The good thing is that NASA has an up-to-date map [0] of its path, also joined by lines, which shows more of the path and also confirms how odd some stretches of its voyage have been.&lt;p&gt;Does anyone know why it spent so much time going back and forth?&lt;p&gt;---&lt;p&gt;Edit: I see, it was always going back to the &amp;quot;Sample Depot Zone&amp;quot; to deposit the collected samples. This zone is where the chaos begins after the very long stretch. Here&amp;#x27;s [1] more info on the depot, including a photo made by the rover of what such a deposited sample looks like.&lt;p&gt;---&lt;p&gt;[0] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;mars.nasa.gov&amp;#x2F;mars2020&amp;#x2F;mission&amp;#x2F;where-is-the-rover&amp;#x2F;&quot; rel=&quot;nofollow noreferrer&quot;&gt;https:&amp;#x2F;&amp;#x2F;mars.nasa.gov&amp;#x2F;mars2020&amp;#x2F;mission&amp;#x2F;where-is-the-rover&amp;#x2F;&lt;/a&gt;&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.nasa.gov&amp;#x2F;feature&amp;#x2F;jpl&amp;#x2F;nasa-s-perseverance-rover-completes-mars-sample-depot&quot; rel=&quot;nofollow noreferrer&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.nasa.gov&amp;#x2F;feature&amp;#x2F;jpl&amp;#x2F;nasa-s-perseverance-rover-c...&lt;/a&gt;</text></comment>
