Have a look at these:
Pic of the Serpent Dust Devil of Mars
Pathfinder on Mars
Mars albedo image showing light reflected from the sun. The scale is from zero to one with one being total reflection, zero is none.
Dual Crater is caused when meteorite breaks into 2 parts before impact.
Light Toned Deposit in Aureum Chaos
Craters on an Icy Surface
Crater near Sirenum Fossae
Drag Folds in the North Polar Layered Deposits
Changing Dunes and Ripples in Olympia Undae
Ares Vallis, teardrop formations behind crater.

Amazing blue pic of Cyclic Bedding within a Crater in Arabia Terra on Mars.
Hole on surface due to unknown.
Small Channels and a Rocky Patch in the Cydonia Region
Impact crater in Isidis Planitia close up.

Nice looking Gale Crater pic showing a new face in this mosaic image made using data from the Thermal Emission Imaging System. The colors come from an image processing technique that shows mineral differences in surface materials and displays them in false colors.
South Pole as viewed by Mariner 9
Global view of Mars in low energy(thermal, neutrons).
Lyot Crater (220-kilometers in diameter), image from NASA
Cute pic of the Sun from Mars. It is so far away it looks tiny.
Recurring Slope Lineae in Raga Crater
Enhanced color image of the heavily windblown dunes, channeled and ancient southern highlands of Mars.
Cool Image of Ancient Lake Sediments
Photo showing erosion on surface.
You can view the Red Planet with a decent telescope.
