GSLV F12

What is all this white stuff coming off the rocket?

 

[Indx TechStyle]

TBH all our launch vehicles especially GSLV MK2/3 are quite inefficient wrt to other foreign vehicles. We have a long way to go. SCE and LOX engine(under development) will hopefully make us more efficient!!

We are way behind in space tech and the gap is only widening thanks to all these private companies. Let’s see how the ISRO-Japan moon mission collaboration works out. I think we need to be at $6 trillion+ GDP (upper middle income) to be able to afford a big R&D budget for space and other strategic technology. Let’s see.

Not really, we actually begun at scale of PRC & Japan sometime in 90s and our cryo entry was only in 2010s. It's been only a short while since India has been major space player.
Budget will shoot up only as per requirement as technology advances.

Well, it's so disappointing that after making organising a goddamn sub-forum for Indian space program with thread on every prominent related topic, people only spam this thread which is supposed for general news only.

Discovery of giant exo-planet, led by an Indian scientist, Work carried out at Physical Research Laboratory, adjunct, independent unit of ISRO

Scientists Discover an extreme Massive Giant and Most Dense Exoplanet

www.isro.gov.in

May 26, 2023

A new Jupiter size exoplanet with highest density of ~14 g/cm3 known till this date, and mass 13 times that of Jupiter has been discovered by an international team of scientists led by Prof. Abhijit Chakraborty at the Exoplanet Research Group of the Physical Research Laboratory (PRL), Ahmedabad. The team includes scientists from India, Germany, Switzerland and the USA. The discovery of this massive exoplanet was made using the indigenously made PRL Advanced Radial-velocity Abu-sky Search spectrograph (PARAS) at the 1.2 m telescope of PRL at its Gurushikhar Observatory in Mt. Abu by measuring the mass of the planet precisely.

Yes then we did not grow like PRC and our space budget stagnated. Not to mention scam after scam by ANC did not help as the focus was elsewhere. We should have been at $5-6 trillion by now even at conservative growth levels. Nothing except poor administration and anti development policy by ANC put us here. Have to wait until R&D budget goes up significantly. I am waiting to see how India’s private players help accelerate ISRO’s ambitions. Let’s see.

Its seems ANC really doesnt want India to grow. They working on something else, which now people start feeling.

Nice interview of ISRO chairman S. Somanath, by India Today editor Raj Chengappa. Some good comments about Navic, Chandrayaan, Gaganyaan, Aditya and comparisons( odious or irrelevant) between ISRO and other countries space agencies.

No, it's vice versa. Our space budget was stagnated because our program was limited.
PRC was already there in 1990s where are today.

Space budget was insignificant not because of budget crunch but because there was no plan. And it won't outgrow NASA tomorrow suddenly if economy grows since R&D consumes time.

exactly even with our massive defense budget we return thousands of crores to ministry because simply don't have good enough military industrial capacity that our military demands!!

how efficient the crypt stage is !!

GSLV is the Frankenstein of space launch vehicles.

(RANT INCOMING)

Straping on 4 individual liquid boosters, each with its own plumbing and separate fuel & oxidizer tanks . Which hauls an empty steel 1st stage for approx 10 seconds(don't quote me on this, not too sure.)

All of this, is because ISRO wasn't able to cluster 4-5 engines and provide it with thrust vector or Vernier thruster, which would in turn given us a much simpler two-stage vehicle and eliminated any need for the single Vikas engined 2nd stage.

And let's not talk about the COMPLEX non-restartble staged combustion upper(vaccum) stage hydrolox engine (c.e7.5) which is near impossible to be properly tested on a test stand in ground settings. And took us 5 failed/partially launches over a decade to overcome.

MOst failures of GSLV were of MK1 which had russian CUS.

Ok, 3 failures with indigenous engine out of total 6. Out of which the most recent was just 2 year ago.

Its fine naa.. New Engine... failures are expected. Same happened with SLV, ASLV series too. Or for that matter Spacex too had fare share when they ventured into new area.

Naa, only 2 failures with Indigenous engine, D3 & F10 flights

Unnecessary rant

ISRO's original plan for GSLV is to have L220 core powered by 4 Vikas engines just like in Ariane-4, but they didn't had the test stand to test clustered engines.

Now why didn't they build test stand to test clustered engines?? Answer is, Nambi Narayanan sir did proposed to build one,but the then ISRO chief Satish Dhawan sir rejected his proposal.
