D3), the country's first satellite launch vehicle having an indigenously built cryogenic engine, to put in orbit communication satellite GSAT4 next month, a top scientist said today

GSLV-D3 launch would be followed by launching of Polar Satellite Launch Vehicle (PSLV) C15 and Cartosat2B (a high resolution remote sensing satellite), PSLV C16 and ResourceSat2 subsequently between May and August, PS Veeraraghavan, Director of Vikram Sarabhai Space Centre, Thiruvanathapuram, said here.

He was speaking at a one-day national symposium -- application of nuclear space technologies for the benefit of farmers -- organised jointly by Hyderabad-based Consortium of Indian Farmers associations and Puducherry-based Perunthalaivar Kamarajar Krishi Vigyan Kendra.


Veeraraghavan said launching of a series of remote sensing satellites, like Resourcesat-2 (to provide valuable imaging services) and Cartosat (to enable availability of more minute details for farm sector) would lay foundation for the country's development

ISRO gearing up for series of launches between April-August
Puducherry | Wednesday, Mar 24 2010 IST

The launch of GSLV-D3, GSat-4, PSLV-C15, Cartosat-2B and PSLV-C16 will take place between April and August this year, Director, Vikram Sarabhai Space Centre P S Veeraraghavan, said today.

Inaugurating a national symposium '' Application of Nuclear and Space Technologies for the beneift of Farmers'', jointly organsied by the Consortium of Farmers Association and the Kamarajar Krishivigayan Kendra here he said space technology will provide unlimited benefits both direct and indirec, to the farm sector. It has been proved that such benefits were of great help to farmers.

'' Presently we are in a position to produce sufficent food grains .But there are still areas where Green Revolution should take place in several ways, he said. A remote sensing satellite and cartosat would soon be launched so that the benefits of space technology through such initiatives would be accessible to farmers also, he said.

Later, in an informal chat with newspersons, he clarified that GSLV-D3 with an indegenously designed cryogenic engine would be launched in April. Hitherto, Russian made engines were being used.

He said the cryogenic engine would carry GSAT-4, an advanced communication satalite. He said India's development in communications and media will enable the country to launch atleat eight satellites in a year vis-a-vis four presently. The capability would be increased gadually,he added.

Bangalore: India is developing a winged reusable rocket and the Indian Space Research Organisation (Isro) has configured a Technology Demonstrator as a first step towards realising it, the space agency said in a report.

India's space scientists have already configured a winged Reusable Launch Vehicle Technology Demonstrator (RLV-TD). This is a first step towards realising a Two Stage To Orbit (TSTO) fully re-reusable launch vehicle, according to Isro.

The agency said in its latest annual report that a series of technology demonstration missions have been conceived.

"The RLV-TD will act as a flying test bed to evaluate various technologies like hypersonic flight, autonomous landing, powered cruise flight and hypersonic flight using air breathing propulsion. First in the series of demonstration trials is the hypersonic flight experiment (HEX)," it said.

Meanwhile, for the Chandrayaan-2 mission, expected by 2012-13, ISRO has received 36 Indian payload proposals for orbiter and lander/rover.

The Scientific Advisory Board of Chandrayaan-2, a follow-on mission to Chandrayaan-1, is currently in the process of reviewing the payloads proposed for orbiter.

Isro sources said the space agency has also received foreign proposals evincing interest to send their instruments for hosting by the Chandrayaan-2 which would be jointly developed with Russia.

It would have an Indian orbiter and mini-rover, and Russian lander and rover. According to Isro, the Megha-Tropiques satellite, an Indo-French joint mission for the study of the tropical atmosphere and climate related aspects, is expected to be launched later this year.

It is set to join a string of global spacecraft designated to study climate change.

"Considering the strong global demand for data from Megha-Tropiques, Isro, CNES (French space agency) and Nasa haveagreed to integrate this satellite into Global Precipitation Measurement (GPM) constellation of satellites," Isro said.

"With this, Megha-Tropiques will be one of the eight satellites contributing to the global scientific community to study and understand the dynamics of climate system," it said.

Data from the recently-launched Oceansat-2, which carried an atmospheric sounder 'ROSA' from Italy apart from main payloads — ocean colour monitor and scatterometer — is highly sought after by international scientific community.

In this respect, a cooperative programme on sharing the data with National Aeronautics and Space Administration and National Oceanic and Atmospheric Administration for their operational research is expected to be signed shortly, it said.

ДЖАКАРТА, 29 мар - РИА Новости, Михаил Цыганов. Сингапур намерен летом этого года стать первой страной Юго-Восточной Азии, запустившей в космос самостоятельно произведенный искусственный спутник Земли, сообщает в понедельник газета Straits Times.

Собранный с нуля в "городе Льва" спутник X-Sat весом в 120 килограммов, разработанный специалистами Наньянского технологического университета и сингапурских национальных военных лабораторий DSO, должен быть выведен на орбиту в июне-июле 2010 года с индийского космодрома в штате Андхра-Прадеш.

Работа над сингапурским спутником началась еще девять лет назад, и первоначально его запуск был назначен на 2007 год. Однако в тот раз он был отложен без указания причин, отмечает издание.

ЦитироватьThe X-Sat (intended to be Singapore's first satellite, launched in around 2005)

My role in this project, began in about 1999 and ended in 2006. Originally I was a simple team member working on on-board computation, but later my involvement spiralled until I became the team leader for the OBC (on board computer), RAMDISK and PPU (parallel processing unit, described in the next section). When I left NTU in 2001 to emigrate to New Zealand, I took a one year break from the project before being called back in 2002 as a consultant. In all, from 2002-2006 I was hired 5 or 6 times by NTU School of Electronic and Electrical Engineering to travel back to Singapore and manage, contribute to, audit or discuss the satellite.

In 2006 the hardware component of the OBC was complete and working, controlling a flat satellite of components spread throughout the lab (connected with CAN bus), the RAMDISK hardware was complete but the software needed finishing, and the PPU (below) was proven in prototype form. With a change in project management, I therefore 'retired' from involvement in the project, but have been very happy to contribute time and expertise to them on an ad-hoc basis ever since.

The delay in launch from 2005 to approximately 2009 was/is due to issues involved when one of the government defence departments was 'linked in' to the project, and eventually took over control from the NTU team who built the satellite (led by Associate Professor Tan Soon Hie, who also designed Singapore's first satellite payload, The Merlion, which flew in 1999 and is still the director of the university centre which controls the satellite, but is effectively excluded from day-to-day involvement). The takeover was complete by 2006, at which point I left.

Still despite the poor ending, this work has been one of the things I am most proud of. I have played my part in the internal configuration of the satellite, the early orbit modes and failure checking mechanisms are my ideas, as are some of the operating modes. The OBC OS design using VxWorks and the software architecture were dreamed up by Deepak Mohan working with me, and the PPU is essentially all my work.

Still not launched yet, this is nevertheless an impressive piece of engineering, testament to the hard work of people such as A/P Tan Soon Hie, A/P Kandiah Arichandran, A/P Naga, A/P Chua Tai Wei, Sharon Lim, Bharath Ramesh, Deepak Mohan, Prakash, Shantanu Shukla, Vipul Gupta, Amod, Madhu, Mohit and others. Many of my publications have come from the extensive work I've put in on this project.

ЦитироватьСингапур построил собственный спутник

(04:02) 30.03.2010

По информации местных СМИ, Сингапур вскоре обзаведется работающим собственным космическим спутником, созданным местными инженерами на сингапурских заводах. Ожидается, что запуск аппарата произойдет летом 2010 года. Согласно данным газеты Straits Times, 120-килограммовый микроспутник X-Sat будет иметь размеры около 1х1,5 метра и запущен в июне или июле этого года с индийского космического центра Дхаван в 100 км к северу от крупного города Ченнаи.

Примерная стоимость спутника составляет около 40 млн сингапурских долларов или около 29 млн американских долларов.

В Сингапуре говорят, что они первые из южно-азиатских стран получают собственный спутник своего производства. В создании аппарата принимали участие две научных лаборатории, а также Министерство обороны Сингапура. Straits Times сообщает, что сам спутник сейчас уже готов и специалисты проводят последние проверки аппарата перед его отправкой в Индию.

X-Sat должен будет проработать в космосе минимум три года на орбите высотой в 800 км. Он будет делать фотографии эрозии почв в стране, а также заниматься климатическим мониторингом. Также здесь установлены телекоммуникационные мощности.

ЦитироватьBoeing eyes collaboration with ISRO

Boeing has evinced interest in collaborating with Indian Space Research Organisation in the area of communication satellites, and the two entities are exploring joint opportunities, a senior ISRO official said.

But the future possible cooperation with Boeing is unlikely in the field of joint-building of communication satellites as the Indian Space agency already has a tieup in this segment with EADS Astrium, Managing Director of Antrix Corporation, ISRO's commercial arm, K. R. Sridhara Murthi indicated.

"They (Boeing) said they are interested in having collaboration with us in the field of communication satellites. But we (ISRO) already have an alliance with Europeans (EADS Astrium)," he said.

"May be some new areas of business we (ISRO and Boeing) have to explore. We need to do a lot of homework before we could arrive at collaborative level. Still, it's very preliminary type of exchange," Mr. Murthi told PTI.

ISRO, meanwhile, is expanding its alliance with Astrium, with which it has an agreement to jointly offer communication satellites with a launch mass of two tons to three tons for the international market.

"We are trying to cooperate in other areas (in addition to communication satellites) such as earth observations. So, we have built along with them (Astrium) some multi-sensor ground systems for the USA and we are also trying to cooperate in other areas and explore what other type of cooperation we can do in the field of earth observations," he said.

Antrix, which markets ISRO—developed space products and services, currently has a order pipeline of Rs 3,000 crore (all types of business put together).

The company expects to close the current fiscal (2009—10) with a revenue of Rs 1,000 crore, more or less the same as the previous fiscal, reflecting a market environment impacted by the global slowdown.

Murthi said ISRO would launch the first Algerian remote sensing satellite, built by Astrium, on board India's PSLV as a co—passenger with Cartosat—2B on May 5. This satellite weighs around 150 kg.

ISRO already has some business relationship with Algeria, which is receiving data from Indian satellites through the station built by the former.

НЬЮ-ДЕЛИ, 31 мар - РИА Новости. Индийская организация космических исследований (ИСРО) планирует ежегодно запускать на орбиту десять спутников, сказал в интервью агентству IANS директор организации Коппилил Радхакришнан.

"Мы планируем с начала 2010-11 финансового года (начнется 1 апреля) запускать по десять спутников. У нас есть серия спутников и ракет-носителей, которые находятся на разных стадиях готовности", - сказал он.

В финансовом году 2009-10, который завершается в среду, ИСРО запустила всего три спутника: "Оушнсат-2" (вместе с шестью наноспутниками), "Ритсат-2" и микроспутник "Анусат".

Также планировалось отправить на орбиту два спутника для дистанционного зондирования Земли: "Джисат-4" и "Картосат-2Б", но работы над необходимой для запуска тяжелой ракетой GSLV-D3 не удалось завершить в срок. На этой ракете впервые будет использована ступень с криогенным топливом собственного, индийского, производства вместо применявшейся ранее российской ступени.

"Мы провели совещания по запуску коммуникационных спутников и удаленному зондированию Земли. В ближайшей перспективе мы запустим один спутник в апреле и другой в мае. Целевой срок запуска "Джисат-4" - середина апреля и мы стараемся в него уложиться", - сказал Радхакришнан.

В начале мая ИСРО планирует запустить в космос на "рабочей лошадке" индийской космической программы - ракете PSLV спутник "Картосат-4", спутник для Алжира и два микроспутника.

Также намечен запуск несколько позже в текущем году спутников дистанционного зондирования Земли "Ресурссат-2", "Рисат-2" и "Мега Тропик".

Кроме того, ИСРО намерена запустить три тяжелых спутника связи: "Джисат-5" и "Джисат-6" с космодрома на острове Шрихарикота на востоке Индии.

Спутник "Джисат-8T" планируется запустить на французской ракете "Ариан" в конце 2010 или начале 2011 года. В 2011 году будет запущен спутник "Гилас" в интересах "дочки" ИСРО, корпорации Antrix, сказал Радхакришнан.

Indian Space Research Organisation
BANGALORE: Indian space scientists and engineers are bracing up to

launch an average of 10 satellites per year to meet the rising demand for

 various space applications, including communications and remote sensing, a top space scientist said.

"We are planning to launch 10 satellites per year, beginning fiscal 2010-11. We have a series of satellites and launch vehicles at various stages of preparation," Indian Space Research Organisation (ISRO) chairman K. Radhakrishnan told IANS.

Though the state-run space agency was to launch five satellites in this fiscal (2009-10), it could launch only three -- Oceansat-2, Risat-2 (radar imaging satellite) in association with Israeli Aerospace Industries, and Anusat, a micro-satellite. Oceansat-2 also carried six nano-satellites of foreign countries as additional payloads.

The launch of two satellites -- GSAT-4 and Cartosat-2B -- got delayed due to unavoidable reasons, one of them being further flight duration tests of 800 seconds (13.3 minutes) conducted for the indigenous cryogenic engine to be used for the first time in the heavy rocket GSLV-D3 (geo-synchronous satellite launch vehicle).

Hitherto, the space agency used Russian cryogenic engines in heavy rockets for launching above two-tonne class spacecraft.

"We have concluded our review meetings to launch satellites for communications and remote sensing. In the immediate, we are launching one satellite in April and another in May. Our target date for launch of GSAT-4 is mid-April and we are working towards it," Radhakrishnan said.

The space agency is set to keep the window open April 15-19 for launching the 2.2-tonne GSAT-4 onboard GSLV-D3 from its Satish Dhawan space centre at Sriharikota in Andhra Pradesh, about 80 km north-east of Chennai.

The space centre is scheduled to move the 440-tonne rocket to the second launch pad at the spaceport April 7-8 with the technology demonstrator satellite (GSAT-4).

"Early May, we plan to launch the polar satellite launch vehicle (PSLV-C15) to carry Cartosat-2B, an Algerian satellite, and two micro satellites -- Youthsat from Canada and Studsat built by college students from Karnataka," the chairman said.

India is planning to launch an average of 10 satellites per year to meet the demand for various space applications, an Indian news agency said citing a top space official.

The current ambitions of the 47-year-old national space program could vastly expand India's international profile in space and catapult it into a space race with Russia, the United States and China.

"We are planning to launch 10 satellites per year, beginning fiscal year 2010-11 [starts April 1]," the IANS agency quoted Indian Space Research Organization (ISRO) chairman K. Radhakrishnan as saying.

"We have a series of satellites and launch vehicles at various stages of preparation," the scientist said.

For the past four decades, India has launched more than 50 satellites for various scientific and technological applications such as mobile communications, meteorological observations and disaster warning.

However, last year the ISRO could launch only three satellites - Oceansat-2, Risat-2 and Anusat - out of the planned five.

This year, the Indian space agency initially plans to launch the 2.2-tonne GSAT-4 onboard domestically-developed GSLV-D3 (geo-synchronous satellite launch vehicle) in mid-April.

"Early in May, we plan to launch the polar satellite launch vehicle (PSLV-C15) to carry Cartosat-2B, an Algerian satellite, and two micro satellites -- Youthsat from Canada and Studsat built by college students from Karnataka," K. Radhakrishnan said.

ISRO is also working on launching Earth remote-sensing satellites Resourcesat-2, Risat-1 and Mega-Tropiques and three communications satellites later this year.

"In fiscal 2011-12 we plan to launch about 10 satellites, including Saral, Insat-3D, GSAT-9, GSAT-12, GSAT-10P, IRNSS 1& 2 (Indian Regional Navigation Satellite System), Astrosat and Aditya-1," the official said.

As part of its advance preparation, ISRO is also working on launching a Resourcesat-2, Risat-1 and Mega-Tropiques in the remote sensing area during the later part of this year.

'In the communications area, we are lining up three heavy satellites — GSAT-5 and GSAT-6 from Sriharikota and GSAT-8P onboard the Ariane launch vehicle from Korou in French Guayana — by this year-end or early 2011,' Radhakrishna said.

ISRO plans to put up Hylas satellite of its commercial arm Antrix before March 2011.

Noting that demand for multiple satellites in communications and remote sensing areas would increase in the coming years to meet the diverse needs of a booming economy, the chairman said the space agency was preparing to launch 10-12 satellites a year hereafter.

'In fiscal 2011-12 too, we plan to launch about 10 satellites, including Saral, Insat-3D, GSAT-9, GSAT-12, GSAT-10P, IRNSS 1& 2 (Indian Regional Navigation Satellite System), Astrosat and Aditya-1,' Radhakrishnan pointed out.

ISRO uses the Indian National Satellite (INSAT) series for telecommunication, television broadcasting and meteorological services and Indian Remote Sensing (IRS) satellites for resources monitoring and management.

The PSLV is used for launching remote sensing satellites into polar orbits and GSLV for launching communication and meteorological satellites into geo-synchronous transfer orbit.

'For launching four-tonne class satellites into GTO, we are developing GSLV-Mark III. We have already carried the static testing of the advance rocket's solid booster, which will be the third largest of its kind in the world,' he added.

Bangalore: The Indian Space Research Organisation (Isro) will begin building a space capsule to carry two astronauts on its maiden manned mission, scheduled to take place by 2016.

Isro's satellite centre will fabricate the three-member capsule using anthropometric data, or information on physical attributes peculiar to Indians. The centre will also bridge the gap in developing key restricted technologies and help plan for future missions to the moon.

Unlike the US space shuttles that glide in from space to land on a runway on their return, India will follow the Russian and Chinese method of recovering the space capsule after it drops into the ocean.

Ensuring the safe return of the occupants of the capsule, which will be launched by a rocket, will be critical.

"Reliability should be one order high. We can't risk human life. They should be 100% safe," said S. Ramakrishnan, chief executive of the human space flight programme at Isro. "We need to build multiple redundant environments, a crew escape system at every stage to bring them back safe to earth."

As part of the preparatory effort, a team of Indian astronauts will take part in one of Russia's manned missions, Ramakrishnan said. Rakesh Sharma, India's first astronaut, flew on a Soviet space mission in 1984.

The government is yet to give its nod for the Rs10,000 crore project, which will put India in a select club of nations that includes the US, Russia and China, which have undertaken manned space missions. So far, the government has sanctioned Rs380 crore for preliminary work.

"We are awaiting the project approval. Once we get it, work will begin full swing, " said S. Satish, Isro spokesperson. The Planning Commission gave its nod to the programme in February last year.

Isro will work with other national bodies such as the Defence Research and Development Organisation (DRDO), the National Aerospace Laboratories, the Armed Forces and academic institutions such as the Indian Institute of Science and the Indian Institutes of Technology for the manned mission, more than five decades after Yuri Gagarin made the first ever such trip in 1961.

The capsule for the one-week mission in low-earth orbit will have an earth-like atmosphere with oxygen supply and a real-time health monitoring system for the safety of the astronauts. Initial work on a space suit has begun at the Defence Bioengineering and Electromedical Laboratory, or Debel, a unit of DRDO in Bangalore, said C.V. Padaki, director at Debel.

Simultaneously, Isro is validating key systems for life support, rescue and recovery apart from new mission-management and control systems for the programme. Besides the astronaut training centre in Bangalore, a new launch pad for the manned mission is being built at Sriharikota on the eastern coast.

Isro first tested its capsule recovery technology in 2007, which involved heat-resistant materials necessary for the re-entry. Isro will conduct at least two unmanned space missions in the next four years.

"Building technology takes time, but the confidence we build through this project is enormous. It will take us to the next level," said Roddam Narasimha, one of India's foremost aerospace scientists.

The Institute of Aerospace Medicine (IAM), a unit of the Indian Air Force in Bangalore, has been studying pilots and the way their bodies behave in fighter jets and test conditions that replicate the vacuum of outer space. In the next two-three years, IAM will shortlist pilots who will be trained to become astronauts, from which the final two will be selected. "While we do this, we are also upgrading our existing infrastructure to train the astronauts," said Air Marshal P. Madhusoodanan, director-general of medical services.

The rocket for the mission, known as the Human Space Flight Programme, is still to be proven. India's heaviest rocket will blast off later this year: a geosynchronous satellite launch vehicle, with an indigenous cryogenic stage—an engine powered by liquefied oxygen and hydrogen that can hurl large communication satellites into orbit.

Isro's challenges include the rocket having to be man-rated, which means having an error of one in 1,000 operations, before it can be used to send up an astronaut. Once proven, it can launch a 10-tonne space capsule in lower-earth orbit carrying three astronauts, said Ramakrishnan.
