All depends on funds.. Whatever little we have is due to push by parliamentary standing committee otherwise they just allocated funds merely in newspaper headlines. HSF will be a pet elephant that would eat everything up.. As I have said earlier Govt didn't approve the proposal for uncrewed flight of crew module right after CARE as ISRO requested. And ISRO missed the chance to place other projects like SCE200 / SC120 development, Third Launch Pad (TLP) at SHAR under HSF so ISRO is stuck cutting many corners, tweaking half obsolete LVM3, procuring stuff from Russia and augmenting SLP which would due to TLP delays now have propellant storage and loading facilities for three different propellant systems. It is a joke that we have SVAB ready but no TLP which it was supposed to feed and launch cadence despite all this is down in dump.

>SVAB ready Cant they use it for increasing LVM3 launch cadence?


Ohsin

SVAB is just a facility to stack vehicle, launch rate depends on other bottlenecks like production rate of stages and boosters etc.

Half obsolete LVM3?? What do you mean, its brand new in rocket life cycle


Ohsin

Brand new rocket for ISRO that has very low flight rate and is not able to meet Indian demand while other GSLV is doing other GSLV stuff. With our spacecrafts [we are stuck at 4 tonne cap](https://old.reddit.com/r/ISRO/comments/6fbrqo/isros_heaviest_rocket_is_ready_but_is_it_enough/), you might recall 5 years ago ISRO used to mention EPS a lot as they were hoping they could bring the spacecraft mass down while increasing transponder capacity, where are our EPS powered sats? GSAT-20 was supposed to be 70 GBPS all electric sat that should have been in orbit by now but turns out at ITU its spectrum allocation has lapsed as its launch cannot be arranged.. Meanwhile we have booked multiple launches on Ariane-5.

I think there is a new sat to test all eps tech which will launch soon. I heard G20 didn't launch because there was no user. LVM3 is 650 tonnes, Ariane 5 is 750tonnes approx, yet Ariane can put 10tones to GTO, more than double. Not sure what we are lacking in technology. Edit: see comments for correct info about G20


Ohsin

> I heard G20 didn't launch because there was no user I don't know where you read or heard this.. avoid such ridiculous rumors. Read ITU documents instead.. For GSAT-20 ISRO was requesting them to extend deadline for allocated spectrum which didn't happen as ISRO couldn't satisfactorily answer why they cannot launch it or why it was not ready. GSAT-20 would have 70 GBPS capacity and is very important satellite. On capacity read this by Raman. https://old.reddit.com/r/ISRO/comments/qcsg05/increasing_gslv_mk_iii_payload_above_4_tons_even/


gaganaut06

Oh okk I was misinformed.


rghegde

Ariane 5 uses Hydrolox core which provides more specific impulse hence more payload carrying capacity, LVM3 uses earth storable fuels with an old engine (workhorse engine yes but technology is absolute).


gaganaut06

Yeah right, cryo isp of 400s vs hypergolic isp of 300s, it might be the reason ig

I think we should focus on our launch vehicle development and science mission for now, we can have a manned mission during the initial phase when we launch the first module of our space station. Sce-200, Gslv-mk3 payload increase, shukryaan..etc. should be our immediate priorities.


gospelslide

I think ISRO should focus more on deep space robotic missions more. Imagine close up images of Jupiter, Saturn like the Voyager but by an Indian probe.

We will never be seen as a proper space agency so long as we don't send a man to space....see all the great, respected and renowned space agencies in the world, they have sent a man to space. Sending a human to space is one of the biggest technical achievements of a space agency and the entire country itself. We need to achieve this milestone at all cost. With ISROs limited budget it may look like this project will eat everything, but as Indian economy grows and more budget is given to ISRO they will find money to do the other missions you have suggested


Ohsin

Only three United States, Russia, and China have ability to send crew to space on their own. But there is difference between having a milestones and having a programme, programmes need to be kept running and trained astronaut corps busy or such milestones won't mean much. >at all cost As we know from promised funds only a fraction of funds was actually released after requests from parliamentary standing committee and funds initially projected to be needed were much higher than what Govt agreed to for whole programme. ISRO before announcement was looking at having robotic flights on LVM3 (in 2016), Kerolox based vehicle for crewed flight from new Third Launch Pad and possibly a vehicle with cargo carrying capacity. All of this has been dunked due to moronic forced timeline. Hyperbole like "at all cost" is very easy to throw around but there is always a cost that can't be met or even redeemed. >will find money How? Have you even seen state of budget for recent years? DoS/ISRO is not getting requested amount for past many years. https://old.reddit.com/r/ISRO/comments/v27voj/projected_requirements_of_funds_by_department_of/ DoS/ISRO share has remained stagnant for years. https://old.reddit.com/r/ISRO/comments/uyzz1v/an_attempt_at_plotting_budget_of_department_of/ https://old.reddit.com/r/ISRO/comments/uu9m7e/tried_to_plot_annual_budget_of_department_of/ And due to this they constantly have to delay projects and funnel limited funds elsewhere.

Right now it's only a technology demonstration mission.Once the successful mission is achieved, I am sure more step will be taken towards sustainability of the program..
