The Mars Rover Opportunity considers the textures of the Santa Maria crater on its 2,746th day on Mars. There are no footprints in that sand. There may never have been footprints in that sand. Part of me hopes there will never be footprints in that sand, that it will always remain as it is – perfect, nearly liquid in its curves and peaks.
And part of me wants to run out and jump in it.
