ISRO outlines plans to send Indians into space

An unmanned crew module will be put in orbit around the earth by a modified Polar Satellite Launch (PSLV) in 2013 as a forerunner to the Indian Space Research Organisation (ISRO) sending two Indians into space, S. Ramakrishnan, Director, Liquid Propulsion Systems Centre, ISRO, said here on Monday.

India has plans to send two Indians into space in a low-earth orbit and they will stay in space for about a week before returning to the earth. A third launch pad, at a cost of Rs.1,000 crore, will be built at Sriharikota, where the rocket that will take the Indian astronauts into space will be assembled and launched.

Mr. Ramakrishnan told a press conference here, after the successful PSLV-C15 flight, that the module in which the Indian astronauts would go into space had already been designed. The life-support systems, the thermal-proofing on board the module and the crew escape system in case of an emergency had already been defined. “We are also planning a launch pad abort for the crew in case of an accident,” Mr. Ramakrishnan said.

ISRO Chairman K. Radhakrishnan explained that the ISRO needed a highly reliable vehicle to take humans into space. Such rockets were called human-rated vehicles. Certain crucial facilities such as a new launch pad for sending human beings into space had to be built at the spaceport in Sriharikota. Facilities to handle the astronauts when they returned to the earth also needed to be built here. In the first phase of India’s Human Spaceflight Programme, these critical technologies including the re-entry technology would be developed. In the second phase, a human rated vehicle would be developed. In the third phase, astronauts would be trained to go into space. Normally, it took three years to train an astronaut, Dr. Radhakrishnan said.

Narayanamoorthy N., Chief Executive, Human Spaceflight Programme, Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, said the most important technology to be developed was the crew escape system. In the programme’s first phase, the module that would take the crew into space and a PSLV with a modified first stage would be built. An unmanned module, it would be identical to the final module. A host of technologies including life-support systems aboard the module and avionics would be developed in India with the help of research laboratories and industries, Mr. Narayanamoorthy said.

The location for the third launch pad site had been decided upon, said M.C. Dathan, Director, Satish Dhawan Space Centre, Sriharikota. It would boast of a vehicle assembly building where not only the ISRO’s current but future vehicles would be stacked up.

R.R. Navalgund, Director, Space Applications Centre, Ahmedabad, said Cartosat-2B, launched on Monday from Sriharikota, could be used in a variety of ways, depending on the imagination of the user. The images taken by its panchromatic camera could be used for planning roads in villages, building harbours, preparing accurate maps, keeping a watch on encroachments, and for various infrastructural activities, said Dr. Navalgund.

(Cartosat-2B’s images will have a resolution of 0.8 metres. In other words, the satellite from a height of 637 km, can take pictures of objects on the earth, which are three-feet long. The images can be used for estimating the acreage and the yield of crops; for finding out various types of forests and how thick the vegetation is; for laying ring roads and digging new canals; keeping a watch on mangroves and coral formations, and estimating the amount of water available in reservoirs and big lakes).

Mr. P.S. Veeraraghavan, Director, VSSC, said a Geosynchronous Satellite Launch Vehicle (GSLV - F06) will lift off from Sriharikota by the end of September or the first week of October this year. The stacking of its stages would begin in the second launch pad from July 14 (Wednesday).

A PSLV-C16 rocket would put in orbit Resourcesat-2 by the middle of October. It would also put in orbit two other satellites. The stacking of the PSLV-C16’s four stages would begin in August at Sriharikota.

LCA's Naval version prepares to roll out

India's first indigenous Naval Light Combat Aircraft, the LCA (Navy) NP1 is scheduled to roll out from the Hindustan Aeronautics Limited (HAL) Aircraft Research and Design Centre (ARDC) design hangar on July 6.The Defence Ministry has said that the aircraft will be an important milestone for the prestigious Naval Program of Aeronautical Development Agency (ADA), Bangalore.The Chief of The Naval Staff Admiral Nirmal Verma would be the Chief Guest at the function.'Roll-Out' is a significant milestone when the aircraft is brought out of the build hangar, where the aircraft is actually assembled part by part, ready for the phase of systems integration tests leading to Ground runs, taxi trials and flight.Once the ground based tests are completed, the NP1 is expected to fly by the end of this year and the NP2 is likely to fly by the end of 2011.The aircraft, with state of the art technologies and punch, is designed to operate from the future Indigenous aircraft carriers the Navy…

Intercontinental ballistic missiles well within reach

Advanced Systems Laboratory (ASL) is the deceptively bland name that obscures from public view the Defence Research & Development  Organisation’s (DRDO’s) most glamorous laboratory. At the DRDO missile complex here in Hyderabad, ASL develops the ballistic missiles that, in the ultimate nuclear nightmare, will carry Indian nuclear weapons to targets — thousands of kilometres away. Foreign collaboration is seeping into many areas of R&D, but ASL’s technological domain — the realm of strategic ballistic missiles — is something that no country parts with, for love or for money. No foreigner would ever set foot in ASL.
But Business Standard has been allowed an exclusive visit. The erudite, soft-spoken director of ASL, Dr V G Sekharan, describes the technologies that were developed for the DRDO’s new, 5,000-kilometre range Agni-5 missile, which was tested flawlessly in April. He reveals nothing except restraint stood between India and an intercontinental ballistic missile (ICBM) that…

GSLV Mark III with crew module launched successfully

India successfully launched its biggest ever rocket on Thursday, including an unmanned capsule which could one day send astronauts into space, the latest accomplishment of its ramped-up space programme.
The rocket, designed to carry heavier communication and other satellites into higher orbit, blasted off from Sriharikota in Andhra Pradesh.
On Twitter, Prime Minister Narendra Modi hailed the test mission as "yet another triumph of (the) brilliance and hard work of our scientists."
"This was a very significant day in the history of (the) Indian space programme," Indian Space Research Organisation (ISRO) chairman KS Radhakrishnan said from mission control as fellow scientists clapped and cheered.
ISRO scientists have been riding high since an Indian spacecraft successfully reached Mars in September on a shoe-string budget, winning Asia's race to the Red Planet and sparking an outpouring of national pride.
Although India has successfully launched lighter satellit…
