Google thinks SpaceX’s Starship has to launch 1,800 times before space datacenters get off the ground
Google's orbital compute satellite successfully launched aboard a SpaceX rocket, marking the first test of its Tensor Processing Unit in space. The company envisions a future of satellite networks requiring substantial launches, estimating 1,800 to make space data centers viable. Their analysis predicts a dramatic fall in launch costs, although achieving necessary future launch rates remains uncertain.
Key points
- Google's satellite is testing Tensor Processing Units (TPUs) in space for advanced computing.
- The satellite will run on limited power and aims to prove TPUs can handle workloads in orbit.
- Project Suncatcher plans for a network of 81 satellites working collaboratively.
- To lower launch costs, SpaceX needs to complete 1,800 launches over ten years.
- Google expects the price of launching to decrease to approximately $200 per kilogram by 2035.
Why it matters
- The trajectory of reduced launch costs is tied to the broader trends in space commercialization.
- Google's initiative reflects increased investments in space AI and the growing importance of computation in orbit.
- The need for cost-effective space infrastructure aligns with predictions of satellite and space technology advancements by 2025.
The successful launch of Google's satellite could herald a new era for computational workloads in space, contingent on ambitious future launch goals from SpaceX and the evolution of orbital infrastructure.
