ISRO General News and Updates

[Vamsi]

MK3 will work for another decade for sure!! Especially when are yet to utilize of SCE200!!

it will be in service untill atleast 2040

 

[Vamsi]

Please provide news source of statement stating GSLV will be retired. And wil NGLV be ready by that time or is it merely called LVM3 or something like that?

GSLV-Mk2 will be retired not LVM-3

Then would it make sense to keep the GSLV Mk3 around until the NGLV is ready and proven?

LVM3 will not be retired even in 2050s and 60s.

It is the new workhorse for international launches now like PSLV became in 2000s. If contracts with Blue Origin and cooperation with US & EU goes along, LVM3 will completely replace Antares for international launches even if it doesn't supplant Soyuz also. There will be more & more LVM3 launches from India and abroad in near future.

I don't think so, if NGLV becomes operational, LVM-3 should retire, payload capacity of NGLV(in reusable mode) & LVM-3 is same i.e 5tons to GTO...thus there will be no scope for LVM-3, thus it should retire before 2040

ISRO will develop NGLV, if not LVM-3 cannot compete in space launch market, europe is coming with Ariane-Next, Rocketlab is coming with Neutron, & there are many upcoming murican companies, hence there is no other option for ISRO, other than to develop NGLV before 2035, this is what Dr.Somanath said in interview with GareebScientist

No rocket lives forever. By 2040s itself, India's space needs will change. NGLV will have higher payload, yet will be reusable making it far more ideal for launching human spaceflight missions, science missions or building space infra like Space Station or sensing payloads to Moon, Mars. We already struggle with sending payloads to Moon and Mars. With NGLV, this won't happen.

Technically, as a Nations space program matures. It will need heavier launchers as missions get more complex. Same happened with US, China. Same will be with us.

The lower stream like small SATS, micro sats and commercial payloads will be probably handled by the private space companies.

Overall IMO, LVM3 will be crucial for this decade and might support our needs for early 2030s. Beyond that, we will need reusable and true heavy lift rockets.

Yes, only 2 LVs of ISRO will remain operational after 2035, SSLV & NGLV.....PSLV class will be replaced by Private sector, there are already plans by Skyroot to develop a rocket in that class..

exactly, I was iterating the same thing. Dr Somnath, himself hinted that NGLV will eventually replace GSLV MK3 once it gets fully operations. Also since NGLV will be reusable, the high cost of GSLV wont make sense than!!

Is it possible to land same configuration as CY3 in to an near earth asteroid or one of the asteroid in the belt between mars and Jupiter

LVM3 will retire only after a cost effective option of equivalent or more capacity like big RLV or NGLV is operationalised with high scale production. By no means, any new launcher under development by ISRO currently will be able to compete with LVM3 in that regard until 2050s.

As far as use is concerned, 10T to 15T class vehicles will always have a bigger utility over smaller and larger vehicles.

According to Somnath while talking to Gareeb Scientist, NGLV development will not be that long. Atleast should not be more then 10 years. They are trying to minimise the time in 7-8 years. They are also taking help from industry from the beginning to plan ahead. NGLV in its expendable form could be able to carry a lot.

No way I see LVM3 last till 2050s.

Somanath has nowhere stated any fixed timeline/target for it. NGLV has a 100 tonnes methane engine which is nowhere to be in sight for a decade at least. Added it would require a modular rocket design (which can be modified into heavy and medium launchers) and then the reusability. None of these technologies which aren't in our hands won't magically appear & mature in 8-10 years.

So even if a single variant of NGLV (which anyway neither will be suitable for replacing LVM3) files in 7-8 years, that basic version of NGLV won't even reach the production levels of LVM3 till 2040s in most likely scenario which would have become the domestic and commercial workhorse of Indian and foreign space industries.

Even if first NGLV comes in 2030, maturing same rocket and building a complete NGLV family to phase out PSLV & LVM3 will take late 2030s minimum (optimistical though).


There is no logical or realistic way to believe LVM3 will be phased out for next 3 decades. The reason ISRO is upgrading it itself is sufficient that LVM3 will serve well past after arrival of NGLV itself.

You mean the SCE-200 upgrade?

He said it, watch Gareeb Scientist's video, he said if timeline is more than 10 years it's uneconomical, he also said that PDR of Methalox engine is completed....

Just understand this simple logic, LVM-3 cannot survive beyond 2035 because of upcoming competition from Europe's Ariane-Next (engine already tested), Rocketlab's Neutron and other cheaper LVs

Well, it's nearly impossible to create a brand new rocket family in place of existing workhorse within a decade (unless its a cold war style space race).

Same stands for proposed timeline Ariane-next arriving in next decade to replace ongoing Ariane-6 then.

It is even just theoretical at entire for rocketlab which hasn't built a normal medium launch vehicle till date and Neutron is limited to drawing boards (just as Razor Crest of EtherealX whose finance itself is a question). Neutron is mere a concept as far as technological experience and financial abilities of rocketlab is concerned.

With Ariane-6 yet to fly, both Ariane-next and NGLV still on drawing board and no-one else coming even anywhere near them, its too unlikely that any space agency except SpaceX will not be using expendable rockets in 2040s and upto 2050s.

Anyone can give any statement about any timeline. We know what happens to timelines in R&D.

You are partially wrong about Ariane-Next, their Prometheus engine which was meant for Ariane-Next was already tested, their next step is VTVL technology demonstrator, Ariane-Next is definitely NOT on paper,active work is going on in that front

Just because Rocketlab only launched a small rocket, that doesn't mean they can't build Neutron, they will recieve all required technical assistance & as well as financial support from US govt to develop the engine as well as the LV,so it cannot be underestimated....

As far as the NGLV is concerned, watch ISRO chief's interview with GS, he clearly mentioned the it won't take beyond 10 years to develop NGLV.....from his words, Dr. Somanath is pretty much confident about both NGLV & Methalox engine....note that PDR of the engine is completed & detailed design work is going on.....he also said that SCE-200 will be shortlived

We both are going to live well past 2030 to see the production scales of Ariane-6, Ariane-next, NGLV and NASA' support for RocketLab (for a reason we don't know). So I'm resting my further arguments here.

It still anyway will need tremendous amount of money and tandem miracles (as one milestone is too little) to actually get rid of expendable launchers in 2040s.

CY-2 orbiter also carried same L&S band SAR payload similar to that of NISAR's payload although smaller one
