Musk responded to the discussion about space data centers, emphasizing the scale advantage of SpaceX with over 10,000 satellites in orbit.

According to Mars Finance, on June 16th, the discussion surrounding the "engineering feasibility of heat dissipation for space data centers" continued to escalate. User XFreeze posted an article pointing out that space data centers are not science fiction; their core relies on proven thermodynamics and aerospace engineering systems, rather than new physical breakthroughs. The post explained in detail that in Earth's environment, data center heat dissipation primarily relies on air convection, water cooling, fans, and cooling towers. However, in a vacuum environment, heat cannot be dissipated to the outside through convection or conduction. Therefore, a completely different path must be adopted: the heat generated by the chips is directed into a liquid cooling circulation system, pumped into large radiating plates, and then released into deep space as infrared radiation. This essentially follows the Stefan-Boltzmann law, which states that radiant power is proportional to the fourth power of the radiating area, emissivity, and temperature. This mechanism is not a theoretical concept but a mature technology system long used in spacecraft such as the International Space Station (ISS). The ISS continuously radiates heat generated by equipment and life support systems into space through pump-driven cooling loops and large external heat sinks. The difference lies only in scale and power density, not in the physical principles themselves. Based on this, the user believes that the engineering challenge of a "space data center" lies not in physical feasibility, but in system-level scalability, including how to deploy large-area radiators in orbit, how to increase the upper limit of material temperature resistance, how to optimize liquid cooling cycle efficiency, and how to match continuous and stable power input with communication links. He pointed out that SpaceX's "AI1" type orbital data center concept relies on a deployable large-scale liquid cooling structure and a high-power solar energy system to solve the coupling problem between computing power and thermal management. Subsequently, Musk responded that SpaceX has more than 10,000 satellites in orbit, a scale "far exceeding the sum of all other space systems," thus the company has ample experience in orbital system operation and space infrastructure. He did not directly comment on the specific design of the space data center, but this statement was interpreted by the outside world as an emphasis on SpaceX's on-orbit engineering capabilities and experience in large-scale system deployment.
