pressure fed

So technically they just need a better valve to make the throttle fine tunable..
I mean they are making the Vikas engine throttleable down to 60% ... and that is a turbopump driven engine .
Edit : Got my answer Ty

ISRO can do, can create new team on that. Just depend on budget ! nothing else.

If m sure , if ISRO get budget , will able to do it.

The moment gaganyan announced we made an estimate (per year)and deadlines for various intermediary steps to achieve it within deadline that govt announced. A full estimate was made to achieve that without affecting any current projects or launch service. It required a totally new team for hsf and seprate budget for just gaganyaan . None of it happened so we were proved right that it is most likely to miss deadline

 

[TopWatcher]

Then why we are not developing "continuously throttlable thruster" for CY3 (better take time), what if step by step again fails in CY3 ?

It was discussed after the first announcement on isro reddit by oshin

Just imagine how the Soviets managed to land Lukhod 1 in 70s and then managed to run it for a whopping 10 kilometers and all that was done using 3rd gen computers.

We are not in even Soviets, Americans or Europeans of 70s. We are a ruined country who just managed to jumpstart itself to industrialise into league of major powers in last 20-25 years. All we have done is very recent.
Unlike cold war era programs which were political and endless capital was spared into multiple failed missions for urgency, space exploration is not an urgent political race for India. It is about making it in a cost effective and sustainable so that it can be continued.

US manned landing on moon was a waste if it has lost capability to send even humans in space. That differentiates India and China from cold war.

A lot more is there than just budget. A minimum 10 years timeline is needed to select experiments, develop payload and qualifying spacecraft. I'm not even accounting if a new rocket will be required or additional data relay & communication satellites will be needed geocentric and Martian orbit before that.

Budget problem is notning as compared to technological demonstration.

Alteast we can start now , then in 10 years we going to be capable.

If we keep saying this require 10 years or 20 years. Better start at the earliast.

we have bypassed many in-house testing facility that should have been built in India for sustainable hsf program instead we going for allies help testing things there even if hsf achieveed making it sustainable will be challenged task china built all that in house

Better is putting all money on human spaceflight and moon missions. Space exploration is sustainable if moved with an appropriate long term policy for gains.

So have we achieved any strategic parity in space and eo sats against our adversaries do we have enough space asset to not to bother about them are all of mision have long life to sustain in future? It would just lead to burn out all our resources for a non strategic project while our forces know nil about application aspect these project they refused built a cader for scientific application of space assets isro is solely responsible for that

All these lithium and other minerals reserves are found after launch of hysis. china also was able to find rare earth through mastering hyperspectral imaging one of Chinese gaofen is world's most powerful hyperspectral satellites in world can find difference 1u in spectrum on AOI our range is 20u still we achieved something with now say what is important some PR stunt or strategic parity? Why would private organisation do this and why would our military do this in it's budget? Only isro is left

 

[Swesh]

Hyperspectral imaging either airborne or remote sensing is extensively used to detect rare earth minirel

He answered that question,read those tweets again

This time they are using more steps for CY-3

even Chinese took Russian help for Shenzhou-5...we will eventually indigenise everything... Chinese took entire training in Russia...while ours took only part of the training...

remember, earlier we planned to import entire ECLSS, now we are making it indigenously

We had Hyperspectral payload in 2008 itself,the CY-1 HyS payload

continuously throttlable thruster would be much better, as even minute change in distance can create issue.

Hope ISRO test it thoroughly. Every thing cant be cheap.

ISRO should develop continuously throttlable thruster for future missions.

They are doing it, that's what he said, not for CY-3 but for future missions

Experimental payload

Yaa, but it shows we started this long ago....anyway they are developing new HyS payload for future missions
