From ISRO's website:

"Indian Space Research Organisation successfully conducted the flight testing of its new generation high
performance sounding rocket today (March 3, 2010) at 08.30 Hrs, from the Satish Dhawan Space Centre (SDSC), SHAR.

Advanced Technology Vehicle (ATV-D01), weighing 3 tonnes at lift-off is the heaviest sounding rocket ever developed by ISRO. It carried a passive scramjet engine combustor module as a test bed for demonstration of Air- Breathing propulsion technology.

During the flight, the vehicle successfully dwelled for 7 seconds in the desired conditions of Mach number (6 + 0.5) and dynamic pressure (80 + 35 kPa). These conditions are required for a stable ignition of active scramjet engine combustor module planned in the next flight of ATV.

The successful flight testing of ATV-D01 is a step ahead towards the advanced technology initiative taken up by ISRO in the area of Air- Breathing propulsion."

Advanced Technology Vehicle successfully flight-tested

The Indian Space Research Organisation (ISRO) on Wednesday successfully flight-tested its new-generation, high-performance sounding rocket at the spaceport in Sriharikota, near here.

The Advanced Technology Vehicle (ATV- D01), weighing three tonnes at lift-off, is the heaviest sounding rocket developed by the ISRO. It carries a passive scramjet (supersonic combustion ramjet) engine combustor module as a test-bed for a demonstration of the air-breathing propulsion technology. An ISRO release said the rocket successfully flew at a velocity of more than Mach 6 (six times the speed of sound) for seven seconds. These conditions were required for a stable ignition of active scramjet engine combustor module planned in the next ATV flight.

“The successful flight-testing is a step ahead towards the advanced technology initiative from the ISRO in the area of air-breathing propulsion,” the release said.

The air-breathing rocket systems used the atmospheric oxygen from their surroundings and burned it with the on-board fuel to produce the forward thrust. This was in contrast to the conventional chemical rocket systems, which carried both oxygen and fuel on board, a rocket technologist said.

The air-breathing rockets, therefore, are much lighter and more efficient than the conventional rockets, leading to reduction in the cost of space transportation. That is, the cost incurred to put a satellite in orbit will be much lower.

The development of scramjet engine was complex and it involved a number of technological challenges. They included mixing of very high speed air (velocity around 1.5 km a second) with fuel, achieving stable ignition and holding the flame in addition to ensure efficient combustion within the length of the combustor, the rocket technologist said.

'Discovery of water on moon accidental'
Bangalore, Mar 3, DHNS:

Former Indian Space Research Organisation (ISRO) chairman G Madhavan Nair revealed on Wednesday that the discovery of water on the moon by Chandrayaan I was an accident.

Nair said that the purpose of the mission was not to detect water but a mineral detector aboard the moon vehicle by chance discovered the presence of the substance.

Delivering a lecture on ‘National Science Day’ at the Bangalore University’s Jnana Bharathi campus to commemorate the discovery of the ‘Raman Effect’, Nair said that some of the greatest discoveries of science had been accidents. “Chandrayaan I was fitted with an instrument to detect the presence of minerals such as Calcium or Iron. But the instrument in the end detected the presence of water on the moon,” he said. He called the discovery of water on the moon as India’s greatest contribution to the space research and scientific community.

Nair also estimated that the total amount of water on the moon was in excess of one billion tonnes and the total ice on the moon was more than a million tonnes. He added that the possibilities of the discovery was endless and could even extend to the human species setting up colonies on the moon. Nair said that although India was a late entrant to space research and ISRO itself was operating on a “shoe-string” budget, the country was second to none in the field.

Madhavan Nair urged youngsters to take up research for the sheer joy of it and not be lured by the fat pay packets offered by multi-national giants. “Most of the scientists who worked on Chandrayaan I were on normal government salaries. But their commitment and love for research is what made the mission successful,” he said. Also present at the event was well-known wildlife and biodiversity conversation scientist, Dr K Ullas Karanth, who said that a scientific approach to conservation and holisitic understanding of the effects of rampant destruction of nature was the need of the hour.

Presence of water in Moon path-breaking discovery: Nair

Fri, Mar 5 12:02 PM
Kochi, Mar 5 (PTI) Describing the recent discovery of thick ice deposits on the Moon as path-breaking, former ISRO chairman G Madhavan Nair said it opens up a vast avenue for human exploration. "This is the first time NASA and ISRO have confirmed the availability of water on moon.

Huge ice sheets were found in the polar regions of the moon. This is a path-breaking finding as it was earlier believed there was a vacuum in the moon," Nair, during whose tenure unmanned lunar mission Chandrayaan I was launched, said.

"The presence of water gives many ideas.Water can be split with sunlight to get oxygen and hydrogen.

While oxygen can be used by human explorers, hydrogen can be used as fuel either to generate electricity or use as rocket fuel for the return journey or even attempt a Mars mission from the Moon," he said. This also reduces the need to carry expensive oxygen and fuel payloads by future space missions, he said, addressing the Fedbank Hormis Memorial Foundation lecture on ''Technological Challenges for National Development'' here last night.

The cost of access to moon works out to about 50000 USD a kg and to go round the earth it is 20,000 USD a kg. Recently, the US had to cancel lunar exploration programmes due to the high cost, he said.

Nair said scientists have to evolve new technologies to reduce access to space by making less expensive rocket systems and to use re-useable rocket systems.A host of new systems and materials need to be developed, he said, adding by 2020, the aim was to reduce the cost of launch by half by adopting newer technologies.

ISRO conducts static test of liquid core stage of GSLV-MkIII | NetIndian | India News | Latest News from India | Breaking News from India | Latest Headlines

The Indian Space Research Organisation (ISRO) today said it had conducted the static test of its liquid core stage (L110) of the GSLV Mk III launch vehicle for 150 seconds.

The test was conducted at its Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri at 1600 hours yesterday, a press release from ISRO said.

While the test was originally targeted for 200 seconds, it was stopped at 150 seconds since a deviation in one of the parameters was observed. About 500 important parameters were monitored during the static test.

The next static test for 200 seconds will be conducted after analysis of this data, the release said.

The GSLV Mk III launch vehicle is being developed for launching the 4 tonne class of satellites in Geosynchronous Transfer Orbit (GTO). Measuring 17 metres in length and 4 metres in diameter, L110 is an earth storable liquid propellant stage with a propellant loading of 110 tonnes. L110 stage uses two high-pressure Vikas engines in a clustered configuration and draws its heritage from the second stage of PSLV and GSLV and strap-ons of GSLV.

According to the release, while in PSLV and GSLV, the liquid stage with single engine configuration burns for 150 seconds, the GSLV-MkIII requires burning for 200 seconds in a twin engine configuration.

First its personal attack.

2nd The 50cents are paid to glorify Chinese image but you are saying they are paid to troll.

Think before you speak.


sir,

ur wrong, they (50 cent party) was created to glorify communist governments works and now they are recruited for trolling also.

If u don't believe me than read BBC news.

BBC NEWS | Asia-Pacific | China's internet 'spin doctors'

Now, what will u say?

so next time before giving advise to others do some home work.

thanks
