ISRO's Big Launch, Succesfully Test a Monster Rocket and an Astronaut Capsule

Countdown Begins: India’s GSLV-Mark III to Launch Tomorrow at 9.30 a.m

India's space agency is all set for one of its most ambitious tests. The countdown has begun for the unique maiden flight of Indian Space Research Organisation or ISRO's heaviest rocket till date - the 630-tonne three-stage rocket Geo-Synchronous Satellite Launch Vehicle Mark III.

This experimental flight marks a quantum shift in the rocket technology that India has mastered. This new rocket is capable of doubling the capacity of payloads India can carry into space. The rocket can deposit up to four tonne class of communication satellites into space. ISRO hopes this will become the main stay rocket in the future, which later will be suitably equipped for ferrying Indian astronauts into space.

On this flight, the rocket will be tested on how it performs during its travel in the atmosphere. The rocket will have the first two stages as active rocket engines, while the third stage that consists of the cryogenic engine is a passive stage. The heavy-duty cryogenic engine necessary for this rocket is still under development by ISRO. A full-fledged launch of the rocket can be expected in a few years.

The GSLV Mk III is an altogether new design of a rocket by Indian engineers. Incidentally its first stage consists of twin solid-state rocket engines that carry as much as 200 tonnes of propellant each. ISRO Chairman K Radhakrishnan says "These are the world's third largest rocket boosters."

Once ISRO masters this rocket, there may not be any need for India to send its heavy-duty communications satellites to space using expensive foreign launchers. It can also hope to make a dent in the multimillion-dollar commercial launch market of the world.

Astronaut Programme

This flight is really a two-in-one mission being undertaking by ISRO. The main passenger in the rocket is an Indian-made crew module. This marks the beginning of what could be India's initiation into the ambitious human space flight programme. While this crew module will be unmanned but this small room-sized cupcake shaped satellite is indeed capable of carrying two or three Indian astronauts into space.

In this flight the crew module will be hoisted up to an altitude of about 127 kilometres above earth. The crew module is also powered by its own engine and will be navigated and made to re-enter the atmosphere at a massive velocity. It will then be slowed down using massive parachutes. Incidentally the parachutes being used are the largest ever to be deployed by India.

The crew module will then make a splash down near the Andaman Islands in the waters of the Bay of Bengal. In its flight several parameters will be tested on the crew module, crucially ISRO is very keen to understand how the crew module and it's outer lining made of special heat resistant tiles withstands the over four thousand degree centigrade temperature it experiences as it comes hurtling back to Earth.

ISRO has proposed that it can fly Indian Astronauts into space using Indian rocket from Indian soil within seven to eight years of getting a government nod for its astronaut programme. ISRO has sought funding of about Rs. 12,500 crores for its humans space flight endeavour. When this happens, India will become the fourth country in the world to have indigenous capability of sending humans into space; the only other countries that have the necessary technology for this complex mission include Russia, USA and China.

Earlier this year, NASA tested its most modern crew module called Orion. Now, within a few weeks ISRO is following up with its own version of a made-in-India crew module. The guiding principle it seems is, if NASA can, so can ISRO.

This big launch is a watershed moment for ISRO and a real trial by fire as it charts new frontiers in space exploration.

Isro to test-fire its heaviest
rocket, GSLV-Mk III, today


The Indian Space Research Organisation (Isro) will test-fly
its heaviest rocket GSLV-Mk III on Thursday at 9:30am from Sriharikota in Andhra Pradesh.

Live telecast by Doordarshan and webcast of the launch will be available from 9am onwards.

This comes less than three months after Isro successfully launched Mangalyaan – a spacecraft orbiting Mars –catapulting India to the elite league of nations who have
successfully sent missions to the red planet.

GSLV Mk III is conceived and designed to make India fully self reliant in launching heavier communication satellites of INSAT-4 class, which weigh 4500 to 5000 kg.

It would also enhance the capability of the country to be a competitive player in the multimillion dollar commercial launch market.

“It is an experimental mission of GSLV MkIII towards launching heavier satellites,’ Isro chairperson
K Radhakrishnan told HT.

It is designed to be a three stage vehicle, with 42.4 m tall with a lift off weight of 630 tonnes.

“This is a suborbital flight, carrying a crew module which will go up to a height of 120 km and then descend,” http://www.hindustantimes.com/india-news/isro-to-test-fire-heaviest-rocket-today/article1-1297733.aspx

India launches largest rocket and unmanned capsule


_79805362_gslv-mkiii-x-11.jpg




India has successfully launched its largest rocket and an unmanned capsule which could send astronauts into space.


The 630-tonne Geosynchronous Satellite Launch Vehicle (MK III) blasted off from Sriharikota in the southern state of Andhra Pradesh on Thursday morning.

The new rocket will be able to carry heavier satellites into space.

India has successfully launched lighter satellites in recent years, but has faced problems sending up heavier payloads.

K Radhakrishnan, chairman of the Indian Space and Research Organization (Isro), told reporters that the test flight mission had been a success.

"It is a very significant day in India's space history."

The new rocket is capable of carrying communication satellites weighing 4,000kg, reports say, meaning India will not have to reply on foreign launchers to do so.

The main passenger in the rocket was an Indian-made capsule capable of carrying two to three astronauts into space.

Isro said the human crew capsule has "safely splashed down into Bay of Bengal off Andaman and Nicobar Islands" and that the experiment was successful.

Correspondents say this is the beginning of what could be India's foray into the human space flight programme.

Isro has sought funding from the government to send its astronauts into space and become the fourth country in the world to do so.

India is emerging as a major player in the multi-billion dollar space market and has undertaken several missions.

In September, it successfully put a satellite into orbit around Mars, becoming the fourth nation or geo-bloc to do so.

India takes step towards manned space mission, tests crew



Taking its baby steps towards realising India's ambition to send humans into space, ISRO today successfully tested the atmospheric re-entry of a crew module after its heaviest launch vehicle GSLV Mk-III blasted off from here.

Exactly 5.4 minutes after lift off at 9.30 AM from the Second Launch Pad of Satish Dhawan Space Centre here, the module separated from the rocket at an altitude of 126 km and re-entered Earth's atmosphere (about 80 km from sea level).

It descended in a ballistic mode and splashed down into the Bay of Bengal, some 180 km from Indira Point, the southern tip of the Andaman and Nicobar Islands.

The LVM3-X flight with active S200 and L110 propulsion stages and a passive C25 stage with dummy engine, carried CARE (Crew Module Atmospheric Re-entry Experiment) as its payload.

Weighing over three tonnes, the 2.7-metre tall cup cake shaped crew module with a diameter of 3.1 metres, which features aluminium alloy internal structure with composite panels and ablative thermal protection systems, was made to safely drop down into the sea by specially-made parachutes from Agra-based DRDO lab Aerial Delivery Research and Development Establishment.

The experiment also witnessed the largest parachute in action ever made in the country. The main parachute, which helped the crew module touch the waters at around 7 metre/second speed, was 31 metres in diameter.

Soon after the successful test flight, a delighted ISRO Chairman K Radhakrishnan said, "This was a very significant day in the history of Indian space programme for the development of the advanced launch vehicle that could carry a 4-tonne class of communication satellite into orbit.
