Because they’re highly sensitive materials.

They’re working with very complex electronics, delicate things.

When you take your computer to a repair shop (or repair it yourself) you take some precautions to make sure you don’t get a ton of dust/dirt/anything on it, rubber gloves, air cans, a clean work space, stuff like that.

But say you screw up and somehow a tiny little piece of dirt or metal gets onto your motherboard or cpu and causes a short or messed it up in some form. The worst outcome for you is you have to go spend a couple hundred dollars to replace it.

But you can’t do that with a satellite in space, you can just go replace a part that breaks. So you need to do everything possible to keep that part from ever breaking, keeping it perfectly pristine.
