Two images of the Nili Plateau landscape to the west of the rover: one taken at about 1:30 PM local time, the other at about 7 PM, in early summer.
The evening shadows really give the landscape a definition and intrigue which the hazy afternoon sun barely hints at, with even small pebbles standing out, and those sandy mega-ripples down below much more easily identified in the distance.
OTOH, I find that the rover tracks (on the right) become harder to see in the evening, so your hiking skills and common sense are key on late-day excursions. You definitely don’t want to be lost in this landscape after dark as temperatures quickly head for -100 ºC…
Bring twice as much water as you think you’re gonna need.
And an extra jacket, as it get a bit nippy after sunset ;)
