Max Oberg

I have created "So You Want To Design a Pintle Injector" Hopefully someone who knows almost nothing about designing rocket engines, can pick this up and understand it from beginning to end. Feedback is seriously welcomed! This is my first try at this maxoberg.dev/project_update…

Go see Project Hail Marry in theaters. It is completely worth it and so so good

Job 👀

@stefan_salaices JIC my beloved

Really tried to see that Firefly launch from SF, but it just ended up being me trying to catch eye floaters in my vision as I took in a blue sky

@TylerG1998 But are you wearing sunglasses

It’s 498 miles to West Texas, 🗺️ I’ve got a full tank of gas, ⛽️ 6 cameras, 📸 plenty of camping supplies, ⛺️ and a lunar eclipse to catch. 🌕 Let’s hit it. 🕶️

@StormSilvawalk1 That’s a real nice noise

The first full, integrated, test of my liquid rocket engine turbopump with cryogenic propellant! It has taken me 3 years from paper to this test run and a lot of blood, sweat, and tears. There is lots to change and improve, but overall not a bad first integrated run. Sound on:

Definitely gave me this type of feeling though. But dammit, ai is kinda dumb when you get down to it.

I made a thing: maxoberg.dev/projects/2026-…

First time hitting a vibe-coding Cursor token cap - Is this something to be proud of? I definitely feel weirdly accomplished

Slow motion photography in black and white can make any rocket injector flow look cool

@eigenrobot Man do I agree with this take. With some caveats where visual displays are necessary, just write the damn thing. In the age of ai though, finding good writing is hard when you have to sift through ai generated articles first

i hate video content more than anything getting information from people talking is like trying to satiate yourself by eating lettuce. near zero value density. this is an incredible imposition on the infovore's time

@DJSnM Man that symposium gets cooler every year goddamn

This weekend I’m in SoCal at the liquid propulsion symposium, which also happens to be at the home of the original EAA chapter

@dpoddolphinpro @flightradar24 @ADSBex This is the one aircraft I have email notifications turned on for on FlightAware. That’s unfortunate

Quick analysis of today's WB-57 belly landing: ADS-B tracking data from @Flightradar24 & @ADSBex suggests that the WB-57 (Registration N927NA / Callsign NASA927) came to a stop at approximately 17:20Z (11:20L) on Runway 17R at Ellington Field (KEFD). ~2.5 minutes before crash Listening into the Ellington Tower replay audio from @LiveATC, NASA927 requests a touch-and-go from KEFD Tower. KEFD Tower approves a touch-and-go for Rwy 17R. NASA927 reads back this clearance. This is the last transmission from NASA927 recorded. ~2.5 - 0 minutes before crash There were no communications recorded from/between NASA927 in this period. Approximately ~1.5 minutes before the crash, KEFD Tower asks a following aircraft to switch to Rwy 17L. It is unknown if this request is related to N927NA's location at all. Approximate moment of crash KEFD Tower slightly steps on the end of another aircraft's call, saying "NASA927?". There is no reply. ~30 seconds after crash The Tower controller hands over control to another controller. ~40 seconds after crash The new Tower controller confirms that they have "a WB-57 crash on the runway [...] Right now 17R is not usable". Weather The closest METAR report to the accident was taken at 16:54Z (10:54L), approximately 26 minutes before the crash. Wind: None Temperature: 6°C Visibility: 10 miles Cloud ceiling: None Pressure: 30.58inHg Conclusion At no point on NASA927's final final approach was there any recorded mention of landing gear problems, an intentional no-gear landing, etc. NASA927 had been flying multiple circuits of KEFD today, conducting touch-and-gos on 17R. To emphasize: this analysis is purely based on ADS-B data and audio recordings available online. This data may be incomplete or incorrect. We await the official NASA report. 📷 @KHOU

@FaultedBeing If it's fixed maybe. If it's on a TVC you're going to get some weird precession

Is there a net moment axially from the momentum flux of the fluid going in a helix? I know of one other kerelox engine with helical cooling channels that had this issue.

@HankCouture I'm a big proponent of HS rocketry teams personally (completely not biased what so ever of course having founded one myself)

#1 thing to accelerate US innovation the next 10-20 years will be making sure every high school + middle school in America has a robotics team + resources for it if you talk to enough young builders, the most common theme is their love to build started in 8th grade robotics

@rktpoweredkeith One day, one day I hope to own one of these pieces of history

Two LR-101 chambers. DM offers.

@planet4589 Just remember about this. Is there any new update? Hope alls going well!

Jonathan's Space Library will be moving to Bromley, south of London, at end 2025. Still to do: - Complete purchase of property - Planning approval for renovation - Construction, and shipping! gofundme.com/f/fund-jonatha… Funds still needed

Managed to grab this pic of the red aurora glow in Colorado before the numbness in my toes forced me to descend the mountain
