The raw truth is that when Indians make huge leaps in high tech industries,,the british "royal" ass starts burning with envy. Someone said above that they still have "neo Colonial' mindset and is still in denial about the changed world.

I certainly don't agree to their view of closing down India's space and missile program but their criticism of India's social condition is justified.We shouldn't be so thick skinned that we stop listening to other's criticism.
Criticize the white men on NATO exeditions and their Ukistanization by Pakistan in UK. Them shouldn't be so thick skinned that the stop listening to other's criticism on these.

As far as ISRO is concerned,their number 1 priority should be to develop fuel efficient and environment friendly modular rockets with higher payload capability as the current PSLV and GSLV series rocket are light launchers.
Only then we can ear a larger pie of the 300 billion $ launching market.
Dont worry about it ISRO knows what they are doing..they are upping their capabilities in Stages.
$300 BILLION mark cannot be achived in a day or an year...it takes time and it needs persistence which ISRO has. Dont try to make an issue that doesn’t exsit cuz they are doing it in stages and capabilities will be achieved in near future.

When I was a child, Doordarshan used to broadcast University Grants Commission used to broadcast educationl TV programs sourced from both India and foreign universities and institutions. At that time there was a long series on the Voyager Space probes. I used to feel envious of the science involved in those projects and the extreme extent to which NASA was leveraging little pieces of technologies. Today that kind of science is being done in ISRO. While NASA is high on the American Dream - Got money, flaunt it. Its not like all these probes have any real use. What is the point in being the first to know what is there on the other side of this planet and that satellite or being the first to know how the xyz physical entity in cosmos behaves or being the first one to go to moon. But these kinds of things give an idea to the next generation that expending money is not the only parameter to measure success. Actually doing the most difficult thing considering your 'capabilities', properly, is the only real measure of success. Any idiot can expend money esp. if its debt money and esp. if the world has lent that money without its wishes.

ISRO is doing good in expanding the envelop for us Indians. Keep it up ISRO.

ISRO tests home-grown cryogenic rocket engine for 800 seconds

Bengaluru, July 20: The Indian Space Research Organisation (ISRO) successfully ground-tested a home-grown developed ‘high thrust cryogenic rocket engine' for duration of 800 seconds. ISRO sources said that the state-of-the-art cryogenic rocket engine, generating a nominal thrust of 19 tonnes, was endurance hot-tested on July 16, 2015 at the ISRO Propulsion Complex (IPRC) in Mahendragiri.

Situated in Tirunelveli District of Tamil Nadu, the IPRC Mahendragiri is equipped with most modern facilities for realising the cutting edge technology products for ISRO's space research programmme. The latest test was for a duration of approximately 25 per cent more than the engine burn duration in flight. The engine once operational will be used for powering the Cryogenic stage (C25), the upper stage of the next generation GSLV Mk-III launch vehicle of ISRO, capable of launching four-tonne class satellites. This high-performance cryogenic engine was conceived, configured and realised by Liquid Propulsion Systems Centre (LPSC), the lead centre of ISRO responsible for developing liquid propulsion systems for various space programmes.

High-altitude test planned
The performance of the engine closely matches with the pre-test prediction made using the in-house developed cryogenic engine mathematical modelling and simulation software. Prior to engine realisation, a series of subsystem level tests were carried out to independently evaluate the design of major subsystems like the turbopumps, thrust chamber, gas generator, flow control components, etc. Based on the confidence gained, the integrated engine testing was initiated. As part of the C25 Stage development, further tests are planned in high-altitude conditions and in Stage configuration, prior to the flight stage realisation.

Engine design a total in-house
effort ISRO says that the engine design was totally an in-house effort with experts from fluid dynamics, combustion, thermal, structural, metallurgy, fabrication, rotor dynamics and control components working together. The fabrication of major subsystems of the engine was carried out through Indian industries. ISRO says that the recent successful endurance hot test of the first high thrust cryogenic engine is the 10th test in a series of tests planned and executed as part of the development of the engine employing complex cryogenic technology.

Hmmmm I just wish the GSLV-III would have been flight tested this year instead of next. Anyway I guess GSLV-II is the priority currently.

India May Next Step On Venus, Mars & An Asteroid: ISRO





With a new friendly phase in Indo-US ties, Indian Space Research Organisation (ISRO) looks forward to deep space exploration mission where India may next step on Venus, Mars, and an asteroid.

Several robust missions are being explored by ISRO to make the impossible happen in space.

According to well-known science writer Pallava Bagla, “The unthinkable is already happening in space, India and America are together planning to explore the last unknown frontier. Until recently India was untouchable.”

Venus, Mars, and an asteroid all could be the next big destinations that India will be exploring. The Indian Space Research Organisation (ISRO) is now embarking on a new planet-hunting endeavour. There are indications that the United States of America will be working with India in this ‘deep space exploration’.



As per ISRO’s own plans, in the next few years another robust mission to planet Mars is being planned by ISRO. A possible flyby to an asteroid is likely. A small satellite aptly called ‘Aditya’ will keep a constant eye on the ever-changing moods of the Sun.

Speaking to students of Indian Institute of Technology, Chennai Richard Verma, Ambassador of USA to India sprung a surprise by saying, “We look forward to path-breaking work between NASA [National Aeronautics and Space Administration] and ISRO on deep space exploration to Mars and beyond”.

Till 2005, ISRO was a total pariah kept under full technology denial and sanctions were in full force but a decade later the chill has gone and relations have thawed, now hand in hand both want to fly ‘where no man has gone before’.



If Pluto was the target for the American space agency through its mission ‘New Horizons’, the Indian space agency is also setting its goals to explore the Solar System to its limits. On ISRO’s wish list ‘a technology demonstration mission or a flyby to the outer solar system’.

The current ISRO chief, who played a key role in the success of Mangalyaan says, “for the next planetary mission, we are looking at opportunities whether it is a repeat Mars mission, or Venus mission or even an asteroid mission’ revealed Kiran Kumar, Chairman, Indian Space Research Organisation (ISRO).

Exploring Venus could be the next logical step as India has already been to Mars. It is Earth’s neighbour and if all goes well in a few years an Indian rocket will lift off and head towards the inside of the Solar System.



Until date only Russia, America, the European Space Agency (ESA) are the ones to have successfully reached Venus. In 2010 Japan tried but failed. Can India make global history once again by becoming the first Asian country to reach Venus. Repeating a moment in history when India’s Mangalyaan in its maiden attempt itself reached the Red Planet a feat not achieved by any other country.

Venus is considered a twin of Earth and yet very little is understood about this terrestrial planet. It is almost the same size that of Earth but it has a hugely dense atmosphere made up mostly of carbon dioxide and being closer to the Sun it has an average temperature of about 460 degrees Celsius.

U R Rao, former chairperson of ISRO and head of the committee that decides on scientific missions has long expressed a desire that India should ideally soon head to Venus.



It is believed by experts that Venus in a way resembles what could be the ultimate fate of Earth if run-away release of carbon dioxide goes on unabated and the climate continues to change with carbon dioxide being amassed in the atmosphere.

Kumar says there are many things to be learned at Venus like trying to figure out ‘why does the atmosphere of Venus rotate in the opposite direction’.

Some of these future planetary missions would need bigger rockets and towards that Kumar says India’s indigenously made Geosynchronous Satellite Launch Vehicle Mark-II (GSLV Mk-II) is probably going to be the preferred vehicle as it has ‘superior capabilities’. The almost 50-meter tall rocket that weighs as much as 414 ton is capable of hoisting a 2500-kilogram satellite on interplanetary voyages.

India has had hugely successful interplanetary missions, the most recent being Mangalyaan that reached the Martian orbit in 2014 and continues to operate with vigour sending back scientific data to India.

The Mars Orbiter Mission or (MOM) was launched using the Polar Satellite Launch Vehicle (PSLV). Kumar says ‘we have demonstrated the overall capability that we can go up to Mars with a minimal launcher using the PSLV’.



Therefore, a repeat mission to Mars is very likely but with a heavier satellite where scientific instruments would get priority. Kumar says ‘the next mission will be science driven.’

A recent document submitted by ISRO to the government enlists what is going through the minds of the scientists and engineer at ISRO: ‘Initiatives towards undertaking a Mars orbiter and lander mission during 2018-launch opportunity— identification of scientific payloads.

Exploration of Mars surface features viz. morphology, topography, mineralogy and Martian atmosphere’ all can be studied in Mangalyaan-2. Kumar says no final decision has been taken on the next Mars mission and no date has been fixed. Kumar is sure that Mangalyaan-2 will be a science mission unlike the first Mangalyaan, which was a ‘technology demonstrator’.

India already has a second visit to the Moon planned for 2018 through Chandrayaan-2 that will include an orbiter, lander and a rover on the lunar surface. This Rs 500 crore mission is already being put together in Bengaluru and it will be launched using the GSLV Mk-II.

According to ISRO it would ‘further our understanding of origin and evolution of the Moon with improved versions of Chandrayaan-1 instruments for imaging, mineralogy and chemistry; addition of alpha and neutron spectrometers in the orbiter. Studies of lunar radiation environment including solar wind interactions’.

Beyond Chandrayaan-2 ISRO seeks to plan for ‘lunar sample return missions from the polar region of moon and a possible establishment of lunar observatory’.



ISRO in its plans also lists ‘a remote sensing asteroid orbiter & comet flyby: with the science goal of understanding the evolution of asteroids and comets, early solar system processes, meteorite-asteroid connection, physical and chemical properties of asteroid and cometary material.’

India is also seeking to undertake a visit to an asteroid and there is every possibility that India may cooperate with the American space agency, NASA on its asteroid initiative where it will try to re-direct or even harvest an asteroid. India with its demonstrated capabilities of undertaking low-cost high-value inter-planetary travel – Mangalyaan at Rs 450 crores was the cheapest mission ever – offers great opportunities for NASA to work with.

A possible win-win for both sides where space science would be the biggest gainer.

Indeed,everyone should be open to criticism.I don't understand why we take their criticism so personally.

Had the Americans listened to their critics,there would have been no man in the moon,no space shuttle,no space station and probably no space program too.

I am not criticizing,as an engineer i look at things objectively and rationally.As i said vehicle development should be the number one priority because the current PSLV and GSLV will give us very little business.

Quality control should be next on the list.This would become a major issue with increase in number of launches.

why cannot we have a private company (large corporation) build PSLV (initially) ... with ISRO focus on its more technical advanced beauties (including satellites and interplanetary systems)

we are launching (officially) it seems that the demand is much higher and we need to launch more often and faster

A lot of Rocket parts are made by private companies like Godrej,L&T as well as government companies like HAL.
ISRO simply assembles it at SHAR.

Appreciate the response - would love to see a alternative (e.g private power house) assemble the pslv at its own launch pad. Surely We have come a long way and isro is doing well but it needs to let go of pslv. We need to also launch and develop more and capacity if isro is such. We also need to exploit and build up system. Isro also needs to move more advanced and heavy lifting and more interplanetary and leave pslv sub 2 ton stuff to another.

Pslv still is relevant because of its track record and also efficeny and future use of small and smaller more compact satellites. Also sprrading technical knowhow learned of pslv from isro to another will give huge benefit inti yhe system like make in india. You have rightly pointed out private involvement but isro still have major (time including and resource including) involvement. surely we can have isro give and outsource its role currently to a private player

I don't forsee any Indian private player getting involved in the launching business atleast for the near future.It's because this is a hugely risky affair financially and there is no insurance.A single loss of rocket means a loss of no less than 500-600 crores. That is why you don't see so many private launching companies worldwide.

Besides that, PSLV wouldn't give big revenues because it's a light launcher,more importantly it's a complicated 4 stage vehicle with alternate solid and liquid stages unlike falcon 9 which is a much simpler 2 stage vehicle with similar kind of engines.

The more complex the vehicle,the bigger headache it is to manufacture and operate.


PSLV and GSLV were born during the technology denial era of the 90's.The lack of advanced technology forced ISRO to compensate by using older technology.

I appreciate response also understand the thought process you are advising. Sorry for the long post below:

I would still like to see private industry take this PSLV on. I find it most ideal because like you have mention we are having a eco system already with many private industry players supplying the PSLV modules. I am only advocating the role of ISRO be given to private industry conglomerate (it can even be ISRO equity stake of 30%+). We will not have two different power centers developing because ISRO will have overall ownership still. What is ISRO doing with PSLV now - What is left to give to private industry. One is the launch pad and integration you mention - we can get that for private industry conglomerate. Why we cannot have a launch pad away from ISRO managed by this conglomerate (i would like to label the Indian United Launch Alliance). We need to have such contingency in place any way.

For primary reason it will allow and spare up ISRO and make it focus on more advanced technology and not be forced to use and manage only older technology like you accurately mention. I also dont think PSLV is redundant because it is reliable and also we have grown it into the system. We can probably make it more efficient and productive.

Also.

If you look at the timetable and demand for space rocket launch we can do much more. We are hearing about increasing the capacity of ISRO but why not think about having extra capability.

For example launching a satellite for SAARC i was reading and we had to look at a timetable to see when we can. That was funny. And next i thought why only one timetable on offer and why the alternative is a foreign service provider. I thought we have how many launch pads.

We need to develop additional advanced space industry into the system where it is currently ISRO only. This would create extra employment for brilliant leaders and also additional skills and know-how. This can supplement ISRO easily and dare one say provide good synergy for ISRO. Dare i say people leaving ISRO can have (consultancy) work after they leave ISRO.

Having older technology that works to be used primary to set up this "private" industry is appropriate and it is best. It can still have ISRO ownership and review since ISRO will be the customer.

I dont see how we cannot get a economic model set up where ISRO promises [x] of PSLV over [y] years to this private industry conglomerate. ISRO can still have ownership. But these brilliant chaps at ISRO can give their attention on more advanced stuff. ISRO can be paid royalty and license fees (more on having upgraded benefits to ISRO).

Who knows this private industry conglomerate after they master the PSLV might come up with their own falcon X but they would need a start and launch first and having a promise of [x] of PSLV over [y] years would be incredible for industry.

One spike i see is that private industry pays more to government service providers. No issue that needs to be placed into the system. We need to stop thinking government is run by poor and also benefits are poor. Upgrade the benefits to ISRO !!

One talks about economics. We need to stop thinking that launch of PSLV does not provide economic benefits inside India and we only get money from outside. Government of India is a customer and pays ISRO. We also have india private industry paying ISRO.

Talking about Insurance. Everyone knows before 26/11 no one used to talk about Terrorism insurance in India now everyone has it and you can see and read about how it was developed with with Insurance providers here in India (no one wanted to do it in the first place for fear of big payout). We also have the nuclear liability insurance how we got it done. Insurance can be profitable for example if a indian company had offered insurance to PSLV they would have made a lot of money for it has 20+ successful launches. Also one needs to move away from thinking having insurance brings about loss. A insurance company will always find the blame why and reduce its loss. This only makes the systems better because the suppliers to PSLV will make sure it is without negligence (i am wishing people understand this principle). A bit like terrorism insurance having it meant that users had better security apparatus installed because part of the insurance terms were such and wanted to avoid being negligent. But surely insurance costs rise. And that is due to unexpected reasons and events. But that can be managed because we are having a suitable government instilled insurance system here in india and it is not about making profits only because this will be a important national project.

500-600 crores we need to start thinking it is not a big thing !! I find it ridiculous why we need to limit our thoughts and we need to start thinking much bigger. 5000-6000 crores loss we ought to take on.

https://en.wikipedia.org/wiki/North_American_XB-70_Valkyrie

We have to have a government led approach to make private industry take on big projects!! fear of failure and costs move away from the capability and success we will get by having such eco-system in place. PSLV is perfect right now for us. Its complexity is a wonderful opportunity to develop and expand the eco-system. It is like a gold ready to be melted and given to someone else.

A wise man once said : "Pessimists of the gloom and doom variety as you will always find the West to be superior since it is inbred inferiority that speaks."

I agree.

For all of the so called less complexity of Falcon-9 it has failed in its mature launches (18th launch). That means they still are not clear as to what they are launching. While the PSLV had failed in its early launches where failures are experienced by 3/4th of all rocket types. 1 failure out of 17 vs. 1 failure in 30. You decide. Whether the so called less complex tech is better or the better understood tech is better.

For all of the so called less complexity of Falcon-9, it also has had one orbital injection failure (aka partial failure), just like PSLV. Both having this kind of failures in initial launches.

For all the so called less complexity of Falcon-9, the goddamned thing has 9 engines in the first stage itself. One single engine going astray will give you a headache that 10 ICBMs cannot. Falcon-9 weighs something like 500 tons.

And lets not even talk about the ability to support multiple payload injections.

Reality is Falcon-9 is just as complex in terms of management as PSLV. Different kinds of complexities but still complex. And in all these complexities the ISRO team understands its product better than the Falcon team. In any case, had we not been denied collaboration with Russian launch agencies, by the Americans, I may add, we would have had our own full fledged cryogenic tech by now and given the attitude of Indian researchers, that too would have been as well understood as the PSLV.

Your S&T is limited by what you understand. And brochures do not help your understanding, one bit.

I am not trying to demean our capabilities,ISRO is doing best with whatever resources are available to it.

Having said that success rate PSLV and Falcon 9 cannot be directly compared.

Pslv has been launched only 30 times since 1993,thats nearly 1-2 launches a year on an average where as falcon 9(v1.1) has been launched 14 times in less than 2 years.

When you have only one or two launches in an entire year,quality control will not be a major issues as you have the whole year to inspect the vehicle and components thoroughly,in contrast the falcon 9 is being launched nearly every other month.Only in the past 2-3 years has ISRO started launching 3 rockets a year.

The performance can only be compared when ISRO starts launching PSLV 8-9 times a year.

This is what it will be carrying.

http://isp.justthe80.com/space-applications/communication-satellites/gsat---6

The S-band GSAT-6 satellite features a 6-m diameter antenna to facilitate communication from anywhere using a handheld device. (Typically, satellite communication is facilitated by a parabolic ground antenna and signal processing box.)

The satellite hosts 10 transponders - with five special transponders for multimedia services. It has CxS and SxC transponders. The S-band up and down links would have high G/T and Effective Isotropic Radiated Power to be able to communicate with mobile instruments. This is achieved by using 5 high power 235 W Traveling Wave Tube Amplifiers and an indigenously developed high gain 6m Unfurable Antenna.

And after that the next logical step would be this:

pibmumbai.gov.in/scripts/detail.asp?releaseId=E2015PR1971

NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a dual frequency (L & S Band) Radar Imaging Satellite. In this joint mission, JPL/ NASA will be responsible for design & development of L-band SAR, 12m unfurlable antenna, GPS system and data recorder. ISRO will be responsible for design & development of S-band SAR, Spacecraft Bus, data transmission system, Spacecraft integration & testing, launch using GSLV and on-orbit operations. The aim and objectives of NISAR mission are:

• Design, Develop and launch a Dual frequency (L and S Band) Radar Imaging Satellite.

• Explore newer application areas using L and S band microwave data, especially in natural resources mapping & monitoring; estimating agricultural biomass over full duration of crop cycle; assessing soil moisture; monitoring of floods and oil slicks; coastal erosion, coastline changes and variation of winds in coastal waters; assessment of mangroves; surface deformation studies due to seismic activities etc.
