    Very happy with HC order, says Nambi Narayanan

    (Monday 20 October 2014 09:57 PM IST)

    Kochi - In a blow to the state government, the Kerala High Court on Monday quashed the order dropping action against former Additional DGP Siby Mathews and two others who investigated the ISRO espionage case initially saying the conduct of the government 'has not been above board'.

    The high court directed the state government to reconsider the decision exonerating the officials to set everything right.

    Allowing the petition filed by Nambi Narayanan, former ISRO scientist and an accused in the case, Justice A.V. Ramakrishna Pillai remitted the matter back to the government for reconsideration and issuing formal orders within 3 months.

    Speaking to Manorama News, Nambi Narayanan said that he is very happy with the HC quashing the government order.

    "The ones behind this case were influential enough to keep this one pending when the both UDF and LDF ruled the state," he said.

    The court made it clear that 'the course of action to be taken was left open to the government but it shall not be namesake making administrative justice a mockery'.

    The judge in his 57-page order said the state government, which was 'enthusiastic' in withdrawing the case from CBI and handing it over to state police, had not taken note of the lapses in investigation by Kerala Police 'seriously', as could be seen from the records.

    "The kind of seriousness as expected from a welfare state was not shown by the state. The conduct of the state was not above board. It does not confirm with the known pattern of a responsible government bound by rule of law',the court held.

    To set everything right, the government should reconsider the decision to exonerate the three officers in the SIT, it said.

    Rejecting the argument that Kerala police are investigating over one lakh IPC cases a year, the court said this is not a 'valid reason' for a person like Siby Mathews, who led the SIT team, to justify the irregularities pointed out in the investigation.

    "The duty of an investigating agency is not merely to bolster up a prosecution case but to bring out the real untarnished truth'. The judge said while the SIT failed in that, CBI has done that.

    Nambi Narayanan had approached the court in December 2012 seeking initiation of criminal and disciplinary action against Siby Mathews and two retired Superintendents of police - Joshua and S. Vijayan who were held responsible by CBI for his illegal arrest.

    The senior scientist was accused of being involved in the espionage case but was later discharged.

    CBI had recommended action against the three SIT officials 15 years ago but action had not yet been taken against them.

    The Judge pointed out that the SIT investigated the case for less than 20 days. But it appears from the note, said to have been sent by CBI, that within that short time, 'enough damage had been done'.

    The court said it was of the 'definite view' that the commission and omission made should not have occurred during the course of fair investigation.

    As a scientist of ISRO, Narayanan, along with other scientists, has made contribution in developing the Mangalyan satellite launch vehicle.

    'While the spacecraft in the orbit rounds the Mars, the petitioner, Narayanan, continues his fight for justice', the court observed.

    In 2011, government decided to exonerate the members of the SIT and recommended dropping of all action against them. This was recorded by the high court in an earlier PIL.

    Subsequently, government's action was challenged by Nambi Narayanan. The matter was heard six months ago and the judgement was delivered on Monday.

    The espionage charges surfaced with the arrest of a Maldivian national Mariam Rasheeda at Thiruvananthapuram in October 1994. Another ISRO scientist, two Bangalore-based businessmen and another Maldivian woman were the accused in the case.

    The Ernakulam Chief Judicial Magistrate court had in 1996 exonerated all accused on the basis of a CBI report which had concluded there was no evidence to prove the espionage charge against the accused and hence they should be exonerated.

    However, in June 1996, the state government ordered a reinvestigation into the case. Though the High Court had upheld the government order, the Supreme Court quashed it in 1998.

    The apex court had criticised the government for ordering yet another investigation by the state police after the CBI probe found that the allegations were false and the magistrate court ordered the release of all the accused.

    (Very happy with HC order, says Nambi Narayanan)

    All set to put unmanned crew module into orbit


    VSSC/ISRO ISRO’s unmanned crew module undergoing tests at the Vikram Sarabhai Space Centre, Thiruvananthapuram. The maiden flight of GSLVMark III in December 2014 will put the unmanned crew module in the orbit.

    space programme


    There is frenetic activity at Sriharikota for the maiden lift-off of India’s newest and the biggest launch vehicle in December, which will put an unmanned crew module into orbit.

    The mission is a stepping stone to the Indian Space Research Organisation (ISRO) ultimately sending astronauts into space in the module.

    The 3.65-tonne module will get de-mated from the topmost cryogenic stage at an altitude of 125 km and return to the earth. At an altitude of 15 km, there will be an “aerial ballet,” featuring three huge parachutes which will open up one after the other to slow down the module’s descent. The module is expected to splash down in the sea near the Andaman archipelago and will be recovered by the Indian Coast Guard and ISRO personnel. The entire flight from the lift-off to the splash-down will last about 20 minutes. It is a passive, experimental and sub-orbital mission.

    ISRO Chairman K. Radhakrishnan said, “Everything is progressing well” for the GSLV-MkIII launch in December. The rocket weighs 630 tonnes and is 42.4 metres tall.

    “We are ready. Everything is pucca,” said M.C. Dathan, Director, Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, which has built both the GSLV-MKIII and the unmanned crew module. Two gigantic strap-on motors, each of which will use 200 tonnes of solid propellants, have been strapped around the core stage in the second launch pad. The core stage will use 110 tonnes of liquid propellants. Above the core stage is the cryogenic stage. The module will be “encapsulated” with the cryogenic stage on November 26, said Mr. Dathan.

    S. Somanath, Project Director, GSLV-MKIII, called it India’s “biggest, heaviest and the next generation” launch vehicle.

    India's Communication Satellite GSAT-16 Launched Successfully

    Augmenting India's space capacity to boost communication services, its latest satellite GSAT-16 was successfully launched on board Arianespace rocket from the space port of Kourou in French Guiana in the early hours today, after a delay of two days due to bad weather.

    The satellite with a lift-off mass of 3,181 kg was injected into the intended Geosynchronous Transfer Orbit (GTO) about 32 minutes after a perfect lift-off of Ariane 5 at 2.10 AM on flight VA221, signifying the 221st launch of an Ariane family vehicle from the spaceport.

    In the dual rocket mission, GSAT-16 with 48 transponders, the largest-ever carried by a communication satellite built by Indian Space Research Organisation (ISRO), was ejected into space four minutes after its co-passenger DIRECTTV-14 spacecraft, designed to provide direct-to-home television broadcasts across the US, Arianespace said.

    Soon after the launch, the Bengaluru-headquartered ISRO's Master Control Facility at Hassan in Karnataka took over the command and control of the GSAT-16 and said initial checks indicated "normal health" of the satellite.

    ISRO said the first orbit raising operation is scheduled for tomorrow at around 03:50 AM as part of manoeuvres to place the satellite finally in its designated slot at 55 deg East longitude in the Geostationary orbit and co-located with GSAT-8, IRNSS-1A and IRNSS-1B satellites.

    GSAT-16 Mission Update: First orbit raising operation is scheduled tomorrow (Dec 08, 2014) at around 03:50 hrs IST.

    After the successful launch,GSAT-16 is in good health. ISRO's Master Control Facility at Hassan has taken over the control of the satellite.

    — ISRO (@isro) December 6, 2014
    The launch of GSAT-16 was originally scheduled for Friday but was put off hours before the lift-off due to inclement weather at Kourou, which is chosen for its strategic location of being close to the equator that is ideally-suited for missions into the geostationary orbit.

    Arianespace rescheduled it for Saturday at 02.09 AM (IST) but within hours that too was postponed, citing "unfavourable weather conditions (high altitude winds" over the launch pad. It was then rescheduled for wee hours of today.

    "... two days we had to wait for this to happen, but it has happened excellently, so congratulations to all people from Arianespace for its excellent performance," ISRO Satellite Centre (ISAC) Director S K Shivakumar said at the Arianespace facility.

    Arianespace said today's was the 63rd successful Ariane 5 launch in a row.

    GSAT-16, a multi-application telecommunications satellite, will cover the entire Indian sub-continent. It is the 18th ISRO satellite to be launched by Arianespace, starting with the Apple experimental satellite in 1981, an Arianespace release said.

    Shortly after the orbit injection announcement, Arianespace Chairman and CEO Stéphane Israël said: "Tonight, we are very proud of meeting the expectations of these two loyal customers, whose diversity clearly reflects our clientele"

    Shivakumar said Arianespace had given ISRO the precise injection parameters as assured and in the next few days rest of the operational activities like Onboard Liquid Apogee Motor (LAM) firing and others will be carried out.

    "Subsequently telecommunication payload systems are planned as part of on orbit testing and we hope to have the spacecraft ready for services by the end of this year," he said.

    GSAT-16 has 24 C-band, 12 Ku-band and 12 Upper Extended C-band transponders that will boost public and private TV and radio services, large-scale Internet and telephone operations.

    It improves the national space capacity with 48 transponders joining 180 odd existing transponders with ISRO.

    Hit by capacity crunch, ISRO has leased 95 transponders on foreign satellites mainly for private sector users like TV broadcasters who have often complained of inadequate transponder capacity to meet their requirements.

    The transponder augmentation has become a pressing need, prompting advancement of GSAT-16 launch by about six months.

    Today's launch comes 11 months after the last Indian communication satellite — GSAT-14 — was flown in January this year.

    GSAT-15 is scheduled for launch in October next year.

    "I wish to inform that we will come back to Kourou with GSAT 15 spacecraft.It is at the advanced stage of integration at ISRO satellite center where we are conducting tests as per plans.

    That is expected to be ready for launch some time by third quarter of 2016," Shivakumar said.

    ISRO said the present orbit of GSAT-16 will be raised to Geostationary Orbit of about 36,000 km altitude through three orbit raising manoeuvres by the firing LAM engine.

    "Preparations are underway for the first firing, planned in the early hours of December 8. The satellite will be placed in the Geostationary Orbit by December 12 and subsequently the satellite's communication transponders will be switched on for in-orbit testing,"it said.

    India's rockets PSLV and the present GSLV do not have the capability to launch satellites of more than two tonne class, prompting ISRO to opt for an outside launch.

    ISRO is developing the next big launcher, GSLV-MkIII, which can put satellites of up to 4 tonnes in orbit.

    The Government in July, 2013 had given approval for GSAT-16 with a procured launch cost and insurance both amounting to Rs 865.50 crore.

    Ariane's payload lift performance is more than 10,200 kg., including a combined total of some 9,480 kg. for DIRECTV-14 and GSAT-16 passengers.

    The designated on orbit operational life of GSAT-16 is 12 years.

    In the coming days, the deployment of appendages such as the solar panels, antennas and three axis stabilisation of the satellite will be done.

    GSAT-16 will replace INSAT-3E, which was decommissioned a little prematurely in April.

    What are concrete bilateral projects in the space area?

    In fact there has been space cooperation between India and Russia since the 1960s, and then getting into the Aryabhatta project and launch of a few satellites from Russia. We also had a good cooperation in the cryogenic engine and stage.

    Currently, we are meeting soon with the Russian Space Agency in Delhi to discuss the areas for the future cooperation.

    India is planning the first human space mission. What are the phases of this project?

    India conducted a feasibility study during 2006 and 2007, and we were looking at a mission to put a two-member crew around an orbit around earth, keep them for a week and then bring them back safe to Earth.

    Some of the critical technologies required for the Human Space Flight are being developed, and one area we are getting into soon is a flight testing of the unmanned crew model, essentially to study the re-entry characteristics.

    Do you mean flight testing through the GSLV new mission?

    This is being done in the first experimental flight of the GSLV Mark-III, an advanced launch vehicle that we are developing for carrying 4 tonne class communication satellites into orbit. So in the experimental flight scheduled for December 2014, that is, just a couple of weeks from now, we are putting this unmanned crew model.

    Earlier India has had the first successful Mars mission. There are also plans for the second Mars Mission?

    Yes, so the first mission to Mars i.e. putting an orbiter around Mars was successfully done on September 24, 2014. Our current task is to make observations using the five instruments that are onboard Mars. We are looking at the possibilities of a future Mars mission.

    We have not decided whether it is going to be an orbiter or a lander but whatever we do next in this area will be a major scientific mission. Opportunities come once in 26 months and certainly we will not be able to avail for a major scientific project. So we’ll have a possibility to do this in 2018 or later.

    Are there any plans for India to have its own orbital stations?

    No.

    India successfully entered the market for commercial launch of satellites and became a competitor to the West. Do you feel any pressure from your competitors?

    No, I am not talking about competition but PSLV has a niche in the international market. There have been several inquiries, and we have launched satellites of 19 countries so far and some of them are heavy satellites and what is in the offing for the next two-three years are also major satellites. So there is a demand for launch of such satellites by PSLV.

    Are there any plans for India to enter the market for commercial launch of heavy satellites with GSLV? If yes, when?

    PSLV as of now has launched 40 foreign satellites and a few more are lined up for the launch in the coming years. There are inquiries about use of GSLV also going on at the moment. Nothing is finalised but they are in the discussion stage.

    Is IRNSS installation going on time? Are there any plans for its integration with any foreign navigation system, including Russian?

    At the moment India has a Regional Navigation Satellite System with seven satellites in an orbit of 36000 kilometres. We have already put in the orbit three satellites. Four more are expected to be in the orbit by 2015.

    We have international systems, for example GPS. So with GPS, we already have an activity here improving the positional accuracy of GPS signals and that project is called GAGAN, and it is already commissioned and certified. We are also having discussions with GLONASS and our progress in this area will become clearer after our discussions with the Russian Space Agency.

    What projects in the field of space exploration does India have in store?

    Space science missions are one of our priorities. So the Chandrayaan-1 and the Mars Orbiter Mission are part of that. By 2015, we are planning to have an astronomy satellite called ASTROSAT. It is a multi-wavelength observatory in space. Then we have a mission to Moon which is a lander-rover combination and then, we are also looking at the study of the solar corona that is called Aditya Mission. So these are lined up for the next three years in the area of science and exploration.

    There will be in 2015 an anniversary of Aryabhata launch. Are there any plans to commemorate this event?

    Yes, it is a very major milestone in India’s space science and technology and also a milestone in the cooperation between India and Russia. So we will discuss with the Russian Space Agency how to celebrate this.

    India is one of the leading countries in medicine. Are there any plans to develop space medicine?

    No, we are in the area of telemedicine that is using satellites for connecting a super speciality hospital with hospitals in the remote areas and islands. That is our priority at the moment.

    Will discuss our future projects with Russian Space Agency – ISRO Chief | Russia & India Report

    SRIHARIKOTA: India's space agency today launched its heaviest rocket ever - the 630-tonne, three-stage Geo-Synchronous Satellite Launch Vehicle Mark III. The mission will take the Indian Space Research Organisation or ISRO a step closer to sending astronauts to space.

    Here are 10 facts about the mission:
    1. The rocket, launched from Sriharikota in Andhra Pradesh, is 42.4 meters tall and costs about Rs. 160 crore.
    2. The rocket is capable of doubling the capacity of payloads India can carry into space. It can carry four tonne communication satellites. Once ISRO masters this rocket, India won't need expensive foreign launchers to send its heavy-duty communication satellites to space.
    3. On this flight, the rocket is being tested on how it performs while traveling in the atmosphere. Its first two stages are active rocket engines and the third stage, which consists of the cryogenic engine, is passive.
    4. The heavy-duty cryogenic engine necessary for this rocket is still being developed by ISRO. A full-fledged launch of the rocket can be expected in a few years.
    5. The GSLV Mk III is a new rocket design by Indian engineers and marks the beginning of what could be India's initiation into the ambitious human space flight programme. Its main passenger is an Indian-made crew module.
    6. The crew module will be unmanned, but the small room-sized cupcake-shaped satellite is capable of carrying two or three astronauts into space.
    7. In this flight, the crew module will be hoisted up to an altitude of about a 127 km above the earth. The crew module is also powered by its own engine and will be navigated and made to re-enter the atmosphere at a massive velocity. It will then be slowed down with massive parachutes, the largest ever to be used by India. The crew module will then make a splash down near the Andaman Islands in the Bay of Bengal.
    8. ISRO has proposed that it can fly Indian astronauts into space using an indigenous rocket from Indian soil within seven to eight years of getting the government's clearance for its astronaut programme.
    9. ISRO has sought around Rs. 12,500 cr for its human space flight mission. When it happens, India will become the fourth country in the world to have indigenous capability of sending humans into space.
    10. Russia, the US and China are the only nations to have the technology for this complex mission
