In early 2004 Mars Exploration Rover – B, better known as Opportunity, landed on Mars and began its 90 day mission. 14 years later, it continues to map the martian surface. It has survived 8 martian winters, outlived its twin rover, Spirit, by 8 years, and weathered numerous sandstorms.Recently, the worst recorded sandstorm began, covering nearly a quarter of the red planet's surface and blocking 90% of the light. Opportunity has not seen the sun in days and has switched into hibernation mode, spending no power other than keeping its mission clock running and periodically checking its battery charge levels. This means no motor functions, no communications, and most importantly no heater. Even if the storm ends and Opportunity's solar panels are blown clear of dust by cleaner winds, its batteries may have suffered too much damage from extended exposure to Mars' cold air.We may have already recieved Opportunity's last transmission.Rage on, wild rover. Rage against the dying of the light.Written in Circular Gallifreyan , fan made alphabet by
