Abstract

  • Orbital data centers (ODCs) are moving from concept to near-term engineering: Starcloud (5 GW), Meta / Overview Energy (1 GW SSP), SpaceX (up to 1M-satellite FCC filing).
  • Multi-kW to GW-class compute demands solar arrays of unprecedented scale → extreme inertia and disturbance torques.
  • Can Reaction Wheels (RWs) vs Control Moment Gyroscopes (CMGs) hold an ODC in a sun-nadir pointing profile?
