The unit economics of orbital DC just doesn't work with today's technology. Assuming 0 ongoing OpEx(free energy), the launch cost of the satellite itself, along with solar panels, radiators as well as the chip themselves just doesn't make sense given the ~5 year operational lifespan of both the chips and the satellites.
- dzhiurgis 5mo agoChips yea, but sats can last much longer. Chips are relatively lightweight, so replacing them in a new mission absolutely makes sense.
- yibg 5mo agoLEO satellite orbits decay. e.g. starlink sats are ~5 year lifespan. But assuming a higher, more stable orbit, how do you replace them? There will be tens of thousands of these orbital DCs, so not really feasible to go to each one to replace some chips. Or alternatively I guess a few massive ones, but those would need to be truly massive to accommodate the solar panels and radiator fins required.
- dzhiurgis 5mo agoWe already re-supply ISS. IDK how much of it can be done autonomously, but no doubt we'll do hella lot more in future if space economy grows. For orbits, those can and will be raised if it makes economical sense.
- yibg 5mo agoWe re-supply a single ISS. If all of this compute is in a single DC the solar panels and radiator fins will be the size of a small state.
