The rumored problem with hot gas thrusters on Starship is the relatively low pressure of the propellant tanks. Electric pumps solve that, but add complexity. But what about pulsed thrusters?

Mixture ratio could be addressed by placing the regulator *after* the accumulator, but my gut says they'd get trashed by the pressure spikes.

Now that I think about it, the average specific impulse of all this probably wouldn't be much better than a thruster that's just pressure-fed.

Christopher David (@Tazerface16) is a USNA Class of 1988 graduate who served in the Navy’s Civil Engineer Corps (Seabees/construction battalions) from 1988–1996. He later spent years as a semiconductor sales engineer at Teradyne and then as a medical lab scientist at the VA in Portland. MY Times reported his bio. He repeatedly claims a BS in aerospace engineering from the Naval Academy. USNA does offer that major, but his actual Navy career was civil/construction engineering, not aircraft or rockets. IF he ever studied aerospace, he was very bad at it. Mainly he trolls on X for engagement.
I mean he did ask us to bookmark it. He is ready for our response today, right? Right?

With a single search I managed to find 9 instances of him claiming Starship was incapable of reaching orbit with any payload.
0. He never argued that Starship will *never* make it to orbit with payloads, he pointed it out it kept failng & argued that Elon's promised timelines, not just to followers & investors but the government, were unrealistic, which they WERE. It's FY 2026.

Note that Phil has repeatedly claimed Starship has *zero* orbital payload capacity. Also note that today's payload was double the mass of the Space Shuttle's heaviest payload (Chandra).

Poor guy never learned about the inverse square law.
Rule of thumb for Mars fantasy renders is, if you can see the sky, you're getting all the tumors. If you want this view, go live in a Utah mall

Did SpaceX put buoys at multiple locations, or does Starship have an insane cross-range ability?

Elon Musk doesn't know about Soyuz 11.

Makes you wonder how many of the early "flying saucer" sightings were a YB-35 or YB-49.
These shots hit even harder when combined together. Unbelievable work by @JarodMHamilton

Rockets burning fossil fuel hydrocarbons: Great! Rockets burning carbon-neutral hydrocarbons: Literally a war crime.
Replying to @RealOtisCrune
Google me and see if I want to ban spaceflight lol

Someone should let farmers know they're war criminals.
If your hardware startup is engaged in pulling carbon out of the atmosphere just so you can *burn it again* you should probably be hauled in front of The Hague
