About cuSetanta
Aside from engineering, I have a background in Physics and Astronomy, and I have done my time in IT Support (for my sins).
I love to talk about my work and the space field as a whole, so feel free to message me if you want to know anything.
Feel free to stalk me in these places: https://ptisdall.github.io/ https://www.linkedin.com/in/ptisdall/

There are regulations around de-orbiting your spacecraft at end-of-life, and there are international agreements around weapons in space that refer to the generation of debris. I do…

It will have been tested extensively on ground. They will have identified leaks that are unreported in the media and there are those that have been reported. I have no idea what we…

A certain leak rate is expected. Helium is a very small atom, and as such is used for leak testing of systems all the time. It is very good at finding gaps in a system. Obviously t…

Lived in a small town along the Jagst river for a while, which joins the Neckar at Heilbronn. You get Castle Fatigue fairly quickly with how many castles there are around there. It…

I have moved around a fair bit in the past decade, and for me the most effective movers I have used have been SendMyBag [1]. They are great for shipping luggage and other reasonabl…

I would also add that the 'New Space' scene is going to be much more willing to accept autonomous manufacturing methods. People like ESA are much much more resistant to change, and…

Space is very slow to change, and traditional harnessing is going anywhere for the time being. I cannot speak to the newer systems on the market like Starlink, their economies of s…

18 gauge! Thats the big leagues. We rarely go that big, 22awg is big for us. I salute you sir.

If you have a fish scale, you can see what the retention force is fairly easy. Thats the primary method we use for calibration, albeit with a specific testing hardware.

Crimping is essentially quite a low skill method of connecting wires, when compared to the high skill and experience to do it reliably with solder. I would have a lot of trust in t…

The inspection is primarily visual, to ensure that the stands are well aligned in the crimp, with no protrusions. And to check there is no damage to the wire due to stripping or a …

Nordlock washers are the best, but they are expensive and a little space inefficient.
