ISRO Tests India's Largest Cryogenic Engine For 400-Ton Rocket

The launch cost of super heavy falcon will be around USD 90m. It would have 22,200 kg of gto payload capacity. Basic math says usd 4054/KG of launch cost.

Falcon 9 FT cost $62 million for 5.5 tonnes to GTO.

?

I might have used '9' liberally in earlier post. I meant Falcon Super heavy as has been mentioned in my last post also !

I guess spaceX's current estimate for its falcon heavy launch vehicle is USD3950/KG

Yeah, a lot of their development costs were borne by NASA during the cold war . Its not really any massive inherent crazy efficiency they have stumbled upon overall ...though I appreciate the way they have operationalised this, unlocked and promoted it.

It will help to drive down costs worldwide.

Falcon heavy gives $90 million for 8 tonne (reusable)

This needs to brought down to usd 1600/kg for us to be a viable space faring civilization ! ( Not sure of the source for this but I heard Elon Musk talking about the numbers in a published interview )

Ever heard of Bellatrix Aerospace?

Don't act like a teenage kid. Even your article points to 22,200 KG performance of Falcon heavy. The 8T probably will be the first payload weight !

What about it ?

China's newest launch vehicle CZ-5 uses both engines. The boosters use semi-cryogenic engines, and the core and upper stage use cryogenic engines.

I meant they went ahead with research of SCE first.....!!

Dude, reusability. 22 tonne to GTO is the payload for expendable version.

The payload varies with the number of boosters meant to be recovered.

Where I basically see this netting out is Falcon 9 will do satellites up to roughly 3.5 tonnes, with full reusability of the boost stage, and Falcon Heavy will do satellites up to 7 tonnes with full reusability of the all three boost stages

Never mind,

Could be Indian SpaceX if materialzed it's goals, for now it's nowhere near.

China had its first cryogenic engine YF-73 in 1987, long before its current generation of semi-cryogenic engine YF-100 (2015) and cryogenic engines YF-77 (2016). They have used YF-73 from 1980's to 2000's, replaced it with the newer cryogenic engine YF-75 in 1994.
