This image provided by NASA, assembled from a series of January 2018 photos made by the Mars Curiosity rover, shows an uphill view of Mount Sharp, which Curiosity has been climbing. Spanning the center of the image is an area with clay-bearing rocks that scientists are eager to explore; it could shed additional light on the role of water in creating Mount Sharp. On Thursday, March 2, 2018, NASA’s Mars rover Curiosity marked 2,000 days on the red planet by Martian standards. A Martian sol, or solar day, is equivalent to 24 hours, 39 minutes and 35 seconds. So 2,000 days on Mars equal 2,055 days here on Earth.
