Miku, your mentor at Mecodyne, leaves a note: do not press Run Test. You press Run Test. A real engine spins up, the graphs start moving, and that is your first day on the job.

got some new tooling, so finally back to the liquid rocket project! this is the business end, more or less.
one piece = aft N2O bulkhead, N2O valve housing, e85/fuel manifold, injector, and N2O fill inlet
trying my best to not mess it up lol

Sound🔊on: epic fly-by footage of the ongoing Zenith engine testing and Stage 1 structural qualifications happening at our test site in Moses Lake. 🤘🚀

I almost broke my hand while celebrating this 🤕
Because on the 13th of May, after 6 months of relentlessly trying to find the right process to light up the engine with its turbopump, we finally did it right.
Not once, but multiple times. With reproducible results.

Three ways to play: work the missions, an engineering ladder with tongue-in-cheek safety hazards. Free-build on an empty canvas with live graphs. Or recreate real hardware like the Merlin 1D and the F-1, same components, same physics.

Your first dozen designs fail in interesting ways: red graphs, exceeded margins, the engine throwing a tantrum on the test stand. Then a self-sustaining turbopump picks its own speed and you just hope it picked a good one. That's where you learn.

Meco 0.5 ships with a new first day on the job. Miku leaves a note: don't press Run Test, I'm in a meeting. You press Run Test anyway. A real Vulcain engine spins up on your screen. So much for the note.

Three new missions: turbopump integration (Vulcain-style direct-drive shaft), a complete F-1 gas generator cycle that has to converge on its own, and coaxial injector design with LOX posts and hydrogen annuli.

Every mission intro is now a lip-synced cinematic, so your mission director actually speaks the briefing. I build Meco on my own, so if you play and have a minute, a Steam review genuinely moves the needle.

We go where we need to be, and today that was @NASAKennedy.
Some of my senior engineers and I spent time at @blueorigin with @JeffBezos and @davill, speaking with the workforce and seeing the damage at LC-36 firsthand. I appreciated the opportunity to hear directly from those working through the aftermath and better understand the challenges ahead.
There is a lot of work to do, but this is exactly why people choose careers in aerospace, whether at NASA, Blue Origin, or across the industry. The talent in this field thrives under pressure and performs at its best when solving the toughest problems.
We have been saying for months at NASA that we are not going to sit on our hands and wait for the capabilities necessary to achieve the nation’s most pressing objectives. We are going to take an active role alongside our partners, just as we did in the 1960s, to overcome setbacks, remove obstacles, and deliver the intended outcomes.
@NASA is committed to helping the Blue team recover, continue to advance their lunar lander and get New Glenn back to launching as soon as safely possible.
America’s greatest achievements in space were never the result of avoiding setbacks. They came from overcoming them. We have done it before, and we will do it again🇺🇸

🚀 Some engines move vehicles. Others launch rockets.
Motorcycle, car, truck, aircraft… and Vulcain® 2.1 all rely on propulsion, but not at the same scale.
