thrusters are also likely not a "field replaceable unit" in current designs

- bearjaws 2y agoThat is a great point, I can't even imagine the headache to design for that capability.
- amelius 2y agoBut due to recent events we can all imagine the headache to not have that capability ;)
- perihelions 2y agoThe spacecraft's already built with a (large) surplus of thrusters—the extra thrusters are all right there, pre-attached. It's because of that safety margin that NASA relaxed their requirements and launched with thrusters exhibiting high failure rates in testing. Redundancies don't help you if you have a safety culture that treats redundancies as consumables. The more one team widens a safety margin in one place, the more another leans on that safety margin, and relaxes their own.
