AlSat 2 [EADS Astrium]
EADS Astrium has signed in February 2006 a contract with the Algerian National Space Technology Centre (CNTS) for the development of the ALSAT-2 system, which consists of two optical observation satellites. ALSAT-2 is the first Earth observation satellite system from the AstroSat100 family to be built using the Myriade platform.
The ALSAT-2 contract covers the design and development of two satellites. The first, ALSAT-2A, will be integrated and tested in France at EADS Astrium, whereas the second, ALSAT-2B, will be integrated in Algeria within the small satellite development center (UDPS) in Oran. The ALSAT-2 programme also includes the construction of two ground control segments and one image station allowing the satellites to be operated and controlled from Algerian territory.
ALSAT-2 is equipped with a latest-generation payload capable of supplying images with a resolution of 2.5 meters in panchromatic mode and 10 meters in each of 4 colour bands in multispectral mode. It draws on EADS Astrium's extensive experience in Earth observation, most particularly with respect to the silicon carbide telescopes which are being integrated onto a Myriade class satellite platform which was designed in cooperation with CNES, the French Space agency.
The CNTS, affiliated with the Algerian Space Agency (ASAL), will be responsible for managing the ALSAT-2 programme and operating the satellite system.
The system will enable Algeria to obtain very high quality images for use in a wide variety of applications: cartography, management of agriculture, forestry, water, mineral and oil resources, crop protection, management of natural disasters and land planning.

31 Mar 2010, 1115 hrs IST,IANS
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.

PTI, Apr 16, 2010, 05.33pm IST
BANGALORE: Undeterred by the GSLV-D3 mission failure, India is going ahead with the launch of an advanced remote-sensing satellite Cartosat-2B, now tentatively fixed for May 9 from Sriharikota spaceport.
The high-resolution spacecraft, designed for an operational life of five years, is slated to be launched from the first launchpad on May 9 around 10 am, ISRO spokesperson S Satish told said here on Friday.
Thursday's GSLV-D3 mission to flight-test the indigenous cryogenic engine and stage for the first time ended in failure after the rocket veered off course and plunged into the sea.
GSLV and PSLV missions are independent of each other. ISRO officials said there is no change in its earlier announced plans to launch PSLV in the first half of May -- now fixed for May nine.
"It (Cartosat-2B) will give pictures of 0.8 metre resolution," ISRO chairman K Radhakrishnan has said. In simple terms, the single panchromatic camera on board this cartographic satellite would be able to identify and take pictures of a moving car.
Thus, this highly-agile satellite, weighing around 690 kg, is expected to give a boost to the tasks of infrastructure and urban planning. The camera provides scene specific spot imageries for cartographic and a host of other civilian applications.

ЦитироватьCartosat 2B leaves for Sriharikota
Staff Reporter
After the failure of the GSLV-D3 launch, the Indian Space Research Organisation (ISRO) on Saturday morning flagged off the Cartosat 2B high resolution satellite's journey to Sriharikota.
The remote sensing satellite is now en route to Sriharikota from where it will be launched by PSLV-16, along with four other satellites, on May 9, T.K. Alex, Director, ISRO Satellite Centre told journalists after receiving a model of a small student satellite StudSat, which will be a co-passenger of Cartosat 2B.
The 700 kg. Cartosat 2B will carry a state-of-the-art panchromatic camera with a spatial resolution less than one metre — high enough to spot a car, for instance – and will have applications in urban and rural infrastructure development and management, Geographical Information System (GIS) and other areas where detailed mapping is required.
'PICO' satellite
StudSat, the first-ever 'PICO' (small) satellite, designed in India by a consortium of 13 students from seven colleges in Bangalore and Hyderabad, weighs less than a kilogram. The payload of the satellite consists of a CMOS camera that has a ground resolution of approximately 90 metres. The mission life of the satellite is around six months and the total development cost was around Rs. 55 lakh.
The students, who had been working on this project for the last year and a half, said that it was like "a roller coaster ride," what with all the hard work they put into it and the momentous task of co-ordinating among themselves. The team was divided into various groups, each specialising in a particular aspect of the satellite: on-board communication, data handling, attitude, determination and control system, structure and ground station operations.
'Stepping stone'
Chetan Dixit, who coordinated the team, said, "We don't consider this as ultimate success. To us this is just a stepping stone to further achievements. We will now be involved with the pre-launch work, which though not technical, is very important." Alsat, an Algerian satellite, and two Canadian nanosatellites will also be launched by PSLV-16.
Governor of Karnataka Hans Raj Bhardwaj; the former ISRO chairman, U.R. Rao; Project Director for Satellites, ISRO D.A.V Murthy; and Yelahanka MLA Vishwanath spoke on the occasion.

BANGALORE: City students achieved a milestone in Indian space history on Saturday with the handing over of India's first pico-satellite to Isro.
Nitte Meenakshi Institute of Technology (NMIT) played host to the prestigious event on Saturday and a large crowd gathered to witness it. The first of its kind in the country, the satellite was designed by a consortium of seven engineering colleges from Bangalore and Hyderabad.
NMIT principal H C Nagaraj said the satellite weighs less than 1 kg. It has a volume of 1.1 litres and is designed to operate in the Low Earth Orbit (LEO). The payload of the satellite consists of a CMOS camera capable of capturing images with a ground resolution of approximately 90 metres.
The satellite, which was developed at a cost of Rs 55 lakh, will send the image and telemetry data from the orbit to the ground station Nastrac (Nitte Amateur Satellite Tracking Centre). Its mission life is estimated to be six months.
"Work on Studsat began about one-and-a-half years ago. It was initiated by the students and Isro provided great encouragement throughout the project. Students did face a few obstacles while working on it but with support from their advisor N R Shetty and principal, they managed to overcome the hiccups," said project coordinator Jharna Majumdar.
The team of Studsat said: "We took on this project because of our interest in aerospace. In fact, it happened when we attended the 58th International Astronautical Congress (IAC) in Hyderabad in 2007. Students from different engineering colleges of Hyderabad and Bangalore who attended IAC initiated the project. The realization that the project is no longer a dream, but a reality, is so exciting. Words can't capture the way we feel."
This pico-satellite, the lightest one in India, has gone through a number of critical environmental tests. The team presented a paper titled, 'Studsat — a student pico-satellite for imaging', at the IAC 2008 in Glasgow, Scotland. They won the Hans Von Muldau Award for the best team project, awarded by the International Astronautical Federation and sponsored by Deutsche Gesellschaft fur-Luft-und Raumfahrt.
The satellite is scheduled to be launched along with Cartosat-2B in Pslv C-15 in the first week of May.

"Молодежный" спутник "ЮтСат" третий год не может добраться до орбиты (http://www.rian.ru/science/20100419/224218913.html)
ЦитироватьНЬЮ-ДЕЛИ, 19 апр - РИА Новости, Евгений Безека. Запуск российско-индийского "молодежного" спутника "ЮтСат" (YouthSat), который почти два года пылится на складе в Индии, вновь отложен, сообщил в понедельник РИА Новости представитель Индийской организации космических исследований (ИСРО) Сатиш.
"Запланированный пуск ракеты-носителя PSLV состоится, ориентировочно, в июле. Она выведет в космос спутник "КартоСат". "ЮтСат" выведен на орбиту не будет", - сказал собеседник агентства.
Решение о реализации российско-индийского спутникового проекта было принято в январе 2007 года в ходе визита Владимира Путина в Индию. Он направлен на развитие контактов между молодежью двух стран. Российскую молодежь представляют студенты МГУ, собравшие "техническую начинку" спутника. Студенты университета штата Андхра-Прадеш, в свою очередь, будут анализировать полученные спутником сведения о Солнце.
Запуск "ЮтСата" первоначально был запланирован на весну 2008 года, который был объявлен Годом России в Индии. Оборудование для космического аппарата привезли из Москвы в бангалорскую штаб-квартиру ИСРО в августе 2008 года. После проведения испытаний российскую "начинку" должны были поместить в технологический модуль и осенью запустить в космос. Затем запуск перенесли на конец года, но и тогда для спутника не нашлось места на ракете. Не попал "ЮтСат" в план запусков и в 2009 году.
По словам Сатиша, в течение 2010-11 финансового года (начался 1 апреля) будут запущены пять ракет PSLV, однако конкретных планов по запуску "ЮтСата" пока нет.

IANS, Apr 30, 2010, 09.47am IST
CHENNAI: The Indian space agency is likely to launch its rocket, Polar Satellite Launch Vehicle (PSLV-C15), carrying its cartography satellite Cartosat-2B and couple of other payloads, sometime in June.
Originally scheduled for launch May 9, the Indian Space Research Organisation (ISRO) Thursday decided to postpone the flight to a future date as it found "a marginal drop in the pressure in the second stage of the vehicle during mandatory checks".
A source in ISRO told IANS: "The faulty part is in an inaccessible area as the rocket stages have been fully assembled. The second stage has to be dismantled to spot and correct the fault."
According to the source, the rocket is almost ready except for the loading of the satellites that have arrived at the launch centre in Sriharikota, around 80 km from here.
"The leak was not found during the earlier tests before the stages were integrated," the source told IANS.
The dismantling will be done from the top which involves - removal of the electronics assembly, fourth and third stages - so as take away the second stage.
The fault will be rectified at Sriharikota launch centre or if need be taken to ISRO's centre in Trivandrum which, the official said, is a remote possibility.
The 44 metre tall PSLV is a four stage (engine) rocket powered by solid and liquid propellants alternatively.
The first and third stages are fired by solid propellant and the second and fourth stages are fired by liquid propellant.
According to ISRO officials, the solid fuel stages are cast ready while the liquid fuel - Unsymmetrical Di-Methyl Hydrazine (UDMH) as fuel and Nitrogen tetroxide (N2O4) as oxidiser - measuring around 41 tonne, will be filled hours before the blast off.
Testing of the stage sub-systems will be done with nitrogen and helium gas, explained an ISRO official.
"With the help of these gases, we will test the integrity of the stage. Compared to the solid stage the liquid stage has more intricacies. It has various sub-systems, valves, turbines, regulators and other complex systems which have to be tested on ground."
Though the pressure drop was marginal, ISRO decided to postpone the flight of its successful rocket as it does not want to risk another failure in quick succession.
It may be recalled that ISRO's heavier rocket Geosynchronous Satellite Launch Vehicle (GSLV) went down into the sea April 15 as its own cryogenic engine was not able to sustain combustion beyond one second as one of its turbo pumps was not able to function continuously.
Further, PSLV has been the revenue earner for ISRO, launching third party satellites and a failure would have a reputation issue which in turn would impact a lucrative revenue stream.
PSLV this time is slated to ferry an Algerian Alsat communication satellite weighing 117 kg for a fee. The rocket will also carry two nano satellites - one each from Canada and Switzerland - a pico satellite StudSat (under one kg) developed by college students in Bangalore and Hyderabad.
However, the main cargo of the rocket is the Cartosat-2B 690-kg satellite, which will carry a sophisticated panchromatic camera on board to take higher (0.8 metre) spatial resolution imageries with a swath of 9.6 km of specific spots for cartographic applications such as mapping, land information and geographical information system.

May 6th, 2010
The Indian space agency is expected to launch June 5 its Polar Satellite Launch Vehicle (PSLV-C15), carrying a cartography satellite and a couple of other payloads, according to the US-based space consultancy firm Futron Corp.
But a source in the Indian Space Research Organisation (ISRO) said that the launch is most likely to happen during the second week of June.
The 44-metre tall PSLV is a four-stage (engine) rocket powered by solid and liquid propellants alternatively.
Originally scheduled for launch May 9, the ISRO decided to postpone the flight to a future date as it found "a marginal drop in the pressure in the second stage of the vehicle during mandatory checks".
At the time of postponement, the rocket was almost ready except for the loading of the satellites that have arrived at the launch centre.
According to ISRO officials, once the rocket is fully assembled and satellites loaded, around 10 days were needed to test the entire systems and sub-systems.
ISRO technicians meanwhile have dismantled the second stage and are carrying out tests and analysis to spot the failed component that needs to be replaced at the Sriharikota rocket launch centre, 80 km from here.
The second stage had to be dismantled as the faulty part is in an inaccessible area after the rocket was assembled fully.
ISRO official said once the faulty part is replaced, all the tests that were carried out earlier have to be done once again.
The main cargo of the rocket is the 690-kg Cartosat-2B satellite, which will carry a sophisticated panchromatic camera on board to take higher (0.8 metre) spatial resolution imageries with a swath of 9.6 km of specific spots for applications such as mapping, land information and geographical information system.
The rocket is also slated to ferry an Algerian Alsat communication satellite and two nano satellites, one each from Canada and Switzerland, and a pico satellite (under one kg) StudSat developed by college students in Bangalore and Hyderabad.

ЦитироватьIndia to Launch Five Satellites After Fixing Rocket 'Anomaly'
June 17, 2010, 6:22 AM EDT
By Jay Shankar
June 17 (Bloomberg) -- India plans to put five remote- sensing satellites into orbit in the first half of next month after fixing a rocket "anomaly" that forced it to delay launches in May.
The Polar Satellite Launch Vehicle will carry India's Cartosat-2B, Algeria's ALSAT-2A and two small satellites from the University of Toronto, P.S. Veeraraghavan, director of Vikram Sarabhai Space Centre, said by phone today from the southern city of Thiruvananthapuram. The fifth unit will be a one-kilogram satellite built by Indian students, he said.
The agency, based in Thiruvananthapuram, has corrected the anomaly, which was in the second stage of the rocket, Veeraraghavan said. The delay had disrupted India's challenge to China, Japan, and South Korea as it competes for commercial- satellite launches.
In April, India also failed in its bid to join a group of five nations using their own rocket technology to launch large satellites into higher orbits when scientists lost control of the 50-meter (164 feet) GSLV-D3 spacecraft minutes after blastoff.
"The reasons for the failure are still being analyzed and we expect a report in a month's time," Veeraraghavan said.
India is planning a $2.5 billion unmanned mission to space by 2015 and is slated to launch a second unmanned moon craft Chandrayaan II at a cost of $87.5 million before March 2013.
The Asian nation launched its first space rocket in 1963 and its first satellite in 1975. The country's satellite program consists of 21 orbiters, of which 11 are currently in service.

KARIMNAGAR: Young Harish Rao has done Karimnagar proud. He was part of the team which made 1-kg mini satellite, Pico, which will be put in orbit on July 28.
The team with students drawn from Andhra Pradesh and Karnataka was guided by the Indian Space Research Organisation, Bengaluru in their mission.
Harish Rao, a Karimnagar lad, is currently studying Mechanical engineering third year at the KITS, Ramtek in Nagpur. He briefed about the satellite to the students of Vindhya Valley High School at a programme in Karimnagar today.
He said the satellite was handed over to ISRO through Karnataka Governor Hansiraj Bharadwaj on April 17 this year. It will be launched into 700-km orbit through PSLV-C15 on July 28.
He got to attend the International Astronomy Conference (IAC) in Hyderabad in 2007 when he was studying his B.Tech first year and was inspired by a talk on the subject.
Since then his ambition was to do something constructive in space research and was guided by small satellite project director DV Raghava Murthy of Bengaluru.
His role is to ensure that the satellite after reaching the orbit clicks pictures on the earth.
It was made at a cost of Rs 55 lakh with the support of 7 institutions in Andhra Pradesh and Bengaluru.
After completing his B.Tech, Harish Rao wants to settle in some space-related research institution and do something proud for the nation.
He and his team were awarded Hansvon Muldau by the Scotland International Astronomy Vehicle conference in 2008 for presenting paper on the project. His team is also going to take part in a astronomy conference to be held in Czech Republic in September this year.
Vindhya Valley correspondent and his mother Laxmi Prakash Rao and Principal Jayes Anand congratulated Harish for his achievement and efforts to realise his ambition.

ЦитироватьAfter two setbacks, Isro set to launch five satellites on 12 July
K. Raghu
Bangalore: After two setbacks this year, India's space agency is set to launch five satellites on 12 July, including one that can shoot pictures of small objects on land and compress the time needed for building high-resolution maps by half.
In April, the Indian Space Research Organisation (Isro) lost its fourth-generation communication satellite GSAT-4 when its heaviest rocket yet—the geosynchronous satellite launch vehicle (GSLV), powered by a home-grown cryogenic engine—plunged into sea within five minutes of launch. The rocket was to put India in an exclusive club of nations capable of hurling communication satellites and offering space launches commercially.
Isro then deferred the launch of its workhorse polar satellite launch vehicle (PSLV) scheduled in May after it found leaks in the rocket's second stage. The leaks were detected when pressurized nitrogen was pumped in the rocket as part of tests on the launch pad.
The same rocket will be fired now, following repairs and further tests, said an Isro official from Sriharikota. He did not want to be named.
"Even if the leak is minor, it takes many days to rectify and certify it fit," said U.R. Rao, a former chairman of Isro. "In space, you don't take risks."
The rocket will also launch Alsat-2A, a remote sensing satellite from Algeria and India's first African customer, two nano satellites from the University of Toronto, and Studsat, a small satellite built by engineering students in Karnataka and Andhra Pradesh.
Isro's commercial arm, Antrix Corp. Ltd, has already signed a second satellite launch from Algeria for next year.
So far, PSLV has launched 39 satellites, nearly half of them from India, in 16 missions.
Isro expects Cartosat-2B to join two other satellites that are already in orbit—the Cartosat-2 and 2A—and return more high-resolution images to earth and provide complete coverage of the subcontinent, said S. Satish, director, Isro.
Cartosat-2B has a high resolution of 0.8 metre, allowing it to photograph objects the size of a typical bicycle.
Typically, satellites that can snap high resolution images can cover a small width or swath of 10km. To cover a larger area, a satellite would have to come back to a specific spot repeatedly, which would take a long time as it would have to complete one orbit of the earth to do this. A constellation of three satellites, on the other hand, can cover the entire country.
"It is like a camera; you want sharp images you need to be closer. You can go farther to cover a larger area, but you won't get minute details," said Rao.
As for the GSLV, Satish said a panel that's studying what led to its crash is set to announce its report next week.

Chennai: India's advanced, high-resolution remote-sensing satellite Cartosat-2B would be launched July 12 at 9.23 am from the Sriharikota spaceport in Andhra Pradesh, giving a boost to the country's infrastructure and urban planning.
The Indian Space and Research Organisation's (ISRO) rocket Polar Satellite Launch Vehicle (PSLV) will carry into space the 690 kg Cartosat 2B and an Algerian satellite, Alsat (117 kg).
The rocket will blast off carrying also three nano satellites - NLS 6.1 and NLS 6.2 from Canada and Switzerland, and StudSat developed by students of engineering colleges in Bangalore and Hyderabad.
'The launch is fixed for July 12 at 9.23 a.m. The rocket will carry five satellites,' S.Sathish, director (Publications and Public Relations) said from Bangalore over phone.
The rocket's main cargo Cartosat-2B is a remote sensing satellite carrying a sophisticated panchromatic camera on board to photograph specific spots closely. The pictures are useful for cartographic applications such as mapping, land information and geographical information system.
Cartosat 2B will join the other two cartography satellites Cartosat 2 and 2A launched earlier. With three satellites ISRO's satellites can cover the country effectively.
ISRO has been carrying out multiple launches for several years and in 2008 it set a world record launching 10 satellites at one go.
Originally scheduled for launch May 9, ISRO decided to postpone the launch as it found 'a marginal drop in the pressure in the second stage of the vehicle during mandatory checks'.
Though the pressure drop was marginal, ISRO wanted to be sure as it does not want to risk a failure since PSLV is a major revenue earner, carrying satellites for others for a fee.
The 44 metre tall PSLV is a four stage (engine) rocket powered by solid and liquid propellants alternatively.
The first and third stages are fired by solid propellant and the second and fourth stages are fired by liquid propellant.
At that time the rocket was almost ready except for the loading of the satellites that had arrived at the launch centre in Sriharikota around 80 km from here.
As the faulty valve was in an inaccessible area with the rocket stages having been fully assembled, the second stage had to be dismantled to take corrective action.
Even after the replacement of the faulty valve at Sriharikota the problem continued to persist and ISRO sent the second stage (engine and other systems) to Liquid Propulsion System Centre at Thiruvanthapuram in Kerala where it was originally assembled.
'The second stage was refurbished and sent back to Sriharikota,' Satish said.

The 51-hour countdown for the 17th flight launch of Indian space agency's Polar Satellite Launch Vehicle PSLV-C 15 from Sriharikota spaceport is expected to begin on Saturday morning. Preparations were in full swing for the launch of the PSLV-C-15 on July 12. All the parameters for the launch were doing well and the 51-hour countdown was expected to start at 6 am on Saturday, Indian Space Research Organisation (ISR0) officials said.
"The rocket will put into orbit five satellites – remote sensing satellite Cartosat-2B from India, Alsat from Algeria, two nano satellites from Canada and Switzerland, and a pico (very small) satellite called Studsat built by seven engineering students in Andhra Pradesh and Karnataka", ISRO spokesmen S Satish told PTI.
The PSLV launch was to take place on May 9 last but was postponed because of a drop in the pressure in the vehicle's second stage.
This would be the first mission by ISRO after the failure of India's ambitious home-made cryogenic engine powered GSLV-D3 in April last.
He said, "In this flight, PSLV will place the 694 kg Cartosat-2B and four auxiliary payloads in a 630 km Polar Sun Synchronous Orbit (SSO)".
The four-stage vehicle had been fully assembled in its launch pad and the mating with Cartosat-2B and other satellites had been completed.
He said the satellite would help in urban planning and infrastructure development such as laying ring-roads and rerouting of highways.
"Cartosat-2B carries a panchromatic camera similar to that of its predecessors - Cartosat-2 and 2A", he said adding it was capable of imaging a swath (geographical strip of land) of 9.6 km with a resolution of 0.8 metre.

CHENNAI: The countdown for Monday's launch of India's Polar Satellite Launch Vehicle (PSLV) rocket carrying five satellites, including a cartography one for land mapping and information, began Saturday at the rocket port Sriharikota.
The 44-metre tall PSLV is a four-stage rocket powered by solid and liquid propellants alternatively.
"Everything is going smoothly and we are getting ready for the Monday launch. The 50 hours, 30 minutes countdown started at 6.52 a.m. Saturday," S. Satish, director at the Indian Space Research Organisation (ISRO), told IANS from Bangalore over phone.
The rocket will blast off into space from Sriharikota, around 80 km from here, carrying the 694 kg Cartosat 2B and an Algerian satellite, Alsat (117 kg).
It will also carry three very small satellites - NLS 6.1 and NLS 6.2 from Canada and Switzerland, and StudSat - developed by students of engineering colleges in Bangalore and Hyderabad.
"The satellites were loaded atop the rocket a couple of days ago," an ISRO official said.
The first and third stages of the rocket are fired by solid propellant and the second and fourth stages are fired by liquid propellant.
According to ISRO officials, the solid fuel stages are cast ready while the liquid fuel - Unsymmetrical Di-Methyl Hydrazine (UDMH) as fuel and Nitrogen tetroxide (N2O4) as oxidiser - will be filled hours before the blast off.
The rocket's main cargo Cartosat-2B is a remote sensing satellite carrying a sophisticated panchromatic camera on board to photograph specific spots closely. The pictures are useful for cartographic applications such as mapping, land information and geographical information system.

08:33 12/07/2010
НЬЮ-ДЕЛИ, 12 июл - РИА Новости, Евгений Безека. Индийская ракета-носитель PSLV в понедельник благополучно вывела на орбиту пять спутников из разных стран, сообщил журналистам глава Индийской организации космических исследований (ИСРО) Радхакришнан.
"Полет PSLV прошел прекрасно. Это 16-й подряд успешный запуск PSLV. Она разместила на орбите пять спутников: Cartosat, STUDSAT, изготовленный 35 студентами из семи колледжей страны, и два маленьких спутника - один из Канады, один из Швейцарии", - сказал он.
Ракета стартовала в понедельник утром с космодрома имени Сатиша Дхавана на острове Шрихарикота в Бенгальском заливе. Основная нагрузка на ракете - спутник дистанционного зондирования Земли Cartosat-2B весом 694 килограмма. Он стал десятым действующим индийским спутником этого типа на орбите и позволит Индии закрепить лидирующие позиции на мировом рынке изображений из космоса.
Переданная Cartosat-2B из космоса информация дополнит аналогичные данные двух других находящихся на орбите спутников серии Cartosat-2 и найдет применение в картографии, геологии, управлении городским хозяйством и землями сельхозназначения. Спутник оборудован панхроматической камерой разрешением 80 сантиметров.
Также 44-метровая ракета вывела на орбиту 116-килограммовый алжирский спутник ALSAT-2A и три наноспутника. Два из них изготовлены в Канаде (NLS-6.1) и Швейцарии (NLS-6.2). Третий - STUDSAT весом всего 650 граммов - изготовили студенты семи институтов индийских городов Бангалор и Хайдерабад.
Индийская группировка спутников дистанционного зондирования Земли является крупнейшей в мире. До сегодняшнего запуска на ней находились девять действующих космических аппаратов: IRS-P4 (OCEANSAT-1), TES, RESOURCESAT-1, CARTOSAT-1, CARTOSAT-2, CARTOSAT-2A, IMS-1, RISAT-2 и OCEANSAT-2.
Запуск ракеты PSLV должен был состояться в мае, однако его отложили из-за выявленных перед стартом неполадок во второй ступени. Для их устранения специалистам ИСРО пришлось демонтировать всю ступень и отправить ее на обслуживание.
Незадолго до этого, в апреле, в море упала тяжелая индийская ракета GSLV, которая впервые стартовала с разгонным блоком собственного, индийского производства. До этого Индия использовала для ракет этого типа российские разгонные блоки с криогенным топливом. На прошлой неделе ИСРО опубликовала заключение комиссии, которая назвала причиной падения отказ топливного турбонаноса разгонного блока.
Из-за аварии Индии придется на время вернуться к практике использования российских разгонных блоков на GSLV. Сейчас на складах в Индии находятся два таких блока, закупленных ранее в РФ.

AGENCIES, Jul 12, 2010, 09.25am IST
SRIHARIKOTA: The Polar Satellite Launch Vehicle PSLV-C-15 carrying remote sensing Cartosat-2B along with four satellites blasted off from the spaceport near here on Monday morning.
The four-stage 44.4 metre tall PSLV-C-15 lifted off at the end of a 51-hour countdown from the Satish Dhawan space centre at 9.22 AM.
The rocket soared into skies in clear weather leaving behind plumes of smoke.
It will place four satellites into orbit, including Alsat from Algeria, two nano satellites from Canada and Switzerland, and a pico (very small) satellite Studsat built by seven engineering students of Andhra Pradesh and Karnataka.
The countdown started on Saturday morning for the launch of the 44-metre tall, 230-tonne PSLV.
ISRO has been carrying out multiple launches for several years. In 2008, it set a world record by launching 10 satellites at one go.
Built to last for five years, the Rs.200-crore Cartosat-2B is India's 17th remote sensing satellite and is meant to augment ISRO's remote sensing data services along with two other satellites, Cartosat-2 and 2A launched earlier.
The satellites' imagery can be used for preparing detailed forest type maps, tree volume estimation, village/cadastral level crop inventory, town/village settlement mapping and planning for development, rural connectivity, canal alignment, coastal land form, mining monitoring and others.
"With the launch of Cartosat-2B, ISRO will have 10 remote sensing satellites in orbit - IRS 1D, Resourcesat 1, TES, Cartosat 1, 2 and 2A, IMS 1, RISAT-2, Oceansat 1 and 2," Satish, the director for publications and public relations, said.
India is a world leader in the remote sensing data market, earning a sizeable amount.
"The other remote sensing satellites that are slated for launch are RISAT (end of 2010 or early 2011), Resourcesat and Megha-Tropiques," Satish added.

India's Polar Satellite Launch Vehicle (PSLV-C15) successfully launches CARTOSAT - 2B Satellite
India's Polar Satellite Launch Vehicle (PSLV-C15), today (on July 12, 2010) successfully launched CARTOSAT - 2B from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch of PSLV - C15 was the sixteenth consecutive successful flight of PSLV.
After a smooth countdown of 51 hrs the vehicle lifted-off from the First Launch Pad at the opening of the launch window at 09.22 hrs (IST). After about 20 minutes of flight time, India`s advanced remote sensing satellite CARTOSAT - 2B along with four auxiliary satellites was successfully injected into its circular orbit of 637 km with an orbital inclination of 98.1o.
The preliminary flight data indicates that all major flight events involving stage ignition and burnouts, performance of solid and liquid stages, indigenously developed advanced mission computers and telemetry systems were exactly as predicted.
PSLV - C15 in its flight, in addition to CARTOSAT - 2B, carried four auxiliary satellites namely STUDSAT a pico-satellite weighing less than 1 kg, built jointly by students from a consortium of seven engineering colleges form Karnataka and Andhra Pradesh, two nano satellites NLS 6.1 and NLS 6.2 from University of Toronto, Canada and ALSAT-2A, a micro-satellite from Algerian Space Agency.

Как же они могли там быть, если раньше это место было полностью занято 6-ю СТУ?
Вы, видимо, не поняли - вопрос касался только дополнительных емкостей, которых раньше не было. На приведенном фото они расположены по бокам.
Про емкости СУВТ я в курсе, но если ракете с 6 СТУ хватало двух баллонов, то ракете без них нужно ещё меньше.

Этот небольшой суперсовременный спутник будет отслеживать маршруты всех судов водоизмещением более 300 тонн, регистрируя сигналы, поступающих с их передатчиков системы автоматического распознавания AIS. Эта система используется в основном для предотвращения столкновений, а также береговыми службами для отслеживания движения грузовых, рыболовецких и пассажирских судов.
Спутник позволит Норвегии видеть в реальном масштабе времени всю картину того, что происходит на огромном водном пространстве.
"Норвегия обладает крупнейшей морской акваторией среди европейских стран, которая является источником больших доходов, от добычи нефти до рыболовства", - говорит генеральный директор Норвежского космического центра Бо Андерсен.
"Мы желаем эффективно управлять этими ресурсами, и в настоящее время мы делаем это с помощью радарных спутников, которые дают нам неплохую картину расположения судов. Но они не в состоянии идентифицировать эти суда", - добавил Б.Андерсен.
"Конечно, береговая охрана может направлять к таким судам самолеты, но речь идет об акватории, превышающей Средиземное море, и поэтому нам нужна более эффективная система", - резюмировал гендиректор Норвежского космического центра.
AISSat-1 - миниатюрный спутник, который представляет собой куб со стороной 20 см - был среди пяти аппаратов, выведенных на орбиту индийской ракетой, стартовавшей с космодрома Шрихарикота в штате Андра-Прадеш. Он весит всего 7 кг и обращается по полярной орбите высотой 600 км. Спутник уже вышел на связь и его системы работают нормально. Данные с транспондеров системы AIS передаются в диапазоне УКВ и указывают название и тип судна, его координаты, курс и скорость.
Отметим, Норвегия уже продемонстрировала способность принимать эти данные из космоса. Недавно на борт Международной космической станции был доставлено приемное устройство NORAIS, которое отслеживает движение судов по всему миру. На основе этой технологии Норвегия надеется разработать глобальную систему, которую она будет предлагать другим странам.
Спутник, создание которого обошлось в 4,4 млн евро, финансируется Норвежским космическим агентством. В его создании приняли участие также канадские компании.

Chennai: Remote-sensing satellite Cartosat-2B has sent high quality images of the Indian landmass, including Allahabad in Uttar Pradesh and Madurai in Tamil Nadu.
The images were taken by the satellite's panchromatic camera, which has a high resolution of 0.8 metre. That is, it can image even small objects such as cycles and mopeds on the road, and sheep and cattle grazing on meadows.
The Polar Satellite Launch Vehicle (PSLV-C15) of the Indian Space Research Organisation (ISRO) put Cartosat-2B and four other satellites in orbit on July 12. It was launched from Sriharikota.
P.S. Veeraraghavan, Director, Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram, said Cartosat-2B was in good health and that "it has taken a good number of pictures."
He said the images of Madurai included the famous Meenakshi temple with its gopurams (towers), the railway junction and a running train, the airport with parked aircraft, and another temple situated in the centre of a tank.
The images of Allahabad showed a fort in the town and the Triveni Sangam.
