It amuses me that of course there's a standard for docking interoperability defined:

https://en.wikipedia.org/wiki/International_Docking_System_S...

And adapters:

> The International Docking Adapter (IDA) converts older Russian APAS-95 docking systems to the International Docking System Standard

Imagine flying all the way and then realizing you forgot your adapter...



Maybe they just need to flip it twice like inserting USB devices.


It's always the second flip


The first flip collapses the wave function so that it has a definite orientation at all. The second flip then achieves the correct orientation.


The wavefunction collapses on the first attempt to plug in: it's always the wrong way.


If that were true then it would work on the second try. In reality it's always the wrong way on the second try.


The second flip is to rotate it around the 4th axis.


nope.. its symmetrical about a bunch of axes. at most they'd need a 60 degree rotation, not 180 like USB-A. So this standard is precisely 3x better than USB-A


How many times better is a barrel jack?


infinity times better, obviously.


Adapters are installed on the ISS


The adapters are installed on the station, the vehicles don't carry them.
