An animation showing the 1.255 light second distance between us and the moon (the Sun is about 8 light minutes from us) created by planetary scientist Dr. James O’Donoghue using NASA imagery. and that’s not all. To wit:
This is the distance between the Earth and Moon with the correct sizes and scales. The real-time speed of light is also shown.
Who is to say what surface is to be kept graffiti clean? My personal concern is that this will be a reality some day and speaks to a larger issue of our relationship with the natural world. The satellite and space graffiti hints that even if we colonize other worlds, what mark will we leave? No matter where we go there is evidence of our presence.
