SLS Block 2 Cargo

The Space Launch System (SLS) is a super heavy-lift expendable launch vehicle, which has been under development in the US since its announcement in 2011.

This is the SLS Block 2 Cargo, useful for lifting heavy payloads, heavier than the Block 1 can lift.

You can see the difference by looking at its boosters and the fairing. The fairing is larger because the payload is heavy, heavy means bigger. And you can see the SRBs are different, these SRBs are very powerful, the world's most powerful SRB. Because, Block 2 Cargo is used for Super Heavy-lift.

core stage

The core stage uses the RS-25 Engine. The space shuttle actually uses this engine, too. The core stage diameter is 8.4m, that's the same diameter as the space shuttle external tank! Well, it's just a longer external tank but with an engine attached onto it. The length is 65m.

We need mach diamond.

Second stage

Or we can call it, Exploration Upper Stage. It uses liquid hydrogen (Hydrolox) as fuel. And RL10 as an engine.

Edit: Damn it, I forgot to resize the fairing. Sorry for that.

I should've posted this yesterday but I'm very busy yesterday. And I'm still making KSP crafts, it will take a while.

Edit, again: thx for 800!
