The right choice
With dust accumulating on Opportunity's solar panels, now is the time for this dramatic exploration. There's lots to see inside the crater and chances are, the little rover that could is getting close to "can't." If she survives to regain the plains of Meridiani, more power to her. But she has already exceeded our expectations beyond our wildest dreams.
God speed Opportunity. Take a drink of the abyss of Endurance and tell us how it tastes.
