Comparison of Asian national space programs

[KRAIT]

1. The first flight of the India designed tested and produced small cryogenic rocket engine failed to properly start-up and ignite on April 15, 2010 setting back the ISRO intent to have its own cryogenic engine for the GSLV use. Defining the technical issues that prevented its engines ignition and their resolution are anticipated to take about a year before it will again be flight tested. Although ISRO is indicating it may be flight tested again before 2010 is over or early in 2011. In the mean time India has returned to using purchased Russian cryogenic engines to assure GSLV continued operations.

Seems like you are doing some research or PhD on Indian Space Program and its failures....

buddy please ur government screws up A LOT. u just dont know it because they keep it hidden

chinese rocket tragic accident - YouTube

The Chinese government never hided the launch failures，all the Chinese know we failed in 1996 and there were casualties but not the stupid lie "A village was destroyed and 1000 died" that only morons believe。
This video is made for the morons because morons trust everything they were told and they are not able to tell the difference between earthquake and fire

 

[kingkobra]

PSLV from Russia too

India originally tried to buy the technology to build a cryogenic upper stage from Russia, but under pressure from the United States, that technology was not provided. Therefore, ISRO has been working on developing a cryogenic upper stage for the past eleven years ( failed in 2010)

i feel so sorry to tell you the truth BIG MOUTH INDIANS

on the ground

only successfully tests in the space called successful

Big Mouth blowed up in the sky in 2010 do u remember?

GSLV GSAT-5P Launch failed & explodes in Mid Air on December 25 2010 - YouTube

Even if it launches a rocket successfully you are going to say that it because of help from russia
so it does not matter to me to prove anything to you

 

[RISING SUN]

wake up

SLV, ASLV, PSLV are all using Russian Engine. GSLV blowed up in 2010, GSLV III on the ground testing helped by Russian


ROFL Big Mouth Indians

Very first thing SLV, ASLV, PSLV didn't used or not using any Russian engine. These rockets used Vikas engine which are based on Viking series of European Rockets. It was France which helped India in developing these Rockets,not even Europe Space Agency. So get your doubts clear before vomiting crap theories. Russia did not provided help in SLV, ASLV, PSLV programs. It did helped in GSLV by providing cryogenic engine,even it didn't provided help in developing the engine itself. That should be enough for clearing your mind today.

Its vikas engine!!! The Vikas engine, based on the French Viking engine developed for Europe's Ariane launcher, is used in the Polar Satellite Launch Vehicle (PSLV) as well as the GSLV.
The ISRO has farmed out the manufacture of the engine to three Indian companies: Machine Tools Aids & Reconditioning of Hyderabad, Godrej and Kerala Hitech Industries Limited (Keltec) based in Thiruvananthapuram. The final assembly of the engines and the stages is, however, carried out by the ISRO. The PSLV requires only one Vikas engine (for its second stage). The GSLV, on the other hand, needs five such engines: one for each of the four strap-ons and one for the second stage. The second stage employs indigenously manufactured Vikas engine and carries 40 tonne of liquid propellant — Unsymmetrical Di-Methyl Hydrazine (UDMH) as fuel and Nitrogen tetroxide (N2O4) as oxidizer.
The Vikas Engine is a liquid fueled rocket engine made by India. It was developed by Nambi Narayanan and his team during the 1970s. It is similar to, the Viking.
The engine is used as the second stage of both the PSLV and the GSLV launch vehicles, with four strap-on boosters. The engine is also capable of swivelling.A up-graded version of the engine has a chamber pressure of 58.5 bar as compared to 52.5 bar in the older version.

Planned launches
C21 PSLV-CA August 2012[69] Sriharikota France SPOT-6 (France) Planned
C20 PSLV-CA October 2012 Sriharikota IndiaFrance SARAL Planned
An old news but never heard of it earlier.
Buoyed by its success in placing eight nanosatellites in prescribed orbits, the Indian Space Research Organisation (ISRO) is hoping to stage another feat by launching 100 nano-sats at one go. Scientists at the Vikram Sarabhai Space Centre, Thiruvananthapuram, are preparing elaborate drawings to make this event happen some two years from now.
The ISRO has already intimated universities world wide about the project and has extended an open invite to any varsity to take part in the historic venture. Within the country, the IITs in Kanpur and Mumbai were among the first to express interest along with ISRO’s Indian Institute of Space Science at Thiruvananthapuram. The Madurai Kamaraj University is already in the process of fabricating its satellite.

Can you tell me the name of that engine buddy used in SLV,ASLV,PSLV? Hmmmh that seems to be pretty much tough for you.

By the way PSLV has repeatedly proved its reliability and versatility by launching 53 satellites / spacecrafts ( 26 Indian and 27 Foreign Satellites) into a variety of orbits so far. More than indian ones. Way to go PSLV.

 

[Hello_10]

I have saw someone here talk about India petrol price higher 20%-30% than China... So why India's $1.32b has more purchasing power than China's?

a simple question and a simple answer as below:

GDP on 'exchange rate' terms; India-$1.6tn & China-$7.4tn

GDP on 'PPP' terms; India-$4.45tn and China-$11tn

this way, spending by India on space research on PPP = 1.32 * 4.45/1.6 = $3.7bn

and spending by China on Space Research on PPP = 1.3 * 11.0/7.4 = $1.93bn

we know that we cant have simple calculation without considering other aspects, specially of the imported products which a country import in US$, true. but we know that majority of expanses occur inside the country itself, by utilizing local workers/ products

Really amazing from a Singaporean. I didn't knew whether modern rockets uses petrol as a fuel or not. I am sure you are a false flagger. I guess Roll in deep is thinking that transportation cost of traveling by scientist & goods,materiel leads to $1.32b. Otherwise why to take name of petrol at all.
Just chill buddy why are you taking so much tension. Leave it to us.

Vikas engine is helped by Russia too. you first indigenous engine blowed up in 2010
First flight test of India's indigenous cryogenic engine fails | NetIndian

1st thing it's not Vikas engine which failed neither indigenous cryogenic engine.
And 1 more thing Vikas is used in 2nd stage while cryogenic engine is used in 3rd stage.
In 1st failed test of indigenous engine it failed to reach orbit due to malfunction of Fuel Booster Turbo Pump (FBTP),while in 2nd test it was destroyed by range safety officer after loss of control of liquid fuelled boosters.
So simple thing is that problem is in booster not in cryogenic engine. Cryogenic engine starts burning after 8.33 minutes which you can't see from TV camera easily let alone naked eye.
Any problem in understanding this simple thing.
I am here. Don't go away. Happy to help.

Holy lord at last you accepted at all that India is trying hard to develop its own indigenous cryogenic engine.
India sought(not buy option) help from Russia in it because it's not child game. & it's true that Russia didn't provided help because of international pressure which I have clearly stated in my earlier post.
So chill out man.

2010 BIG MOUTH BOMB!

Again same mistake. Holy ****!!!!!!
How much time I will have to say that Cryogenic engine starts after 18.83 minutes. I have made mistake earlier by saying it 8.83 or 6.83 minutes. It's exactly 18.83 seconds after launch when cryogenic engine turns on. What video is showing is fault in booster phase in the initial stage. So get clear your facts mate. Don't confuse others with crap & repeated material.
Jai Hind.

 

[RISING SUN]

Never heard of that...and even if it is true then taking help is better than copying stuff which is unethical...

You never heard because you bunked the class. I didn't so I didn't fell into the trap of laman12345. India developed Vikas engine indigenously by taking help of France which was a partner country in Viking Program. So Vikas is based on Viking not Russian engine as laman12345 is spreading rumor. Better focus on lecture.

9 out 10 ere nano satellites....stop comparing with China, they were 2 decades ahead, but we can catch up...so keep our head low and reach the pinnacle silently.

Wait few more time mate,India is going to launch 100 nano satellites in 1 go.
It's not so easy to integrate many satellites in 1 launcher. It's not like binding small things in a bamboo. It ask for tech maturity. It's easy to integrate 1 satellite & launch/separate it but hard to integrate many satellite & separate these satellites in diffrenet-2 ranges. If 1 satellite misses it can cause problem to others because they have to be in the sequence.
Jai Hind.

so what, it's just a satellite missed the orbit, but your India-Russian made rocket totally BLOWED up!!!!



India can't even produce it own "indigenous" rockey engine

india space program is totally a joke

I wasn't Ind-Russian which blew up. It was Indian indigenous one. Booster was faulty.
India had,has & will produce indigenous rocket engine.

I have saw someone here talk about India petrol price higher 20%-30% than China... So why India's $1.32b has more purchasing power than China's?

Actually oil prices are mostly the same throughout the world, but other factors like demand and supply, taxes and commision for the petrol pump owner cause difference in rates......
Since China's demand is much higher than what is supplied at any point of time, the government has to spend more money to import oil and thus cause comparitively and situationally high taxes......also with the rising income of the population in China, there is also a rise of petrol pump's commision , who want a larger part of the profit.................
Thus Petrol is more expensive in China than in India..........

But the difference in budget does not matter cause in India, most of the money goes to R & D, whereas in China ,since their program is already developed, they can spend far more on production.........
Once India reaches that stage of development you may see it's budget falling down China's........

1. PSLV is from France

India's engines are made or bought from other countries, so India is not a space power

No, Anyone of this forum know with a freefall Rupee India GDP only $1.4-1.5 trillion now.
If you use petrol price to compare the purchasing power of these two countries, India petrol price higher 30% than China mean it has less purchasing power than China.
India is $1.4 trillion and China will be $7.4T* (1+30%)=$9.62T.
