Were can i get/make a Mars Material

Take a rocky desert material, tint the textures with a slightly red color. Whola!

If you want to do it more advancedly - get rocky desert material with cracks, tint it, contrast up the roughness map(to get slightly glossier surfaces), try strengthening normals. If you wanna learn how to make those textures yourself, use your friend google. You can easily find some nice and free tutorials of many topics.

Note that you will want to have height map and use tesselation to achieve the effect seen in video.
