Several years back NASA issued a warning on the slow progress of this mission. Their main objective was to traverse the sedimentary layers up Mt. Sharp. They havent really begun the climb yet. A long, dangerous sand dune caused a couple year delay. Plus lots of investigative stops along the way. The power will last 20 years. The wheels are damaged from being too thin. If funding becomes tight, other missions will have precedence. https://www.washingtonpost.com/news/speaking-of-science/wp/2014/09/04/nasa-hurls-insults-at-curiosity-the-worlds-favorite-rover/ https://www.washingtonpost.com/news/speaking-of-science/wp/2...
