"Given the sheer mass of the structure, and the slow manner with which things change here, this inukshuk may well be standing 500 years from now. That should be long enough. Maybe someone serving on a starship will think to visit it."
"To the friends and families of these lost space travelers, these inukshuks offer a silent thank you - one amplified by the austere remoteness of this place - a remoteness you have to spend a lot of effort to visit. Right now, space travel is just like that. Hopefully that will change one day."
