# Orbital AI data centers face a decade-long cost parity gap with terrestrial compute because radiation hardening, latency, and launch economics favor Earth-based infrastructure through at least the mid-2030s

Deutsche Bank projects cost parity between orbital and terrestrial compute 'well into the 2030s,' contradicting Musk's 2028-2029 timeline. The cost gap persists despite Starship economics for three structural reasons: (1) Radiation hardening imposes 30-50% cost premium and 20-30% performance penalty on orbital hardware (established in KB), with no servicing possible — failed components become debris or require expensive deorbit. (2) Latency penalties: orbital data centers at 500-2000 km altitude add 2-10ms minimum round-trip time, limiting use cases to defense, remote sensing, and sovereign compute rather than general-purpose training. (3) Thermal management remains unproven at datacenter scale — radiative cooling requires 1200 square meters of radiator per megawatt (established in KB), and microgravity eliminates convection-based cooling used in terrestrial facilities. Tim Farrar characterizes the FCC filing as 'quite rushed' and likely a 'narrative tool' for SpaceX's IPO rather than near-term operational plan. The filing's timing (3 days before merger announcement) and scale (1 million satellites requiring 44x current launch cadence, per KB) suggest regulatory positioning rather than technical readiness. Current proven use cases remain limited: on-orbit processing of satellite data (validated), edge compute for military applications (operational as of January 2026 per KB), but not competitive general-purpose cloud compute or AI training.


## Supporting Evidence

**Source:** Deutsche Bank space research team, February 2026

Deutsche Bank analysis projects orbital/terrestrial compute cost parity 'well into the 2030s' - approximately 5-7 years later than Musk's 2028-2029 projection. The gap is driven not just by launch costs (which Starship addresses) but by unsolved problems in compute density in radiation environments: radiation-hardened chips are currently 10-100x more expensive and 10-100x less dense than commercial equivalents, and no commercial radiation-hardened GPU exists.
