Power Management is of
Preeminent Importance
Power availability affects all aspects of deployed
internet operation
Solar conversion is the primary power source for
foreseeable future
Example:  The average solar intensity in Mars orbit is
590 W/m2, compared with 1370 W/m2 in Earth orbit
Surface-based solar panels are subject to
Atmospheric dust limiting available solar energy
Dust build-up on/erosion of solar panels, reducing
effectiveness over time
Location-based reductions in solar intensity
Seasonal variations in solar intensity
Efficiency of communication at all layers is
required to offset the limitations of power
availability
