    Current satellites can be utilized for it.

    If you can see the movement of enemy missile being road transported or underflight, you are likely to be more prepared with interceptors.

    Satellite guided air defence systems that even integrated together, like CIWS & Interceptors can destroy any incoming object, from cruise to ballistic missile at any distance, even if many come simultaneously. But we need at least a decade to be perfect here. Specially, with our anti ICBM interceptor in development.
    It will also be used as ASAT missile.

    Can't the current Satellites be equipped be CO2 Laser to destroy ICBMS in space?

    As we are improving with DEW weapons I think it can be possible.

    Many countries have confirmed and unconfirmed ASAT capability.

    And Imagine what would be the weight of such satellite. A heavier rocket will be needed. If ever this satellite falls down from orbit, you will need a much powerful interceptor to destroy it otherwise accident gonna be fierce.
    May be but not anytime soon.

    From ISRO side but most likely because of slots.
    Managing so many things isn't easy.

    Bangladesh inks agreement with India to join the South Asia Satellite initiative

    Bangladesh has signed an agreement with India to formally join New Delhi’s ‘South Asia Satellite’ initiative, through which the Indian Space Research Organization (Isro) will launch a communication satellite for serving the South Asia region. The agreement was inked by Bangladesh Telecommunication Regulatory Commission (BTRC) Chairman Shahjahan Mahmood and Indian High Commissioner Harsh Vardhan Shringla on Thursday, bdnews24 reported.

    The High Commission said Bangladesh has now formally agreed to join the ‘South Asia Satellite’, an initiative of the Indian government. India, through Isro, will launch a 2 ton class communication satellite with 12 Ku band transponders (36 Mhz each) using Isro’s Geosynchronous Satellite Launch Vehicle (GSLV Mk-II) for serving the South Asia region. The applications proposed under the satellite system include tele-education, tele-medicine and inter-government networks, emergency communication for disaster situations, television broadcast and DTH television services.

    There is a potential for each participating country to use a dedicated transponder with capacity of 36 to 54 Mhz for its own internal use. Each country would be responsible for content generation and its use, the High Commission said in a statement. All South Asian countries, except Pakistan, will be part of this unique project binding the region in “a cooperative and collaborative endeavor for the benefit of the people of the participating countries”.

    Prime Minister Narendra Modi earlier announced the launching of the satellite during the 2014 SAARC Summit in Kathmandu as a “gift to India’s neighbours”. “This satellite is a reflection of India’s commitment to the development of the South Asian region and an expression to share its expertise and technology for the benefit of the region,” the High Commission said. The inking of the agreement comes ahead of Prime Minister Sheikh Hasina’s visit to India next month.

    ISRO offers space tech to electric vehicle makers in India

    [​IMG]


    Indian Space Research Organization could soon help Indian e-bikes overcome their biggest drawbacks — low mileage per charge and limited speed.

    Costing between Rs 35,000-50,000, most of these bikes have a top speed of 25 km per hour and a range of 30 to 50 km per charge.

    That could change soon, thanks to the incorporation of space technology from ISRO.

    IT’S ALL IN THE BATTERY

    The primary reason for the limited speed and range of electric two-wheelers in India is poor battery capacity.

    Most of these bikes come with 1000 watt-hour batteries. That means the bike’s motor can consume 1,000 watts for one hour before the battery is completely drained.

    However, to achieve a speed of 50-60 km/hour — which is required to flow along with petrol-fueled traffic — you need a motor that consumes about 1,650-2,500 watts — depending on the weight of the bike.

    However, if the motor consumed 2.5 kW, the battery will be exhausted in 24 minutes. So even if you are traveling at 60 km per hour, you would have traveled only 24 km by the time the battery runs out.

    In practice, due to braking, inclines and speed variations, the effective range will be about 20 km on highways, which is too less for most users.

    As such, manufactures do not put 2.5 kW motors on such e-bikes.

    Instead, they go with much smaller motors in the 250 to 500 watt range — which have only one-tenth to one-fifth of the required power need to travel at a speed of 60 km per hour.

    While this helps in regulating power consumption and improving the range slightly, the maximum speed drops to 20-30 km per hour because of the weak motor.

    BIGGER BATTERY

    The obvious solution to this problem is to increase the battery capacity, but this creates a different problem.

    With the widely used lead-acid batteries, each 50 watt-hour of battery capacity adds 1 kg to the weight of the battery.

    So, if you want a 2,500 watt-hour battery which would power a 2,500 watt motor for 1 hour and give you a top-speed of 60 kmph and a range of 60 km, you end up with a battery that weighs 50 kg.

    This is a significant problem for the industry as the electric scooter itself weighs only around 50 kg and putting a battery weighing 50 kg on such a vehicle creates various structural problems.

    Besides, the speed and the range of the vehicle will be noticeably impacted by the weight of the battery.

    ISRO TO THE RESCUE

    This is where ISRO is pitching its in-house battery technology.

    Since the weight of the battery has to be kept minimum for space applications such as rockets and satellites, India’s space agency has spent considerable amount of time thinking about ways to reduce the weight of power units.

    It has developed its own light-weight batteries — based in lithium-ion technology — that deliver far more capacity compared to the lead-acid batteries in use today.

    To demonstrate, the agency, along with Automobile Research Association of India, has created a test bike with a 2,400 watt-hour battery inside it.

    While a lead-acid battery of this capacity would have weighed about 48 kg, ISRO uses lithium-ion technology to keep the weight down to about 12 kg.

    The bike is powered by a motor of around 1,500 watts and can achieve top speed of 50 km per hour. Instead of the usual maximum range of 30-50 km per charge, the test vehicle delivers a range (mileage) of 98 km under optimum conditions.

    Both the speed and the range can be improved with further optimization.

    The closest competitor to the test vehicle is Hero MotorCorp’s Photon. It also comes with 1,500 watt motor, but can achieve a top speed of only 45 km/hour because of the heavy lead-acid battery inside it.

    It is powered by a 1,584 watt-hour battery, which alone should weigh close to 32 kg, going by the traditional weight to capacity ratio.

    Due to the heavy battery, the Photon travels only 31.57 meters for each watt-hour capacity contained in its battery. In comparison, ISRO’s bike travels 40.83 meters for each watt-hour capacity inside its battery.

    In other words, if it was ISRO’s battery inside the bike, chances are that the bike would have a range of 65 km instead of 50 km and the top speed too would have been 5-10 km/h more than 45 km/hour.

    PRICE IMPEDIMENT

    However, ISRO’s technology alone may not be enough to enable companies like Hero MotoCorp to make the switch from lead-acid batteries to lithium ion.

    While ISRO can license its manufacturing technology for very low rates to Indian manufacturers, there is a second factor at play — the cost of lithium, the key ingredient.

    At present, due to high prices for the metal, the cost of producing lithium ion batteries is about Rs 11,000 ($165) per 1000 watt-hour — and that too at a large scale.

    As such, the 2,400 watt-hour battery found inside ISRO’s test bike would cost about Rs 26,000 if made today at a large scale.

    Assuming that the overall cost of the bike has remain in the Rs 50,000 bracket, that leaves only Rs 24,000 for the rest of the bike.

    In comparison, traditional lead acid batteries of the same capacity can be purchased for just Rs 12,000.

    CHEAPER IN THE LONG TERM

    Despite this, for regular bike users, a lithium ion unit is still far more economical.

    A traditional lead-acid battery can only be charged and discharged about 200-250 times, which means they will have to be changed every 10 months or so for daily users.

    However, lithium ion batteries can be recharged 1,000 to 5,000 times depending on their quality, which means that they can last 5 to 15 times as long as a lead acid battery.

    As a result, if the vehicle is used for 5-10 years, a lithium ion battery would require a one-time investment of Rs 26,000, while the other one will involve a cost of Rs 60,000 to 1,20,000 for buying 5 to 10 units during the bike’s lifetime.

    Another promising development is the huge investments being made by Tesla Corp and Chinese companies in creating huge factories to bring down the cost of lithium-ion batteries.

    These firms expect the price to dip to $100 per kWh, which would bring down the price of a 2,400 watt-hour unit to Rs 16,000, comparable to the Rs 12,000 price of lead-acid.

    However, neither the Indian government nor India companies have any plan to invest in making such batteries on a large scale in India, and the country may have to import the units from China and the USA.

    Isro will allow companies to obtain lithium-ion battery tech

    NEW DELHI: The government has asked Indian Space Research Organisation (Isro) to allow manufacturers interested in producing indigenous lithium-ion batteries, including those from private sector, to obtain the technology for its mass production. Isro will now come up with a framework to make this process smooth.

    The Vikram Sarabhai Space Centre under Isro has developed indigenous technology to manufacture such high-power batteries for automobiles and e-vehicles and their feasibility tests in vehicles have been successful.

    Over half a dozen major automobile companies, battery manufacturers and public sector undertakings have already approached Isro. Mahindra Renault, Hyundai, Nissan, Tata Motors, High Energy Batteries, BHEL and Indian Oil have shown interest in producing the indigenous lithium-ion batteries.

    Union road transport minister Nitin Gadkari had sought Isro's help to develop indigenous technology for lithium-ion batteries so that their prices are within the reach of Indian customers.

    Isro had earlier developed similar batteries for satellite and the launch vehicle applications.

    The government has set an ambitious target for pushing more use of electric vehicles to reduce air pollution, which has become one of the biggest health concerns. Batteries are the key component of any electric vehicle. At present, all lithium-ion batteries are imported and it's very expensive.

    Such batteries have high-power, but these weigh less and their volume is much less as well in comparison to conventional batteries.

    Sources said Isro and BHEL are likely to finalise an MoU soon for manufacturing such batteries.

    "The cabinet secretary has asked Isro to create a framework for enabling even interested private players to obtain the technology for mass production.
    Only one agency producing them will not be enough. The cost will come down only when we will have huge production to meet the demand," an official said, who was present in the meeting. Gadkari chaired this meeting.

    Government documents show the cost of lithium-ion batteries is high because of small volume of procurement. Bulk procurement and mass production can reduce the cost by 80%, which is key to push demand.

    ISRO announces launch of South Asia Satellite on May 5; Pakistan's name dropped

    New Delhi: May 2017 is all set to witness the launch of the Indian Space Research Organisation's (ISRO) 'South Asia Satellite' that aims to benefit all the countries in the region. Pakistan will not be a part of the project.

    In a telephonic interview with PTI, ISRO chief AS Kiran Kumar confirmed the agency's plan saying that, “It's going up in the first week of May.

    According to ISRO sources, the launch of this communication satellite (GSAT-9) is scheduled for May 5 on board the space agency's rocket GSLV-09 from Sriharikota spaceport.

    Kiran Kumar said the satellite, with a lift-off mass of 2,195 kg, would carry 12 ku-band transponders.

    "Pakistan is not included in that. They did not want (to be part of the project)," he said.

    Sources said the satellite is designed for a mission life of more than 12 years.

    During the 2014 SAARC Summit in Kathmandu, Prime Minister Narendra Modi made an announcement about the satellite, calling it a “gift to India's neighbours.”

    Formerly named 'SAARC Satellite', the satellite's name was later changed to 'South Asia Satellite', after Pakistan was dropped from the list of nations taking part in the project.

    "Basically, it (the satellite) is meant for providing communication and disaster support, connectivity among States (countries of South Asia region). It will provide a significant capability to each of these participating States in terms of DTH, certain VSAT capacity plus linking among the states for both disaster information transfer and also in terms of library type of things," he said.

    "So, there is a significant amount of inter-linking possible among the States (these countries)," Kiran Kumar said.


    According to ISRO officials, there is a potential for each participating country to use a dedicated transponder with a capacity of 36 to 54 Mhz for its own internal use.

    Each country would be responsible for content generation and its use, they said.

    ISRO to launch first developmental flight of ‘game-changer’ rocket next month

    Indian Space Research Organisation (ISRO) plans to undertake the first developmental flight of a “game-changer” rocket capable of launching four-ton class of satellites from Sriharikota spaceport next month, said its Chairman A S Kiran Kumar. ISRO rockets (launch vehicles) at present have the capability to launch satellites up to 2.2 tons; it depends on international launchers to orbit satellites heavier than that.

    “Next month, we have scheduled the launch of GSLV-Mk III-D1”, Kiran Kumar told PTI.

    The Bengaluru-headquartered space agency plans to undertake the second developmental flight within a year.

    “By the time two developmental flights are over, we will be working towards making more launches so that it (GSLV-Mk III) becomes operational”, he said.

    ISRO views operationalisation of this rocket as a “game-changer” for it, he said.

    “Once we build our own four tonne capacity, we will be able to significantly reduce our launch from outside; then we are also looking at building satellites within that four-tonne capacity, so that you can do all the launches within the country,” Kiran Kumar said.

    The GSLV-Mk III-D1 launcher would carry GSAT-19 satellite which has a mass of 3200 kg.

    The satellite would carry Ka and Ku band payload along with a Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of the charged particles and influence of space radiation on spacecraft and electronic components.


    http://indianexpress.com/article/in...ht-of-game-changer-rocket-next-month-4619599/
    The satellite would employ advanced spacecraft technologies including bus subsystem experiments in electrical propulsion system, indigenous Li ion battery and indigenous bus bars for power distribution, among others.

    India Plans to Use Moon Dust for Energy Needs

    20:00 20.04.2017
    663762
    A scientist from the Indian Space Research Organisation (ISRO) has stated that India is working to exploit natural resources on the moon to power the country’s energy requirements by 2030.

    [​IMG]

    New Delhi (Sputnik) – ISRO is working on mining lunar dust, which is rich in Helium, and transport back it to India, said Dr Sivathanu Pillai, an ISRO scientist who earlier worked as the chief of the Indo-Russian venture, BrahMos Aerospace.

    All of India’s energy requirements could be met through Helium 3 mined from the moon. By 2030, this processing target will be met, he said while delivering the valedictory address at the three-day Observer Space Foundation-Kalpana Chawla Space Policy Dialogue in New Delhi, organized by Observer Research Foundation, a private think-tank.

    According to Pillai, the upper layer of the moon’s surface, Regolith, has abundant Helium 3 to meet the energy requirements of the entire planet and not just India. An isotope of Helium, Helium 3 can fuel nuclear reactors to provide an enormous amount of power without any harmful carbon emissions or radioactive products.

    It is dispensed by solar winds on the moon’s surface and gets absorbed there due to a lack of magnetic field. Earth’s magnetic field prevents the solar Helium 3 from reaching the surface. Helium 3 is abundant in the moon’s soil by at least 13 parts per billion (ppb) by weight, according to NASA’s website.

    India is not the first country to declare its intent to mine the lunar surface. Both Russia and China have plans to tap resources on the moon.

    In fact, Russian company Energia aims to mine Helium 3 by 2020, while China’s is going to launch an unmanned lunar Chang’e 5 later this year, with the purpose to bring lunar soil with Helium 3 back to the Earth.

    But is ISRO's plan realistic despite the Indian space agency's recent achievements such as sending more than 100 satellites at one go? Experts say it is not unrealistic but will require serious efforts and investments.

    "ISRO's 2030 target at present looks very realistic considering no other country has been able to meet their own deadlines. No country has been able to launch a manned mission to the moon after the Apollo missions. But, ultimately, everything depends on how the technology evolves and is implemented. And here we are talking about sending manned or unmanned spacecraft to the moon, mining lunar surface and bringing the soil back to the country and processing it for energy production in a cost-effective manner," Group Capt. Ajey Lele (Retd), Senior Fellow, Institute for Defence Studies and Analyses told Sputnik.
