Rank 13 documents Spirit (MER-A) at the centre of NASA's twin Mars Exploration Rover campaign — the January 2004 landing that proved Gusev Crater held volcanic basalt worth climbing and that solar-powered rovers could survive global dust storms by parking on north-facing slopes. Spirit carried Pancam stereo cameras, a Rock Abrasion Tool, and Mössbauer spectrometer on a 185 kg rocker-bogie chassis designed for 90 sols but operated 2,208 sols until stuck in soft soil at Troy in 2009; last contact came 22 March 2010. Steve Squyres' science team and JPL's Callas engineering group turned MER-A into a Columbia Hills traverse story — Home Plate silica, Comanche outcrop, and the heat-shield bounce imaging that made descent hardware part of the archive. Wallimilist renders the circular hero, dust-panels rover, and Gusev landing footer exactly as the master PNG dictates — 2004 kicker, Mars Exploration Program seal, and curator copy on twin-rover heritage.
