# Orbital data centers are activating bottom-up from small-satellite proof-of-concept toward megaconstellation scale, with each tier requiring different launch cost gates rather than a single sector-wide threshold

The Two-Gate Model predicted orbital data centers would require Starship-class launch economics to clear Gate 1 (proof-of-concept viability). However, Starcloud-1's November 2025 launch demonstrated successful AI model training and inference in orbit using a 60kg satellite deployed via SpaceX Falcon 9 rideshare at approximately $360K-600K total launch cost. The satellite successfully trained NanoGPT on Shakespeare's complete works and ran Google's Gemma LLM with no modification to Earth-side ML frameworks, delivering ~100x more compute than any prior space-based system. This proves that proof-of-concept ODC cleared Gate 1 at CURRENT Falcon 9 rideshare economics, not future Starship economics. The pattern suggests ODC is activating in tiers: small-satellite proof-of-concept (already viable at rideshare rates) → medium constellations (requiring dedicated Falcon 9 launches) → megaconstellations (requiring Starship-class economics). Each tier has its own launch cost gate, rather than the sector waiting for a single threshold. This mirrors how remote sensing activated through CubeSats before Planet Labs' constellation before future hyperspectral megaconstellations. The tier-specific gate pattern means sectors can begin generating revenue and operational data at earlier, higher-cost tiers while waiting for lower tiers to unlock.
