Spacecraft Mass Shifting With Propellant Tank Systems

Systems, apparatuses, methods, and software are described herein that provide enhanced logistical control over spacecraft. This logistical control can include attitude adjustment and desaturation of reaction wheels. In one example, a method of operating a spacecraft includes providing propellant in two or more propellant tanks for use by at least a thruster of the spacecraft. During application of a force on the spacecraft, the method includes transferring propellant from at least a first propellant tank to at least a second propellant tank to alter a center of mass of the spacecraft.
