Is it true that "space is so cold that heat dissipation is easy"? Cooling, essential to making space data centers a reality (Part 1/2)

As AI data centers proliferate, companies are advancing orbital data center concepts that can use abundant solar power in space.

But cooling is a major hurdle: in vacuum, heat cannot be removed by convection or water cooling, so systems must rely on radiation.

That means high-heat AI chips will need not only radiators but also new heat-transport technologies to move thermal energy efficiently.

The idea is attractive for easing limits on power, land, and water on Earth, but space-specific thermal design remains a key blocker.
