Why might mission planners investigate nuclear fission power systems over solar power for a reliable Martian surface supply?

Answer

Solar power might be unreliable because dust storms can last for months.

Because Martian dust storms can persist for months, mission planning investigates more consistent power sources like nuclear fission power systems to ensure a reliable surface power supply.
