The sand bank is currently blocking the robot's path into a small valley and a route with fewer of the sharp rocks that lately have been making big dents in the vehicle's aluminium wheels.
US space agency engineers will take no risks, however. The rover will be commanded initially to climb only part way up the dune to see how it behaves.
The team is mindful that Nasa's Spirit rover was lost in a sand trap in 2009.
I find it interesting to note that NASA does not put that b/s red hue on the pictures any more.
Looks kind of familiar now.
Life is like a penny, you can spend it on what you like, but you can ONLY spend it once.
