I had a chance to work on the legendary Kim Stanley Robinson's trilogy about terraforming Mars aka 'how to colonise Mars in three steps' for the Science-Fiction Classics series of İthaki.
My final concept is based on highlighting the three different stages of the whole journey. I support the idea by adding tiny clues with icons per cover. There are only three elements on all covers which are static, could you guess what are they representing?
