Orbital jurisdiction provides data sovereignty advantages that terrestrial compute cannot replicate, creating a unique competitive moat for orbital data centers

ESA's ASCEND program explicitly frames orbital data centers as data sovereignty infrastructure, arguing that European data processed on European-controlled orbital infrastructure provides legal jurisdiction advantages that terrestrial compute in US, Chinese, or third-country locations cannot provide. The program's full name—Advanced Space Cloud for European Net zero emissions and Data sovereignty—places sovereignty as a co-equal objective with environmental benefits. This is NOT an economic argument about cost or performance; it's a legal and jurisdictional argument: orbital infrastructure exists in a legal framework physically distinct from any nation-state's territory. If this framing is adopted broadly by governments concerned about data sovereignty (EU, potentially other regions), orbital compute has a unique attribute that would justify premium pricing above the 1.8-2x commercial ceiling identified in the 2C-S analysis, because the alternative (terrestrial compute in foreign jurisdictions) cannot provide equivalent sovereignty guarantees regardless of price. The €300M commitment through 2027 demonstrates that at least one major governmental entity (European Commission via Horizon Europe) considers this sovereignty advantage worth substantial investment.
