ISRO aims at 45 to 50 launches | ISRO
The 12th five-year plan period will be a busy one for ISROs Sriharikota spaceport. If things pan out as ISRO hopes it would, then 2012-2017 will see more number of missions compared to previous five-year plan periods. ISRO chairman K Radhakrishnan, addressing the national conference on Space Transportation Systems: Opportunities and Challenges, organised by the VSSC and Indian National Academy of Engineering at Thumba on Saturday, said that the ISRO was targeting 45 to 50 launches during the 12th five-year plan.
In the 11th, the target had been 30, with six missions per year. The 10th five- year plan had witnessed 20 missions. (The Sathish Dhawan Space Centre, Sriharikota, has at present two launch pads. ISRO is planning a third one which will be able to accommodate advanced launch vehicles).
No Flaw in GSLV Design: Radhakrishnan said that the GSLV, which had two crashes in 2010, had no flaw in design. There have been problems in implementation which are being corrected. The next GSLV launch will be in the second quarter of 2012, he said.
In March 2012, the ISRO will launch a microwave remote sensing satellite which will be useful for the farm sector as well as disaster management. Cloud cover will not be a problem for this satellite, which gives it an edge over conventional satellites. The ISRO chairman said the years ahead would be a busy one for ISRO. At present, 170 transponders are in service, but the current requirement is 500.
The three-day conference, which focuses on low-cost space transportation, is being attended by a large number of scientists from India and foreign space agencies such as NASA, ESA and JAXA. It will conclude on Sunday.

ok this is a bit old news but i dont think it had been posted here.

Indian eye in space developed .

NEW DELHI, Feb. 16 (UPI) -- Bent on boosting its military intelligence, India is set to develop a new, cutting-edge surveillance satellite.
The spy craft, called the Communication Centric Intelligence Satellite is expected to be launched into orbit in 2014, keeping a close watch on hot spots in the troubled neighborhood.
CCI-Sat is part of a high-priority plan to develop electronic warfare systems for India's army, navy and air force, G Boopathy, director of the Defense Electronic Research Laboratory, was quoted telling local media.
The laboratory is developing the $25 million satellite and Boopathy said the project was still in its initial phases of planning.
"The focus now, is space; we have to equip ourselves for electronic warfare from space, too," he said.
Beyond surveillance, CCI-Sat is capable of picking up images, even conversations, between satellite phones.
The satellite is expected to orbit Earth at an altitude of 300 miles and keep watch on hostile regions in India's region by passing on surveillance data to intelligence command-and-control centers.
The Hindu newspaper reported the satellite will be fitted with electronic sensors that are more powerful than the Indian Space Research Organization's remote-sensing satellites.
It said the electronic warfare sensor would be "located on on the mountain range facing Pakistan, China, Nepal and the northeast part of the country, to detect troop or vehicular movement across the borders."
Only a select number of countries, including the United States, France and China, are using such electronic spy satellites.
While the payload will be built by India's Defense Electronic Research Laboratory, the satellite's design and development will be made by the country's space research organization.
India is poised to put an other two military Cartosat-2B satellites in orbit in the coming months. Both will also be used for military purposes.
Last year, India launched its generic RISAT-2 military satellite, which is keeping a high-resolution eye on the country's borders and coastline to watch for terrorist infiltration, Defense News reported.
Meantime, the director of Defense Avionics Research Establishment revealed that new electronic warfare technology has been developed for light aircraft and that the system was set to be tested imminently.
Defense scientists told local media that India was focusing research on technologies to intercept and jam satellite phone networks.
"That project is going on," an unnamed official was quoted as saying. "Within a year, it will be ready."
Among other developments, officials said a "penetration aid," that allows Indian military aircraft to penetrate enemy territory without being identified by surrounding radar.

The 11th 5 year-plan(3.2007~3.2012) of Indian,there are 30~36 missions in the schedule. By now, 13 missions had been implemented, among them, all 10 PSLV missions succeed, and all 3 GSLV missions fail. success rate 77%
There is one mission remain in the timetable--a PSLV mission in march 2012.
The task fulfillment rate<50%.
Now,The new great such plans have been pushed out again, Does India really only care about the "PLAN", instead of practise?
If a PLAN and its drawing up without any seriousness, it is better call it "conjecture". Such as:The 12th 5year conjecture,I think.
First of all there have been two gslv tests not three , second, why are u sticking ur *** in this? It's none of your business, it's norm to plan and then execute the plan.It have been really good if u just shut ur mouth and get some real facts...what a loser

Hey, take it easy winer guy. The forum is a place that is used for discussing and debating. But don't fouling our forum.
The GLSV missions during the Indian 11th 5-year "plan" (2007~2011):
1, 2/9/2007 INSAT-4CR 2,160 kg, Partial failure,apogee lower and inclination higher than expected, the sat was shortened its life.
2, 15/4/2010 GSAT-4 2,220 kg Failure, Failed to reach orbit.
3, 25/11/2010 GSAT-5P 2,130 kg Failure, destroyed after loss of control of boosters.
You can refute mine sanely with your reasons or theoris, such as the partial failure equal to the success, or the year 2007 is not belong to the 11th 5-year plan. But even so, the fulfillment rate of the " normal plan" is still <50%.

The new space race: China and India sign up to create world's biggest telescope
100-foot-wide optical telescope is nine times bigger than ones in use today
Will pick out objects 13 billion light years away
Sharp enough to pick out planets orbiting distant suns

China and India are catapulting to the forefront of astronomy research with their decision to join as partners in a Hawaii telescope that will be the world’s largest when it’s built later this decade.
China and India will pay a share of the construction cost - expected to top $1 billion - for the Thirty Meter Telescope at the summit of Mauna Kea volcano. They will also have a share of the observation time. It’s the first advanced telescope in which either nation has been a partner.
China and India have signed on to be partners for a project to build the Thirty Meter Telescope, which will be the world's largest when it's finished in 2018, at the summit of Mauna Kea volcano in Hawaii
China and India have signed on to be partners for a project to build the Thirty Meter Telescope, which will be the world's largest when it's finished in 2018, at the summit of Mauna Kea volcano in Hawaii
‘This will represent a quantum leap for the Chinese community,’ Shude Mao, professor of astrophysics at National Astronomical Observatories of China, said.
The Thirty Meter Telescope’s segmented primary mirror, which will be nearly 100 feet long, will give it nine times the light-collecting area of the largest optical telescopes in use today.
Its images will also be three times sharper.
The telescope, known as TMT, will be able to observe planets that orbit stars other than the sun and enable astronomers to watch new planets and stars being formed. It should also help scientists see some 13 billion light years away for a glimpse into the early years of the universe.
The TMT observatory will be so powerful it will allow scientists to see some 13 billion light years away and get a glimpse into the early years of the universe

‘Many things are manufactured in China, but we want to move up in terms of technology. We want to catch up as fast as we can. We also want to make contributions to world peace,' said Professor Shude Mao
China joined as an observer in 2009, followed by India the next year. Both are now partners, with representatives on the TMT board. Japan, which has its own large telescope at Mauna Kea, the 8.3-meter Subaru, is also a partner.
TMT may not hold the title of world’s largest for long, however, as a partnership of European countries plans to build the European Extremely Large Telescope, which would have a 42-meter, or 138-foot, mirror.
Mao said Chinese astronomers would likely want to use TMT to study the origin of planets outside our solar system, black holes, dark matter and dark energy.
China has leading theoretical astrophysicists, but it lags in the field of observational astronomy, Mao said. The telescope will help China overcome that.
‘China is ambitious in terms of its science goals. Really it wants to catch up as fast as we can,’ he said.
Mao said the project will also be valuable for the image China broadcasts to the world.
‘There are many things that are manufactured in China, but we want to move up in terms of technology,’ he said. ‘We also want to make contributions to world peace. TMT offers a great opportunity to do this.’
All astronomers, wherever they are from, look at the same sky, he said.

I don`t know but IMO Partial failure means that you have gathered enough data from your current adventure that you would not repeat the same in next launch. Partial success, not total success, partial success, nearly success all means that your payload wasnot delivered exactly like the way you want it, but you had to maneuver it to the designated orbit and thereby decrease it`s life span in orbit.. But then this is my understandingwhat the hell is a partial failure?
just short of success, almost success, not total success, partial success, nearly success..??
, I could be wrong
ISRO studying technologies to help spaceflight programmes
NAGPUR: After the successful launch of the Space Capsule Recovery Experiment (SRE) the Indian Space Research Organisation (ISRO) is now studying the possibilities of developing technologies that could help it in the human spaceflight programme in future. The organization has already begun work in this direction through a synergy of institutes in the country as a part of the pre-project phase of the programme the plan for which was first announced by the then ISRO chairman Madhavan Nair in 2007.
Delivering a scientific talk on the 'pre-project phase' of human space flight by ISRO Unnikrishnan Nair from the Vikram Sarabhai Space Centre (VSSC), Thumba, Trivandrum said that ISRO was identifying both the existing technologies that need strengthening and completely new technologies that could be required for an indigenous programme. It is a huge work and would require efforts by different institutes across the country in different specialties as well as industry. The talk was organized by Indian Remote Sensing Society at the Regional Remote Sensing Centre (RRSSC).
These critical technologies include anything and everything that would be required for such a project right from developing a space suit, environmental control system, life support system, crew escape system, human rating of launch vehicle, enhancing reliability and safety equipment. s known the whole process consists of three parts- ascent, orbital and descent. Each part in fact has a subs-set of technologies including selection and training of the crew. It would also require technologies for food and waste management as well.
Though the human spaceflight programme is just in the pre-project phase a network of institutes are expected to be its part. The project likely to be taken up in phases could take 7-8 years after the project is announced. The technology development programme naturally will also be using the experiences and lessons from similar projects by USA, China and Russia.
The SRE experiment by India which sent a 600 kg space capsule recovery launched using the Polar satellite Launch Vehicle (PSLV) rocket and safe return to earth in 12 days demonstrated India's capability to develop heat resistant materials necessary for re-entry technology. The human spaceflight is expected to send an fully autonomous orbital vehicle, a manned mission.
Earlier the RRSC project in charge A K Joshi introduced Nair. Das proposed a vote of thanks.

Tarmak007 -- A bold blog on Indian defence: ISRO marshals its forces towards RISAT-1 launch | It will be a huge boost for disaster-management: Radhakrishnan
Bangalore: It's business hours as usual for the Indian Space Research Oragnisation (ISRO). The message amidst the mess, is to stay focused on immediate missions and not the madness orbiting them, thanks to the Devas-Antrix row. Warming up for a possible mid-March launch is PSLV-C19 carrying the Radar Imaging Satellite (RISAT-1).
Not cowed down by non-stop criticism and direct shelling by the scientific czars, ISRO Chairman K Radhakrishnan has made up his mind not to enter the boxing ring. “Our onus is on the next launch. So many critical technologies are being readied and I am moving forward in confidence. As I said earlier, only mission matters,” Radhakrishnan told Express.
“We are putting everything in place towards this launch. ISRO has a huge work culture that's inspiring. We have our peers to whom we look forward. They are our guiding lights. They advice us ahead of critical mission. All my team assemble in an auditorium to debate and question about various launch preparedness,” Radhakrishnan said.
According to him, the PSLV-C19 will be the 21st launch of PSLV and in this mission, the 'XL' version of PSLV with six strap-on motors (PSOM-XL) is used. “These strap-ons are larger than the ones used in PSLV 'standard' version. This will be the third launch of the 'XL' version of PSLV. The 44-metre tall PSLV-C19 will have a lift-off mass of about 320 tonnne and it will carry the RISAT-1 remote sensing satellite into orbit,” Radhakrishnan said, in the company of his two trusted lieutenants.
The home-grown remote sensing satellite is capable of taking day and night images of Earth even under hostile weather conditions. “It will be one launch to watch as the disaster-management capabilities of India will increase immensely. Outsmarting the cloud-cover to take images will be a significant achievement, only a few nations can boast of. We are delighted about the prospects of this launch,” Radhakrishnan said.
The microwave remote sensing RISAT-1 carries a C-band Synthetic Aperture Radar (SAR) payload, operating at 5.35 GHz in multi-polarization and multi-resolution mode (ScanSAR, Strip and Spot modes) to provide images with coarse, fine and high spatial resolutions respectively.
“The SAR, being an active radar sensor, operating in the microwave region of electromagnetic spectrum, has the unique capability of imaging in all weather conditions. The SAR payload is based on an active phased array technology using transmit/receive (TR) modules, which would provide necessary electronic agility for achieving the multi-mode capability, providing spatial resolutions of one m to 50 m, and a swath of 10 to 240 km catering to multiple applications,” said an aide along with Radhakrishnan, who preferred not to be quoted.
The satellite weighs around 1851 kg and has the power handling capacity of 4.8 kW. The RISAT-1 will be launched into a 476 km orbit. “After three-axis attitude acquisition, the orbit will be raised to 536 km with 25 days repetitivity with an added advantage of 12 days inner cycle for CRS (Coarse Resolution ScanSAR) mode,” he said.

Chandrayan-2 faces delay after Russian Mars probe failure
The failure of the Russian Mars mission last month will cause a delay in the construction of a Russian lander for India’s Chandrayan-2 mission to the Moon, said Russia’s top space official.
As a result, the launch of Chandrayan-2, planned for 2013, may have to be postponed by three years.
Academician Lev Zelyony, head of the Russian Space Research Institute, was quoted as saying that the Luna-Resource lander may not be ready till 2016.
“There were plans to launch the Luna-Glob and Luna-Resource missions in 2015,” the Russian scientist told RIA Novosti. “But the dates may have to be moved, as the technical solutions that were used with NPO Lavochkin’s Phobos-Grunt were also used in the lunar projects and they clearly need to be reviewed.”
The Phobos-Grunt spacecraft, launched in November to retrieve soil samples from the Martian moon Phobos, became stuck in Earth's orbit after its engines failed to fire and crashed back to Earth last month.
A Russian government commission set up to investigate the probe failure blamed it on a burst of heavy charged space radiation that caused the onboard computers to reboot and go into standby mode.
Academician Zelyony, who took part in the investigation, said the review will not affect scientific instruments of Luna-Resource and Luna-Glob, but only their control systems and the spacecraft.
While the Luna-Resource lander is to travel to the Moon aboard the Chandrayan-2 spacecraft and put an Indian rover on the lunar surface, the identical Luna-Globe will be an entirely Russian mission, which is to carry a boring system for taking Moon rock samples.
The failure of the Russian Mars mission last month will cause a delay in the construction of a Russian lander for India’s Chandrayan-2 mission to the Moon, said Russia’s top space official.

Academician Lev Zelyony, head of the Russian Space Research Institute, was quoted as saying that the Luna-Resource lander may not be ready till 2016.
“There were plans to launch the Luna-Glob and Luna-Resource missions in 2015,” the Russian scientist told RIA Novosti. “But the dates may have to be moved, as the technical solutions that were used with NPO Lavochkin’s Phobos-Grunt were also used in the lunar projects and they clearly need to be reviewed.”
The Phobos-Grunt spacecraft, launched in November to retrieve soil samples from the Martian moon Phobos, became stuck in Earth's orbit after its engines failed to fire and crashed back to Earth last month.
A Russian government commission set up to investigate the probe failure blamed it on a burst of heavy charged space radiation that caused the onboard computers to reboot and go into standby mode.
Academician Zelyony, who took part in the investigation, said the review will not affect scientific instruments of Luna-Resource and Luna-Glob, but only their control systems and the spacecraft.
While the Luna-Resource lander is to travel to the Moon aboard the Chandrayan-2 spacecraft and put an Indian rover on the lunar surface, the identical Luna-Globe will be an entirely Russian mission, which is to carry a boring system for taking Moon rock samples.
