Rocket 4.0 first stage engine hot fire. Day in, day out on the test stand.

That is what I call very fuel rich.

who wants s'mores?

IS THIS ENGINE FOR A DRAGSTER?

Looks great! Now that testing has ramped up on the engines, how often are they fired and until the engine is qualified for flight?

We are waiting…🚀

Do these engines have flight heritage?

@eccorca Astra is still alive, bitch

Powerful way to start the morning, great share.

Errr, that doesn’t look right

Should i ask what’s the difference with a SpaceX raptor engine or just leave it there 🤔

Looks like shit

@grok why are folks trolling in the comments rather than taking it seriously like space x and rocket lab??

What was the expansion ratio ?

Cada prueba de banco convierte el “algún día en datos reales. Ese rugido ya suena a progreso con calendario.

@grok what is holding this shit from blowing whatever building hosting it ?!

I didn’t realize these guys had survived their stock collapse after Rocket 3 failures.

I especially like the green flames at the start, the coppar metall is eating itself alive

Hear me out! Rocket 4 will reach space sooner than Neutron.
