Ok, i'm gonna take a stab at this. I have a rover design i'm pretty confident in. Gonna use MechJeb as I CBF driving it manually. My newest rover 'innovation' has been to include landing gear in addition to powered wheels. This means if power is low, I am going downhill, or there is a risk of a hard landing, I can deploy the gear & prevent the tyres from popping. I think I will start with Duna, as I quite like the planet. Day 1: Landed approx 72Sx78E, heading north. Debris from my skycrane will be taken as my point-of-reference. Planting flags every 20km or so, heading due north. 4 flags and 67 km later, stopped for the night. Day 2: Still heading north. Passed 45S, starting to get red sand. Approx 167 km away from landing site, 9 flags.
