Could it be? Flight Grayloc? My beloved?
I can’t imagine this would be shown in the engines post if it were GSE. The OTW would also point to a flight article.

More than 800 Rutherford engines have been launched to space and this year we plan to exceed 1,000 total. 3D printing helped to make that scale possible. Like Rutherford, Neutron's Archimedes engine features 3D printed parts, including turbo pump housings, thrust chamber, valve housings, and engine structural components.

Also … angle error given line of action is not parallel to the strut travel … just sayin

String potentiometer visible on the MLG struts (and string on the NLG strut). These are F-16 gears - interesting to see them still being experimentally evaluated after first flight (if this is indeed a pre-flight-2 preparatory ground test)

NASA’s X-59 is prepping for its second flight ✈️ NASA test pilot Jim “Clue” Less will pilot the X-59 for the second flight. The flight marks the beginning of “envelope expansion,” where the quiet supersonic jet will start flight testing at faster speeds and higher altitudes. Ultimately, the X-59 will demonstrate that an aircraft can fly faster than the speed of sound while reducing the typical loud sonic boom to a quieter thump. 🔗: go.nasa.gov/3PeCq56

I’d like to think these speakers were just playing “I’m Blue” for 10 mins at max volume … testing engineering is … in fact … very expensive performance art

This week we completed direct field acoustic testing on our Blue Moon MK1 lunar lander, a major flight‑qualification milestone. We surrounded the fully integrated lander with a ring of 34‑ft speaker towers to generate a near‑diffuse acoustic field, matching the New Glenn payload fairing environment at over 138 decibels overall sound pressure level. MK1 ran in a flight-like configuration: tanks pressurized with helium and nitrogen, batteries powering the vehicle, with all critical avionics and guidance systems operating. 43 triaxial accelerometers measured response during a two‑minute exposure at protoqualification levels. Because the lander's vibration environment is driven by acoustic loads, this test replaces traditional shaker-based vibration testing and more accurately represents ascent conditions. Next stop: @NASA_Johnson for thermal vacuum chamber testing.

Towed by a dump/plow truck? No suspension on the casters? Fascinating rig

LR-64 sustainer from a AQM37 Jayhawk target drone. DM offers. Super clean.

@rktpoweredkeith Any idea on original use? Also curious - any idea what fitting that is?

After being shipped from Atlanta, Quarterhorse Mk 2.1 has arrived at Spaceport America — our new home for the next chapter. The journey to first flight starts now.
Capable of reaching supersonic speeds, Quarterhorse will be the world's first high-Mach unmanned aircraft for national defense.

Anyone know what the other vertical structure is on their Mojave site?

That’s a wrap on 2025: the year Vast became the only operational commercial space station company to fly and operate its own spacecraft in orbit with Haven Demo. Onward to 2026.

Elusive flight swivel union? (Probably not … lock like drag-on since no support for the PT, alas)

Two E-2 development engines are fully assembled and undergoing test campaigns to validate reliability and service life. In parallel, our team is rolling out an upgraded design that is lighter, simpler, and incorporates thrust vector control. E-2 is ~75% 3D-printed by mass, produced in-house by our highly skilled manufacturing team. The highest performance LOX/kerosene engine in the small launch class is made in America 🇺🇸

2025 was a big year—securing approvals for Australia’s 1st sovereign orbital launch, deploying our 100kg ElaraSat🛰️, expanding manufacturing & gathering key data from #Testflight1 at Bowen Orbital Spaceport.
Here’s a look behind-the-scenes, as told by our 🌟team.
We’ll be back!

On strict near-term unit economics, this might still be a mediocre use of capital. A tilt-wall datacenter in Oregon with cheap power, cheap cooling, and technicians on call is hard to beat. Crusoe can park compute on stranded natural gas and turn it into flops with a supply chain that already exists. But the knock-on effects are why this keeps pulling at people. If you can industrialize power and operations in orbit at meaningful scale, you’re not just running GPUs. You’re building a new kind of infrastructure that makes it easier for humans to keep spreading out. Compute is just one of the first excuses to pay for the scaffolding. Even if this is a mediocre trade on strict near-term unit economics, the second-order effects could be enormous. I’ll go one step further and say the quiet part out loud: we should be actively goading more billionaires into spending on irrational, high-variance projects that might actually advance civilization. I feel genuine secondhand embarrassment watching people spend their fortunes on yachts and status cosplay. No one cares about your Loro Piana. If you’ve built an empire, the best possible use of it is to burn its capital like a torch and light up a corner of the future. Pay for the iteration loops. Build the cathedrals. This is how we advance civilization.
