Missing the most important piece of info about any NRO launch, the mission patch! Meow! https://www.nro.gov/portals/135/assets/img/L-70_Snow-Leopard...

That isn't a real patch, more of a mission logo. The details are too small. The pink nose, if actually in patch form, would stand out as a pink dot in the middle of a blurry cat.

Fyi, military patches look best when using lines with fixed-width. Anything pointy or jagged doesn't translate well into stitched thread. Avoid shadows too. Yes, there are some all-plastic patches that are carved into 3d shapes but those are evil. Real patches are thread over velcro.

There's a general term for this, designing for manufacturability[0].

I've made something of a hobby of learning new ways to manufacture things. Every time I learn a new manufacturing technique I start to notice things that were made that way in the real world, and I especially start to notice aspects of design that would have been influenced by how the thing in question was manufactured.

Case in point: injection molding. When you injection mold parts, the sides have to be tapered so that the part can detach from the mold easily (the term of art for that is "drafting"[1]). Once you know that, you see it everywhere.

Back to the topic at hand: owning an embroidery machine and learning how to digitize completely opened my mind to all the intricacies of patch design and why all of what the parent comment said is true. Case in point:

> military patches look best when using lines with fixed-width

This is because the thread itself is fixed width, and you can either do a straight stitch for really thin lines (they call that a running stitch[2]) or you can do a sort of zigzag stitch that's so tight that the thread runs horizontally and fills up the line width (they call that a satin stitch[3]). Satin stitches only look good within a certain narrow range of widths; wider and the threads are too loose, narrower and the needle holes are close enough that they impact the structural integrity of the backing the design's being embroidered on to.

Anyway. I could go on for hours, but to wrap up: DFM is a fascinating world to explore.

I'm actually very very interested in this opinionated approach to patch design -- can you tell me more? Or refer me to some useful design guides? I can just google something random too, but it sounds like you might know / have some good resources already
The term you'll want to search for is "digitizing". It's roughly the embroidery equivalent of CAM design in CNC manufacturing.

Depending on how much time you have, this video[0] is a decent in-depth overview[1] of the various ins and outs of embroidery patch digitizing. I'd give it a watch while you're on a walk or something.

[1] Heh, "in-depth overview" sounds like a total oxymoron. Hopefully you get what I meant!

Nothing will ever top NROL-39 with the octopus

There's a lot of in-jokes and humor in the defense contractor community for team morale building and such. Same idea why challenge coins exist within the relationships between big defense contractors and the DoD agencies that buy services and equipment from them.

The "nothing is beyond our reach" and octopus seems like some sinister and scary thing for a military/intelligence agency to be putting out there in public, but it probably has a more specific meaning within the top secret capabilities of that specific program. I have no idea what it is, could be something like listening to all mobile phone traffic in Waziristan, whatever.

Is it just me, but I feel like this being an NRO patch that the placement of the stars isn't just a designer's choice but potentially some cryptic meaning. If not, how boring!
Look up Trevor Paglen's book "I could tell you but then you would have to be destroyed by me". It's a collection of mission patches along with some interpretation as to the meaning and placement of symbols. Fascinating stuff.
My guess: there’s 3 stars that are brighter, and the cat is shown with 3 legs, so it could be part of a constellation of 3 satellites. The swoop of the tail could indicate a molyina orbit. Generally the orbit and where these things are in the sky can, and are, tracked even by hobbyists so that’s not particularly juicy, imo
These patches are allowed to leak exactly 0 bits of meaningful non-public information about the payload.
