India launches another new satellites :PSLV rocket launches communications satellite


Sriharikota: Scientists at the Indian Space Research Organisation (ISRO) in Sriharikota have launched a new communications satellite using the smaller of their rockets, the Polar Satellite Launch Vehicle (PSLV).

The transponders on the satellite, G-SAT12, will be used for education, telephone and telemedicine services. It weighs 1410 kgs and costs 80 crores. India is short of transponders, and today's mission, if successful, could add 12 C-band transponders.

The PSLV, worth 90 crores, has established itself as a workhouse rocket - this is its 19th mission. It's considered complex and unique because it entails five special orbital manoeuvres. The PSLV has to ensure that the satellite is injected into the correct geo-synchronous orbit - that will take a few days.

Neither the satellite nor the rocket are insured.

Two more launches of the PSLV are expected later this year.

The PSLV is being used because the GSLV (Geosynchronous Satellite Launch Vehicle) is out of commission due to recent failures, including one in December which included a domestic communications satellite. Before that, the GSLV had failed in April 2010.

yes indeed its very sad when
millions of indians lives in shanti town and in mumbai???
pls built them some toilet so they dont have to go out for >>>>>>poty!!!!!!!!!!!!

more than 60% of your people does not have proper sanitation and under poverty. You people planning to launch rocket in the moon where 50% of your people dont know how to use toilet!!! I recommend you to get civilized first before playing around with nukes, plutonium and olympic main to toilets bhi band ho gaye theen.
bend your efforts to have good toilet technology for next olympics.....thats is moral of this story....Mushwara moft ha warna dunya phir hansa gi.
toilet band ha or rocket chand per.
indian Bhooka hain or bapo chand per.

the satellite is used for good purpose.
it will provide communication at cheap price to indian companies!

if we buy from open market it will cost us 2-3 times more !Its saves us foreign currency,employ our citizens and get the work done cheaply !!

Entire mission cost was 90 million $(90 crore for vehicle+200 crore for satellites) !!while pakistan will spend 300 million $ in building a satellite with chinese help and send them via chinese launch vehicle costing more than 300 million $ !!

Pakistan should be happy buying paint from usa(sorry banned paints ) and paint chinese and north korean missiles with pakistan flag :)

[just like a q khan got no dong missiles from korea in return of centrifuges supplied by pakistan]

still u need to build TOILETS???????????

we are bringing cheapest toilets which cost them 200 Rs !!
But in village ,people like to defecate in fields. India adds 20% growth in budget ,so in every 4.5 years;its budget doubles;so it wil have enough money to spend on all social you dont need to worry.we have enough concepts of sulabh sauchalaya which will cover all vilages,towns,cities in few years at cheap costs!!

pakistan cant or wont be able to compete with india in any fields !!india spends more money on health,education in % than pakistan does!!



ood news =>Indian communication satellite raised to near its orbit(36000 Km)

Satellite will function for 7 years!(it loses fuel of 5-6 years by raising orbit)
ISRO needs to produce the 4500 kg satellite carrier :GSLV cryogenic engines if it want to be in satellite launching business!!

With respect to launching 3000+kg satellites with heavy launch vehicle :India had suffered two successive failures with its indigenous cryogenic engines in 2010 !!european space agency charges 2-3 times more money to send a satellite ;hence there
is great need to excel in it if indians want to associate with manned/unmanned space mission in future

by the way remember the slain salmaan taseer tweet:

Why does India make fools of themselves messing in space technology (GSLV)? Stick 2 bollywood my advice

[h=1]Manned missions being discussed: ISRO chief[/h]
SRIHARIKOTA (ANDHRA PRADESH): India's space agency has plans to launch a manned space mission in the future, but a lot of work needs to be done before that to ensure such missions are failure-proof, a top scientist has said.
K. Radhakrishnan, chairman of ISRO, said here that the space agency will have to first master the rocket technology to launch heavy communications satellites before it can progress to a manned mission.
"Rockets that carry humans cannot have a failure rate of more than two per thousand flights," he said after the successful launch of latest communications satellite GSAT-12 from the space port.


"Further what we have now (Geosynchronous Satellite Launch Vehicle) is only an unmanned rocket where the reliability should be 99 percent," Radhakrishnan said.
"We are trying to understand the intricacies of manned space mission. ISRO has to work on areas like thermal protection, life support and crew escape systems."
"We had a long discussion on manned space mission. The initial plan was to put two humans in space for seven days," he added.
According to him the first mission is to build a reliable GSLV rocket for launching heavy satellites.
He said ISRO is expected to be ready with a GSLV rocket to be powered by its own cryogenic engine next year.
Queried about the second space capsule recovery experiment (SRE-2), P.S. Veeraraghavan the director at the Vikram Sarabhai Space Centre, said the capsule is in the final stages of integration and the mission will be sometime next year.
Meanwhile, ISRO will follow a multi pronged approach to augment its transponder capacity - automatic receivers and transmitters for communication and broadcast of signals, a top official said.
"We can lease transponders from other satellite operators and launch our own satellites. ISRO (Indian Space Research Organisation) currently has 175 transponders whereas the demand is for 200 more transponders," Radhakrishnan said.
He said ISRO will launch a three-tonne communication satellite GSAT-10 with 30 transponders using Ariane rocket.
"We need few satellites like that. Two of the existing communications satellites -- Insat 2E and Insat-3C -- are nearing their end," he added.
Queried about the efficacy of using the other rocket -Polar Satellite Launch Vehicle (PSLV) in launching communication satellites - like GSAT-12- he said: "GSLV rocket is better for such missions. When GSLV Mark III variant under development will be much more efficient."
Officials said after the two successive failures of GSLV rockets last year the space agency has understood the failure cause.
Speaking about satellite GSAT-12 launch, T.K. Alex, director of ISRO Satellite Centre, said the initial operations went off smoothly.
"The solar panels were deployed and are generating power. The satellite orbit will be raised from 22,020 km apogee (farthest point from the earth) to 36,000 km apogee tomorrow and day after. All the 12 transponders in the satellite will be tested by the end of this month," Alex said.
He said there will be sufficient fuel left in GSAT-12 after raising its orbit to 36,000 km apogee so that it can be in operation for seven years.
