ISRO developing next generation Launch Vehicles for heavy satellites

Indian Space Research Organisation scientists are now developing next generation hi-tech Launch Vehicles or  Rockets for heavy satellites. This project will cut the cost of launching satellites by more than half the present.

This year, we will see series of tests and research works on GSLV Mark III. GSLV Mark III is said to completed by 2010-2011. The present GSLV can put only 2.2 tonnes of payloads into space. But, Mark III can put upto 4 tonnes of payloads into space. This will help Antrix Corporation (ISRO’s commercial wing) to offer the cheapest space launches in the world.

Mr. K Radhakrishnan, Director of Vikram Sarabhai Space Centre, said that ISRO is going to test the solid booster, followed by liquid stage and cryogenic engine will be tested this year. He also said that they are planning to conduct a test flight by 2010 or 2011. Radhakrishnan said ISRO will be able to pack more transponders in one space flight. “This makes it a cost effective solution and will give us a niche in the world in launching four tonne satellites,” he said.

GSLV is also planning to apply Mark III for human space missions. But, as far as the mission in 2015 is concerned, normal GSLV will be used which will put 2 Indians into space. But, GSLV Mark III has the capacity to put 3 astronauts at the same mission.

  • India to prove space supremacy to the world, especially to China

     India launched its first unmanned moon mission on Wednesday following in the footsteps of rival China, as the emerging Asian power celebrated its space ambitions and scientific prowess.

    Chandrayaan-1 (Moon vehicle), a cuboid spacecraft built by the Indian Space Research Organisation (ISRO) blasted off from a southern Indian space centre shortly after dawn in a boost for the country’s ambitions to gain more global space business.

    “What we have started is a remarkable journey,” G. Madhavan Nair, chairman of ISRO, told reporters.

    The operation is ostensibly about mapping the moon, but the mission comes on the heels of China’s first space walk last month, when Chinese astronauts were feted as national heroes.

    India does not want to fall behind in an Asian race to space that could have technological and military implications. There is disquiet in the West that China has military ambitions in space, with developments like anti-satellite missiles.

    India’s national television channels broadcast the countdown to the launch live. Some scientists thumped their chests, hugged each other and clapped as the rocket shot up into space.

    Greeted with patriotism in the media, the launch appeared to have distracted India from an economic slowdown, collapsing stock prices and outbreaks of ethnic and religious violence.

    Perhaps remarkably in a nation where hundreds of millions of people live in poverty and millions of children are malnourished, the cost of the mission has scarcely been questioned.

    “Destination Moon … Historic Day For India” blazed one TV channel on its screen.

    Barring any technical failure, the spacecraft will reach the lunar orbit and spend two years scanning the moon for any evidence of water and precious metals.

    A gadget called the Moon Impactor Probe will detach and land on the moon to kick up some dust, while instruments in the craft analyse the particles, ISRO says.

    A principal objective is to look for Helium 3, an isotope which is very rare on earth but is sought to power nuclear fusion and could be a valuable source of energy in the future, some scientists believe.

    It is thought to be more plentiful on the moon, but still rare and very difficult to extract.

    India’s project cost $79 million, considerably less than the Chinese and Japanese probes in 2007 and ISRO says the moon mission will pave the way for India to claim a bigger chunk of the global space business.

    ISRO scientists visited temples to seek the blessings of Hindu gods before the launch, and afterwards some expressed relief that rain had held off until the rocket was in space.

    “The rain gods have been kind to us,” Madhavan said.

     

     

    FROM NUCLEAR POWER TO SPACE POWER

    For many proud Indians, the launch is another notch in the country’s global ambitions. India recently signed a civil nuclear deal with the United States, making it a de facto nuclear power.

    “I’m very proud,” said Sunil Tambe, a taxi driver in Mumbai. “It means India can do these big projects and I think it will also benefit us because there will be more information and we can learn new things.”

    In April, India sent 10 satellites into orbit from a single rocket, and ISRO says it is plans more launches before a proposed manned mission to space and then onto Mars in four years time.

    “With China forging ahead in the space field, India cannot afford to lag far behind,” wrote security analyst Ajey Lele in The Indian Express.

    ISRO is collaborating with a number of countries, including Israel on a project to carry an ultra-violet telescope in an Indian satellite within a year.

    It is also building a tropical weather satellite with France, collaborating with Japan to improve disaster management from space, and developing a heavy lift satellite launcher, which it hopes to use to launch heavier satellites by 2010.

    India has launched 10 remote sensing satellites since 1998, has several broadcast satellites in space to control 170 transponders and has also launched light-weight satellites for Belgium, Germany, Korea, Japan and France.

    First Leg, Very Perfect, What’s next?

    After a historic launch and a successful injection into the transfer orbit, India’s first unmanned moon mission Chandrayaan-1 is ready for the next big task.Chandrayaan-1 has to get into the orbit around the moon where it will revolve for two years before returning back to the earth.

    The moon spacecraft, was put into transfer orbit around the earth by the Polar Launch Vehicle PSLV-C11 after it blasted off from the Satish Dhawan Space Centre.

    The 1,380 kg Chandrayaan-1, carrying 11 payloads, was released into a Transfer Orbit 18.2 minutes after the PSLV-C11 blasted off.

    After a series of procedures over the next two weeks, the spacecraft would reach its desired Lunar orbit and placed at a height of 100 km from the Lunar surface, marking the operational phase of the mission which would put India in the elite lunar club.

    Earlier, at the end of the 49-hour countdown, the 44.4 meter tall four-stage PSLV-11 lifted off from the second launch pad into a cloudy sky.

    This is the 14th flight of ISRO’s workhorse PSLV, which had launched 29 satellites into a variety of orbits since 1993, and 13th successive one in a row.

    Chandrayaan-1 is carrying 11 payloads, five entirely designed and developed in India, three from European Space Agency, one from Bulgaria and two from US, which would explore the Moon over the next two years. 

    Indian Space Research Organisation Chairman G Madhavan Nair described the successful launch as a historic moment in India’s space programme.

    “The launch was perfect and precise. The satellite has been placed in the earth orbit. With this, we have completed the first leg of the mission and it will take 15 days to reach the lunar orbit,” Nair announced in the mission control centre.

    Chandrayaan’s future and Gallery

    Chandrayaan-1 is the first spacecraft mission of ISRO beyond Earth orbit. Chandrayaan-1 will be followed by Chandrayaan-2 which features a lander and a rover. India and Russia will jointly participate in this project. However, there may be a provision to accommodate payloads from other space agencies as happened in Chandrayaan-1. This apart, studies are being conducted by ISRO on sending unmanned spacecraft to planet Mars as well as to asteroids and comets. Through such programmes, ISRO intends to undertake the exploration of space besides its primary mission of developing and utilising space technology for the overall development of the country.
