GSLV MKIII Vs. Atlas V 501

[axisofevil]

so the common core booster of the Atlas V is more efficent than using those heavy solid rocket boosters??

wonder why India hasn't tried to get the RD-180 from russia?

The US up until the 21 century did everything they could to slow down India in every sphere. The US threatened to bring Russia under sanctions with the Semi Cyrogenic engine tech collaboration with India. Luckily, Russia held up its obligation of supplying India with 10-15 engines. The collaboration ended though. So from then on, India was working on it.


The reality is many powers, from West to East will do anything to slow down India. Its better now but the situation was quite different back then. India must remain vigliant. The killing of Homi Bhabba was not an accident. I am quite sure our disintguished scientists have been targetted in the past to slow down advances in key programs. That's the name of the game.


It really disgusts me when I see America supporting Pakistan 24-7. Haven't you guys learnt your lesson after Osama was discovered living there under their protection?

I was comparing rocket systems via Comparison of orbital launch systems - Wikipedia, the free encyclopedia and I noticed GSLV MK III and Atlas V 501 performance is roughly the same but, GSLV MKIII weights 304 tonnes more. why is that? is GLSV a inefficient design

Victim mentality is why India is a poophole.

 

[Optimos Prime IA]

GSLV is smaller but more or less same capacity

Victim mentality is why India is a poophole.

What a moron . He is right . US and the west did everything to stop advancement of Indian space agency . Thanks to Russians .We over came that all .Soon over take many of the western space agency . Jealous mindset is the reason why West entered into shithole economy

I'm not concerned by victim mentality. The bigger concern for me is learning from our mistakes, our humiliations, our failures......then gaining constructive criticism and feedback....and making sure it never happens again.


The mentality you speak is a symptom of Inda that was constantly pushed by the previous govts under Congress. Unlike MK Gandhi, I believe in the quote "an eye for an eye." If the whole world goes blind, then so be it.

GSLV Mk III
Mass 640,000KG
LEO 8,000KG
GTO 4,000KG

Atlas V 501
Mass 337,000KG
LEO 8,250KG
GTO 3,970

the math just doesn't add up.

It's a quantum leap of India in space technology. I think the difference in weight is MAY BE due to sophistication in western technology and simplicity in eastern technology that's usually a core part of 2 from the beginning of the techno era and MAY BE that would be the reason for cheap launches from East and add up of cheap labour in it in South Asia may cut down cost even more.
This opinion is with A Big "MAY BE" and nothing but my opinion.

Wrong comparison gslv mk3 is more compared to titan 3c
Titan IIIC - Wikipedia, the free encyclopedia
not only that but also in weight and config .....

GSLV Mk III
Mass 640,000KG
LEO 8,000KG
GTO 4,000KG

Titan 3c
Mass 626,190 kg
Payload to LEO 13,100kg
Payload to GTO 3,000 kg

both of them uses heavy SRBs..................

The solid boosters were ignited on the ground and were designated "stage 0". Each booster composed of five segments and was 10 ft (3.0 m) in diameter, 85 ft (26 m) long, and weighed nearly 500,000 lb (230,000 kg). vs Propellant mass: 207,000 kg + material of booster

By the way give ISRO NASA budget then people will ask NASA who

NASA has 18 billion $ budget. India cant provide that amount of money to ISRO when currently ISRO's budget is just a bit over 1 billion $

India is moving man 10 years ISRO will have 10 billion budget

@C130 @Transhumanist @Abingdonboy

Thats because of technical advances and efficiency of fuel, specially Russian engines on Atlas.

But did you guys noticed one thing??



Atlas V cost: $ 164 million

GSLV mk III cost: $ 30 million


While they both do the same job. But I will say there are ways to work more on GSLV. It was designed 15 years back, now time to go to drawing board.

Not possible 2-3 billion $ is possible. no more than that.

 

[posedion]

Come 2020 Indian military space program requirements will be at 2 to 3 billion.....

 

[C130]

Self-reliance most likely. India's boosters might not be up to the RD-180 yet, but if they keep progressing like they have been, and keep developing newer engine tech, they will be.

I'm sure they could get the RD-180 from Russia, Russia needs business and India is a reliable partner, but India is keen on developing its own industries and achieving self-reliance in space exploration.

I commend this.

slow going process. seems more successful than HAL

ULA overcharges because it mostly deals with government contracts.


Falcon 9 costs $60 million and it's performance is about the same as Atlas V
