Any particular reason you wouldnt live in the EU? Aside from the hassle of uplifting ones life and such.

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 don't understand how a lack of regulation would mean some

As a spacecraft integration engineer, I assure you it is not.

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 went so wrong in this instance though. I am looking forward to

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 the leaks here are a lot more serious. My experience of signi

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. Its hard to care about the 15th castle you pass in as many min

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 reasonably large items. They arrange an DHL pickup and drop, with a l

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 will take a lot of convincing that it is as good

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 scale are closer to car manufacture, so for harnessing, they

Apologies, yes the crimping standard specifically is here: https://ecss.nl/standard/ecss-q-st-70-26c-crimping-of-high-r...

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.

The main brands I would see would be Glenair, Souriau, and ITT Canon. Once you are paying the the space quality hardware, its all much of a muchness really. Glenair would probably be top dogs in this space. I have used other manufactures wi

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 the Boeing crimpers, and I have worked with the SpaceX guys,

Hahaha oh yeah, plenty. Recently the Peregrine Lander had wiring issues that led to using the NASA payload to perform the landing. The Vega-C launcher was lost not long ago as two connectors were swapped, connecting two engines in reverse o

Havent used them much, but I cant see why they would need to be tinned.

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 mis-crimp. For under/over crimping, thats mostly taken

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

As you say, things shift around, promises get made, everything gets delayed and all of a sudden there is no margin left. Unfortunately AIT has to do all of the hardware work with no margin so much of the time. Secretly I love the power that

At undergraduate level I studied Physics and Astronomy, and then did a research MSc as an optical astronomer, which I hated and drove me away from Physics and Astronomy as a whole. I spent a few years working in IT Support before deciding t

As a spacecraft Assembly, Integration and Test (AIT) Engineer, one of my areas of expertise is harness manufacture and routing. So this naturally involves an awful lot of crimping. I am a certified crimping operator and inspector under the

Oh hey! Congrats on the awesome mission!

Love to answer questions if I can. 1. The testing culture is very thorough. I was involved on the propulsion side of things, and as such the safety is taken very seriously, for the safety of the test/production engineers and of course

I wouldn't want to go into specifics, as it's easy to look like I was slinging mud. But if you have seen the issues that Starliner has had recently, I would echo the statement from there, that valves are hard. Very hard. Everythin

Quite a small part, but yeah, the science missions are always special to be a part of, even if its small.

Always a bit special to see science come from a spacecraft I had the pleasure of working on. Honestly there were a lot of issues during the build of Euclid that I was very glad to not be a part of, but seeing the images coming out of it now

Where do you source your ACF? Out of the blue, I am faced with needing this tape on the day I first learn of it.
