Thank fuck

I haven't been keeping up to date. Are they launching S26 or S28 during ITF-3?

This is the literal cancer that killed 4chan. Election tourist from reddit that went straight to /pol/.

How far into testing Raptor 3 have they gotten?

Yes, I know about the S1.5400. I use it for some interplanetary missions in KSP RSS even, but material science has not evolved too much in regards to rocket engines, or at least to in making them less heavy. The material science that has evolved since then is more about alloys being able to handle hot oxygen better and changes to the metallurgy processes. And in regards to manufacturing it has become cheaper, faster and require less parts but not necessarily better performance. You still have engines designed and produced in the 60's that mog pretty much any engine today besides the Raptor (like NK-33, RD-57 and RD-270 to mention a few).

For a modern example Rocket Factory Augsburg has made a kerolox ORSC engine named Helix at 100kN, but its pretty heavy for that class iirc.

Enough about this soyuz vs falcon faggotry. Which hypergolic fuel/oxidizer combo is the most based?
