    Three satellites in good health

    CHENNAI: The three satellites put in orbit on Wednesday by the Polar Satellite Launch Vehicle (PSLV-C16) are “absolutely fine,” officials of the Indian Space Research Organisation (ISRO) said on Thursday.

    The Resourcesat-2, the Youthsat and the X-Sat were in good health and working satisfactorily, they said.

    The Resourcesat-2, an advanced remote-sensing satellite, will replace the Resourcesat-1, which was put in orbit in October 2003. The Resourcesat-2 has been fitted with three sophisticated cameras, and the first images of the earth are expected on April 28. Though the Resourcesat-1's life was five years, it was still sending pictures of the earth.

    The images from the Resourcesat-2 will be useful in estimating the acreage of crops and the stress they are under, keeping a surveillance on pests, locating groundwater, identifying schools of fish in the sea, predicting the advance of glaciers, monitoring water bodies and keeping a watch on deforestation or changes in the rural and urban landscape.

    They can also be used for estimating the salinity or acidic conditions of the soil owing to the excessive use of fertilizer, and for disaster management, mapping wetlands and categorising wasteland.

    The Resourcesat-2 also carries a payload from Canada, which receives signals from ships and provides information about their location and speed. The estimated life of the satellite is five years, and its images will be used by more than 15 countries.

    The Youthsat has three payloads — one from Moscow University and two from ISRO. Together, they will help in investigating the relationship between activities in the sun and the thermosphere-ionosphere above the earth. The X-Sat of the Nangyang Technological University of Singapore is an earth-viewing satellite.

    The Resourcesat-2 is India's 18th remote-sensing satellite. A series of Indian Remote-sensing Satellites (IRS) have been put in orbit, beginning with IRS-1A in March 1988.

    “The imaging systems in the IRS series have demonstrated India's technological leadership at the global level in observing the entire earth,” an ISRO official said.

    The nine IRS in service now are the Technology Experiment Satellite, the Resourcesat-2, the Cartosat-1, 2, 2A and 2B, the Indian Mini Satellite-1, the Radar Imaging Satellite-2 and the Oceansat-2.

    They make the IRS system the largest civilian remote-sensing satellite constellation in the world.

    India eyeing collaboration with JPL in 2016 NASA Lunar Mission

    Sriharikota (AP), Apr 20 (PTI) India could be part of the 2016 NASA Lunar Mission with its space agency ISRO mulling a collaboration with the US-based Jet Propulsion Laboratory on study of farther side of the moon.
    "We are in the planning phase, for a joint mission with Jet Propulsion Laboratory (JPL) of the NASA. The mission involves getting samples from the moon and JPL wanted ISRO to get the communication module," ISRO Chairman K Radhakrishnan told reporters here.
    Speaking after the successful launch of Resourcesat-2 from the spaceport here, he said, "ISRO is one of the three candidates NASA could be considering for the 2016 mission."
    JPL, which has 20 spacecraft and nine instruments conducting active missions being important parts of NASA''s programme of exploration of the solar system and the universe beyond, wanted samples from the farther side of moon which has larger craters.
    On forthcoming launches, he said ISRO was planning a series of communication and remote sensing satellites starting from next month while activities regarding Chandrayaan-II, the country''s next Lunar mission, were progressing.
    Chandrayaan-II was tentatively scheduled for a 2013-14 launch and its Rover and Orbiter would be from ISRO while the Lander would come from Russia.
    The mission, which would also have a few scientific instruments, would be launched from a GSLV platform, he said.
    India would launch its communication satellite GSAT8 next month from French Guyana. It would be followed up with another communication satellite on a PSLV later.
    "We are also planning to launch a remote sensing satellite on the more challenging and major area of microwave remote sensing," he said.
    P S Veeraraghavan, Director, Vikram Sarabhai Space Centre, said India was also planning a joint venture with France for megha-tropiques satellite for atmospheric studies.
    On the failure of India''s much-touted indigenous cryogenic stage in GSLV F-06 in December last, he said the problem occurred after an inadvertent separation of shroud.
    ISRO was now re-working on designs specifications and planning for a test flight by the end first half of 2012.
    Some test connected with booster turbo pumps in this regard were successfully conducted yesterday, S Ramakrishnan, Director, ISRO''s Liquid Propulsion Systems centre, said.
    Responding to a query on India''s manned Moon mission, Narayanamoorty, a senior scientist associated with the project, said works were on space suit design and crew module development and a proposal had been sent to the government.
    On today''s launch, he said Resourcsat-2 will be India''s "mainstay" in remote sensing as well as commercial applications.

    ISRO to build orbiter for NASA

    The National Aeronautics and Space Administration (NASA) has asked the Indian Space Research Organisation (ISRO) to build an orbiter that will provide the communication between the soil samples collected from the far side of the moon and the earth, according to ISRO Chairman K. Radhakrishnan.

    This joint venture between the ISRO and the Jet Propulsion Laboratory in Pasadena, California, would be part of the Moonrise missions planned by the NASA.

    “This project is in the planning phase, alongside India's lunar mission programme centred on Chandrayaan-2,” he said.

    The ISRO would provide an orbiting communicator to the NASA for this mission, scheduled for 2016.

    Chandrayaan-2 would be put in an orbit around the moon by a Geo-synchronous Satellite Launch Vehicle (GSLV) in 2013 and the project would cost Rs.462 crore, Mr. Radhakrishnan said. It would be a joint mission with Russia: while the spacecraft and the rover would be built by India, the lander would be from Russia.

    The two-member committee the Centre had appointed to go into the allocation of the S-band spectrum to private company Devas by ISRO's commercial arm Antrix Corporation had submitted its report. The government would give it to the ISRO, which would act on it, he said.

    Weak Russian component downed GSLV: Ex-ISRO chief

    The destruction of India’s Geosynchronous Satellite Launch Vehicle (GSLV) in mid air in 2010 was due to an inherent weakness in a component in the Russian supplied cryogenic engine.”We did several simulation tests to find out why the connectors – the wires that carry command signals from the onboard computers at the top to the rocket’s engines down below – snapped,” former ISRO chief Madhavan Nair told IANS.



    Nair, who headed the Failure Analysis Committee, said the 12-member panel submitted its report to ISRO two weeks back.



    According to ISRO, the failed component, called shroud, was made of composites and is part of the Russian cryogenic engine. It got deformed due to the flight load.



    ISRO’s 418-tonne GSLV rocket (cost Rs.175 crore) carrying advanced communication satellite GSAT-5P (weight 2,310 kg, cost Rs.150 crore) veered off its flight path and began disintegrating within a minute after lift-off from Sriharikota in Andhra Pradesh last Christmas day. As the weakness was inherent in the shroud, Nair said ISRO should have a dialogue with the Russians to see how the component could be strengthened.



    Informed sources told IANS that even in the GSLV-F04 rocket launched in 2007, one of the connectors got snapped due to weak shroud. “The fault was there from the first GSLV that flew with the Russian cryogenic engine in 2001. The weakness in the shroud caught ISRO on December 25 last year,” a source told IANS.



    Experts told IANS that the first 15 km of a rocket’s flight was very crucial as it is subjected to heavy atmospheric loads. It is more so when the rocket is escaping the earth’s gravitational pull at 330 metres per second.



    The flow of air along the rocket will be turbulent at the transonic speed – when the rocket crosses the speed of sound. At that point the air will attach to the rocket at some places and detach at some spots in a haphazard manner.



    Out of the seven cryogenic engines supplied by Russia, India has used six. One remains to be used.



    According to Nair, it is Russia’s responsibility to set right the shroud in the remaining cryogenic engine as it is their engine and technology. “The matter has been discussed with them. But the question of compensation from Russia for the loss does not arise,” he said.



    The Russians had earlier pointed their fingers at the rocket’s bigger heat shield (4 metre) as the proximate cause for high atmospheric load on the rocket that broke it. The 2010 GSLV’s heat shield measured 4 metres in diameter as against 3.4 metre in most earlier GSLV rockets.



    A retired ISRO scientist with over two decades of experience with rocket motors told IANS that the GSLV most likely broke due to instability caused by the heavy payload – heavier than what the rocket had lifted in earlier missions.



    At 2,310 kg, the GSAT-5P communication satellite was the heaviest payload ever lifted by a GSLV.



    It was 180 kg heavier than the INSAT-4CR launched in 2007, 360-kg heavier than Edusat launched in 2003 and about 780 kg heavier than GSAT-1 launched in 2001.



    All GSLV’s that flew with Russian cryogenic engine have encountered problems carrying a payload of over 2,000 kg.



    In 2006, a GSLV rocket carrying INSAT-4C satellite weighing around 2,168 kg was blown mid air after the rocket became unstable.



    In 2007, one of the connecters of the GSLV rocket got snapped and the rocket’s performance was considered as below par. The rocket had carried 2,130 kg INSAT-4CR satellite.



    Refuting that GSLV is facing a 2,000 kg jinx, RV Perumal, a retired ISRO rocket scientist, told IANS: “The increase in the weight of the satellite is only a fraction of the rocket’s total weight (418 tonne). It is well within the scatter mass of the rocket. Hence the satellite weight is not the reason for the rocket’s instability.”



    ISRO officials also discounted the possibility of the rocket becoming unstable because of the two-tonne increase in its overall weight as compared to the April 2010 GSLV rocket that weighed 416 tonnes. “By the time the problem started, the rocket would have burned around 100 tonnes of first stage fuel. So a mere addition of two tonnes to the rocket’s weight would not make it unstable,” an official said.

    ISRO to conduct GSLV test flight in 2012 with Russian cryogenic stage engine

    SRIHARIKOTA : The Indian Space Research Organisation (Isro ) will conduct a test flight of Geosynchronous Satellite Launch Vehicle (GSLV ) with a Russian cryogenic stage engine by the first half of 2012, said its chairman K Radhakrishnan .

    The test flight would be conducted only after making necessary improvements based on the analysis of the GSLV F06 that failed on December 25, 2010.


    "We modified the booster pump in the liquid propulsion tank and tested it on Tuesday . More tests need to be conducted before it is integrated with the engine . We are also looking at a problem posed by the shroud of the rocket . The shroud failed so the connector could not function ," said S Ramakrishnan , director , Liquid Propulsion Systems Centre of Isro . Of the seven engines procured from Russia , only two are left, said Ramakrishnan .

    Two of India's GSLV launches last year had failed — GSLV (D3) on April 15 and GSLV- F06 on December 25. Isro has had a troubled past with GSLV , on which rest India's ambitious space programmes like the manned mission to space . Only two of the seven GSLV launches have been total successes. Though Isro claims that four launches had been successful, independent observers say only two of them were total successes.

    India's GSAT-8 getting ready for lift off on May 19

    KOUROU (BNS): After conducting its second successful space mission last week, Arainespace is gearing up to launch India’s large communications satellite GSAT-8 on board its Ariane 5 rocket next month.

    The ISRO-built multi-role spacecraft is undergoing an in-depth checkout at the spaceport in French Guiana in preparation for its liftoff on May 19, Arianespace, the European space transport company, said.

    Validations being performed in the Spaceport’s S5 payload preparation facility include antenna and solar panel deployments, it said.

    The company has been contracted by ISRO to launch the dual-purpose satellite, also designated INSAT-4G.

    The spacecraft had arrived at the European spaceport earlier this month.

    The satellite is fitted with 24 Ku-band transponders for telecommunications purposes. It also carries the two-channel GAGAN (GPS Aided Geo Augmented Navigation) payload.

    The GSAT-8 will have a lift-off mass of 3,100 kg and it will be accompanied by Japan’s ST-2 telecommunications satellite which will be launched by the Ariane 5 rocket on its VA202 mission.

    Resourcesat-2, Youthsat, X-Sat functioning satisfactorily

    Bangalore, Apr 25 (PTI) The country's latest remote sensing satellite Resourcesat-2 and two micro satellites launched by home grown PSLV-C16 rocket on April 20 from Sriharikota in Andhra Pradesh "are functioning satisfactorily", ISRO said. "All three satellites were placed in the targeted orbits with high precision," the Indian Space Research Organisation said in a statement here. In its 17th consecutive successful flight, PSLV-C16 injected Resourcesat-2, Youthsat and X-sat (of Nanyang Technical University, Singapore) into polar sun synchronus orbit on Wednesday last. With the precise injection of Resourcesat-2, about 20 kg of fuel allocated for the probable dispersions in injection was saved which would help enhance the five year operational life of the satellite, it said. Immediately after injection of Resourcesat 2, its two solar panels were deployed and three Imaging Cameras oriented towards Earth, it said. Orbital trimming manoeuvre was conducted successfully on April 22 and Resourcesat-2 is now placed in the final orbital configuration in a sun-synchronous polar orbit. Operation of the Imaging cameras is scheduled to commence on April 28, the statement said. The first imaging pass on April 28 is expected to cover about 3000 km stretch of Indian land mass from Joshimut in Uttarakhand to Kannur in Kerala. The statement said the health of Youthsat is normal. Control and command operations for Resourcesat-2 and Youthsat satellites are being carried out from ISRO�s Telemetry Tracking and Command Network Centre (ISTRAC) at Bangalore, connected to a network of ground stations at Lucknow, Mauritius, Biak (Indonesia), Svalbard (North Pole) and Troll (South Pole). The Earth Station of National Remote Sensing Centre at Shadnagar (near Hyderabad) has been geared up for Resourcesat-2 data reception on April 28. Payload data from Youthsat is being processed at the Indian Space Science Data Centre at Bylalu, (near Bangalore). A report by Nanyang Technological University, Singapore stated that the health of X Sat and performance of various on-board sub-systems are normal.

    ISRO joins bid to clean space debris


    THIRUVANATHAPURAM: Space agencies are starting off in a small way to clean up man-made clutter in space. The Indian Space Research Organisation (ISRO) has joined sister agencies abroad to identify methods to pluck out at least three to five large junk objects from space every year.
    A meeting of the Inter-Agency Space Debris Coordination Committee (IADC) held in Berlin from April 11 to 14 had concluded that extraction of three or five of the larger debris every year would be necessary to keep space safe for operational satellites and rocket launches.
    The IADC is a forum of 12 national space agencies including ISRO, NASA and the European Space Agency (ESA).
    ''IADC studies have shown that unless there is active removal, the possibility of selfgeneration of debris due to collisions are bound to increase.
    ISRO studies too have confirmed this,'' said Dr V Adimoorthi, ISRO's representative to IADC and dean, Indian Institute of Space Science and Technology (IIST), Thiruvananthapuram.
    In fact, the thrust now is on 'remediation' rather than 'mitigation,' he said. ISRO, which made a presentation in Berlin, will be actively participating in the 'space debris remediation' activities of IADC.
    But the big question is 'how?' Space theorists across the globe have suggested solutions as colourful as nets to laser beams, but the IADC is more realistic.
    ''Whether to remove satellites to a different, safer, orbit after a specified number of years is one of the options being considered,'' Adimoorthi, who is a former chairman of IADC, said.
    The threat posed by orbital debris has become so real that space agencies are spending significant sums to monitor orbits and debris on a daily basis.
    For instance, ISRO's space debris unit had kept its eyes skinned for hurtling junk before okaying the launch window for the recent PSLV C16 mission.
    Anything from dead satellites, spent rocket stages to slivers from destroyed objects are classified as space debris.
    There are 19,000 'catalogued' junk that are 10 cms and larger in size whizzing through space at speeds reaching 24,000 km per hour.
    Smaller objects number in the millions. At those speeds, even a tiny object can cause considerable damage to satellites.
    Most of the objects are in the Low Earth Orbit (LEO) between altitudes of 700 km and 1,600 km.
    Two recent incidents had caused considerable heartburn to space agencies: the collision between a defunct Russian Cosmos satellite and an operational Iridium satellite; and a Chinese anti-satellite missile test in 2007. Both incidents had added to the space junk population.

    Resourcesat-2 sends first imagery

    ISRO on Thursday received the first set of high quality images covering nearly 3000 km stretch of the Indian landmass from Resourcesat-2, the country's latest remote sensing satellite. The satellite, launched successfully by PSLV-C16 on April 20 into a polar sun-synchronous orbit is "working satisfa


    ctorily," ISRO said in a statement.
    "The initial phase of operations on the satellite has been completed successfully. The first imagery covering about 3000 km stretch of Indian landmass from Joshimut in Uttarakhand to Kannur in Kerala was received and processed at the National Remote Sensing Centre (NRSC) Earth Station at Shadnagar near Hyderabad," the national space agency said.

    Resourcesat-2 has successfully replaced Resourcesat-1, which had outlived its original life.

    Two other micro satellites, Youthsat and X-sat (of Nanyang Technical University, Singapore), were launched by the home grown PSLV-C16 rocket on April 20 from Sriharikota in Andhra Pradesh, along with Resourcesat-2.

    ISRO develops India's fastest supercomputer

    [​IMG]

    The Indian Space Research Organisation (ISRO) has built India's fastest supercomputer in terms of theoretical peak performance —220 trillion floating point operations per second (FLOPS).

    K. Radhakrishnan, ISRO Chairman, inaugurated the supercomputer, SAGA-220, at the newly established supercomputing facility, named after Satish Dhawan, of the Vikram Sarabhai Space Centre here on Monday.

    Space scientists are using SAGA-220 (Supercomputer for Aerospace with GPU Architecture-220 TeraFLOPS) for solving complex aerospace problems.

    The supercomputer was fully designed and built by the space centre using commercially available hardware and open-source software components. The system uses as many as 400 NVIDIA Tesla 2070 graphic processing units (GPUs) and an equal number of Intel Quad Core Xeon central processing units (CPUs), supplied by WIPRO, with a high-speed interconnect.

    With each GPU and CPU providing a performance of 500 GigaFLOPS and 50 GigaFLOPS, respectively, the theoretical peak performance of the system amounts to 220 TeraFLOPS. The GPU-based system offers significant advantage over the conventional CPU-based system in terms of cost, power, and space requirements.

    An official release said the supercomputer cost about Rs.14 crore. The system was environmentally green and consumed only 150 kW of power. This system could be easily scaled to many PetaFLOPS (1,000 TeraFLOPS), it added.

    Devangshu Datta: Back in orbit

    The launch of Polar Satellite Launch Vehicle (PSLV-C16) from the Satish Dhawan Centre, Sriharikota went off smoothly on April 20.

    The lift-off was bang on schedule. In 18 minutes, the target altitude of 822 km was reached and three satellites were placed in orbit. The big payload was the 1206 kg Resourcesat-2, along with the 92 kg Youthsat and the 106 kg X-SAT

    That routine launch was a relief for the Indian Space Research Organisation (ISRO). The four-stage, 45-metre, 290-tonne PSLV, which went into service in 1993, is very reliable. This was the 18th consecutive successful launch. It was also successfully adapted for the 2008 Chandrayaan Mission.
    But two failed Geosynchronous SLV (GSLV) launches in 2010 had everyone on tenterhooks. ISRO has also faced much flak due to the now-cancelled deal between its marketing arm, Antrix and Devas Multimedia where transponder spectrum in an upcoming GSAT6 launch was leased for a song to Devas. Although the Rs 230 crore PSLV-C16 has no direct relevance to the Devas deal (GSAT also uses PSLV platforms), failure would have damaged ISRO’s image and hit Antrix’s revenues.

    Devangshu Datta: Back in orbit

    Control of satellites is maintained from ISRO’s Telemetry Tracking and Command Network Centre (ISTRAC) in Bangalore, which is connected to a network of ground stations at Lucknow, Mauritius, Biak (Indonesia), Svalbard (North Pole) and Troll (South Pole).

    Resourcesat 2 will replace Resourcesat 1, which is still operational, three years after its design life-span ended in 2008. Resourcesat2’s LISS-4 camera sweeps 70 km at one go. Resourcesat 2 also carries a Canadian automatic identification system (AIS) for ship surveillance — this is part of global anti-piracy plans.

    Overall, Resourcesat-2 carries three cameras of different resolutions and two solar panels for power. The images are used in mapping natural resource in applications like crop health surveys, ground water mapping, deforestation tracking, monitoring water-levels in reservoirs and lakes, snow-melt in the Himalayas and so on.

    A typical application is Forecasting Agricultural output using Space, Agrometeorology and Land-based observations (FASAL) that provides accurate crop forecasting. There are also apps in town-planning, airport and road-building design.

    YouthSat is an Indo-Russian construct, with one payload from Russia and two from ISRO. It’s focussed on upper atmosphere studies between 50 km and 1,000 km altitude. X-Sat is Singapore’s first indigenous satellite and the 26th foreign satellite launched by PSLV — an index of ISRO’s commitment to commercial launches.

    On April 28, the first high-res images came through from Resourcesat2, which is in a polar sun-synchronous orbit. Sun-synchronous orbits ensure that given parts of the Earth are surveyed at the same local time, for consistent lighting. The first images covered 3,000 kms from Joshimath (Uttarakhand) to Kannur (Kerala).

    Before April 20, there were already nine Indian remote-sensing (IRS) satellites in orbit, including Resourcesat-1. IRS images are sold commercially and Antrix generates over 20 per cent of its annual revenues (Rs 900 crore in 2009-10) from IRS.

    PSLV is a “mixed”, solid-liquid propellant, four-stage design, adapted mainly from French specs. It has at least five variants. Each stage has its own control systems. An inertial guidance system navigates, guides and offers attitude control and flight sequencing.

    PSLV are workhorses with respectable payloads of about 1600 kg. In 2011, PSLVs will launch GSAT-12, the Megha-Tropiques satellite, GSAT-6 and Radar Imaging Satellite (RISAT-1), all from Sriharikota. Another GSAT would also be launched from Kourou, French Guiana, by an Ariane rocket from Arianespace in June 2011.

    The next-generation triple-stage GSLV costs Rs 350 crore and is designed to carry a massive 4,500 kg. But the design is not yet stable. GSLV-FO6 had to be aborted and blown up within 50 seconds of launch on Christmas Day, 2010. An earlier GSLV launch in April 2010 also failed.

    Until GSLV is “pucca”, India will rely on Ariane to launch heavier satellites. The key third-stage of GSLV is a Russian cryogenic engine, developed by GlavKosmos. The first and second stage are Vikas engines, based on Ariane’s Viking. In April 2010, GSLV used an Indian cryogenic engine. All stages use Indian avionics. In December, there was a problem with a fuel booster pump; in April, ground-to-air communications failed.

    While remote-sensing has huge utility – including locating aircraft wreckage as in the recent Arunachal Pradesh tragedy – a Comptroller and Auditor General of India ( CAG) report suggests the image-processing techniques are inefficient.

    The CAG cites delays in image processing at the National Remote Sensing Centre (Hyderabad) and claims around 90 per cent of images are not utilised. An ISRO wasteland-mapping project has also been delayed for 14 years. ISRO chairman, K Radhakrishnan accepts, “The CAG findings are hundred per cent correct,” which implies an overhaul in IRS processing systems is overdue.

    For years, ISRO maintained a pristine image. It delivered a string of glittering successes. It created the satellite network, which is the cornerstone of India’s electronic media and telecom revolution. Recent events have rubbed off some of the sheen. This launch should lift morale, and put the ambitious space exploration programme back on track.

    Home: High quality imageries from Resourcesat-2 presented to PM

    High quality imageries acquired from India's advanced remote sensing satellite Resourcesat-2, launched last month, were presented to Prime Minister Manmohan Singh by Indian Space Research Organisation (ISRO) Chairman K Radhakrishnan.

    Dr Radhakrishnan called on Dr Singh along with a team of scientists from various centres and units of ISRO as well as the Department of Space.

    Resourcesat-2 was launched by Polar Satellite Launch Vehicle (PSLV-C16) from the Satish Dhawan Space Centre at Sriharikota on April 20.

    The cameras on board the satellite were operated on April 28 and the imageries have been acquired over India and many parts of the globe.

    Imageries shown to the Prime Minister covered scenes over Delhi, Bareilly, Surat and Dubai. Imageries acquired by both the LISS-4 camera and AWiFS camera were presented.

    According to an ISRO press release, Dr Singh was highly appreciative of the success of the PSLV-C16 mission, which placed Resourcesat-2 as well as Youthsat, an Indo-Russian satellite and X-Sat, a satellite from Singapore, into orbit precisely. He congratulated the entire team for the magnificent performance.

    The Prime Minister was also briefed about ISRO’s coming missions. He wished ISRO team success in all its future missions for the coming months.

    The Prime Minister was also presented with models of PSLV-C16, Resourcesat-2 and Youthsat, the release added.

    India designing reusable spacecraft

    BHUBANESWAR: Director of Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, P S Veeraraghavan on Wednesday said India`s space scientists are designing a reusable space craft, which is likely to be launched in 2030. The Indian Space Research Organisation (ISRO) is currently working on Human Spacelift Project or the man mission in 2015 and Chandrayan-II in 2013, he said.

    "The winged Reusable Launch Vehicle Technology Demonstrator (RLV-TD) has already been configured. It will give India an edge in space science as no country except the US has yet launched a reusable satellite launch vehicle," he added.

    On the man mission to space, Veeraraghavan said, "ISRO is working on it but we are yet to get the final nod from the government." He was speaking on the occasion of 13th national technology day function organized by NALCO on Wednesday.

    "Scientists are working on some critical areas of Chandrayan-II, which is ready for launch in 2013. It will consist of the spacecraft and a landing platform with the moon rover. The Rs 400 crore project is in the developing stage. In the Indo-Russian joint venture the lander will be from Russia and the rover will be a done by India. The rover will land on the moon and map a three-dimensional atlas of the moon and analyse the chemical and mineral composition of the lunar surface," he said.

    Besides, Astrosat-an astronomy satellite to study the movements of celestial bodies, has already been popular among astronomy circle. However, the senior scientist was cagey about use of remote sensing in military missions and anti-Maoist operations.
