@Indx TechStyle @Okabe Rintarou @Swesh and others

So with the stage change, will they call it LVM-4 or LVM-3 Mark 2?

Leaving few COMMUNICATION HTS every 3gen satellites falls into catagory of below 6 ton sat we can easily dich forigen launcher besides those communication sat if we manage to achieve that capacity

As GSLV-Mk3 goes commercial, work on semi-cryo picks up pace - Times of India

As the GSLV-Mk3 or LVM3 prepares for its second commercial launch, expected in early 2023, Isro’s efforts on enhancing its weight-lifting capacity is gaining pace with the space agency expected to complete qualification tests for the semi-cryogenic stage (SC120) in a couple of

6 ton info is recently added on page of vssc read it

But making it commercial viable will take time, at least 3 development flight required to commercialize new engine.

Woh toh hoga hi but good thing is they are starting it i never expected it to start soon after dumash destruction in Ukraine

I read somewhere 7.5 tonnes to GTO with SCE-200 and new tank.

Officialy it was always 6 ton to GTO

 

[Abdus Salem killed]

Is 6 tons to GTO enough for a modular space station?

It's LVM-3SC..... personally I would prefer LVM-3A...it would be simple

Except I-8K sats, we can launch everything from India, we will be almost independent

 

[Vamsi]

@Swesh @Okabe Rintarou @Indx TechStyle most probably either LVM3-M6 or M7 will be powered by SC120.

What about space station?

 

[Indx TechStyle]

Is 6 tons to GTO enough for a modular space station?

Depends on size of modules. Certain payloads will still require NGLV.

 

[Vamsi]

What about space station?

Its LEO capability will be close to 15Tons, so technically they can build modular station using it, but they are preferring NGLV for it

Any specifications of NGLV ?

 

[Vamsi]

Any specifications of NGLV ?

10T to GTO, 22T to LEO in Expendable mode
5T to GTO in Reusable mode

 

[Indx TechStyle]

Any specifications of NGLV ?

10 tonnes to GTO. 20~25 tonnes to LEO (maximum capacity variant).

Planned variants on two basis:

• Expendable versions and reusable versions.
• Methane engine based and semi cryo engine based.

I wish they finally adopt this layout as their basis for long term plans now.
