That's more or less what they used to do with Sojourner, only with humans setting out the way points rather than A* . It never managed to get more than 10 meters from its lander though, I assume this was partly driven by the limitations on a human's patience in operating a slow vehicle with 28 minute feedback loop. One drawback of the remote A* approach is that you end up using more energy as the rover would have to be constantly communicating with its onboard antenna. Its relay satellites are only in range for a limited period each day. Fine grained maneuvers (like drive around that big rock to get to this small rock) would also prove difficult because of likely errors in the rover's inertial-navigation system. https://en.wikipedia.org/wiki/Sojourner_(rover) https://en.wikipedia.org/wiki/Sojourner_(rover)
