Yellowknife Bay, Mars the Glenelg member and began its journey to Mount Sharp. NASA scientists estimated this drive would take the rover a year to complete. Yellowknife Bay, Mars Yellowknife Bay is a geologic formation in Gale Crater on the planet Mars. NASA's Mars Science Laboratory Rover, named "Curiosity", arrived at the low lying depression on December 17, 2012, 125 sols, or martian days, into its 668 sol planned mission on the planet. Primary mission goals of the Mars Science Laboratory were to assess the potential habitability of the planet and whether or not the Martian environment is, or has ever been, capable
Mars Exploration Rover Mars Exploration Rover NASA's Mars Exploration Rover (MER) mission is an ongoing robotic space mission involving two Mars rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the launch of the two rovers: MER-A "Spirit" and MER-B "Opportunity"—to explore the Martian surface and geology; both landed on Mars at separate locations in January 2004. Both rovers far outlived their planned missions of 90 Martian solar days: MER-A "Spirit" was active until 2010, while MER-B "Opportunity" is still active in 2018, and holds the record for the longest distance driven by any off-Earth wheeled vehicle. The mission's
