ISRO successfully tests propellants system of GSLV-M III

The Indian Space Research Organization (ISRO) successfully tested the propellant system of the body's soon-to-be launch mega vehicle, in the Tamil Nadu's Mahendragiri district on Thursday.

In a landmark experiment, a team of eminent scientists and experts from ISRO carried out the static testing of the liquid core stage of the Geosynchronous Satellite Launch Vehicle Mark III (GSLV-M III).

Lasting for 200 seconds, the test was deemed a 'success' by the ISRO chief K. Radhakrishnan.

Radhakrishnan said there was just one other test that was required to be undertaken before giving the green signal for the final launch of the satellite carrier into space.

"The GSLV-M III, has three propulsion elements that give power to the rocket. The first one is solid motor...solid means solid propellants used in the rocket motors. Two such rocket motors have been used. Then the second stage is the liquid stage that will be tested today, and the third stage is the cryogenic stage which we are developing," explained Radhakrishnan.

The ISRO is using indigenously developed Cryogenic Upper Stage (CUS) for the first time since the launch of the mega shuttle, GSLV-D3, in April this year.

"We are developing GSLV-M III vehicle to put heavier communications satellites, that is, satellites with mass of four tons into a geostationary transfer orbit," said Radhakrishnan.

The ISRO chief also informed that the indigenous complex cryogenic rocket technology was a remarkable scientific advancement and could revolutionize space vehicles in the future.

The GSLV-M III, which is currently under advanced stage of development, uses two solid strap-on boosters (S200), L110 liquid stage and a cryogenic upper stage C-25.

India to Build Stealth Destroyers

The Indian Government has sanctioned $6.5bn of funding to build four stealth destroyers for the navy under Project-15B, a senior Defence Ministry official has said.

The four new 6,800t destroyers will be built at the Indian Navy’s Mumbai Mazagon Docks with greater stealth, advanced sensors and weapon packages, according to defensenews.com.

The destroyers will be fitted with a 1,000km range nuclear-capable cruise missile and an extended-range surface-to-air missile system being developed by the Defence Research and Development Organisation with Israel.

Construction of the destroyers will begin only after the three stealth warships under Project 15-A are completed.

The navy currently has 140 vessels and ordered 39 additional warships and six conventional submarines worth over $10bn in July 2010.

ISRO to achieve yet another milestone

The Indian Space Research Organisation (ISRO) will achieve yet another significant milestone in its space programme when it conducts a full duration static test of Liquid Core Stage for ccccclaunch vehicle, being developed to put four tonne class satellites into orbit.

The crucial test would be conducted on September 8 at the Liquid Propulsion Systems Centre (LPSC) at Mahendragiri in Tamil Nadu.

Vikram Sarabhai Space Centre Director P S Veeraraghavan told UNI that the tests would be conducted for a full duration of 200 seconds. He said, earlier 200-second test had to be aborted after 150 seconds following a minor leak in the configuration of a particular unit. The leak was identified and the problem rectified.

BRAHMOS cruise missile test-fired from Orissa coast

India today test fired the 290-km range BRAHMOS cruise missile. This condusted at the Integrated Test Range (ITR) at Chandipur off Orissa coast as part of trials by the defence forces to fine-tune its capability.

India and Russia are jointly designing the BrahMos missile, which is capable of carrying conventional warheads up to 200-300 kg and has a range of 290 km, to be in line with the international regulations.

6000kmph missile to be built.

India will become the first country to have hypersonic missile with speed of over 6,000 km per hour. This will be jointly developed with Russia and the agreement for this will be signed during the visit of President Dmitry Medvedev to India. Currently the speed of the missiles is nearly half of the new missile proposed. The missiles is expected to be ready by 2015-16.
