+# Deployable radiator capacity is the binding constraint on orbital data center power scaling as evidenced by Starcloud-2's 'largest commercial deployable radiator ever sent to space' for 100x power increase
+
+Starcloud-2's mission manifest highlights the 'largest commercial deployable radiator ever sent to space' as a key enabling technology for its 100x power generation increase over Starcloud-1. This framing — radiator as headline feature alongside NVIDIA Blackwell GPUs and AWS server blades — reveals that radiator capacity, not compute hardware availability, is the binding constraint on ODC power scaling. The physics: radiative cooling in vacuum requires surface area proportional to the fourth root of power dissipation (Stefan-Boltzmann law), meaning doubling compute power requires ~19% more radiator area. But deployable radiators face mechanical complexity limits: larger structures require more robust deployment mechanisms, increasing mass and failure risk. Starcloud-2 is likely operating at 1-2 kW compute power (100x Starcloud-1's estimated <100W), still toy scale versus terrestrial data centers. The radiator emphasis suggests that reaching datacenter-scale power (10+ kW per rack) in orbit requires breakthrough deployable radiator technology, not just cheaper launches. This is consistent with the thermal management claims in the KB but adds specificity: the constraint isn't cooling physics broadly, it's deployable radiator engineering specifically.

+# Orbital data centers achieve cost competitiveness with terrestrial facilities at $500/kg launch costs according to Starcloud CEO projections for Starcloud-3
+
+Starcloud CEO Philip Johnston explicitly stated that Starcloud-3, their 200 kW / 3-tonne orbital data center designed for SpaceX's Starship deployment system, will be 'cost-competitive with terrestrial data centers' at a target of $0.05/kWh IF launch costs reach approximately $500/kg. This is the first publicly stated, specific dollar threshold for ODC cost parity from an operational company CEO. Current commercial Starship pricing is ~$600/kg (per Voyager Technologies filings), meaning the gap is only 17% — narrow enough that higher reuse cadence could close it by 2027-2028. Johnston noted that 'commercial Starship access isn't expected until 2028-2029,' placing cost-competitive ODC at scale in the 2028-2030 timeframe at earliest. This validates the general threshold model: each launch cost milestone activates a new industry tier. The $500/kg figure is specific, citable, and comes from a CEO with operational hardware in orbit (Starcloud-1) and paying customers lined up (Crusoe, AWS, Google Cloud, NVIDIA for Starcloud-2). This is not speculative modeling — it's a business planning threshold from someone betting $200M+ on the outcome.
