World's first open-source turbopump successfully tested. Developing 35 kW of shaft power spinning at 26000 rpm, it delivered 1.8 l/s at 90 bar, with the gas generator and turbine running at up to 1300°C for 15 s. No significant damage recorded.

I've been working on a really fun video that I shot with @DJSnM, @Integza__ and @JamesWhomsley when we were at Kennedy Space Center Visitors complex. It's over an hour of just 4 nerds nerding out about rockets in an incredible museum. I'll hopefully get it out tomorrow!

The difference between a bomb and a rocket is a well designed hole we call a nozzle. I'm really happy Grok doesn't censor every little thing that seems shady because every time I ask anything about rockets to ChatGPT it assumes l'm trying to make a bomb and tells me to go suck on a tomato. What's the point of having an artificial entity (you pay for!!!) to find and explain complex information if it only accepts "safe" questions???? Grok is great, it helps me find the right size hole without asking questions or judging me.

For a 2-stage spaceshot, high altitude ignition of the second stage is tricky to get right. My approach here is to dump a ton of heat into the prop as quickly as possible - this shot from Super 8 was 1000fps, played back at about 2.4% speed. The command-to-steady state time is about 0.25 sec
Large solid rocket motors are surprisingly hard to light. They need ignition systems that can deliver lots of heat and pressure quickly, and head-end ignition solves that.

Open Sauce 2025! What a phenomenal event - I can’t recommend it highly enough. It’s like an enormous adult science fair for nerds and then sometimes there are astronauts

I motion tracked go pro footage of Booster 15's landing to show the full on aerobatics this 20-something story building equivalent has to do to pull off being caught by the tower. Neat. @NASASpaceflight

There are few things on earth that will humble a mechanical engineer quite as much as having to assemble or manufacture something they themselves designed.
