[citation][nom]ProDigit80[/nom]On a second thought, even if we'd just abandon station,and let it rotate around the earth like the moon, it'd cost us next to nothing.Bring in some plants and perhaps one could use it as a bio plant in space!But even if we'd just abandon the station,and leave it for the next generation, that'd probably be the wisest thing to do.Just make sure it'snot going to fall into orbit with earth,and everything will be ok.[/citation]
you don't know much about orbiting objects , the space station wont just "stay" in orbit , being a smaller orbiting body it's orbit would eventualy decay and fall tot eh earth if unattended any way , bassically ending with the same result (or worse if it isnt forced into a controlled decay and strikes something other than teh ocean)
point being it's eitehr keep giving it maintance and fuel to keep it in orbit or force it down in a controlled manner , the only regretable thing is thye arnt going to sue it much before doing so
