It’s a good picture and I also like the angle of it, sort of like an aircraft surveying the landscape or a lander taking pictures during its descent.  Shelz Keast replies: "Oh I knew about Olympus Mons, just not Valles Marineris. I get my nice big book on space on the Weekend, which will probably result in one or two more pictures in a couple of months. It’s a Christmass present that never got read before Uni." | |
