| Slightly OT, but I see the Chinese are talking about space DCs now too which would suggest they reckon it could work too. (Unlike me and others here) |

| Except none of that data center grade chips can work in the space. No GPUs, no memory, no SSD. They are not radiation-hardened (rad-hard). Rad-hard chips generally cost an oder of magnitude or more compared to normal commercial chips, and they are in general an order of magnitude less complex, plus they operate much lower frequencies. Data centers in space is straight up stupid. |

| datacenters in space are a great way to claim vast amount of viable orbit space for a stupid project to eventually sell the slot for something else when it’s rarer. |

| Not a physician, but wouldn't space be terrible for heat dissipation? |

| ▲ | ampersandwhich 2 hours ago | parent | next [-] | | Also not a rocket surgeon, but to my understanding, modern satellites already have solar panels and radiators that account for the system's overall energy absorption and dissipation in low Earth orbit [1]. Therefore, plugging a supercomputer into the solar array instead of another instrument would likely not affect the overall heat profile meaningfully. Most energy in LEO is ultimately derived from solar irradiance and passes through the spacecraft regardless of internal usage. That said, take this with a grain of salt due to the aforementioned lack of astrochirurgical bona fides. Edit: Added some primary sources [2][3][4], including an interactive website by Andrew McCalip which lets you play around with the unit economics of orbital 'datacenters' at various price points [4].

| I think it's more of a classic mirror move where IF they do work, they're at danger of falling behind. |
