India successfully launches PSLV

[Bull]

Wednesday, January 10, 2007 (Sriharikota):


The Indian space agency's workhorse rocket - the Polar Satellite Launch Vehicle was successfully launched on Wednesday morning.

The launch marks the country's first tentative steps towards a manned mission into space.

The success of today's launch on the coast of Bay of Bengal in Andhra Pradesh also makes a good case for ISRO to get the Rs 16,000 crore it requires for its proposed manned mission.

Today's launch is a test for India's usage of re-entry technology, the success of which will be known after two weeks when the capsule is expected to re-enter Earth.

The launch erases the memory of the failed larger rocket launch in the summer of 2006.


Congrats to the scientists at ISRO....

PSLV was acarrying 4 satelites.

The PSLV-C7 is carrying the 680 kg Indian remote sensing satellite CARTOSAT-2, the 550 kg Space Capsule Recovery Equipment (SRE-1), Indonesia's LAPAN-TUBSAT and Argentina's six kg nanosatellite and PEHUENSAT-1.

Now the crucial day would be the day it makes the rentry into earths atmosphere.

Great performance, I envy you guys!

• "Our boys have done extremely well," Mr Nair said and added that "next year our target is moon mission Chandrayan-1".
  
  
  
• Mr Nair said of the targeted 635 km high polar sun synchronous orbit, the satellites were placed at 637 km high orbit, in what was almost a “precision launch”.
  
  
  
• Space capsule Recovery Experiment (SRE-1) would have to be in orbit for a minimum of 10 days.
  
  
  
• ISRO's next mission would be launch of INSAT-4B, the almost four tonne heaviest communication satellite from Kourou, French Guyana in March-April and to launch the PSLV-C8 with the "Agile"satelite.
  
  
  
• Considering the setback of GSLV-FO2 last year, extra care was taken for the launch of PSLV-C7, Vehicle Director of the PSLV mission George Koshy said here on Wednesday.
  
  
  
• It will be at least a decade before an Indian sets his/her foot on the moon. Ruling out manned lunar mission in near future, ISRO Chairman G Madhavan Nair said “it is a long way to go.

After runaway success, a major technological task begins for ISRO

555-kg SRE stays in orbit for 11 days, it will be de-orbited and brought back to the earth in a sequential manner.

It is coated with thermal tiles to prevent it from burning up when it re-enters the earth's atmosphere. After it re-enters the atmosphere, about 5 km above the Bay of Bengal, three parachutes in the SRE will open up one after another. First, the pilot chute will pull out the drogue chute, which will deploy, and then the main chute will deploy. The main chute will slow down the descent of the SRE and it will ultimately splash down into the Bay of Bengal, about 140 km east of the Sriharikota island. A floatation system will keep it afloat. Dye markers will make it visible. The Coast Guard will recover it.


Cartosat-2, the satellite's images could be used in town and rural planning. With its one-metre resolution, at the cadastral level, the boundaries of each land area could be easily identified. It would also be useful in road and drainage alignment, and studying the passage of communication lines.

No pak-s is daring to enter this post and making fools out of themselve.One day or other they will contest that our space technology was duplicated from pakistan.Hats off! Indian scientists.

Whats your problem

Indian space launch a breakthrough
By Khalid Hasan

WASHINGTON: If India is able to have the satellite it launched this week come back to earth, it will have joined the United States, Russia, China, and the European Union to have mastered the technology necessary to recover a capsule and its cargo safely.

In another development, Israel plans to launch one of its spy satellites from India.

Story No. 66 Story No. 67 Story No. 68 Story No. 69 Story No. 70 Story No. 71 Story No. 72 Story No. 73 Story No. 74 Story No. 75 Story No. 76 Story No. 77 Story No. 78According to a report in the Christian Science Monitor on Thursday, India is considering setting up its own manned space flight and the present mission is an important first step in that direction. Wednesday’s Indian launch was a milestone in more than one respect. Not only did it carry the SRE-1 recoverable satellite, which will perform zero gravity experiments before plunging into the Bay of Bengal, but it also included three other satellites ? the largest and most complex payload ever deployed by an Indian rocket.

According to the report, India wants to put a man on the Moon by 2020. Meanwhile, South Korea is just establishing a space programme, and its recent selection of two astronauts to ride on a Russian rocket became a nationally televised event. But unlike some of its space-bound colleagues, the Indian government’s ambitions are relatively frugal. Its mission to the Moon will cost about $88 million, while America’s Lunar Reconnaissance Orbiter has been tagged at more than $700 million. India is hoping to parlay its increasing space expertise into more contracts for launches and backroom engineering. Already, one European satellite maker, EADS Astrium, is outsourcing work to India, and Israel has chosen to launch one of its spy satellites from India.

What is less clear is whether the Indian space programme’s new direction might also help feed a more robust Indian military.

The question every Indian in a defence forum will give his eye-teeth to have answered. How many spy-satellites does India have in orbit?

Satellites working well: ISRO

"Everything is normal" with the four satellites put into orbit by the Polar Satellite Launch Vehicle (PSLV-C7) on Wednesday and all are "working well," Indian Space Research Organisation (ISRO) officials said.

Cheers Guys!
Great job by ISRO.

Reusable vehicle to cut costs, attract business
SRIHARIKOTA: The reusable launch vehicle programme could attract more countries to launch their satellites from India as the costs are much cheaper here.

The hi-tech project, which will boost India into higher orbits, is taking shape at Vikram Sarabhai Space Centre. Unlike, conventional rockets such as PSLV and GSLV (Geo Synchrononous Satellite Launch Vehicle), which can be used only once, RLV on the other hand, as the name suggests, can be operated a number of times.

According to space scientists, RLV has a two-fold advantage. First, it is expected to reduce the launch cost substantially. Currently, to place a kilogram of payload in orbit, the cost is between $12,000 and $15,000.

Scientists estimate that once RLV becomes operational this figure will drop by $1,200 to $1,500. Second, it will allow Isro to place satellites in orbit more frequently. Tentatively, the first technology demonstrator flight of RLV is slated for 2008-09. More flights could increase Isro's commercial opportunities.

The programme is rapidly taking shape and the conceptual design and the auxiliary power system for RLV have started. Studies are also in progress relating to its semi-cryogenic engine. It will be a two-stage-to-orbit (TTSO) vehicle.
The design envisages the first stage of RLV being configured as a winged body system which will attain an altitude of 100 kms. At a particular point it will burn out, re-enter the earth's atmosphere and land horizontally on a runway like an aircraft.

Thereafter, the second stage of the vehicle after delivering the payload, will re-enter the atmosphere and recover using airbags either on land or sea. Called the Indian version of the space shuttle, Isro officials say that RLV will be superior to the shuttle because it will have a number of enhanced safety features.

The US was the first country to launch a RLV programme, the space shuttle, which had its maiden flight on April 12, 1981.

Though described as a technological marvel, it proved an economic disaster. There are at present four shuttles and they will be phased out by 2010.

Space capsule to splash into Bay on Jan 22

SRIHARIKOTA: The space capsule recovery experiment is tentatively slated to return to earth on January 22, 2007.

Vikram Sarabhai Space Centre director B N Suresh and project director, SRE, A Subramoniam, after the successful launch of PSLV on Wednesday, said the target touchdown zone is about 140 kms off Sriharikota in the Bay of Bengal. The Indian Navy and the Coast Guard will play a key role in the recovery operations.

After splashdown, SRE will be taken to the nearest port by ship, which could be Ennore and then brought by road to Sriharikota for analysis. Said Subramoniam, "I feel my job has started and I am looking forward to 22nd morning."

The SRE programme will help Isro in evaluating the reusable launch vehicle technology. Suresh said provisionally the next PSLV launch carrying an Italian satellite, Agile, is slated for lift off on March 28, 2007 from the Satish Dhawan Space Centre, Sriharikota.
