Opportunity Rover Survives Worst Part of Another Martian Winter As It Continues Study of Ancient Gully
As incredible as it is to believe, NASA’s Opportunity rover is still going strong on Mars, nearly fourteen years after landing in January 2004. And now once again, it has just passed the shortest daylight time of the Martian year, the worst part of the Martian winter, with pretty clean solar panels to boot. Unlike the newer Curiosity rover which uses nuclear power, Opportunity, and its now-dead twin Spirit, uses solar panels for energy. At the same time, the rover continues to study an ancient gully thought to have been carved by water in the distant past.
