Any updates on GSLV 3 launch schedule?
AFAIK, it was supposed to be this month. But no update since month started ...........Any updates on GSLV 3 launch schedule?
Must be slated to another then. We would have got update otherwise.AFAIK, it was supposed to be this month. But no update since month started ...........
The upper stage of GSLV MK-III vehicle is powered by Cryogenic Engine (CE)-20 which develops a nominal thrust of 186.36 kN with a specific impulse of 442 seconds in vacuum. The engine operates on gas generator cycle using LOX / LH2 propellants combination. The major subsystems of the engine are thrust chamber, gas generator, LOX and LH2 turbo pumps, igniters, thrust & mixture ratio control systems, Start-up system, control components and pyro valves. The fifth hardware of CE-20 integrated engine designated as E6 is earmarked for GSLV Mk-III M1-Chandrayaan 2 mission.
The flight acceptance hot test of E6 engine was successfully tested for 25 seconds at High Altitude Test facility, ISRO Propulsion Complex (IPRC), Mahendragiri on October 11, 2018. The test demonstrated steady state operation of engine. The performance of all engine subsystems were observed to be normal during the hot test.
Megha-Tropiques satellite was built by ISRO and CNES as a Joint Venture. The satellite is meant to study water cycle and energy exchanges in tropical region for weather prediction and climate research. Megha-Tropiques was launched on 12th October 2011 from SDSC, Shriharikota. The satellite has successfully completed seven years of on-orbit observations with four Science instruments on board, namely, MADRAS, SAPHIR, SCARAB and ROSA. Megha-Tropiques provides scientific data on the contribution of the water cycle to the tropical atmosphere, with information on condensed water in clouds, water vapour in the atmosphere, precipitation, and evaporation.
All science instruments provided valuable data to the user community. Many national and international papers have been generated by utilizing these datas. The Global response for the Announcement of Opportunities for science data utilisation of the instruments on-board Megha-Tropiques has been good and is increasing with time.
If the tickets are for sale. I'd buy one for the adorable boy's launch.ISRO should not get into this gallery buisness. Better hand it over to guys who oversee planetarium and science exhibits.
Scientists should be least worried about common people being able to view launches.
ISRO is not doing it itself. They have released an RFP for this.ISRO should not get into this gallery buisness. Better hand it over to guys who oversee planetarium and science exhibits.

Yes, Sachin'' inspiration was 1987 world cup as ball boy. He was a good player by that time thoughISRO is not doing it itself. They have released an RFP for this.
Moreover its a great initiative on part of ISRO. This would help us garner new talents among our new progeny. A launch view in real is much more impressive to young minds then a broadcasted one in TV.
Not everyone is a scientist in ISRO, besides watching something like this live not only for kids but plenty of us machine lovers is a dream come true.:biggrin2:ISRO should not get into this gallery buisness. Better hand it over to guys who oversee planetarium and science exhibits.

BENGALURU: Indian Space Research Organisation (ISRO), which has set an ambitious target of launching two satellites every month from October this year and throughout 2019, appears to have hit a bottleneck in the very first month of the plan. While two satellites were scheduled for launch during the month of October, sources say the launches were highly unlikely due to integration delays.
ISRO chairman R Sivan, in a briefing held earlier this year, had announced that the agency will launch two satellites every month as it had launch orders for 50 satellites already, over a period of three years. GSAT-29 aboard Geosynchronous Satellite Launch Vehicle (GSLV) MK-II and Polar Satellite Launch Vehicle (PSLV) - C43 with 31 satellites, according to Sivan, was scheduled to be launched. However, sources in ISRO indicate that the two launches were highly unlikely as the processes involved in integration and launch of satellites were yet to be completed.
Of the launches, GSAT-29 is a communication satellite targeting Village Resource Centres to “bridge the digital divide”. The second launch scheduled for the month was PSLV-C43, which was to carry a hyper-spectral imaging satellite along with 30 other satellites. Following the launch of these satellites, ISRO was to launch GSAT-11 and GSAT-7A in November, followed by Emisat and GSAT-31 in December. In January 2019, the launches announced included Chandrayaan-2 aboard GSLV Mk-III, PSLV C-45, and RiSat-2B.
However, sources said that the launch of the two satellites in the remaining days of October was difficult, if not highly unlikely. “If ISRO pushes for the launches in October too, it will be difficult to pull off two launches in two weeks,” the source said.
When contacted, an ISRO official who did not wish to be quoted said that various tests required for the launch of satellites was completed and the dates for the launch would be finalised in a week. “Since satellite launch involves several critical steps to pull off, it is difficult to follow a set schedule. However, all efforts are being made to ensure that the satellites are launched on time,” the official added.
Ten years ago to the day, on October 22, 2008, India’s space agency, the Indian Space Research Organisation (ISRO), shot a rocket into space carrying a satellite, Chandrayaan. The spacecraft, which entered the moon’s orbit 17 days later, provided India a dose of pride— among its many tasks, it also landed the Indian tricolour on the lunar surface.
In the next one year, the Chandrayaan conducted many scientific experiments and significantly established the presence of water on the Moon before it went out of contact on August 29, 2009.
‘First time right’In the last ten years, ISRO has generated a respectable performance record. It has flown the PSLV (the rocket that carried the Chandrayaan) 31 more times, making a total of 42 flights of the rocket, of which only two – the 1st and the 39th were failures.
It has also flown the rocket GSLV, twelve times successfully, test-flown the bigger version of it, the GSLV Mark III, launched 237 satellites for foreigners, and sent a spacecraft, Mangalyaan, to Mars. It got the ‘first time right’ with the Mars mission and has received due praise.
A second lunar launch, Chandrayaan-2, after a year’s delay, is expected to happen in early January 2019. In future, there will be a Mangalyaan-2, and Prime Minister Modi has promised that ISRO will fly an Indian into space before 2022.
Ten years after a milestone lunar launch and exactly half a century in existence, India’s space has managed to develop a halo around itself, but the mists of admiration mask a few unflattering aspects.
Conflicted opinionsFor a 50-year-old, ISRO is still way behind other space faring nations in technology. Writing in Quora, an ISRO scientist, Heman Phinehas admits that the organisation is “25-30 years behind NASA and Russia”.
Some scoff at comparisons of ISRO with others. They note that ISRO’s purpose– to serve India’s here-and-now needs are different than other agencies’, which are space research and military might. However, others opine that the 50-year-old organisation should have developed capabilities to launch heavy communications to high altitudes (36,000 km). China launches 30-40 satellites every year; ISRO launches around 3-4. China has mastered the science of sending a man to the space; while India is still 5 years behind, even in its plans.ISRO is the only space agency that does not possess capabilities such as orbital docking (joining two spacecrafts in space) and orbital re-fuelling.
Some say it is due to thin budget. In the four years between 2015-16 and 2018-19, the entire allocation to India’s space programmes has been around ₹22,000 crore. However, there is another view.
“Funding has never been an issue,” said Dr MYS Prasad, a former Director at ISRO’s Sriharikota launch station. “After the mid-1990s, not one programme of ISRO has suffered for want of funds,” said Prasad, who, incidentally, as the ‘range director’ played a key part in Chandrayaan.
‘Vertical Integration’Prasad believes that a problem of ‘mindset’ could have slowed things down. He said that there are people who “due to their love for technology” believed that “except them nobody could do it”, which hampered outsourcing.
While the private sector has been making parts of rockets and satellites — Godrej makes the Vikas engines for rockets — it has been a jobbing partner. A ‘vertical integration’ has not taken place. In 2016, ISRO tied-up with a consortium of Alpha Design Technologies, Tata Advanced Systems and Bharat Electronics, for making and testing satellites, but there is still no vertical integration for rockets.
Koppillil Radhakrishnan, the Chairman of ISRO for five years till 2014, observed that “vertical integration is a process of learning”. The industry needs “numbers”, and now is the right time to outsource.
ISRO plans 16-18 launches a year and has no option but to outsource. Radhakrishnan said that “meeting the required numbers while taking the organisation to the next level of excellence” is the biggest challenge facing ISRO today. He believes that ISRO is on the cusp of acquiring heavy-launch capabilities, come ‘electric propulsion’, which will enable satellites to do with 2.5 tonnes less of fuel, bringing down the total mass.
Electric propulsion, semi-cryogenic engine, re-usable launch vehicles and a manned mission to space (Gaganyaan) are the next steps that ISRO will be taking into space, but some people, including Prasad, feel that these are just incremental steps.
“I feel there is no long-term programme, things are very ad-hoc,” says Prasad, who wishes to see a strategy for the next 15-20 years, and not “this mission, that mission”. For example, he would like ISRO to work on an Indian Space Station – the existing, four-country International Space Station will be decommissioned in 2028. Working on a space station will force ISRO to strive to higher level of excellence and will keep the organisation learning. “But I am not seeing any clear signals,” he says.
A function was organised on October 16, 2018 at Antariksh Bhavan, ISRO Headquarters, Bengaluru, for releasing three publications on Indian space Programme. Dr K Sivan, Chairman, ISRO, Dr K Radhakrishnan and Sri A S Kiran Kumar, former Chairmen, ISRO along with many senior officials were present on the occasion.
The first publication released was a book ‘’The Leapfroggers” by late Sri Ved Prakash Sandlas, who took over as the Project Director of India’s maiden satellite launch vehicle SLV-3 from Dr APJ Abdul Kalam. The book effectively portrays the philosophy propagated by the great visionary and the architect of the Indian space programme, Dr Vikram A Sarabhai, who firmly believed in the concept of leapfrogging to state-of-the art technology rather than step-by-step approach for speedy development. The book also reflects upon basic ISRO culture and the cherished values of the pioneers of ISRO.
‘Indo-Russian collaboration in space: A recap @ 2017” was the second book released. This book is compiled and edited by Dr P.V. Manoranjan Rao, who carries the credit of writing on various space topics, and more importantly, on the Indian space programme. This book recapitulates 54 years of Indo-Russian cooperation in space. Its nine chapters vividly discuss several Indo-Russian collaborative programmes, including the provision of a Minsk computer to Thumba Equatorial Rocket Launching Station as well as M-100 sounding rockets, free launch of the satellites Aryabhata and the Bhaskara, provision of cryogenic stages and Indo-Russian joint manned spaceflight in which Wing Commander Rakesh Sharma undertook spaceflight in a Soviet spacecraft in April 1984.
Besides these two books, a special edition of the “Journal of Aerospace Sciences and Technologies" dedicated to ISRO's Scramjet project, was also released. This publication is brought out by the Aeronautical Society of India. Following the successful conduct of the challenging SCRAMJET flight test experiment in August 2016 from Sriharikota, ISRO intended to disseminate theaccumulated knowledge to the researchers and facilitated this publication.
It is hoped that these three publications will further inspire our younger generation to pursue their career in aerospace domain with added interest and take our country to still greater heights in the domain of space.
A TEL mounted SSLV if possible , would help the military in times of conflict replace attrition losses or launch specialised nano/micro satellites in support of ongoing conflict as per requirements.
I believe India should persue it.
