ELI5: why has nasa's curiosity rover only travelled 10 miles in the space of 5 years.

Because its goal isn't to travel; it already landed where it needed to be. It drives a few inches, takes pictures and soil samples and does related testing. It would need to travel really long distances in order to get to someplace that different, geologically speaking, and it's just not worth it. There's plenty of interesting things right where its at.

Also, we've sent other rovers to different parts of the planet. *Spirit* was active from 2004 to 2010 and its sister rover (which landed on the other side of the planet), *Opportunity*, is still going.
