Overview

Review and critique of the feasibility of data centers in space, covering launch costs, heat dissipation, radiation effects, and long-term maintenance challenges.

Key Takeaways

• Space data centers offer theoretical advantages (solar power, low ambient temperatures) but face steep launch, maintenance, and radiation costs.
• Heat dissipation and single-event upsets (radiation-induced bit flips) are critical engineering challenges.
• At present, space data centers are an early-option concept rather than a near-term replacement for ground facilities.

Excerpt: Intro

Summarizes the concept of space-based data centers and the main engineering questions they raise.

Excerpt: Details

Discusses heat rejection, radiation mitigation, launch economics, and the maintenance overhead of orbital infrastructure.

Excerpt: Conclusion

Concludes that space data centers are interesting conceptually but face significant near-term barriers compared to terrestrial systems.

What is the experience of seeing the four evils of physics?
The four evils of physics know Xue Dinge's cat.
This is an experimental idea proposed by the physicist Xue Dinge for quantum physics.
Suppose a cat is locked in a closed box with atomic equipment.
If an atomic accident occurs, the poison will be released and the cat will be poisoned.
And whether the atomic accident is possible is not known.
If we want to know the life and death of the cat, we can only open the box.
But at this time, the problem will appear as we know it.
If we don't open the box, most people will usually think
Cats have only two possibilities.
Either alive or dead.
And we have to open the box to know the result.
...
The most short-lived in the world.
