Space and stuff.

[World of Engineering @engineers_feed]

Voyager 1 is 24 billion kilometers from Earth.

It communicates with us using a 23-watt transmitter.
Less than a refrigerator light bulb.

The signal takes 22 hours to reach us, traveling at the speed of light.

By the time it arrives, it's 20 billion times weaker than the power of a digital watch battery.

NASA's Deep Space Network picks it up using 70-meter dish antennas cooled to near absolute zero to reduce electronic noise.

The engineering required to hear a 23-watt signal from 24 billion km away is arguably more impressive than the spacecraft itself.

Launched 1977.
Still transmitting.
Still being heard.

We built something that works perfectly, 47 years later, in conditions no one has ever tested in.

That's what engineering for the long term looks like.

@chrisschmitz If you link it I’d love to see!

CFD test of the alleged Area 51 craft spotted in recent IR/thermal imagery (structure seems to be a mix of the X-36 and the Bird of Prey).
Four-regime Mach sweep: M0.8, M1.1, M2.0, M3.0. 2D Euler Simulation only, but the silhouette is wild.

Video footage posted recently by the YouTube channel Project Fear, filmed near Area 51 at the Nevada Test and Training Range (NTTR), appears to have captured a new sixth-generation fighter aircraft, possibly the U.S. Air Force’s Next Generation Air Dominance (NGAD), known more commonly as the Boeing F-47.

Friday night fun: testing out a local CFD simulation. 2D finite-volume Euler simulation of compressible flow over a wedge. Flow begins subsonic, crosses through transonic conditions, accelerates into a supersonic regime, and finishes hypersonic at Mach 5. Things still to tweak.

@i2cjak "something cool to be granted ACCESS"

@DrChrisCombs When I saw this in person at NMUSAF, I as promptly introduced to the concept of a "scaled prototype" for the first time.

@AnnieJacobsen It was awesome to see/capture in person. On exfiltration I was sand blasted from the rotor wash.

Paying respects to one of the GOATs in aerospace.

@ShorealoneFilms What’s the spotting play tonight?!

[AnalyzeThat @test_user_X1]

@Xaraphim @RatioDrones Best of luck with it. I was reading the competition requirements a few months back and it looks like it'll be a great event. Be sure to visit the XB-70 while you're there. She enjoys some visitors.

@amypretzel Not sure when/how the cad program came into being...but check out the work of @ruben_kostard on his @ForgeCAD with Agentic AI

@ApoStructura Close enough. Welcome Back Lockheed D-21.

@servomechanica @ShorealoneFilms I recognized this mission immediately. Friggen tight corridors. MOBIUS ONE FOX TWO.

@i2cjak Both competitors start with the same functioning board. Winner is whoever can shrink the fully-routed, DRC-passing design into the smallest absolute square millimeter footprint after 30 min without adding additional layers.

@ulalaunch What's the max stack weight (LV + tower) that railcar GSE can support?

@jimbelosic @zanehengsperger Doubles as a nice playset for the kids (or adults alike)!

@ReedTimmerUSA @WillClay25 @chaser_summit @localmanweather What's the sample rate per second on these units? Assuming they transmit live, with the electrical interference of some of these supercells, do you readily have packet loss?
