30ton LEO Soorya is not base variant, it's the heavy variant, base variant i.e SOORYA-CA has 20ton LEO, while SOORYA-H has 30ton LEO

You sure?

You sure?

Yes

There are three variants it seems. 30 Ton maybe with 4 SLBs.

Wasn't this launch from early 2023

One more how they collect the stage to reuse it ? No details about it

 

[Varoon4]

Right. This is the second launch, as you say. It is a sounding rocket. Hope it is a stepping stone to larger reusable rockets. Not bad.

 

[Blademaster]

We only have 2-3 real competitors out of nearly 200 countries in future anyway.

And those two-three competitors outrage us by a huge mile or more. Still a low bar.

Yes,There are 3 variants
1. Soorya-core alone - 20T LEO
2.Soory-heavy with 2 SRBs- 30T LEO
These 2 designs are finalised
3.Soorya-super heavy with 2 Liquid boosters (similar to Falcon heavy & Longmarch-10) - 70T to LEO for manned moon mission, still under conceptual study phase

Most likely parachute

Which liquid boosters? Those SCE-200s or new methane engines, eitherway clustering will be required, I hope they bump up s200 to a new s450 level or with clustering sce-200 reach close to rd-170, but that is another monster, it uses only single turbine to generate that much power.

LOX-Methane boosters powered by 9 LME-1100 engines

 

[Blademaster]

Yes

Wiki says up to 49 tons.

 

[Anonymous Bharata]

Wiki says up to 49 tons.

That's one version, there's another larger version with more propellant loading under conceptual study phase

A respected, knowledgeable commentor has called this launch hype and rubbish. Given the number of start ups claiming things, you could understand his disdain. But what about the huge number of payloads( pico sats) on board the rocket? Would this give a certain respectability to the mission? Also, the hybrid character of the propellant.

Two URSC patents related to spacecraft capturing mechanisms for On-Orbit Satellite Servicing.

1) Short description of invention : Liquid Apogee Motor (LAM) Throat Capturing and Preloading (LTCP) mechanism for On-Orbit Servicing (OOS) to extend the life of non-cooperative spacecraft in LEO or GEO nearing end-of-life.

2) Short description of invention : Launch Adapter Ring (LAR) Grasping and Preloading Mechanism (GPM) for On-Orbit Servicing (OOS) to extend the life of non-cooperative spacecraft in LEO or GEO nearing end-of-life. With a lightweight design under 2 kg, the GPM can handle client spacecraft weighing up to 1.5 tons. Its compact gripper reduces overall system mass and complexity, making it suitable for various applications, including refueling defunct spacecrafts and performing berthing operations on the Indian Space Station.

I can see Space based ASAT here, capture enemy satellite & deorbit it, especially LEO based Reconsats
